Ingredients
Marinade & Mushrooms
- 2 small/medium whole portobello mushroom caps
- 1 ½ tablespoons Worcestershire sauce
- 1 tablespoon olive oil
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
- ¼ teaspoon salt
- Olive oil spray (for air fryer basket)
Instructions
- Prepare the Mushrooms: Rinse the portobello mushroom caps thoroughly under cold running water to remove any dirt. Pat them dry completely with paper towels to ensure they absorb the marinade well and cook properly.
- Make the Marinade: In a small bowl, combine Worcestershire sauce, olive oil, garlic powder, onion powder, and salt. Stir these ingredients together until fully blended, creating a flavorful marinade for the mushrooms.
- Prepare Air Fryer Basket: Lightly spray the air fryer basket with olive oil spray to prevent the mushrooms from sticking and to assist in even cooking.
- Coat the Mushrooms: Using a basting brush, generously spread the marinade over the outside surface of each portobello mushroom cap. Place the mushrooms gill side up in the air fryer basket and brush the remaining marinade on top of the gill side to ensure full flavor coverage.
- Air Fry Mushrooms: Set the air fryer to 400°F (204°C) and cook the mushrooms for 5 minutes. After 5 minutes, flip the mushrooms over so the gill side is down and continue to air fry for an additional 4 to 7 minutes until the mushrooms are nicely browned and tender to the touch.
Notes
- If using larger portobello caps, increase cooking time slightly to ensure they cook through.
- Worcestershire sauce contains anchovies, so it is not suitable for strict vegetarians or vegans; substitute with a vegan Worcestershire alternative if needed.
- Allow mushrooms to cool slightly before serving; they can be served as a side dish, on sandwiches, or chopped into salads.
- Use a silicone basting brush for easy application and cleaning.
- The air fryer temperature and time may vary slightly depending on your air fryer model; monitor the mushrooms towards the end to avoid overcooking.
