Combine 2 pounds extra-large or jumbo shrimp in a large bowl with 1 tablespoon minced garlic, 2 teaspoons Cajun seasoning, ½ teaspoon paprika, ¼ teaspoon dried thyme, ½ teaspoon ground black pepper, ½ teaspoon salt, and ¼ teaspoon cayenne pepper.
Heat a large 14-inch skillet over medium heat, then add ½ cup unsalted butter and cook until melted. Add the shrimp and cook for 1-2 minutes, until the shrimp start to turn pink and opaque, but aren't fully cooked.
Add ¼ cup Worcestershire sauce, 2 tablespoons fresh lemon juice, and 4-5 slices fresh lemon. Simmer for 2-3 minutes, until fragrant and slightly thickened, then remove from the heat.
Top with ⅓ cup sliced green onions and serve immediately.
Notes
Storage, Reheating, & Make Ahead Instructions
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating: Reheat gently in a skillet over medium heat for 2–3 minutes until warmed through. Avoid the microwave, which can make shrimp rubbery.
Freezer: If using fresh (never frozen) shrimp, toss with the seasonings and freeze in a freezer-safe bag for up to 3 months. Thaw completely, then continue with step 2 as directed.
Make Ahead: Toss the shrimp with the seasonings, then store in an airtight container or a zip-top bag in the refrigerator for up to 24 hours before cooking.
