Step‑by‑Step Instructions for Avocado and Egg Stuffed Portobello Mushrooms
Step 1: Clean the Mushrooms
Begin by gently wiping the Portobello mushrooms with a damp paper towel to remove any dirt. Carefully remove the stems and gills using a spoon to create a cavity for stuffing. This preparation step is essential to ensure your mushrooms are clean and ready for the delicious avocado and egg filling.
Step 2: Prepare Avocado Filling
In a mixing bowl, mash the ripe avocados until smooth, and then add minced garlic, salt, pepper, and optional red pepper flakes for a touch of spice. Mix everything until well combined, creating a creamy avocado mixture that will provide a flavorful base. This filling is both nutritious and delicious—a perfect match for your Portobello mushrooms.
Step 3: Preheat Oven
Preheat your oven to 375°F (190°C). This is an important step to ensure that your Avocado and Egg Stuffed Portobello Mushrooms cook evenly, allowing the eggs to set properly and the mushrooms to become tender. Meanwhile, prepare a baking sheet lined with parchment paper or lightly greased for easy cleanup.
Step 4: Fill Mushrooms
Take each cleaned Portobello mushroom and generously spoon the avocado mixture into the cavity, leaving space for an egg in the center. Make sure the filling is packed in well and slightly mounded to create a delightful contrast between the creamy avocado and the baked egg. This step sets the stage for the star of the dish!
Step 5: Add Eggs
Carefully crack an egg into each stuffed mushroom cap, placing the yolk right in the center of the avocado mixture. Ensure the yolk remains intact for a beautiful presentation. This step is crucial, as the egg adds richness and protein to the dish, making it a satisfying meal that’s perfect any time of day.
Step 6: Bake
Place the prepared mushrooms on the baking sheet and transfer them to the preheated oven. Bake for 15-20 minutes, watching closely for the desired doneness: the egg whites should be set, while the yolks can remain runny if you prefer. This baking time allows the flavors to meld beautifully, resulting in a mouthwatering dish.
Step 7: Add Tomatoes
About 5 minutes before the mushrooms are done baking, scatter halved cherry tomatoes around them on the baking sheet. These cherry tomatoes will roast to perfection, adding a burst of sweetness and color to your Avocado and Egg Stuffed Portobello Mushrooms. This extra touch enhances both the visual appeal and flavor of the dish.
Step 8: Garnish & Serve
Once baked, remove the mushrooms from the oven and let them cool slightly. For an extra pop of flavor and freshness, garnish with chopped parsley or cilantro. Serve these beautiful Avocado and Egg Stuffed Portobello Mushrooms warm, either as a stunning main dish or a delightful side, making them perfect for any meal.

Make Ahead Options
These Avocado and Egg Stuffed Portobello Mushrooms are perfect for busy home cooks looking to meal prep! You can prepare the avocado filling up to 24 hours in advance and store it in an airtight container to prevent browning (a squeeze of lemon juice can also help). The mushrooms can be cleaned and stuffed with the filling, but it’s best to wait until just before baking to crack the eggs in. When you’re ready to enjoy this delightful dish, simply pop the stuffed mushrooms in the oven for 15-20 minutes, and you’ll have fresh, restaurant-quality results with minimal effort!

Avocado and Egg Stuffed Portobello Mushrooms Recipe FAQs
How do I choose the right Portobello mushrooms?
Absolutely! When selecting Portobello mushrooms, look for caps that are firm, smooth, and evenly colored. Avoid any with dark or wet spots, as these may indicate spoilage. A fresh Portobello will have a pleasant, earthy aroma and spring back slightly when pressed.
How should I store leftover stuffed Portobello mushrooms?
Very good question! Store any leftover Avocado and Egg Stuffed Portobello Mushrooms in an airtight container in the refrigerator for up to 3 days. When reheating, I recommend using the oven at 350°F (175°C) to ensure they warm through evenly without losing their delightful texture.
Can I freeze the stuffed mushrooms?
Yes, you can! To freeze, prepare the stuffed mushrooms but don’t bake them yet. Place the unbaked mushrooms in a single layer on a baking sheet, freeze until solid, and then transfer them to a freezer-safe container. They will keep well for up to 2 months. When ready to enjoy, bake them directly from frozen, adding approximately 5-10 extra minutes to the cooking time.
What if the eggs overflow when baking?
That can happen! If you’re concerned about overflow, crack each egg into a small bowl first, and then carefully pour it into the mushroom cap. This way, you can catch any shell pieces before they go into your dish. Also, using slightly smaller eggs or adjusting the amount of avocado filling can help leave more room for the egg.
Are these mushrooms suitable for pets or those with specific allergies?
It’s best to be cautious! While Portobello mushrooms, avocados, and eggs are generally safe for humans, they can be harmful to pets, especially avocados. Additionally, if anyone has allergies to these ingredients, such as egg allergies or avocado sensitivities, it’s important to personalize the recipe to their dietary needs. Always consult with a healthcare professional for specific dietary concerns.
