Preparation Phase & Tools to Use
Before diving into the cooking process for your Cajun Seafood Alfredo, it’s essential to prepare your kitchen and gather all necessary tools and ingredients. Start by ensuring your workspace is clean and organized. This will make your cooking experience smooth and enjoyable. Here’s a list of essential tools you’ll need for this recipe:
- Large pot for boiling pasta
- Large skillet for making the sauce and cooking seafood
- Measuring cups and spoons for accurate ingredient measurements
- Wooden spoon for stirring
- Colander for draining pasta
- Sharp knife and cutting board for chopping parsley and garlic
Once you have your tools ready, lay out all your ingredients. Measuring and preparing everything beforehand will streamline the cooking process. Don’t forget to set your water on high to boil while you prep the seafood, so you’re maximizing your time!

Ingredients
- 12 oz fettuccine pasta
- 1 cup cooked lobster meat (preferably from lobster tails)
- 1 cup lump crab meat
- 1 1/2 cups heavy cream
- 4 tablespoons butter
- 3 cloves garlic, minced
- 1 cup freshly grated Parmesan cheese
- 1 tablespoon Cajun seasoning
- 2 tablespoons chopped fresh parsley
- Salt, to taste
- Black pepper, to taste
Instructions
Step 1: Cook the Fettuccine
Start by bringing a large pot of salted water to a rolling boil. Add the fettuccine pasta and cook per the package instructions until it reaches al dente (usually about 8-10 minutes). Once cooked, drain the pasta but be sure to reserve 1/2 cup of the pasta water. This starchy water is an essential ingredient that helps to create a creamy sauce!
Step 2: Sauté the Seafood
While your pasta is cooking, take the time to sauté the seafood. In a large skillet, melt 2 tablespoons of butter over medium heat. Once melted, add in the lobster meat. Cook it for about 3-4 minutes until it’s fully opaque and curled. Then, gently add the crab meat to the skillet, stirring just until warmed through. After a few minutes, carefully remove the seafood mix from the skillet and set it aside on a plate.
Step 3: Prepare the Alfredo Sauce
In the same skillet, without washing it out, melt the remaining 2 tablespoons of butter over the medium heat. Add minced garlic and sauté for around 30 seconds until aromatic. Following that, pour in the heavy cream and let it come to a gentle simmer. Allow it to cook for about 4-5 minutes, stirring occasionally, until the sauce starts to reduce slightly. This reduction will give your sauce that rich, thick consistency we all love.
Step 4: Season the Sauce
Next, stir in Cajun seasoning along with salt and black pepper. After that, add the freshly grated Parmesan cheese to the mixture. Continuously stir until the cheese is completely melted and incorporated, which should take just a couple of minutes. You should have a gloriously creamy and smooth sauce, perfect for coating your pasta!
Step 5: Combine Pasta and Sauce
Now it’s time to bring everything together. Add the drained fettuccine into the sauce pan and toss until every strand is beautifully coated. If you find the sauce too thick, this is where that reserved pasta water comes in handy, allowing you to loosen it to your desired consistency.
Step 6: Finish with Seafood
Finally, gently fold in the sautéed lobster and crab meat into the pasta and sauce mixture. Let everything heat through on the stovetop for an additional 1-2 minutes. This ensures the seafood is warmed nicely without overcooking it, preserving the tender texture.

Variations
- Protein: Substitute shrimp or scallops for a delightful change of pace.
- Vegetables: Toss in frozen peas or sautéed spinach for added color and nutrition.
- Spices: Adjust the level of Cajun seasoning for more or less heat. You could also add a hint of smoked paprika for a unique accent!
Cooking Notes
- Always taste your sauce throughout the cooking process to ensure the seasoning is just right.
- Leftover Alfredo can be reheated gently on the stove with a splash of cream to restore its consistency.
Serving Suggestions
- Serve with crusty garlic bread for a delightful contrast.
- A side salad with a light vinaigrette pairs beautifully to balance the richness of the dish.
Tips
- Using fresh seafood will dramatically enhance the flavor of your dish.
- Grating your own Parmesan cheese yields a better texture than pre-grated versions for this creamy sauce.

Can I make this dish ahead of time?

Can I use frozen seafood?
Yes! Just ensure it’s completely thawed and drained before cooking to avoid excess moisture in your dish.
How can I store leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat on the stove with a bit of cream to freshen it up.
