Ingredients needed for this easy Cajun Chicken Alfredo Pasta

• 12 oz fettuccine noodles
• 1 lb boneless skinless chicken breast
• 2 Tbsp extra virgin olive oil
• 3 Tbsp Cajun seasoning, divided
• 3 Tbsp unsalted butter
• 2 cups heavy cream
• 1 cup shredded Parmesan cheese
• 1/2 tsp salt
• 1/2 tsp black pepper
• 1 diced tomato (optional)
• 1/4 cup chopped parsley (optional)

How to make the best Cajun Chicken Alfredo Pasta

• Bring a large pot of water to a boil and add 2 teaspoons salt. Cook the fettuccine until al dente, drain, and set aside.
• While the pasta cooks, season both sides of the chicken breasts with 2 tablespoons of Cajun seasoning.
• Heat the olive oil in a large skillet over medium heat. Sear the chicken about 4 minutes per side, or until it reaches an internal temperature of 165°F (74°C). Remove the chicken, tent with foil, and let it rest for a few minutes before slicing.
• In the same skillet, melt the butter over medium heat. Whisk in the heavy cream, salt, pepper, and the remaining 1 tablespoon of Cajun seasoning. Bring to a gentle simmer, whisking for 3–4 minutes until slightly reduced.
• Stir in the shredded Parmesan until the sauce thickens. If the sauce becomes too thick, loosen it with a splash more heavy cream or a tablespoon of reserved pasta water.
• Add the cooked fettuccine and toss to coat evenly in the sauce.
• Serve immediately topped with sliced Cajun chicken, diced tomatoes, chopped parsley, and extra Parmesan. Enjoy!

Tips for making the best Cajun Chicken Alfredo Pasta

• Pound or butterfly the chicken breasts for even, quick cooking.
• Rub the Cajun seasoning into the chicken so it forms a flavorful crust when seared.
• Make sure the oil is hot before adding the chicken to achieve a good sear.
• Let the chicken rest after cooking to keep it juicy.
• Cook pasta to al dente to avoid a mushy final dish.
• If the Alfredo sauce gets too thick, add heavy cream or a tablespoon of reserved pasta water at a time until you reach the desired consistency.

What kind of Parmesan cheese should I use?

Shredded Parmesan works best in homemade Alfredo because it melts smoothly and creates a creamy texture. Use pre-shredded Parmesan or grate a fresh block for the best flavor and texture.

Can I use different pasta noodles?

Yes. Fettuccine gives a classic Alfredo presentation, but any sturdy pasta—like linguine, pappardelle, or penne—will work. Avoid very thin pastas like angel hair, which can be overwhelmed by the rich sauce.
