Keto Crispy Baked Portobello Mushrooms
These crispy baked portobello mushrooms feature a golden coating of almond flour, flaxseed meal, and Parmesan cheese that delivers satisfying crunch without traditional breadcrumbs. The meaty mushroom slices are dipped in egg then coated with a seasoned mixture of smoked paprika and garlic powder before baking to perfection. Perfect as an appetizer, side dish, or light main course, these mushrooms offer a healthier alternative to fried options while maintaining incredible flavor and texture. The almond flour coating creates a nutty, crispy exterior that pairs beautifully with the earthy mushrooms.

Tips
Mist the coated mushrooms with olive oil spray before baking to enhance the crisping process and achieve a golden exterior.
Make sure to remove both stems and dark gills from portobellos as the gills can make the coating soggy and muddy the appearance.
Let the mushrooms cool on a wire rack after baking to prevent the bottom from becoming soggy from trapped steam.
Good to Know
Refrigerate cooked mushrooms up to 3 days in airtight container. Reheat in oven at 180°C for 5-7 minutes to restore crispness.
Coat mushrooms up to 4 hours ahead and refrigerate on tray. Bake just before serving for best texture.
Serve immediately while hot and crispy with ranch dressing, aioli, or marinara sauce for dipping.
