Step‑by‑Step Instructions for Avocado and Egg Stuffed Portobello Mushrooms
Step 1: Prep Mushrooms
Begin by preheating your oven to 375°F (190°C). Gently wipe the Portobello mushrooms with a damp cloth to clean them, avoiding excess moisture. Carefully remove the stems and scrape out the gills using a small spoon or knife, ensuring you don’t break the caps. Set the cleaned mushrooms aside to prepare for the delicious filling.
Step 2: Make Filling
In a bowl, mash ripe avocados with minced garlic, salt, and pepper until creamy and well-blended. This avocado mixture will become the heart of your Avocado and Egg Stuffed Portobello Mushrooms, adding rich flavors and healthy fats. Adjust the seasoning as needed, then set the filling aside while you prepare the tomatoes.
Step 3: Prepare Tomatoes
Take the cherry tomatoes and slice them in half. Toss the halved tomatoes in a small bowl with a drizzle of olive oil, sprinkle of salt, and pepper to enhance their natural sweetness. These tomatoes will not only add flavor but also vibrant color to your dish, so set them aside for later.
Step 4: Stuff Mushrooms
Carefully spoon the avocado mixture into each Portobello cap, filling them generously while leaving enough space for the eggs. Gently crack an egg into each stuffed mushroom, ensuring the yolk remains intact. This step is key for a beautifully presented Avocado and Egg Stuffed Portobello Mushrooms, so take your time.
Step 5: Bake
Place the prepared mushrooms on a baking sheet lined with parchment paper for easy cleanup. Bake in the preheated oven for 15 to 20 minutes, depending on your preferred egg consistency. Keep an eye on the mushrooms; the egg whites should be set, while the yolks can remain slightly runny for a beautiful, gooey finish.
Step 6: Add Tomatoes
About 5 minutes before the mushrooms are done, scatter the prepared cherry tomatoes around them on the baking sheet. This allows the tomatoes to roast slightly, enhancing their flavors and ensuring they are perfectly tender when serving. The aroma in your kitchen will be absolutely delightful!
Step 7: Garnish and Serve
Once out of the oven, let the mushrooms cool for a minute. Garnish your Avocado and Egg Stuffed Portobello Mushrooms with fresh parsley or cilantro for a vibrant touch. Serve them on a plate alone or with a simple side salad. This dish is not just a feast for the taste buds but also for the eyes!

Storage Tips for Avocado and Egg Stuffed Portobello Mushrooms
Fridge: Place any leftover Avocado and Egg Stuffed Portobello Mushrooms in an airtight container in the refrigerator for up to 3 days.
Freezer: For longer storage, freeze the stuffed mushrooms before baking. Wrap individually in plastic wrap and place in a freezer-safe bag for up to 2 months.
Reheating: Reheat baked mushrooms in the oven at 350°F (175°C) for 10–15 minutes, or until warmed through. Avoid the microwave, which can make the mushrooms soggy.
Make-Ahead: Prepare the avocado filling and store it in the fridge for up to 1 day. Assemble the mushrooms just before baking for optimal freshness.

Avocado and Egg Stuffed Portobello Mushrooms Recipe FAQs
How do I select ripe avocados for this recipe?
Absolutely! Look for avocados that yield softly to gentle pressure. The skin should be dark and slightly bumpy, but avoid any with dark spots all over, as this indicates overripeness. If you’re in a hurry, you can opt for guacamole as a quick substitute.
What is the best way to store leftovers?
You can store any leftover Avocado and Egg Stuffed Portobello Mushrooms in an airtight container in the refrigerator for up to 3 days. Just remember to cool them completely before sealing to maintain texture. When you’re ready to enjoy them again, reheat in the oven for the best results!
Can I freeze the stuffed mushrooms?
Certainly! To freeze, assemble the stuffed mushrooms but skip the baking. Wrap each mushroom individually in plastic wrap, then place them in a freezer-safe bag. They can be stored for up to 2 months. When you’re ready to bake, simply remove them from the freezer and bake directly from frozen, adding a few extra minutes to the cooking time.
What should I do if the egg yolks break while stuffing?
Very! If your egg yolks break, don’t fret! To save your dish, just gently pour the contents of the broken egg into a small bowl. You can stir it lightly and pour it back into the mushroom cap for a lovely scrambled effect. It’ll still taste delicious, and the creamy avocado will balance nicely with the cooked egg.
Are these mushrooms suitable for pets?
No, it’s best to avoid sharing these stuffed mushrooms with your furry friends. While both avocados and mushrooms are safe in moderation for some animals, the combination may cause stomach upset or digestive issues for pets. As a precaution, stick to pet-friendly options when treating your beloved companions.
Can I make these stuffed mushrooms dairy-free?
