Ingredients
- 18 large white button or cremini mushrooms
- 1 tablespoon butter
- 2 cloves garlic, minced
- 1 cup chopped fresh spinach
- 4 ounces cream cheese, softened

- Step 2: Melt the butter in a skillet over medium heat. Cook the chopped mushroom stems and garlic for 2 to 3 minutes until softened. Add the spinach and cook until wilted, then remove from the heat.
- Step 3: In a mixing bowl, combine the cream cheese, half of the mozzarella, cheddar, Parmesan, sun-dried tomatoes, Italian seasoning, garlic powder, salt, and pepper. Stir in the cooked mushroom mixture until well combined.
- Step 4: Fill each mushroom cap generously with the cheese mixture and place them on a baking sheet. Sprinkle the remaining mozzarella over the tops.
- Step 5: Bake for about 15 minutes, or until the mushrooms are tender and the cheese is melted and lightly golden.
- Step 6: Let the mushrooms cool for a few minutes before garnishing with fresh parsley. Serve warm.
Tips & Variations
- For extra flavor, add a pinch of red pepper flakes to the cheese mixture for a mild kick.
- You can substitute fresh spinach with kale or Swiss chard if preferred.
- Using cremini mushrooms gives a deeper flavor, but white button mushrooms work just as well.
- Try adding cooked sausage or bacon bits for a heartier filling.
Storage
Store any leftover stuffed mushrooms in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) for about 10 minutes to keep the mushrooms tender and cheese melted.

- Salt, to taste

Garnish
- 1 tablespoon chopped fresh parsley
Instructions
- Preheat and prepare mushrooms: Preheat your oven to 375°F (190°C). Remove the stems from the mushrooms and finely chop them. Wipe the mushroom caps clean gently with a damp paper towel to ensure they’re free of dirt.
- Sauté stems and spinach: In a skillet over medium heat, melt the butter. Add the chopped mushroom stems and minced garlic, cooking for 2 to 3 minutes until softened. Then add the chopped spinach and cook until wilted. Remove from heat once done.

Stir in the cooked mushroom stem and spinach mixture until everything is thoroughly combined.
- Stuff mushrooms: Generously fill each mushroom cap with the prepared cheese and vegetable mixture. Arrange the stuffed mushrooms on a baking sheet and sprinkle the remaining mozzarella cheese over the tops to create a melty, golden crust.
- Bake: Place the baking sheet in the preheated oven and bake for 15 to 20 minutes or until the mushrooms are tender, the cheese is fully melted, and the tops develop a light golden color.
- Garnish and serve: Allow the mushrooms to cool slightly before garnishing with freshly chopped parsley. Serve warm as an appetizer or snack.
