Quick, saucy, and cheesy, this dinner checks all the boxes: it’s simple to make, uses only one pot, and yields a crowd-pleasing meal with tender chicken and silky pasta. The sauce is thickened with a bit of flour and enriched with reduced fat cream cheese for a luscious texture without being overly heavy.

Equipment

Large, heavy-bottomed pot or deep skillet with lid; wooden spoon or spatula; knife and cutting board; measuring cups and spoons.

Before you start

Trim any excess fat from the chicken breasts and pat them dry. Cut the onion into small dice and mince the garlic. If you choose to use the optional tomato garnish, seed and dice it now so it’s ready at the end.

Step-by-step instructions

Heat the oil: Place a large, heavy-bottomed pot or deep skillet over medium-high heat. Add 2 Tablespoons olive oil and let it warm until shimmering but not smoking.
Sear the chicken: Add the 1 pound boneless skinless chicken breasts to the pot. Cook for 4–5 minutes per side until the exterior is golden brown and the chicken is mostly cooked through. Remove the chicken to a plate and set aside. (It will finish cooking later in the sauce.)
Sauté the aromatics: Reduce the heat to medium. Add the ¼ cup diced yellow onion to the pot and sauté for 2–3 minutes, stirring occasionally, until the onion is soft and translucent. Add the 3 cloves garlic (minced) and cook for 30–60 seconds more, until fragrant.
Make the roux: Sprinkle ¼ cup all-purpose flour over the softened onions and garlic. Cook, stirring constantly, for 1–2 minutes to remove the raw flour taste and to form a light roux.
Add liquids and seasonings: Slowly whisk in 2 cups 2% milk and 2 cups chicken broth, bringing the mixture to a gentle simmer as you stir so it becomes smooth. Stir in ½ teaspoon salt and ¼ teaspoon black pepper. Continue stirring until the sauce begins to thicken slightly.
Add Rotel and cream cheese: Stir in the entire 10 ounce can mild Rotel (undrained). Cut the 4 ounces reduced fat cream cheese into chunks and add them to the pot, stirring until the cheese melts and the sauce is creamy and cohesive.
Return chicken and add pasta: Nestle the seared chicken breasts back into the simmering sauce. Scatter the 8 ounces angel hair pasta into the pot, pressing it down gently so it is mostly submerged in the liquid. If the pasta isn’t fully covered, add a little extra chicken broth or water—just enough so the noodles can cook evenly.
Simmer until pasta is tender: Bring the pot to a low boil, then reduce heat to maintain a gentle simmer. Cover and cook for about 8–10 minutes, stirring once or twice to prevent sticking and to help the pasta absorb the sauce. Angel hair cooks quickly; check doneness after 8 minutes. The chicken should reach a safe internal temperature and be tender.
Shred the chicken: Remove the cooked chicken breasts to a cutting board. Use two forks to shred the chicken into bite-sized pieces, then return the shredded chicken to the pot and stir to distribute it through the pasta and sauce.
Finish with cheese: Sprinkle 1 cup shredded Mexican cheese over the top of the pasta and stir until melted and evenly combined. Taste and adjust seasoning with a pinch more salt and pepper if needed.
Serve and garnish: Spoon the One Pot Chicken Spaghetti into bowls. If you like a bright, fresh touch, top each serving with the 1 tomato diced and seeded (optional). Serve hot and enjoy.

Troubleshooting and tips

If the sauce thickens too much before the pasta is cooked, add up to ¼ cup extra chicken broth or milk and stir to loosen it.
Angel hair pasta cooks quickly. Keep an eye on it after the first 6–8 minutes to avoid overcooking and turning mushy.
For a milder dish, drain a small portion of the Rotel before adding; for more zing, leave it undrained as written.
If you prefer a smoother sauce, break the cream cheese into very small pieces so it melts faster and more evenly.

Make-ahead and storage

This recipe stores well. Cool leftovers completely, then refrigerate in an airtight container for up to 3 days. Reheat gently on the stovetop over low heat with a splash of milk or broth to loosen the sauce, stirring frequently. You can also freeze portions for up to 2 months; thaw overnight in the refrigerator before reheating.

Variations

Vegetable boost: Stir in a cup of baby spinach or a cup of frozen peas during the last few minutes of cooking for added color and nutrients.
Different cheese: Swap the Mexican cheese for cheddar or a blend of Monterey Jack and cheddar for a different flavor profile.
Spice it up: Use a can of regular Rotel instead of mild, or add a pinch of crushed red pepper when adding the Rotel if you like heat.

Final thoughts

This One Pot Chicken Spaghetti proves that fuss-free cooking can still be indulgent. With a creamy, savory sauce, tender shredded chicken, and quick-cooking angel hair, it’s a reliable weeknight winner. Garnish with fresh tomato if you want a pop of color and freshness, plate it up, and enjoy a satisfying meal with minimal cleanup.

Ingredients

1 pound boneless skinless chicken breasts trimmed and cut into 1-inch cubes
2 tablespoons olive oil
1/4 cup yellow onion diced
3 cloves garlic minced

2 cups 2% milk
2 cups chicken broth
1/2 teaspoon salt
1/4 teaspoon black pepper
10 ounce can mild Rotel
4 ounces reduced fat cream cheese cut into bite-size pieces
8 ounces angel hair pasta uncooked
1 cup shredded Mexican cheese
1 tomato diced and seeded, optional

Instructions

Trim excess fat from the chicken and cut into 1‑inch cubes.
Heat the olive oil in a large skillet over medium heat. Add the chicken and diced onion and cook, stirring occasionally, until the chicken is cooked through, about 6–8 minutes.
During the last minute of cooking, add the minced garlic and cook until fragrant, about 1 minute. Remove the chicken and set aside.
Reduce heat to low and pour 1 cup of the milk into the skillet. Whisk in the flour until smooth to form a roux.
Slowly whisk in the remaining milk and the chicken broth, keeping the sauce smooth.
Add the salt and black pepper, bring the mixture to a gentle boil over medium heat, and cook until slightly thickened, whisking frequently.
Stir in the can of mild Rotel and the uncooked angel hair pasta. Increase heat to high to bring the mixture to a boil, then reduce to medium‑low, cover, and cook 8–10 minutes, stirring occasionally, until the pasta is al dente.
Add the cream cheese pieces and shredded Mexican cheese to the skillet and stir until melted and creamy.
Return the cooked chicken to the skillet, stir to combine, and heat through.
Garnish with the diced, seeded tomato if using and serve hot.
