Air fryer Portobello mushroom burger

The air fryer is truly becoming a game-changer in my kitchen, I’ve used it to make everything from french fries to roasting asparagus, and each time it brings a new level of delight. It makes cooking healthier, faster, and more enjoyable.

Recently, I decided to incorporate more plant-based meals into my diet, and I stumbled upon the idea of making a Portobello mushroom burger. To my delight, I discovered that it turned out perfect in the air fryer.

Portobello mushrooms have a rich, umami flavor and a meaty texture that makes them a perfect substitute for traditional beef burgers. When cooked in an air fryer, they develop a crispy exterior while remaining juicy and tender on the inside. Even cooking ensures that the mushrooms are neither too dry nor too soggy, which can sometimes be a challenge with other cooking methods.

How to Air Fryer Portobello Mushroom Burger

Follow these simple steps to make the perfect air fryer Portobello mushroom burger.

Time needed: 1 hour and 7 minutes

  1. Prepare the Mushrooms

    Remove the stems of each Portobello mushroom. Using a spoon, scrape away the black gills from the underside of the mushrooms. This helps to reduce moisture and prevents a muddy flavor.

  2. Season the Mushrooms

    Place the cleaned mushrooms in a large bowl. Add the chopped thyme, garlic, Worcestershire sauce, olive oil, salt, and freshly cracked black pepper. Massage the herbs and oil into the mushrooms until they are evenly coated.

  3. Prepare the Cabbage Slaw (Optional)

    In a mixing bowl, combine 3/4 tsp honey, 4 tsp apple cider vinegar, 6 tbsp mayonnaise, 2 tsp whole grain mustard, 1/4 tsp kosher salt, and 15 turns of freshly cracked black pepper. Mix until well combined. Add 2 cups of thinly sliced green cabbage and 2 thinly sliced scallions to the bowl. Toss everything together until the cabbage is well coated with the dressing. Set aside.

  4. Preheat the Air Fryer

    Preheat your air fryer to 400°F (205°C) for about 5 minutes. (Note: The temperature may vary depending on the air fryer you are using. For this recipe, I am using the Typhur Dome air fryer.)typhur dome air fryer

  5. Cook the Mushrooms

    After preheating, carefully place the mushrooms with the stem side facing up in the cooking tray. Return the tray to the air fryer. Cook the mushrooms for 6 minutes at 400°F (205°C).

  6. Add Cheese

    Using a spatula, gently flip each mushroom. Place a slice of Swiss cheese on each mushroom and return the cooking tray to cook for an additional 1 minute, allowing the cheese to melt.

  7. Assemble the Burger

    Using a spatula, carefully remove the mushrooms from the air fryer. Place each mushroom on a toasted hamburger bun.

  8. Serve

    Top the mushrooms with the prepared cabbage slaw (if using). Place the top half of the toasted hamburger bun on each mushroom.

Portobello mushroom burger FAQs

Are mushroom burgers healthy?

Yes, mushroom burgers are a healthy alternative to traditional meat burgers. Portobello mushrooms are low in calories, fat, and cholesterol while being rich in vitamins and minerals, such as B vitamins, potassium, and antioxidants. They also provide fiber, which is beneficial for digestive health.

Do you scrape the inside of a portobello mushroom?

Scraping the inside of a Portobello mushroom is a matter of personal preference. The gills (the dark, feathery part underneath the cap) are edible and safe to eat. However, some people prefer to remove them for a few reasons:
Appearance: The gills can darken the dish and release a black liquid that might affect the appearance of your meal.
Texture: Removing the gills can result in a slightly cleaner texture.
Flavor: Some find the gills to have a slightly more earthy or muddy taste.
To scrape out the gills, use a spoon to gently scrape them out from underneath the mushroom cap.

How do I make my portobello not soggy?

When using the air fryer, make sure to cook the mushrooms at a high enough temperature (around 400°F/205°C) to allow them to cook through without becoming soggy. Cook them gill side down first to let any excess liquid drain out, then flip them halfway through cooking. After cooking, let the mushrooms rest on a paper towel or a rack for a few minutes to allow any remaining moisture to drain away.
