This open-faced white fish sandwich is a decadent Alaskan twist on a classic tuna fish melt. The fish topping is made from Pacific cod or Pacific halibut from Alaska. Both Pacific cod and Pacific halibut are sustainable, lean protein options that are perfect to use as the topping for the melt. You can use leftover fish from a previous meal, or bake the white fish as you’re prepping the other ingredients for the melt.
The fish is flaked together with lemon and herbs for fresh flavor and celery for a bit of crunch. As a chef-inspired option, you can make a batch of pickled mustard seeds for a pop of texture and extra zestiness.
To give the melt an over-the-top flourish, you have the option to make a cheddar cheese sauce to pour over the fish. A simpler alternative is to melt sliced cheese over the open-faced sandwiches by finishing them under the broiler.
