Ingredients
Cajun Chicken Alfredo Pasta
- 1.25 lbs boneless skinless chicken breast, sliced into cutlets
- 2 tbsp cajun seasoning, divided
- 2 tbsp olive oil
- 12 oz fettuccine
- 3 tbsp unsalted butter
- 4 cloves garlic, minced
- 1.5 cups heavy cream
- 1 cup freshly grated parmesan, plus more for serving
- 1 tsp smoked paprika
- 0.5 tsp kosher salt
- 0.25 tsp black pepper
- 2 tbsp fresh parsley, chopped, for garnish
How to Make Cajun Chicken Alfredo Pasta
- **Boil.** Bring a large pot of salted water to a boil. Cook fettuccine 1 minute under package time, then reserve 1 cup pasta water and drain.
- **Season.** Pat chicken dry and rub with 1.5 tbsp cajun seasoning, salt, and pepper. Heat olive oil in a 12 inch skillet over medium high heat.
- **Sear.** Cook chicken 4 to 5 minutes per side until deeply golden and 165F inside. Transfer to a plate and rest 5 minutes.
- **Build.** Reduce heat to medium. Melt butter in the same pan and add garlic. Cook 30 seconds until fragrant.
- **Cream.** Pour in heavy cream and remaining cajun seasoning plus smoked paprika. Simmer 2 minutes to thicken slightly.
- **Toss.** Off heat whisk in parmesan until smooth. Add cooked pasta and toss, splashing in pasta water as needed for a silky sauce.
- **Serve.** Slice chicken and lay over the pasta. Garnish with parsley and extra parmesan.
Why This Recipe Works
Cajun seasoning carries three flavor jobs at once. Paprika brings sweet smoke, cayenne carries heat, and garlic powder layers in savory depth. When you sear the chicken in a hot pan, those spices toast and bloom, which is the secret to a sauce that tastes restaurant deep in 30 minutes.
Deglazing the pan after the chicken comes out is what saves the alfredo from being flat. Heavy cream lifts the browned bits off the bottom, and those bits dissolve into the sauce as little flavor bombs. Skip this step and the sauce tastes thin.
Fresh grated parmesan melts smoothly because nothing is coating it. Pre-shredded cheese is rolled in cellulose so it does not clump in the bag, but that same coating stops it from emulsifying. Buy a wedge and grate it yourself for a sauce that hugs every noodle. For more ideas, see our High Protein Turkey Chili.
Tips
- Pat the chicken dry before seasoning so the cajun spices stick instead of sliding off.
- Use heavy cream not half and half. Half and half can split when it hits a hot pan.
- Reserve 1 cup pasta water before draining. A splash loosens the sauce if it tightens.
- Store leftovers in an airtight container in the fridge up to 3 days.
- Reheat on the stovetop with a splash of milk over low heat to bring the sauce back.
- Common mistake: do not skip resting the chicken 5 minutes before slicing or the juices run out.
Variations
- Swap chicken for shrimp and cook 2 to 3 minutes per side.
- Add 2 cups baby spinach in the last minute for a green boost.
- Use sun dried tomatoes for a tuscan twist on the cajun base.
- Stir in 1 cup cherry tomatoes halved with the cream for color.
- Swap fettuccine for penne or rigatoni for a sturdier bite.
- Add a pinch of red pepper flakes if you want extra heat.

Common Mistakes to Avoid
- Crowding the pan with chicken: Sear in 2 batches so the chicken browns instead of steams.
- Adding cold cream to a roaring pan: Pull the pan off the heat for 30 seconds first so the cream does not split.
- Using pre-shredded parmesan: Grate from a block. The anti caking coating prevents a smooth sauce.
- Skipping the pasta water: The starchy water is what makes the sauce cling to noodles.
