How do I make my gas grill burn hotter?

Like many people, some of us have conflicted feelings about the liquid propane grill. It’s handy, but only an imperfect substitute for high-temperature grilling over real charcoal. The cart grills many of us have cook like glorified butane burners: The grill marks are never as thick and black as you want them, and there’s no ambient smoke to flavor the food, unless you classify grease flareups as “smoke.”

Then we got some advice from the experts.

“Top Chef” veteran and former Juhu Beach Club and Navi Kitchen owner Preeti Mistry told us to get over it. They showed us how, with just a few expanding grates and a bag of lava rocks, they managed to hack their Weber propane barbecue to throw out as much heat as if it burned mesquite, a steady 500 degrees Fahrenheit or more. That means browned, deliciously crusty, juicy meats.

We had to see it for ourselves, so on a sunny afternoon in the chef’s Oakland backyard, Mistry gave us a demo. The hack yielded a fantastic piece of grilled hanger steak seasoned with chaat spices. Not identical to a steak grilled over charcoal, but Mistry did manage to boost the grill’s heat and—more important—kept it high, even through repeated lid liftings. Not a perfect solution to the gas-grill dilemma, but a worthwhile enhancement, and worth bringing back to light for the 2020 grilling season.

Here’s what you need:

  • Char-Broil Lava Rocks, 6 pounds for $16.51 on Amazon. Buy Now

1. Gather your equipment. You’ll need expandable grill grates to cover your barbecue’s burner well and enough lava rocks to form a tightly packed single layer on top of those grates.

2. Remove the cooking grates from your grill and cover the burner well with the expandable grates you’ve purchased.

3. Cover the grates with a tightly packed layer of lava rocks.

4. Replace the cooking grates and crank the burners as usual. Keep your grill’s lid closed while it heats.

5. Allow about 20 minutes for the temperature inside your grill to reach 500 degrees Fahrenheit or higher. The lava rocks will retain heat, so the temperature won’t plunge when you lift the lid. After several uses, the rocks will eventually get coated in rendered fat—flip them over when you need to. You’ll probably need to replace the lava rocks every few months, depending on how often you grill.

If you need to make your gas BBQ hotter without causing any damage to your food, home, yard, or yourself, you should use caution and follow some specific guidelines. It is also important to note your food will cook more quickly when making the grill hotter so you may need to adjust your timing to avoid overcooking or burning your food.

There are several things you can do to make sure your grill burns hotter and more efficient. By implementing these tips and maintaining your barbecue grill, you will be able to get the results you need.

1. Use Grill Bricks

Pile some grill bricks around the gas tube in your grill, to make your barbecue hotter. This works because the bricks will conduct the heat from the gas and will add heat to the cooking process, allowing you to grill your food faster or create higher temps. Do not pile the bricks high. Instead use only a single layer to make sure you cook your food evenly.

2. Maintain Your Grill

How do I make my gas grill burn hotter?

It is very important to maintain your gas grill. Cleaning it after each use will not only prevent fires from starting from dried up grease or food left over, it will also keep the way clear for the gas heat. It is easy to scrub off burnt oil and food while the grill is still warm. It is important that you are careful so that you do not burn yourself.

Also make sure that you have enough gas for grilling. If you are running low on gas, you may not be getting the amount of heat you need to keep the grill hot.

3. Turn Up the Heat

If your grill is clean, you can turn up the heat either by applying more gas to the flame or by using knobs and switches on your grill. Read the user's manual for your grill to find the right temperature you should use for each kind and cut of meat. Vegetables should be cooked at lower temperatures, so make sure you turn down the heat before applying those. You may need to practice a little with extra food until you know the right temperatures.

4. Allow the Grill to Heat Up Before Cooking

Make sure that you allow the grill to fully heat up before you cook your food. Not only will this allow your grill to become hotter, but you will be able to make sure that your food is cooked evenly and correctly. It will usually take 15 to 20 minutes for a grill to get hot, so ignite it while you whip up your favorite grilling recipe.

5. Wrap Food in Tin Foil

You can use tin foil to help your food get hotter. As the gas heat rises, it will conduct through the foil and get your food hotter faster.

Remember that a hotter grill can lead to a burnt dinner so you will want to closely monitor it as you cook.

Why is my gas grill not hot enough?

If you're experiencing low flame and low temperatures, start by resetting your grill's gas regulator. All gas grills have a propane regulator that controls the flow of gas from the propane tank to the grill, and this regulator is one of the most common reasons why a bbq is not getting hot enough.

Why is my grill only heats to 300?

If you do activate the gas regulator safety device, the grill will only reach temperatures between 250 and 300F even with all burners on the high setting. To reset the gas regulator safety device: Open the grill lid.

Does putting the top on the grill make it hotter?

Unlike ovens and gas grills that lose heat when the lid is opened, the opposite happens with charcoal grills. Opening the lid feeds extra oxygen to the coals, which causes them to burn even hotter and ups the potential for burning food.
