How this Recipe Comes Together

The steps to preparing these stuffed mushrooms are straightforward. First, the portobello caps are prepped and baked to create a sturdy base. Then, while they soften in the oven, the egg substitute is cooked along with fresh spinach, cottage cheese, and seasonings for added flavor and creaminess. The result is a delightful filling that’s scooped into the baked mushroom caps, topped with Parmesan cheese, and broiled until golden.

Directions to Follow

  1. Preheat your oven to 400 degrees F. Line a sheet pan with foil and spray it with cooking spray.
  2. Clean the portobello mushrooms, removing the stems and gently scraping out the gills with a spoon. Brush the tops with olive oil and place them stem side up on the sheet pan.
  3. Bake the mushrooms for about 10–15 minutes until they soften. Drain any excess liquid before continuing.
  4. In a non-stick skillet, spray with cooking spray, heat over medium, and add the egg substitute, stirring until light and fluffy. Incorporate the chopped spinach, cooking until just wilted.
  5. Add black pepper, crushed red pepper flakes, and cottage cheese, and remove from heat.
  6. Spoon about 1/4 to 1/2 cup of the egg mixture into each mushroom cap. Sprinkle a teaspoon of Parmesan cheese on top.
  7. Place the mushrooms under the broiler until the cheese is golden and bubbly, then remove from the oven. Garnish with fresh basil before serving.
