Pat the shrimp dry and season with salt and black pepper.
Heat a large skillet over medium heat. Add the olive oil and 1 tablespoon of the butter.
Add the shrimp in a single layer and cook for 1 to 2 minutes per side, until pink and lightly golden. Remove and set aside.
In the same skillet, add the minced garlic and cook for about 30 seconds until fragrant.
Pour in the white wine and lemon juice. Simmer for 1 to 2 minutes to reduce slightly.
Add the remaining butter and chili flakes, if using. Stir until the butter melts into the sauce.
Return the shrimp to the skillet and toss to coat.
Add the chopped parsley and cook for another 30 seconds to 1 minute, just until heated through.
Serve immediately with baguette or bread.
