What Makes This Cajun Shrimp Fettuccine Special
This isn’t your ordinary pasta dish – it’s a beautiful marriage of Italian comfort food and Louisiana spice that’ll have your taste buds dancing! The Cajun seasoning creates a flavor-packed crust on the shrimp while infusing the entire dish with that distinctive blend of paprika, garlic, and just the right amount of heat.
What really sets this recipe apart is the technique of cooking the shrimp first, then using those incredible pan drippings to build the alfredo sauce. Those little browned bits on the bottom of your pan? That’s pure flavor gold, my friend! The whole dish comes together in one pan, which means less cleanup and more time to enjoy this creamy, spicy masterpiece.

Ingredients
For the Cajun Seasoning Blend:
- 2 teaspoons paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1/2 teaspoon cayenne pepper (adjust to taste)
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt
For the Pasta and Shrimp:
- 1 lb large shrimp (21-25 count), peeled and deveined
- 12 oz fettuccine pasta
- 3 tablespoons butter, divided
- 2 tablespoons olive oil
- 4 cloves garlic, minced
- 1 1/2 cups heavy cream
- 1 cup freshly grated Parmesan cheese
- 2 tablespoons fresh parsley, chopped
- Salt and pepper to taste
- Lemon wedges for serving
Pro tip: Buy shrimp that’s already peeled and deveined if you’re short on time – it’s totally worth the extra cost for a weeknight dinner! And trust me on the fresh Parmesan – the pre-grated stuff just doesn’t melt the same way.
Cooking Method
Step 1: Get Your Pasta Water Going
Start by bringing a large pot of salted water to boil. I like to say the water should taste like the sea – don’t be shy with that salt! This is your chance to season the pasta from the inside out.
Step 2: Prepare Your Cajun Seasoning
While the water’s heating up, mix all your Cajun seasoning ingredients in a small bowl. Give it a taste – if you like more heat, add an extra pinch of cayenne. If you’re cooking for kids or prefer milder flavors, dial back that cayenne just a bit. This seasoning blend makes more than you’ll need, so store the extra in an airtight container for next time!
Step 3: Season and Cook the Shrimp
Pat your shrimp completely dry with paper towels – this is crucial for getting that beautiful golden sear. Toss the shrimp with about 2 tablespoons of your Cajun seasoning blend until they’re evenly coated.
Heat a large skillet (I love using my cast iron for this) over medium-high heat. Add the olive oil and let it get nice and hot. You’ll know it’s ready when the oil shimmers slightly.
Add the seasoned shrimp to the pan in a single layer – don’t overcrowd them! Cook for about 2-3 minutes per side until they’re pink and have that gorgeous golden crust. Here’s the secret: Don’t move them around too much! Let them develop that beautiful color. Remove the shrimp to a plate and set aside.
Step 4: Cook the Fettuccine
Drop your fettuccine into that boiling water and cook according to package directions until al dente. Pro tip: Save about 1 cup of that starchy pasta water before draining – you might need it to thin out your sauce later!
Step 5: Build That Amazing Alfredo Sauce
Here’s where the magic happens! In the same skillet you used for the shrimp (don’t clean it – those browned bits are flavor heaven!), reduce heat to medium and add 2 tablespoons of butter.
Add the minced garlic and cook for about 30 seconds until fragrant. Don’t let it brown – burnt garlic is nobody’s friend!
Slowly pour in the heavy cream, scraping up all those delicious browned bits from the bottom of the pan. Let the cream simmer gently for 2-3 minutes until it starts to thicken slightly.
Step 6: Add the Cheese and Bring It All Together
Remove the pan from heat (this prevents the cheese from getting grainy) and gradually whisk in the Parmesan cheese. Start with about half the cheese, whisk it in completely, then add the rest. The sauce should be smooth and creamy.
Add the drained fettuccine to the pan and toss everything together. If the sauce seems too thick, add a splash of that reserved pasta water – it works like magic to create the perfect consistency!
Step 7: The Grand Finale
Gently fold the cooked shrimp back into the pasta, along with any juices that accumulated on the plate. Add the remaining tablespoon of butter and the fresh parsley. Toss everything together one more time.
Taste and adjust seasoning with salt, pepper, and maybe a squeeze of fresh lemon juice to brighten everything up!
Chef’s Tips & Variations
Storage and Reheating: This pasta is definitely best enjoyed fresh, but if you have leftovers, store them in the refrigerator for up to 2 days. When reheating, add a splash of cream or milk to help bring the sauce back together – it tends to thicken up in the fridge.
Protein Variations: Don’t have shrimp? This recipe works beautifully with blackened chicken, andouille sausage, or even crawfish if you can get your hands on some! For chicken, slice it thin and cook it the same way as the shrimp.
Spice Level Adjustments: If you’re serving kids or prefer less heat, cut the cayenne in half and add some sweet paprika instead. Want more heat? A dash of hot sauce or extra cayenne will do the trick!
Vegetable Add-ins: I love stirring in some sautéed bell peppers and onions for extra color and flavor. Cook them right after the shrimp and before making the sauce. Baby spinach also wilts beautifully into the finished dish.
Wine Pairing: This rich, spicy dish pairs wonderfully with a crisp Sauvignon Blanc or a Pinot Grigio. The acidity cuts through the cream beautifully!
Make-Ahead Tip: You can mix up the Cajun seasoning blend days ahead and store it in your spice cabinet. It’s also fantastic on grilled vegetables, chicken, or fish!

This Cajun Shrimp Fettuccine Alfredo has honestly become one of my most-requested recipes from friends and family. There’s something so satisfying about twirling those creamy, spice-kissed noodles around your fork and getting that perfect bite with a plump, seasoned shrimp.
