Gather all ingredients in a large mixing bowl. Combine softened butter, lobster meat, and crab meat.

Add lemon juice, minced garlic, Old Bay seasoning, and parsley to the bowl. Ensure butter is softened but not melted.

Mix the ingredients with a spatula or hand mixer until well combined and smooth, about 2-3 minutes.

Spoon the mixture onto a piece of plastic wrap, forming it into a log shape about 2 inches in diameter.

Roll the mixture tightly in the wrap, twisting the ends to secure it. Refrigerate for at least 2 hours.

After chilling, remove the log from the refrigerator and unwrap. Slice into rounds about half an inch thick.

Place slices on a serving platter and garnish with additional parsley and lemon wedges.
