4 servings
45 minutes
Potato casserole with herring, known as Kalalaatikko, is a cozy dish from Dutch cuisine that combines the tenderness of potatoes with the zest of lightly salted herring. Historically, such casseroles were popular among sailors and fishermen as herring was one of the most accessible and nutritious foods. The flavor of the dish is rich and multifaceted: the creamy texture of the sauce highlights the salty freshness of the fish, while aromatic onions add a hint of sweetness. Kalalaatikko is perfect as a standalone dish or as a hearty side for dinner. It is served hot with a crispy golden crust, and fresh parsley adds brightness to it. This is not just a casserole — it embodies comfort, traditions, and a harmonious blend of simple ingredients that turn an ordinary dinner into a culinary journey.
