Garlic Butter Air Fryer Mushrooms

There are some side dishes that are so easy, you almost wonder how something this simple can taste so good.

These Garlic Butter Air Fryer Mushrooms are one of those recipes.

The mushrooms become wonderfully tender inside while the edges get lightly browned and caramelized. Then they’re tossed in warm garlic butter and finished with fresh parsley.

It’s simple.

It’s savory.

And the smell when that garlic butter hits the hot mushrooms is absolutely irresistible.

I made these one evening when I was cooking steak for my family and realized I wanted something extra for the side.

I had a container of mushrooms in the refrigerator, so instead of sautéing them on the stovetop, I decided to throw them into the air fryer.

I tossed them with olive oil, a little soy sauce, and black pepper and let the air fryer do its thing.

A few minutes later, I melted some garlic butter and tossed it with the hot mushrooms.

That was it.

But when I brought them to the table, everyone kept reaching for them.

They were especially good alongside steak, but honestly, I could have eaten the entire bowl by itself.

Since then, these have become one of those recipes I make whenever I need a quick side dish. They’re especially handy on busy weeknights because they require very little preparation and cook in just minutes.

The original recipe also recommends keeping the mushrooms in a single layer and cooking them in batches if necessary, which helps them brown instead of steam.

What Kind of Mushrooms Should I Use?

Cremini or baby bella mushrooms give you a slightly deeper, earthier flavor, while white mushrooms have a milder taste.

How to Make Garlic Butter Air Fryer Mushrooms

1. Clean the Mushrooms

Gently wipe the mushrooms with a damp paper towel to remove any dirt.

Avoid soaking them in water.

Mushrooms absorb moisture quickly, and excess water can make it harder to get those beautifully browned edges.

If your mushrooms are large, cut them in half or into quarters.

Try to keep the pieces relatively similar in size so they cook evenly.

2. Preheat the Air Fryer

Preheat your air fryer to 400°F (200°C).

Allow it to heat for a few minutes before adding the mushrooms.

The hot basket helps the mushrooms start browning immediately.

3. Season the Mushrooms

Place the mushrooms in a large bowl.

Add the olive oil, soy sauce, and black pepper.

Toss well until all the mushrooms are lightly coated.

You don’t need a lot of seasoning because the garlic butter will add plenty of flavor at the end.

4. Air Fry

Place the mushrooms into the air fryer basket in a single layer.

Cook at 400°F (200°C) for approximately 6–8 minutes, shaking the basket halfway through.

The exact cooking time can vary depending on the size of your mushrooms and the type of air fryer.

For deeper browning, cook for another 1–2 minutes if needed.

The original recipe uses 6–8 minutes at 400°F and recommends shaking halfway through for even browning.

5. Make the Garlic Butter

While the mushrooms are cooking, melt the butter in a small saucepan or microwave-safe bowl.

Add the minced garlic.

If using a saucepan, warm the mixture gently for about 30–60 seconds.

You want the garlic fragrant, not browned.

6. Toss With Garlic Butter

Transfer the hot mushrooms to a serving bowl.

Pour the garlic butter over them.

Toss gently until every mushroom is coated.

7. Add Fresh Herbs

Sprinkle the mushrooms with freshly chopped parsley.

If you’d like, add a little fresh thyme or rosemary too.

Finish with a squeeze of lemon juice for a bright contrast to the buttery flavor.

8. Serve Immediately

These mushrooms are best served warm.

Bring them to the table alongside steak, chicken, pork, burgers, grilled vegetables, or simply enjoy them as a savory snack.

My Best Tips

Don’t Wash the Mushrooms Under Running Water

A quick rinse isn’t necessarily disastrous, but mushrooms can absorb water.

For the best air-fried texture, gently wipe them clean with a damp paper towel.

Don’t Crowd the Basket

This is probably the biggest secret to nicely browned mushrooms.

If you pile too many into the basket, they’ll release moisture and steam.

Cook in batches if necessary.

Cut Large Mushrooms

Very large mushrooms should be halved or quartered.

This helps them cook evenly and makes them easier to eat.

Add the Garlic Butter at the End

Garlic can burn quickly at high temperatures.

Adding the garlic butter after air frying gives you a much fresher garlic flavor.

Serve Immediately

Mushrooms are at their best when they’re hot and freshly coated in butter.

Can I Use Baby Bella Mushrooms?

Absolutely.

Baby bella mushrooms are one of my favorite choices for this recipe.

They have a deeper flavor and hold their texture nicely.

Can I Use White Button Mushrooms?

Yes.

They’re mild, inexpensive, and perfect for soaking up the garlic butter.

Can I Use Portobello Mushrooms?

Yes.

Cut them into smaller pieces before air frying.

Large portobello caps can also be cooked whole, but they’ll need additional cooking time.

Can I Use Mixed Mushrooms?

Definitely.

Try a combination of:

• Cremini
• Shiitake
• Oyster mushrooms
• White button
• Baby bella

Different mushrooms bring different textures and flavors.

Can I Use Garlic Powder Instead of Fresh Garlic?

Yes.

Fresh garlic gives the best flavor, but garlic powder is convenient.

Use approximately ½ teaspoon to start.

Can I Add More Garlic?

Absolutely.

If you’re a serious garlic lover, use 3–4 cloves.

There’s really no such thing as too much garlic butter in my kitchen.

Can I Add Parmesan?

Yes.

Sprinkle grated Parmesan over the hot mushrooms immediately after tossing them with garlic butter.

The cheese will cling beautifully to the warm mushrooms.

Can I Add Lemon?

Definitely.

A small squeeze of fresh lemon juice at the end brightens the entire dish.

It helps balance the richness of the butter.

Can I Make Them Spicy?

Yes.

Add:

• Red pepper flakes
• Cayenne pepper
• Chili powder
• Fresh chili
• Smoked paprika

Even a small pinch can add a nice kick.

Can I Add Herbs?

Absolutely.

Try:

• Parsley
• Thyme
• Rosemary
• Chives
• Oregano
• Tarragon

Parsley and thyme are especially delicious with garlic butter mushrooms.

Can I Use Ghee?

Yes.

Ghee works very well and gives the mushrooms a rich buttery flavor.

Can I Use Olive Oil Instead of Butter?

Yes, but you’ll lose some of that classic garlic-butter flavor.

For the best result, I recommend olive oil for the initial seasoning and butter for the finishing sauce.

Can I Make These Dairy-Free?

Yes.

Replace the butter with dairy-free butter or additional olive oil.

The mushrooms will still be delicious.

Can I Make These Gluten-Free?

Yes.

Use gluten-free tamari instead of regular soy sauce.

Always check your packaged ingredients if cooking for someone with celiac disease or a serious gluten intolerance.

Are These Keto-Friendly?

Yes.

Mushrooms are relatively low in carbohydrates, and the remaining ingredients contain very little carbohydrate.

For strict keto tracking, calculate the nutrition using the exact ingredients and brands you use.

Can I Make Them Without Soy Sauce?

Absolutely.

Replace it with:

• Coconut aminos
• Worcestershire sauce
• A pinch of salt
• Tamari

You can also simply leave it out.

Can I Use Worcestershire Sauce?

Yes.

Worcestershire sauce adds a wonderful savory depth.

Use a small amount because it has a strong flavor.

Can I Add Bacon?

Absolutely.

Crispy bacon and garlic butter mushrooms are an incredible combination.

Cook the bacon separately, crumble it, and sprinkle it over the finished mushrooms.

Can I Add Cheese?

Yes.

Try:

• Parmesan
• Asiago
• Gruyère
• Mozzarella
• Blue cheese

A little blue cheese is especially good with mushrooms served alongside steak.

Can I Put These on Steak?

Yes—and this is one of my favorite ways to serve them.

Spoon the garlic butter mushrooms directly over a freshly cooked ribeye or sirloin.

The juices from the steak and buttery mushrooms are fantastic together.

Can I Add Them to Burgers?

Definitely.

Pile the mushrooms onto a burger with Swiss cheese, caramelized onions, and a little garlic aioli.

Can I Add Them to Pasta?

Yes.

Toss them with cooked pasta, Parmesan, and a little of the garlic butter.

For a low-carb option, use zucchini noodles or shirataki noodles.

Can I Serve Them as an Appetizer?

Absolutely.

Place the warm mushrooms in a bowl with toothpicks and serve them as a simple party appetizer.

Can I Make Stuffed Mushrooms With This Recipe?

Yes.

Use larger mushroom caps and fill them with garlic butter, Parmesan, herbs, and perhaps crispy bacon.

Air fry until tender and golden.

Can I Add Onions?

Definitely.

Thinly sliced onions can be air fried with the mushrooms, although you may need to adjust the cooking time.

Can I Add Bell Peppers?

Yes.

Sliced peppers add sweetness and color.

Keep the pieces fairly thin so they cook at the same rate as the mushrooms.

Can I Add Zucchini?

Yes.

Use thick slices or half-moons.

Avoid cutting them too thin because they can become soft quickly.

Can I Add Broccoli?

Absolutely.

Small broccoli florets are delicious with garlic butter.

You may need to cook them slightly longer than the mushrooms.

Can I Use Frozen Mushrooms?

Fresh mushrooms are strongly recommended.

Frozen mushrooms contain more moisture and may not brown as nicely.

Can I Prepare the Mushrooms Ahead?

Yes.

Clean and cut the mushrooms several hours ahead.

Store them covered in the refrigerator.

Season and air fry just before serving for the best texture.

Can I Make These Ahead?

You can, although they’re best fresh.

If you need to make them ahead, refrigerate the cooked mushrooms and reheat them in the air fryer.

How Do I Reheat Air Fryer Mushrooms?

Place them back in the air fryer at approximately 350–375°F (175–190°C) for a few minutes.

Shake the basket once during reheating.

Avoid overheating because mushrooms can become chewy.

How Long Do They Last in the Refrigerator?

Store leftovers in an airtight container in the refrigerator.

For best quality, use within approximately 3–4 days.

Can I Freeze Garlic Butter Mushrooms?

You can, but freezing changes the texture.

Mushrooms tend to become softer after thawing.

For the best texture, make only as much as you plan to eat.

Frequently Asked Questions

Why are my mushrooms soggy?

The basket may have been overcrowded.

Mushrooms release moisture as they cook, so they need enough space for that moisture to evaporate.

Why aren’t my mushrooms browning?

Make sure the air fryer is fully preheated and the mushrooms are not wet.

Also avoid overcrowding.

Why did my garlic burn?

Garlic burns quickly at high temperatures.

That’s why I prefer adding the garlic butter after the mushrooms are finished cooking.

Do I need to shake the basket?

Yes.

A shake halfway through cooking helps expose different sides of the mushrooms to the hot air and encourages more even browning.

Can I cook them longer?

Yes.

If you prefer more browned edges, add another 1–3 minutes.

Keep an eye on them because cooking times vary between air fryer models.

Should I cut the mushrooms?

If they’re large, yes.

Small mushrooms can be left whole.

Can I use whole mushrooms?

Absolutely.

Whole small mushrooms are delicious, although they may need a little additional cooking time.

Why did my mushrooms shrink?

That’s completely normal.

Mushrooms contain a lot of water, which evaporates during cooking.

Can I cook these in the oven?

Yes.

Spread the mushrooms on a baking sheet and roast at approximately 425°F (220°C) until browned and tender.

Can I sauté them instead?

Definitely.

Cook them in a hot skillet until browned, then toss them with garlic butter.

Can I double the recipe?

Yes, but you may need to cook in batches.

Don’t sacrifice basket space just to fit everything in at once.
