Ingredients
Mushrooms and Eggs
- 6 large portobello mushrooms
- 6 large eggs
Vegetables and Herbs
- 1 cup fresh spinach, chopped
- 1/2 medium onion, diced
- 2 cloves garlic, minced
- A few sprigs of fresh basil, rosemary, or parsley, chopped (or dried herbs if preferred)
Cheese and Seasoning
- 1 cup shredded mozzarella cheese
- Salt and pepper to taste
- Olive oil (for brushing and sautéing)
Instructions
- Preheat the oven: Set your oven to 425°F (220°C) to ensure it reaches the ideal temperature for baking the mushrooms and eggs.
- Prepare the mushroom caps: Gently wipe the portobello mushrooms with a damp paper towel to clean off any dirt. Remove the stems and use a spoon to carefully scrape out the gills inside the caps, creating a nice cavity to hold fillings.
- Brush and bake mushrooms: Lightly coat both sides of the mushroom caps with olive oil. Place them top side down on a baking sheet lined with foil, then bake for 5 minutes to begin softening.
- Sauté the spinach mixture: While the mushrooms bake, heat some olive oil in a pan over medium heat. Add diced onion, minced garlic, and chopped spinach. Cook until the spinach wilts and the onions become translucent, then remove from heat.
- Remove mushroom liquid: Take the mushrooms out of the oven, carefully pouring out any liquid that has accumulated inside the caps. You can reserve this flavorful liquid for use in soups if desired.
- Assemble mushrooms: Return the mushroom caps to the baking sheet, this time right side up. Layer each with the sautéed spinach mixture, shredded mozzarella cheese, and chopped fresh herbs, leaving a small well in the center for the egg.
- Add the eggs: Gently crack one egg into the center of each mushroom cap on top of the fillings. Sprinkle with salt and pepper to taste.
- Bake until cooked: Place the assembled mushrooms back in the oven and bake for 8-10 minutes. Bake until the egg whites are set and the yolks reach your desired level of doneness.
Notes
- Check the eggs frequently towards the end of baking to ensure yolks do not overcook; baking time may vary depending on oven and egg size.
- Feel free to substitute mozzarella with other melty cheese types like cheddar or feta for different flavor profiles.
- Use dried herbs if fresh are unavailable, but reduce quantity slightly as dried herbs are more concentrated in flavor.
- The mushroom liquid can be saved and added to soups or sauces to enhance flavor.
- This recipe is naturally gluten-free and low-carb, making it suitable for gluten-free and low-calorie diets.
