At a glance

The Weber Slate 3 Burner Griddle 30" is a freestanding LPG gas griddle built for families and home entertainers who want a large, even-heating cooking surface for breakfasts, burgers and batch cooking. Its pre-seasoned carbon steel plate, 38 MJ output and practical shelf make it easy to use outdoors. The main trade-off is that it is a dedicated flat-top cooker, so it is less versatile than premium multi-purpose BBQs with grills or side burners.

What it’s great for

  • Family BBQs
  • Outdoor Entertaining
  • Breakfast Cooking
  • Batch Cooking
  • Burgers and Searing
  • Flat-Top Cooking

Where it works best

  • Backyard Patios
  • Alfresco Areas
  • Outdoor Entertaining Spaces
  • Family Homes

Who it’s for

  • Families
  • Home Entertainers
  • Weekend Cooks
  • Flat-Top BBQ Fans

Things to consider

This model focuses on griddle-style cooking, so it does not offer the grilling flexibility of premium gas BBQs that include open grates, roasting setups or extra side burners.

Entertaining suitability

High - the large plate and even heat make it well suited to cooking for groups

Family size fit

Medium to large families

Outdoor space compatibility

Best for medium to large outdoor areas

Ease of cleaning score

8/10 - flat-top carbon steel surface is straightforward to scrape and wipe down, but ongoing seasoning care is still required

Portability rating

3/10 - freestanding format is practical in place, but the 64 kg build is not ideal for frequent moving

Key benefits

  • Pre-seasoned carbon steel cooktop: Ready to cook with a surface designed for consistent contact cooking and easier food release once maintained properly.
  • Rust-resistant cooktop: Helps the plate stand up better to outdoor use and regular cooking sessions.
  • 3480 cm2 cooking area: Provides enough room to cook multiple items at once for family meals or entertaining.
  • Three-burner design: Supports more even heat coverage from edge to edge across the griddle plate.
  • 38 MJ gas output: Delivers strong heat for faster preheating and confident high-temperature cooking.
  • Over 260 °C maximum temperature: Reaches searing heat for browning burgers, steaks and stir-fry ingredients.
  • Freestanding design: Suits fixed outdoor cooking zones without needing a built-in installation.
  • Mid-shelf storage: Keeps utensils, ingredients or cookware close by while you cook.

Q: Does this Weber griddle run on natural gas or LPG?

A: No. Weber Slate 3 Burner Griddle 30 is set up for LPG and includes a hose and regulator for that gas type. A natural gas connection is not listed for this model, so buyers wanting plumbed gas should not assume it will convert.

Q: Is this a flat-top griddle or a standard grill?

A: This model is a flat-top griddle with a pre-seasoned carbon steel cooktop, not a barbecue with open cooking grates. It suits foods like burgers, eggs and stir-fry ingredients, but it will not give the same grill-mark finish as grate cooking.

Q: Can the three burners create separate heat zones while cooking?

A: Yes. Weber Slate 3 Burner Griddle 30 has three burners, so different parts of the plate can be run hotter or lower for mixed cooking. The surface still stays continuous, so oil and juices can move across the plate more than on separated grill sections.

Q: Will the Weber Slate 30 fit a smaller outdoor area?

A: It depends on the space. Weber Slate 3 Burner Griddle 30 is a freestanding unit measuring 1800mm wide and 595mm deep, so it suits a medium to larger patio better than a tight balcony or narrow walkway where clearance is limited.

Q: What storage or prep space is built into this griddle?

A: This model includes a mid-shelf for keeping utensils, plates or ingredients close by during cooking. Optional Weber Works accessories are sold separately, so extra storage and prep options are not all included in the standard box.

Q: How easy is the carbon steel plate to clean?

A: The pre-seasoned carbon steel surface is generally straightforward to scrape and wipe down after cooking. It still needs regular care like clearing residue and maintaining the seasoned finish, because it is not a disposable liner or a dishwasher-safe plate.
