Step‑by‑Step Instructions for Avocado and Egg Stuffed Portobello Mushrooms
Step 1: Prepare Mushrooms
Gently clean the portobello mushrooms using a damp paper towel to remove any dirt, being careful not to soak them. Remove the stems and gills using a spoon, creating space for the filling. Arrange the cleaned mushroom caps on a baking sheet lined with parchment paper, ensuring they are sturdy and ready to be stuffed.
Step 2: Make Avocado Filling
In a mixing bowl, mash ripe avocados with a fork until smooth, then stir in minced garlic, salt, pepper, and optional crushed red pepper flakes. Blend these ingredients until evenly combined, creating a creamy filling that packs flavor. This avocado mixture will serve as the heart of your Avocado and Egg Stuffed Portobello Mushrooms, providing richness and healthy fats.
Step 3: Season Tomatoes
Halve the cherry tomatoes and place them in a small mixing bowl. Drizzle with a splash of olive oil, and season with salt and pepper to enhance their natural sweetness. Toss everything together until the tomatoes are evenly coated, then set them aside to marinate while you prepare the mushrooms for baking.
Step 4: Preheat Oven
Preheat your oven to 375°F (190°C) to ensure the environment is ready for baking. This step is crucial for achieving perfectly cooked stuffed mushrooms, allowing the flavors to meld and the eggs to set just right. As the oven heats, you can proceed to the next step of stuffing the mushrooms.
Step 5: Stuff Mushrooms
Carefully fill each portobello mushroom cap with the avocado mixture, pressing it lightly to hold its shape. Once filled, make a small indentation in the center of each mushroom, and crack an egg gently into this space. This will create the signature look and flavor of the Avocado and Egg Stuffed Portobello Mushrooms, so take care to keep the yolk intact.
Step 6: Bake
Place the stuffed mushrooms in the preheated oven and bake for 15-20 minutes. After the first 10 minutes, carefully add the seasoned cherry tomatoes around the mushrooms to roast alongside them. Keep an eye on the mushrooms; you want the egg whites to be set while the yolks remain slightly runny for that perfect creamy texture.
Step 7: Serve
Once baked, remove the stuffed mushrooms from the oven and let them cool for a minute. Garnish with fresh parsley or cilantro for a pop of color and extra flavor. Plate them up, allowing the deliciousness of the Avocado and Egg Stuffed Portobello Mushrooms to shine through. Serve them warm, and don’t forget to enjoy the delightful aroma that fills your kitchen!

Avocado and Egg Stuffed Portobello Mushrooms Recipe FAQs
What should I look for when selecting portobello mushrooms?
Look for portobello mushrooms that are firm and evenly colored without dark spots or blemishes. The caps should feel sturdy and have a pleasant, earthy smell that indicates freshness. Avoid any mushrooms that appear slimy or have a strong odor, as these can indicate spoilage.
How should I store leftover stuffed mushrooms?
Place any leftovers in an airtight container in the refrigerator where they can stay fresh for up to 2 days. To maintain the creamy texture of the avocado filling, enjoy them as soon as possible. If you want to keep them longer, consider freezing before baking.
Can I freeze Avocado and Egg Stuffed Portobello Mushrooms?
Absolutely! To freeze, prepare the stuffed mushrooms but do not bake them. Wrap each one tightly with plastic wrap, then in aluminum foil to prevent freezer burn. They can be frozen for up to 3 months. When you’re ready to enjoy them, bake straight from frozen at 375°F (190°C) for 25-30 minutes, or until heated through.
