Step-by-Step Instructions
Cook the Spaghetti Boil the spaghetti in salted water until al dente, about 9 minutes. Drain and set aside.
Sauté the Onion, Celery, and Bell Pepper Melt the butter in a large saucepan over medium heat. Add the diced onion, celery, and bell pepper, and cook for 5 to 6 minutes, stirring occasionally, until softened.
Make the Roux Sprinkle the flour over the softened vegetables and stir constantly for 1 minute to cook off the raw flour taste.
Build the Cheese Sauce Slowly pour in the chicken broth and milk, whisking constantly to prevent lumps. Bring to a gentle simmer and cook for 4 to 5 minutes until thickened.
Melt in the Cheese Reduce the heat to low and stir in 1 1/2 cups of the shredded cheddar a handful at a time until the sauce turns smooth and glossy. Season with paprika, salt, and pepper.
Combine the Chicken and Pasta Add the shredded chicken and cooked spaghetti directly into the sauce. Fold gently until everything is evenly coated.
Transfer to the Baking Dish Spread the chicken spaghetti mixture into the prepared baking dish using a spatula, smoothing it into an even layer.
Top with Cheese Sprinkle the remaining 1/2 cup shredded cheddar evenly across the top.
Bake Until Bubbly Bake at 375°F for 20 to 25 minutes until the cheese is melted and the edges are bubbling.
Garnish and Serve Let the dish rest for 5 minutes before serving, finishing with a sprinkle of chopped parsley.
Pro Tips for Best Results
- Break the spaghetti in half before boiling so it’s easier to mix evenly into the sauce.
- Whisk the broth and milk in slowly to avoid a lumpy sauce.
- Use freshly shredded cheese rather than pre-shredded for a smoother melting sauce.
- Let the casserole rest a few minutes after baking so it firms up slightly before serving.
- Rotisserie chicken saves significant time without sacrificing flavor in this recipe.
Common Mistakes to Avoid
- Overcooking the spaghetti: it continues to cook slightly in the oven, so keep it al dente going in.
- Skipping the roux step: without it, the sauce can turn thin and separate during baking.
- Using pre-shredded cheese: anti-caking coatings can make the sauce grainy, so grate your own when possible.
- Not resting before serving: cutting immediately can cause the sauce to run, so let it rest 5 minutes first.
What to Serve With
- Garlic bread: perfect for scooping up any extra cheese sauce left on the plate.
- A simple side salad: crisp greens with a light vinaigrette balance the richness of the casserole.
- Steamed green beans: adds a light vegetable side that pairs well with the creamy pasta.
Storage and Reheating
- Refrigerator: store in an airtight container for up to 4 days.
- Freezer: freeze in a covered dish for up to 2 months.
- Reheating: warm covered in a 350°F oven for 15 to 20 minutes, or microwave individual portions until heated through.
