Spaghetti Squash Casserole Ingredients
• Get ready to savor this delicious Spaghetti Squash Casserole with these wholesome ingredients!
For the Casserole
- Spaghetti Squash – This base ingredient provides a pasta-like texture, so ensure it’s well-cooked and thoroughly drained to prevent excess moisture.
- Coconut or Avocado Oil – Ideal for sautéing the meat and greasing the dish, it offers healthy fats; feel free to substitute with olive oil if you prefer.
- Ground Chicken or Turkey – The main protein source for this dish; you can easily replace it with lean beef for a slightly different flavor profile.
- Yellow Onion – Adds a natural sweetness and depth to the casserole, but you can opt for a white onion if you desire a sharper taste.
- Salt – Essential for enhancing all the flavors; adjust the amount to suit your taste.
- Garlic – Fresh is best for a rich flavor, but garlic powder can work as a substitute in a pinch.
- Italian Seasoning – This provides the classic herb profile typical of pizza; fresh herbs can elevate the flavor even further.
- Mozzarella Cheese – Melts beautifully and creates that gooey texture; use part-skim for a lighter result or non-dairy cheese for a vegan option.
- Tomato Sauce – Acts as the flavorful base; a no-sugar-added variety is a healthier choice.
- Pepperonis – These add a classic pizza element; look for nitrate-free varieties for a healthier option.
- Fresh Basil (Optional) – Offers a pop of freshness as a garnish; you can substitute with parsley or skip it if you don’t have any on hand.
This Spaghetti Squash Casserole will transform your dinner routine into a delightful and nutritious feast!
Step‑by‑Step Instructions for Spaghetti Squash Pizza Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that by the time you assemble your Spaghetti Squash Pizza Casserole, the oven is at the perfect temperature to cook the dish evenly and thoroughly.
Step 2: Sauté the Meat
In a large skillet, heat a tablespoon of coconut or avocado oil over medium-high heat. Add the ground chicken or turkey along with the diced onion, minced garlic, and a pinch of salt. Cook until the meat is browned and the onions are translucent, which should take about 8 minutes. Remove the skillet from heat and set aside.
Step 3: Prepare the Casserole Mix
In a large mixing bowl, combine the well-drained spaghetti squash with the sautéed meat mixture. Pour in the tomato sauce, add 1½ cups of mozzarella cheese, and sprinkle in the Italian seasoning. Stir everything together until fully combined, ensuring that every strand of spaghetti squash is coated with that delicious mixture.
Step 4: Bake the Initial Layer
Transfer the combined mixture into a greased 9×13-inch casserole dish, spreading it evenly. Place the dish in the preheated oven and bake for 20 minutes. You’ll know it’s ready when the mixture is heated through and slightly bubbling at the edges.
Step 5: Add Toppings
Carefully remove the casserole from the oven. Sprinkle the remaining mozzarella cheese evenly over the top, and arrange pepperoni slices on top to give that classic pizza appearance. Return the dish to the oven for an additional 5–7 minutes, or until the cheese is melted and golden brown.
Step 6: Cool and Garnish
Once the cheese topping is perfectly melted, take the casserole out of the oven and let it cool for about 5–10 minutes. This resting time helps set the layers and makes serving easier. If desired, garnish with fresh basil leaves to add a pop of color and flavor before serving your delightful Spaghetti Squash Pizza Casserole.

Spaghetti Squash Pizza Casserole Recipe FAQs
How do I choose a ripe spaghetti squash?
Absolutely! When selecting a spaghetti squash, look for one that feels heavy for its size, with a hard, textured skin free of dark spots or blemishes. A good squash should be a vibrant yellow color, so avoid any that have green patches, as this could indicate it’s not fully ripe.
What’s the best way to store leftover spaghetti squash casserole?
The more the merrier! Store your leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, pop it back in the oven at 350°F (175°C) for about 15 minutes. This helps maintain its texture and avoids a soggy dish.
Can I freeze my spaghetti squash casserole?
Yes, you can! To freeze your casserole, first allow it to cool completely, then transfer it to an airtight container or freezer-safe bag. It can be frozen for up to 3 months. When ready to enjoy, simply thaw it overnight in the fridge and reheat at 350°F (175°C) until heated through, about 20-30 minutes.
What should I do if my casserole turns out too watery?
No worries! If you find yourself with a watery casserole, it could be due to excess moisture in the spaghetti squash. Make sure you’re thoroughly draining it after cooking; I recommend placing the squash in a clean kitchen towel and squeezing out any remaining water. Additionally, you can try adding a little cornstarch to the mix before baking to help thicken it up.
Is this casserole safe for dogs?
It’s wonderful that you’re thinking about your furry friends! While the primary ingredients are not toxic to dogs, it’s best to keep this casserole away from them due to the garlic, onions, and cheese, which can upset a dog’s stomach. Always consult with your vet before sharing human food with pets.
Can I adapt this recipe for a vegetarian diet?
Very much so! To make this casserole vegetarian-friendly, you can substitute the ground turkey or chicken with cooked lentils or sautéed mushrooms. This not only keeps the dish hearty but also ensures that it still satisfies all those pizza cravings without the meat!
