How to Make Spaghetti Squash Casserole with Ground Turkey Recipe
Step 1: Roast the Spaghetti Squash
Start by preheating your oven to 375°F (190°C). Slice the spaghetti squash in half lengthwise and scoop out the seeds for a neat, squash “boat.” Place the halves cut-side down on a greased baking sheet – this helps caramelize the flesh as it roasts. Roast it for about 30 to 40 minutes until the squash is tender and you can easily shred it into strands with a fork. This step is crucial because the squash texture is what makes this casserole so special.
Step 2: Sauté Aromatics and Cook Ground Turkey
While the squash is roasting, heat a tablespoon of olive oil in a large skillet over medium heat. Toss in the chopped onion and minced garlic and sauté for about 2 to 3 minutes until fragrant. The aroma at this stage is so inviting, it’s an excellent sign that the flavors are building. Next, add the ground turkey, breaking it apart with a spoon as it cooks. Let it brown for 5 to 7 minutes until fully cooked and no pink remains. This protein base carries the savory heart of the casserole.
Step 3: Add Vegetables and Seasonings
Stir in the chopped bell pepper along with the drained diced tomatoes. Sprinkle in the Italian seasoning, and season with salt and pepper to taste. Allow everything to simmer together for about 5 minutes—it’s during this time that the flavors meld and the veggies soften just right. This is also where the dish starts to become beautifully colorful and aromatic.
Step 4: Combine with Roasted Spaghetti Squash
Once the spaghetti squash is tender and cool enough to handle, use a fork to scrape the flesh into long strands directly into the skillet with the turkey mixture. Give everything a good mix to combine so the squash carries the flavors of the meat and veggies throughout every strand. This ensures every bite is bursting with a perfect balance of textures and tastes.
Step 5: Bake with Cheese Topping
Transfer the combined mixture into a greased 9×13-inch baking dish. Sprinkle the shredded mozzarella and grated Parmesan evenly over the top, creating a rich, cheesy blanket. Bake in your preheated oven for 20 to 25 minutes until the cheese is bubbly, melted, and starting to turn a lovely golden brown. The bubbling cheese is that comforting cue that your casserole is ready to be enjoyed.
Step 6: Garnish and Serve
To finish, sprinkle some fresh basil leaves on top for an aromatic, fresh touch. This final flourish not only adds a lovely color contrast but also lifts the overall flavor profile with bright herbal notes that complement the richness below.

Garnishes
Fresh basil is my go-to garnish for this casserole because it adds a pop of color and freshness that brightens every bite. If you want to mix things up, consider a light drizzle of balsamic glaze or a sprinkle of crushed red pepper flakes for a little heat. Even just a dash of extra Parmesan can bring a savory finish to the dish.
Side Dishes
This casserole pairs beautifully with simple sides that don’t overshadow its flavors. A crisp green salad with lemon vinaigrette offers a glowing contrast, while roasted or steamed green vegetables like broccoli or asparagus add extra nutrients and crunch. Garlic bread or crusty artisan bread can round out the meal for anyone wanting a more indulgent, cozy experience.
Creative Ways to Present
Try serving this casserole in individual ramekins for a charming dinner party presentation. Another fun idea is to layer the mixture in clear glass dishes or bowls so guests can see all the colorful layers of spaghetti squash, turkey, and cheese. You can also spoon portions over a bed of sautéed greens or alongside creamy mashed potatoes for a comforting twist.
Make Ahead and Storage
Storing Leftovers
Once cooled, store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. The flavors actually deepen as the casserole rests, making reheated portions taste even better. Just be sure to keep it sealed well to maintain moisture and prevent any fridge aromas from sneaking in.
Freezing
This casserole freezes wonderfully. Portion it into freezer-safe containers or wrap the entire baking dish tightly with foil and plastic wrap. It will keep well for up to 2 months in the freezer. When you’re ready to enjoy, thaw it overnight in the fridge before reheating for the best texture.
Reheating
To reheat, warm the casserole in a preheated oven at 350°F (175°C) for 15 to 20 minutes, or until heated through and the cheese is bubbly again. You can also use a microwave for quicker reheating, but the oven does a better job of maintaining that crispy cheese topping and overall casserole texture.
FAQs
Can I use ground beef instead of ground turkey?
Absolutely! Ground beef will give the casserole a richer flavor and a bit more fat, which some people love. Just keep in mind the dish might be slightly heavier, but the cooking steps remain the same.
Is this recipe gluten-free?
Yes! Since spaghetti squash replaces traditional wheat pasta, this dish is naturally gluten-free, making it perfect for those with gluten sensitivities or anyone seeking a lower-carb alternative.
Can I prepare the spaghetti squash ahead of time?
You can roast and shred the spaghetti squash a day in advance to save time on the day you want to serve the casserole. Keep it wrapped tightly in the refrigerator until ready to mix with the turkey and other ingredients.
How do I know the spaghetti squash is cooked properly?
The squash is done when it’s tender to the touch and you can easily scrape the flesh into strands with a fork. If the strands are mushy, it might be overcooked, so aim for just tender but still slightly firm for the best texture.
Can I add other vegetables to this casserole?
Definitely! Feel free to experiment by adding mushrooms, zucchini, or spinach to increase the veggie count. Just sauté any extra veggies along with the onions and garlic to maintain good texture and flavor balance.
