Breakfast Stuffed Mushrooms Ingredients
For the Mushrooms
• Portabella Mushrooms – These serve as the perfect vessel for a savory filling; you can use large button mushrooms as a substitution.
• Extra Virgin Olive Oil – Adds moisture and flavor; feel free to replace with avocado oil or melted butter.
For the Filling

Step‑by‑Step Instructions for Breakfast Stuffed Mushrooms
Step 1: Prepare the Mushrooms
Begin by preheating your oven to 375°F (190°C). While the oven heats, gently clean the portabella mushrooms using a damp paper towel to remove any dirt. Next, use a spoon to carefully remove the gills from the underside of each mushroom, creating space for the savory filling. Place the mushrooms stem-side up on a lined baking sheet for easy handling.
Step 2: Mix the Filling
In a medium bowl, combine the breadcrumbs, shredded Manchego cheese, garlic powder, sliced scallions, melted butter, milk, salt, and pepper. Stir the mixture until fully blended, ensuring the breadcrumbs are evenly coated and moistened. This colorful, savory filling will enhance your Breakfast Stuffed Mushrooms and bring out wonderful flavors when baked.
Step 3: Season the Mushrooms
Drizzle extra virgin olive oil over the tops of the mushrooms, ensuring a light coating, and season generously with salt and fresh ground pepper. Carefully flip the mushrooms over so they sit top-side down on the baking sheet. This surface will provide a flavorful crispness as they bake, while the filling will remain cozy inside.
Step 4: Fill the Mushrooms
Using a spoon, generously scoop the filling into each mushroom cap, pressing it slightly to pack it in. Make a small well in the center of the filling for the eggs, ensuring enough space for each egg to sit without spilling. These Breakfast Stuffed Mushrooms are ready to take on the next layer of deliciousness!
Step 5: Bake the Stuffed Mushrooms
Place the filled mushrooms in the preheated oven and bake for approximately 10 minutes, allowing the cheese to melt and the filling to set. You’ll know they’re ready when the tops are golden and fragrant, filling your kitchen with a mouthwatering aroma of savory goodness.
Step 6: Add the Eggs
Carefully remove the mushrooms from the oven. Crack an egg into each well you created earlier, allowing the yolk to sit gently on top of the filling. Lightly season the eggs with salt and pepper, and sprinkle with any remaining scallions for added flavor.
Step 7: Final Bake
Return the baking sheet to the oven and bake for an additional 10-15 minutes. Keep an eye on the mushrooms; you want the egg whites to be set while the yolks remain slightly jiggly, creating a lovely creamy texture. This step ensures your Breakfast Stuffed Mushrooms are both visually appealing and deliciously satisfying.
Step 8: Serve and Enjoy
Once the eggs are cooked to your liking, remove the Breakfast Stuffed Mushrooms from the oven and let them cool briefly. Serve them warm alongside a light salad or fresh fruit for a balanced meal. Each bite delivers delightful flavors and a hearty texture that’s sure to impress your family and friends.

Breakfast Stuffed Portabella Mushrooms with Egg Recipe FAQs
How do I choose the right mushrooms for this recipe?
Absolutely! When selecting portabella mushrooms, look for caps that are firm, smooth, and free from dark spots or blemishes. They should be a nice, rich brown color and feel heavy for their size, indicating they’re fresh and packed with moisture. If portabella isn’t available, large button mushrooms make an excellent substitute!
What’s the best way to store leftover stuffed mushrooms?
Very! Store any leftover Breakfast Stuffed Mushrooms in an airtight container in the fridge for up to 3 days. To reheat, simply pop them in a preheated oven at 350°F (175°C) for about 15 minutes or until warmed through, ensuring the eggs remain deliciously creamy.
Can I freeze these stuffed mushrooms?
Absolutely! To freeze, prepare the stuffed mushrooms without the eggs and wrap each one tightly in plastic wrap. Place them in a freezer-safe bag, and they’ll last for up to 3 months. When you’re ready to enjoy, bake them fresh with the eggs added, and follow the original baking instructions for the best results.
What should I do if my mushrooms look soggy after baking?
No worries! If your mushrooms turn out soggy, it’s often due to excess moisture. To avoid this in the future, ensure you pat the mushrooms dry before cooking and do not over-season with liquids. If they still seem wet, bake them for an additional few minutes to help evaporate excess moisture.
Are there any allergy concerns with this recipe?
Absolutely! This recipe contains common allergens, including dairy (in the cheese and milk) and eggs. If someone is lactose intolerant, consider using non-dairy milk and a dairy-free cheese. For a meat-free option, replace the eggs with a mix of sautéed vegetables or pre-cooked breakfast sausage.
Can I prep these mushrooms ahead of time?
Yes, indeed! You can prep the stuffed mushrooms (without the eggs) up to 3 days in advance. Store them in the fridge covered tightly with plastic wrap. When you’re ready to bake them, simply add the eggs to the wells and cook immediately. This makes them a perfect solution for busy mornings!
