Begin by bringing a large pot of salted water to a rolling boil. Carefully add the fettuccine pasta and cook according to the package instructions until it reaches an al dente texture. Once cooked, drain the pasta and set it aside.
While the pasta is cooking, take the chicken breasts and coat both sides generously with Cajun seasoning. Gently press the seasoning into the meat to ensure it adheres well for maximum flavor.
In a large skillet, heat the olive oil over medium-high heat. Once the oil is hot, place the seasoned chicken breasts in the skillet. Cook for about 5-7 minutes on each side, or until the chicken is juicy, cooked through, and has a lovely golden-brown color. Once cooked, transfer the chicken to a plate and let it rest for a few minutes before slicing it into strips.
Using the same skillet, add the sliced bell pepper and onion. Sauté for about 3-4 minutes until they start to soften. Next, add the minced garlic and cook for an additional minute until the garlic becomes fragrant and golden.
Pour the heavy cream into the skillet, stirring well to combine with the sautéed vegetables. Add the halved cherry tomatoes to the mix and allow the sauce to simmer for about 5 minutes. This will help it thicken slightly and infuse the flavors together beautifully.
Once the sauce has thickened, add the cooked fettuccine back into the skillet. Toss gently to coat the pasta evenly with the creamy sauce. Gradually stir in the freshly grated Parmesan cheese until it melts and blends into the sauce.
Taste your dish and season with salt and pepper as needed. Arrange the sliced chicken over the pasta and sauce, allowing the flavors to meld.
Finish off your dish with a sprinkle of freshly chopped parsley to add a pop of color and freshness.
