Begin by tossing the pound of peeled and deveined shrimp with ¼ teaspoon of salt in a bowl. Allow the shrimp to sit for about 1 minute, then rinse thoroughly under cold water and pat them dry with paper towels.

In a small mixing bowl, combine 2 tablespoons of room temperature butter, 1 clove of finely minced or grated garlic, and 1 tablespoon of minced cilantro or parsley leaves. Next, add 1 ½ teaspoons of homemade Cajun seasoning. Use a fork to mix all ingredients until well combined.

Heat ½ tablespoon of olive oil in a large skillet over medium heat. Once the oil is shimmering, carefully add the seasoned shrimp in a single layer.

Lower the skillet's heat and immediately add the prepared Cajun butter to the shrimp in the skillet. Stir gently to ensure each shrimp is evenly coated and cook for another 1-2 minutes, until the shrimp are firm and fully opaque.
