Instructions

1. Step 1: Preheat oven to 425°F. Using kitchen shears, cut down the center of the top shell of 4 lobster tails and gently lift the meat to rest on top of the shell.
2. Step 2: In a small bowl, combine 6 tbsp melted unsalted butter, 4 minced garlic cloves, 2 tsp Cajun seasoning, 1 tbsp lemon juice, 1 tsp paprika, 1/2 tsp salt, and 1/4 tsp black pepper. Stir well.
3. Step 3: Place lobster tails on a rimmed baking sheet. Brush the garlic butter mixture generously over the lobster meat on each tail.
4. Step 4: Roast in the oven for 12-14 minutes until lobster meat is opaque and slightly firm to the touch, basting once halfway through with reserved butter.
5. Step 5: Remove from oven, sprinkle 2 tbsp chopped fresh parsley over the lobster tails, and serve immediately with lemon wedges if desired.
