Air Fryer King Oyster Mushrooms - Crispy, Savory, and Ready Fast

Prep Time10 minutes
Cook Time15 minutes
Total Time25 minutes
Servings: 4 servings

Ingredients

  • 1 pound king oyster mushrooms (also called king trumpet)
  • 1–2 tablespoons olive oil or avocado oil
  • 1 teaspoon soy sauce or tamari (for gluten-free)
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon smoked paprika
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon kosher salt (adjust to taste)
  • Optional: 1 teaspoon cornstarch or rice flour for extra crispness
  • Optional garnish: lemon wedges, chopped parsley, chili flakes, or a drizzle of sesame oil

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 clean with a damp paper towel. Trim the very end of the stem. Slice into 1/2-inch rounds or batons. For “scallop-style,” cut thick rounds and lightly score a crosshatch on both cut sides.
  • Season: In a bowl, toss mushrooms with oil and soy sauce. Add garlic powder, onion powder, smoked paprika, pepper, and salt. If using cornstarch, sprinkle it over and toss again to coat evenly.
  • Arrange in the basket: Place in a single layer with a little space between pieces. Work in batches if needed. Lightly spritz the tops with oil for extra browning.
  • Air fry: Cook at 400°F (200°C) for 8–12 minutes, shaking or flipping halfway. They’re done when edges are browned and the centers feel tender but springy.
  • Finish and serve: Squeeze a little lemon over the top and sprinkle chopped parsley or chili flakes. Taste and adjust salt if needed. Serve hot.
