Ingredients (Makes 16–20 Stuffed Mushrooms)
-
16–20 large button or cremini mushrooms
-
1 cup fresh spinach, finely chopped
-
1/2 cup cottage cheese (for extra protein)
-
1/2 cup shredded mozzarella cheese

2 cloves garlic, minced

1 tablespoon olive oil

Why This Is a High-Protein Snack
Unlike traditional stuffed mushrooms that rely mostly on cream cheese, this recipe uses cottage cheese combined with mozzarella and Parmesan. Cottage cheese significantly increases the protein content while keeping the filling creamy and lighter.
Mushrooms themselves are low in calories and rich in nutrients, making this a balanced snack option.
Step-by-Step Instructions
Step 1: Prepare the Mushrooms
Preheat your oven to 375°F (190°C).
Gently wipe mushrooms clean with a damp cloth. Remove stems and finely chop them (you can use them in the filling).
Place mushroom caps on a lined baking sheet.
Step 2: Sauté the Filling Base
Heat olive oil in a small skillet over medium heat. Add garlic and chopped mushroom stems. Cook for 2–3 minutes until softened.
Add chopped spinach and cook until wilted (about 1–2 minutes). Remove from heat and let cool slightly.
Step 3: Mix the Cheese Filling
In a bowl, combine cottage cheese, mozzarella, Parmesan, sautéed spinach mixture, salt, pepper, and optional red pepper flakes. Stir until well combined.
Step 4: Stuff the Mushrooms
Spoon the filling into each mushroom cap, slightly mounding the mixture on top.
Step 5: Bake
Bake for 18–20 minutes, or until mushrooms are tender and the tops are golden and bubbly.
Let cool for a few minutes before serving.
