In a small bowl, combine the softened butter, fresh lemon juice, minced garlic, chopped parsley, fresh thyme leaves, and red pepper flakes. Mix until well incorporated. This is your zesty herb butter.

Pat the shrimp thoroughly dry with paper towels. Season them evenly with sea salt and black pepper.

Heat the olive oil in a large skillet over medium-high heat until shimmering.

Add the seasoned shrimp to the hot skillet in a single layer, ensuring not to overcrowd the pan. Cook undisturbed for 1-2 minutes, until the undersides begin to turn pink and develop a light sear.

Flip the shrimp. Immediately add dollops of the zesty herb butter around the shrimp in the pan. Continue to cook for another 1-2 minutes, basting the shrimp with the melting butter sauce, until they are opaque and cooked through.

Remove from heat. Taste and adjust seasoning if necessary. Serve immediately, spooning any extra pan sauce over the shrimp.
