Ingredients (Serves 4 | About 16 stuffed mushrooms)

For the Mushrooms:

• 16 medium white or cremini mushrooms, stems removed and cleaned

• 1 tbsp olive oil

• Salt and pepper, to taste

For the Filling:

• 1 tbsp butter

• 2 cloves garlic, minced

• 2 cups fresh spinach, chopped

• 1/2 tsp sea salt

• 1/4 tsp black pepper

• 1/4 tsp nutmeg (optional)

• 4 oz cream cheese, softened

• 1/3 cup shredded mozzarella cheese

• 2 tbsp grated Parmesan cheese

Instructions

Prep Time: 10 minutes
Cook Time: 20 minutes
Total Time: 30 minutes

1. Preheat the Oven:
   Set your oven to 375°F (190°C). Prepare a baking sheet by lining it with parchment paper or greasing it lightly.

2. Prep the Mushrooms:
   Gently clean mushrooms with a damp cloth. Remove and finely chop the stems (you'll use these in the filling). Toss the mushroom caps with olive oil, salt, and pepper. Set aside.

3. Sauté the Filling:
   In a skillet over medium heat, melt butter. Add garlic and chopped mushroom stems; cook for 2 minutes. Stir in spinach, salt, pepper, and optional nutmeg. Cook until spinach wilts (about 2–3 minutes).

4. Make It Creamy:
   Lower the heat and mix in the cream cheese until it’s melted and fully incorporated. Remove from heat and mix in mozzarella and Parmesan. Let the mixture cool slightly.

5. Stuff the Mushrooms:
   Fill each mushroom cap with the creamy spinach mixture. Arrange them evenly on the prepared baking sheet.

6. Bake to Perfection:
   Bake for 18–20 minutes or until mushrooms are tender and tops are lightly golden.

7. Cool & Serve:
   Let them cool slightly before serving warm.
