Ingredients
For the Spaghetti Squash:
- 1 medium spaghetti squash
- 1 tablespoon olive oil
- Salt and pepper, to taste
For the Casserole Filling:
- 1 cup ricotta cheese
- 1 large egg white
- ½ cup freshly grated Parmesan cheese
- 2 cups fresh spinach, chopped
- 1 teaspoon Italian seasoning
- ½ teaspoon garlic powder
- Salt and pepper, to taste
For the Topping:
- 1 cup shredded mozzarella cheese
- Fresh parsley, chopped (optional, for garnish)
Instructions
1. Prepare the Spaghetti Squash:
- Preheat your oven to 400°F (200°C).
- Slice the spaghetti squash in half lengthwise and remove the seeds. Drizzle the cut sides with olive oil and season with salt and pepper.
- Place the halves cut-side down on a baking sheet lined with parchment paper. Roast for 40-45 minutes, or until the flesh is tender and can be shredded into strands with a fork.
- Once cooled enough to handle, use a fork to scrape the flesh of the squash into spaghetti-like strands. Set aside.
2. Prepare the Casserole Filling:
- In a large bowl, combine the ricotta cheese, egg white, Parmesan cheese, chopped spinach, Italian seasoning, garlic powder, salt, and pepper. Mix until well combined.
3. Assemble the Casserole:
- In a greased 9×13-inch baking dish, spread the shredded spaghetti squash evenly at the bottom.
- Spread the ricotta-spinach mixture over the squash layer.
- Sprinkle the shredded mozzarella cheese evenly on top.
4. Bake:
- Preheat your oven to 350°F (175°C).
- Bake the assembled casserole for 25-30 minutes, or until the cheese on top is melted and bubbly.
5. Serve:
- Remove from the oven and let it rest for about 5 minutes before serving.
- Garnish with chopped fresh parsley if desired. Slice and enjoy!
