How to Make Low Carb Spaghetti Squash Casserole
This Low Carb Spaghetti Squash Casserole is surprisingly simple to put together, proving that healthy eating doesn’t have to be complicated.

Step-by-Step Instructions
- Prepare the Spaghetti Squash: Preheat your oven to 400°F (200°C). Carefully cut the spaghetti squash in half lengthwise. Scoop out the seeds and stringy bits using a spoon. Drizzle the cut sides with olive oil and sprinkle with salt and pepper. Place the squash halves cut-side down on a baking sheet lined with parchment paper.
- Roast the Spaghetti Squash: Roast for 40-50 minutes, or until the flesh is tender when pierced with a fork. The cooking time will vary depending on the size of your squash.
- Cook the Meat Sauce: While the squash is roasting, heat a large skillet or Dutch oven over medium-high heat. Add the ground turkey or chicken and cook, breaking it up with a spoon, until browned. Drain off any excess grease.
- Sauté Aromatics: Add the chopped onion to the skillet with the browned meat and cook until softened, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.
- Simmer the Sauce: Pour in the low-sugar marinara sauce. Stir in the Italian seasoning and dried basil. Bring the mixture to a simmer, then reduce the heat to low and let it cook for at least 10-15 minutes to allow the flavors to meld.
- Shred the Squash: Once the spaghetti squash is tender, remove it from the oven and let it cool slightly so it’s easier to handle. Use a fork to scrape out the spaghetti-like strands from the flesh, leaving the shell intact to hold the filling.
- Assemble the Casserole: In the same skillet with the meat sauce, add the shredded spaghetti squash and stir to combine thoroughly. The warmth of the sauce will gently cook the squash strands.
- Add Cheese: Sprinkle half of the shredded mozzarella cheese and all of the grated Parmesan cheese over the meat and squash mixture in the skillet. Stir gently until the cheeses start to melt and create a creamy sauce.
- Bake the Casserole: Spoon the mixture back into the hollowed-out spaghetti squash shells, or if the shells have broken, transfer the mixture to a greased 9×13 inch baking dish. Top evenly with the remaining mozzarella cheese.
- Final Bake: Place the filled squash halves (or the baking dish) back into the preheated oven. Bake for another 15-20 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
- Serve: Let the casserole rest for a few minutes before serving. Garnish with fresh chopped parsley if desired.
