How does a smoker box work?

These metal boxes may look pretty simple, but the fact is they are an ingenious way to transform a regular natural or propane gas grill into a completely functional smoker.

They are affordable and easy-to-use tools suitable for beginner smoking enthusiasts as well as for those who already own a gas grill and want to upgrade it into a more versatile appliance.

The smoker box is made of steel or cast iron and has a lid with holes that work as air vents.

The box is filled with the wood chips of your choice, and they are lit until they start to smoke. Once the wood begins smoldering, the lid can be closed and the box placed on the grate in the middle of the chamber.

This will allow the smoke to start filling the chamber of the grill and to begin the smoking and flavoring of the food which is being cooked.

They can work with almost all types of gas grills, and some can be used in charcoal grills as well.

They are a much more affordable and space-saving alternative to buying a separate smoker.

Features to look for when choosing the most suitable smoker box


Most smoker boxes for gas grills are quite similar, but you will need to keep several features in mind in order to ensure that you are buying the best one for your needs.

First of all, you are advised to measure the distance between the grill grates and the burners of your grill, and then choose a box that can easily fit in that space.

Then, you must decide whether you want a flat box or a v-shaped one. The v-shaped smokers are more likely to fit into the slot between the burners of most grills, while the flat ones differ in width and depth and may not be suitable for all grill types and sizes.

On the other hand, larger boxes can fit more wood chips which means that you won’t need to keep adding more and more wood to the box during a long, low, and slow cook.

After you have decided on the shape and size of your smoker box, you should consider what type of material you prefer.

The best options that can withstand high temperatures without warping and hold the heat for longer are cast iron and stainless steel.

Buying a smoker box made of cheap metal may lead to quick warping, rusting, and destruction of the box.

Last but not least, consider the type of lid you want.

The lids with hinges are easier to access, open and close, which is crucial when the box is scorching hot, and you are working with thick grill gloves.

Using the smoker box with a gas grill

Like with any other type of cooking, the results depend on the proper preparation of the ingredients and tools.

In order to get the best results when using a smoker box, it is recommended that you pre-soak the wood chips which you will be using. This should be done about half an hour before smoking. The pre-soaking not only helps the generating of more smoke but will also prevent the wood chips from burning out very quickly.

As for the wood chips you should use – this depends on your personal preferences and on the recipe and meat you are smoking.

A rule of thumb is that hickory and oak are more suitable for red meats, while mesquite is a better choice for smoking fish.

Once you have selected the wood chips and have pre-soaked them, you can add them to the smoker box.

Fill the box up to just over the halfway line. Place it in the center of the grill chamber in between the grill grates and deflector bars.

Turn on the grill to a high temperature to preheat the smoker box. Once the smoke starts coming out of the vent holes on the lid, you can turn down the temperature to the desired level and start smoking.

It would be best if you refrained from opening the door or lid of the grill unless it is absolutely necessary. This will help keep the heat and smoke inside and at consistent levels.

Then proceed with the smoking according to the specific recipe for meat smoking you have selected.
