Ingredients You’ll Need
For the Casserole
- 1 medium spaghetti squash
- 1 cup marinara sauce (homemade or store-bought)
- 1 cup ricotta cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 cup cooked ground turkey or beef (optional, for added protein)
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
For the Topping
- 1/2 cup breadcrumbs (or almond flour for a low-carb option)
- 2 tablespoons olive oil
- Fresh basil or parsley for garnish
Note: For the best results, choose a fresh spaghetti squash that feels heavy for its size and has a smooth skin. You can easily substitute the ground turkey with lentils for a vegetarian option.
How to make Simple Spaghetti Squash Casserole
Step 1
Preheat your oven to 400°F (200°C). This ensures the casserole will cook evenly and gives it a nice golden top.
Step 2
Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the insides with a bit of olive oil, then sprinkle with salt and pepper. Place the squash halves cut-side down on a baking sheet lined with parchment paper.
Step 3
Roast the squash in the preheated oven for about 40-45 minutes, or until the flesh is tender and can easily be scraped into strands with a fork.
Step 4
While the squash is baking, prepare the casserole filling. In a mixing bowl, combine the ricotta cheese, half of the mozzarella, ground turkey (if using), Italian seasoning, salt, and pepper.
Step 5
Once the squash is cooked, remove it from the oven and let it cool for a few minutes. Using a fork, carefully scrape the flesh into strands and add it to the ricotta mixture. Gently combine all ingredients until evenly mixed.
Step 6
In a greased baking dish, spread about half of the marinara sauce on the bottom. Layer the spaghetti squash mixture on top, followed by the remaining sauce. Finish with the rest of the mozzarella and sprinkle the grated Parmesan cheese on top.
Step 7
For the final touch, combine breadcrumbs with olive oil and sprinkle over the top layer. This will add a beautiful crispness to your casserole.
Step 8
Bake the casserole for an additional 20-25 minutes, until the cheese is melted and bubbly and the top is golden brown.
Tips & Recipe Variations
- Lower-Carb Option: Substitute breadcrumbs with almond flour to keep this casserole low-carb.
- Vegetarian Version: Omit meat and load up on veggies like spinach or mushrooms for added nutrients.
- Storage: Leftovers can be stored in the refrigerator for up to 4 days. Reheat in the oven for best results.
- Make Ahead: Assemble the casserole the night before and store it in the fridge, then bake it the following day.
How to Serve
This delicious spaghetti squash casserole is best enjoyed warm, straight from the oven. Serve it alongside a light green salad dressed in vinaigrette to balance the richness. A glass of sparkling water with lemon or a light white wine pairs beautifully with the dish. For a picturesque presentation, garnish with freshly chopped basil or parsley before serving.
