Pesto, egg, Parmesan
Portobello mushrooms are versatile and can be stuffed with various ingredients. One option is to stuff them with pesto, egg, and Parmesan. This combination makes for a savoury, low-carb breakfast option and can be served as an impressive brunch dish for guests.
To prepare the mushrooms, use a damp cloth to remove any dirt. Cut off the stems and use a spoon to carefully remove the gills without breaking the sides. If the mushrooms are too small and there isn't enough room for an egg, you can scrape out some of the mushroom flesh to make space. It is recommended to choose portobello mushrooms with higher sides so that the egg doesn't spill out.
For the filling, spread about one tablespoon of pesto into each mushroom. Gently crack an egg into each mushroom and season with salt and pepper. Sprinkle grated Parmesan cheese on top.
Bake the stuffed mushrooms in a preheated oven until the egg whites are set and the yolks are cooked to your desired doneness. This should take around 12 to 15 minutes. You can garnish with parsley and serve with toast and warm beefsteak tomatoes on the side.
If you're making these stuffed mushrooms for a brunch gathering, you can prepare them ahead of time and freeze them before baking. They can be stored in an airtight container for up to three months.
