Roasted Spaghetti Squash Lasagna Boats

Step 1
Preheat the oven to 400 degrees F (200 degrees C).

Step 2
Cut squash in half lengthwise with a large kitchen knife. Scoop out seeds and membrane. Season lightly with salt and pepper. Place in a baking dish, cut-side down.

Step 3
Bake in the preheated oven until soft, about 45 minutes. Remove from the oven and let cool for about 10 minutes. Keep the oven on.

Step 4
Meanwhile, begin preparing sauce. Combine ricotta cheese, Parmesan cheese, and parsley in a medium bowl. Mix well.

Step 5
Heat oil in a large, deep skillet over medium heat. Saute onion and garlic in the hot oil until onion is soft, 3 to 4 minutes. Add sausage and cook and stir until browned, 5 to 7 minutes, breaking up meat into small pieces as it cooks. Add tomatoes, salt, and pepper. Simmer over low heat for 25 minutes; stir in basil and simmer for 5 minutes more.

Step 6
Remove flesh from the cooled squash by scraping with a fork, creating spaghetti strands. Reserve the shells. Drain the squash strands in a paper towel-lined colander to soak up excess liquid.

Step 7
Toss squash strands with the tomato sauce mixture. Spoon into the 6 squash shells. Top with 1 to 2 tablespoons of the ricotta cheese mixture and 2 tablespoons mozzarella cheese. Place in the baking dish.

Step 8
Roast in the preheated oven until heated through and cheese is melted, about 30 minutes.
