Spice it up: Stir in the red pepper flakes and cook for another 30 seconds.
Cook the shrimp: Add the shrimp to the skillet in a single layer. Cook for 2-3 minutes on one side until they turn pink, then flip and cook for another 2-3 minutes.
Add lemon juice: Once the shrimp are cooked through, remove from heat and stir in the lemon juice. Season with salt and pepper to taste.
Garnish and serve: Transfer the shrimp to a serving dish and sprinkle with chopped parsley.
Notes
Ensure the skillet is hot enough before adding the shrimp to achieve a nice sear and avoid overcrowding the pan.
