Preheat your oven to 350°F (175°C) or your air fryer to 400°F (200°C).

Carefully clean and trim your mushrooms, opting for baby bella or button varieties for optimal taste and texture.

In a medium bowl, combine panko breadcrumbs with ranch seasoning to create a flavorful coating.

In a separate bowl, crack and beat your egg (or chosen egg substitute) until well blended.

Take each mushroom cap and dip it into the beaten egg, then roll in the breadcrumb mixture.

Place the coated mushrooms on a baking sheet lined with parchment or into the air fryer basket in a single layer.

Bake for 20 minutes or air fry for 10-12 minutes, flipping halfway through.

Serve immediately with your favorite dipping sauces.
