How to choose the best gas BBQ

Gas barbecues come in all manner of shapes and sizes, with two burner units often sitting along side the more serious-looking six burner BBQs. This means that there are a few factors you'll need to consider before making a decision..

Single or multiple burners?
Gas BBQs with multiple burners are the best. You can seal your food on the heat, then turn half the burners off, close the lid and allow your food to cook super slowly off the direct heat. The Weber Genesis II LX S-640 is the king of all BBQs, with 6 burners for careful cooking control and flavouriser bars to help circulate smoke produced from dripping meat juices and marinades. 

The best material for a gas burner is stainless steel – sturdier than aluminium, but more portable (and easier to clean) than cast iron. 

Extra features?
The best gas barbecues will have some kind of food prep area – pull-out side shelves, for example – and perhaps additional cooking features such as a roasting basket. Look out for technologies that address the potential lack of flavour from a gas bbqs - the best should compensate for the lack of charcoal with structural features that maximise the smoky infusion effect.

How much to spend on a gas BBQ

As we now know, gas BBQs feature a wide range of gadgets and burners, which all come in various sizes. Depending on which make and model of barbecues you are drawn to, you will ultimately see differences in price.

There are big price differences amongst the well-known brands and those available in supermarkets, and also notable differences in the built quality. Plus, the more burner and more special features you opt for, will also rack up the amount you spend.

And beyond the initial purchase of the BBQ, there will be further costs to use and maintain it such as replenishing the fuel; charcoal can often be picked up from DIY stores, garages or supermarkets, and gas canisters will need to be refilled or replaced at DIY stores.

What is the best gas BBQ?

So, let's recap... if you want a gas BBQ that will last a lifetime, and money is no object, you really can't do much better than the spectacular Weber Genesis II E-310. This gas barbecue is approaching an outdoor kitchen in its sophistication. Want something much more affordable? Try the CosmoGrill 4+1 Gas Burner Garden BBQ.
