Ingredients
For the Mushrooms
- 1 pound (450 g) fresh mushrooms
- 3 tablespoons unsalted butter, melted
- 1 tablespoon olive oil
- 3 cloves fresh garlic, finely minced
- ½ teaspoon salt
- ¼ teaspoon freshly ground black pepper
- ½ teaspoon Italian seasoning
- ½ teaspoon paprika
- 1 tablespoon fresh parsley, finely chopped
- 1 teaspoon fresh lemon juice, optional
- 1 tablespoon grated Parmesan cheese, optional
Choosing the Best Mushrooms
The type of mushroom you use can slightly change the flavor and texture of the finished dish.
White button mushrooms are mild, tender, and easy to find. They are an excellent choice for this recipe.
Cremini mushrooms, sometimes called baby bella mushrooms, have a deeper and more savory flavor. They also hold their texture particularly well during cooking.
You can also use larger mushrooms, but they should be cut into halves or quarters so that they cook evenly.
When choosing mushrooms, look for ones that are firm and fresh. Avoid mushrooms that are extremely soft, slimy, or have obvious signs of spoilage.
How to Clean Mushrooms
Mushrooms can hold dirt around their stems, so they should be cleaned before cooking.
You can gently wipe them with a damp paper towel to remove visible dirt. Alternatively, you can rinse them briefly under cool water and then dry them extremely well.
The important part is making sure the mushrooms are dry before seasoning them.
Mushrooms naturally contain a lot of water. If they are very wet when they enter the air fryer, they may steam instead of browning.
Step 1: Prepare the Mushrooms
Begin by cleaning the mushrooms thoroughly.
Trim the very end of the stems if needed. There is no need to remove the entire stem because it is edible.
If your mushrooms are small, you can leave them whole.
For medium or large mushrooms, cut them in half. Very large mushrooms can be quartered.
Try to cut them into similarly sized pieces. This helps everything cook at approximately the same rate.
Once prepared, place the mushrooms into a large mixing bowl.
Step 2: Prepare the Garlic Butter
Melt the butter in a small bowl.
Add the olive oil and finely minced garlic.
Next, add the salt, black pepper, Italian seasoning, and paprika.
Mix everything together thoroughly.
The butter provides richness, while olive oil helps the mushrooms brown nicely. Garlic gives the dish its main savory flavor, while Italian seasoning adds a delicious herbal note.
Paprika is optional, but it adds a subtle warmth and attractive color.
Step 3: Coat the Mushrooms
Pour the garlic butter mixture over the mushrooms.
Use a spoon or clean hands to gently toss the mushrooms until they are evenly coated.
Make sure the garlic and seasonings are distributed throughout the bowl.
You don’t need to let the mushrooms marinate for a long time. In fact, they can go directly into the air fryer once coated.
If you let them sit for too long, the salt can begin drawing moisture from the mushrooms, which may affect browning.
Step 4: Preheat the Air Fryer
Preheat your air fryer to 375°F (190°C) for approximately 3 minutes.
Some air fryers do not require preheating, but preheating can help the mushrooms begin browning more quickly.
If your particular air fryer manufacturer’s instructions recommend a different approach, follow those instructions.
Step 5: Arrange the Mushrooms
Place the seasoned mushrooms into the air fryer basket.
Try to arrange them in a relatively even layer.
Avoid packing the basket too tightly.
This is one of the most important tips for getting nicely browned mushrooms. Air fryers work by circulating hot air around the food. If the mushrooms are piled on top of one another, the air cannot circulate effectively.
If you have a small air fryer, cook the mushrooms in batches rather than overcrowding the basket.
Step 6: Air Fry the Mushrooms
Cook the mushrooms at 375°F (190°C) for approximately 10–14 minutes.
After about 5–7 minutes, carefully shake the basket.
Shaking helps turn the mushrooms and allows different sides to come into contact with the hot circulating air.
Continue cooking until the mushrooms are tender and browned around the edges.
The exact cooking time can vary depending on:
- The size of the mushrooms
- Whether they are whole or sliced
- How crowded the basket is
- The type of air fryer you have
- How browned you prefer them
Start checking around the 10-minute mark.
If you prefer deeper browning, continue cooking for another 2–3 minutes.
Step 7: Finish the Mushrooms
Once the mushrooms are cooked, carefully transfer them to a serving bowl.
Sprinkle over the freshly chopped parsley.
If you are using Parmesan cheese, add it while the mushrooms are still hot so it can lightly melt over the surface.
For a fresh finishing touch, add about 1 teaspoon of lemon juice.
The lemon is optional, but it helps balance the richness of the butter and makes the garlic flavor taste brighter.
Give everything one gentle toss.
Important Tips for Perfect Mushrooms
Don’t Overcrowd the Basket
This is perhaps the most important tip.
Mushrooms naturally release moisture while cooking. If the basket is overcrowded, that moisture can create steam and prevent the mushrooms from browning properly.
Give them enough room for the hot air to circulate.
Dry the Mushrooms Thoroughly
Whether you wipe or rinse your mushrooms, make sure they are dry before adding the garlic butter.
Extra water can make them softer and reduce browning.
Use Fresh Garlic
Freshly minced garlic provides a much stronger and more delicious flavor than garlic powder.
However, garlic can brown quickly in an air fryer, so keep an eye on the mushrooms during the final minutes.
Don’t Use Too Much Butter
Butter adds wonderful flavor, but you don’t need to completely soak the mushrooms.
A moderate amount of butter is enough to coat them and provide richness.
Shake Halfway Through Cooking
Shaking the basket halfway through cooking helps promote more even browning.
For especially large mushroom pieces, you can gently turn them with tongs instead.
Flavor Variations
Spicy Garlic Butter Mushrooms
For a spicy version, add a small pinch of red pepper flakes or cayenne pepper to the butter mixture.
Parmesan Garlic Mushrooms
Add grated Parmesan after air frying. For an extra cheesy finish, return the mushrooms to the air fryer for about 1 minute.
Lemon Herb Mushrooms
Add fresh lemon zest and extra chopped parsley. You can also add fresh thyme for an aromatic flavor.
Rosemary Garlic Mushrooms
Replace the Italian seasoning with finely chopped fresh rosemary. Rosemary pairs especially well with steak and roasted potatoes.
Creamy Mushroom Topping
Prepare the mushrooms as directed, then serve them over grilled chicken, steak, baked potatoes, or toasted bread with a spoonful of your favorite creamy sauce.
What to Serve With Garlic Butter Mushrooms
These mushrooms can accompany almost any main course.
Serve them with:
- Grilled steak
- Roast chicken
- Baked chicken
- Grilled fish
- Burgers
- Meatloaf
- Pasta
- Mashed potatoes
- Roasted potatoes
- Rice
- Scrambled eggs
- Omelets
- Toasted bread
- Sandwiches
- Grilled vegetables
They also make an excellent addition to a holiday dinner table.
How to Store Leftovers
If you have leftovers, allow the mushrooms to cool before placing them in an airtight container.
Store them in the refrigerator and use them within about 3 days for the best quality.
Keep in mind that mushrooms can soften after refrigeration, but reheating them in the air fryer can help bring back some of their roasted texture.
How to Reheat
Place the leftover mushrooms in the air fryer at approximately 350°F (175°C).
Heat them for about 3–5 minutes, checking frequently.
Avoid cooking them for too long because they can become dry or chewy.
You can also reheat them briefly in a skillet over medium heat.
Can You Make These Ahead of Time?
You can clean and prepare the mushrooms ahead of time, but they are best cooked shortly before serving.
For the freshest texture, prepare the garlic butter mixture and mushrooms separately and combine them shortly before air frying.
This helps prevent the mushrooms from sitting in seasoning and releasing too much moisture.
Frequently Asked Questions
Can I use frozen mushrooms?
Fresh mushrooms are recommended because they generally provide better texture and browning. Frozen mushrooms contain additional moisture and may not become as nicely roasted.
Can I use sliced mushrooms?
Yes. Sliced mushrooms work well, but they may cook faster than whole or halved mushrooms. Start checking them earlier.
Can I leave the mushrooms whole?
Yes, especially if they are small. Whole mushrooms may require slightly more cooking time than sliced mushrooms.
Do I need to use olive oil?
Not necessarily. Butter alone can work, but a small amount of olive oil can help with browning and provides a slightly lighter coating.
Can I make this recipe dairy-free?
Yes. Replace the butter with a dairy-free butter alternative or use additional olive oil. Skip the Parmesan if necessary.
Serving Idea
For a simple dinner, serve these mushrooms alongside grilled chicken, roasted potatoes, and a fresh salad.
For a steak dinner, spoon the hot garlic butter mushrooms directly over the steak and finish with fresh parsley.
For a quick lunch, pile them onto toasted bread and sprinkle with Parmesan.
You can even mix the finished mushrooms into cooked pasta for a simple garlic mushroom pasta.
