Ingredients List for Spinach and Cheese Stuffed Portobello Mushroom

2 large Portobello mushrooms
1 tablespoon olive oil
1/2 teaspoon garlic powder
1/4 teaspoon salt

1 tablespoon butter
2 cups fresh spinach
1/2 cup ricotta cheese
1/2 cup shredded mozzarella cheese
1/4 cup grated Parmesan cheese
1/4 teaspoon crushed red pepper flakes

How To Make Spinach and Cheese Stuffed Portobello Mushroom Step-by-Step

1. Preheat the Oven

Preheat your oven to 375°F (190°C).

2. Clean the Mushrooms

Clean the Portobello mushrooms by gently wiping the caps with a damp cloth or paper towel to remove any dirt.

3. Prepare the Mushroom Caps

Remove the stems from the mushrooms and carefully scrape out the gills using a spoon, creating space for the filling.

4. Arrange on Baking Sheet

Place the mushroom caps, stem side up, on a baking sheet lined with parchment paper.

5. Drizzle with Olive Oil

Drizzle the olive oil evenly over the mushroom caps, ensuring they are lightly coated.

6. Season the Mushrooms

Sprinkle the garlic powder, salt, and black pepper over the mushrooms.

7. Bake the Mushrooms

Place the mushrooms in the oven and bake for 10-12 minutes, or until the mushrooms start to soften.

8. Sauté the Spinach

While the mushrooms are baking, melt the butter in a large skillet over medium heat.
Add the fresh spinach to the skillet and sauté, stirring occasionally, until the spinach wilts, about 3-4 minutes.

9. Cool the Spinach

Remove the skillet from heat and let the spinach cool slightly.

10. Remove Excess Moisture

Once the spinach has cooled, transfer it to a clean kitchen towel or paper towels to absorb any excess moisture.

11. Mix the Cheese

In a medium mixing bowl, combine the ricotta cheese, shredded mozzarella cheese, grated Parmesan cheese, and crushed red pepper flakes.

12. Add Spinach to Cheese

Once the spinach is dry, chop it finely and add it to the cheese mixture.

13. Combine Well

Stir everything together until the spinach is evenly distributed throughout the cheese mixture.

14. Fill the Mushroom Caps

After 10-12 minutes of baking, remove the mushroom caps from the oven. Spoon the spinach and cheese mixture into the center of each mushroom cap, packing it in gently.

15. Final Bake

Return the stuffed mushrooms to the oven and bake for an additional 10–12 minutes, or until the cheese is melted and bubbly.

16. Cool and Serve

Once done, remove the stuffed mushrooms from the oven and let them cool for a couple of minutes before serving.
