How to Make Cajun Shrimp and Steak Alfredo Pasta Recipe
Step 1: Cook the Pasta
Start by boiling your fettuccine until it’s perfectly al dente, just tender but with a little chew. This is crucial because it ensures the pasta holds up nicely when tossed with the rich Alfredo sauce later. Once cooked, drain it and set it aside for the next steps.
Step 2: Season the Steak and Shrimp
While the pasta cooks, generously coat the thinly sliced steak and shrimp with half the Cajun seasoning. This early seasoning locks in vibrant layers of smoky, spicy flavor, building the dish’s foundation right from the protein.
Step 3: Sear the Steak
Heat olive oil in a large skillet on medium-high heat. Add the steak slices and sear them for 2 to 3 minutes on each side until they develop a beautiful brown crust and reach your preferred doneness. Then, transfer the steak to a plate and let it rest; this keeps the meat juicy and tender.
Step 4: Cook the Shrimp
In the same skillet, cook the shrimp for 2 to 3 minutes until they turn pink and opaque. Using the same pan infuses the shrimp with the leftover flavor from the steak, elevating the overall taste. Remove the shrimp and set aside with the steak.
Step 5: Prepare the Alfredo Sauce
Reduce the skillet heat to medium and melt the butter. Add the minced garlic, sautéing until fragrant but not browned, about 1 minute. Pour in the heavy cream and bring it to a gentle simmer. Stir in Parmesan cheese, the remaining Cajun seasoning, black pepper, and salt if desired. Allow the sauce to thicken slightly, becoming luxuriously creamy.
Step 6: Combine Pasta, Steak, and Shrimp
Add the cooked fettuccine to the skillet and toss it thoroughly to coat every strand with the rich sauce. Return the steak and shrimp to the pan, mixing gently to combine and heat everything through so that the flavors meld in harmony.
How to Serve Cajun Shrimp and Steak Alfredo Pasta Recipe

Garnishes
A sprinkle of freshly chopped parsley brightens the plate with herbal freshness and vibrant green color, making the dish look as delightful as it tastes. If you want to amp up the heat, a pinch of red pepper flakes on top adds a nice visual and a spicy kick that complements the Cajun flavors perfectly.
Side Dishes
This hearty pasta stands well on its own, but pairing it with a crisp green salad or roasted vegetables provides a satisfying textural contrast. Garlic bread or a crusty baguette also makes a great addition to soak up any leftover sauce, making every last bite count.
Creative Ways to Present
For a dinner party, serve this creamy, spicy meal in individual shallow bowls so guests can enjoy the aromatic steam as they dig in. Drizzle a little extra Parmesan or a swirl of olive oil on top for a polished restaurant-quality touch. A wedge of lemon on the side can be a welcome addition to brighten the flavors.
Make Ahead and Storage
Storing Leftovers
Any leftovers from this Cajun Shrimp and Steak Alfredo Pasta Recipe should be cooled to room temperature then stored in an airtight container in the refrigerator. It will stay fresh and flavorful for up to 3 days, making it a convenient option for next-day meals.
Freezing
Although Alfredo sauce can sometimes separate when frozen, this dish can still be frozen if necessary. Cool completely, portion it into freezer-safe containers, and freeze for up to 2 months. Thaw overnight in the fridge before reheating gently on the stovetop or in the microwave, stirring frequently to bring back its creamy texture.
Reheating
To reheat leftovers without drying out the proteins or curdling the sauce, warm the pasta slowly over low heat, adding a splash of milk or cream if needed to loosen the sauce. Stir gently until heated through, and avoid overheating to keep everything tender and delicious.
