Chicken Spaghetti is a comforting, creamy casserole that’s packed with tender chicken, melted cheese, and perfectly cooked spaghetti noodles. This dish brings together simple ingredients to make a warm, hearty meal that feels like a big, cozy hug on a plate.
I love making Chicken Spaghetti because it’s so easy to prepare and always hits the spot when I want something satisfying without a lot of fuss. The gooey cheese and tender chicken mixed with the soft noodles is a combo that everyone in my family asks for again and again. Plus, it’s one of those meals that tastes even better the next day, which makes it perfect for leftovers.
My favorite way to serve Chicken Spaghetti is with a simple side salad or some steamed veggies to add a bit of freshness. It’s also fantastic when paired with garlic bread to soak up every bit of that creamy sauce. Whether it’s for a busy weeknight or a casual gathering, this dish always brings smiles to the table and leaves everyone feeling happy and full.
Key Ingredients & Substitutions
Spaghetti noodles: Use regular spaghetti cooked al dente to avoid mushy texture. If you want a gluten-free option, try gluten-free spaghetti or even rice noodles for a different twist.
Chicken: I like using cooked rotisserie chicken for ease. You can also cook and shred your own chicken breasts or thighs. Thighs add more flavor and moisture if you prefer.
Cream soups (mushroom & chicken): These give the dish its creamy base. For a lighter option, use low-fat or cream of celery soup. You can also make your own cream sauce using milk and flour for more control.
Diced tomatoes with green chilies: Adds a bit of tang and mild heat. If you want it less spicy, use plain diced tomatoes and add extra seasonings like paprika or sweet bell peppers.
Cheese: Sharp cheddar adds bold flavor, while Monterey Jack melts beautifully. Feel free to swap with mozzarella or a Mexican cheese blend.
How Do I Make the Sauce Creamy and Flavorful Without It Being Watery?
The key is balancing the soups, broth, and cheeses to get a thick, rich sauce that clings to the noodles perfectly.
- Sauté onions first to add sweetness and depth.
- Carefully measure broth (or water) to avoid thinning the sauce too much.
- Mix half the cheese into the sauce for flavor and melt, then layer the rest on top to create a cheesy crust.
- Don’t overcook the spaghetti—al dente helps it hold up during baking without turning mushy.
- Bake uncovered so the sauce thickens and the top browns slightly.
With these steps, you’ll get a creamy, cheesy sauce that’s perfect every time!
Equipment You’ll Need
- 9×13 inch baking dish – I use this size because it fits everything nicely and bakes evenly.
- Large pot – for cooking the spaghetti noodles so they don’t stick together.
- Skillet or sauté pan – to sauté the onions and add flavor right before mixing everything.
- Mixing bowls – for combining all the ingredients without making a mess.
- Measuring cups and spoons – to get the right amount of ingredients every time.
- Cheese grater – for shredding fresh cheese, if you prefer it freshly shredded.
- Oven – to bake and get that bubbling, cheesy top.
Flavor Variations & Add-Ins
- Use cooked turkey or ham instead of chicken for a different meat flavor.
- Mix in sautéed peppers or spinach for extra veggies and color.
- Try different cheeses like pepper jack or mozzarella for a milder or spicier taste.
- Add a teaspoon of smoked paprika or Cajun seasoning to give it a smoky or spicy kick.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare, 25-30 minutes to bake, and a few minutes to cool before serving. In total, set aside around 45 minutes for making this delicious chicken spaghetti.
Step-by-Step Instructions:
1. Prepare the Oven and Pasta:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish to prevent sticking. Then, cook the spaghetti noodles according to the package instructions until they are tender but still firm (al dente). Drain the noodles and set them aside.
2. Sauté the Onions:
While the pasta cooks, heat the butter or oil in a skillet over medium heat. Add the chopped onions and sauté them until they become soft and translucent, about 3-5 minutes. This adds a nice flavor base to your dish.
3. Mix the Sauce Ingredients:
In a large mixing bowl, combine the cooked chicken, diced tomatoes with green chilies (including the juice), cream of mushroom soup, cream of chicken soup, chicken broth, sautéed onions, garlic powder, onion powder, chili powder, salt, and pepper. Stir everything well to mix the flavors together.
4. Add Cheese and Pasta:
Gently fold half of the shredded cheddar and Monterey Jack cheeses into the chicken mixture. Then, add the cooked spaghetti noodles and stir carefully until all the noodles are coated with the creamy mixture.
5. Bake the Chicken Spaghetti:
Pour the combined mixture into the prepared baking dish and spread it evenly. Sprinkle the remaining shredded cheese on top for a golden, cheesy crust. Place the dish in the oven and bake uncovered for 25-30 minutes, or until the cheese is melted and bubbly.
6. Serve and Garnish:
Once baked, remove the dish from the oven and let it cool for a few minutes. Sprinkle freshly chopped parsley on top for a touch of color and freshness. Serve warm, and enjoy!
Can I Use Frozen Chicken for This Recipe?
Yes! Just be sure to fully thaw the chicken before cooking or mixing it into the dish. Thaw in the fridge overnight or use the defrost setting on your microwave, then shred or chop as usual.
Can I Make Chicken Spaghetti Ahead of Time?
Absolutely! Prepare the casserole up to the baking step, cover it tightly, and refrigerate for up to 24 hours. Bake it when ready, adding a few extra minutes to the baking time if it’s cold from the fridge.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for 3-4 days. To reheat, warm gently in the oven or microwave, stirring occasionally for even heating.
Can I Substitute Different Cheeses?
Yes! Feel free to swap in mozzarella, pepper jack, or a Mexican cheese blend if you want a different flavor or melt quality. Just keep the total cheese quantity the same for gooey deliciousness.
