Ingredients
- 1 large spaghetti squash
- 2 tablespoons olive oil
- 1 onion, chopped
- 2 cloves garlic, minced
- 1 bell pepper, chopped
- 1 zucchini, chopped
- 1 cup mushrooms, sliced
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon red pepper flakes (optional)
- 2 cups marinara sauce
- 1 cup ricotta cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- Salt and black pepper to taste
- Fresh basil leaves for garnish (optional)
Instructions
- Prepare the Spaghetti Squash: Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the inside with 1 tablespoon of olive oil and season with salt and pepper. Place the squash halves cut-side down on a baking sheet and roast for 35-40 minutes, or until the flesh is tender and easily shredded with a fork. Let it cool slightly, then use a fork to scrape the strands into a bowl. Reduce the oven temperature to 375°F (190°C).
- Cook the Vegetables: In a large skillet, heat the remaining tablespoon of olive oil over medium heat. Add the onion and garlic, and sauté until fragrant, about 2 minutes. Add the bell pepper, zucchini, and mushrooms, and cook until the vegetables are softened, about 5-7 minutes. Stir in the oregano, basil, and red pepper flakes, if using. Season with salt and black pepper to taste.
- Assemble the Casserole: In a large mixing bowl, combine the cooked spaghetti squash, sautéed vegetables, and marinara sauce. Stir in the ricotta cheese until well mixed.
- Layer the Casserole: Spread half of the spaghetti squash mixture into a greased 9×13-inch baking dish. Sprinkle half of the mozzarella and Parmesan cheese over the top. Repeat with the remaining spaghetti squash mixture and cheeses.
- Bake the Casserole: Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown.
- Serve: Let the casserole cool for a few minutes before serving. Garnish with fresh basil leaves if desired, and enjoy!
Spaghetti Squash Casserole is a delicious and comforting dish that’s packed with flavor and nutrition, making it a perfect choice for a wholesome meal. Enjoy the blend of vegetables, rich sauce, and melted cheese in every bite!
