Step 1

In a bowl, toss shrimp with 1 teaspoon garlic and 1/2 teaspoon salt. Heat a large skillet over medium-high. Add oil and shrimp and cook until they begin to curl. Turn and cook until just opaque, about 2 minutes total. Transfer to a plate.

Step 2

Reduce heat to medium. Add remaining 1 tablespoon garlic and red-pepper flakes to skillet; cook until fragrant, about 15 seconds. Add wine, increase heat to high, and boil until reduced to about 2 tablespoons, 2 to 3 minutes.

Step 3

Add shrimp stock and lemon juice; boil 30 seconds, then remove from heat. Stir in butter to form an emulsified sauce. Return shrimp to skillet and toss to coat. Season with salt, pepper, and more lemon juice. Sprinkle with parsley and serve.
