Hot Plate For Gas BBQ: 7 Best Picks For UK Gardens (2026)

Picture the scene. It’s a drizzly bank holiday, the bacon is wedged between grate bars, and half your mushrooms have just dropped into the burner tray. That’s the moment most Brits start shopping for a hot plate for gas BBQ.

A solid griddle turns your barbecue from a sausage-and-burger machine into an outdoor kitchen. Eggs, pancakes, onions, smashburgers and a full fry-up all become possible. For most people it’s also the cheapest upgrade going.

The catch is fit. Weber, Char-Broil, Broil King and Napoleon each use different grate layouts, so the wrong plate simply won’t sit properly. This guide compares seven real options and explains what the specs mean in practice. It also covers care, seasoning and safety.

Reviewer evidence is patchy for some of these products, and I’ll say so plainly rather than dress it up. Prices are given as ranges, because they move around and vary by retailer.

If you’re searching for a replacement hot plate BBQ owners can trust, or planning breakfast on BBQ for the first time, you’re in the right place.

What Is a Hot Plate for Gas BBQ?

A hot plate for gas BBQ is a solid, flat cooking surface that sits on or replaces part of your grill grates. It’s usually made from cast iron, steel or enamel-coated metal. It lets you fry, sear and sauté food that would otherwise fall through the bars.

It spreads heat evenly, contains fat and sauces, and suits small or delicate food. It’s the closest you’ll get to a frying pan built for your barbecue.

Most come in two flavours: inserts that swap in for a grate section, and plates that sit on a side burner. Surfaces are either bare metal or porcelain-enamelled, and the difference matters. Raw cast iron needs seasoning, a baked-on layer of polymerised oil that stops sticking and rust. Enamelled plates are coated at the factory, so they need far less ritual. They aren’t entirely maintenance-free, though, as we’ll see.

Quick Comparison: Seven Hot Plate for Gas BBQ Options

Here’s the shortlist at a glance. Compatibility is the make-or-break column, so check it before anything else.

The cheapest route is a brand-matched insert such as the Weber GBS Cast Iron Griddle Insert or the Broil King Reversible Cast Iron Griddle. They sit in the £50s and need no extra kit. The Weber Crafted Griddle asks you to own Weber’s Crafted frame and grates first, which is a real extra cost. The Char-Broil Griddle 3400 is a different category entirely, since you’re buying a whole barbecue.

Top 7 Hot Plate for Gas BBQ Picks: Expert Analysis

1. Weber Crafted Griddle — premium fit for Weber Crafted systems

The standout here is the rimmed edge. It keeps oil and seasoning from migrating into the burner box, which is exactly the problem most flat plates suffer from.

The plate is porcelain-enamelled cast iron, 40 cm wide and 41.5 cm deep, and it needs Weber’s Crafted frame and grates. It fits Genesis 2022+ and SmokeFire EPX4/EPX6. Older Genesis and Spirit models (2016–2021) can use it with Weber’s separate frame kits (#7687 and #7688). Cast iron holds heat well, so a cold egg or pancake batter doesn’t crash the surface temperature.

Based on the spec sheet, this is for existing Weber Crafted owners who want a seamless upgrade. Anyone else would be paying for an ecosystem they don’t have.

On Weber’s UK site, reviewers rate it highly, around 4.8 out of 5 from just over 100 reviews at the time of research. The comments are mostly about versatility. One lukewarm review actually complained about the barbecue’s ignition and gas-bottle door, not the plate.

Pros:

• ✅ Rimmed edge keeps oil contained
• ✅ Heavy cast iron retains heat brilliantly
• ✅ Seamless fit with Crafted-ready Webers

Cons:

• ❌ Needs Crafted frame and grates
• ❌ Hand-wash only

Price: check current price. Expect it to sit at the premium end, and it only makes sense if you already own the right Weber.

2. Weber GBS Cast Iron Griddle Insert (7421) — easiest budget upgrade for Weber GBS grates

The big selling point is simplicity. It drops into the lift-out central section of Weber Gourmet BBQ System grates, so there’s no frame kit to buy.

It’s porcelain-enamelled cast iron and designed to replace a 30 cm central section. Retailers describe it as good for prawns, mushrooms, eggs and pancakes, and as an even-heat crust-maker for steaks and smashburgers. Because it’s enamelled, you’re not committing to a full seasoning ritual. Just follow the care instructions.

Analytically, it suits Weber owners who want a flat surface without paying for a whole system. Its limit is size, since the insert is cut to the central section. A big family fry-up needs batches.

I couldn’t verify a reliable pool of independent review data for this exact model at the time of research. Treat compatibility with your specific grate as the main due-diligence step.

Pros:

• ✅ Drops straight into GBS grate sections
• ✅ Porcelain enamel eases cleaning
• ✅ Good value for the Weber ecosystem

Cons:

• ❌ Only fits compatible Weber grates
• ❌ Limited surface for large batches

Price: mid-£50s at UK specialist retailers. Good value if your grates match.

3. Char-Broil Cast Iron Griddle/Grill Plate 37cm — side-burner breakfast on a budget

This one’s clever because it doesn’t touch your main grates at all. The porcelain-coated cast iron plate sits on a Char-Broil side burner, so you can fry bacon while burgers cook on the main grill.

It measures roughly 37 cm wide and 27 cm deep, and it’s about 7 cm high. That’s the size of a large frying pan, not a griddle for a crowd. For two to four people, though, it’s a sensible footprint. Cast iron holds heat, so you can sear and then ease back.

The honest analysis: it’s for Char-Broil owners who want a dedicated frying station, particularly for breakfast on BBQ. The limit is that it’s designed for Char-Broil side burners. Check yours before buying.

At the time of research, the product page showed a perfect average but from only three reviews. That’s far too small a sample to draw conclusions, so treat it as encouraging rather than proven.

Pros:

• ✅ Frees main grates for other food
• ✅ Porcelain coating cuts seasoning faff
• ✅ Frying-pan-sized and easy to store

Cons:

• ❌ Needs a compatible Char-Broil side burner
• ❌ Too small for big groups

Price: around £50. Decent value if your barbecue has a side burner.

4. Broil King Reversible Cast Iron Griddle (11237) — two cooking styles in one plate

The hook is the reversible design. One side is smooth for frying, the other ribbed for searing, so a single purchase covers eggs and steaks.

It’s heavy-duty cast iron with a matte porcelain coating, made for Porta-Chef and Gem series barbecues. It replaces a section of the cooking grids with an exact fit. The ribbed side gives you grill marks and drains fat away from food, while the flat side handles pancakes and onions.

Analytically, it’s a smart pick for smaller three-burner Broil King owners who want one accessory to do two jobs. The flip side is that you’ll need to store or clean both faces.

I couldn’t verify a strong bank of independent UK reviews for this exact code. One forum owner of a Broil King 310/320 mentioned the flat griddle add-on as a worthwhile option, which is anecdotal but encouraging.

Pros:

• ✅ Reversible: flat for frying, ribbed for searing
• ✅ Exact fit replaces grate sections
• ✅ Porcelain coating helps cleaning

Cons:

• ❌ Fits only specific Broil King ranges
• ❌ Heavy to lift and clean

Price: £55–£60 range at UK retailers. Strong versatility for the money.

5. Broil King Imperial XL/Regal Cast Iron Griddle (11239) — bigger surface for bigger households

The main draw is surface area. It suits larger Broil King barbecues, so a full cooked breakfast for the family doesn’t mean three rounds of frying.

It’s reversible cast iron like its smaller sibling, with a smooth side and a ribbed side. The extra size means you can run a hot zone and a cooler zone, because the plate has room for both. That matters with eggs, which scorch the moment you leave them over direct heat.

The honest take: it’s a sensible upgrade for Imperial XL and Regal owners who regularly cook for four or more. Everyone else will pay extra for a plate they don’t need.

Again, I couldn’t verify solid review data for this specific code, so compatibility and expectations are your main checks. Broil King’s wider range has a decent reputation among UK barbecue forums, but that’s general sentiment, not proof about this plate.

Pros:

• ✅ Large reversible surface for families
• ✅ Heat-retaining cast iron
• ✅ Matches Imperial XL/Regal layout

Cons:

• ❌ Only fits specific Broil King models
• ❌ Dearer than smaller inserts

Price: mid-to-high £80s. Worth it only if you cook for crowds.

6. Napoleon Enamelled Cast Iron Reversible Griddle (56041) — drainage holes for crispy bacon

The unusual feature is a set of small drainage holes in the flat side. They let grease drip away, which is what makes sausages and bacon crisp rather than stewed.

The plate measures 33 × 45.1 cm. It’s two-sided, with a flat matte side and a raised glossy “Wave” side, and it’s porcelain-coated cast iron. Napoleon lists it for PRO/Prestige 500 and 665 plus LEX 485, 605 and 730 grills. Another Napoleon griddle variant exists for Rogue and Freestyle models, so match the code to your barbecue.

It suits Napoleon owners who see breakfast as a serious outdoor meal. The trade-off is that drainage holes make it less suited to wet batters and runny eggs.

I couldn’t verify strong independent review data at the time of research. On Napoleon’s European sites, the list price sat roughly in the €70–€90 range, so expect a broadly similar sterling figure but check current price.

Pros:

• ✅ Drainage holes help crisp bacon
• ✅ Large surface with reversible design
• ✅ Porcelain-coated cast iron

Cons:

• ❌ Model-specific fit needs careful checking
• ❌ Holes make runny eggs messy

7. Char-Broil Griddle 3400 — the all-in flat-top option

The standout is that it isn’t an accessory at all. It’s a complete gas barbecue with a 48 × 68 cm porcelain-coated cast iron plate and three burners.

The plate is one piece, with a grease tray fed by a drain in the griddle. Maximum temperature is stated at 370°C, and it has electronic ignition plus a gas hose and propane regulator. The overall size is about 165 cm wide, 72 cm deep and 93 cm high, so it needs a proper patio.

For anyone who’d rather cook smashed burgers, tacos and French toast than grill steaks, this is the most direct route. The trade-off is that you lose conventional grate marks entirely.

I couldn’t verify trustworthy aggregated review data for this model, and that’s worth knowing before you spend serious money. Compare it against your actual cooking habits first.

Pros:

• ✅ Huge one-piece cast iron plate
• ✅ Grease tray makes cleaning easier
• ✅ Includes regulator and hose

Cons:

• ❌ Needs substantial patio space
• ❌ No traditional grill marks

Price: check current price. It’s a full barbecue, so it sits in a different budget bracket from the inserts.

Breakfast on BBQ: A Step-by-Step Fry-Up Guide

Breakfast on BBQ is where a hot plate for gas BBQ earns its keep. The trick is zones. Run one side hot and one side gentle, because bacon, sausages and eggs all want different heat.

Step 1: Preheat gently. Give your plate 10–15 minutes on medium. Cast iron heats slowly and unevenly if you rush it.

Step 2: Start with the slowest items. Sausages go on first, because they need the longest. Move them to the cooler edge once they’ve coloured.

Step 3: Add bacon. It needs a hotter patch and plenty of room, because crowding steams rather than crisps.

Step 4: Eggs and beans last. Brush the cooler zone with a little oil and crack the eggs straight on. A heatproof ring helps keep beans from sliding into everything else.

Step 5: Rest and serve. Keep cooked food warm at the plate’s cooler edge, away from raw items.

If you’re building a hot plate for fry-up on BBQ routine, aim for a plate that’s at least 30 cm across. Anything smaller turns into a batch-cooking exercise. Always use separate utensils for raw and cooked food, and cook sausages until they’re steaming hot all the way through.

Gas BBQ Maintenance: Keeping Your Hot Plate and Burners Healthy

Gas BBQ maintenance sounds dull, but it protects both your food and your investment. A hot plate adds a few extra jobs to the usual routine.

Weber’s own maintenance guidance suggests wiping the exterior monthly and giving the interior a thorough clean about every three months if you grill regularly. It also recommends checking the gas hose and regulator regularly, and doing a gas leak check after cleaning or moving the barbecue. That’s sensible baseline advice for any brand.

After every cook: let the plate cool a little, scrape off residue, wipe with hot water and dry it completely. Enamel is robust but not indestructible, so avoid sudden cold-water shocks on a hot plate.

Monthly: empty and clean the drip tray, and check for chips in the coating. A chipped enamel edge is where rust starts.

Seasonally: deep-clean burners and inspect hoses and fittings. If flames look weak or yellow, it’s usually a sign of blocked burner ports.

Storage: keep plates dry and lightly oiled if they’re bare cast iron. Enamelled plates still benefit from being stored out of the damp, because British winters are unkind to anything left outdoors.

Problem → Solution: Fixing Common Hot Plate Headaches

Problem: food sticks. Usually the plate wasn’t hot enough or wasn’t oiled. Preheat properly and add a thin film of oil. On bare cast iron, build seasoning by cooking fatty foods regularly.

Problem: rust spots. They appear when moisture sits on bare iron or on a chipped enamel edge. Scrub off the rust, dry thoroughly, and re-oil. If enamel is chipped extensively, that’s a sign you may be heading toward grill plate replacement.

Problem: grease flare-ups. Fat dripping onto burners is the culprit. A rimmed plate like the Weber Crafted Griddle, or a grease-channelling design like the Char-Broil Griddle 3400, reduces this. Otherwise, keep the drip tray clean and don’t overload with fatty food.

Problem: uneven heat. Cold and hot patches usually come from dirty burner ports or a plate that doesn’t sit flush. Clean the burners and check the plate seats properly in its frame or grates.

Problem: eggs run off. A flat plate with a lip, such as the Broil King Reversible Cast Iron Griddle, helps. A heatproof ring is the cheap fix.

How to Choose a Hot Plate for Gas BBQ

Choosing the right hot plate for gas BBQ is mostly about avoiding mistakes. Work through these steps in order.

1. Check your barbecue model first. Brand and series matter more than anything else. A plate that doesn’t fit is a paperweight.
2. Decide insert, side-burner plate or whole barbecue. Inserts replace grate sections, side-burner plates add a second cooking zone, and a flat-top barbecue changes everything.
3. Pick your material. Porcelain-enamelled cast iron is easiest to live with. Bare cast iron and steel need more care but can be tougher.
4. Match size to your household. A 27–30 cm plate suits two; for four or more, look nearer 40 cm and beyond.
5. Look for features that earn their place. Rimmed edges, drainage channels and reversible faces solve real problems.
6. Weigh the weight. Cast iron is heavy to lift and clean. If that’s a concern, factor it in.
7. Read recent reviews and check availability. Compatibility notes in reviews are gold dust.

Replacement Hot Plate BBQ and Grill Plate Replacement: When and How

A replacement hot plate BBQ purchase is usually triggered by wear, not whim. Signs include flaking or chipped enamel, deep pitting, warping that stops the plate sitting flat, and rust you can’t scrub out.

Grill plate replacement is easiest when you stay within your barbecue’s own range. The Weber GBS Cast Iron Griddle Insert and the Broil King Reversible Cast Iron Griddle both suit this approach because they’re built for specific grate layouts. Universal plates exist, but cheap ones can be thin, which means hot spots and warping.

Before ordering, measure your grate section and note your model number. Compare it with the manufacturer’s compatibility list, not a retailer’s summary alone. If you’re replacing a plate on an older barbecue, check that the manufacturer still lists the part, because ranges change.

Think about whether to repair instead. Light surface rust on bare cast iron can often be scrubbed and re-seasoned. Extensive enamel loss is harder to fix. Once the metal is exposed in many places, replacement is usually the sensible route.

Enamel Hot Plate for Gas Grill vs Bare Cast Iron vs Steel

An enamel hot plate for gas grill gives you a coated, smoother-feeling surface from day one. The coating is porcelain, baked onto the metal. It resists rust and eases cleaning, but it can chip if you knock or shock it.

Bare cast iron relies on seasoning. Once you’ve built it up, it’s wonderfully non-stick and tough, but the upkeep is yours. Steel plates are lighter and heat quickly, though they’re less forgiving of heat swings than heavier cast iron.

The table shows why most products on this list are porcelain-enamelled: it’s the least fussy route for most households. Bare cast iron suits people who enjoy the ritual, and steel suits anyone who wants lighter handling. If you’re undecided, enamelled cast iron is the safest compromise.

What to Expect: Real-World Performance for a Hot Plate for Fry-Up on BBQ

A hot plate for fry-up on BBQ behaves like a heavy frying pan with a very large footprint. Expect a slow, steady warm-up, then excellent heat retention once it’s up to temperature.

On paper, cast iron’s thermal mass means food stays hot-seared even when you add something cold. That’s why a smashburger gets a proper crust. The flip side is slower response: turning the burners down won’t cool the plate quickly.

Wind and weather matter too. A breezy British morning can cool a plate’s edges, so shelter the barbecue if you can. Lids help on some designs, but check your manual before closing anything over a plate.

For real-world planning, think in batches. A 33 × 45 cm plate like the Napoleon 56041 handles breakfast for a small family in one go. The 37 cm Char-Broil 37cm Plate suits two to four people. Anything bigger is where the Char-Broil Griddle 3400 earns its place.

Long-Term Cost & Maintenance: Is a Hot Plate for Gas BBQ Worth It?

Per use, a hot plate is one of the better-value barbecue additions. A plate in the £50s costs around £5 per cook if you use it ten times, and the cost per cook keeps falling. A well-cared-for enamelled plate can last many seasons.

The hidden costs are cleaning supplies, oil and, eventually, replacement. Cheap plates may need replacing sooner, which can wipe out the initial saving.

Over several seasons, the mid-priced inserts offer the best balance of cost and flexibility. The full griddle barbecue only pays off if you’d otherwise avoid grates altogether. Buy to your actual cooking habits, not to a wish list.

Hot Plate Safety and Food Hygiene on a Gas BBQ

A hot plate doesn’t change the basic rules of barbecue safety. The Food Standards Agency’s barbecue guidance stresses cooking food thoroughly and avoiding cross-contamination. Check that food is steaming hot throughout, with no pink meat and clear juices. Minced products such as sausages and burgers must be cooked all the way through.

Keep raw and cooked food apart. Use separate utensils and plates, and never put cooked food back on a plate that’s held raw meat. A hot plate’s flat surface makes it tempting to push everything together, so keep a clear raw zone and a cooked zone.

On the gas side, close the cylinder valve after cooking, not just the burner knobs. Check hoses and fittings regularly and carry out a leak check after moving or cleaning the barbecue. Look for UKCA or CE marking on the barbecue itself, and always follow the manufacturer’s guidance for accessories.

Finally, remember that enamelled plates can chip. Never use a plate with a flaking coating for food, and replace it if the damage is widespread.
