How to make chicken spaghetti casserole
- Heat the oven to 350°F. Butter a 9x13-inch baking dish.
- Cook the pasta. Boil spaghetti in salted water until 1 to 2 minutes shy of al dente. Drain well.
- Mix the filling. In a large bowl, stir drained spaghetti, shredded chicken, both cans of soup (or homemade sauce), drained tomatoes, broth, onion, garlic powder, 1½ cups cheddar, salt and pepper until evenly coated.
- Bake. Spread in the dish, cover with foil and bake 25 minutes. Uncover, top with remaining ½ cup cheddar and bake 10 to 15 minutes more until bubbling and the center reaches about 165°F.
- Rest. Let stand 5 to 10 minutes so slices hold together.
If you cook raw chicken from scratch for the shreds, cook it to 165°F before mixing. Wash boards and tools that touched raw poultry in hot, soapy water.
Money-saving tip: a rotisserie chicken plus pantry spaghetti and cheddar feeds a crowd cheaper than takeout trays; freeze half the casserole for another night.

Storing, reheating and freezing
Refrigerate leftovers within 2 hours. USDA guidance says cooked leftovers keep 3 to 4 days in the refrigerator and should be reheated to 165°F. Reheat covered in a 350°F oven with a splash of broth, or microwave single portions until steaming hot.
For freezing, FoodSafety.gov's cold food storage charts list cooked leftovers at about 2 to 3 months for best quality. Wrap tightly. This casserole freezes cleaner than many saucy pastas and fits other freezer meals plans.

Frequently asked questions
What is chicken spaghetti? Chicken spaghetti is a creamy baked casserole of cooked spaghetti, shredded chicken, condensed soup or a homemade cream sauce, cheese and often tomatoes or Rotel. It is a potluck and weeknight classic across much of the South and Midwest.
How do you make chicken spaghetti? Cook spaghetti, shred cooked chicken, stir both with a creamy sauce and cheese, spread in a baking dish and bake until bubbly. Many versions use cream of mushroom or chicken soup plus cheddar. Confirm leftovers reheat to 165°F.
What temperature should chicken spaghetti reach? Use chicken that was already cooked to 165°F, then bake the casserole until hot and bubbling (about 165°F in the center). FoodSafety.gov lists 165°F as the safe minimum for poultry and for reheating leftovers.
Can I use rotisserie chicken? Yes, rotisserie chicken works well in chicken spaghetti. Rotisserie chicken is the fastest path. Shred about 3 cups of meat and skip a separate poaching step. Leftover baked chicken or Instant Pot shredded chicken also works.
Do I have to use canned cream soup? No, you don't have to use canned cream soup in chicken spaghetti. You can make a quick homemade sauce with butter, flour, broth and milk, then stir in cheese. Canned soup is the classic shortcut when you want dinner in the oven faster.
Can I make chicken spaghetti ahead of time? Yes, you can make chicken spaghetti ahead and refrigerate it for up to 24 hours. Assemble the casserole, cover and refrigerate up to 24 hours. Add 5 to 10 minutes of bake time from cold. You can also freeze the unbaked casserole tightly wrapped.
What cheese works best? Sharp cheddar is the classic cheese for chicken spaghetti. A mix of cheddar and Monterey Jack melts smoothly. Velveeta-style cheese appears in many family recipes for extra creaminess.
How do I keep the pasta from getting mushy? Boil spaghetti just to al dente (1 to 2 minutes less than package time) because it keeps cooking in the oven. Drain well so extra water does not thin the sauce.
How long do leftovers last? USDA guidance says cooked leftovers keep about 3 to 4 days in the refrigerator. Reheat to 165°F until steaming hot in the center.
Can you freeze chicken spaghetti? Yes, you can freeze chicken spaghetti for about 2 to 3 months. Freeze tightly wrapped before or after baking for best quality within about 2 to 3 months per FoodSafety.gov cold storage charts. Thaw in the refrigerator overnight before reheating.
How do I plan chicken spaghetti into a week of dinners? The Meal Planner & Grocery List ($3.99) from HomeBase Paper Co. has a weekly menu and an aisle-sorted shopping list, so chicken, spaghetti, cheese and soup land on one trip. Pencil it on a busy night or as a Sunday bake-ahead.
Where can I save my family's chicken spaghetti recipe? The Family Recipe Binder ($6.99) from HomeBase Paper Co. has fillable recipe pages and dividers, so your soup-or-homemade sauce notes and cheese blend stay with your other family casseroles. It prints at home on US Letter paper.
