While the shrimp is your main ingredient, prep work is minimal here—that's the beauty of this dish. Lightly salt the shrimp in a colander, let it sit for 1 minute to help draw out excess moisture, then rinse and thoroughly pat dry with paper towels. Dry shrimp will sear beautifully rather than steam. While the shrimp dries, mince your garlic and herbs, then combine the room-temperature butter, minced garlic, minced cilantro or parsley, Cajun seasoning, and smoked paprika in a small bowl, stirring until well blended. Having the butter mixture ready means you can work quickly once the shrimp hits the pan.

Heat the olive oil in a large skillet over medium-high heat until it shimmers and just begins to smoke lightly—this ensures a good sear. Add the dried shrimp in a single layer and let them cook undisturbed for about 1 minute. I like to resist the urge to move them around; this initial rest develops a light golden crust on one side, which builds flavor. The shrimp don't need to be fully cooked at this stage—they'll finish cooking when the butter is added.

Lower the heat to medium, then add the Cajun butter mixture from Step 1 directly to the skillet. Stir gently for 1 to 2 minutes, allowing the butter to melt and coat the shrimp while the residual heat finishes cooking them through. The shrimp are done when they're opaque and firm—they should curl slightly and reach an internal temperature of about 145°F. Remove from heat and finish with a squeeze of fresh lemon juice, which brightens the rich, savory flavors of the butter and spices. Serve immediately while the butter is still warm and glossy.
