Before you start
Before starting, ensure all ingredients are measured and ready to go. Dice the chicken into uniform, bite-sized pieces to ensure they cook at the same rate. Have your colander positioned near the sink to drain the pasta quickly, and grate the cheddar cheese if not using a pre-shredded variety.
Having everything within reach will make the cooking process smooth and efficient, as the sauce comes together quickly once the heat is applied to the skillet.

Instructions
Cooking the base
- Prepare the pasta and chickenBring a large pot of salted water to a boil and cook the spaghetti according to the package directions until al dente. While the pasta cooks, heat a large skillet over medium-high heat and add the diced chicken. Sauté the chicken until it is thoroughly cooked, ensuring it reaches an internal temperature of 165°F (74°C). Drain the spaghetti and set aside.Look for The chicken should be golden brown and cooked through.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Ensure the chicken is cut into uniform pieces for even cooking.
The chicken should be golden and fully cooked through. The pasta should be drained and ready to be incorporated. At this stage, the kitchen should smell savory and fresh, and the skillet should be clean enough to hold the sauce without any burnt bits clinging to the surface.
Emulsifying the sauce
- Create the creamy sauceIn the same skillet used for the chicken, reduce the heat to medium and pour in the heavy cream. Add the canned diced tomatoes with green chilies to the skillet. Stir the mixture continuously until the sauce begins to bubble and thicken slightly. Once the base is hot, slowly incorporate the shredded cheddar cheese, stirring constantly until the sauce is completely smooth and melted.Look for The sauce should look glossy and thick enough to coat the back of a spoon.Tip Add the cheese in small handfuls to prevent clumping.
The sauce should be bubbling and thick, with a uniform, orange-gold color from the melted cheese. It should look creamy and smooth, with no signs of oil separation. Check that the tomato bits are evenly distributed throughout the mixture before adding the pasta and chicken back into the skillet.
Final assembly
- Combine and finishReturn the cooked spaghetti and the seared chicken to the skillet with the cheese sauce. Using tongs, toss the ingredients together thoroughly until the spaghetti is evenly coated with the creamy mixture. Once combined and heated through, remove from the heat immediately. Garnish with chopped fresh parsley before serving while the dish is steaming hot and the cheese is perfectly melted and stringy.Look for The spaghetti should be fully coated in the thick, creamy sauce.Tip Toss gently to keep the spaghetti strands intact.
The spaghetti should be completely coated in the sauce, looking glossy and vibrant. The dish should be served immediately while the cheese is still stringy and the pasta is hot. Ensure the parsley garnish is applied just before serving to maintain its bright color and fresh appeal.
Common mistakes
Avoid overcooking the spaghetti, as it will lose its texture after being tossed in the sauce.
Another common mistake is adding the cheese while the sauce is at a rolling boil, which can cause the milk solids to separate; always lower the heat to medium or medium-low before incorporating the cheese.
Finally, do not overcrowd the skillet with the chicken, as this will cause it to steam rather than sear, leading to a loss of flavor development.
How to tell it’s done
The dish is considered done when the chicken has reached an internal temperature of 165°F (74°C) and the cheese sauce has thickened to a smooth, glossy consistency that coats the pasta evenly.
The spaghetti should be tender yet firm to the bite, and the overall mixture should be steaming hot throughout, indicating that the flavors have successfully melded together.
- Poultry: 165°F (74°C) in the thickest part
