Juicy, tender, and dripping in bubbling garlic butter, these smoked cremini mushrooms deliver pure steakhouse luxury in under an hour. By dry-smoking the mushrooms first, every cap soaks up rich hardwood smoke before taking a cozy butter bath that will have everyone reaching for seconds.
The Secret to the Best Garlic Butter Smoked Mushrooms
As a pitmaster, I am always looking for smart ways to maximize grate space on the smoker. Whenever you have a long cook going, whether it’s a brisket, pork shoulder, or a rack of ribs, there is almost always extra real estate sitting empty. Throwing a pan of mushrooms on the pit is the ultimate way to use that open space while making a killer side dish to go with your main protein.
By taking a simple classic and splitting the process into two effortless steps, you transform humble cremini mushrooms into rich, tender bites coated in a glistening garlic butter glaze. Best of all, it takes virtually zero effort and cooks in an hour flat. It’s the kind of pitmaster side that effortlessly steals the show at any weekend cookout or family dinner. (And if you don’t have a smoker fired up, don’t worry, I’m also sharing quick oven and gas grill methods below so you can get that same rich, smoky flavor indoors!)
What You Need for Garlic Butter Smoked Mushrooms
This full 60-minute pellet grill process guarantees maximum smoke absorption and rich flavor.
- Cremini mushrooms, wiped clean
- Unsalted butter, cubed
- Garlic Cloves, minced
- Seasonings: kosher salt and black pepper
- Fresh Thyme
Chef Lori’s Pro Tip: The Dry-Smoke & Stir Method
Always smoke or dry-roast the mushrooms completely dry in your baking dish for the first 20 minutes before adding any fat. Because mushrooms are highly porous, adding butter at the start creates a liquid barrier on the surface that blocks smoke and heat from penetrating. Dry-roasting opens the pores first, and stirring every 15 minutes while the cubed butter melts ensures every mushroom is evenly coated in garlic butter.
How to Make Garlic Butter Smoked Mushrooms
This simple two-step smoking method guarantees maximum hardwood flavor and perfectly tender mushrooms every single time.
- Preheat the Pellet Grill: Fire up your pellet smoker to 250°F (121°C) using your favorite hardwood pellets for a rich, balanced smoke profile.
- Arrange the Mushrooms: Place the cleaned, dry cremini mushrooms in a single layer inside a baking dish or cast-iron skillet.
- Dry Smoke Phase: Place the dish, uncovered, on the smoker to smoke dry for 20 minutes, allowing the hardwood smoke to penetrate the porous caps without a liquid barrier.
- Season & Add Butter: Carefully remove the dish from the smoker. Top the mushrooms with the cubed butter and minced garlic, then sprinkle evenly with the salt and black pepper.
- Butter Bath & Stir: Return the dish to the pellet grill for another 30–40 minutes at 250°F, stirring every 15 minutes as the butter melts so every cap stays evenly coated in the bubbling glaze until tender. Garnish with fresh thyme before serving.

Garlic Butter Smoked Mushrooms FAQs
- Can I use frozen mushrooms for this recipe? Fresh mushrooms are strongly recommended. Frozen mushrooms release a massive amount of excess water as they thaw on the grill, which will boil the caps instead of smoking them and cause your garlic butter sauce to become watery and broken.
- Can I make these smoked mushrooms ahead of time? Yes, but for the best texture, do the 20-minute dry-smoke phase in advance and refrigerate the dry caps. When you are ready to serve, toss them in your baking dish with the cubed butter and seasonings, then run the final 30–40 minute butter bath on the smoker so they serve fresh and sizzling hot.
- What are the best types of mushrooms to smoke? Cremini (baby bella) mushrooms are the top choice because they retain their firmness under heat and absorb flavor well. White button mushrooms work great as a budget-friendly alternative, while sliced portobello caps or whole shiitakes add an even deeper, meatier flavor profile.
- Will the garlic burn during the cook? No, because the smoker is set to a low temperature of 250°F (121°C) and the minced garlic cooks suspended inside the melting butter. Stirring every 15 minutes keeps the garlic gently simmering in the liquid rather than baking onto dry metal, preventing any bitter, burnt notes.
How to Store and Reheat Leftover Smoked Mushrooms
Store leftovers in an airtight container in the fridge for up to 3 days. To keep the mushrooms tender and prevent the garlic butter sauce from separating or turning greasy, use one of these quick reheating methods:
- Stovetop (Best Overall): Warm a skillet over medium-low heat. Add the mushrooms and a small splash of water or broth (about 1 tablespoon) to help loosen the butter sauce. Stir gently for 3 to 5 minutes until heated through and glossy.
- Oven or Toaster Oven: Place the mushrooms in an oven-safe dish, cover loosely with foil to lock in moisture, and bake at 325°F (165°C) for 10 to 12 minutes until sizzling.
Garlic Butter Smoked Mushrooms Variations & Substitutions
Feel free to tweak this recipe based on what you’re throwing on the smoker or what’s sitting in your pantry.
- Mushroom Swap: Swap cremini for button mushrooms, portobellos (sliced), or shiitakes.
- Fat Options: Use clarified butter (ghee) or vegan butter alternatives for dairy-free needs.
- Herb & Spice Swaps: Stir in fresh thyme, rosemary, or a splash of Worcestershire sauce into the butter melt.
- Optional Add-ins: Fold in grated Parmesan cheese or red pepper flakes during the final stir.
Best Ways to Serve Garlic Butter Smoked Mushrooms
These savory mushrooms complement almost any main course or function perfectly on their own.
- Steakhouse Dinner: Serve piled high atop a seared ribeye, New York strip, smoked picanha, or beef tenderloin.
- Roasted Poultry Side: Pair alongside roasted chicken, turkey breast, or grilled pork chops.
- Gourmet Appetizer: Serve with crusty French bread or crostini to soak up the extra garlic butter sauce.
Other Ways to Make Garlic Butter Mushrooms
Don’t have a pellet smoker? You can easily replicate that deep, smoldering hardwood flavor with a conventional oven or a standard gas grill by adding 1/4 tsp of Hoosier Hill Hickory Smoke Powder to the garlic butter mixture.
Oven:
- Preheat and Dry Roast: Heat your oven to 250°F (121°C) and roast the dry mushrooms on a parchment-lined baking sheet for 20 minutes to dry them out.
- Season & Add Butter: Transfer the dry-roasted mushrooms to a cast-iron skillet or baking dish. Top with the cubed butter and minced garlic, then evenly sprinkle the salt, black pepper, and Hoosier Hill Hickory Smoke Powder over.
- Butter Bath & Bake: Return the skillet to the oven and bake at 250°F (121°C) for an additional 30–40 minutes, stirring every 15 minutes to keep the mushrooms coated in the bubbling glaze until tender.
BBQ Grill:
For this, you’ll need to set up the grill for 2-zone cooking (indirect and direct). Although your pan won’t be on the flames, you may want to use a foil pan here just in case.
- Set Up Indirect Heat: Set your grill to indirect cooking at 250°F (121°C), then roast the dry mushrooms directly over the indirect heat for 20 minutes.
- Season & Add Butter: Transfer the mushrooms to a heat-safe cast-iron skillet. Top with cubed butter and minced garlic, then sprinkle on the salt, black pepper, and Hoosier Hill Hickory Smoke Powder.
- Butter Bath & Grill: Place the skillet on the cool side of the grill and cook at 250°F (121°C) for 30–40 minutes, stirring every 15 minutes until tender and well-glazed.
