The bottom of the box doesn’t have any holes in it, to keep the wood chips smoldering instead of catching on fire.

  • Weight: 1.76 pounds

More features: holds 7 pounds of wood chunks that last for up to 3 hours

The DKS Smoker Cooker Box for Grill is a cube-shaped smoker box, which gives it a larger storage capacity. This makes it a great choice for those who are looking for a smoker box that they can use wood chunks with, not just wood chips. In fact, this smoker box can hold up to an incredible 7 pounds of wood that can last up to three hours for excellent smoking sessions. It’s built to turn your grill into a full smoker, which means you don’t need to use charcoal, electricity, or propane to generate the smoke because it is not relying on the heat already generated on your grill to add a smoky flavor. It uses the wood chunks to heat the grill instead, though some users stated that they had trouble maintaining the needed temperature with only the wood chunks and had to rely on propane for an assist. It can also be used to cold smoke as well, though DKS does offer a specific cold smoker model for those more interested in cold smoking. It does not have a hinged lid, though, which means adding wood chunks to the middle of a smoking session can be a bit more difficult, though its 3-hour smoke time alleviates this problem in a lot of cases.

  • Turns grill into an actual smoker
  • Holds 7 pounds of wood chunks
  • 3-hour smoke time

  • Dimensions: 7.1 x 4.2 x 2.4 inches
  • Weight: 2.99 pounds

More features: can be used on flame deflector bars or on cooking grates

The Charcoal Companion CC4133 Gas Grill V Box Cast Iron Smoker is a V-shaped smoker that fits in between the deflectors of a gas grill, or on the grates of a charcoal grill. Though users will want to make sure to double-check the measurements of their grill compared to this smoker box to make sure it will fit with their grill, as not all v-shaped boxes will fit with every grill. Though many weber grill owners stated this box fit perfectly for them making this a great cast iron smoker box for gas grills. This box is made of cast iron, which means you will absolutely never have to worry about it warping. The cast iron, though, creates a heavier weight of almost 3 pounds. And cast iron can rust easily, so users will need to make sure to properly take care of the box and never let water or moisture rest on the surface for any length of time. Cast iron can deal with high heat for a long period, but it can also take a while to fully heat so that’s something to keep in mind as well. Some users stated that it doesn’t do a good enough job producing smoke because the cast iron is too thick. It’s also on the smaller side and therefore doesn’t hold a lot of chips, so for full grill smoking, you may need to purchase more than one.

What are its best features?

  • Cast iron won’t warp
  • Heavy-duty construction

What could be improved?

  • Small dimensions
  • Not a lot of smoke
Features
  • Material: stainless steel
  • Dimensions: 12.5 x 3.3 x 2.5 inches
  • Weight: 1.59 pounds

More features: wavy smoke outlets; can be placed between the flame deflector bars of gas grills or on cooking grates

The Skyflame Universal Stainless Steel Wood Chip Smoker Box with Wavy Smoke Outlet is a W shaped smoker box, which means it balances on top of a deflector bar or a grate, though it would not be a good choice for grills without those options, or thinly spaced grates, so make sure you take in the measurements of the box as it compares to your personal grill. It has a hinged lid for easily adding more wood chips during longer smoking sessions, and its thicker stainless steel means it should stand up to higher temperatures without warping. It uses a wave smoke outlet design, which concentrates the smoke and creates a large smoked area for the food above, creating a more permeable smoky flavor, though a few users stated that it didn’t give as much of a smoky flavor as they were hoping.

It weighs over 1.5 pounds, though, which is on the heavy side of stainless-steel smoker boxes. It’s quick to heat up because of how it rests right on the deflector, though some users stated this could cause the woodchips to burn during longer grill sessions so it may need to be monitored to prevent the chips from catching fire.

What are our favorite features?

  • W shape is handy
  • Wavy smoke outlet design

What could be better?

  • Will not fit in all grills
  • Milder smoky flavor

Things to Consider

After considering ten of the smoking boxes, we think are the best on the market, it makes sense to discuss the features you need to look out for in a smoking box. So, we gathered the most relevant of them below.

Type: V-shaped or regular box?

10 Best Smoker Boxes for a Gas Grill to Add That Delicious Smoky Flavor to Your Meals

There are a variety of different smoke box shapes to consider when looking for the best smoker box for you and your needs, but the two most common ones are regular, rectangular boxed shaped ones and boxes that are shaped like a V. V-shaped ones are great because they sit close to the heat source, but the biggest downfall is that they don’t fit with every grill, so you will need to check the measurements of your grill to make sure it will work for you.

Material: stainless steel or cast iron?

The main two material options for smoker boxes are stainless steel or cast iron. They both have their pros and cons. Stainless steel won’t rust (as long as it’s true stainless steel) but tends to warp at high temperatures. Cast iron will never warp or change shape, but it’s prone to easy rusting if not taken care of correctly. For a cast iron option, check out the v-shaped Charcoal Companion CC4133 Gas Grill V Box Cast Iron Smoker, and for a stainless-steel box that had no complaints of warping look at the Silverius Pro BBQ Smoker Box or the Kaluns BBQ Smoker Box for Wood Chips.

Durability

Durability is an important consideration when looking at smoker boxes, because if they don’t last long, or if they break easily, then there’s no point in spending the money on them. In general, cast iron will have the greatest durability because iron is heavy-duty and long-lasting as long as they’re well taken care of, but there are some good stainless-steel options, too, that are sturdy and well made, such as the Kaluns BBQ Smoker Box for Wood Chips.

Dimensions and capacity

10 Best Smoker Boxes for a Gas Grill to Add That Delicious Smoky Flavor to Your Meals

When looking at smoker boxes, make sure you check out the dimensions and capacity. The dimensions will make sure that the box you’re interested in will actually fit in your personal grill, and the capacity will tell you how much wood the box can hold, which will allow for longer smoking sessions. For the smoker box with the largest capacity, check out the DKS Smoker Cooker Box for Grill which holds an amazing 7 pounds of wood chunks for 3 hours of smoking.

Lid

Lids on smoker boxes are either hinged or not and there are pros and cons to each version. Hinged lids make it easy to add more chips in the middle of a smoking session as you can just flip the lid open, then shut it. But hinged lids can be problematic if your box is prone to warping. Unhinged lids can be hard to take on and off in the middle of a smoke section, but they also allow the user to choose lid placement, too, allowing more choices of smoke level, such as in the case of the Silverius Pro BBQ Smoker Box.

Where a box can be placed

Where a box can be placed often depends on its shape and size. Many of them are designed to go under the grill grates or even directly on top of the flame or charcoal in charcoal grills. Some have specialized shapes, though, which limit where they can go, such as the W shape of the Skyflame Universal Stainless-Steel Wood Chip Smoker Box with Wavy Smoke Outlet.

How to clean and maintain your smoker box?

Cleaning and maintain your smoker box can help extend the life of your box as well as improve its durability. Follow these tips to maintaining your grill box:

  • Wipe any grease off the top of your grill box when not in use
  • Empty out all ashes from the smoker box once you’ve finished a smoke session
  • For cast-iron boxes, make sure to dry it thoroughly as even a small amount of moisture can lead to rusting
  • If your smoker box is painted, make sure the paint is burned away before using it to flavor your food

FAQ

Where you place your box depends on the shape of the box and the type of grill you’re using. For gas grills, most smoker boxes can sit right on top of your deflectors or flavorizer bars.

If you’re just starting out with smoking, it may be a good idea to try it using foil first, to make sure you enjoy the flavor and the effort of smoking your food. But in order to get the best smoking results, it’s a good idea to upgrade to a smoking box when you can.

V-shaped boxes are designed to sit in between the deflectors or flavorizer bars whereas a rectangular box is designed to sit on top of the bars. Not all v-shaped ones will work with the dimensions of every grill, and some rectangular boxes may be too large to fit beneath your grill grates, so a v-shaped one may be the best choice.

It depends on the temperature of your grill and the material of your box. Cast iron needs longer to heat up, but once it does it can go for hours. Stainless steel will heat up much quicker but can still take between 10–15 minutes to generate smoke from your wood chips.

If you’re using stainless steel, chances are it will warp sooner or later, depending on how high the heat is that it’s exposed to. Cast iron will rarely warp, though it can easily rust.

These smoker boxes are designed to add smoke flavor to your food as opposed to actually smoking. Because you would need to regulate the temperature throughout the smoking process and many of these boxes are too small for longer smoking sessions. The exception being the DKS Smoker Cooker Box for Grill which is designed to turn your grill into an actual smoker.

Our Verdict

Smoker boxes are a great, convenient way to add smoky flavor to your food when grilling and if you’re shopping for a smoker box, chances are there’s a model that fits your needs.
