Preheat the oven to 425°F and grease a large baking sheet.
Combine all the dipping sauce ingredients in a small bowl. Refrigerate until ready to use.
Mix the panko bread crumbs and grated parmesan in a small bowl.
In a separate bowl, whisk the almond milk, flour, garlic, onion powder, salt, pepper, and cayenne pepper together.
Dip each mushroom into the batter, then dredge through the panko mixture.
Arrange the breaded mushrooms in a single layer on the prepared baking sheet.
Bake for 20 minutes or until golden and crispy.
Serve with the dipping sauce. Enjoy!
Notes
Wipe the mushrooms with a damp paper towel to clean them. Then, dry them thoroughly; no one wants soggy mushrooms!
Adjust the amount of cayenne pepper to your liking. You can also add chili flakes to the dip.
Feel free to leave the vegan breaded mushrooms in the oven a bit longer if you like them extra crispy. But for softer mushrooms, take them out at the 15 or 18-minute mark.
