Prepare the shrimp:
Thaw your frozen shrimp completely. Pat the shrimp dry with paper towels to remove any excess moisture.
Cook the garlic.
In a large skillet, melt the butter over medium heat. Add the minced garlic and red pepper flakes (if using). Cook for about 1 minute, stirring constantly, until the garlic is fragrant but not browned.
Cook the shrimp:
Add the shrimp to the skillet in a single layer. Cook for about 2–3 minutes on each side until the shrimp turn pink and opaque. Be careful not to overcook them, as shrimp cook quickly.
Add lemon and seasoning.
After cooking the shrimp, add the chicken broth or white wine. Add the lemon juice, lemon zest, salt, and pepper. Stir everything together and let it simmer for another 1-2 minutes to allow the flavors to meld.
Garnish and serve:
Remove the skillet from heat. Sprinkle the chopped parsley over the shrimp and give it one last stir. Serve the shrimp immediately, with lemon wedges on the side.
Serving Suggestions:
This dish pairs wonderfully with a side of rice, pasta, or a fresh salad. It also makes a great topping for simple garlic-butter pasta.
