Ingredients
- 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

- Step 1: Rinse the portobello mushroom caps under cold water and pat them dry thoroughly with paper towels.
- Step 2: In a small bowl, mix the Worcestershire sauce, olive oil, garlic powder, onion powder, and salt until combined.
- Step 3: Lightly spray the air fryer basket with olive oil to prevent sticking.

- Check mushrooms at 4 minutes for doneness to avoid overcooking, as air fryer times can vary.
