Step-by-step instructions
Follow these steps in order; they have been rewritten for clarity while preserving the recipe’s original quantities and sequence.
- Boil the spaghetti. Bring a large pot of salted water to a rolling boil. Add 1 lb spaghetti and cook until al dente according to package directions. Reserve about 1/2 cup of the pasta cooking water, then drain the spaghetti in a colander and set aside.
- Prepare the chicken. While the pasta cooks, pat 1 lb chicken cutlets dry with paper towels and season both sides lightly with salt and pepper. In a large skillet, heat 2 tablespoons olive oil over medium-high heat. When the oil shimmers, add the chicken cutlets in a single layer. Cook until golden brown on the bottom, about 3–4 minutes, then flip and cook until the chicken is cooked through and internal temperature reaches 165°F (about another 3–4 minutes depending on thickness). Transfer the cooked cutlets to a plate and let them rest for a few minutes, then slice or chop into bite-sized pieces.
- Sauté the aromatics and peppers. In the same skillet, reduce the heat to medium and add the diced yellow onion (1 cup), 1/2 diced red bell pepper, and 1/2 diced green bell pepper. If the pan looks dry, add a small splash of olive oil. Sauté, stirring occasionally, until the onion is soft and translucent and the peppers have softened, about 5–7 minutes. Scrape up any browned bits from the bottom of the pan for extra flavor.
- Add the green chiles and spices. Stir in the 4 oz canned mild diced green chiles (including any juices), 1 teaspoon cumin, 1/2 teaspoon chili powder, and 1/2 teaspoon garlic powder. Cook for 1–2 minutes to allow the spices to bloom and the chiles to warm through.
- Create the sauce base. Pour in the 16.9 oz jar of Alfredo sauce and 1 cup chicken broth. Stir to combine and bring the mixture to a gentle simmer. Let it cook for 3–4 minutes, stirring occasionally, until the sauce is slightly thickened and the flavors have melded. Taste and adjust seasoning with salt and pepper as needed.
- Combine chicken and spaghetti with the sauce. Return the sliced or chopped chicken to the skillet and stir to coat with the sauce. Add the drained spaghetti, tossing gently to combine everything evenly. If the sauce feels too thick, add a few splashes of reserved pasta water, additional chicken broth, or milk to reach your desired consistency. The goal is a creamy sauce that clings to each strand of spaghetti.
- Melt in the cheese. Reduce the heat to low. Sprinkle 8 oz grated sharp cheddar cheese over the pasta and stir until the cheese is fully melted and the sauce is smooth. If the sauce tightens up too much, add a splash more chicken broth or milk to loosen it.
- Finish and serve. Taste and adjust salt and pepper, then remove the skillet from the heat. Garnish with chopped cilantro if desired. Serve the Cheesy Chicken Spaghetti Recipe immediately while hot and creamy.
Flavor and technique notes
This Cheesy Chicken Spaghetti Recipe balances creaminess and savory spice. A few pointers:
- Reserve pasta water: The starchy cooking water helps bind the sauce to the spaghetti and restore creaminess if it becomes too thick.
- Don’t overcook the chicken: Quick cooking at medium-high heat keeps cutlets tender and juicy.
- Customize heat: Increase the chili powder or add a pinch of cayenne if you like more heat, or use roasted red peppers for a sweeter profile.
- Cheese choice: Sharp cheddar adds tang and depth. You can mix in a softer melting cheese like Monterey Jack for extra silkiness, but keep the total cheese amount at 8 oz to preserve the intended balance.
Serving suggestions
Pair this Cheesy Chicken Spaghetti Recipe with a crisp green salad, steamed vegetables, or a simple cucumber and tomato salad to cut through the richness. A squeeze of fresh lime over individual bowls brightens the flavors, while warm crusty bread makes it feel even more comforting.

Common substitutions
If needed, you can make small swaps without changing the character of the dish:

- Bring a large pot of salted water to a boil and cook the spaghetti according to package directions until al dente; drain and set aside.

Notes

- You can slice regular breasts in half lengthwise to make cutlets.
- Or cut raw chicken into bite-size pieces before browning if preferred.
- Using pre-cooked or rotisserie chicken lets you skip the browning step.
