Wild white fish gets a pop of flavor from a smoky, savory spice blend that you can make with basic pantry staples — dried oregano, garlic powder, onion powder, and smoked paprika. The paprika rub pairs beautifully with mild varieties of Alaskan white fish, including lingcod, yelloweye rockfish, Pacific halibut, and Wild Alaska Pollock. The dry seasonings bake into the mild fillet, adding color and interest to the dish. Any extra seasoning can be saved for the asparagus, which can cook alongside the fish, turning this into an easy sheet pan meal.
To finish the dish, don’t skip the homemade lemon-dill aioli. It’s a cool, creamy contrast to the smokiness of the fish. For a dairy-free version of the aioli, you can substitute more mayonnaise for the sour cream and Greek yogurt.
