These air fryer portobello mushrooms with balsamic marinade are one of my favorite vegan recipes - so easy to make and full of flavor.
What are portobellos
Portobellos are edible mushrooms native to Europe and North America. Portobello mushrooms come in 3 sizes by age. From small to large: button mushrooms, cremini mushrooms, and portobello.
All three are the same type of mushroom, just harvested at different ages. Button mushrooms (baby bella) are white. Cremini and portobello are usually brown.
Portobello mushrooms have a meaty texture and earthy flavor. They are low in calories and are a great source of vitamin B2, selenium, and dietary fiber.
The stems and gills of portobello mushrooms are edible, but, many prefer to remove them because they tend to have a woody texture. You can use them to make some stock.
Mushroom lovers can follow this recipe to make all three types of portobellos Today, I am cooking large portobello mushrooms with a simple marinade which are great for burgers, sandwiches, or as a side dish.

See the recipe card for ingredient quantities.
- Clean the Mushrooms - First thing, use a damp cloth or a damp paper towel to wipe the mushrooms carefully to get rid of any dirt. If your mushrooms look too dirty, briefly rinse them under cold water. Remove the stems and the dark gills (optional)
Note: do not keep mushrooms under water for too long and do not soak them in water. They will absorb the water and the texture will be different after cooking. You can keep the stems and gills. The whole mushroom is edible.
Below you can see how I removed the gills off one of the mushrooms. I cooked the other two mushrooms with the gills. It's totally up to your personal preference.
- Prepare Marinade - in a small bowl, add olive oil, balsamic vinegar, soy sauce, pepper, and garlic powder. Whisk everything well until combined.
Note: I like to use only few simple spices for the marinade. You can add fresh herbs such as rosemary, basil, or some Italian seasoning to the marinade.
- Quick Marinate - pour the marinade into a shallow dish. Place clean mushrooms with the caps down into the dish and pour some extra marinade on top. Marinate for 5 minutes and flip them on the other side for another 5 minutes.
Note: instead of marinating, use a basting brush to apply the marinade on both sides of the mushroom. Let it sit for 5 minutes before cooking to absorb the flavors.
- Air Fry - preheat the air fryer for 5 minutes at 390°F. Remove the air fryer basket and place mushrooms in a single layer with the caps down first. Cook for 4 minutes at 390°F. Flip the mushrooms and cook for another 4-5 minutes or until they are soft and jucy inside and browned on the outside. Carefully remove the mushrooms and enjoy!
Note: cooking time may differ depending on the type of air fryer and thickness of the mushrooms.
- Side Dish: enjoy sliced portobello mushroom as a side dish to company pasta, eggs, and french fries.
- Portobello Burger: portobello mushrooms have a meat-like texture and make excellent vegetarian burgers.
- Ciabatta Sandwich: my favorite one is the sandwich with a cooked mushroom, goat cheese, and arugula on a slice of toasted ciabatta bread.
Tips for success
- clean the mushrooms with a damp paper towel or cloth.
- you do not have to remove the gills.
- let the mushrooms marinate for 5 minutes.
- cooking times and temperatures may vary depending on the air fryer type.
How to store and reheat
Transfer any leftovers to an airtight container and store them in the fridge for up to 3 days.
I do not recommend freezing whole mushrooms caps.You can freeze chopped mushrooms to use for the saute later.
The best way to reheat the cooked mushrooms without drying them out is in the microwave oven for about 1 minute. You can also reheat them in the air fryer at 350°F for about 3 minutes or until hot.
Do I need to remove the gills of a portobello mushroom?
No, you don't. Both gills and stems are edible. Some people prefer to remove them because they do not like how they look and taste. Gills and stems might taste too woody and release liquid. If you remove stems and gills, use them to make some stock.
How to store fresh portobello mushrooms?
All fresh mushrooms should be stored in the fridge in thin the ordinal package or a paper bag for up to one week. Do not freeze fresh mushrooms.
Can I make this recipe without an air fryer?
Yes, you can grill or fry the mushrooms on a pan using the same marinade.
