Ingredients
Here’s everything you need to make this creamy one-pot chicken spaghetti:
- 1 lb spaghetti noodles, broken in half
- 1 lb boneless, skinless chicken breasts, cut into bite-sized pieces
- 1 medium onion, diced
- 3–4 garlic cloves, minced
- 1 can (10 oz) RoTel diced tomatoes with green chilies, undrained
- 4 oz cream cheese, softened
- 2 cups chicken broth
- 1½ cups milk or heavy cream
- 1 cup shredded cheddar cheese or Mexican blend cheese
- 2 tablespoons olive oil or butter
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- Salt, to taste
- Black pepper, to taste
- Fresh parsley or cilantro, chopped, for garnish
How to Make One Pot Chicken Spaghetti
Step 1: Sear the Chicken
Heat the olive oil or butter in a large pot or Dutch oven over medium-high heat.
Add the bite-sized chicken pieces and season with salt, black pepper, and paprika.
Cook for several minutes, stirring occasionally, until the chicken is golden brown and cooked through.
Remove the chicken from the pot and set it aside.
Step 2: Sauté the Onion and Garlic
Using the same pot, add the diced onion and minced garlic.
Cook for 2–3 minutes, stirring occasionally, until the onion becomes soft and translucent and the garlic is fragrant.
The browned bits left in the bottom of the pot will add extra flavor to the sauce.
Step 3: Add the Liquids and Seasonings
Pour the chicken broth and milk or heavy cream into the pot.
Add the undrained RoTel diced tomatoes with green chilies, Italian seasoning, and garlic powder.
Stir everything together and bring the mixture to a gentle boil.
Step 4: Add the Spaghetti
Add the uncooked spaghetti directly to the pot.
Make sure the noodles are mostly submerged in the liquid. Gently stir and separate the spaghetti to prevent the noodles from sticking together.
Step 5: Simmer the Pasta
Reduce the heat to medium-low and cover the pot.
Let the spaghetti simmer for about 12–15 minutes, stirring occasionally.
Cook until the pasta is tender and has absorbed most of the liquid.
If the pasta needs more liquid before it is fully cooked, add a small splash of chicken broth or milk.
Step 6: Make the Sauce Creamy
Turn off the heat.
Add the softened cream cheese and shredded cheddar cheese.
Stir until both cheeses are completely melted and incorporated into the pasta.
The sauce should become smooth, creamy, rich, and cheesy.
Step 7: Add the Chicken
Return the cooked chicken to the pot.
Gently stir everything together until the chicken is evenly distributed throughout the creamy spaghetti.
Allow the dish to sit for a minute or two so the sauce can thicken slightly.
Step 8: Garnish and Serve
Garnish the chicken spaghetti with freshly chopped parsley or cilantro.
Serve immediately while the pasta is hot, creamy, and cheesy.
Tips for the Best One Pot Chicken Spaghetti
- Cut the chicken into evenly sized pieces so it cooks at the same rate.
- Stir the spaghetti occasionally while simmering to prevent it from sticking to the bottom of the pot.
- Soften the cream cheese before adding it for a smoother sauce.
- Freshly shredded cheese usually melts more smoothly than pre-shredded cheese.
- If the sauce becomes too thick, add a splash of chicken broth or milk.
- Let the pasta rest for a few minutes before serving to allow the sauce to thicken.
- Avoid overcooking the spaghetti because it will continue absorbing the sauce as it sits.

Frequently Asked Questions
Can I Use Rotisserie Chicken?
Yes! Rotisserie chicken is a great shortcut for this recipe.
Simply shred or chop the cooked chicken and add it near the end of cooking. Since the chicken is already cooked, you only need to heat it through.
Can I Use Heavy Cream Instead of Milk?
Absolutely.
Heavy cream creates a richer and creamier sauce, while milk produces a lighter result.
For an especially indulgent version, heavy cream works beautifully with the cream cheese and cheddar.
Can I Use a Different Type of Cheese?
Yes. Monterey Jack, Pepper Jack, mozzarella, Parmesan, or a Mexican cheese blend can all work well.
You can also combine different cheeses to create your preferred flavor and texture.
Can I Make This Recipe Less Spicy?
Yes.
Use mild diced tomatoes instead of RoTel with green chilies, or choose a mild variety.
You can also leave out the jalapeños and red pepper flakes if you’re adding them as optional ingredients.
Can I Add Vegetables?
Definitely!
Bell peppers, mushrooms, spinach, corn, and broccoli are all delicious additions.
Add firmer vegetables earlier in the cooking process and quick-cooking vegetables, such as spinach, closer to the end.
Can I Make One Pot Chicken Spaghetti Ahead of Time?
Yes, but keep in mind that the spaghetti will continue absorbing the sauce as it sits.
When reheating, add a little milk or chicken broth and stir gently to bring back the creamy texture.
For the best texture, this dish is best served fresh.
