Tender chicken and a luscious sauce with a kick—this Cajun chicken Alfredo has it all. A few ingredients and half an hour is all you need to make dinner.
Cook pasta (16 ounces) according to package directions. Drain pasta, reserving 1 cup of pasta water, and dry the pasta pot. Set aside reserved pasta water.
Meanwhile, in a large bowl toss the cubed chicken (1 pound) with 1 teaspoon of Cajun seasoning until evenly coated.
In a large skillet, heat 1 tablespoon of the olive oil over medium-high heat until it begins to shimmer. Add the chicken in a single layer and cook without stirring, until one side is browned on each side and cooked through, about 5 minutes. Remove the chicken to a plate and set aside. Remove any oil from the pan.
Melt butter (2 tablespoons) in the skillet then saute onion (1 cup) and garlic (1 tablespoon) over medium-low heat until soft, about 5-7 minutes. Sprinkle flour (2 tablespoons) over vegetables and cook, stirring constantly for 1 minute.
Remove pan from heat and slowly whisk in cream (2 cups) and (1 can) Rotel until smooth.
Return skillet to medium and bring to a boil, stirring constantly. Reduce heat to low and stir cream cheese (4 ounces), parmesan (1 cup), and Cajun seasoning (1 1/2 teaspoon), and simmer gently until the cheese has melted.
Add pasta and chicken to the sauce and toss until evenly coated. Thin out sauce, as needed, adding reserved pasta water, a little at a time (you likely won't use the whole 1 cup). Taste and adjust salt and pepper to your liking. Garnish with parsley (2 tablespoons) and serve.
Notes
Reserved Pasta Water: The starch in the pasta water helps thicken the sauce and it also helps the sauce cling to the pasta.
Pasta Shape: If you want a different pasta shape, feel free to switch out the ziti! I love this sauce with fettuccine, bow tie, or rigatoni. Just use good Italian pasta.
Turn Up The Heat: If you want to spice this up, I suggest you add cayenne pepper or your favorite hot sauce.
