I dunk frozen shrimp in cold water for 5–10 minutes, then peel and devein them. Keeping the tails on adds flavor and looks pretty on the plate.
I toss the shrimp with olive oil, garlic, kosher salt, and red pepper flakes. Letting it sit for 20 minutes helps the flavors sink in deeply.
Shrimp cooks fast—about 90 seconds per side. I remove them to a plate once opaque to avoid overcooking.
I melt butter with garlic in the skillet, then stir in white wine and lemon juice. It simmers until slightly thickened and fragrant.
Whisk in cold butter slowly for a creamy, velvety texture. This step makes the sauce luxurious without being heavy.
I return the shrimp to the pan for a quick reheat, then sprinkle parsley over the top for freshness and color.
