Prepare the Spaghetti Squash

• Preheat the oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise, scoop out the seeds, and place the halves cut-side down on a baking sheet. Roast for 35-40 minutes or until tender.
• Heat a skillet over medium heat. Add a bit of oil, then sauté the chopped onion until softened. Add the minced garlic and cook for an additional minute.
• Mix in the cooked meat, Marinara sauce, seasonings, half the Mozzarella cheese and Parmesan cheese.
• When the squash is cool enough to handle, scrape out the strands with a fork and reduce oven temperature to 375°F (190°C).
• Mix the spaghetti strands to the mixture,
• Spread the mixture evenly in a greased 9x13-inch (23x33 cm) baking dish and top with the remaining cheese. Add any other toppings of your choice.
• Bake for 20-25 minutes, or until the cheese is melted and bubbly. For a crispy top, broil for an additional 2-3 minutes.
• Let the casserole rest for a few minutes before serving. Top with shredded fresh basil and enjoy the pizza goodness!
