    CosmoGrill Platinum 6+2: rotisserie and side sear zone

    At 27.7 kW combined, it has the highest stated total output in this guide.

    Check price on AmazonAffiliate link

A side burner turns a gas BBQ into a small outdoor kitchen. You can warm a sauce, boil corn or fry onions in a pan while the main grate handles the meat, so you are not running back to the hob indoors. Some makers fit a plain hob ring; others fit an infrared sear zone that gets far hotter and is better for a crust on steak than for a pan of beans. What separates a good pick is the size of the main grate, how many main burners you get for zoned cooking, whether the side burner output is stated, and how solid the cart is. This guide compares six gas BBQs with three to six main burners plus a side burner, from Weber, CosmoGrill, TOV and Cook'in Garden. Every figure comes from the product listing, and where a listing leaves something out, such as the side burner power or the grate size, we say so.

No. 1 · CosmoGrill

CosmoGrill Platinum 4+2: 4 kW infrared side searer

A stainless steel four burner gas BBQ with a 4 kW ceramic infrared side searer, a 3.2 kW back burner and a glass viewing window in the hood. Suits a family garden where steaks get seared on the side.

In its favour

  • The listing states every burner output, including the 4 kW ceramic side searer, so you know what you are buying.
  • A 37 mbar propane regulator and hose are included, so you only need a gas bottle to start.
  • A tempered glass window in the hood lets you check food without lifting the lid.

Good to know

  • The side unit is an infrared searer, not a hob ring, so it suits steak better than a pan of sauce.
  • At 140 cm wide and 43 kg it needs a fair amount of patio space.
