Ingredients You’ll Need
The ingredients for this Baked Spaghetti Squash and Cheese Recipe are wonderfully straightforward yet essential for building its luscious texture and vibrant flavor.

- 2 cups skim milk: Keeps the cheese sauce smooth and lighter without losing creaminess.
- 1 cup fat-free chicken broth: Adds savory flavor and balances the richness (use vegetable broth to keep it vegetarian).
- Salt and pepper: Season to taste for the perfect burst of flavor.

How to Make Baked Spaghetti Squash and Cheese Recipe
Step 1: Cook Spaghetti Squash
Start by preheating your oven to 375°F. Cut two small spaghetti squashes in half lengthwise and scoop out the seeds. Place them cut-side down on a baking sheet and bake for about one hour until the flesh is tender and can easily be shredded with a fork. Once baked, scrape out the strands carefully, then squeeze out any excess moisture – this step ensures your casserole won’t be watery.
Step 2: Make the Cheese Sauce
While your squash is baking, melt the butter and olive oil together in a saucepan over medium heat. Add minced onions and cook until soft, about two minutes. Then stir in the flour and cook for another 3-4 minutes, stirring constantly. Gradually whisk in the milk and chicken broth, bringing the sauce to a gentle boil before reducing the heat to let it thicken for about 2 minutes. Don’t forget to season with salt and pepper, which makes the flavors pop.
Step 3: Combine Ingredients
Remove the sauce from heat and stir in the cheddar cheese until it melts completely, creating a velvety, rich cheese sauce. Fold in the cooked spaghetti squash strands and fresh baby spinach, which wilts down beautifully in the residual heat, adding a lovely touch of color and nutrition.
Step 4: Bake to Perfection
Pour the cheesy spaghetti squash mixture into a greased baking dish and sprinkle the top with grated Parmesan cheese. Bake in the preheated oven for 25-30 minutes or until the dish is bubbly and the top has turned a gorgeous golden brown. This final step melds all the flavors together and creates that irresistible crust on top we all love.
How to Serve Baked Spaghetti Squash and Cheese Recipe
Garnishes
The Baked Spaghetti Squash and Cheese Recipe is wonderful as is, but a sprinkle of freshly chopped parsley or basil adds a burst of fresh color and herbaceous brightness that balances the richness. A dash of crushed red pepper flakes can also bring a little pleasant heat to the dish.
Side Dishes
This cheesy bake pairs beautifully with lighter sides to round out your meal. Consider serving it alongside a crisp mixed green salad with a tangy vinaigrette or some roasted Brussels sprouts. For a heartier meal, garlic bread or a crusty baguette complements the creamy texture perfectly.
Creative Ways to Present
For a fun twist, try serving the Baked Spaghetti Squash and Cheese Recipe in individual ramekins or hollowed-out spaghetti squash shells for a rustic, elegant presentation. You can also sprinkle toasted breadcrumbs on top before baking for extra crunch or mix in some cooked mushrooms or sun-dried tomatoes to personalize the flavors.
Make Ahead and Storage
Storing Leftovers
Store any leftover Baked Spaghetti Squash and Cheese in an airtight container in the refrigerator for up to four days. Covering it well helps maintain the creamy texture while keeping it fresh and ready for a quick reheat.
Freezing
This recipe freezes well if you want to prep ahead. Portion it into freezer-safe containers and freeze for up to two months. Thaw overnight in the fridge before reheating to retain its smooth, cheesy consistency without becoming watery.
Reheating
Reheat leftovers gently in the oven at 350°F until warmed through, which helps maintain the dish’s texture and prevents the cheese from separating. Microwave reheating works in a pinch but stir occasionally for even warmth and to avoid drying out the top layer.
FAQs
Can I use a different type of cheese?
Absolutely! While mild cheddar creates that classic cheesy flavor, you can experiment with mozzarella, Gruyère, or a sharp white cheddar for variations. Just choose cheeses that melt well to keep that creamy texture.
Is this recipe gluten-free?
It can be! Simply swap the all-purpose flour for a gluten-free flour blend of your choice when making the cheese sauce. This substitution keeps the dish just as creamy and delicious.
How do I know when the spaghetti squash is done baking?
When the flesh is fork-tender and easily separates into strands, your spaghetti squash is perfectly cooked. It should feel soft to the touch when you press the outer shell gently.
Can I make this recipe vegetarian?
Yes, replace the chicken broth with vegetable broth to keep the dish vegetarian-friendly while maintaining all the savory flavor you love. The cheese sauce will still be rich and satisfying.
What variations can I add to the recipe?
This recipe is a great canvas for added flavors—think cooked bacon or sausage for meat lovers, sautéed mushrooms for earthiness, or sun-dried tomatoes for a tangy pop. You can also mix in herbs like thyme or oregano to elevate the taste.

- Combine Cheese and Vegetables: Remove the saucepan from heat and stir in the mild cheddar cheese until fully melted and smooth. Fold in the spaghetti squash strands and baby spinach to evenly incorporate them into the sauce.
- Assemble and Bake: Pour the cheese and squash mixture into a greased baking dish. Sprinkle the grated Parmesan cheese evenly on top. Bake at 375°F (190°C) for about 25 to 30 minutes, or until the casserole is bubbly and the top is golden brown.
