FAQ
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.
