Combine all ingredients (except for fish) in a medium-sized airtight mixing bowl. Add cod and marinate for 24 hours. If possible, flip half way through marinade time to allow even flavor distribution.
Preheat oven to 450 degrees F; prepare a baking sheet with parchment paper. Remove cod from marinade and bake on the center rack for 7-9 minutes, until cod is opaque and flakes easily.
