This Cajun Chicken and Shrimp Alfredo brings restaurant-quality comfort food to your own kitchen in just 30 minutes. Juicy chicken and tender shrimp meet a rich, garlicky parmesan cream sauce tossed with fettuccine — it’s indulgent enough for a special occasion but simple enough to pull off on a Tuesday night when you want something a little extra.
This is the dish my sister requests every single time she visits, without fail. The first time I made it for her, she asked for the recipe before she’d even finished her plate, then admitted she’d been ordering a version of it at a chain restaurant for years without realizing how easy it was to make at home. Now when she’s coming into town, I don’t even ask what she wants for dinner anymore — I just start pulling out the skillet.

- One skillet for the sauce: Keeps cleanup simple after a rich, flavorful meal.
Ingredient Notes
This recipe uses straightforward ingredients, but a few details matter for the best result:
- Fettuccine: The classic choice for alfredo since its width holds the creamy sauce well, though any pasta shape works if that’s what you have on hand.
- Chicken: Both chicken breast and thighs work well here — thighs will give you a slightly juicier bite, while breast keeps things leaner.
- Shrimp: Peeled and deveined, with tails off for easier eating. Cook just until they turn pink and curl, since overcooked shrimp can turn rubbery quickly.
- Heavy cream: This builds the rich base of the sauce — warm it gently and avoid letting it boil, which can cause it to separate.
- Parmesan cheese: Freshly grated parmesan melts much more smoothly into the sauce than pre-shredded varieties, which often contain anti-caking agents.
Step-by-Step Instructions
Preparation
- Cook the pasta. Bring a large pot of salted water to a boil and cook the fettuccine until just tender. Before draining, reserve about 1 cup of the pasta water to use later for adjusting the sauce.
- Cook the chicken. In a large skillet, heat 1 tablespoon of butter with the olive oil over medium heat. Add the chicken, season with salt and pepper, and cook until browned and cooked through, about 6 to 8 minutes. Move the chicken to a plate.
- Cook the shrimp. In the same skillet, add another tablespoon of butter. Add the shrimp, season with a pinch of salt and pepper, and cook for 1 to 2 minutes per side until they turn pink. Remove the shrimp and place them on the plate with the chicken.
Sauce
- Build the base. Lower the heat and add the last tablespoon of butter to the skillet. Add the minced garlic and stir for about 30 seconds until fragrant.
- Add the cream. Pour in the heavy cream and warm it gently for 2 to 3 minutes, making sure it doesn’t come to a boil.
- Melt in the cheese. Gradually stir in the parmesan cheese until it melts into a smooth sauce. If the sauce feels too thick, add a splash of the reserved pasta water and stir until it loosens.
Combine
- Bring it all together. Add the cooked pasta to the sauce and toss until evenly coated. Return the chicken and shrimp to the skillet and stir gently to combine everything.
- Finish and serve. Season with additional salt and pepper to taste, then top with extra parmesan and fresh herbs if desired.
Tips & Tricks
- Don’t boil the cream. Keeping the heat gentle when adding the heavy cream helps prevent the sauce from breaking or becoming grainy.
- Use freshly grated parmesan. It melts far more smoothly than pre-shredded cheese and gives the sauce a silkier texture.
- Save more pasta water than you think you’ll need. It’s the easiest way to loosen a sauce that’s turned out too thick.
- Cook the shrimp just until pink. Shrimp cook quickly, and pulling them off the heat as soon as they curl keeps them tender instead of rubbery.
Variations & Substitutions
- Add Cajun heat: Stir in a pinch of Cajun seasoning or paprika with the chicken and shrimp for a bolder, spicier flavor.
- Lighter version: Swap half-and-half for heavy cream, though the sauce will be noticeably thinner.
- Different pasta: Penne, linguine, or any pasta shape you have on hand works well in place of fettuccine.
- Herb finish: Top with chopped parsley or basil for a fresh contrast to the rich, creamy sauce.
Serving Suggestions
This dish is rich enough to be the main event, but a simple side rounds out the meal nicely. Serve with garlic bread to soak up the extra sauce, or pair it with a crisp green salad dressed in a light vinaigrette to balance the richness. A glass of white wine complements the creamy sauce beautifully.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, adding a splash of milk or reserved pasta water to loosen the sauce. Cream-based sauces can separate in the microwave, so stovetop reheating gives the best texture.

Frequently Asked Questions
Can I use only chicken or only shrimp instead of both?
Yes, feel free to use just one protein if you prefer. Simply double the amount of whichever one you’re using to keep the portions consistent.
Why did my sauce turn grainy?
This usually happens when the cream is boiled or the cheese is added too quickly over high heat. Keep the heat low and stir the parmesan in gradually for a smooth sauce.
Can I make this dish ahead of time?
The sauce is best made fresh, since cream sauces can thicken significantly once chilled. If needed, you can cook the chicken and shrimp ahead and store them separately, then make the sauce and pasta fresh when ready to serve.
What can I substitute for heavy cream?
Half-and-half can be used for a lighter sauce, though it will be thinner and less rich than the classic version made with heavy cream.
How spicy is this dish?
As written, this recipe is mild. If you want authentic Cajun heat, add Cajun seasoning or paprika to taste when cooking the chicken and shrimp.
