I made this for dinner on a Tuesday night and my husband asked me to make it again the following Sunday.
That’s it. That’s the story.
Chicken spaghetti is one of those recipes that sounds basic on paper but tastes like something you’d pay $18 for at a sit-down restaurant. It’s creamy, cheesy, packed with flavor, and comes together in under an hour.
And once you try it? Good luck going back to plain marinara.
What You’ll Need
For the Chicken & Pasta
- 1.5 lbs boneless, skinless chicken breasts (or thighs)
- 12 oz spaghetti
- 1 can (10.5 oz) cream of mushroom soup
- 1 can (10.5 oz) cream of chicken soup
- 1 cup sour cream
- 1.5 cups shredded sharp cheddar cheese (divided)
- 1 cup shredded mozzarella cheese
- 1 cup chicken broth
- 1 medium yellow onion, diced
- 1 green bell pepper, diced
- 1 red bell pepper, diced
- 3 cloves garlic, minced
- 2 tbsp butter
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp Italian seasoning
- ½ tsp smoked paprika
- Salt and black pepper to taste
- Optional: ½ tsp red pepper flakes (for a little heat)
Tools You’ll Need
- Large pot (for boiling pasta)
- Large oven-safe skillet or 9×13 baking dish
- Cutting board and sharp knife
- Wooden spoon or silicone spatula
- Cheese grater (always grate your own – more on that below 👇)
- Measuring cups and spoons
- Colander for draining pasta
- Tongs for handling chicken
Pro Tips
These are the things I wish someone had told me before I made this the first time.
1. Cook your chicken in the broth. Poaching the chicken in chicken broth before shredding it makes the meat incredibly juicy and infuses flavor from the inside out. Don’t skip this.
2. Grate your own cheese. Pre-shredded cheese has an anti-caking coating that stops it from melting smoothly. Block cheese, freshly grated, melts into the sauce like a dream. The difference is genuinely shocking.
3. Don’t overcook the pasta. Cook it 2 minutes less than the package directions say. It’ll finish cooking in the oven and you do not want mushy spaghetti. Nobody does.
4. Let the sauce come to room temp before mixing. If you mix cold sour cream straight into a hot pan, it can curdle slightly. Let it sit out for 10-15 minutes first.
5. Cover with foil for the first half of baking. This keeps the moisture in and stops the top from browning too fast before the center is fully heated through. Remove it for the last 10 minutes to get that golden, bubbly cheese top.
How to Make Chicken Spaghetti
Step 1: Cook the Chicken
Place your chicken breasts in a large pot.
Cover with chicken broth (and water if needed to fully submerge) and bring to a gentle boil.
Cook for 15-18 minutes, or until the chicken is cooked through and no longer pink inside. Remove and set aside to cool slightly, then shred using two forks.
Save the broth. You’ll need 1 cup of it for the sauce.
Step 2: Cook the Pasta
In the same pot (or a fresh one), bring salted water to a boil and cook spaghetti 2 minutes less than package directions.
Drain and set aside. Toss with a tiny bit of olive oil so it doesn’t stick together.
Step 3: Sauté the Vegetables
Preheat your oven to 350°F (175°C).
In a large oven-safe skillet or a regular skillet (you’ll transfer to a baking dish after), melt butter over medium heat.
Add the diced onion and both bell peppers. Cook for 4-5 minutes until softened.
Add the garlic and cook for another 60 seconds until fragrant.
Step 4: Build the Sauce
Reduce heat to medium-low.
Add cream of mushroom soup, cream of chicken soup, sour cream, and 1 cup of reserved chicken broth to the skillet.
Stir everything together until smooth and combined.
Add garlic powder, onion powder, Italian seasoning, smoked paprika, salt, pepper, and red pepper flakes if using.
Stir in 1 cup of the shredded cheddar cheese until melted.
Step 5: Combine Everything
Add the shredded chicken and cooked spaghetti to the sauce.
Gently toss everything together until fully coated. Take a second here to taste and adjust seasoning.
Step 6: Bake It
Transfer to a greased 9×13 baking dish (or leave in your oven-safe skillet).
Top with remaining cheddar cheese and all of the mozzarella.
Cover tightly with foil and bake at 350°F for 25 minutes.
Remove the foil and bake for another 10-15 minutes until the cheese is golden and bubbling.
Let it rest for 5 minutes before serving. Yes, this matters. The sauce thickens up a bit as it sits.
Substitutions and Variations
Not into something on the list? Easy swaps:
- Chicken thighs instead of breasts – thighs are fattier and stay even juicier after shredding
- Rotisserie chicken – already cooked, already shredded, cuts your time in half
- Cream of celery soup instead of cream of mushroom if you’re not a mushroom fan
- Greek yogurt instead of sour cream for a lighter version
- Gluten-free pasta works perfectly here – just watch your cook time
- Pepper jack cheese instead of cheddar if you want more heat
- Velveeta (8 oz) instead of shredded cheeses if you want an ultra-creamy, old-school Southern version
Want to make it spicier? Add a can of diced green chiles or a few dashes of hot sauce into the sauce mixture.
Make-Ahead Tips
This dish is absolutely made for meal prep.
Assemble and refrigerate: Put it all together in the baking dish, cover tightly with foil, and refrigerate for up to 24 hours before baking. Add 10-15 minutes to the baking time since it’ll be going in cold.
Freeze before baking: Assemble, cover tightly with foil + plastic wrap, and freeze for up to 3 months. Thaw overnight in the fridge, then bake as directed.
Freeze after baking: Cool completely, portion into airtight containers, and freeze for up to 3 months. Reheat in the microwave or oven.

Want to lighten it up? Use reduced-fat sour cream, low-sodium soups, and part-skim mozzarella. Still delicious, just a bit lighter.
Meal Pairing Suggestions
This is already a full meal on its own, but if you want to round it out:
- A simple green salad with vinaigrette (to cut through the richness)
- Garlic bread or crusty rolls
- Roasted broccoli or steamed green beans on the side
- A glass of crisp white wine (Sauvignon Blanc pairs really well)
Leftovers and Storage
Refrigerator: Store in an airtight container for up to 4 days.
Reheating: Add a splash of chicken broth or water before microwaving. This keeps it from drying out. Stir halfway through heating.
Oven reheating: Cover with foil and warm at 325°F for 15-20 minutes. Remove foil for the last 5 minutes to re-melt the cheese.
Fair warning: leftovers taste even better the next day. The flavors deepen overnight in a way that’s honestly a little unfair to day-one dinner guests.
Frequently Asked Questions
Can I use a different type of pasta? Yes! Linguine, fettuccine, or even penne work here. Just stick to a shape that’ll hold the sauce well.
Can I make this without canned soup? You can make a homemade cream sauce using butter, flour, chicken broth, and milk. It takes a bit more effort but tastes incredible. Use about 2 cups of homemade cream sauce total.
My sauce feels too thick. What do I do? Add a splash of chicken broth or milk and stir until it loosens up. The pasta will absorb liquid as it bakes, so slightly saucier is better going in.
Can I use turkey instead of chicken? Yes, leftover Thanksgiving turkey is genuinely amazing in this recipe.
Is this kid-friendly? Very. Leave out the red pepper flakes and it’s mild, creamy, cheesy pasta. Most kids go absolutely wild for it.
Do I have to use both cream of mushroom and cream of chicken soups? You can use two cans of the same type if you prefer. Two cans of cream of chicken gives a slightly lighter flavor; two cans of cream of mushroom is richer and more savory.
Wrapping Up
Chicken spaghetti is comfort food that actually delivers.
It’s not fussy. It’s not expensive. It feeds a crowd, works as leftovers for days, and makes your kitchen smell incredible while it’s baking.
The kind of meal where people come into the kitchen before you even call them to eat.
