  • 4 large portobello mushrooms
  • Olive oil spray
  • 1/2 teaspoon Diamond Crystal kosher salt divided
  • 1/2 teaspoon black pepper, divided
  • 1/2 teaspoon garlic powder
  • 4 medium eggs
  • 2 tablespoons grated Parmesan cheese
  • 4 tablespoons chopped parsley for garnish


  • Preheat broiler, setting the temperature to high. Set an oven rack in the middle of the oven. Line a rimmed broiler-safe baking sheet with foil.
  • Wipe the mushrooms clean with a damp paper towel. Gently twist off or the stem of each mushroom. Holding each mushroom in one hand, use a spoon to gently scrape out the gills.
  • Spray the mushroom caps with olive oil cooking spray on both sides. Sprinkle with 1/4 teaspoon kosher salt, 1/8 teaspoon pepper, and 1/4 teaspoon garlic powder. Broil 5 minutes on each side, or until just tender.
  • Remove the mushrooms from the oven. Drain any liquids. Switch oven from broil to bake, setting the temperature to 400 degrees F.
  • Break an egg into each mushroom. Sprinkle with the cheese. Bake 15 minutes, until the egg whites are cooked.
  • Sprinkle the eggs with the remaining 1/4 teaspoon salt and 1/8 teaspoon pepper. Garnish with parsley and serve.
