best smoker box for gas grill

Want to turn your gas grill into a smoker? Well, for that, my friends, you need a smoker box for your gas grill.

We all enjoy the advantages of propane and gas BBQ grills. Simply turn a knob, push a button, and fire! You’ve got flames and are ready to cook. Propane grills are clean, easy to use, and sometimes safer than charcoal grills.

However, gas and propane BBQ grills are easy to operate and are convenient. However, one significant disadvantage with gas grills is that you don’t get the smokey wood flavors that you get from charcoal or pellet grills. Well, there is a way to fix this. All you need is to add a smoker box to your grill. Using smoker boxes is straightforward, and in this article, we will help you find the right one for you.

Best smoker box for gas grills based on our research

1. The Char Broil Cast Iron Box

Char Broil vast iron smoker box

The Char Broil wood chip box is built out of cast iron, which means it will take longer to heat up and burn the chips but can stay hot for longer periods of time. 

Being built out of durable cast iron means it can withstand higher cooking temperatures than some of its stainless-built competitors. This box is large and has a well-vented lid, which should produce contact smoke during the cook. This box is heavy, feels solid, and is tough.

However, it is essential to remember that this box will require some maintenance to preserve its finish, coating, and stay rust-free. Char Broil recommends seasoning the box by applying a coat of cooking oil before using the box. This is a bit of extra maintenance but will keep this box going for a long time. 

Applying the “seasoning” process after the first couple of times using the product will prevent rust. Iron items do not like moisture, so do not pour pure water on a hot smoker box or leave it exposed to the elements.

Cave Tools is a relatively new company, founded in 2013. Cave Tools started as a small company and has designed and developed its products based on customer feedback. Cave Tools might be the youngest BBQ tool company in this review, but they sure are trying to earn your business. The first and most noticeable thing about this box is its thicker stainless steel build. 

Cave Tools states that they use 430-grade stainless steel, which is about twenty-five percent thicker than other brands’ stainless steel. The ticker steel should prevent warping, although if you put any of these boxes in your Green Egg and crank up the heat to 800 degrees, yes, they will warp.

What is a Smoker Box?

A smoker box is a small metal container shaped like a box and is used to burn wood chips to generate smoke, which infuses a smoky flavor to foods when grilled on gas grills or propane grills. It can also be used on charcoal grills and even on smokers. 

Smoke boxes are easy to use; simply fill the box with your favorite wood chips flavor or pellet and set the smokebox on top of the grill’s grates or top of the gas burners. Smoke boxes are an ingenious BBQ device, yet the most straightforward way of turning any gas, propane, or electric grill into a practical smoker.

A smoke box for gas grill applications can be found in different sizes and shapes, but the concept and how they work are the same.

How to use a smoker box in Your Gas Grill

Using smoke boxes in a gas grill is not rocket science; really, it isn’t. Smoke boxes are the simplest grill accessory you will ever own. Start by choosing the right wood chips for the meat you are cooking. 

Fill the container with wood chips or pellets and preheat your grill with the smoker box in it. This will allow the box to get hot enough to start burning the wood chips. 

Once you start seeing a bit of smoke coming out of the box, set the grill back to the desired cooking temperature, and put the meat in the grill. It is worth mentioning that you can also use these smoke boxes in charcoal grills to add an extra smokey flavor to your meats.

Do not preheat these boxes to high temperatures as you will damage them. When exposed to high temperatures, even the high quality boxes can be ruined. These boxes are meant to be used at smoking temperatures. Be patient! Enjoy the smoking process.

What to Consider When Choosing A Smoke box

Most smoke boxes have a similar look and design, but one must consider a few factors when choosing a smoker wood box.

Smoker box features like lid configuration, ventilation vents, and construction materials play significant roles when buying a smoker box for gas or propane grills. Let’s go over these factors and help you find the right box for you.

smoke boxes shapes illustration

Box Shape

There are two common shapes of smoke boxes, flat boxes and v-shape boxes. Flat or square smoke boxes can fit in just about any grill, although you still need to check and make sure they can fit between the burners and the grill grates, or at the very least rest on top of the grill’s cooking grates.

V-shaped smoke boxes are specially designed to fit in v-shaped burner heat covers, also called heat reflectors or flavoring bars. Many gas and propane grills use v-shape heat covers to distribute heat across the grill’s cooking surface evenly. The v-shape pockets make it an excellent anchor for these v-shaped smoker boxes. 

However, your grill must have “V” style burner heat covers to use these smoke boxes.

Box Size and wood chip capacity

You want the smoker box to be large enough to allow for a reasonable amount of wood chips; otherwise, it won’t smoke for long periods of time and will need constant refilling.

The box size and wood chip capacity will directly impact the amount of smoke it will generate and how long it will effectively produce smoke. Smaller smoke boxes will only hold small amounts of wood chips or smoking pellets, producing smoke for shorter periods and requiring frequent refilling.

On the plus side, smaller smoke boxes heat up faster and start making smoke quicker.

While wood chip capacity may not be an issue when grilling small cuts like pork chops or steaks, it becomes a problem when smoking a brisket or pork shoulder.

Bigger smoker boxes can hold more wood chips or pellets, produce large amounts of smoke and keep producing smoke for longer periods. Larger wood chip boxes will take longer to ignite the wood chips, but if you are doing long cooks or cooking large amounts of food, consider bigger smoker boxes with a good wood chip capacity.

Construction Materials: 

Materials Used and Durability

You’ll want to pay close attention to the materials used to build the smoker box. Some materials are prone to corrosion, and when exposed to continuous heat, they will start to corrode, warp, discolor, and break apart. 

Remember, these boxes will rest directly above your grill’s heat source; they will get used and abused, plus you need to get enough fire to radiate heat to the wood chips inside the box.

Some steel smoker boxes models are built using high-grade, durable stainless steel, which can be pretty resistant to heat damage, while others are made using cast iron. 

Staines Steel Grade

Stainless steel is an excellent material for building grills, smoker boxes, and just about any major cooking appliance. However, it is essential to understand the difference between various grades of steel. Different steel grades will affect the quality, durability, and heat tolerance of the product. The higher the steel grade, the better the product will be. 

Another common material used to build wood chip boxes for gas and propane grills is cast iron. Iron boxes can take longer to heat up but do a better job of absorbing and retaining heat, which helps during long cooks. By absorbing and keeping heat better, these boxes can start generating smoke quicker between wood refills. 

Cast iron smoker boxes do a great job of transferring heat to the wood and keeping a more steady smoke flow during long cooks. If properly maintained, these boxes can last for years.

Easy Clean

These boxes usually sit right under the food you are cooking, and all the fat and grease from your food will land right on your smoker box. After a long cook, your box can look quite dirty; thus, consider something easy to clean up. Some boxes, such as cast iron boxes, will require more maintenance, such as oil coating, to keep their finish neat and rust-free.

Good Lid Design

It’s important that the box’s lid fits snugly but is also easy to open. Some smoke box lids are hinged, making them easier to tilt open, while others are free, requiring a bit more precision and care when opening.

Also, the lid of the box will have something to do with the smoke output. A lid with a few holes might retain heat better, but a box with more holes can have a better smoke output. The best smoker boxes will have an easy-to-use lid design.

If the lid doesn’t create a good seal around the box and too much oxygen flows through the box, the wood chips can ignite into flames. Flame smoke is not good, and your wood chips won’t last more than a few minutes.

Smoke flow is important since too much smoke will drastically alter the flavor of your meal, and too little smoke flow will have minimal effect throughout the cooking process and add little to no smoky flavor.

Using a Smoker Box on Your Gas Grill

Smoke or wood chip boxes are simple to use, but you achieve amazing smoky flavors by using one.

Are these boxes worth it?

We all enjoy the ease of use and simplicity that gas and propane grills offer. A smoker box for gas grill use is absolutely worth it if you want to add a smoky flavor to your food. But the bottom line is that gas grills burn propane or natural gas, which doesn’t generate smoke or wood flavors like charcoal or burning wood.

This is why these smoke boxes are useful. By using a smoker box, you can turn your gas grill or even charcoal grill into an amazing smoker and add amazing smoke wood flavors to your food.

If you don’t want to spend the money on buying a smoker, these boxes will get you pretty close to the real deal.

One Last Word

We all like the taste of smoked BBQ, and smoking meats can be a lot of fun. However, not all of us own smoker grills to smoke the perfect rack of ribs or brisket. 

Maybe you just want to add more flavor to your pork chops or steaks. Well, these boxes will do the job. If you simply throw wood chips on top of the burners, you will burn the chips and potentially damage your grill’s burners. 

This inexpensive gadget is a great way to improve your grilling and impress your friends and family. The best smoker boxes will turn your grill into a smoker.

Always remember to enjoy the process.
