Prepare the Shrimp:
Pat the shrimp dry with paper towels and season with salt and black pepper.
Heat the Skillet:
In a large skillet, heat olive oil over medium-high heat.
Cook the Shrimp:
Add the shrimp to the skillet in a single layer. Cook for 1-2 minutes per side until pink and opaque. Remove shrimp and set aside.
Make the Garlic Butter Sauce:
Reduce heat to medium and add butter to the skillet. Once melted, stir in garlic and red pepper flakes. Cook for 1 minute until fragrant.
Combine and Finish:
Return the cooked shrimp to the skillet, tossing to coat in the garlic butter sauce. Stir in lemon juice and parsley.
Serve:
Serve immediately with your choice of pasta, rice, or crusty bread to soak up the sauce.
