Instructions

- Season The Fish:
- Pat the rockfish dry with paper towels then sprinkle the Old Bay seasoning and garlic salt inside the cavity and all over the skin This layers the flavors thoroughly

Old Bay is my secret weapon for making seafood approachable and fun at home Whenever I use it I’m reminded of casual summer dinners by the coast, where simple things like fresh fish and a squeeze of lemon make any meal a memory.
