Melt the butter in a spacious skillet set over medium-high heat. Introduce the shrimp and season generously with salt, pepper, and Italian seasoning. Sauté for 3 to 5 minutes, stirring intermittently, until the shrimp turn pink and opaque. Incorporate the minced garlic and continue cooking for an additional minute. Pour in the lemon juice, stir through the chopped parsley, and serve immediately.
