Air Fryer Mushrooms

These Air Fryer Mushrooms cook up tender, savory, and lightly browned in about 10 minutes. I make them with roasted garlic butter for rich flavor, but the method is simple enough to use with your favorite mushrooms and seasonings.

These garlic butter air fryer mushrooms are one of my favorite quick sides when I want something savory that still feels like it belongs next to a good steak dinner. Serve them with Air Fryer Steak, pair them with Pan Seared Steak, or add them next to Mashed Cauliflower for a cozy plate.

Why You’ll Love These Air Fryer Mushrooms

• Quick side dish: The mushrooms cook in about 10 minutes, making them easy to add to dinner while the main dish comes together.
• Simple ingredients: You only need mushrooms, roasted garlic butter, and sea salt.
• Less stovetop mess: The air fryer keeps the mushrooms contained, so you get a savory side without managing another skillet.
• Easy to customize: Keep the roasted garlic butter, add Parmesan, swap the sea salt for steak seasoning, or use a different butter sauce.
• Great with proteins: These mushrooms work as a side dish or topping for steak, chicken, pork chops, and burgers.

Ingredients You’ll Need

• Mushrooms: I use baby bella mushrooms because they have a deeper, savory flavor and hold up well in the air fryer. Cremini, white button mushrooms, shiitake, or sliced portobello mushrooms can also work. Try to keep the pieces close in size so they cook evenly.
• Roasted Garlic Butter: Melt it first so it coats the mushrooms evenly and gives them rich flavor without extra prep.
• Sea salt: A small amount brings out the flavor of the mushrooms and balances the butter.

How to Make Air Fryer Mushrooms

Coat the Mushrooms

Add the mushrooms, melted roasted garlic butter, and sea salt to a large mixing bowl. Use a rubber spatula to toss everything together until the mushrooms are evenly coated.

Add Them to the Air Fryer

Place an air fryer parchment liner in the basket if needed. Add the mushrooms in a single layer so the hot air can move around them.

Air Fry Until Tender

Cook the mushrooms at 400°F for 10 minutes, stirring halfway through. They’re ready when they’re tender, lightly browned, and have released some of their moisture.

Tips for the Best Air Fryer Mushrooms

• Cut evenly: If some mushrooms are much larger than others, cut them in half so they cook at the same pace.
• Use a single layer: Crowding the basket can make the mushrooms steam instead of brown. If you’re doubling the recipe, cook them in batches.
• Stir halfway through: This helps the mushrooms cook evenly and keeps the butter distributed.
• Use liners if your basket sticks: I’ve tested these in a few air fryers. My Ninja Foodi has a nonstick surface, but if your basket tends to stick, use air fryer parchment paper or a light spray of oil.
• Expect some liquid: Mushrooms naturally release moisture as they cook. If you want less sauce on the plate, transfer them with a slotted spoon or blot lightly with paper towels.

Garlic Butter Mushroom Option

This recipe uses Roasted Garlic Butter as the main flavor, so the mushrooms already have that garlic-butter taste built in.

For a little more richness, spoon extra melted roasted garlic butter over the mushrooms after cooking. You can also use herb butter for steaks for a more classic steak dinner flavor.

More Ways to Season Air Fryer Mushrooms

This same air fryer method works with a few easy seasoning swaps. Keep the cook time the same and choose the option that best matches the rest of your meal.

• Garlic Parmesan mushrooms: Sprinkle grated Parmesan over the mushrooms after air frying while they’re still hot. It adds a salty, savory finish that works well with the roasted garlic butter.
• Steakhouse mushrooms: Use the roasted garlic butter as written, then replace the sea salt with a small amount of Steak Seasoning. This gives the mushrooms a bolder flavor for steak bites, burgers, pork chops, or roasted chicken.
• Cajun mushrooms: Swap the roasted garlic butter for olive oil or melted butter, then season the mushrooms with Homemade Cajun Seasoning before air frying. This gives them a bold, savory kick that works well with steak, shrimp, chicken, or pork chops.
• Lemon garlic mushrooms: Use Lemon Garlic Butter Sauce in place of the roasted garlic butter for a brighter option, especially with chicken, fish, or seafood.
• Basic garlic herb mushrooms: Swap the roasted garlic butter for olive oil, then season with garlic powder, onion powder, salt, pepper, and dried herbs.

What to Serve with Air Fryer Mushrooms

Air fryer mushrooms are especially good with steak because they add a savory side without needing a separate skillet. Serve them with Air Fryer Steak for a simple air fryer steak dinner, or pair them with Pan Seared Steak when you want a hot skillet sear.

They also work well with steak bites. For a full air fryer option, serve them with Air Fryer Steak Bites. For a stovetop option, pair them with Garlic Butter Steak Bites so the steak gets a quick skillet sear while the mushrooms finish in the air fryer.

They’re also great with Garlic Butter Pork Chops or Air Fryer Roasted Whole Chicken. For burger night, spoon them over Air Fryer Frozen Turkey Burgers or serve them on the side.

How to Store Leftovers

• Store leftover air fryer mushrooms in an airtight container in the refrigerator for up to 5 days.
• Reheat them in the air fryer for a few minutes until warm, or use a skillet if you want to cook off some of the extra moisture.
