Ingredients

4 large portobello mushrooms
2 ripe avocados
4 large eggs
1 cup cherry tomatoes, halved
2 cloves garlic, minced
1 tablespoon olive oil
Salt and pepper to taste
Fresh parsley or cilantro for garnish (optional)
Crushed red pepper flakes (optional for a spicy kick)

Instructions

Step 1: Clean the portobello mushrooms by gently wiping the caps with a damp paper towel. Remove the stems and scrape out the gills with a spoon to reduce bitterness and create space for the filling. Set aside.
Step 2: Halve and pit the avocados. Scoop the flesh into a bowl and mash it to a chunky consistency. Stir in minced garlic, salt, pepper, and crushed red pepper flakes if using. Mix well.
Step 3: Toss the halved cherry tomatoes with a drizzle of olive oil, salt, and pepper in a small bowl. Set aside.
Step 4: Preheat the oven to 375°F (190°C). Arrange the mushrooms on a baking sheet lined with parchment paper or lightly greased. Trim edges if necessary to help them sit flat.
Step 5: Spoon the avocado mixture evenly into each mushroom cap, leaving a space in the center for the egg.
Step 6: Crack an egg into a small bowl, then carefully pour it into the center of each stuffed mushroom. Repeat for all mushrooms.
Step 7: Bake for 15–20 minutes until eggs reach your desired doneness. For runny yolks, bake about 15 minutes; for firm yolks, bake closer to 20 minutes.
Step 8: Five minutes before the mushrooms finish baking, scatter the cherry tomatoes around them on the baking sheet to roast slightly.
Step 9: Remove from the oven and let cool for a few minutes. Garnish with chopped parsley or cilantro if desired, then serve warm.

Tips & Variations

Use ripe but firm avocados to ensure the filling holds its shape well.
For extra flavor, sprinkle some grated cheese over the avocado before adding the egg.
If you prefer a vegetarian version without eggs, simply skip the eggs and bake the stuffed mushrooms with avocado and tomatoes.
Adding a squeeze of fresh lemon juice to the mashed avocado prevents browning and adds brightness.
Swap cherry tomatoes for sun-dried tomatoes for a more intense flavor.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven or microwave to avoid overcooking the eggs. The mushrooms are best enjoyed fresh but can be reheated carefully.

FAQs

Can I prepare this recipe ahead of time?

You can prepare the avocado mixture and clean the mushrooms a few hours ahead, but it’s best to assemble and bake just before serving to keep the eggs fresh and the mushrooms from becoming soggy.

What if I don’t have portobello mushrooms?

Large white button mushrooms can be used as a substitute, but they are smaller, so you may need more mushrooms and adjust cooking time accordingly.
