Peel and devein the shrimp if necessary.
Heat a skillet on medium-high heat. Add the butter and melt. Then add your garlic and sauté until fragrant, about 1 minute.
Add your shrimp in a single layer along the bottom of the skillet. Let the shrimp cook for 1-2 minutes until it easily moves when you lift it with tongs.
Once flipped, cook the second side for an additional 1-2 minutes. Keep an eye on the thickest part of the shrimp, and when that turns pink, it’s done.
Add a big squeeze of fresh lemon juice, a generous sprinkle of parsley, and you’re ready to serve!
