Ingredients

Chicken Breasts – Lean, tender, and perfect for soaking up all that Cajun flavor. You can also use chicken thighs for a juicier option.

Zestiny Cajun and Garlic Butter Seasoning – This is where the bold flavor comes from. Cajun seasoning adds spice and depth, while garlic butter seasoning gives it that rich, savory finish.

Oregano + Black Pepper – Adds extra seasoning layers and balances out the richness of the sauce.

Fettuccine Pasta – The classic choice for Alfredo, its wide shape holds onto the creamy sauce perfectly.

Garlic & Herb Butter – Adds a rich base and extra flavor to the sauce right from the start.

Minced Garlic – Fresh garlic enhances the overall flavor and gives the sauce that signature Alfredo taste.

Heavy Whipping Cream – Creates that smooth, creamy texture Alfredo is known for.

Parmesan Cheese – The key to a rich, salty, cheesy sauce. Freshly shredded works best for melting.

Mozzarella & Cream Cheese – Adds extra creaminess and helps make the sauce thick and stretchy.

How To Make Creamy Cajun Chicken Alfredo

1. Cook the Fettuccine Noodles

Bring a large pot of salted water to a boil and cook the fettuccine noodles according to package instructions. Drain and set aside.

2. Season the Chicken

Season both sides of the chicken breasts with Cajun seasoning, garlic butter seasoning, oregano, and black pepper. Drizzle lightly with olive oil and rub the seasoning into the chicken.

3. Cook the Chicken

Heat a skillet over medium-high heat with a little olive oil. Add the chicken and sear for about 5–7 minutes per side, or until fully cooked and golden on the outside. Remove from the pan and let it rest before slicing.

4. Saute the Herbs

In the same pan, melt the garlic & herb butter over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant.

5. Make the Cheese Sause

Pour in the heavy cream and stir well. Let it simmer gently for a few minutes, then add cream cheese, Parmesan cheese, mozzarella cheese, and Cajun seasoning. Stir until the sauce is smooth, creamy, and fully combined.

6. Add Pasta and Cut Chicken

Add the cooked pasta to the sauce and toss until evenly coated. Then slice the chicken and place it on top of the pasta or mix it in.

FAQ

Can I use pre-cooked or rotisserie chicken?

Yes! Just slice it and add it to the sauce at the end.

How do I keep the sauce from getting too thick?

Add a splash of reserved pasta water or a little more cream to loosen it up.

Can I make this ahead of time?

It’s best fresh, but you can make the sauce ahead and reheat gently.

What’s the best cheese to use?

Freshly grated Parmesan melts best and gives the best flavor.

How do I know when the chicken is done?

Internal temperature should reach 165°F and juices should run clear.

Storage and Reheating

How to Store

1. Refrigerator

Store in airtight containers for 2-3 days. Store chicken separately from the pasta/sauce to maintain texture. 

2. Freezer

While cream-based sauces can break, it can be frozen for up to 1-3 months, though not ideal.

Tips for Reheating

On the Stovetop:

• Reheat over low heat, stirring often, adding a splash of milk or heavy cream to restore the sauce’s consistency.

In the Microwave:

• Reheat in 30-45 second intervals, stirring in between to prevent the sauce from separating or burning.
