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 small spoon or knife, creating a spacious cavity for the filling. This preparation ensures the mushrooms are clean and ready to showcase the delicious avocado and egg filling.
Step 2: Prepare the Avocado Filling
In a mixing bowl, mash the ripe avocado with minced garlic, salt, pepper, and optional crushed red pepper flakes until the mixture is creamy but still chunky. This vibrant filling provides a rich, savory taste, perfectly complementing the earthy portobello mushrooms. Set the filling aside while you cut the tomatoes, allowing the flavors to meld.
Step 3: Season the Cherry Tomatoes
Slice the cherry tomatoes in half and place them in a bowl. Drizzle with olive oil and season with salt and pepper to enhance their natural sweetness. This step adds a burst of flavor that will elevate your dish and provide a delightful contrast to the creamy avocado. Set the seasoned tomatoes aside as you preheat the oven.
Step 4: Preheat the Oven
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper or lightly grease it with olive oil. This ensures the portobello mushrooms bake evenly and do not stick, resulting in perfectly roasted vegetables. While the oven heats, prepare for the final assembly of your Avocado and Egg Stuffed Portobello Mushrooms.
Step 5: Assemble the Mushrooms
Evenly distribute the avocado mixture into the cleaned mushroom caps, leaving a gentle well in the center for the egg. Crack an egg into each mushroom cap, ensuring the yolk remains intact. This step creates a delightful centerpiece for each stuffed mushroom, with the creamy avocado providing a delicious backdrop to the egg.
Step 6: Bake Your Creation
Place the assembled portobello mushrooms onto the prepared baking sheet and bake in the preheated oven for 15–20 minutes. Keep an eye on them to achieve your desired egg doneness; the whites should be set, and the yolks slightly soft. In the last 5 minutes of baking, add the seasoned cherry tomatoes around the mushrooms for roasting.
Step 7: Garnish and Serve
Once baked to perfection, remove the mushrooms from the oven and allow them to cool slightly. Garnish the Avocado and Egg Stuffed Portobello Mushrooms with fresh herbs like parsley or cilantro for a burst of color and flavor. Serve warm, either as an elegant breakfast or light dinner, delighting your taste buds with every bite.
