Start by slicing the chicken breasts into even strips so they cook uniformly. I season them generously with Southwest seasoning, salt, and pepper, making sure every piece is coated. This step is key because the chicken sets the flavor foundation for the entire dish.
Heat olive oil in a large skillet over medium heat and add the seasoned chicken. I cook it for a few minutes on each side until it’s golden and fully cooked through. Once done, I remove the chicken from the skillet and set it aside so it stays juicy.
In the same skillet, I melt butter and add minced garlic, letting it cook just until fragrant. Then I slowly pour in the heavy cream, stirring constantly to keep it smooth. The sauce begins to thicken gently as it warms.
I reduce the heat slightly before adding the freshly grated Parmesan cheese. Stirring continuously helps the cheese melt evenly without clumping. The sauce should now be creamy, rich, and smooth.
Next, I add the cooked pasta directly into the sauce, tossing it gently to coat every piece. Then I return the chicken to the skillet, mixing everything together so the flavors blend beautifully.
I taste the pasta and adjust salt and pepper as needed. Letting the dish rest for a minute or two before serving helps the sauce cling better to the pasta and chicken.
