Ingredients

- 3 tablespoons unsalted butter, melted
- 4 cloves garlic, finely minced
- 1 tablespoon olive oil
- 1 teaspoon Italian seasoning
- ½ teaspoon onion powder
- ½ teaspoon smoked paprika
- ½ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- 1 tablespoon fresh parsley, finely chopped
- 1 teaspoon fresh thyme leaves (optional)
- 1 tablespoon grated Parmesan cheese (optional)
- Lemon wedges, for serving
Equipment Needed
- Air fryer
- Mixing bowl
- Measuring spoons
- Silicone spatula or spoon
- Serving platter
Instructions
Step 1: Clean the Mushrooms
Gently wipe the mushrooms with a damp paper towel to remove any dirt. Avoid soaking them in water because mushrooms absorb moisture easily, which can prevent proper browning. Trim the ends of the stems if needed while keeping the mushrooms whole.
Step 2: Prepare the Garlic Butter
In a medium mixing bowl, combine the melted butter, olive oil, minced garlic, Italian seasoning, onion powder, smoked paprika, salt, and black pepper. Stir until everything is well blended.
Step 3: Coat the Mushrooms
Add the cleaned mushrooms to the bowl and toss gently until every mushroom is evenly coated with the garlic butter mixture. This ensures every bite is packed with flavor.
Step 4: Preheat the Air Fryer
Preheat your air fryer to 380°F (193°C) for about 3 minutes. Preheating helps create even cooking and promotes caramelization.
Step 5: Arrange the Mushrooms
Place the mushrooms in a single layer inside the air fryer basket. Avoid overcrowding the basket because proper airflow is essential for even roasting. If necessary, cook in two batches.
Step 6: Air Fry
Cook at 380°F (193°C) for 10–12 minutes.
Shake the basket halfway through cooking to ensure all sides roast evenly. The mushrooms should become tender with golden brown edges while releasing their natural juices.
Step 7: Finish and Garnish
Transfer the mushrooms to a serving bowl. Sprinkle with chopped parsley, fresh thyme if using, and grated Parmesan cheese. Serve immediately with fresh lemon wedges for a bright finish.
Cooking Tips
- Choose mushrooms that are firm, dry, and free from blemishes.
- Cremini mushrooms offer a deeper flavor than white button mushrooms.
- Whole mushrooms retain more moisture and texture than sliced mushrooms.
- Do not overcrowd the air fryer basket, as this can cause steaming instead of roasting.
- Fresh garlic delivers the best flavor, but garlic powder can be substituted in a pinch.
- Add crushed red pepper flakes if you enjoy a little heat.
- For extra richness, stir in another teaspoon of melted butter just before serving.
Variations
Herb Butter Mushrooms
Replace Italian seasoning with fresh rosemary, thyme, and parsley for a more aromatic version.
Cheesy Mushrooms
Top the cooked mushrooms with shredded mozzarella or Parmesan and air fry for another minute until melted.
Balsamic Garlic Mushrooms
Add one tablespoon of balsamic vinegar to the garlic butter mixture before cooking for a sweet and tangy flavor.
Spicy Garlic Mushrooms
Mix in ½ teaspoon cayenne pepper or red pepper flakes to give the mushrooms a spicy kick.
Vegan Version
Replace butter with vegan butter or extra virgin olive oil while keeping the remaining ingredients the same.

Storage Instructions
Allow the mushrooms to cool completely before storing.
Refrigerate them in an airtight container for up to 4 days.
To reheat, place them back in the air fryer at 350°F (175°C) for 3–4 minutes until warmed through. You can also microwave them, though they will lose some of their crisp edges.
Freezing is not recommended because mushrooms tend to become watery after thawing.

Frequently Asked Questions
Can I use sliced mushrooms?
Yes. Reduce the cooking time to about 8–10 minutes since sliced mushrooms cook more quickly.
Which mushrooms work best?
Button, cremini, baby bella, and even small portobello mushrooms all work well in this recipe.
Can I make these ahead?
Yes. Cook them ahead of time and refrigerate. Reheat in the air fryer for the best texture.
Why are my mushrooms watery?
Mushrooms naturally release moisture during cooking. Avoid overcrowding the basket so the moisture can evaporate, allowing the mushrooms to roast rather than steam.
Can I double the recipe?
Absolutely. Cook the mushrooms in separate batches to maintain proper airflow and even browning.
