Equipment

Ingredients
  

  • 4-6 large Portobello mushrooms (depending on how many you can fit into your air fryer) cleaned with a damp paper towel
  • 1 Tbsp. Olive oil
  • ½ tsp. Sea salt
  • ½ tsp. Black pepper
  • 2 cloves Garlic minced
  • 1 tsp. Balsamic vinegar
  • ¼ tsp. Dried oregano
  • ¼ tsp. Dried thyme

Instructions
 

  • Clean the mushrooms with a damp paper towel or cloth, wiping off any dirt. Don't rinse the mushrooms under running water or in a bowl of water as they absorb water fast! Once the mushrooms are clean, cut out the thick stem.
    4-6 large Portobello mushrooms (depending on how many you can fit into your air fryer)
  • Whisk together the marinade ingredients in a small bowl.
    1 Tbsp. Olive oil, ½ tsp. Sea salt, ½ tsp. Black pepper, 2 cloves Garlic, 1 tsp. Balsamic vinegar, ¼ tsp. Dried oregano, ¼ tsp. Dried thyme
  • Brush the mushrooms on both sides with the marinade, leaving some marinade over at the end.
  • Place the mushrooms in the air fryer, tops down and gill side up. Pour the remaining marinade over the mushrooms. Air fry for 5 minutes at 400 °F (200 °C), then flip the mushrooms and air fry for another 4 - 7 minutes.
  • Allow mushrooms to cool for 2-3 minutes before serving.

Notes

Storage
Store any leftover mushrooms in the refrigerator in an airtight container for up to 3 days. You can eat them cold, straight from the refrigerator, or warm them up a bit in the microwave.
These mushrooms don't stand up well to freezing at all.
