¼ teaspoon salt – This basic seasoning enhances the natural flavors of the mushrooms.

¼ teaspoon freshly ground pepper, divided – Freshly ground pepper adds depth and a hint of heat, enhancing the entire dish.

1 cup part-skim ricotta cheese – A creamy base that binds the filling together with its luscious texture.

1 cup finely chopped fresh spinach – Adds vibrant color and essential nutrients, making the filling both delicious and healthy.

½ cup finely shredded Parmesan cheese, divided – This flavorful cheese provides a savory contrast and a crispy top layer when baked.

2 tablespoons finely chopped kalamata olives – These add a briny punch, taking the flavor profile to the next level.

How to Make Spinach & Cheese Stuffed Portobello

Follow these simple steps to prepare this delicious Spinach & Cheese Stuffed Portobello:

Step 1: Preheat the Oven
Preheat your oven to 450°F (232°C) and prepare your baking sheet by coating it with cooking spray for easy cleanup later.

Step 2: Roast the Mushroom Caps
Place the mushroom caps, gill-side up, on the prepared baking sheet. Sprinkle salt and 1/8 teaspoon of pepper over them. Roast in the oven for about 20-25 minutes until tender.

Step 3: Prepare the Filling
While the mushrooms roast, combine the ricotta cheese, chopped spinach, 1/4 cup of Parmesan, kalamata olives, Italian seasoning, and the remaining 1/8 teaspoon of pepper in a medium bowl. Mash everything together until well blended, creating a heavenly filling.

Step 4: Heat the Marinara Sauce
Pour the marinara sauce into a small bowl, cover it, and microwave on high until it’s hot—this should take about 30 seconds to 1.5 minutes.

Step 5: Fill the Mushroom Caps
Once the mushrooms are out of the oven, carefully pour out any liquid that may have accumulated in them. Return the caps to the pan, gill-side up, and spread 1 tablespoon of marinara in each cap. Now, generously mound about 1/3 cup of the ricotta filling into each mushroom and sprinkle with the remaining 1/4 cup of Parmesan cheese.

Step 6: Bake the Stuffed Mushrooms
Pop those beautiful stuffed portobellos back in the oven and bake for an additional 10 minutes until the filling is hot and bubbly. Serve with the remaining marinara sauce drizzled on top for an extra flavor punch.
