How to Make Cajun Shrimp and Steak Alfredo Pasta Recipe
Step 1: Season the Proteins with Cajun Spice
Begin by seasoning your peeled shrimp and thinly sliced sirloin steak evenly with the Cajun seasoning. This step is crucial as it infuses every bite with the signature smoky, spicy flavor that elevates this dish beyond ordinary Alfredo pasta. Be generous and make sure each piece is well coated to build that wonderful depth.
Step 2: Cook the Fettuccine
While the proteins absorb flavor, cook your fettuccine pasta according to the package instructions until it reaches that perfect al dente texture. Drain and set the pasta aside because the magic really happens when it meets the creamy sauce and seasoned proteins later.
Step 3: Sauté Shrimp to Perfection
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the Cajun-spiced shrimp and cook them until they turn a lovely pink and become opaque, which usually takes about 2 to 3 minutes per side. Once cooked, remove the shrimp and set them aside; they only need a short time on the heat so they stay juicy and tender.
Step 4: Cook the Steak Strips
In the same skillet, pour in the remaining tablespoon of olive oil, then add your seasoned steak strips. Sauté these beauties until they develop a rich brown crust and reach your preferred doneness—about 4 to 5 minutes for medium-rare. Removing the steak at the right time ensures it stays tender and juicy rather than overcooked.
Step 5: Sauté the Vegetables
Lower the heat to medium and introduce the minced garlic, along with the sliced red and green bell peppers and onions. Stir and cook them until the vegetables soften and release their natural sweetness, about 4 to 5 minutes. This colorful veggie medley brings freshness and slight crunch to balance the creamy sauce and protein.
Step 6: Prepare the Alfredo Sauce
Next, pour in the heavy cream, stirring gently to combine with the sautéed vegetables. Let the mixture come up to a gentle simmer, allowing the cream to thicken slightly as it mingles with the robust flavors from the skillet.
Step 7: Add Parmesan Cheese
Sprinkle the grated Parmesan into the creamy sauce and stir continuously until the cheese fully melts and the sauce turns luxuriously smooth and thick. This step is what transforms the dish into a rich Alfredo pasta that clings beautifully to every noodle and protein piece.
Step 8: Combine All Ingredients
Return your cooked Cajun-spiced shrimp and steak to the skillet, carefully folding them into the velvety sauce. Then add the drained fettuccine pasta, tossing everything together so every strand is coated with that flavorful, creamy goodness. Adjust seasoning with extra salt, pepper, or a sprinkle of Cajun seasoning to taste at this stage.
Step 9: Garnish and Serve
Finally, sprinkle freshly chopped parsley over the dish for a vibrant finish and a hint of herbaceous brightness. Serve the Cajun Shrimp and Steak Alfredo Pasta piping hot, ready to wow your dinner guests or delight your family with its bold layers of flavor.
How to Serve Cajun Shrimp and Steak Alfredo Pasta Recipe

Garnishes
Beyond the chopped parsley, you can sprinkle a little extra Parmesan to heighten the richness or even add a few red chili flakes if you want an extra touch of heat. A wedge of lemon on the side is also lovely for a quick citrus squeeze just before eating, enhancing the seafood’s flavor and balancing the creaminess beautifully.
Side Dishes
This pasta is a hearty, standalone meal, but pairing it with a crisp green salad or some roasted vegetables can add refreshing contrast. Garlic bread or warm, crusty bread is also ideal for mopping up every last bit of that luscious Alfredo sauce.
Creative Ways to Present
For a stunning presentation, serve this pasta in shallow white bowls so the colors of the shrimp, steak, and peppers pop. Garnish each plate with parsley and perhaps a sprig of thyme or basil. For a dinner party, consider plating individual portions with a drizzle of extra virgin olive oil and a zigzag of balsamic glaze alongside for a touch of elegance.
Make Ahead and Storage
Storing Leftovers
Store any remaining Cajun Shrimp and Steak Alfredo Pasta in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen when resting, although the pasta will absorb some sauce, so it might need a splash of cream or milk upon reheating.
Freezing
While you can freeze the leftovers, I recommend freezing the sauce and proteins separately from the pasta for best texture. The pasta tends to get mushy after freezing. Freeze in airtight freezer-safe containers for up to 1 month.
Reheating
To reheat, gently warm the pasta and sauce in a skillet over medium-low heat, adding a little cream or milk to loosen the sauce if needed. Stir frequently until heated evenly to keep the shrimp and steak from overcooking and getting tough.
FAQs
Can I substitute another type of pasta?
Absolutely! While fettuccine is ideal because of its wide shape that holds the sauce well, you can use penne, linguine, or even rigatoni. Just adjust the cooking time accordingly to maintain that perfect al dente bite.
How spicy is the Cajun seasoning in this recipe?
The Cajun seasoning provides a moderate level of heat that complements the creamy Alfredo sauce without overwhelming it. You can easily adjust the amount to suit your spice preference or use a mild blend if you prefer less heat.
Can I use cream alternatives?
Heavy cream is recommended for its richness and smooth texture, but if you want a lighter version, half-and-half or a full-fat coconut milk can be substituted with good results, although the flavor and consistency will be slightly different.
Is it necessary to cook the shrimp and steak separately?
Cooking them separately ensures that each protein cooks perfectly without overcrowding the pan. Shrimp cooks quickly and steak takes longer; this method prevents overcooking and maintains the ideal texture for both.
Can I prepare components ahead of time?
Yes! You can season and prep the shrimp and steak up to a day in advance. The sauce can also be made earlier and reheated gently. Just add everything together at the last minute to preserve freshness and flavor.
