Air Fryer Garlic Butter Roasted Mushrooms
Some side dishes are so easy that you almost forget how delicious they can be.
These Air Fryer Garlic Butter Roasted Mushrooms are exactly that.
Fresh mushrooms are tossed in melted garlic butter, seasoned with herbs and black pepper, and air fried until they’re tender in the center with beautifully browned, slightly crispy edges.
I first made these on a weekend when I was preparing dinner and realized I had a container of mushrooms sitting in the refrigerator that needed to be used.
I didn’t want to make anything complicated.
So I melted some butter, added plenty of garlic, tossed in the mushrooms, and put everything into the air fryer.
A few minutes later, the kitchen smelled incredible.
The mushrooms came out golden and juicy, with that rich buttery garlic flavor I absolutely love.
I put them on the table as a side dish, expecting everyone to take a few.
Instead, they disappeared.
Someone actually asked if I had made another batch.
That’s when I knew these weren’t going to be an occasional side dish anymore.
Now I make them whenever I want something quick to serve alongside chicken, steak, seafood, or even a simple bowl of rice.

How to Make Air Fryer Garlic Butter Mushrooms
Step 1: Prepare the Mushrooms
Clean the mushrooms gently.
If they’re relatively clean, wipe them with a damp paper towel rather than soaking them.
Trim the ends of the stems.
You can leave small mushrooms whole or cut larger mushrooms in half.
Try to keep the pieces similar in size so they cook evenly.
Step 2: Make the Garlic Butter
In a small bowl, combine the melted butter, olive oil, minced garlic, Italian seasoning, salt, and black pepper.
Add red pepper flakes if you like a little heat.
Stir well.
Step 3: Coat the Mushrooms
Place the mushrooms in a large bowl.
Pour the garlic butter mixture over them.
Toss until every mushroom is lightly coated.
Don’t worry if some of the butter settles at the bottom—that’s normal.
Step 4: Preheat the Air Fryer
Preheat the air fryer to 200°C (400°F) for approximately 3 minutes.
Step 5: Air Fry
Place the mushrooms in the air fryer basket.
Try to arrange them in a single layer with a little space between them.
Air fry for approximately 10–14 minutes, shaking the basket halfway through.
The mushrooms should be tender and deeply golden around the edges.
If you prefer more browning, cook for another 2–3 minutes.
Step 6: Finish With Lemon and Herbs
Transfer the hot mushrooms to a serving bowl.
Squeeze fresh lemon juice over them.
Sprinkle with fresh parsley.
For an extra-rich finish, add a small spoonful of garlic butter while they’re still hot.
Serve immediately.
My Best Tips
Don’t Soak the Mushrooms
Mushrooms absorb water quickly. If they become waterlogged, they can steam instead of roast.
Don’t Overcrowd the Basket
Give the mushrooms enough space for hot air to circulate.
If necessary, cook in batches.
Use Fresh Garlic
Fresh garlic gives you the best flavor, especially when combined with butter.
Shake Halfway Through
This helps the mushrooms brown evenly.
Add Lemon at the End
The acidity brightens the rich butter and garlic and keeps the mushrooms from tasting too heavy.
Garlic Butter Mushroom Variations
Parmesan Garlic Mushrooms
Sprinkle grated Parmesan over the mushrooms during the final 1–2 minutes of cooking.
Spicy Garlic Mushrooms
Add red pepper flakes or cayenne.
Herb Butter Mushrooms
Use fresh thyme, rosemary, and parsley instead of dried Italian seasoning.
Balsamic Garlic Mushrooms
Add a small drizzle of balsamic glaze after air frying.
Steakhouse Mushrooms
Add a splash of Worcestershire sauce to the garlic butter and finish with fresh parsley.
Creamy Garlic Mushrooms
Air fry the mushrooms first, then toss them with a small amount of warm cream sauce.
What Mushrooms Work Best?
You can use:
- White button mushrooms
- Cremini mushrooms
- Baby bella mushrooms
- Portobello mushrooms
- A combination of mushrooms
Cremini or baby bella mushrooms are my favorite because they have a deeper, richer flavor.
What to Serve With Garlic Butter Mushrooms
These mushrooms are incredibly versatile.
Serve them with:
- Grilled steak
- Roast chicken
- Pork chops
- Garlic butter shrimp
- Baked salmon
- Burgers
- Mashed potatoes
- Rice
- Pasta
- Roasted vegetables
They’re also delicious piled onto toast for a quick snack.
Make-Ahead Instructions
You can clean and trim the mushrooms several hours ahead of time.
Prepare the garlic butter separately and refrigerate it.
Toss everything together just before air frying.
For the best texture, cook them immediately before serving.
Storage Instructions
Store leftover mushrooms in an airtight container in the refrigerator for up to 3 days.
Reheat them in the air fryer at 180°C (350°F) for a few minutes.
This helps bring back some of their roasted texture.
Can You Freeze Them?
I don’t recommend freezing these mushrooms.
Their texture can become soft and watery after thawing.
They’re best enjoyed fresh or refrigerated for a few days.

Frequently Asked Questions
Can I use frozen mushrooms?
Fresh mushrooms are strongly recommended because frozen mushrooms release more moisture and won’t brown as well.
Should I wash mushrooms before air frying?
You can quickly rinse them if needed, but dry them thoroughly. For lightly soiled mushrooms, wiping them with a damp towel is usually enough.
Why are my mushrooms watery?
They may have been overcrowded, too wet, or cooked at too low a temperature. Use a single layer and make sure the mushrooms are dry.
Can I use garlic powder instead of fresh garlic?
Yes, although fresh garlic provides a much stronger flavor. If using garlic powder, start with about 1 teaspoon.
Can I make these dairy-free?
Yes. Replace the butter with olive oil or your favorite dairy-free butter.
Can I make them spicy?
Absolutely. Add red pepper flakes, cayenne, or chili oil.
Can I add cheese?
Yes. Parmesan is especially delicious. Add it near the end so it melts and browns without burning.
Final Thoughts
These Air Fryer Garlic Butter Roasted Mushrooms are one of those little recipes that prove you don’t need complicated ingredients to make something memorable.
The mushrooms become beautifully golden on the outside while staying tender and juicy inside. The garlic and butter soak into every little crevice, while lemon and fresh parsley add just enough brightness.
I love making these when I’m cooking steak or chicken, but honestly, I’ve been known to eat them straight from the basket.
They’re that good.
And if you happen to have some crusty bread nearby, don’t waste that garlic butter left in the bottom of the bowl.
Dip, scoop, and enjoy every last bit. 🍄🧄🧈
