What Is Blackened Shrimp?

Blackening is a cooking technique popularized in Cajun cuisine.

Shrimp are coated in a flavorful seasoning mixture and cooked over high heat until a dark, flavorful crust forms. Contrary to what the name suggests, blackened food isn’t burnt. Instead, the spices caramelize and create a smoky, deeply flavorful exterior.

The result is shrimp that are:

• Juicy inside
• Boldly seasoned
• Slightly spicy
• Packed with flavor

When paired with Alfredo sauce, the contrast becomes truly exceptional.

Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil.

Cook fettuccine according to package instructions until al dente.

Reserve ½ cup pasta water.

Drain and set aside.

2. Season the Shrimp

In a bowl combine:

• Smoked paprika
• Garlic powder
• Onion powder
• Oregano
• Thyme
• Cayenne
• Salt
• Black pepper

Toss shrimp with olive oil and seasoning blend.

Coat evenly.

3. Blacken the Shrimp

Heat a large skillet over medium-high heat.

Cook shrimp for 2–3 minutes per side.

Remove when fully cooked and slightly charred.

Set aside.

4. Prepare the Alfredo Sauce

Reduce heat to medium.

Melt butter in the same skillet.

Gently toss or serve shrimp on top.

Tips for Perfect Blackened Shrimp

Use Large Shrimp

Larger shrimp remain juicy and are easier to cook evenly.

Don’t Overcook

Shrimp cook quickly and become rubbery if left too long.

Heat the Pan Properly

A hot skillet creates the characteristic blackened crust.

Use Fresh Parmesan

Freshly grated parmesan melts more smoothly and creates a better Alfredo sauce.

Flavor Variations

Extra Spicy Version

Increase cayenne pepper and add crushed red pepper flakes.

Garlic Lovers Version

Double the garlic in both the seasoning and sauce.

Lemon Alfredo

Add fresh lemon juice and zest.

Cajun Chicken Alfredo

Replace shrimp with blackened chicken.

Seafood Alfredo

Add scallops and crab meat.

Best Side Dishes

Serve this pasta with:

• Garlic bread
• Caesar salad
• Roasted asparagus
• Steamed broccoli
• Bruschetta
• Grilled zucchini
• Dinner rolls

Make-Ahead Tips

While Alfredo sauce is best fresh, you can prepare the shrimp seasoning blend and clean the shrimp in advance.

This helps reduce cooking time significantly.

Storage Instructions

Refrigerator
