Air Fryer Keto Mushrooms - Crispy, Savory, and Fast

Prep Time10 minutes
Cook Time12 minutes
Total Time22 minutes
Servings: 4 servings

Ingredients

  • 1 pound cremini or white button mushrooms, cleaned and halved (quarter larger ones)
  • 2 tablespoons unsalted butter, melted (or ghee for dairy-free paleo)
  • 1 tablespoon olive oil (or avocado oil)
  • 3 cloves garlic, finely minced
  • 1 teaspoon onion powder
  • 1 teaspoon dried Italian seasoning (or 1/2 tsp dried thyme + 1/2 tsp dried oregano)
  • 1/2 teaspoon smoked paprika (optional, for depth)
  • 1/2 teaspoon sea salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 1 tablespoon fresh parsley, finely chopped (for garnish)
  • 1 tablespoon grated Parmesan or nutritional yeast (optional, for finishing)
  • Lemon wedges, for serving (optional)

Instructions

  • Preheat the air fryer: Set to 400°F (200°C) for 3–5 minutes so the basket is hot when the mushrooms go in.
  • Prep the mushrooms: Wipe mushrooms with a damp paper towel to remove dirt. Trim stems if dry. Halve or quarter for even cooking.
  • Make the seasoning: In a large bowl, whisk melted butter, olive oil, garlic, onion powder, Italian seasoning, smoked paprika, salt, and pepper.
  • Toss to coat: Add mushrooms to the bowl and toss until every piece is glossy and well-seasoned.
  • Load the basket: Arrange mushrooms in a single layer in the air fryer basket. A little overlap is fine, but avoid packing them tightly.
  • Air fry: Cook for 8–10 minutes, shaking the basket halfway. They’re done when browned on the edges and tender in the center.
  • Finish and taste: Transfer to a bowl, sprinkle with parsley and Parmesan or nutritional yeast if using. Squeeze a little lemon over the top. Taste and add a pinch of salt if needed.
  • Serve hot: Enjoy right away while crisp on the edges.
