# Best large gas BBQs for family parties Source: https://charandsmoke.co.uk/best/best-large-gas-bbq-for-entertaining Publisher: Char and Smoke. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://charandsmoke.co.uk/how-we-pick Cooking for ten or more at a birthday or a summer party is a different job from a weeknight burger. You need a big primary area so the first batch is not cold before the last one is done, a warming rack to hold buns and cooked meat, and enough burners to run a hot searing zone beside a gentle zone for chicken. Extra burners help too: a side burner for beans or sauce, a sear burner for steaks, or a rear rotisserie burner on some models. Size has a cost in garden space and weight, so measure the patio first. This guide compares six large gas grills by burner layout, stated power in kW, cooking area, the extra burners and the storage each listing names. Where a listing leaves a figure out we say so, so you know what to check before ordering. ## Products ### 1.
