Step‑by‑Step Instructions for Avocado and Egg Stuffed Portobello Mushrooms
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C) to ensure it reaches the perfect temperature for baking. This step is essential to achieve those tender, flavorful Portobello mushrooms. While the oven heats up, gather your baking sheet and line it with parchment paper for easier cleanup and to prevent sticking.
Step 2: Prepare the Portobello Mushrooms
Carefully clean the portobello mushrooms by wiping them down with a damp paper towel; this removes any dirt without soaking them. Remove the stems and gently scrape out the gills with a spoon to make room for your filling. This step not only enhances the presentation but also allows the flavors of your Avocado and Egg Stuffed Portobello Mushrooms to shine through.
Step 3: Make the Avocado Mixture
In a medium bowl, mash ripe avocados with minced garlic, salt, and pepper until you reach a chunky consistency. Feel free to add optional red pepper flakes for a kick! The creamy texture of the avocado will complement the eggs beautifully. Set this flavorful mixture aside while you prepare the other ingredients.
Step 4: Prep the Cherry Tomatoes
Halve the cherry tomatoes and combine them in a small bowl with olive oil, salt, and pepper. Toss them gently to ensure all the tomatoes are evenly coated. Letting them marinate for a moment will enhance their sweetness, making the dish even more delicious when paired with the stuffed mushrooms.
Step 5: Assemble the Stuffed Mushrooms
Place the cleaned portobello caps on your prepared baking sheet, gill-side up. Generously fill each mushroom with the avocado mixture, creating a small well in the center for the egg. Gently crack an egg into the center of each filled mushroom, allowing the yolk to nestle in the avocado. This combination is what makes your Avocado and Egg Stuffed Portobello Mushrooms so indulgent!
Step 6: Bake the Mushrooms
Transfer the baking sheet to the preheated oven and bake for 15 to 20 minutes. Keep an eye on the mushrooms, checking at the 15-minute mark for your desired egg yolk doneness; the egg whites should be set while the yolk can remain runny or be cooked through, depending on your preference.
Step 7: Roast the Cherry Tomatoes
With about 5 minutes remaining in the baking time, add the marinated cherry tomatoes to the baking sheet around the mushrooms. This will allow them to roast until slightly caramelized, enhancing their flavor and providing a perfect complement to your Avocado and Egg Stuffed Portobello Mushrooms.
Step 8: Garnish and Serve
Once cooked to perfection, remove the baking sheet from the oven and let cool for a couple of minutes. Garnish your stuffed mushrooms with fresh parsley or cilantro for an added burst of freshness and color. Serve warm and enjoy the delightful flavors and textures of this nutritious dish!

Avocado and Egg Stuffed Portobello Mushrooms Recipe FAQs
How do I choose ripe avocados?
Absolutely! When selecting avocados, gently squeeze the fruit; it should yield slightly under pressure, indicating ripeness. If you find hard avocados, you can place them in a paper bag with a banana to speed up the ripening process.
How can I store leftover Avocado and Egg Stuffed Portobello Mushrooms?
For sure! Store any leftovers in an airtight container in the fridge for up to 2 days. This keeps your mushrooms fresh and packed with flavor. When you’re ready to enjoy them again, simply reheat in the oven at 350°F (175°C) for about 10-15 minutes.
Can I freeze Avocado and Egg Stuffed Portobello Mushrooms?
Absolutely! To freeze, I recommend assembling the stuffed mushrooms without the egg. Wrap them tightly in plastic wrap and then in foil to prevent freezer burn. They can be stored for up to 3 months. When you’re ready to bake, just pop them straight into the oven from the freezer, and cook until warmed through.
What should I do if the egg yolk breaks while cracking into the mushroom?
It happens to the best of us! If the yolk breaks, don’t worry; you can still proceed with baking. Just gently stir the contents to integrate it, and it will still taste delicious. If you want to avoid this, cracking the eggs into a separate bowl first can help you ensure yolk integrity.
Are there any dietary considerations for this recipe?
Very much so! This recipe is gluten-free and low-carb, making it suitable for various dietary preferences, including vegetarian and keto-friendly diets. If you’re cooking for someone with an egg allergy, consider substituting the egg with a flax egg or silken tofu for a vegan-friendly version.
What if I don’t like the taste of portobello mushrooms?
No problem! Feel free to use medium-sized bell peppers or large zucchini boats instead. They act as perfect substitutes, offering a mild flavor while still providing a sturdy base for your avocado and egg filling!
