You’re standing in the backyard, a cold drink in one hand and a spatula in the other. To your left, a rack of ribs is weeping fat onto a low-burning hickory fire. To your right, a stack of burgers is sizzling over a high-heat propane flame. This is the dream, right? Getting a propane grill and smoker in one unit sounds like the ultimate cheat code for backyard cooking. You get the speed of gas for a Tuesday night dinner and the deep, soulful flavor of wood smoke for a Saturday afternoon project.
But honestly, most of these hybrid machines are kind of a headache if you don’t know what you’re buying. People walk into a big-box store, see a massive shiny rig with dozens of knobs, and assume it’s a professional-grade kitchen. It isn't. Usually, it's two mediocre appliances bolted together. If you want a setup that actually produces a bark-heavy brisket and a seared ribeye, you have to look past the marketing fluff.
The Reality of the "All-in-One" Propane Grill and Smoker
Let's be real: heat management is the biggest hurdle. A propane grill is designed to vent. It needs high airflow so the gas burns cleanly and doesn't extinguish itself. A smoker, conversely, is a tomb. It’s meant to hold heat and trap smoke. When you try to force these two opposite philosophies into one chassis, physics usually wins.
Most consumer-grade hybrids, like the ones you'll see from Pit Boss or Oklahoma Joe’s, try to solve this by creating separate chambers. On one side, you have your standard three-burner gas setup. On the other, an offset firebox or a vertical smoking cabinet. The problem? Thin metal. If the steel is less than 12-gauge, your heat is going to leak out faster than a screen door in a hurricane. You’ll find yourself burning through propane tanks or bags of charcoal just trying to keep the temperature at 225°F.
Why Insulation Matters More Than Features
When you're shopping for a propane grill and smoker, ignore the built-in bottle openers and the LED-lit knobs. Look at the weight. A heavy grill is a stable grill. Thick porcelain-coated cast iron grates are great, but the thickness of the lid is what determines if you're actually smoking meat or just baking it in a drafty box.
I’ve seen people spend $800 on a combo unit only to realize the "smoker" side is basically a glorified warming rack because the seals are so poor. If you can see daylight through the lid when it’s closed, you're going to have a bad time. You can fix this with high-temp felt gaskets—basically a $20 DIY upgrade—but you shouldn't have to rebuild a brand-new cooker on day one.
The Two Most Popular Ways to Hybridize
There are basically two schools of thought here. You have the "Side-by-Side" and the "Vertical Propane Smoker."
The side-by-side models, like the Camp Chef Apex or the Oklahoma Joe’s Longhorn, give you two distinct cooking zones. One is gas; one is charcoal/wood. These are massive. They take up half your patio. They are awesome for hosting big parties because you can do corn on the cob on the gas side while the pork shoulder finishes on the other. But they are a beast to clean. You have two different ash management systems to deal with.

Then you have the propane-powered vertical smokers. These use a gas burner to ignite wood chunks or chips in a tray. Companies like Masterbuilt have dominated this space for years. These are much more efficient for strictly smoking. Why? Because propane is a remarkably stable fuel source. Unlike a stick burner where you're constantly poking the fire, a gas smoker is almost "set it and forget it." You turn the dial, wait for the wood to start wispy blue smoke, and go watch the game.
The Flavor Debate: Gas vs. Wood
Purists will tell you that using a propane-assisted smoker is cheating. They'll say the moisture from the propane combustion (water vapor is a byproduct of burning $C_3H_8$) ruins the bark.
That's mostly nonsense.
The moisture can actually help the smoke stick to the meat. The real downside isn't the gas; it's the lack of airflow. A traditional offset smoker moves a massive amount of air, which dries the surface of the meat and creates that crunchy, dark bark. A propane smoker is often too stagnant. To get around this, you have to be very careful with your water pan. Don't overfill it, or you'll end up steaming your ribs instead of smoking them.
Real Talk on Gas Safety
Don't ignore the grease. In a dedicated gas grill, grease falls onto "flavorizer bars" and vaporizes. In a smoker, grease accumulates. If your hybrid design allows grease from the smoker side to migrate toward the gas burners, you are looking at a literal fireball. Always check the drainage path. A good propane grill and smoker should have independent grease trays for each side.
Maintenance is the Part Nobody Talks About
You're going to have to clean this thing. Often.
Since you’re dealing with both ash and grease, you have a recipe for a concrete-like sludge if you let it sit. Every three or four cooks, you need to scrape the bottom of the smoking chamber. If you’re using the gas side for high-heat searing, that leftover smoke residue from the "smoker side" can actually flake off the lid and land on your food. It looks like black pepper, but it tastes like a campfire. Not in a good way.

What to Look for Before You Buy
- Total Cooking Surface: Don't just look at the total square inches. See how much is actually usable. Often, the "smoker" side is tiny, barely enough for a single brisket.
- BTU Output: For the gas side, you want at least 80 to 100 BTUs per square inch of cooking space. Anything less and you won't get a decent sear on a steak.
- Dampers and Vents: You need granular control. Look for a chimney that actually has a closing damper and side vents that feel sturdy, not floppy.
- Warranty: Brands like Weber or Napoleon offer decade-long warranties. Most combo units are made by "lifestyle" brands that might only give you a year or two. If the burners rust out in 14 months, you’ve just bought a very heavy piece of scrap metal.
Actionable Steps for Your Next Backyard Cookout
If you’ve already got a propane grill and smoker or you’re about to pull the trigger on one, here is how you actually make it work like a pro.
First, buy a third-party digital thermometer. The analog ones stuck in the lid are almost always wrong—sometimes by as much as 50 degrees. Place the probe right next to the meat, not at the top of the dome.
Second, if you're using the "smoker" side of a combo unit, pre-heat the metal with the gas burners for 15 minutes before you even start your wood fire. This gets the heavy steel up to temp quickly and prevents "creosote" (that bitter, black soot) from forming on cold meat.
Lastly, don't use wood chips. They burn up in five minutes. Use chunks. They smolder longer and provide a much more consistent flavor profile. If your tray is too small for chunks, get a "smoke tube" and fill it with high-quality pellets. It’s a cheap way to get an extra 4 hours of smoke without having to babysit the grill.

Backyard cooking isn't about having the most expensive gear; it’s about knowing the quirks of the machine you have. Manage your airflow, keep your grease trays empty, and stop peeking under the lid. If you're looking, you ain't cooking.
