Kitchen Tools You’ll Need
- Large pot
- Deep skillet
- Mixing spoon
- Plate for cooked ingredients
- Measuring cups and spoons
Ingredients
- 8 ounces uncooked fettuccine
- 2 chicken breasts cut into 1″ pieces
- 1/2 pound shrimp (I used 31/40 size) thawed & peeled
- 1/2 teaspoon garlic powder
- 1/2 tablespoon + 1/2 tablespoon Cajun seasoning (use a low or no salt variety)
- 2 tablespoons olive oil
- 2 tablespoons butter
- 1 cup heavy/whipping cream
- 4 ounces cream cheese (I used 1/2 block of Philly)
- 2 cloves garlic minced
- 1 cup freshly grated parmesan cheese
- Salt & pepper to taste

How to Make Cajun Chicken and Shrimp Alfredo
Step 1. First, take the cream cheese out of the refrigerator about 30 minutes before you start cooking. If you’re short on time, a quick 20-30 second microwave session will soften it. This helps it incorporate more smoothly into your sauce later on.
Step 2. Bring a large pot of salted water to a boil. It’s important to season your pasta water so the fettuccine has flavor from the start. Cook the pasta according to the package instructions until it reaches an al dente texture, which should have a slight bite to it.
Step 3. If your shrimp are frozen, make sure to thaw them under cool running water. Afterward, if you prefer, you can leave the tails on for presentation. Once thawed, pat the shrimp dry with a paper towel. Meanwhile, cut your chicken breasts into 1-inch pieces and season both the shrimp and chicken with garlic powder and half a tablespoon of Cajun seasoning.
Step 4. Heat olive oil in a deep skillet over medium-high heat until it shimmers. Carefully add the seasoned shrimp and cook for about three minutes, flipping them once. You want them pink and opaque – when they look like that, transfer them to a plate and set aside.
Step 5. Add the chicken pieces to the same skillet and cook them for 5-6 minutes. Stir occasionally and allow them to brown a little for flavor. Once the chicken is fully cooked, transfer it to the plate with the shrimp.
Step 6. Remove the skillet from the heat. Add butter, heavy cream, cream cheese, the remaining Cajun seasoning, and minced garlic. Return the skillet to the stove, reducing the heat to medium. Stir the mixture gently for a couple of minutes until the cream cheese seamlessly melds into the sauce.
Step 7. Allow the sauce to bubble gently for about 2-3 minutes. You’re looking for a slightly thickened consistency, which will happen as it simmers. Keep an eye on it to make sure it’s not boiling too vigorously.
Step 8. Incorporate the freshly grated parmesan cheese into the sauce, stirring until it’s melted and well blended. Then, bring back the cooked shrimp and chicken to the pan, warming everything through for a few minutes while mixing gently.
Step 9. For an optional step that I find enhances the sauce’s richness, add a splash of hot pasta water from your pot just before you drain the fettuccine. This will help to thin the sauce to your desired consistency. Toss the drained pasta with the sauce immediately to coat.
Step 10. Serve your Cajun Chicken and Shrimp Alfredo hot. A little extra parmesan on top and some chopped parsley can elevate the presentation. A squeeze of fresh lemon juice adds a nice brightness, too!

Serving Suggestions
This Cajun Chicken and Shrimp Alfredo is a versatile dish that can shine in various situations. It makes for a satisfying family meal that everyone will enjoy around the dinner table. Leftovers can be excellent for lunch, either heated or cold. It’s also a great dish for casual gatherings; serve it alongside a fresh salad or crusty bread to soak up all that delicious sauce.
Pro Tips for Best Results
- Ensure your cream cheese is softened for easier blending into the sauce.
- Use low-sodium Cajun seasoning if you prefer a milder flavor.
- Adjust the thickness of the sauce with pasta water to suit your taste.
- Don’t overcook the shrimp; they should be just cooked through for the best texture.
- Stir the pasta into the sauce while it’s warm to help it absorb the flavors.
Common Mistakes to Avoid
- Not seasoning the pasta water: Failing to salt the water can lead to bland pasta. Always season the boiling water to enhance the overall flavor of the dish.
- Overcooking the shrimp: Shrimp cook quickly and can become rubbery if overcooked. Look for them to become pink and opaque, which indicates they’re done.
- Skip the resting time for cream cheese: If you forget to soften the cream cheese, it may sit in chunks in the sauce. Either let it sit beforehand or microwave it briefly to soften.
- Rushing the sauce: Allow the sauce to simmer gently for the best consistency. Skipping this step can lead to a watery sauce instead of a creamy one.
- Not adjusting seasoning: Tasting the sauce before serving is crucial. Adjust with salt and pepper to ensure balanced flavor.
- Not saving pasta water: This starchy water helps thicken and enrich the sauce. Always save a bit before draining the pasta.
Variations & Substitutions
If you want to change things up a bit, consider adding vegetables such as spinach or bell peppers for extra nutrition and flavor. You could also use penne or rigatoni instead of fettuccine, depending on your preference. For a spicier kick, feel free to add a pinch of cayenne pepper while preparing the sauce.
Storage & Reheating
Once cooled, store leftovers at room temperature for a couple of hours max; then refrigerate. In the fridge, the dish will last up to 3 days. If you plan to freeze it, do so as soon as possible after cooking, and it will hold well for about a month. To reheat, gently warm in the microwave, adding a splash of milk or cream to restore the sauce’s creamy texture.
Frequently Asked Questions
Can I make this recipe ahead of time?
Yes, you can prepare the chicken and shrimp ahead and store them in the fridge. However, it’s best to cook the fettuccine and mix everything just before serving to maintain the sauce’s creaminess.
How long does it last in the fridge?
When properly stored in an airtight container, the dish will last in the refrigerator for up to 3 days. Just be sure to reheat gently.
Can I freeze this recipe?
Freezing is possible, although the cream sauce may change texture upon thawing. If you freeze the dish, aim to consume it within a month for the best quality.
What can I substitute for one ingredient?
If you’re out of heavy cream, a mix of half-and-half and milk can be a workable alternative. Just know it may slightly alter the richness.
Why didn’t my recipe turn out as expected?
There could be several reasons, from not seasoning properly to incorrect cooking times for the shrimp. Every stovetop varies, so tasting and adjust along the way is essential to your preferred flavor.
