Step‑by‑Step Instructions for Avocado and Egg Stuffed Portobello Mushrooms
Step 1: Prepare Mushrooms
Begin by preheating your oven to 375°F (190°C). Gently clean the portobello mushrooms with a damp paper towel to remove any dirt and debris. Carefully remove the stems and use a spoon to scrape out the gills to create ample space for the filling. Set your cleaned mushrooms cap-side up on a baking sheet, ready for stuffing.
Step 2: Make Filling
In a mixing bowl, mash the ripe avocados until creamy, then incorporate the minced garlic, salt, pepper, and optional crushed red pepper flakes for a touch of heat. Stir the mixture until fully combined and smooth. This creamy filling will give the Avocado and Egg Stuffed Portobello Mushrooms a delightful flavor and texture that perfectly compliments the mushrooms.
Step 3: Fill Mushrooms
Using a spoon, generously fill each portobello mushroom cap with the avocado mixture, creating a little well in the center to hold the egg. Make sure the filling is even and level, allowing the creamy texture to mingle beautifully with the mushrooms. This will enhance the taste profile as it cooks, promising a hearty delight with each bite.
Step 4: Add Eggs
Carefully crack an egg into the well of each filled mushroom. Try to keep the yolk intact for a beautiful presentation once baked. If you prefer, you can crack the eggs into a small bowl first, ensuring no shell fragments disrupt your dish. This step will create the rich and satisfying center that defines your Avocado and Egg Stuffed Portobello Mushrooms.
Step 5: Roast
Place the filled mushrooms in the preheated oven and roast them for 15–20 minutes. Keep an eye on them—bake until the egg is set to your desired consistency: 15 minutes for runny yolks and closer to 20 minutes for more firm, fully cooked eggs. The mushrooms should be tender, and the dish will emit a delicious aroma.
Step 6: Add Tomatoes
Five minutes before the roasting time is completed, scatter the halved cherry tomatoes around the mushrooms. This not only adds vibrant color but enhances the overall flavor by roasting alongside the mushrooms. Your kitchen will soon be filled with a delightful scent as everything melds together.
Step 7: Serve
Once roasted, remove the Avocado and Egg Stuffed Portobello Mushrooms from the oven and let them cool for a minute. Garnish generously with your choice of fresh herbs, like parsley or cilantro, to add a pop of color and freshness. Serve warm, and enjoy this nutritious meal that’s a feast for both the eyes and the palate!

Avocado and Egg Stuffed Portobello Mushrooms Recipe FAQs
How do I select ripe avocados for this recipe?
Absolutely! Look for avocados that yield slightly under gentle pressure. The skin should be dark green and free of large dark spots or blemishes. If it’s too hard, give it a few days to ripen at room temperature; you can speed this up by placing it in a brown paper bag with an apple or banana!
What’s the best way to store leftover stuffed mushrooms?
Very! After you’ve enjoyed your dish, store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place them in a preheated oven at 350°F (175°C) for about 10-15 minutes, ensuring they’re heated through without compromising the texture.
Can I freeze the stuffed mushrooms, and how should I do it?
Definitely! While the best flavor is when enjoyed fresh, you can freeze uncooked stuffed mushrooms for up to 1 month. To freeze, wrap them tightly in plastic wrap and then place them in a freezer-safe bag. When you’re ready to bake, thaw them overnight in the fridge before popping them in the oven.
What can I do if the eggs crack during roasting?
Don’t worry! If you notice a crack, it’s usually just cosmetic. To prevent this, you can crack the eggs into a bowl first, then gently pour them into the hollowed mushroom caps. If an egg breaks, just remove any shell fragments and be extra gentle when placing the filled mushrooms in the oven!
Are there any dietary considerations I should be aware of?
Absolutely! This dish is naturally gluten-free and can be made vegan by substituting eggs with a plant-based alternative. For those with allergies, make sure to check for any sensitivities to ingredients like avocado or eggs. Always create a safe eating space by accommodating any dietary needs.
