Cajun Chicken and Shrimp Alfredo

The Creamy, Spicy Pasta Dinner Your Weeknight Needs

If you have ever ordered Cajun Chicken and Shrimp Alfredo at a restaurant and thought, "I need to learn how to make this at home," this recipe was written for you. We are talking silky, restaurant-quality Alfredo sauce clinging to perfectly cooked fettuccine, loaded with boldly seasoned chicken strips and juicy, pink shrimp that have just the right amount of Cajun kick. It is one of those dinners that feels genuinely special without requiring a culinary degree or three hours in the kitchen.

This is the kind of Cajun Shrimp Pasta Alfredo recipe that earns a spot in your permanent dinner rotation. It works for a weeknight family meal, a date night at home, and even an impressive dinner party dish that tastes like it came from a steakhouse kitchen.

Why This Recipe Works So Well

The secret here is layering flavor at every step. The chicken and shrimp are seasoned separately and cooked in the same pan, which means every bit of that Cajun-spiced fond gets deglazed right into your Alfredo sauce. Nothing is wasted.

The sauce itself hits that sweet spot between rich and light. Heavy cream forms the base, freshly grated Parmesan adds savory depth, and a small amount of cream cheese gives the sauce an extra silky body that clings to every strand of pasta. It is the kind of creamy chicken and shrimp Alfredo that coats the back of a spoon and makes you want to eat more than you planned.

A few things that make this version stand out:

• Fresh Parmesan is non-negotiable. Pre-shredded cheese contains anti-caking agents that turn your sauce grainy. Grate it yourself and you will immediately notice the difference.
• Cook the protein in stages. Shrimp cook in under 3 minutes. Combining them with chicken in the same pan at the same time is how you end up with either raw chicken or rubber shrimp. Separate cooking = perfect results.
• Reserve that pasta water. It is liquid gold for adjusting sauce consistency at the end.

Before we get cooking, the right tools and quality ingredients genuinely make a difference here. A wide, heavy skillet ensures your chicken sears properly rather than steaming, and good-quality Cajun seasoning can elevate the whole dish with no extra effort:

Choosing Your Cajun Seasoning

You can absolutely use a store-bought Cajun blend like Tony Chachere's or Slap Ya Mama and get fantastic results. If you prefer to mix your own, combine paprika, garlic powder, onion powder, dried oregano, dried thyme, cayenne, black pepper, and salt. Homemade blends let you control the sodium and heat level, which is especially helpful if you are cooking shrimp recipes for kids or serving guests who prefer things on the milder side.

Chef's Tip: If your Cajun seasoning already contains salt, taste your sauce before adding any additional salt. Store-bought blends vary wildly in sodium content and it is much easier to add salt than to fix an over-salted Alfredo sauce.

What to Cook With Chicken Tenders

This recipe uses sliced chicken breasts, but chicken tenders are a fantastic swap, especially for family dinners. They cook slightly faster, they stay incredibly juicy, and kids tend to love them. If you have been wondering what to cook with chicken tenders beyond the usual breaded-and-fried versions, tossing them in Cajun seasoning and folding them into a creamy Alfredo sauce is one of the most satisfying answers you will find.

For the shrimp, go with large or extra-large raw shrimp rather than pre-cooked. Pre-cooked shrimp will turn rubbery by the time the sauce comes together. Fresh or thawed raw shrimp take only 90 seconds per side and absorb the Cajun seasoning so much better.

Making It a Family Meal

One of the best things about this Cajun Shrimp and Chicken Alfredo recipe is how easy it is to customize for different palates at the table. The creamy Alfredo sauce naturally tempers the heat of the Cajun spice, so even what sounds like a spicy dish often lands at a very approachable medium. For younger kids or heat-sensitive eaters, simply pull their portion of pasta and sauce before adding extra red pepper flakes, or reduce the Cajun seasoning slightly in the beginning.

Serve it with a simple green salad, garlic bread, or roasted broccoli and you have a complete, satisfying dinner that genuinely competes with anything on a restaurant menu.

• 12 oz fettuccine pasta, cooked al dente, reserve 0.5 cup pasta water
• 1 lb boneless skinless chicken breasts, sliced into thin strips or tenders
• 3/4 lb large raw shrimp, peeled and deveined, tails on or off
• 2 tbsp Cajun seasoning, divided, store-bought or homemade
• 2 tbsp olive oil, extra virgin
• 3 tbsp unsalted butter, divided
• 4 garlic cloves, minced
• 1 1/2 cups heavy cream, at room temperature
• 1 cup Parmesan cheese, freshly grated, not pre-shredded
• 2 oz cream cheese, softened, optional but adds extra creaminess
• 1/2 cup chicken broth, low sodium
• 1/2 tsp smoked paprika
• 1/2 tsp onion powder
• 1/2 tsp salt, adjust to taste
• 1/4 tsp black pepper, freshly cracked
• 2 tbsp fresh parsley, chopped, for garnish
• 1/4 tsp red pepper flakes, optional, for extra heat

Instruction

1

Bring a large pot of salted water to a boil. Cook the fettuccine according to package directions until al dente. Before draining, reserve 0.5 cup of pasta water. Drain and set aside.

2

Pat the chicken strips dry with paper towels. Season generously with 1 tablespoon of Cajun seasoning, the smoked paprika, onion powder, salt, and black pepper. Toss the shrimp with the remaining 1 tablespoon of Cajun seasoning.

3

Heat 1 tablespoon of olive oil and 1 tablespoon of butter in a large skillet or cast iron pan over medium-high heat. Add the chicken strips in a single layer. Cook for 4 to 5 minutes per side until golden and cooked through to an internal temperature of 165 degrees F (74 degrees C). Transfer to a plate and tent with foil.

4

In the same skillet, add the remaining 1 tablespoon of olive oil. Add the seasoned shrimp in a single layer and cook for 1 to 2 minutes per side until pink and just curled. Do not overcook. Transfer to the plate with the chicken.

5

Reduce heat to medium. Add the remaining 2 tablespoons of butter to the skillet. Once melted, add the minced garlic and cook for 30 to 60 seconds, stirring constantly, until fragrant.

6

Pour in the chicken broth and scrape up any browned bits from the bottom of the pan. Let it reduce for about 1 minute.

7

Reduce the heat to medium-low. Pour in the heavy cream and add the softened cream cheese if using. Stir continuously until the cream cheese is fully melted and the sauce is smooth.

8

Add the freshly grated Parmesan cheese a small handful at a time, stirring well between each addition to prevent clumping. Simmer gently for 3 to 4 minutes until the sauce thickens. If the sauce becomes too thick, stir in a splash of the reserved pasta water.

9

Add the drained fettuccine to the sauce and toss with tongs until every strand is coated. Taste and adjust seasoning with salt, pepper, or more Cajun seasoning as needed.

10

Return the cooked chicken and shrimp to the pan and nestle them into the pasta. Heat for 1 to 2 minutes until everything is warmed through.

11

Serve immediately, garnished with chopped fresh parsley, extra grated Parmesan, and red pepper flakes if desired.

Equipment

• Large pot for boiling pasta
• Large skillet or cast iron pan (12-inch recommended)
• Tongs
• Box grater or Microplane for Parmesan
• Measuring cups and spoons
• Cutting board and sharp knife
• Ladle or wooden spoon

Notes

For the creamiest Alfredo sauce, always grate your Parmesan fresh from a block. Pre-shredded cheese contains anti-caking agents that make the sauce grainy. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat with a splash of cream or broth to loosen the sauce. Do not microwave shrimp on high heat or it will turn rubbery. This dish does not freeze well due to the cream sauce. For a lighter version, substitute half-and-half for the heavy cream, though the sauce will be thinner.

Serving, Storing, and Variations

To serve: Plate the pasta immediately and finish each bowl with a generous handful of fresh Parmesan, chopped parsley, and red pepper flakes for color and a little extra heat. Warm bowls help the sauce stay looser and more beautiful longer.

Leftovers: Store in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of cream or chicken broth to revive the sauce. Skip the microwave for the shrimp.

Variations worth trying:

• All shrimp, no chicken: Double the shrimp and skip the chicken for a lighter shrimp Alfredo that comes together in about 20 minutes total.
• Add vegetables: Sauteed bell peppers, baby spinach, or sun-dried tomatoes fold beautifully into the sauce.
• Swap the pasta: Penne or rigatoni catch the sauce in their ridges and tubes in a completely different and equally delicious way.
• Go lower carb: Serve the Cajun chicken and shrimp Alfredo sauce over zucchini noodles or spaghetti squash for a satisfying lighter version.
