This Pacific cod cake recipe uses mashed potatoes to help bind the patties together, an Irish-inspired take on a simple fish cake recipe. Using mashed potatoes adds a satisfying density to the flaky lightness of the fish, as well as flavor and richness from any butter or cream that you’ve used to make the mashed potatoes.
To make these Irish-style Pacific cod cakes, you can either use fresh or leftover fish and mashed potatoes — it’s a great recipe for when you want to repurpose last night’s dinner, but it’s also one that you can make from scratch in about 30 minutes. Note that the recipe below assumes that you already have mashed potatoes on hand, but if you don't, you can make your favorite recipe for mashed potatoes as the Pacific cod is baking.
