How to Make This Cajun Seafood Alfredo Recipe

This recipe comes together in about 30 minutes, so it’s PERFECT for a weeknight dinner that feels fancy.

Cook Your Pasta

Bring a big pot of salted water to a boil and cook the pasta according to the package instructions. Drain it, toss it with a little olive oil (so it doesn’t stick), and set it aside.

PRO TIP: Don’t rinse the pasta—those starchy vibes help the sauce stick like glue!

Prep Your Seafood

Season the shrimp with Cajun seasoning and give them a little massage. Heat olive oil in a large skillet over medium heat, then cook the shrimp for about 2 minutes per side. They’ll turn pink and slightly curled.

Make That Creamy Alfredo Sauce

In the same skillet, melt the butter over medium heat. Toss in the minced garlic and let it sauté until it smells AMAZING (about 1 minute). Slowly add the heavy cream, whisking as you go, and bring it to a gentle simmer. I used our Cajun Alfredo Sauce Recipe to make it extra flavorful

Stir in the Parmesan cheese, smoked paprika, and a pinch of Cajun seasoning. Keep stirring until the sauce is creamy and smooth—NO LUMPS ALLOWED!

Combine It All

Add the cooked pasta to the skillet, tossing to coat every strand in that luscious Alfredo sauce. Gently fold in the shrimp , making sure everything gets a good dunk in the sauce.

Serve and GARNISH!

Transfer your masterpiece to a serving dish. Top it with parsley, extra Parmesan, and a quick squeeze of lemon juice if you’re feeling fancy.

BOOM. Dinner is SERVED.

Pro Tips for the Perfect Cajun Seafood Alfredo

1. Don’t Overcook the Seafood. Shrimp and crab cook FAST, so keep an eye on them. Overcooked seafood = rubbery sadness.
2. Use Fresh Parmesan. The pre-grated stuff doesn’t melt as well and can make your sauce grainy.
3. Adjust the Heat. Like it spicier? Add a pinch of cayenne. Need it milder? Use less Cajun seasoning.
