What Kind of Pasta Works Best for Cajun Alfredo?

Fettuccine is the classic go-to, thanks to its wide surface area that soaks up that luscious Alfredo sauce like a champ. But you can get playful—penne, rigatoni, or even rotini all work great, depending on what’s in your pantry. The key is choosing a pasta that can hold onto the creamy sauce and deliver that flavor-packed bite every time.

Ingredients for the Creamy Cajun Alfredo Pasta with Garlic Butter Chicken Bites

Chicken Breasts – Tender and lean, chicken breasts soak up that garlic butter and Cajun seasoning beautifully.

Butter & Garlic – The foundation for the golden, flavorful sear on your chicken bites.

Cajun Seasoning – This is the star of the show. It brings the heat, the depth, and the classic Southern kick to the entire dish.

Heavy Cream – For a thick, rich Alfredo sauce that clings to every noodle.

Parmesan Cheese – Adds the salty, nutty flavor that turns the cream into a silky, cheesy dream.

Pasta – Fettuccine or any sauce-loving pasta is perfect for delivering those bold bites.

Olive Oil – Helps give your chicken a nice sear while keeping things juicy.

Salt & Pepper – To balance and round out all the other bold flavors.

Parsley (optional) – A little chopped parsley gives the final dish a pop of color and freshness.

How To Make the Creamy Cajun Alfredo Pasta with Garlic Butter Chicken Bites

Step 1: Prep and Season the Chicken

Start by cutting your chicken breasts into bite-sized cubes. Pat them dry with paper towels, then toss them with Cajun seasoning, salt, pepper, and a splash of olive oil. Let them marinate for at least 10 minutes while you prep the other ingredients.

Step 2: Sear the Chicken Bites in Garlic Butter

In a large skillet, melt butter and add minced garlic. Once fragrant, add the seasoned chicken in a single layer. Sear until golden brown and fully cooked through, about 4-6 minutes, turning occasionally for an even cook. Remove from the pan and set aside.

Step 3: Boil the Pasta

While the chicken cooks, bring a pot of salted water to a boil and cook your pasta until al dente. Reserve a bit of pasta water before draining to help loosen the sauce later if needed.

Step 4: Make the Cajun Alfredo Sauce

In the same skillet you used for the chicken (leave those flavorful brown bits!), pour in the heavy cream and bring to a gentle simmer. Whisk in more Cajun seasoning and slowly stir in the grated Parmesan cheese until smooth and creamy. Taste and adjust seasoning if needed.

Step 5: Combine Pasta and Sauce

Add the drained pasta directly into the skillet with the Alfredo sauce. Toss everything together gently, letting the noodles soak up the creamy Cajun goodness. If the sauce gets too thick, add a splash of reserved pasta water.

Step 6: Finish with Chicken and Serve

Add the garlic butter chicken bites back into the pan. Give everything one last toss or stir, ensuring it’s all evenly coated. Serve hot, garnished with parsley for a touch of color.

How to Serve and Store Creamy Cajun Alfredo Pasta

This pasta is best served hot and fresh right off the stove. The creamy Cajun Alfredo sauce clings perfectly when it’s freshly tossed, and the garlic butter chicken is juiciest just after searing. Plate it up with a side of crusty garlic bread or a light green salad to balance the richness.

For storing, transfer leftovers to an airtight container and refrigerate for up to 3 days. When reheating, add a splash of milk or cream to bring back the saucy texture. Avoid microwaving too long, as it can dry out the chicken. A gentle reheat on the stove is ideal.

Frequently Asked Questions

How spicy is the Cajun Alfredo sauce?

It has a noticeable kick, but it’s not overwhelmingly hot. You can always adjust the spice level by using more or less Cajun seasoning to suit your taste.

Can I use pre-cooked chicken?

Yes, though fresh chicken bites seared in garlic butter offer the best flavor. If using pre-cooked chicken, just warm it in the butter and garlic for a quick boost.

What if I don’t have heavy cream?

You can substitute with half-and-half or a mix of whole milk and a bit of cream cheese for thickness, though the result won’t be quite as rich.

Is this dish gluten-free?

Not as written, but you can make it gluten-free by using your favorite gluten-free pasta and ensuring your Cajun seasoning is gluten-free.

Can I make it vegetarian?

Absolutely. Swap the chicken for roasted veggies like mushrooms, zucchini, or bell peppers. Keep the same creamy Cajun sauce for that irresistible flavor.
