Pat the shrimp dry with paper towels and season with a little salt.
In a large skillet, heat the olive oil over medium heat.
Add the thinly sliced garlic and cook until it becomes fragrant and golden brown, but not burnt. This should take about 1-2 minutes.
Increase the heat to medium-high and add the shrimp to the skillet.
Cook the shrimp for about 2-3 minutes on one side until they start to turn pink.
Add the red pepper flakes and dry sherry or white wine (if using) to the skillet.
Stir the shrimp and cook for another 2-3 minutes until they are fully cooked and opaque.
Remove the skillet from heat and sprinkle the shrimp with chopped fresh parsley.
Enjoy your meal!
