Creamy Blackened Shrimp Fettuccine Alfredo

This creamy blackened shrimp fettuccine Alfredo brings together a velvety garlic parmesan sauce and spicy charred shrimp for a dinner that feels special but comes together in about 30 minutes.

The sauce is rich, silky, and clings to every ribbon of pasta, while the shrimp get a dark, smoky crust from the cast iron skillet. It is the kind of meal that makes any weeknight feel like a restaurant night.

Alfredo is all about the sauce: butter, cream, and parmesan melted into a lush, glossy coating for pasta. Here, that classic gets a bold upgrade with blackened shrimp—jumbo shrimp tossed in a spicy seasoning blend and seared in a screaming-hot cast iron skillet until charred and juicy.

The contrast of the cool, creamy pasta and the fiery, smoky shrimp is irresistible. This recipe walks through each step, from seasoning and searing the shrimp to building the sauce and tossing the pasta, so every element turns out perfectly.

Ingredients

Why this recipe works

The blackening method creates a deeply flavorful crust on the shrimp in just minutes.

High heat in a cast iron skillet chars the spices, locking in moisture and adding a smoky kick that balances the richness of the Alfredo sauce. Cooking the shrimp first and removing them keeps them from overcooking in the sauce.

The Alfredo sauce relies on a simple technique: simmer cream, then melt in parmesan off the heat. This gentle approach prevents the cheese from turning gritty and keeps the sauce silky.

Tossing the pasta directly into the sauce, rather than pouring sauce over pasta, ensures every strand is coated and the sauce is perfectly seasoned.

Notes and substitutions

Use freshly grated parmesan from a block, not the pre-shredded kind. Pre-shredded cheese often contains anti-caking agents that prevent it from melting smoothly, leading to a grainy sauce. For the best flavor, grate the cheese yourself just before cooking.

Blackening seasoning is a blend of paprika, cayenne, garlic powder, onion powder, and herbs. It is widely available, but you can make your own. Adjust the amount of cayenne to control the heat. Jumbo shrimp (16-20 count per pound) work best; they stay juicy and present nicely on the pasta.

• fettuccine: Use tagliatelle or linguine; cook according to package directions until al dente.
• heavy cream: For a lighter sauce, use half-and-half, but the sauce will be less thick and may need extra simmering.
• blackening seasoning: Make your own with paprika, cayenne, garlic powder, onion powder, thyme, and oregano.
• parmesan: Use pecorino romano for a sharper, saltier flavor.
