Cajun Shrimp Fettuccine Alfredo is pure comfort in a bowl and the kind of meal that never leaves leftovers behind at my house. The blend of creamy sauce with juicy shrimp and a kick of spice makes it the pasta recipe friends always ask me to bring to parties.
This dish made me fall in love with Cajun spice all over again. The first time I cooked it, there were barely any leftovers and now everyone immediately claims seconds.
Ingredients

- Herbes de Provence or Italian seasoning: These herb blends add balance and hints of floral notes
- Paprika: Brings warm color and sweet pepper flavor Smoked paprika is even better if you want a bolder dish
- Lemon pepper: Lifts the whole recipe with citrus notes Use a fresh blend for real zing
- Olive oil: Keeps shrimp juicy and coats pasta for richer flavor
- Butter: Gives the sauce a luxurious base Unsalted is best so you can control saltiness
- Minced garlic: Use fresh garlic if you can for real punch

Step-by-Step Instructions
- Season the Shrimp:
- Mix the shrimp well with onion powder garlic powder Herbes de Provence or Italian seasoning lemon pepper paprika and half the Cajun seasoning Make sure every piece is coated for the fullest flavor
- Cook the Shrimp:
- Heat olive oil in a wide pan on medium high Once hot add the seasoned shrimp Cook them only until they turn pink and opaque which should take about two to three minutes per side Immediately take them out so they do not overcook and get rubbery
- Rest the Shrimp:
- Place the cooked shrimp on a plate and tent loosely with foil This helps them stay warm and juicy for later
- Start the Sauce Base:
- Add the butter to the same pan Let it melt fully so everything from the shrimp mixes in
- Sauté the Garlic:
- Toss in the minced garlic and stir constantly for about thirty seconds You want it just fragrant not browned
- Deglaze with Wine:
- Pour in the white wine or chicken broth Using a wooden spoon scrape the pan bottom to loosen the tasty brown bits Let the liquid simmer to reduce by half which builds the sauce’s complexity
- Pour in the Cream:
- Slowly add the heavy cream stirring constantly Keep the heat gentle so it does not scald
- Simmer and Season:
- Bring the sauce just to a light simmer then stir in the Parmesan cheese plus the rest of your Cajun seasoning Lower the heat and simmer for five to six minutes Stir often so it stays smooth and thickens perfectly
- Adjust Seasoning:
- Taste the sauce and add more salt pepper or Cajun spice until it matches your flavor cravings
- Combine and Toss:
- Add the cooked fettuccine directly into the sauce plus the shrimp if you want them coated Gently toss everything until noodles are well coated and the shrimp are evenly distributed
- Garnish and Serve:
- Top with plenty of fresh chopped parsley right before serving for a final pop of flavor and color

The Parmesan is always my favorite part because it adds a savory depth that ties the whole dish together My family always argues over who gets to scrape the pan for the last bits of the creamy sauce
Storage tips
Keep leftovers in a tightly sealed container in your fridge for up to three days. Add a splash of cream when reheating to make the sauce silky again. I do not recommend freezing this pasta because the cream can separate and turn grainy.
Ingredient substitutions
Chicken can easily replace shrimp if you want to switch things up. Penne or linguine work well if you do not have fettuccine on hand. Cauliflower cream or coconut cream can be swapped for heavy cream to make it dairy free though the sauce will be a little lighter.
Serving suggestions
This pasta is rich and works best with tangy salads like arugula with lemon dressing. Serve slices of toasted garlic bread on the side for dipping. For an extra fancy touch try a sprinkle of extra Cajun seasoning and a squeeze of lemon right before eating.

Cultural context
Cajun cuisine comes from French Acadian traditions in Louisiana. It is famous for bold flavorful spices and seafood. This dish blends two worlds the indulgence of Alfredo with the punchy flavors of Cajun shrimp to create something uniquely comforting and festive.
