Ingredients

  • 1 cup whole milk

  • 1 1/4 cups frozen spinach, thawed and drained

  • 1 tbsp fresh sage, chopped

  • 1 tbsp fresh thyme

  • 2 garlic cloves, minced

  • 8 oz mozzarella cheese, shredded and divided

  • Sea salt and black pepper, to taste

  • 2 small spaghetti squash, halved lengthwise and seeds removed

  • 1/4 cup grated Parmigiano Reggiano

How to Make Alfredo Stuffed Spaghetti Squash

  1. Preheat the oven. Preheat to 425°F (220°C).

  2. Prepare the filling. In a bowl, combine the milk, spinach, sage, thyme, garlic, and two-thirds of the shredded mozzarella. Season with salt and black pepper and mix well.

  3. Fill the squash. Season the spaghetti squash halves with salt and pepper and arrange them in a baking dish, cut sides facing up. Divide the spinach and cheese mixture among the squash halves. Top with the remaining mozzarella and grated Parmesan.

  4. Bake until tender. Cover the baking dish with foil and bake for 30 minutes. Remove the foil and bake for another 20 minutes, or until the squash is tender and the cheese is golden.

  5. Scrape and serve. Use a fork to scrape the spaghetti squash flesh into strands, mixing it with the creamy cheese filling. Serve warm and enjoy!

Tips and Variations

Add protein: Make this a more protein-rich meal by adding cooked chicken, turkey, or shrimp to the filling.

Switch up the cheese: Try a blend of mozzarella and provolone, or add extra Parmesan for a richer, more savory flavor.

Add extra toppings: Fresh basil, red pepper flakes, or pine nuts make delicious finishing touches.

Make it a complete meal: Pair your stuffed spaghetti squash with a green salad or roasted non-starchy vegetables.
