Spinach and Cheese Stuffed Portobello Mushroom (Print Version)

# Ingredients:

→ For the Mushrooms

01 - 4 large portobello mushroom caps, stems and gills removed
02 - 2 tablespoons olive oil, divided

→ For the Filling

03 - 1 teaspoon minced garlic
04 - 1/2 cup finely chopped onion
05 - 2 cups fresh spinach, roughly chopped
06 - 1/2 cup ricotta cheese
07 - 1/4 cup grated Parmesan cheese, plus extra for garnish
08 - 1/4 teaspoon salt
09 - 1/4 teaspoon black pepper
10 - 1/4 teaspoon nutmeg (optional)
11 - 1/2 cup shredded mozzarella cheese

# Instructions:

01 - Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper. Brush both sides of the mushroom caps with olive oil and place them gill-side up on the prepared baking sheet.
02 - Bake the mushroom caps for about 10 minutes until they start to release water. This helps prevent a soggy final dish.
03 - While mushrooms are pre-baking, heat remaining olive oil in a large skillet over medium heat. Add garlic and onion, cooking until softened, about 3-4 minutes. Add spinach and cook until wilted, about 2-3 minutes more. Remove from heat and let cool slightly.
04 - In a bowl, combine the spinach mixture with ricotta cheese, Parmesan cheese, salt, pepper, and nutmeg if using. Mix well until thoroughly combined.
05 - Spoon the cheese and spinach mixture evenly into the pre-baked mushroom caps. Top each with a portion of the shredded mozzarella cheese.
06 - Return stuffed mushrooms to the oven and bake for 15-20 minutes more, until cheese is bubbly and golden brown.
07 - Garnish with additional grated Parmesan cheese before serving. Enjoy while warm!

# Notes:

01 - Removing the mushroom gills creates more room for filling and prevents the dish from turning dark in color
