1. Preheat your oven to 375°F. Cook the spaghetti according to package directions until al dente, then drain and set aside.
2. In a large skillet, melt the butter over medium heat. Add the chopped onion and sauté until translucent, about 4-5 minutes. Stir in minced garlic and cook for another 30 seconds.
3. Sprinkle the flour over the cooked onions and garlic, stirring constantly to make a roux. Cook for 1-2 minutes until lightly golden.
4. Slowly whisk in the milk and chicken broth to avoid lumps. Continue whisking until the sauce thickens, about 5 minutes.
5. Remove the skillet from heat, then stir in 1 cup of cheddar cheese, Italian seasoning, smoked paprika, salt, and pepper. Mix until the cheese melts into the creamy sauce.
6. In a large mixing bowl, combine the cooked spaghetti, shredded chicken, and cheese sauce. Stir gently to coat everything evenly.
7. Transfer the mixture into a greased 9×13-inch baking dish. Sprinkle the remaining cheddar and the mozzarella evenly over the top.
8. Bake uncovered for 20–25 minutes, or until the cheese is bubbly and golden brown around the edges.
9. Remove from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley if desired.

Tips for the Best Results

• Use cooked chicken from a rotisserie or leftovers to save time.
• Don’t overcook the pasta; al dente texture prevents a mushy bake.
• For extra flavor, add a pinch of crushed red pepper flakes in the sauce.
• Let the casserole rest after baking to set, making it easier to slice.
• Use a mix of sharp cheddar and mozzarella for the perfect cheese melt and flavor balance.

Storage and Reheating

Store leftover chicken spaghetti bake in an airtight container in the refrigerator for up to 4 days. It reheats well in the oven or microwave—just cover with foil when reheating in the oven to keep the moisture.

If you want to freeze it, wrap the casserole tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the fridge before reheating thoroughly.

Frequently Asked Questions

Can I use different types of cheese?

Absolutely! While sharp cheddar and mozzarella provide great flavor and meltability, you can experiment with Monterey Jack, Colby, or even pepper jack for a spicy kick.

Is it okay to substitute cream for milk?

You can substitute half-and-half or heavy cream for milk for an even richer and creamier sauce, but you might want to reduce the butter slightly to balance the fat content.

Can I make this recipe vegetarian?

Yes, simply omit the chicken and add extra vegetables like mushrooms, bell peppers, or spinach. You may also want to use vegetable broth instead of chicken broth for the sauce.

How can I make this recipe ahead of time?

Prepare the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. When ready, bake as directed, adding a few extra minutes if baking from cold.
