Start by bringing a large pot of salted water to a rolling boil. Once boiling, add the fettuccine pasta and cook according to package instructions until it reaches an al dente texture, typically around 8-10 minutes. Once done, drain the pasta and set it aside, making sure not to rinse it.
In a large skillet, melt the unsalted butter over medium heat. Once melted, add the minced garlic and sauté for about 1 minute, stirring continuously, until the garlic becomes fragrant and lightly golden.
Carefully pour in the heavy cream while stirring gently to incorporate it with the butter and garlic mixture. Allow this to simmer for about 2-3 minutes, letting it thicken slightly.
Gradually whisk in the freshly grated Parmesan cheese, stirring consistently until the sauce becomes smooth and creamy. Once incorporated, add the onion powder and freshly ground black pepper to flavor the sauce. Mix well to ensure even seasoning.
Add the shredded cooked chicken into the skillet along with the buffalo sauce. Stir everything together, ensuring the chicken is fully coated in the rich sauce. Allow it to heat through for another 2-3 minutes.
Gently add the cooked fettuccine pasta to the skillet, tossing everything together until the pasta is thoroughly coated in the buffalo Alfredo sauce.
Take a moment to taste the pasta; feel free to adjust the seasoning as needed or add extra buffalo sauce for a spicier kick.
Using pasta bowls, divide the creamy buffalo chicken pasta into portions. Garnish generously with freshly chopped parsley and, if desired, sprinkle crumbled blue cheese on top.
Notes
Adjust the buffalo sauce to your spice preference. Crumbled blue cheese is optional but adds great flavor.
