1. Creamy Chicken Spaghetti Recipe (Yield: 8 Servings)
Ingredients
- 1½ pounds boneless chicken breast, cooked and shredded (or more if desired)
- 16 ounces spaghetti, broken into 2-inch pieces
- 2 (10.75-ounce) cans condensed cream of chicken soup (21.5 ounces total)
- 1 (10-ounce) can diced tomatoes and green chilies (RoTel)
- 6 ounces cream cheese
- 3 cups shredded Cheddar cheese, divided (about 12 ounces)
- ¼ cup heavy cream (or milk)
- 1 cup frozen peppers and onions mix, or diced fresh peppers and onions
Instructions
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter and set it aside.
Bring a large pot of salted water to a boil. Add the broken spaghetti pieces and cook until just al dente according to the package directions. The pasta will continue cooking in the oven, so avoid overcooking it. Drain well and set aside.
While the pasta cooks, place a large skillet or Dutch oven over medium heat. Add the frozen peppers and onions mixture and cook for 4 to 5 minutes until softened. If using fresh vegetables, cook until the onions become translucent and the peppers are tender.
Reduce the heat to medium-low. Add the cream cheese, cream of chicken soup, RoTel tomatoes with their juices, and heavy cream. Stir frequently until the cream cheese has completely melted and the sauce becomes smooth and creamy.
Add 2 cups of the shredded Cheddar cheese to the sauce, stirring until fully melted. The sauce should be thick, creamy, and evenly blended.
Fold the shredded chicken into the cheese sauce and stir until every piece is coated.
Add the cooked spaghetti and gently toss until the pasta is completely covered with the creamy sauce. Continue mixing until all of the ingredients are evenly distributed.
Transfer the mixture into the prepared baking dish and spread it into an even layer. Sprinkle the remaining 1 cup of shredded Cheddar cheese evenly over the top.
Bake uncovered for 25 to 30 minutes, or until the casserole is hot throughout and the cheese is melted and bubbly. For a lightly browned cheese topping, switch the oven to broil for the last 2 to 3 minutes, watching carefully to prevent burning.
Remove the casserole from the oven and let it rest for about 10 minutes before serving. This allows the sauce to thicken slightly and makes serving much easier.
2. Tips for Perfect Creamy Chicken Spaghetti
Cook the spaghetti just until al dente so it keeps its texture after baking.
Use freshly shredded Cheddar cheese whenever possible. It melts more smoothly than pre-shredded cheese, which often contains anti-caking agents.
Shred the cooked chicken into bite-sized pieces so it mixes evenly throughout the casserole.
Allow the cream cheese to soften before adding it to the sauce. It melts faster and creates a smoother texture.
Let the casserole rest for about 10 minutes after baking. This helps the creamy sauce set and makes each serving hold together better.
If you’d like an extra golden cheese topping, broil the casserole for the final 2 to 3 minutes while watching it closely.
3. Frequently Asked Questions
Can I make Creamy Chicken Spaghetti ahead of time?
Yes. Assemble the casserole up to one day in advance, cover it tightly, and refrigerate. When you’re ready to bake, let it sit at room temperature for about 20 minutes, then bake as directed. You may need to add a few extra minutes to the baking time.
Can I freeze this casserole?
Absolutely. Allow the assembled casserole to cool completely, then wrap it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking or reheating.
Can I use rotisserie chicken instead of cooked chicken breast?
Yes. Rotisserie chicken is an excellent shortcut that adds plenty of flavor while saving preparation time. Simply remove the skin and shred the meat before adding it to the sauce.
Can I make this recipe a little spicier?
Yes. Stir in diced jalapeños, a pinch of cayenne pepper, crushed red pepper flakes, or use hot RoTel instead of the original variety for extra heat.
What can I serve with Creamy Chicken Spaghetti?
This casserole pairs well with garlic bread, dinner rolls, Caesar salad, roasted asparagus, steamed green beans, broccoli, or a simple garden salad for a balanced meal.
