- 8 oz fettuccine: The perfect pasta shape to hold onto the creamy Alfredo sauce with every bite.
- 1 lobster tail, cooked and chopped: Adds rich sweetness and an elegant touch to the seafood medley.
- 8 oz crab meat: Tender and delicate, crab brings a subtle ocean flavor that complements the other seafood.
- 1 salmon fillet, cooked and flaked: Brings a buttery texture and a hearty element to the dish.
- 2 cups heavy cream: The creamy backbone of the Alfredo sauce, giving it a luxurious mouthfeel.
- 1 cup Parmesan cheese, grated: Adds depth, saltiness, and a nutty flavor that perfectly balances the cream.
- 2 tbsp Cajun seasoning: Infuses the sauce with a smoky, spicy kick, elevating the seafood flavors.

How to Make Cajun Lobster, Crab, and Salmon Alfredo Recipe
Step 1: Cook the Pasta
Begin by cooking your fettuccine according to the package instructions until it’s perfectly al dente. You want it with a slight bite, so it holds up wonderfully against the creamy sauce. Drain the pasta carefully and set it aside while you work on the luscious Alfredo.
Step 2: Prepare the Cajun Alfredo Sauce
In a large skillet over medium heat, combine the heavy cream, minced garlic, and Cajun seasoning. Let them meld together gently; the garlic will infuse the cream, while the Cajun seasoning starts to release those smoky, spicy aromas that make this sauce so irresistible.
Step 3: Melt in the Parmesan Cheese
Once the cream mixture is warm, slowly stir in the grated Parmesan cheese. Keep stirring until it melts completely into a smooth and creamy sauce. This step transforms the cream into a rich Alfredo base with a velvety texture that clings lovingly to the pasta and seafood.
Step 4: Add the Seafood
Next, add the chopped lobster tail, crab meat, and flaked salmon right into the sauce. Cook everything together just until the seafood is heated through. This step is crucial—overcooking can dry out your seafood, so keep an eye on it to ensure it stays tender and juicy.
Step 5: Combine with Pasta and Season
Now, toss the cooked fettuccine into the skillet, mixing it well to coat every strand with that creamy, spicy sauce. Taste and adjust the seasoning with salt and pepper as needed so every bite is perfectly balanced.
Step 6: Serve and Garnish
Dish up your pasta and sprinkle it generously with chopped green onions for a fresh burst of flavor and a pop of color. Your Cajun Lobster, Crab, and Salmon Alfredo Recipe is now ready to enjoy!

Garnishes
While the dish is flavorful on its own, adding garnishes like freshly chopped green onions or even a sprinkle of crushed red pepper flakes can add extra layers of aroma and a touch of heat. A little fresh parsley can also brighten the plate beautifully.
Side Dishes
This decadent pasta pairs wonderfully with light, crisp sides such as a simple mixed green salad dressed with lemon vinaigrette or roasted asparagus. Garlic bread or a warm baguette is perfect for soaking up every last bit of that divine sauce.
Creative Ways to Present
For a special occasion, consider plating the Cajun Lobster, Crab, and Salmon Alfredo Recipe in individual shallow bowls, topped with a lemon wedge for an optional citrus zest. You could also sprinkle toasted breadcrumbs on top for a delightful crunch that contrasts beautifully with the creamy pasta.
Make Ahead and Storage
Storing Leftovers
Keep any leftovers in an airtight container in the refrigerator. This recipe reheats well within 2 days, but some of the seafood might lose a bit of its fresh texture, so try to enjoy it sooner rather than later.
Freezing
Because of the cream and seafood combination, freezing this dish is not ideal, as the sauce can separate and the seafood texture may degrade. If you must freeze it, do so in a tightly sealed container and expect some difference in quality upon thawing.
Reheating
Gently reheat leftovers in a skillet over low heat, adding a splash of cream or milk to revive the sauce’s creaminess without drying out the pasta or seafood. Avoid microwaving if possible, as it can cook unevenly and toughen the seafood.
FAQs
Can I use frozen seafood for this recipe?
Yes, you can use frozen lobster, crab, and salmon, but be sure to thaw them completely and drain any excess moisture before adding them to the sauce to avoid a watery dish.
Is this recipe very spicy?
The Cajun seasoning adds a pleasant warmth and smoky flavor, but it’s not overpoweringly spicy. If you prefer milder tastes, start by adding 1 tablespoon of seasoning and adjust up from there.
Can I substitute the heavy cream with a lighter option?
For the best creamy texture, heavy cream is recommended. However, you can try half-and-half or a combination of milk and cream cheese, though the sauce may be less rich and thick.
What type of Parmesan cheese works best?
Freshly grated Parmesan cheese yields the best flavor and texture for this recipe. Pre-grated cheese can be used in a pinch but may not melt as smoothly.
Can I prepare parts of this recipe in advance?
You can cook and flake the salmon ahead of time and chop the lobster tail. Keep the seafood refrigerated until ready to add to the sauce to save time during your cooking.
