If you have a gas grill but haven’t bought a smoker yet, you can still cook some mighty good smoked meat. With an indirect cooking area and a suitable way to produce wood smoke, that grill can handle a pork tenderloin, chicken, ribs and other cuts without keeping them directly over a flame.

The challenge is getting enough heat to the wood while keeping the cooking area at the temperature the food needs. Once you work out that balance, the process is fairly straightforward, although a gas grill will usually give you a lighter smoke flavor than a dedicated charcoal or wood-burning smoker.

This guide focuses on gas grills with independently controlled burners that allow an indirect setup. It applies to both propane and natural gas models when used as designed, while my propane smoker guide covers vertical cabinet smokers. You can compare the other options in my Ultimate Guide to Smokers.

How Does a Gas Grill Work as a Smoker?

For smoking on a gas grill, the lit burner supplies the heat and a separate wood source supplies the smoke. The food sits above a burner that is turned off, with the lid closed so hot air can circulate around it.

This is an indirect cooking setup, and it lets you cook more gently than placing the meat directly above a lit burner. The grate on the indirect side still gets hot, but the food isn’t receiving the same concentrated heat from the flame immediately below it.

The wood usually sits in a built-in smoker box or a compatible accessory positioned over a lit burner. As the box heats, smoke enters the cooking chamber and flavors the food.

Unlike a charcoal smoker, most gas grills don’t have cooking vents that you adjust to regulate the fire. You control the heat with the burners and leave the grill’s designed ventilation openings unobstructed.

Why Use a Gas Grill for Smoking Meat?

The biggest advantage is being able to use a cooker you already own. You can learn the basics of smoking, try a few recipes and decide what you enjoy cooking before buying another piece of equipment.

A gas grill also gives you an easy way to combine indirect cooking with a direct finish when the recipe calls for it. A thick steak can cook gently on the indirect side before moving over a lit burner for a sear, while chicken can finish with more heat when you want to improve the skin.

The limitations are the grill’s lowest usable temperature, the amount of indirect space available and the way smoke moves through the cooking chamber. Gas grills are ventilated by design, so don’t expect one to hold smoke like a tightly controlled smoking cabinet.

That doesn’t make the cook unsuccessful. The goal is properly cooked meat with a useful amount of wood flavor, and you can accomplish that without filling the backyard with a cloud of smoke.

Essential Equipment for Smoking on a Gas Grill

You’ll need a grill that supports indirect cooking, enough fuel for the planned cook and a smoking accessory approved for the grill. A built-in smoker box is convenient, while a compatible stainless-steel box can work well when the grill doesn’t include one.

A digital thermometer with a probe beside the food is especially useful because the thermometer in the lid measures a different location. A meat probe lets you follow the internal temperature without opening the lid, and an instant-read thermometer helps confirm doneness in other places.

Keep long tongs and heat-resistant gloves handy, along with a heatproof place to put a hot smoker box if it must be removed. A small drip pan can be useful where the grill’s instructions allow it, but don’t block burner ports, drainage or airflow with an improvised pan arrangement.

For a propane grill, check the tank before a long cook. A natural gas grill avoids that particular refill issue, but it still needs its proper supply connection and operating pressure, so don’t alter either fuel system to change the grill’s temperature range.

Choosing Wood and a Smoke Source

A Smoker Box Is a Good Starting Point

If your grill has a built-in smoker box, use its loading and burner instructions. For an accessory box, check whether it is intended to sit on the cooking grate or below it on the heat shields, since those locations aren’t interchangeable for every product.

Use the recommended amount of wood chips and keep the box in its supported position over a lit burner. Start with a modest load rather than packing it tightly, which makes it easier to see how much smoke the setup produces and how quickly the wood is consumed.

Follow the accessory’s wood-preparation directions, including any soaking instructions it specifically requires. The more useful things to learn are how much heat the box needs to start smoking and how little it needs to keep working once it is hot.

My smoker-box guide takes you through loading, heating, refilling and troubleshooting this accessory in more detail.

A Foil Packet Can Be an Option

A small foil packet gives you a simple way to try smoking without buying a box. Put a modest handful of wood chips in heavy-duty foil, fold it into a compact pouch with a little room inside and make several small holes in the top for smoke to escape.

For step-by-step photos, see my guide on how to make a foil woodchip pack.

Position it only where the grill’s instructions allow, commonly on the cooking grate over a lit burner. Don’t put foil directly over burner ports, wrap the grill’s heat shields or line the bottom of the grill with it.

A packet is less convenient to refill than a box, so prepare a spare before lighting if you expect to need one. Handle a used packet as hot metal containing hot wood and ash, rather than setting it on a side shelf that may not tolerate the heat.

A Pellet Tube Is Another Option

A pellet tube can also provide smoke on a gas grill, and it doesn’t depend on heat from a burner to keep the pellets smoldering once they’re properly lit. It does need airflow, so place it in a position allowed by the grill and tube manufacturers, with room around it for air to reach the pellets rather than tucked beneath a pan or crowded against the food.

The gas burners still provide the cooking heat, while the tube supplies the smoke. My guide to using a pellet tube for smoking meat covers how to fill it, light it and keep it going.

Choose a Wood You Enjoy

Pecan is one of my favorites, while apple and cherry are good choices for a lot of pork and poultry cooks. Hickory or oak can also work well, depending on the food and how much wood flavor you want.

My Smoking Wood Guide explains the options in more detail. For a first cook, use one wood and keep the amount moderate so you have a useful starting point for the next meal.

How to Smoke Meat on a Gas Grill

Prepare the Grill

Set up outdoors in the grill’s approved location, observing its required clearances from structures and combustible materials. Check the grease tray and drainage system, clean the cooking grates and remove the old grease and food debris that could become a problem during a longer cook.

Inspect the gas hose and connections, and perform the leak checks required by the manufacturer. Don’t light a grill that has a known leak or a persistent gas odor, and don’t use a flame to check a connection.

Make sure the burner tubes, heat shields and cooking grates are installed correctly. A smoking accessory shouldn’t require removing a safety component or altering the burner system to make room for it.

Plan the Indirect Cooking Area

Look at the direction the burners run beneath the grate before deciding where the food will go. On many grills, the burners run front to back, so leaving a burner off creates a strip of indirect cooking space above it. Other grills use a different layout, and the control knob positions alone won’t tell you which area is protected from direct heat.

On a two-burner grill, you may be able to light one burner and place the food over the other. On a grill with three or more burners, one outside burner may provide enough heat for a smoking cook, or you may use the outside burners with food over an unlit center burner if that holds the temperature the recipe needs.

The right arrangement is the one that gives you both a suitable cooking temperature and enough indirect space for the entire piece of meat. If the thin end of a pork loin extends over the lit burner, it can cook much faster than the rest.

My two-zone grilling guide explains the placement in more detail. A compact grill with a single burner may need a manufacturer-designed indirect system, so don’t assume turning the flame down makes the whole grate indirect.

Position the Smoke Source

Place the smoker box or foil packet where it will receive heat from a burner you intend to use. It generally belongs on the heated side, while the food belongs in the indirect area.

If the accessory sits below the cooking grate, install it while the grill is cold unless its instructions provide a safe way to add it later. Plan for refilling before the grate and everything underneath it become too hot to handle casually.

Leave space around the food and the smoke source for normal circulation. You don’t need to seal the lid or cover rear openings to keep the smoke in, and doing so can interfere with the grill’s safe operation.

Light and Preheat the Grill

Open the lid and follow the grill’s lighting procedure, including the specified burner sequence. If a burner fails to light, turn it off and allow the full clearing time in the manual before trying again.

Preheat as directed, then establish the burner arrangement you chose for indirect cooking. Get the wood source working according to its instructions before making the final adjustment to your cooking temperature.

Some smoker boxes need a higher burner setting to get started than they need afterward. Once smoke is established, reduce the operating burners to the settings that hold your intended cooking temperature rather than continuing with the preheat settings.

Settle at the Cooking Temperature

Place the cooking probe in the indirect area near where the meat will sit, keeping the tip clear of the grate and leaving space between it and the food. Close the lid and watch how the temperature behaves before loading the grill.

For a first low and slow cook, a target around 250°F (121°C) is a useful place to begin if your grill can hold it with a normal, stable burner setting. Make small adjustments and give them time to affect the temperature inside the closed grill.

Don’t operate a knob between its off and low positions to create a smaller flame, and don’t modify the regulator to force the grill below its intended range. If it runs steadily at 275°F (135°C) but struggles at a lower setting, choose a recipe that works at that temperature.

Add the Food and Close the Lid

Place the meat entirely over the unlit area, leaving room around it for heat and smoke to circulate. Position the thicker part toward the warmer side when that suits the cut, and keep delicate edges farther from the lit burner.

Insert a meat probe where the recipe directs, close the lid and allow the grill to recover. Cold food and a brief lid opening can lower the reading temporarily, so don’t immediately turn the burner up to compensate.

If you’re using a drip pan, keep it in the approved location and check that it doesn’t block the grill’s normal drainage. Water in a permitted pan can keep collected drippings from scorching, but it won’t make overcooked meat juicy.

Maintain the Heat and Smoke

Watch the cooking temperature and check the smoke source as needed without opening the lid every few minutes. Wind, outside temperature and the amount of food can all change how the grill behaves, even when the burner knob hasn’t moved.

Refill a smoker box using its designated method, or replace a packet with gloves and long tongs when the setup allows it. Don’t lift a large hot grate while balancing food and trying to reach an awkward box underneath it.

You don’t need a continuous heavy plume for the entire cook. Wood can provide flavor with fairly faint smoke, and adding another load every time the smoke becomes hard to see can use a lot of wood without improving dinner.

Check that the burners remain lit, especially in changing weather or at low settings. If a flame goes out, shut off the gas and follow the manufacturer’s clearing and relighting procedure before continuing.

Finish According to the Recipe

Use internal temperature and tenderness to judge doneness, rather than assuming the cooking time will match another grill exactly. A larger roast can take considerably longer than expected, while a lean cut can go from ready to overcooked while you’re waiting for a particular number of hours.

Check different pieces individually, and rotate or reposition food when one side is cooking faster. Follow the recipe’s resting directions, using my Smoking Times and Temperatures Chart for planning rather than as a guarantee of the finishing time.

Recommended Smoking Temperatures for a Gas Grill

For ribs, pork butt and recipes intended for low and slow cooking, 225–275°F (107–135°C) is a useful range if your grill can maintain it safely. You don’t need to insist on 225°F (107°C) when a slightly warmer, steady cook suits the recipe.

Chicken often benefits from hotter indirect cooking, around 300–350°F (149–177°C), particularly when skin texture matters. Keep the food over the unlit burners even when you’re cooking hotter, unless you deliberately move it to direct heat for a finishing step.

A gas grill can also handle a gentle cook followed by a sear. My reverse-seared ribeye guide explains the approach, although the wood source and burner arrangement should follow the setup you’re using here.

Tips for Getting Better Smoke Flavor

Choose a smoke source that actually works at your operating temperature before committing to a long cook. A box that only produces smoke with the grill far hotter than the recipe requires isn’t giving you a useful smoking setup.

Keep the lid closed as much as practical, but leave the grill’s ventilation alone. Smoke leaving the cooking chamber is normal, and blocking the openings to trap it can create a safety problem.

A gas grill will often produce a gentler smoke flavor than a dedicated smoker, particularly on short cooks. Start with realistic expectations, taste the results and make one change at a time rather than trying to compensate with an oversized wood load.

There is no fixed internal temperature at which meat suddenly stops accepting smoke flavor. Use additional wood according to the flavor you want and the accessory’s instructions, rather than treating one thermometer reading as an automatic stopping point.

Common Gas Grill Smoking Problems

The Grill Runs Too Hot

Check how many burners are lit, whether the smoke source is adding extra heat and where you’re measuring the cooking temperature. Turn off unnecessary burners and adjust the remaining ones within their normal operating range.

If the grill still runs too hot, don’t crack the lid for hours or alter the gas system to force a lower reading. Choose a recipe suited to the temperature it can hold, or use a different cooker for that job.

The Wood Won’t Smoke

Confirm that the box or packet is receiving enough heat and is positioned as its instructions require. A box sitting over an unlit burner may remain too cool even though the cooking area is warm enough for the food.

If increasing heat beneath the box also overheats the indirect side, try a different approved position or accessory arrangement. Don’t put loose chips into the burner area or remove heat shields to get them closer to a flame.

The Food Is Burning Underneath

Make sure no burner is lit directly below the food, and check whether the meat extends into the hot zone. A thermometer reading in the indirect area won’t protect an edge that hangs over a lit burner.

Radiant heat from the adjacent hot area can still affect the food, so give it more separation or rotate it as needed. If the grill is too small to provide enough protected space, reduce the size of the cook.

The Smoke Flavor Is Too Mild

First make sure the wood is producing smoke during a useful part of the cook. If it is, consider a modest increase in wood or a different wood variety on the next attempt, staying within the box’s capacity and the grill’s approved setup.

Best Foods to Smoke on a Gas Grill

Pork tenderloin, chicken thighs, thick pork chops and a manageable batch of ribs make useful first projects. They let you learn the burner arrangement and smoke source without making an overnight cook your first experiment.

My smoked pork tenderloin is one place to start, provided you follow its cooking temperature and finishing instructions. Pick food that fits comfortably in the indirect area rather than covering every available inch of grate.

Pork butt is a good longer project once you know the grill can hold temperature and you have sufficient fuel. My pork butt guide covers the process, but plan for the length of the cook and the number of wood refills your setup may need.

A large brisket can be a challenge on a small gas grill because it needs both time and indirect space. Learn the setup with smaller cuts before making an expensive brisket your test of whether the grill can do it.

Cleaning and Maintaining Your Gas Grill

When the food is finished, shut down the grill and gas supply according to the manufacturer’s instructions. Let the smoking accessory and any wood ash cool completely before removing them for cleanup.

Clean the cooking grate, empty the grease collection system and remove loose deposits from the cooking chamber as needed. Long smoking cooks can leave more accumulated fat than a quick burger cook, so give the grease path attention before the next high-heat grilling session.

Keep burner openings and air passages clear using the maintenance procedure in your manual, and inspect the gas hose periodically. Don’t enlarge burner ports or wrap heat shields and the grill floor in foil as a shortcut for easier cleanup.

My smoker cleaning guide covers the broader principles, while the burners, gas connections and individual grill components should be maintained as their manufacturer directs.

If you’re considering adding water, the water-pan guide explains when it can help and how to avoid blocking heat, airflow or grease drainage. When the cook is finished, use the smoker shutdown guide before handling the smoking accessory and cooled grease.

Final Thoughts

Smoking on a gas grill comes down to giving the food an indirect place to cook and giving the wood enough heat to provide smoke. Once those two things work together at a steady temperature, you have a useful way to make smoked meat with equipment you already own.

Start with a manageable recipe, keep notes on the burner settings and wood source, and adjust based on what you taste. You may eventually want a dedicated smoker, but there’s no reason to leave good barbecue waiting until then.
