Let’s Get Started
Follow these easy steps to make your own Chicken Spaghetti Bake:
Cook the Spaghetti
Start by cooking the spaghetti according to the package instructions until al dente. Drain, rinse, and set aside.Sauté the Veggies
In a large skillet, melt 1 tablespoon of butter over medium heat. Add the chopped onion and green bell pepper, and sauté for 3–4 minutes until softened. Add the minced garlic and cook for another 30 seconds until fragrant.Prepare the Creamy Sauce
In a large mixing bowl, combine the cream of mushroom soup, cream of chicken soup, chicken broth, sour cream, salt, pepper, and paprika. Stir until everything is smooth and well blended.Mix the Casserole Base
Add the cooked spaghetti, shredded chicken, sautéed veggies, and half of the shredded cheeses (1/2 cup each of cheddar and mozzarella) to the sauce. Toss everything together until evenly coated.Transfer and Top
Pour the mixture into a greased 9×13-inch baking dish. Spread evenly, then sprinkle the remaining cheddar and mozzarella cheese on top.Bake
Bake in a preheated oven at 350°F (175°C) for 25–30 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.Cool and Serve
Let the casserole rest for 5–10 minutes before serving. This helps it firm up and makes it easier to slice and serve.

FAQs
Can I make this ahead of time?
Yes! Assemble the casserole, cover, and refrigerate for up to 24 hours before baking. You may need to add 5–10 extra minutes to the bake time if starting from cold.
Is it okay to use canned chicken?
Absolutely. While fresh or rotisserie chicken adds more flavor, canned chicken works in a pinch—just drain it well before adding.
Can I leave out the cream of mushroom soup?
You can swap it for another can of cream of chicken, or use cream of celery instead if you prefer.
What’s the best cheese combo?
Cheddar gives sharp flavor, while mozzarella adds stretch. Feel free to use Monterey Jack, Colby, or pepper jack for different twists.
How do I keep it from drying out?
Make sure your sauce mixture is well combined and creamy. Cover with foil if the cheese starts browning too quickly during baking.
