Ingredients

• 2 medium-sized spaghetti squash
• 2 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 1 pound sweet Italian sausage
• 1 large red bell pepper, diced
• 1 large yellow bell pepper, diced
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 can (28 ounces) crushed tomatoes
• 1 teaspoon dried Italian seasoning
• 0.25 teaspoons red pepper flakes (optional)
• 2 cups shredded mozzarella cheese
• 0.5 cup grated Parmesan cheese
• 2 tablespoons fresh basil, chopped

Directions

Step 1

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil for easy cleanup.

Step 2

Cut the spaghetti squashes in half lengthwise and scoop out the seeds with a spoon.

Step 3

Drizzle the cut sides of the squash halves with 1 tablespoon of olive oil and sprinkle with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Place them cut-side down on the prepared baking sheet.

Step 4

Roast the squash in the oven for 40-50 minutes, or until the flesh is tender and easily shredded with a fork. Let cool slightly before scraping out the strands with a fork and setting them aside.

Step 5

While the squash roasts, heat the remaining 1 tablespoon of olive oil in a large skillet over medium-high heat.

Step 6

Add the sweet Italian sausage, breaking it up into smaller pieces with a wooden spoon, and cook for 5-7 minutes until browned and cooked through. Remove the sausage and set aside.

Step 7

In the same skillet, add the diced red and yellow bell peppers, onion, and minced garlic. Sauté for 5-7 minutes, or until the vegetables are softened and fragrant.

Step 8

Stir in the crushed tomatoes, Italian seasoning, red pepper flakes (if using), and the remaining 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. Let the sauce simmer for 10 minutes to develop flavors.

Step 9

Add the cooked sausage back into the skillet and stir to combine with the sauce. Remove from heat.

Step 10

In a 9x13 inch casserole dish, spread half of the cooked spaghetti squash strands evenly on the bottom. Top with half of the sausage and pepper mixture, followed by 1 cup of shredded mozzarella cheese.

Step 11

Repeat the layering process with the remaining spaghetti squash, sausage mixture, and mozzarella cheese.

Step 12

Sprinkle the grated Parmesan cheese evenly over the top.

Step 13

Bake the casserole in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.

Step 14

Remove from the oven and let cool for 5 minutes. Garnish with fresh chopped basil before serving.
