How to Make Sausage and Peppers Spaghetti Squash Casserole
-
Preheat the Oven: Start by preheating your oven to 400°F (200°C). This ensures your casserole cooks beautifully and evenly.
-
Prepare the Squash: Cut the spaghetti squash in half lengthwise. Scoop out the seeds and strings, drizzle with olive oil, and season with salt and pepper. Place the halves cut side down on a baking sheet and roast for 30-35 minutes, or until tender.
-
Cook the Sausage: While the squash bakes, heat a large skillet over medium heat. Add the Italian sausage, breaking it up with a spoon, and cook for about 5-7 minutes until fully browned.

Sauté the Vegetables: Once the sausage is nearly cooked through, add the diced onion and bell pepper to the skillet. Sauté for another 3-5 minutes, until the vegetables soften and become fragrant.

Add Flavorings: Stir in the minced garlic, diced tomatoes (with their juices), Italian seasoning, and red pepper flakes (if using). Cook for an additional 3-4 minutes, allowing the flavors to meld. Season with salt and pepper to taste.
-
Combine Squash and Mixture: When the spaghetti squash is done roasting, carefully flip the halves over and use a fork to scrape out the flesh into strands. Combine these squash strands with the sausage mixture in the skillet, stirring until well mixed.
-
Transfer and Top: Transfer the mixture into a greased casserole dish. Generously top with shredded mozzarella and Parmesan cheese for that cheesy, golden finish.
-
Bake the Casserole: Place the casserole in the oven and bake for 20-25 minutes, or until the cheese is bubbly and golden brown.

Sausage and Peppers Spaghetti Squash Casserole Recipe FAQs
How do I choose the best spaghetti squash?
Absolutely! When selecting spaghetti squash, look for a firm, heavy squash with a smooth, yellow exterior. Avoid any that have dark spots or blemishes, as this may indicate over-ripeness or spoilage. A medium-sized squash typically weighs around 3-4 pounds, giving you plenty of delicious spaghetti strands to work with.

Very! To store leftovers, allow the Sausage and Peppers Spaghetti Squash Casserole to cool completely before placing it in an airtight container. It can be kept in the refrigerator for up to 3 days. Just remember to seal it tightly so it retains its flavor and moisture!
Can I freeze the casserole for later use?
Absolutely! To freeze your casserole, allow it to cool completely, then transfer it to a freezer-safe container. Make sure to label it with the date, and it can last in the freezer for up to 3 months. When you’re ready to enjoy it again, thaw it overnight in the refrigerator and reheat it in the oven at 350°F (175°C) until it’s heated through, which should take about 25-30 minutes.
What are some common troubleshooting tips for this recipe?
If you find your spaghetti squash strands are not forming properly, it could be due to overcooking. Aim to roast until just tender—if you notice it’s mushy, consider reducing the roasting time next time. Additionally, if the casserole seems too dry, try adding a splash of vegetable broth or tomato sauce during the mixing stage before baking; this can add moisture and flavor.
Are there any dietary considerations for this dish?
Very! If you’re considering dietary restrictions, this casserole can easily be made gluten-free by ensuring your sausage has no fillers. For a lighter option, swap the Italian sausage for turkey or chicken sausage. It’s also great for low-carb diets; just be cautious with additional toppings like bread or high-carb accompaniments. As for pets, always keep this dish out of their reach, especially since garlic and certain seasonings can be harmful to them.
How can I make this dish vegetarian?
For a vegetarian twist, substitute the Italian sausage with plant-based sausage or sautéed mushrooms for that savory depth. You could also use lentils for added texture and protein. Just be sure to season adequately to keep those hearty flavors intact!
