- 1 tablespoon olive oil
- Salt and pepper to taste
For the Italian Sausage Filling:
- 1 pound Italian sausage (sweet or hot, your choice!), casings removed
- 1 medium onion, chopped
- 2 cloves garlic, minced

- 1 teaspoon dried oregano
- 1/2 teaspoon dried basil

Let’s Get Cooking: Step-by-Step Instructions

Step 1: Prep the Spaghetti Squash
- Preheat your oven to 400°F (200°C).
- Carefully cut the spaghetti squash in half lengthwise. Trust me, this can be tricky! A sharp knife and a steady hand are your best friends. If the squash is being stubborn, you can microwave it for 2-3 minutes to soften it slightly.
- Scoop out the seeds and stringy bits from the center of each half.
- Brush the cut sides of the squash with olive oil, then season generously with salt and pepper.
- Place the squash halves cut-side down on a baking sheet.
Step 2: Roast the Squash
- Roast the squash in the preheated oven for 40-50 minutes, or until the flesh is easily pierced with a fork. The roasting time will depend on the size of your squash.
Step 3: Make the Italian Sausage Filling
- While the squash is roasting, prepare the Italian sausage filling. In a large skillet, brown the Italian sausage over medium heat, breaking it up with a spoon as it cooks. Drain off any excess grease.
- Add the chopped onion and cook until softened, about 5 minutes.
- Stir in the minced garlic and red bell pepper and cook for another 2-3 minutes, until fragrant.
- Pour in the crushed tomatoes and tomato sauce. Stir in the dried oregano, dried basil, and red pepper flakes (if using). Season with salt and pepper to taste.
- Bring the sauce to a simmer and cook for 15-20 minutes, stirring occasionally, to allow the flavors to meld.
Step 4: Assemble the Stuffed Squash Boats
- Once the spaghetti squash is cooked, remove it from the oven and let it cool slightly.
- Use a fork to shred the squash flesh into spaghetti-like strands. Leave the strands inside the squash “boats.”
- Spoon the Italian sausage filling evenly into the squash boats, dividing it between the two halves.
- Sprinkle the top of each boat with shredded mozzarella cheese and grated Parmesan cheese.
Step 5: Bake to Perfection
- Return the stuffed squash boats to the oven and bake for another 10-15 minutes, or until the cheese is melted and bubbly.
Step 6: Serve and Enjoy!
- Remove the Italian Sausage Stuffed Spaghetti Squash Boats from the oven and let them cool slightly before serving.
- Garnish with fresh parsley and serve hot. Get ready for a flavor explosion!
Tips and Tricks for Stuffed Squash Success
Okay, friend, let’s talk strategy. A perfectly executed Mushroom Ricotta Zucchini Boats can be a game changer, and so can these Italian Sausage Stuffed Spaghetti Squash Boats! Here are some secrets to ensure your squash boats are the best they can be:
- Spice it up (or down): Don’t be afraid to adjust the amount of red pepper flakes to your liking. If you prefer a milder flavor, you can omit them altogether.
- Get creative with the cheese: Mozzarella and Parmesan are classic choices, but you can also use other cheeses like provolone, fontina, or even a sprinkle of ricotta for extra creaminess.

- Make it ahead: You can roast the spaghetti squash and prepare the Italian sausage filling ahead of time. Store them separately in the refrigerator and assemble the squash boats just before baking.
