Getting a good smoker box is a fantastic way to turn your regular gas or propane grill into a fully fledged barbecue smoker.

They’re used to house wood chips, and are placed over your grills burners. Smoker boxes have holes across their top surface, which allow smoke to escape and impart flavor on your food.

If you’ve read any of my other posts on smoking meat then you know just how much I love the BBQ form.

Don’t get me wrong, I love my grilling, but there’s something special about smoking meat.

Smoker boxes give BBQ fans an easy and affordable way into the beautiful world of barbecue smoking.

They turn your regular gas grill into a smoking machine, and today I’m going to run through my top 7 picks for the best smoker boxes for gas grills.

The Best Smoker Box: Cave Tools

Cave Tools have been making high quality, specialist grilling equipment for years, so it stands to reason that this beauty sits at the top of my list.

It measures at three by nine inches, and can hold up to two cups of wood chips. This is more than enough to house a good amount of wood chips to turn your grill into a smoker.

The key to a good smoker box is to not dominate the grill, and this box from Cave Tools fits the bill perfectly.

It comfortably fits between the grates of most gas grills, and can even be used on charcoal grills. It has a lid that allows you to easily add new wood chips while you cook. This is really important because a smoker box needs to be topped up regularly during smoking.

Standard BBQ smokers are known for taking their time to heat up to reach target temperatures, but the beauty of a smoker box is that there’s nowhere near as much waiting around. In the case of the Cave Tools box, it only needs about 10 minutes before your wood chips are smoldering.

Runner-Up: Cave Tools Smoker Box Maximum Wood Chip Capacity

Not the first Cave Tools smoker in this list, but these guys really do know what they’re doing.

What I really like about this one is its smoking potential. Its size means that its smoke output is extremely impressive, and surpasses most of the other boxes on this list.

It’s a large box, which means that its wood chip capacity is excellent at three cups. This doesn’t just mean that you don’t have to replenish the fuel supply as much, but it also means that your smoking power output is far better.

Its dimensions make it wide but shallow. This helps keep heat distribution within your grill very even, reducing the risk of dreaded ‘hot spots’ (or indeed cold!) and helping to cook a greater area of food.

Its size does mean that it might be too big for some grills, so before buying it do make sure to check the size of your grill.

If your can grill can fit it, definitely get it.

This is a great option for people wanting to get as much bang for their buck out as possible. The only potential obstacle is it actually fitting in your grill.

#4. Charcoal Companion Stainless Steel V-Shape Smoker Box

Don’t be fooled by the name of this one – it actually suits gas grills perfectly.

One of the first things to strike you when you see this smoker box is it looks very sturdy. Made with heavy gauge stainless steel, it is built to last. It’s extremely durable and will be able to easily withstand the temperatures involved in BBQ smoking.

Made in a v-shape, it’s designed to sit perfectly in your gas grill, lying between your grill’s deflector bars and grill grates.

It’s quite large, measuring close to 14 inches in length. It’s designed to be wide enough to ensure even heat distribution and increased cooking capacity. However this length could be prohibitive to users with small grills, so be sure to measure up before buying it. If your grill is big enough to fit it then you’re onto a winner.

It has an easy-to-open lid on a hinge, making replenishing your wood chip supplies during smoking easy.

#6. Grillaholics Smoker Box

This box fits comfortably in almost any gas grill, and is deep enough to hold a good amount of wood chips.

The walls of the box are quite thin which has a couple of side effects. One is that it generates a lot of smoke. This is great for imparting a rich, thick smoky flavor on your food. Perfect at replicating the flavors of an authentic smoker.

The other consequence of this is that your wood chips will burn out faster, meaning you will need to replace them more frequently. This can be an inconvenience, but will also involve higher wood chip costs over time.

What is a smoker box?

These little metallic crates might not look like much on their own, but they’re a fantastic way in to the world of BBQ smoking for newbies and gas grill owners.

A smoker box is essentially a small steel box that houses wood chips. The chips are lit and brought to a smolder. Once they are smoldering the lid of the box is closed, and the holes and air vents on the lid allow smoke to flow into the chamber of your gas grill.

Because of how simple they are, they can be used with almost any gas grill, and can even be used with charcoal grills too.

This smoke flow makes them an easy and cost-effective way to get fantastic smokey flavors from your grill that you otherwise wouldn’t be able to.

How to choose your smoker box

What to look out for when choosing your smoker box

Shape & Size: Some smokers are flat in shape, while some are v-shaped. With flat boxes, not all grills can accommodate them well, while v-shaped boxes tend to be able to slot between your burner covers quite well.

The key thing to consider is the depth of the box. It needs to be able to fit between your burners and your grill grates. So be sure to measure this distance before buying your smoker box.

Material: While a smoker box is in essence a really simple tool, there is a big difference in cheaper and elite models. This difference can usually be found in the type of metal that they’re made of.

Stainless steel or cast iron is your best bet, as they will retain heat well while guarding the chips from overheating and burning out. Further to this, they’ll also be durable so will help to withstand being exposed to high cooking temperatures time and time again without rusting or falling apart.

How to use a smoker box

Like with any form of cooking, preparation is key. Start by pre-soaking your chosen wood chips about half an hour prior to smoking. This helps generate smoke, as well as stops the chips from burning out too quickly.

What flavor of wood chip you go for largely depends on what meat you are smoking. As a rough guide, oak or hickory goes great with red meats, while mesquite matches well with fish.

Once your chips are ready, start to transfer them to your box. Aim to fill it just over halfway.

The key thing is to place it so that it sits between your flame deflector bars and grill grates. It needs to be firmly still, and placed at the center of your grill’s chamber. Luckily, a lot of the best smoker boxes are v-shaped, which helps them stay in place securely.

Turn your grill on at high temperature and preheat the box. Different smokers and grills take different lengths of time to get going, so there is no hard and fast rule here. A good rule is  once you start seeing smoke coming from your box, dial down the heat to low and you’re good to go.

When cooking, be sure to keep the lid of your grill closed. This will keep the smoke condensed in your grill’s barrel, and help make your food rich in smoky, BBQ goodness.

Different meats take different lengths of time to cook, so for help make sure to check out my guide to meat smoking.
