Step‑by‑Step Instructions for Spaghetti Squash Casserole Low Carb Comfort Food
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C) and grab a 9x13 inch casserole dish. Lightly coat the dish with a tablespoon of extra-virgin olive oil to ensure your Spaghetti Squash Casserole doesn’t stick. This will help achieve a perfectly crisp and golden finish on the sides of your casserole.
Step 2: Sauté the Meats
In a large skillet set over medium heat, warm a splash of olive oil. Add one pound each of ground beef and Italian sausage to the skillet, cooking until they're halfway browned, approximately 5-7 minutes. Next, toss in the diced onion, sautéing for about 3 minutes until softened, creating a flavorful base for your meat mixture.
Step 3: Add Flavors
Stir in the minced garlic, Italian seasoning, salt, pepper, and optional red pepper flakes, letting these aromatic ingredients mingle for an additional minute. This step will elevate the flavor profile of your Spaghetti Squash Casserole, filling your kitchen with a delightful aroma that will entice everyone around you.
Step 4: Simmer with Sauce
Pour in two cups of marinara sauce, stirring well to combine. Allow this mixture to gently simmer for about 10 minutes, giving the flavors time to deepen. You'll know it's ready when the sauce is bubbling softly, infusing the kitchen with rich, comforting aromas that signal deliciousness ahead.
Step 5: Prepare the Cheese Mixture
In a separate mixing bowl, combine 15 ounces of ricotta cheese, 8 ounces of softened cream cheese, and ¼ cup of chopped parsley. Season this cheesy mix with salt and pepper, then fold in ½ cup of grated Parmesan for an added layer of richness. This creamy mixture is what will make your Spaghetti Squash Casserole delightfully indulgent.
Step 6: Layer It Up
In your prepared casserole dish, layer half of the pre-cooked spaghetti squash as your base. Follow with half of the meat sauce, then spoon half of the cheese mixture over that. Repeat the layering process until all components are used, ensuring a balance of flavor and texture in every bite of your casserole.
Step 7: Add Cheese Topping
To finish off your Spaghetti Squash Casserole, sprinkle 2 cups of grated mozzarella cheese evenly over the top. This will create a beautifully melty layer as it bakes. Prepare to pop it into the oven for 20-25 minutes, or until the cheese is bubbly and golden brown, making the dish visually appealing and utterly irresistible.
Step 8: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for about 10 minutes. This resting period allows the flavors to meld and makes serving easier. Finally, garnish with fresh parsley or basil before diving into this comforting low-carb masterpiece—your family will thank you!
Make Ahead Options
These Spaghetti Squash Casserole Low Carb Comfort Food delights are perfect for busy weeknights! You can prepare the meat sauce and cheese mixture up to 3 days in advance, storing them separately in airtight containers in the refrigerator. Additionally, you can layer the squash, sauce, and cheese in the casserole dish without baking it. Just cover it well and refrigerate for up to 24 hours. To maintain quality, ensure each component is fully cooled before refrigerating. When you're ready to enjoy, simply bake it straight from the fridge for an extra 5-10 minutes, until it's bubbly and perfectly golden. This way, you’ll savor restaurant-quality comfort food with minimal effort any night of the week!

Spaghetti Squash Casserole Recipe FAQs
How do I pick the best spaghetti squash?
Absolutely! When selecting a spaghetti squash, look for one that feels heavy for its size and has a hard, yellow skin. Avoid squashes with dark spots or soft areas, as these may indicate ripeness issues. A fresh spaghetti squash can last up to 1 month when stored in a cool, dry place.
What’s the best way to store leftovers?
Very! To store your leftovers, place them in an airtight container in the fridge, where they will stay fresh for up to 3 days. If you want to keep the casserole longer, consider portioning it into individual serving sizes, which makes reheating a breeze!
Can I freeze the spaghetti squash casserole? How?
Yes, you can! To freeze, allow the casserole to cool completely, then transfer it to a freezer-safe container. Make sure to label it with the date!

This ensures that it remains warm and retains its wonderful flavors.
What if my casserole is too watery?
No problem! If your casserole turns out watery, it might be due to excess moisture in the spaghetti squash or marinara sauce.
