How to Make Cheesy Spaghetti Squash Gratin

Making Cheesy Spaghetti Squash Gratin is a breeze. Here’s a step-by-step guide to help you along the way:

1. 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 with olive oil, salt, and pepper. Place cut-side down on a baking sheet and roast for 30-35 minutes, until tender.
2. Sauté the Vegetables: While the squash is roasting, heat the olive oil in a large skillet over medium heat. Add the onion and garlic, and cook until softened, about 5 minutes.
3. Add the Tomatoes: Stir in the diced tomatoes, oregano, basil, salt, and black pepper. Simmer for 10 minutes.
4. Assemble the Gratin: Once the squash is done, use a fork to scrape out the strands into a baking dish. Pour the tomato mixture over the squash and top with the shredded mozzarella and grated Parmesan cheese.
5. Bake: Bake in the preheated oven for 20-25 minutes, until the cheese is melted and bubbly.
6. Serve: Let the gratin cool for a few minutes, then serve with your favorite toppings. Enjoy!
