Mustard Roasted Sea Bass Recipe


Whenever we host a formal dinner, I tend to serve a “surf and turf” as a main course. This means a combination of seafood and meat. And usually my choice of seafood is Chilean sea bass because it’s such a delicate and exquisite fish.

For this marinade, I mixed Dijon mustard, soy sauce and molasses. The key is to first form an outer crust while pan-searing the fish and then complete the cooking in the oven. The fish dish is fairly simple but so elegant!
