Blackened Shrimp offers a quick and flavorful way to enjoy seafood with minimal fuss. The homemade blackened seasoning delivers a perfect balance of smoky, spicy, and aromatic notes while the shrimp cook quickly to a crisp and buttery finish that is simply irresistible.
I first tried this recipe on a busy weeknight and was amazed at how quickly it came together without sacrificing flavor. It quickly became a go-to in my kitchen whenever I want something satisfying but easy.
Ingredients
- One teaspoon kosher salt: to bring out natural flavors
- One teaspoon onion powder: adds subtle sweetness and depth
- One tablespoon paprika: provides a smoky base and vibrant color
- One teaspoon cayenne pepper: delivers a balanced heat
- One teaspoon ground black pepper: for warmth and spice complexity
- Half teaspoon dried basil: offers an earthy herbal note
- Half teaspoon dried oregano: adds a Mediterranean touch
- Half teaspoon dried thyme: enhances overall aroma
- Two pounds of peeled and deveined shrimp: ideally 13 to 15 count for a meaty bite
- Six tablespoons unsalted butter melted: divided for cooking and finishing
Step-by-Step Instructions
- Prepare Blackened Seasoning:
- Combine kosher salt, onion powder, paprika, cayenne pepper, black pepper, basil, oregano, and thyme in a small bowl. Mix thoroughly with a fork until well blended to ensure even seasoning distribution.
- Season Shrimp:
- Place shrimp in a large bowl and sprinkle the blackened seasoning over them. Toss gently to coat all shrimp evenly with the spice blend, making sure every piece absorbs the flavor.
- Cook First Half:
- Heat a large skillet over high heat until very hot. Add four tablespoons of melted butter. Place half the shrimp in the skillet in a single layer. Cook for two minutes on each side or until shrimp are crisp on the outside and opaque throughout.
- Cook Second Half:
- Remove the cooked shrimp from the skillet and set aside. Add the remaining shrimp to the skillet and cook again for two minutes per side until perfectly blackened and cooked through.
- Finish and Toss:
- Add the remaining two tablespoons of melted butter to the skillet. Return all the cooked shrimp to the pan and toss gently to coat every piece in the buttery sauce. Serve immediately with sliced French bread or your favorite side.

My favorite part of this dish is the blackened seasoning which I learned to toast lightly before mixing for even deeper flavor. It reminds me of summer evenings cooking on the stovetop while catching up with friends.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to two days. Reheat gently in a skillet over medium heat to maintain crispness and prevent overcooking the shrimp. Avoid microwaving as it may make shrimp rubbery.
Ingredient Substitutions
If you prefer dairy free use olive oil instead of butter but add a little extra seasoning to compensate for flavor. For milder heat reduce or omit the cayenne pepper. Fresh herbs like oregano or thyme can replace dried if you adjust quantities to taste.
Serving Suggestions
Serve with crusty French bread to soak up the buttery juices. Pair alongside steamed greens, a crisp green salad, or roasted vegetables for a balanced meal. A squeeze of fresh lemon brightens the dish and complements the blackened spices beautifully.

Cultural Context
Blackening is a cooking technique that originated in Cajun cuisine, relying on a hot skillet to create a flavorful crust. This method transforms simple shrimp into a dish bursting with smoky, spicy, and aromatic notes, embodying the rich culinary heritage of the American South.
