Pat shrimp dry and coat generously with lemon pepper seasoning just before cooking.
Heat large skillet over medium-high heat. Add oil and heat until shimmering.
Sear shrimp in circular pattern for 2-3 minutes per side until golden and just cooked through. Remove to plate.
Reduce heat to medium-low. Add garlic and cook 30 seconds. Add butter gradually until melted and foaming.
Stir in lemon pepper seasoning and parsley. Return shrimp to pan and toss to coat completely.
Serve immediately with crusty bread for dipping in the golden butter sauce.
