Lava rocks are not necessary for a gas grill, but they can help to distribute heat more evenly. The rocks also absorb and radiate back some of the heat, which can make your food cook more evenly.

Setup Nexgrill Gas Grill to Use Lava Rocks

If you’re using a gas grill, you might be wondering if you need to use lava rocks. The answer is yes! Lava rocks help to distribute the heat evenly across the grilling surface and can also help to prevent flare-ups.

Plus, they just look really cool.

Benefits of Using Lava Rocks in Gas Grill

If you’re looking for a way to add some flavor to your grilled foods, consider using lava rocks. Lava rocks are heated to high temperatures and then placed on the grill, where they release their flavorful smoke. This can be a great way to add some extra flavor to your grilled meats and vegetables.

Lava rocks can be found at most hardware or home improvement stores. They’re usually inexpensive, so they won’t break the bank. And, since they last for years, you’ll get plenty of use out of them.

To use lava rocks, simply preheat your grill to high heat. Then, place the lava rocks on the grill grates and cook as usual. The flavored smoke will infuse your food with delicious flavor.

Just be sure to brush the grill grates clean after cooking so that the next time you use them, there’s no risk of contamination.

Why Don’T Gas Grills Use Lava Rocks Anymore

In the past, lava rocks were a popular way to heat up gas grills. The rocks would be placed in the bottom of the grill and then heated up until they were red hot. This would then radiate heat upwards, cooking the food on the grill.

However, lava rocks are no longer used for this purpose for a few reasons. First, they can be difficult to clean. Lava rock is very porous and can absorb grease and other residue from cooking.

This can make it hard to get the grill clean and can also lead to bacteria build-up. Second, lava rocks can break down over time and become sharp pieces that can puncture the gas tank of your grill. When this happens, it can cause a dangerous gas leak.

Finally, lava rocks can be expensive compared to other options like ceramic briquettes or stainless steel heat plates. For these reasons, most manufacturers have stopped using lava rocks in their grills and have switched to other methods of heating.

Ceramic Briquettes for Gas Grill

If you’re a fan of cooking with gas, then you know that one of the most important things for getting great results is to use the right type of briquettes. And when it comes to ceramic briquettes, they are definitely one of the best options out there. Here’s everything you need to know about them:

What are ceramic briquettes? Ceramic briquettes are made from clay that has been fired in a kiln. They have a high heat capacity and conductivity, which makes them ideal for use in gas grills.

How do they work? Ceramic briquettes work by evenly distributing heat across the entire grilling surface. This ensures that your food will cook evenly and prevent hotspots from forming.

Additionally, the pores in the briquettes help to vaporize juices and fats, which adds flavor and prevents flare-ups. Why are they better than other types of briquettes? Other types of briquettes (such as lava rock or charcoal) can actually absorb moisture from your food, leading to dryness.

Ceramic briquettes, on the other hand, don’t absorb moisture – so your food will stay juicier and more flavorful. Additionally, since they don’t absorb flavors, they won’t impart any unwanted tastes onto your food like some other types of briquettes can.

Lava Rocks for Gas Grill

If you’re looking to add some flavor to your gas grill, consider using lava rocks. Lava rocks are made from igneous rock that has been cooled and solidified. When heated, they release their trapped gases, which can give your food a unique flavor.

Lava rocks can be found at most hardware or home improvement stores. Be sure to get ones that are specifically for use with gas grills – don’t use regular rocks, as they can explode when heated! To use, simply preheat your grill with the lava rocks inside.

Once it’s hot, remove the rocks and cook your food as usual. One thing to keep in mind is that lava rocks will absorb grease and other liquids, so you’ll want to clean them regularly. A good scrubbing with soapy water should do the trick.

And because they’re porous, they can also harbor bacteria if not cleaned properly – so be sure to clean them often!

Can I Use Lava Rocks in My Weber Gas Grill

If you’re a fan of cooking with gas, you may be wondering if you can use lava rocks in your Weber gas grill. The short answer is yes! Lava rocks can be used in gas grills to help distribute heat evenly and create those signature grill marks that we all love.

Here’s a quick guide on how to use lava rocks in your Weber gas grill: 1. Preheat your grill on high for 15 minutes with the lid closed. This will give the lava rocks time to heat up.

2. Spread an even layer of lava rocks over the entire grilling surface. 3. Turn off any burner vents or igniters that are directly underneath where you’ll be placing food on the grill. This will prevent them from getting too hot and causing flare-ups.

4. Grill your food as usual, being careful not to overcrowd the grill so that the heat can circulate evenly around each piece of food. Keep an eye on temperature gauges to ensure that your food is cooking through properly without burning on the outside.

Should I Put Lava Rocks on My Gas Grill?

If you’re wondering whether or not you should put lava rocks on your gas grill, the answer is yes! Lava rocks can help improve the performance of your grill and make it last longer. Here’s what you need to know about using lava rocks on your gas grill.

Lava rocks are made from igneous rock that has been melted and cooled. They’re found all over the world, but most commonly in volcanic regions. When used on a gas grill, they help to evenly distribute heat and prevent flare-ups.

One of the benefits of using lava rocks is that they don’t retain moisture like other materials such as briquettes or wood chips. This means that they won’t produce smoke when they come into contact with flames, making them ideal for grilling. Another benefit of lava rocks is that they don’t break down over time like other materials can.

This means that you won’t have to replace them as often, saving you money in the long run. To use lava rocks on your grill, simply place them in the bottom of the grill before lighting it up. You’ll want to make sure that they’re evenly distributed so that they can work properly.

Does a Gas Grill Need Briquettes?

No, a gas grill does not need briquettes. Briquettes are commonly used in charcoal grills to help evenly distribute the heat, but gas grills already have a built-in heat diffuser. Additionally, briquettes can add an unpleasant flavor to food that is cooked on them.

Do Weber Gas Grills Use Lava Rocks?

Weber gas grills use lava rocks to help evenly distribute heat. The rocks are placed over the burner and radiate heat up and out, providing even cooking temperatures across the entire grill. The rocks also help create a barrier between the direct flame and your food, so you don’t have to worry about flare-ups.

What are the Rocks for in a Gas Grill?

Most gas grills have a layer of rocks or lava stones underneath the cooking grate. The purpose of these rocks is twofold. First, they act as a heat diffuser, evening out the heat so that your food doesn’t get charred on one side and raw on the other.

Second, they help to vaporize any juices or fats that drip down from the food above, preventing them from causing flare-ups.


Most gas grills come with a layer of lava rocks resting on the burner. The purpose of these rocks is to evenly distribute heat and prevent flare-ups. Many grillers, however, question whether they actually need lava rocks in their grill.

The answer is: it depends. If you frequently experience flare-ups or uneven heat distribution, then you may benefit from using lava rocks. However, if you don’t have any problems with your current setup, then you probably don’t need to bother with them.
