Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil. Add the penne or bow tie pasta and cook according to package instructions until al dente. Drain the pasta, reserving about ½ cup of the cooking water, and set it aside.
Step 2: Prepare the Chicken
While the pasta is cooking, season the chicken breasts with Cajun seasoning on both sides. In a large skillet, heat the olive oil over medium-high heat. Once hot, add the chicken breasts and cook for about 6-7 minutes on each side, or until they are cooked through and golden brown. Remove the chicken from the skillet and let it rest for a few minutes before slicing it into strips.
Step 3: Make the Sauce
In the same skillet, reduce the heat to medium and add the butter. Once melted, add the diced onion, cooking until it becomes translucent, about 3-4 minutes. Next, add the minced garlic and sauté for an additional minute until fragrant.
Step 4: Add Cream and Cheese
Pour in the heavy cream, stirring to combine with the onion and garlic. Bring the mixture to a gentle simmer. Stir in the lemon zest and freshly grated Parmesan cheese, mixing until the cheese has melted and the sauce is smooth. If the sauce is too thick, add a splash of the reserved pasta water to reach your desired consistency.
Step 5: Combine Everything
Add the cooked pasta and sliced chicken to the creamy sauce, tossing everything together until well coated. Season with kosher salt and freshly ground black pepper to taste. Let it cook for an additional minute to heat through.
Step 6: Garnish and Serve
Serve the pasta hot, garnishing with diced Roma tomatoes, chopped parsley, green onions, and a sprinkle of shredded Parmesan on top. Enjoy your homemade Spicy, Creamy, Delicious: Chilis Cajun Chicken Pasta!
