Preheat oven to 400 F. Remove the stems from the mushrooms and wash well. Use your hands or a brush to really scrub any excess dirt from each one. Pat dry and place on a baking sheet with parchment paper for easy clean up. Leave about 1 inch in between each mushroom.
24 oz package mushrooms
In a bowl, combine the almond flour, nutritional yeast, garlic powder, and sea salt. Remove the leaves from the rosemary stems over the bowl as well then toss to combine. You can use your hands to do this or a fork. Set the bowl aside.
½ cup almond flour, 1 tablespoon nutritional yeast, 1 teaspoon garlic powder, ½ teaspoon sea salt
Cut the feta block into ½ inch pieces and place one inside the center of each mushroom. You want to stuff the center full with feta so if there is a piece that is too small, add another little sliver of feta to fill the center.
6 oz block of feta cheese
Drizzle olive oil over each mushroom. You can do this with an olive oil dispenser and drizzle over the baking sheet or use a spoon and sprinkle ½ - 1 teaspoons of olive over each mushroom. This is important as this helps to keep the mushrooms moist and soft in the oven and is how the “bread crumbs” stick to the mushrooms.
3 rosemary stems, Olive oil
Use your hands or a spoon to sprinkle the “bread crumbs” over the mushrooms. Bake in the oven for 14 - 16 minutes until the feta is starting to turn golden and the “bread crumbs” are toasted. Serve warm and enjoy!
