The ingredient list for this smoked mushrooms recipe is super simple, and you likely have everything you need at home already. Only six ingredients are required to make these savory smoked mushrooms, and there’s plenty of room for modifications depending on what you have on hand.

Here’s exactly what you’ll need to make these smoked mushrooms:

  • White Button Mushrooms: Perfect for smoking because they’re easy to cook and have a naturally mild flavor. White buttons can be swapped for crimini, portobello slices, or wild mushrooms.
  • Butter: Unsalted is preferred so you can better control the amount of salt added
  • Salt & Black Pepper: Adjusted to taste
  • Dijon Mustard: Amplifies flavor, though it can be swapped for stone ground mustard or omitted if preferred
  • Fresh Parsley: Optional, for garnish and a pop of color

Ingredient Swaps and Suggestions

This recipe is great as is, but there is room for some simple modifications to make it truly your own. Here are some of our recommendations:

  • Make an herb compound butter: Combine melted butter with dried herbs such as rosemary, thyme, or oregano. Whisk to combine before coating the mushrooms.
  • Add minced garlic and a squeeze of fresh lemon juice
  • Add two tablespoons of honey for sweet and savory smoked mushrooms
  • Swap Dijon mustard for balsamic vinegar

Serving Suggestions

These smoked mushrooms taste perfect on their own, but they taste even better when paired with equally delicious side dishes. Here are some suggestions:

Quick Tips

  1. If you don’t have a smoker, you can still have smoky mushrooms by adding ½ teaspoon of smoke flavor to your mushrooms, then bake at 425°F for 20-25 minutes or until tender. 
  2. Instead of smoking your mushrooms, place your skillet on a grill preheated to medium-high heat. Cook with the lid on for about 20 minutes.

Storage & Reheating

This recipe for smoked mushrooms makes 4-6 servings, depending on if they are the side dish or the main course. That said, it’s super easy to make a double – or triple-batch of this recipe with little added prep time.

As for leftovers, you can store leftover smoked mushrooms in an airtight container and keep them in the fridge for up to 3-4 days. 

Alternatively, if you want your smoked mushrooms to last longer, you can freeze them in an airtight container (or freezer bag) for up to three months. 

When you’re ready to reheat the leftover smoked mushrooms, place them on a baking sheet, then cover them in foil, and heat in the oven at 275°F for 10-12 minutes or until the mushrooms are fully reheated.


How do you smoke mushrooms without a smoker?

If you don’t have a smoker, you can swap it for your grill. First, add the mushrooms to your skillet, followed by the butter chunks and spices, then let them cook on indirect heat with the lid on for 20 minutes.

Can you cold-smoke mushrooms?

Yes, you can cold-smoke mushrooms, though they will have a more subtle smoky flavor and slightly more chewy texture. To cold smoke, set the smoker to 75°F and let the mushrooms smoke for 2-2 ½ hours.

How do you clean mushrooms?

Since mushrooms absorb a ton of water, it’s best not to run them underwater to clean them. Instead, carefully wipe them with a wet paper towel to remove excess dirt before cooking.
