Simple, yet crunchy and flavorful, these buttermilk fried oyster mushrooms are perfect for dinner. If you have any leftovers, these fried mushrooms can be stored for up to three days in the fridge. Ensure it's in an airtight container and when ready to reheat stick your battered mushrooms in the air-fryer for five to eight minutes or in the oven for eight to 15 minutes.
Ingredients
- 1 cup (250 ml) plant-based milk (such as oat or soy)
- 1 tbsp (15 ml) lemon juice
- 4 oz (114 g) oyster mushrooms cleaned and pulled apart into large chunks
- 1½ cups (375 ml) all-purpose flour
- 1½ tsp salt
- 1½ tsp paprika
- ¾ tsp black pepper
- 1 tsp garlic powder
- 1 tsp onion powder
- Cooking spray
Instructions
Oven method:
- Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly grease it.
- In a large bowl, mix the plant-based milk and lemon juice (this will result in vegan buttermilk). Add the oyster mushrooms and toss to evenly coat. Marinate in the buttermilk for 15 minutes, tossing halfway through. (The buttermilk may separate—this is totally OK. You can just whisk it back together if needed.)
- In another large bowl, whisk together the flour, salt, paprika, pepper, garlic powder, and onion powder.
- Take a mushroom from the buttermilk mixture and toss it in the flour mixture. Shake off the excess flour, then dunk it back into the buttermilk mixture, and then again in the flour mixture.
- Set aside on the prepared baking sheet in a single layer or on a plate if using the air fryer. repeat with the remaining mushrooms, giving each a double coating.
- Spray the mushrooms generously with cooking spray on all sides. Bake for 10 minutes, flip, spray the tops with more oil (making sure to coat any powdery spots), and continue to cook for another 8–15 minutes, until golden brown and crispy.
Air-fryer Method:
- Follow the same steps for preparing the oyster mushrooms as above but instead of using the oven, preheat your air-fryer to 370°F (188°C).
- Then, when your oyster mushrooms are ready, grease the bottom of the air-fryer basket. Lay the coated mushrooms in the basket in a single layer—do not overcrowd (you may need to work in batches).
- Spray the tops generously with cooking spray. Air-fry for 5 minutes, flip, spray with more oil (making sure to coat any powdery spots), and continue cooking for another 5–10 minutes, until golden brown and crispy.
