How to Make Creamy Spinach and Spaghetti Squash Casserole
-
Preheat oven: Begin by preheating your oven to 400°F. This step ensures your spaghetti squash roasts perfectly!
-
Prepare squash: Brush the cut sides of the spaghetti squash with extra virgin olive oil, then season with ½ teaspoon kosher salt and ¼ teaspoon black pepper for added flavor.
-
Roast squash: Place the squash cut-side down on a parchment-lined baking sheet. Roast for 35-40 minutes until the flesh becomes tender and can easily be shredded with a fork.
-
Wilt spinach: While the squash is roasting, wilt 16 ounces of fresh spinach in a large skillet over medium heat. It should reduce by half in about 3 minutes.
-
Drain spinach: Transfer the cooked spinach to a colander and press out any excess liquid using the back of a spoon. This step keeps your casserole from getting too watery.
-
Sauté garlic: In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Add 3 minced garlic cloves and sauté until fragrant, about 1 minute.
-
Make cream base: Add 8 ounces of cream cheese and ½ cup of heavy cream to the skillet, whisking until the mixture is smooth and well combined.
-
Incorporate cheese: Stir in ¼ cup of grated Parmesan cheese along with the remaining ½ teaspoon salt and ¼ teaspoon black pepper to enhance the flavor profile of your sauce.
-
Fold in spinach: Remove the skillet from heat and gently fold in the wilted spinach, making sure it is evenly incorporated in the creamy mixture.
-
Shred squash: Once roasted, use a fork to shred the spaghetti squash flesh into strands. Transfer these strands to a 9×13 baking dish.
-
Combine ingredients: Pour the spinach cream sauce over the shredded squash, tossing everything together so that the sauce coats the squash evenly.
-
Add cheese topping: Sprinkle ½ cup of shredded mozzarella cheese over the top of the casserole. This will create a deliciously cheesy crust as it bakes!
-
Bake casserole: Place the dish in the oven and bake at 375°F for 15-18 minutes, until the casserole is bubbly and the cheese is golden brown on top.
-
Rest before serving: Allow the casserole to rest for 5 minutes before serving. This gives the sauce time to thicken and makes serving easier.
Optional: Garnish with fresh chopped herbs for a burst of color and flavor.

Creamy Spinach and Spaghetti Squash Casserole Recipe FAQs
What is the best way to choose a ripe spaghetti squash?
Absolutely! When choosing a spaghetti squash, look for one that feels heavy for its size and has a smooth, firm skin. Avoid any squash with dark spots or soft spots, as these may indicate overripeness.
How should I store leftover Creamy Spinach and Spaghetti Squash Casserole?
For optimal freshness, store your leftovers in an airtight container in the fridge for up to 3 days. Allow the casserole to cool completely before sealing it to maintain the best texture.
Can I freeze Creamy Spinach and Spaghetti Squash Casserole?
Yes, you can freeze this delightful dish! Portion it out into airtight containers or freezer bags, ensuring they are well-sealed to prevent freezer burn. It will stay fresh for up to 3 months. To reheat, simply thaw overnight in the fridge before warming it up—either in the oven at 350°F for 20-25 minutes or in the microwave until heated through.
What can I do if my spinach cream sauce is too watery?
If you find your sauce is too watery, don’t worry! You can thicken it by simmering it gently on low heat. Alternatively, mix in a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon cold water) and stir until it reaches your desired consistency. Also, make sure to press out excess liquid from the wilted spinach in the colander to help prevent this issue from happening in the first place.
Are there any dietary considerations for this recipe?
Very much so! If you have allergies, be cautious with the cream cheese and butter, as they contain dairy. For a dairy-free version, try using a plant-based cream cheese and coconut milk. Additionally, since this dish contains spinach, it may not be suitable for dogs, as they can be sensitive to oxalates in leafy greens. Always consult with your vet before sharing any human food with your pets!
