Step 1

Preheat oven to 350 degrees F and line a rimmed baking sheet with a Silpat or parchment paper.

Step 2

Place whole spaghetti squash in the microwave for 5 minutes. This helps slightly soften the squash so it's easier to cut open.

Step 3

Remove from the microwave and carefully cut in half, length-wise. Scoop out the seeds and pulp from the middle.

Step 4

Drizzle each half with 1 tablespoon olive oil and season liberally with kosher salt and pepper.

Step 5

Roast for 1 hour or until the flesh of the squash will shred when scraped with a fork.

Step 6

While the squash is cooking make the sauce that will stuff the squash.

Step 7

In a large skillet set over medium-high heat add sausage and break up while you stir. If the pan gets too dry simply drizzle in a little olive oil so the sausage does not stick to the bottom or burn.

Step 8

Once the sausage is lightly browned add in peppers and onions. Continue cooking until the sausage is fully browned and the vegetables are soft.

Step 9

Add in garlic and Italian spice. Cook until the garlic is fragrant, about 30 seconds.

Step 10

Pour in tomato sauce and simmer while the squash cooks. You are looking for a little of the water in the sauce to simmer away leaving a nice thick sauce.

Step 11

Once the squash is fully cooked remove it from the oven and carefully scrape and fluff the flesh until fully shredded. Lightly press down into the squash half and fill each squash half with half the sausage/sauce mixture.

Step 12

Top with cheese and place under the broiler for about 15 minutes to melt and brown the cheese.

Step 13

Scoop out of the squash and serve. A 4-pound squash should give you enough for 4 servings, 2 servings per squash.
