The products below include gas-and-charcoal combos with attached offset smokers, a gas grill with a charcoal insert, and a pellet smoker—but they are not all gas grills with a traditional built-in smoker box.

Our Picks: Best Gas Grill With Built In Smoker Box reviews
Royal Gourmet ZH3006Y: Best Overall Gas and Offset Smoker Combo
The Royal Gourmet ZH3006Y is a multi-fuel grill with two gas burners, a charcoal grilling chamber, a side burner, and an attached offset smoker. It is the closest match here for shoppers who want gas convenience and a dedicated place to smoke food. It does not use a small built-in smoker box; its offset smoker is a separate chamber attached to the main grill.
The listed total cooking area is 1,020 square inches, divided among the main cooking area, warming rack, and offset smoker. The two main burners provide 12,000 BTU each, while the side burner provides 10,000 BTU. The height-adjustable charcoal pan gives you some control over the distance between the coals and the food, and piezo ignition is included for the gas burners.
This setup makes sense if you like switching between fast gas grilling, charcoal cooking, and smoking without buying separate cookers. The trade-off is its size and complexity: at 87.1 pounds and nearly 68 inches wide, it needs a spacious patio and more setup and cleaning than a basic gas grill. Some owners report that assembly takes effort, so plan time for putting it together.
Pros:
- Combines gas, charcoal, and an attached offset smoker.
- Large listed cooking area spread across three cooking zones.
- Includes a side burner for sauces or other side dishes.
- Adjustable charcoal pan helps manage charcoal heat.
Cons:
- Large, heavy footprint may not suit smaller patios.
- More parts and fuel types mean more setup and maintenance than a standard gas grill.
Verdict: Choose the Royal Gourmet if you want the broadest mix of gas grilling, charcoal cooking, and offset smoking in one unit and have room for its substantial footprint.
Nexgrill 4-Burner: Best for Gas Grilling With a Charcoal Option
This Nexgrill is primarily a propane grill, with four main burners and a side burner. Its removable charcoal tray adds another way to cook and bring charcoal flavor to food. That makes it a flexible option for someone who wants gas as the everyday fuel but would like to use charcoal at times.
The listing gives the grill 461 square inches of cooking surface, plus a 160-square-inch warming rack. It also lists 60,000 BTU of output and cast-iron cooking grates. Its charcoal tray is not an offset smoker or a dedicated smoker box, so it is better suited to grilling with charcoal than to choosing this model specifically for low-and-slow smoking.
The grill’s alloy-steel frame and powder-coated finish are described as heavy-duty and rust-resistant, though any outdoor grill benefits from regular cleaning and protection from the elements. At 106.9 pounds, it is also a substantial piece of equipment. Compared with the Royal Gourmet and Sophia & William, it gives up the attached smoker chamber in exchange for a more straightforward gas-first layout.
Pros:
- Four main burners and a side burner provide several cooking zones.
- Removable charcoal insert offers an alternative to propane.
- Cast-iron grates are specified for heat distribution and durability.
- Includes a warming rack and removable grease tray.
Cons:
- No attached offset smoker or dedicated smoker box is listed.
- Its listed cooking area is smaller than the two gas-and-offset-smoker combos here.
Verdict: Pick the Nexgrill if you mainly want a propane grill and see the charcoal tray as a useful extra, not as a replacement for a dedicated smoker.
Monument Grills Denali 605: Best for Smart, High-Capacity Gas Grilling
The Denali 605 is a six-burner gas grill with a side burner, digital temperature display, and Bluetooth app control. It is not presented as a smoker-box grill, so consider it here as a gas-focused alternative rather than a smoking pick. Its main appeal is a roomy cooking surface paired with tools for monitoring heat and cooking time.
The listed total cooking area is 895 square inches, including 640 square inches of primary cooking space and a 225-square-inch warming rack. The grill has a viewing lid window, a meat probe, and knob lights that indicate the grill’s heat status. It can use propane or natural gas with the separately sold conversion kit specified by the manufacturer.
The connected features may be useful if you want to check temperatures from your phone rather than stay beside the grill. However, app control and a meat probe do not make this a substitute for a dedicated smoker. The grill and accessory may also arrive in separate packages, so keep that in mind when planning delivery and assembly.
Pros:
- Six main burners and a side burner provide ample gas-grilling capacity.
- Large cooking area with a separate warming rack.
- Bluetooth app control, digital display, and included grill probe.
- Designed for propane or natural gas with the specified conversion kit.
Cons:
- No smoker box, charcoal insert, or dedicated smoking chamber is listed.
- The natural-gas conversion kit is sold separately.
Verdict: Choose the Denali 605 if you value smart features and a large gas-grilling area more than built-in smoking capability.
Traeger Woodridge: Best for App-Controlled Pellet Smoking
The Traeger Woodridge is a wood-pellet grill and smoker, not a gas grill. It earns a place in this comparison as an alternative for shoppers whose main goal is smoking with controlled heat. Rather than using a gas burner and smoker box, it uses wood pellets and app-based temperature control.
The Woodridge offers 860 square inches of cooking area and six cooking modes: grilling, smoking, baking, roasting, braising, and barbecue. Its listed temperature range is 180°F to 500°F, and the app can be used to monitor and control cooking. The EZ-Clean Grease & Ash Keg is designed to collect grease and ash in one place, which can simplify cleanup.
Some owners find the app convenient for monitoring a cook, while assembly can take effort. Pellet cooking also means this is the wrong choice if you specifically need a gas grill or want to use a smoker box with gas burners. If you are open to changing fuel types, however, it offers a dedicated smoking approach with a broad temperature range.
Pros:
- Designed for both smoking and several other cooking methods.
- App-based temperature control and monitoring.
- Large listed cooking area of 860 square inches.
- Grease and ash collection system is designed to simplify cleanup.
Cons:
- Uses wood pellets, not gas.
- Assembly may take time and effort.
Verdict: Choose the Traeger if smoking and app-controlled temperature management matter more to you than owning a gas grill.
Sophia & William 3-Burner Combo: Best for Separate Gas and Charcoal Zones
This combo gives you a gas grill, a charcoal grill, and an attached offset smoker. Like the Royal Gourmet, it is not a gas grill with a small built-in smoker box; it uses a separate smoker chamber. Its split cooking setup may suit you if you want to use gas for faster meals and charcoal or the offset smoker for a more involved cook.
The listed total cooking area is 840 square inches, divided among the main cooking surface, warming rack, and offset smoker. Three stainless-steel gas burners provide a listed 30,000 BTU total. On the charcoal side, a three-level adjustable pan lets you change the coal-to-food distance. Pull-out ash and grease trays are included to help with cleanup.
Owners describe the combination as a way to get several cooking options without buying separate grills, and some find it manageable to assemble. Still, the three cooking areas add bulk and require more cleaning than a single-chamber gas grill. Compared with the Royal Gourmet, it has a lower listed total cooking area and fewer gas burners, but it still offers a substantial multi-fuel setup.
Pros:
- Combines gas, charcoal, and an attached offset smoker.
- Separate cooking zones let you choose a fuel for different foods.
- Adjustable charcoal pan supports different heat levels.
- Removable ash and grease trays help with cleanup.
Cons:
- Its multi-section design needs more space than a basic gas grill.
- More cooking zones mean more parts to clean and maintain.
Verdict: Choose the Sophia & William if you want separate gas and charcoal grilling areas plus an attached offset smoker in one backyard unit.
How to Choose a Gas Grill With a Built-In Smoker Box
Check how the grill creates smoke
“Smoker box” can mean a small box that holds wood chips, but some combo grills use a separate offset smoker chamber, while others use a charcoal insert or wood pellets. These designs are not interchangeable. If you want to smoke food while using gas, confirm that the grill has a smoking feature suited to that task. An attached offset smoker offers a separate cooking chamber; a charcoal tray adds charcoal cooking but is not the same as a dedicated smoker box.
Choose the fuel setup that fits your cooking habits
A gas grill is convenient for quick cooks and simple heat adjustment. A charcoal section gives you a different fuel option, while a pellet grill uses wood pellets rather than gas. Think about whether you want one primary fuel with an occasional alternative or a true multi-fuel setup. If you need gas specifically, a pellet model such as the Traeger Woodridge will not meet that requirement.
Match cooking space to your usual meals
Compare the primary grilling area separately from the warming rack and smoker chamber. A large total area may be split across several zones, so it does not all function as one continuous cooking surface. Consider how many people you usually cook for and whether you expect to grill and smoke at the same time.
Look beyond burner count and BTU claims
Burner count and listed heat output can help you compare gas models, but they do not tell the whole story. Also consider how many cooking zones you want, whether there is a side burner, and how easily you can adjust charcoal heat. A grill with several fuel systems may offer more options but can take more effort to use and maintain.
Measure your patio and plan for assembly
Combo grills can be wide and heavy. Measure the spot where you plan to use and store the grill, leaving room to work around it. Check the listed dimensions and weight, and account for assembly time. A compact gas grill may be more practical if your outdoor space is limited or you do not want to manage several cooking chambers.
Consider cleanup and ongoing care
Grease, ash, charcoal, and wood pellets each create different cleanup tasks. Removable trays can make disposal easier, but the grill still needs routine cleaning. If you plan to smoke often, consider whether the design gives you convenient access to the smoker area and its ash or grease collection points.
Confirm the gas type and any extra parts
Check whether the grill uses propane, natural gas, or both. Some models require a separately sold conversion kit to change fuel types. Do not assume a grill can connect to your existing gas line just because it has a gas burner; confirm its stated fuel compatibility and required accessories before buying.
Frequently Asked Questions
What is the difference between a smoker box and an offset smoker?
A smoker box is generally a smaller container for wood chips used alongside a grill’s heat source. An offset smoker is a separate chamber attached to the grill, with its own cooking area. The Royal Gourmet and Sophia & William products listed here have attached offset smokers rather than a conventional small smoker box.
Can I smoke food on a gas grill?
Some gas grills can be used for smoking with a compatible smoker box or other designed smoking feature. The products in this list vary: the Royal Gourmet and Sophia & William have attached offset smokers, while the Nexgrill lists a charcoal insert rather than a smoker chamber. Check the product details and instructions for the model you choose.
Which option here is closest to a gas grill with built-in smoking?
The Royal Gourmet ZH3006Y is the closest match if you want gas burners and a dedicated smoking area in one unit. It uses an attached offset smoker, not a built-in smoker box. The Sophia & William combo is another gas-and-offset-smoker option.
Does the Nexgrill have an offset smoker?
No offset smoker is listed for the Nexgrill. Its described smoking-related feature is a removable charcoal insert, which offers a charcoal cooking option but is not the same as a dedicated smoker chamber.
Is the Traeger Woodridge a gas grill?
No. The Traeger Woodridge is a wood-pellet grill and smoker. It may suit shoppers focused on smoking and app-based temperature control, but it does not use gas.
Can the Monument Denali 605 use natural gas?
The product information says the Denali 605 can use propane or natural gas with the specified conversion kit, which is sold separately. Check compatibility and instructions before changing fuel types.
Final Recommendation
For shoppers seeking gas grilling plus a dedicated place to smoke food, the Royal Gourmet ZH3006Y is the strongest match in this group because it combines gas burners, charcoal cooking, and an attached offset smoker. The Sophia & William is a worthwhile alternative if you prefer separate gas and charcoal grilling areas. If you only want charcoal flavor now and then, consider the Nexgrill; if you want a large connected gas grill without a listed smoker feature, consider the Monument. Choose the Traeger only if you are comfortable using pellets instead of gas.
