Weber Premium Smoker Box Review: A Year of Turning My Gas Grill Into a Smoker

My Weber Genesis II E-310 has been the backyard workhorse for about four years now. It is a solid gas grill and I cook on it most weekends from March through November. But there was always this gap: the ribs were good, the chicken was good, and nothing tasted like it came off a charcoal or wood smoker. My neighbor cooks on a stick burner and his food has that deep, smoky backbone mine was missing. Last spring I picked up the Weber Premium Universal Stainless Steel Smoker Box for around $40 and dropped it over my left burner. That was 11 months ago. I have used it on everything from baby back ribs to whole chickens to a tri-tip I was not entirely sure how to handle. Here is the honest, long-term picture.

The short version: it works. It actually delivers smoke flavor on a gas grill, which is something I was not fully convinced was possible before I tried it. But there are limits to what a smoker box can do, and if you go in expecting it to replicate a dedicated offset smoker, you are going to be disappointed. What it can do is add a genuine wood-smoke note that makes your gas-grilled food taste like more than just gas-grilled food. For most backyard cooks who already own a gas grill and are not ready to buy a whole second cooker, that is a meaningful upgrade.

How I Have Used It This Year

My setup is a three-burner Genesis II with a stainless grate. The smoker box sits directly over my far-left burner, which I run on medium or medium-high to get the chips going while my center and right burners handle indirect heat for the cook. That is the basic method Weber recommends and it works well. I preheat the whole grill with the smoker box in place, lid closed, for about 12 to 15 minutes. By the time I put food on, the chips are already producing smoke. The box stays on for the entire cook, and I will sometimes add a second load of chips at the 45-minute mark if I am doing a longer cook like spare ribs or a pork shoulder cut.

In 11 months I have run apple, hickory, cherry, and mesquite chips through this box. Hickory gives the most aggressive smoke flavor, which I love on pork ribs but find a little heavy on chicken. Apple is my everyday chip now because it is mild enough to use without worrying about over-smoking something. Cherry is beautiful on chicken thighs and gives that dark exterior color that looks impressive on the platter. Mesquite burns hot and fast and I only use it for quick cooks like steaks or burgers where I want a hit of smoke in 15 minutes, not a slow build.

Build Quality: Where Weber Earns Its Price

The Weber smoker box is made from thick-gauge stainless steel. It is noticeably heavier than the cheaper cast-iron or thin-steel smoker boxes you will find for $10 to $15 on Amazon. The hinged lid stays put when you open it, which sounds minor until you have fumbled with a lid that flops off every time you reach inside to add chips mid-cook. The lid slots and the perforations in the bottom of the box are well-sized: big enough to let smoke out and heat in, small enough that chip fragments do not fall onto your burner covers and create a mess.

After 11 months of use the exterior has darkened and patched with that mottled gray that stainless gets when it lives over a gas flame, but there is zero rust, no warping, and the hinge still works exactly like it did out of the box. I have left it on the grill through rain a couple of times when I forgot to put the cover on. No issues. The cheap smoker boxes I tried before this one warped within a season and started dumping ash through the cracks. This one is solid.

Smoke Output and Flavor: Realistic Expectations

Here is where I want to be straight with you, because this is the question that actually matters. Yes, the Weber smoker box produces real smoke and yes that smoke gets into your food. But it is not the same experience as a charcoal grill with wood chunks, and it is nowhere near what a stick burner or a dedicated pellet smoker produces. A gas grill runs clean-burning fuel at controlled temperatures, which is great for consistency and terrible for building smoke flavor. The smoker box adds wood smoke to that equation, but you are still fighting the physics of a gas burner that wants to burn clean.

What I get in practice is a noticeable smoke note in the finished food, a thin smoke ring on cuts like chicken quarters and pork ribs that I cook low-and-slow on indirect heat, and a bark-like exterior on longer cooks that my gas-grilled food never had before. My family can taste the difference. Guests have asked if I finally broke down and bought a smoker. That is a meaningful result from a $40 accessory. But if you cut into something expecting the deep mahogany smoke ring and penetrating smoke flavor of competition BBQ, the smoker box will not get you there. It closes the gap; it does not eliminate it.

The Learning Curve: What I Got Wrong at First

The first two sessions with this box were underwhelming, and it was entirely my fault. I was soaking my chips in water for 30 minutes before loading them, which is old conventional wisdom that has since been mostly debunked. Wet chips take longer to start smoking and they produce more steam than actual combustion smoke. The first session I pulled the lid on my ribs after 45 minutes and could barely smell smoke. I almost returned the box. Instead I tried dry chips the next weekend and the difference was immediate. Dry chips start producing smoke within 10 to 12 minutes of the box going over the burner. Steam is not smoke. Skip the soak.

The other thing I learned is chip size matters more than I expected. Fine sawdust-style chips burn off in 20 minutes and leave you with an empty box and a long cook still ahead. Standard-cut chips give you about 45 to 60 minutes of production. Larger chips or small chunks last longest. I have started mixing a handful of wood chunks in with standard chips to extend the smoke window on two-hour-plus cooks. The box has enough interior volume to fit a mix like that without the lid not seating properly.

What the Box Does Not Do Well

The smoker box only holds enough wood for about one to two loads per cook. If you are doing a true low-and-slow cook for four or more hours, you are reloading chips mid-cook with the grill open and hot. Opening a hot grill to load chips into a box sitting directly over a burner requires some care. I use long tongs and a silicone glove and it is not a big deal, but it is an interruption. A dedicated smoker loads a full hopper or a big wood box and runs for hours untended. The smoker box is more hands-on.

The universally-compatible design also means it is not a perfect fit for every grill. On my Genesis II it sits between the grate bars and sits level without any drama. A friend tried his on an older char-broil with wider-spaced grates and it was a slightly awkward fit, though it still worked. Weber says it fits most gas, charcoal, and electric grills, and that is broadly true, but check your grate spacing against the box dimensions (12 x 3.5 x 2 inches) before ordering.

How It Compares to Cheaper Smoker Boxes

I burned through two cheap smoker boxes before this one. The first was a $12 thin-steel box that warped after about three cooks and stopped seating the lid flat. Once the lid gap opened up the smoke escaped sideways instead of going through the vents and into the cooking chamber. The second was a cast-iron box that held heat well but rusted along the interior seams within one season even though I tried to keep it dry. The Weber at four times the price of the cheap options has outlasted both of those combined and is still going strong. If you buy one smoker box, this is the one I would buy. If you are experimenting and not sure you want to commit to the method yet, the cheap ones will let you see if smoker box cooking fits your style before you spend $40.

Who This Is For

The Weber smoker box is the right purchase for someone who already owns a gas grill and wants meaningfully better smoke flavor without buying a dedicated smoker. If you cook for family and friends most weekends, do a mix of quick cooks like steaks and burgers and longer cooks like ribs and chicken pieces, and you have noticed your food tastes good but not smoky, this is the fix. It rewards a little attention to chip type and load size, but the learning curve is two or three sessions at most. It is also a good gift for a serious backyard cook who has good gear but does not have a smoker.

Who Should Skip It

If you already own a dedicated charcoal grill, an offset smoker, a pellet grill, or a kamado, you do not need this. Those cookers produce more smoke flavor than any box accessory can match. This is specifically for gas grill owners who want to cross the gap. It is also not the right tool if you want to do true competition-style low-and-slow barbecue for six-plus hours with heavy smoke penetration. For a backyard pork shoulder or competition-style brisket, a dedicated smoker gives you results a smoker box simply cannot replicate. Know what you are buying it for and it will deliver. Expect it to replace a real smoker and it will disappoint.
