Step‑by‑Step Instructions for Cajun Seafood Alfredo with Lobster and Crab
Step 1: Prepare the Pasta
Start by bringing a large pot of salted water to a rolling boil over high heat. Add in 8 ounces of fettuccine pasta and cook according to package instructions until al dente, typically about 8-10 minutes. Once done, reserve ½ cup of the pasta water for later, then drain the pasta in a colander and set it aside to keep warm.
Step 2: Sauté the Seafood
In a large skillet, melt 2 tablespoons of butter over medium heat, allowing it to foam slightly. Add 6 ounces of cooked lobster meat and 6 ounces of lump crab meat to the skillet, gently sautéing for 2-3 minutes until just warmed through. Keep an eye on the seafood to ensure it doesn’t overcook, then remove it from the skillet and set aside in a bowl.
Step 3: Create the Sauce Base
Using the same skillet, melt another 2 tablespoons of butter over medium heat. Add in 3 cloves of minced garlic, cooking for about 30 seconds until fragrant and soft—be careful not to burn the garlic! This aromatic mixture sets the foundation for your rich Cajun Seafood Alfredo sauce.
Step 4: Craft the Creamy Sauce
Pour in 1 ½ cups of heavy cream into the skillet, bringing it to a gentle simmer while stirring. Stir in 1 tablespoon of Cajun seasoning, mixing well to combine, and let it cook for 3-4 minutes. You should notice the sauce thickening to a velvety texture, which will beautifully coat your pasta later.
Step 5: Incorporate the Cheese and Seafood
Lower the heat and gradually mix in ¾ cup of grated Parmesan cheese, stirring until the cheese is completely melted and smooth. Then, return the sautéed lobster and crab to the skillet along with the reserved al dente fettuccine. Toss everything together, ensuring every piece of pasta is beautifully coated in the creamy sauce.
Step 6: Adjust the Consistency and Serve
Utilize the reserved pasta water, adding 1-2 tablespoons as needed to reach your desired sauce consistency. Taste and season with salt and pepper to elevate the flavors. Finally, garnish your decadent Seafood Alfredo with Lobster and Crab with fresh chopped parsley for a pop of color, and serve immediately while hot for an unforgettable meal.

Make Ahead Options
Preparing the Cajun Seafood Alfredo with Lobster and Crab ahead of time is a fantastic way to save time on busy weeknights. You can cook the pasta up to 24 hours in advance, just remember to drizzle a little olive oil over it to prevent sticking. The Alfredo sauce can also be made ahead and stored in the refrigerator for up to 3 days—simply reheat it gently on the stovetop, adding a splash of cream if it thickens too much. When ready to serve, sauté your seafood fresh for 2-3 minutes, then combine everything for a delicious meal that tastes just as indulgent as if it were made on the spot!

Cajun Seafood Alfredo with Lobster and Crab Recipe FAQs
What is the best way to select fresh seafood for this recipe?
Absolutely, when selecting your lobster and crab meat, look for sweet, juicy pieces. Fresh lobster should have a firm texture and a mild ocean scent; avoid any with dark spots all over. For crab meat, freshness matters—opt for fresh lump crab for the best flavor. If using frozen, ensure it’s fully thawed and drained to maintain quality.
How should I store my Cajun Seafood Alfredo leftovers?
For the best quality, store your leftovers in an airtight container in the fridge for up to 3 days. I recommend keeping the pasta and sauce separate to preserve that delightful texture. When you’re ready to enjoy again, reheat gently on the stovetop, adding a splash of cream or reserved pasta water to bring back that creamy sauce consistency!
Can I freeze Cajun Seafood Alfredo with Lobster and Crab?
Yes! You can freeze the sauce for up to 1 month. Ensure it’s cooled completely before transferring it to a freezer-safe container. I often freeze in smaller portions for convenience. When ready to use, thaw overnight in the fridge and reheat on the stovetop, stirring in a bit of cream to revive its luscious texture.
What should I do if my sauce becomes too thick?
If your sauce turns out thicker than expected, don’t worry! Simply add 1-2 tablespoons of the reserved pasta water or a splash of cream, stirring gently over low heat until you’ve achieved your desired consistency. This will also help to keep it rich and creamy, perfect for your Seafood Alfredo!
Are there any dietary considerations I should be aware of for my pets?
While the ingredients in this Cajun Seafood Alfredo are delicious for humans, many are not suitable for pets. Seafood can be a treat for some pets in moderation; however, the rich cream and butter should be avoided. Always consult your veterinarian before sharing any human food with your furry friends to ensure it’s safe for them.
