Can I use different types of mushrooms for this recipe?

Absolutely! While baby portobellos offer a meaty texture, white button mushrooms, cremini, or even a mushroom medley work beautifully. Just be aware that cooking times might vary slightly depending on the variety and thickness of your slices.

My mushrooms released a lot of liquid. Is that normal?

Yes, mushrooms naturally release moisture when cooking. If you find too much liquid, try not overcrowding your air fryer basket and make sure your air fryer is fully preheated. The high heat helps evaporate the moisture quickly, allowing for better caramelization.

Can I add fresh garlic instead of garlic powder?

Fresh garlic can burn easily at high temperatures. If you prefer fresh garlic, add it during the last 2-3 minutes of cooking time, or use larger pieces that won't burn as quickly. Alternatively, toss the finished mushrooms with minced garlic sautéed in butter for a fresh garlic flavor.

My air fryer is small. How should I adjust the recipe?

For smaller air fryers, cook in batches rather than crowding all the mushrooms at once. Each batch might cook a bit faster, so start checking at the 8-minute mark. Keep the first batches warm in a low oven while you finish the rest.

Ingredients You’ll Need

Sliced Mushrooms: Baby portobello mushrooms are my go-to for their meaty texture and rich flavor. Their natural umami really shines when air fried.
Olive Oil: Just enough to help the mushrooms crisp up nicely. The oil helps the seasonings stick and promotes browning.
Dried Oregano: Brings an earthy, slightly sweet herbaceous note that pairs beautifully with mushrooms.
Salt: Enhances all the flavors and helps draw out the natural moisture from the mushrooms.
Garlic Powder: Adds that savory depth that makes these mushrooms irresistible without the risk of burning that fresh garlic might have.
Black Pepper: Provides a subtle kick and balances the earthiness of the mushrooms.

Variations

Herb Combinations

Switch up the dried oregano for Italian seasoning, herbs de Provence, or rosemary for completely different flavor profiles.

Spicy Version

Add red pepper flakes or a dash of cayenne for heat-lovers.

Parmesan Mushrooms

Sprinkle freshly grated parmesan cheese over the mushrooms during the last 2 minutes of cooking.

Asian-Inspired

Replace oregano with a combination of ginger powder and a splash of soy sauce for an Asian twist.

How to Make Air Fryer Sliced Mushrooms

Step 1: Preheat Your Air Fryer

Preheat your air fryer to 400°F. This ensures your mushrooms start cooking immediately and develop those lovely crispy edges.

Step 2: Season the Mushrooms

In a medium bowl, combine the sliced mushrooms, olive oil, oregano, salt, garlic powder, and black pepper. Toss everything thoroughly to ensure each mushroom slice is evenly coated with oil and seasonings.

Step 3: Air Fry to Perfection

Spread the seasoned mushrooms in your preheated air fryer in a single layer if possible. Cook for 10 minutes, then check for doneness. If you prefer crispier mushrooms with more caramelization, cook for an additional 2-5 minutes.

Step 4: Serve

Transfer to a serving dish and enjoy while hot!

Pro Tips for Making the Recipe

Don’t Overcrowd: Work in batches if necessary. Overcrowding leads to steaming rather than caramelization.
Uniform Slices: Try to keep mushroom slices similar in thickness for even cooking.
Shake the Basket: Give the basket a good shake halfway through cooking for even browning.
Pat Dry First: If your mushrooms seem particularly wet, pat them dry with paper towels before seasoning to promote better browning.
Watch Closely at the End: The difference between perfectly caramelized and over-browned can happen quickly, so keep an eye on them during those final minutes.

How to Serve

As a Side Dish

These mushrooms are spectacular alongside a grilled steak, roast chicken, or pork chops.

With Pasta

Toss them into a simple garlic butter pasta for an elevated meal with minimal effort.

On Toast

Pile them high on toasted sourdough with a smear of ricotta for a delicious light lunch.

In Breakfast Dishes

Add to omelets, frittatas, or breakfast burritos for a flavor boost.

As an Appetizer

Serve with toothpicks and a dipping sauce for an easy appetizer that everyone will love.

Make Ahead and Storage

Storing Leftovers

Store cooled mushrooms in an airtight container in the refrigerator for up to 3 days. They’ll release some moisture during storage but will still taste delicious.

Freezing

While possible, freezing isn’t ideal as mushrooms can become watery when thawed. If you must freeze, use them in cooked dishes rather than as a standalone side after thawing.

Reheating

For best results, reheat in the air fryer at 350°F for 2-3 minutes to restore some of the crispiness. Microwave reheating works in a pinch but won’t revive the crispy texture.
