What You’ll Need

For the Cajun Chicken:

1 lb chicken breasts, thinly sliced or pounded to even thickness
1 tablespoon Cajun seasoning
1/2 teaspoon paprika
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/4 teaspoon black pepper
1/4 teaspoon salt (adjust depending on the seasoning mix)
1 tablespoon olive oil
1 tablespoon butter

For the Alfredo Sauce:

3 tablespoons butter
4 cloves garlic, minced
1 1/2 cups heavy cream
1 cup freshly grated Parmesan cheese
1/2 teaspoon Cajun seasoning (or more to taste)
Salt and pepper, to taste

For the Pasta:

12 ounces fettuccine
Salt for boiling water

For Garnish:

Fresh parsley
Extra Parmesan

Step-by-Step Instructions

Step 1: Prepare the Chicken

Pat the chicken dry with paper towels and place in a bowl.
Season with Cajun seasoning, paprika, garlic powder, onion powder, pepper, and salt. Toss to coat evenly.

Heat olive oil and butter in a large skillet over medium-high heat.
Once the butter begins to sizzle, add the seasoned chicken.

Cook for 4–6 minutes per side, depending on thickness, until golden and cooked through.
Remove the chicken from the pan and let it rest. Slice into strips once slightly cooled.

Step 2: Cook the Pasta

Bring a large pot of salted water to a boil.
Add fettuccine and cook according to package directions until al dente.

Reserve 1/2 cup of pasta water, then drain the noodles and set aside.

Step 3: Make the Alfredo Sauce

In the same skillet used for the chicken, lower the heat to medium. Add butter and let it melt.

Stir in minced garlic and cook for about 30 seconds until fragrant but not browned.

Pour in the heavy cream, stirring constantly. Let the mixture warm until it begins to gently simmer.

Add the grated Parmesan cheese gradually, whisking until completely melted and the sauce becomes thick and smooth.

Season with Cajun seasoning, salt, and pepper.
Adjust the seasoning to your preferred spice level.

If the sauce becomes too thick, add a splash of pasta water to loosen it.

Step 4: Combine Everything

Add the cooked fettuccine directly into the Alfredo sauce.
Use tongs to toss and coat the noodles evenly.

Add sliced Cajun chicken on top, allowing the sauce to cling to the seasoned edges.

Let everything warm together for 1–2 minutes.

Step 5: Serve

Transfer the pasta to plates or a serving dish.
Garnish with fresh parsley and extra Parmesan.
Serve warm while the sauce is silky and the chicken is juicy.

Tips for the Best Cajun Chicken Fettuccine Alfredo

Use freshly grated Parmesan
Pre-grated cheese doesn’t melt smoothly and can make the sauce grainy.
Avoid overheating the cream
Keep the sauce at a gentle simmer to prevent separation.
Season the chicken generously
The Cajun spice is what gives this dish personality — don’t be shy.
Cook pasta just until al dente
It will continue to soften slightly once mixed with the hot sauce.
Don’t rinse the pasta
The starch helps the Alfredo sauce cling perfectly to the noodles.
Use a heavy skillet
Cast iron or stainless steel works best for browning the chicken properly.

Flavor Variations

This dish is versatile and easy to customize. Here are some ideas:

Protein Variations

Shrimp Cajun Alfredo:
Swap the chicken for shrimp. Cook shrimp for 2–3 minutes per side until pink.

Cajun Sausage Alfredo:
Brown sliced andouille sausage for a smoky flavor boost.

Blackened Chicken Alfredo:
Use a heavy cast-iron skillet to get a darker, crispier crust on the chicken.

Sauce Variations

Creamier Alfredo:
Add an extra 1/4 cup Parmesan or an additional splash of cream.

Spicier Alfredo:
Increase the Cajun seasoning or add a pinch of cayenne.

Tomato Cajun Alfredo:
Add 1/2 cup tomato sauce or crushed tomatoes for a creamy Cajun rosé sauce.

Serving Suggestions

Pair your Cajun Chicken Alfredo with:

Garlic bread
A simple green salad
Roasted vegetables
Steamed broccoli
Sauteed spinach
Grilled asparagus

For a full meal, serve with a refreshing side that balances the richness of the Alfredo.

How to Store and Reheat

Storing:

Transfer leftovers to an airtight container.
Store in the refrigerator for up to 3 days.

Reheating:

Reheat gently on the stove over low heat.
Add a splash of cream, milk, or broth to bring the sauce back to life.
You can also microwave in short intervals, stirring to prevent drying.

Freezing:

Cream-based sauces do not freeze well, so freezing is not recommended for this recipe.

Make-Ahead Tips

Cook the chicken ahead of time and store it in the refrigerator.
Pre-grate the Parmesan to speed up preparation.
The Alfredo sauce is best made fresh, but you can prepare ingredients in advance for a smoother process.

Troubleshooting Guide

Sauce too thin:
Add more Parmesan or simmer for a few minutes longer.

Sauce too thick:
Add reserved pasta water or more cream.

Chicken not browning:
Increase the heat slightly and avoid overcrowding the pan.

Cheese clumping:
Add it slowly and whisk continuously at low heat.

Too spicy:
Add extra cream or cheese to balance the heat.

Frequently Asked Questions

Can I use milk instead of cream?
Heavy cream produces the best texture. Milk will result in a thinner, less creamy sauce.

Can I use pre-cooked chicken?
Yes, but season it well and warm it in the pan before adding to the pasta.

Can I use linguine instead of fettuccine?
Absolutely — any long pasta works well with Alfredo sauce.

Is Cajun seasoning very spicy?
Most blends are moderately spicy. You can adjust the quantity to suit your taste.

Can I double this recipe?
Yes — simply scale all ingredients evenly. Use a larger skillet for the sauce.
