Recipe: Keto Cheesy Egg-Stuffed Portobello Mushrooms

Servings: 4
Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes

Ingredients

• 4 large Portobello mushrooms, stems removed and gills scraped out

• 4 large eggs

• ½ cup shredded mozzarella cheese

• ¼ cup grated Parmesan cheese

• 2 tablespoons olive oil

• ½ teaspoon garlic powder

• ¼ teaspoon salt

• ¼ teaspoon black pepper

• 1 tablespoon fresh parsley, chopped (for garnish)

Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.

2. Prepare the Mushrooms

Clean each mushroom cap gently using a damp paper towel.
Remove stems and scrape out the dark gills with a spoon to make space for the filling.
Brush both sides of each mushroom with olive oil, then sprinkle with garlic powder, salt, and pepper.

3. Pre-Bake the Mushrooms

Place mushrooms gill-side up on your lined baking sheet.
Bake for 8 minutes to help release moisture.
Once done, carefully pat dry the inside with paper towels to prevent sogginess.

4. Fill with Eggs & Cheese

Crack one egg into the center of each mushroom cap.
Top evenly with shredded mozzarella and grated Parmesan.

5. Bake Until Set

Return the tray to the oven and bake for 12–15 minutes, or until egg whites are set.
For a runnier yolk, check at the 12-minute mark; for a firmer yolk, bake slightly longer.

6. Garnish and Serve

Sprinkle with fresh chopped parsley just before serving.
Enjoy hot for a protein-packed, keto-friendly meal!

Tips & Variations

• Make it spicy: Add a dash of crushed red pepper flakes or hot sauce before serving.

• Add bacon: Crumbled cooked bacon can be sprinkled on top with the cheese for extra flavor.

• Dairy-free? Use a dairy-free shredded cheese substitute and skip the Parmesan.
