1. In a large pot, bring salted water to a boil. Add your choice of pasta and cook according to the package instructions, aiming for an al-dente texture. Don’t forget to reserve ½ cup of the pasta water before draining.
2. While the pasta cooks, season the chicken breast pieces with the fajita seasoning. This adds a wonderful layer of flavor right from the start.
3. Heat olive oil in a large heavy-duty skillet over medium to high heat. Once hot, add the seasoned chicken pieces to the pan. Cook them for about 2 to 3 minutes, or until they turn golden brown and are cooked through. You'll know they are ready when they are no longer pink in the center.
4. Add the sliced bell pepper, onion, and minced garlic to the skillet. Stir everything together and cook for an additional 2 to 3 minutes. Look for the onion to become tender and translucent, which indicates it’s ready.
5. Once the vegetables are tender, it’s time to bring in the star of the show: pour in the heavy cream along with the reserved pasta water. This will create a luscious sauce that coats everything beautifully. Bring the mixture to a gentle simmer.
6. Now, add in your cooked pasta and cheddar cheese. Stir everything together gently, ensuring the pasta is well coated with the creamy sauce. Keep simmering for about 5 minutes, allowing the cheese to melt fully and the flavors to meld.
7. Once everything is combined and heated through, it’s time to plate up! Sprinkle with fresh cilantro if desired for a pop of color and flavor.
8. Serve immediately and enjoy your Creamy Chicken Fajita Pasta with loved ones, savoring each delicious bite!
