Directions

1. In a large skillet, heat the oil over medium-high heat until it shimmers. Season the shrimp with salt and pepper, then put them in the skillet in a single layer. Cook, undisturbed, until the bottoms of the shrimp begin to turn pink, about 1 minute. Flip the shrimp over and cook until almost cooked through, about 1 minute more. Transfer the shrimp to a plate and set aside.
2. Reduce the heat to medium, add the garlic, pepper flakes and a little more oil if the pan seems dry; cook, stirring often, until the garlic just starts to turn golden, about 1 minute. Add the wine, scraping up any caramelized bits from the bottom of the pan, and simmer until most of the wine has evaporated.
3. Whisk in the butter one piece at a time, then season the sauce with salt and lemon juice from one lemon half. Add the cooked shrimp, any juices accumulated on the plate, the lemon zest and parsley (if using) and toss together until the shrimp are warmed through, about 1 minute. Serve with lemon wedges, if you like.
