You can smoke food really well on a charcoal or gas grill, but if you love barbecue and make it often, there are a few reasons to invest in a dedicated smoker. Most good smokers can maintain lower temperatures than a grill can—from 225 to 250 degrees, the low-and-slow temperature range barbecue experts recommend for turning tough cuts of meat tender without drying them out. (On grills, smoking temperatures range from 275 to 325 degrees.) In addition, most smokers allow you to maintain temperatures more consistently and precisely than you can on a grill. Many also have larger fuel capacities (unlimited with electric models), so you won’t have to worry as much about running out of heat during long cooking times.
Smokers are generally categorized by the type of fuel they use: charcoal, gas, or electricity. On a broad scale, they all work similarly. The fuel provides the smoker with heat, turning it into a vented oven. You add wood chunks or chips directly on top of that fuel or contain them in metal pans suspended over the heat. The wood heats up, producing the smoke that is essential to barbecue flavor.
We smoked sides of salmon in all the smokers to see how well the models were able to maintain low temperatures for short periods and to see how the salmon's smoke flavor differed.
Each type of fuel has different advantages and disadvantages. To learn which smoker best fits your needs, read on.
Charcoal Smokers: Great Barbecue, a Little Work
Pros: Of the three types of smokers tested, charcoal smokers produced the best-tasting barbecue, hands down. No matter what we cooked, tasters unanimously preferred the food cooked in charcoal smokers; it was consistently deeper in flavor than food cooked in gas or electric smokers. It wasn’t just smoky, it tasted of the fire—rich and woodsy, with extra charred and caramelized notes.
Despite a slight difference in operating temperature, both of the charcoal smokers we tested made delicious, good-looking chicken.
This is because charcoal makes more—and better—smoke than gas or electricity does. It burns wood at hotter temperatures, creating a greater volume of smoke with a more varied, aromatic array of flavor molecules. And as author and barbecue expert Meathead Goldwyn hypothesizes, charcoal itself may serve as an additional source of flavor, as it contains complex organic molecules that contribute new aromas when burned.
Charcoal smokers such as the one on the right not only make different smoke than gas and electric models—they make more of it, too.
Another plus: Charcoal smokers are usually simple metal vessels, so they’re easy to assemble and maintain. They also have fewer parts that can break or get damaged.
Tasters unanimously preferred the flavor of ribs cooked on charcoal smokers.
Cons: As a fuel source, charcoal is messy and fussier to use. With many charcoal models, you’ll need to adjust the air intake vents periodically to maintain a low heat. Depending on the length of your cooking time and the weather, you may need to configure your charcoal and wood in different ways to achieve the temperature you want or occasionally add more charcoal and wood midcooking.
Our Favorite Models: If flavor is your priority, charcoal is the way to go. We think a little babysitting is a small price to pay for exceptional barbecue. Our favorite smoker overall is the Weber Smokey Mountain Cooker Smoker 22". While it requires some attention to maintain your cooking temperature, it produces amazing food and is roomy enough to make lots of it. We also loved the 18.5" Classic Pit Barrel Cooker. It’s a great no-frills model and produces food that rivals our winner’s. It lacks temperature controls and runs hotter than most smokers, but for some, this lack of control might actually be an advantage—you can’t fuss even if you wanted to. Just load the smoker with food and walk away; when you return, there’s perfect barbecue.
Gas Smokers: Good Barbecue, Convenience
Ribs made in a gas smoker (top) weren't as smoky or deeply flavored as ribs cooked in charcoal smokers (bottom) but were still very tasty.
Pros: The differences between charcoal and gas smokers reflect those between charcoal and gas grills. Gas smokers are easier and less messy to use. Propane tanks provide lots of fuel (we used ours for more than 20 hours during testing and still had more than half a tank left). Like gas grills, the best gas smokers are mostly set-and-forget. You turn on the gas and set your target temperature, which it achieves quickly and then maintains. It’s possible to stay in your desired cooking zone with no adjustments—a more hands-off experience than charcoal.
Gas smokers excel at maintaining low temperatures, so salmon cooked in one (left) was exceptionally moist and tender, though not as smoky as salmon cooked in a charcoal model (right).
Cons: Because gas smokers maintain lower temperatures effortlessly, food cooked in them can be especially tender and moist—it just isn’t quite as richly flavored or intensely smoky as food cooked in a charcoal smoker.
Gas smokers often come in cabinet-style designs, resembling mini fridges with shelves that your food sits on as it’s being smoked. They can be harder to assemble—the model we tested took about an hour and a half to put together. Often, the pans used to hold wood chips or chunks are small; you’ll need to refill them periodically to ensure that you get smoke flavor. With the model we tested, we replenished the wood chunks every hour.
Our Favorite Model: The Masterbuilt MPS 340/G ThermoTemp XL Propane Smoker is a fine option for folks who don’t mind sacrificing a little flavor for convenience. It’s a pain to assemble, but it turns out succulent, lightly smoked barbecue with little or no babysitting needed.
Electric Smokers: Easy to Use, Mediocre Barbecue
Finished ribs in a cabinet-style electric smoker
Pros: At best, electric smokers are even easier to use than gas smokers. Like gas smokers, you can set and forget them, and because they’re good at maintaining low temperatures, your food will always come out tender and moist. Better still, they pull an unlimited supply of electricity straight from your outlet—you’ll never have to replenish your fuel.
Chicken cooked in an electric smoker (left) wasn't nearly as smoky or richly flavored and colored as chicken cooked in a charcoal smoker (right).
Cons: The food they make just doesn’t taste like barbecue. With the model we tested, everything we cooked tasted only very faintly smoked, even though we fed the smoker a constant stream of wood. Sometimes we couldn’t tell the food had been smoked at all.
Because the wood in an electric smoker never burns outright, food cooked in an electric smoker (right) lacks the coveted smoke ring found in barbecue cooked in a charcoal or gas smoker (left).
This is because the smokers' electrical heating elements never get the wood hot enough to burn outright. Instead, the wood just smolders, generating weak smoke without the array of flavor molecules produced in wood burned in charcoal or gas smokers at higher temperatures, as Goldwyn and food scientist Greg Blonder have shown. In addition, the food cooked in an electric smoker lacks a smoke ring. Because the wood smolders in an electric smoker, the chemical reactions required to form that smoke ring never occur.
Our Favorite Model: If you really want to make barbecue and space or fire hazards are issues, the Bradley Smoker Original 4 Rack Electric Smoker is an acceptable option. You won’t get competition-worthy barbecue, but it’s compact and easy to use.
