✔️ Propane vs. Natural Gas: These are your two options to fire up a gas grill. We exclusively test propane grills for their ease of use, but natural grills are also popular picks.
- Propane comes in tanks that sit next to or inside the grill, making it portable since propane tanks come in a variety of sizes and some are small enough to travel with. It can provide a serious amount of heat quickly. Make sure to monitor the amount of gas left in the tank so that you don't run out in the middle of your cook-out!
- Natural gas runs through your home like any other utility, so you need to have an available gas line in order to hook up the grill. Once it's hooked up, you won't have to think about it again (although it means you can't move the grill). It has the advantages of being cheaper over time, especially if you grill frequently. You also don’t risk running out of gas mid-cook like you might with propane.
✔️ Grate material: The material of the grill grate — your cooking surface — determines how quickly it heats and stays hot, how easy it is to clean and maintain and whether or not food will stick to it. Most are made of stainless steel, cast iron or coated cast iron. No matter the material, keeping your grill grates clean and well-maintained will help it last longer and perform better (no stuck-on food).
- Stainless steel is light which makes it easy to handle when cleaning, and it's affordable. The material heats up quickly, but it doesn’t retain heat well and will corrode over time, causing food to stick to it.
- Cast iron may be heavy and needs to be maintained to stay non-stick and rust-free, but it retains heat well for great sear marks and is very durable.
- Coated cast iron grates with porcelain or enamel provide even better heat retention and protection against rusting. Just remember to keep metal grilling tools away, so that the coating doesn’t chip.
✔️ Number of burners: The number of burners on a gas grill dictates the cooking area and the kinds of grilling techniques that are available to you.
- Up to three burners are great for small families (a couple of steaks and a vegetable side) or gatherings (a dozen burgers).
- Three or four burners give you the versatility of creating heat zones, one of the biggest advantages of gas grills. The burner on one side can be on high for searing while the other side can be on low or off for slower cooking (you don’t want the outside of your chicken to burn while the inside is still raw).
- With any more burners, you can have an epic cookout for large gatherings and create even extra heat zones to cook multiple courses at once.
✔️ Heat output: You may have heard of BTU (British Thermal Units) levels advertised on gas grills. It basically measures the amount of heat output. The higher the BTUs, the more powerful the grill — but that doesn’t necessarily mean better. Instead, look at the maximum temperature and range the gas grill provides. If you like to smoke or grill foods that need to be cooked low and slow (briskets, pork shoulders or ribs), your gas grill should go down to 200ºF. For steaks, burgers or pizza, you want the gas grill to reach at least 500ºF.
