If you love the flavour and speed of hot-plate cooking, the Weber Slate 3 Burner Griddle (30") LPG is built to make it easy. You get a generous 30" (76 cm) flat cooking surface with three burners underneath, so you can sear hard, cook steady, and keep food warm — all at the same time. It’s a brilliant option for family dinners, weekend entertaining, and anyone who wants one cooking surface that can handle the whole meal.
Edge-to-edge heat and over-260°C searing
Griddle cooking lives or dies by heat consistency. This griddle is designed to heat evenly across the plate and reach high temperatures (over 260°C) for crisp edges and proper browning — the secret to smash burgers with a crust, prawns that don’t stew, and veggies that caramelise instead of going soft.
Three-burner zone control for fast meals
Three burners means you can set up real cooking zones without overthinking it:
-
High heat for searing burgers, steaks, prawns, and quick-cook proteins
-
Medium heat for steady cooking like chicken, stir-fries and fajitas
-
Lower heat for toasting buns, warming tortillas, or holding the first batch hot
It’s the easiest way to cook for a group without batch cooking and stress.
Ready-to-cook carbon steel cooktop
The cooktop is rust-resistant carbon steel and comes pre-seasoned so you can start cooking straight away. Over time, light maintenance and regular use helps the surface continue to perform at its best — smoother cooking, better release, and more reliable results.
Weber Slate 3 Burner Griddle (30") LPG keeps clean-up quick
No one wants a massive clean-up after a good feed. The front-facing grease tray makes it easier to manage grease as you cook and tidy up afterwards. A warm scrape, a quick wipe-down, and you’re ready for the next cook.
Cook without a lid: the top cover is for storage only
This griddle is designed to cook without the lid down. The hinged top cover is for storage purposes and should only be lowered once the gas is turned off and the unit has completely cooled.
LPG set-up notes
This model runs on LPG with a refillable cylinder (sold separately). It’s supplied with the manufacturer’s hose and regulator setup — always connect and use outdoors in a well-ventilated area, following the supplied instructions. (It’s also not intended for commercial use.)
