Ingredients
Chicken
- 1½ pounds boneless skinless chicken breasts
- 1 tablespoon Cajun seasoning (or to taste, use homemade salt-free or store-bought)
- 1½ teaspoons kosher salt (or to taste, reduce or omit if Cajun seasoning contains salt)
- 2 tablespoons unsalted butter
Pasta
- 16 ounces fettuccine (or linguine or pasta of choice)
Sauce
- 2 tablespoons unsalted butter
- 8 cloves fresh garlic (minced)
- 1 cup chicken broth
- 1 cup heavy whipping cream
- 3 cups parmesan cheese (freshly grated, approx. 12 ounces)
- ½ to 1 tablespoon Cajun seasoning (or to taste)
- ¼ to ½ teaspoon kosher salt (or to taste)
- 1 cup reserved pasta water
- Handful of fresh parsley (minced, plus extra for garnish)
Instructions
- Prepare the Chicken: Preheat a large skillet over medium-high heat. Season the chicken breasts liberally with Cajun seasoning and kosher salt on all sides.
- Sear the Chicken: Add butter to the hot skillet. Place chicken breasts in the skillet and sear until each side is browned and the internal temperature reaches 165°F, about 5-6 minutes per side.
- Rest the Chicken: Remove the chicken from the skillet and set aside to rest for 5-10 minutes before slicing. Keep the pan drippings in the skillet for the sauce.
- Cook the Pasta: Bring a large pot of heavily salted water to a boil. Cook the fettuccine for 1-2 minutes less than the package directions until al dente. Reserve 1 cup of pasta water before draining the pasta.
- Start the Sauce: Reduce skillet heat to medium. Add butter and a splash of chicken broth to the skillet. Add minced garlic and cook, stirring frequently, until fragrant, about 1 minute.
- Deglaze the Pan: Pour remaining chicken broth into the skillet, scraping up the browned bits from the bottom for flavor.
- Add Cream: Lower heat to low and add heavy cream, stirring to combine well.
- Incorporate Cheese: Gradually add parmesan cheese in small handfuls, stirring continuously after each addition until the cheese fully melts into a smooth sauce. Keep the heat low to prevent clumping.
- Season the Sauce: Season the sauce with remaining Cajun seasoning and salt to taste.
- Toss Pasta and Sauce: Add the cooked pasta, a splash of reserved pasta water, and minced parsley to the skillet. Toss well to coat the noodles evenly, adding more pasta water as needed to reach desired sauce consistency.
- Assemble the Dish: Slice the rested chicken breasts and arrange the slices over the pasta.
- Garnish and Serve: Sprinkle extra parsley and parmesan cheese on top. Serve immediately while hot.
Notes
- For a lower sodium dish, reduce or omit added kosher salt if using salted Cajun seasoning.
- Reserve pasta water is key to achieving creamy sauce consistency without thinning the flavor.
- Allowing the chicken to rest helps retain juices for tender, moist slices.
- Freshly grated parmesan melts best for smooth Alfredo sauce.
- Add Cajun seasoning gradually to control the spice level according to your preference.
