About Plokkfiskur with Potatoes
Plokkfiskur is a traditional Icelandic dish made from fresh fish, potatoes and a creamy béchamel sauce. This rustic plateful mirrors an Icelandic food culture built on the country’s abundant fisheries. It is most often served as a family meal and is perfect for cold winter days, bringing warmth and a sense of comfort to the table. The dish is not only tasty but also nourishing and wholesome, which makes it an ideal choice for anyone who loves fish.
Ingredients (serves 1–2)
- 250 g fish fillet (cod or haddock, for example)
- 300 g potatoes
- 1 onion
- 2 tablespoons butter
- 2 tablespoons plain flour
- 300 ml milk
- Salt and pepper
- Fresh herbs (parsley, for example)
Shopping for the ingredients
When shopping for plokkfiskur, take care to choose fresh ingredients so the flavour is at its best. The fish should be as fresh as possible and ideally bought from a local fishmonger. The potatoes want to be firm and unblemished, while the onion should be aromatic and crisp. Check that the milk is fresh too, as it is what gives the béchamel its creaminess.
Preparing the dish
Before you start cooking, get all the ingredients ready. That means peeling and cutting the potatoes and bringing them to the boil in a pan of water. The fish should be cut into evenly sized pieces so that it cooks through at the same rate. Chop the onion finely so it distributes well through the sauce and has a chance to release its sweet aroma.
Step-by-step instructions
- Cook the potatoes in lightly salted water until soft, then drain and mash them.
- While the potatoes cook, heat the butter in a pan and sweat the chopped onion until translucent.
- Add the flour and stir until you have a smooth paste.
- Slowly stir in the milk and bring to the boil, stirring constantly, until the sauce thickens.
- Add the fish to the sauce and cook gently until just done through.
- Fold the mashed potatoes into the fish sauce and season to taste with salt and pepper.
Gluten-free / lactose-free version
To make plokkfiskur gluten-free, swap the flour for an alternative such as cornflour or rice flour. For a lactose-free version, use plant-based milk and lactose-free butter, which deliver the same creamy result. These adjustments let people with intolerances enjoy the dish without giving up any of the flavour. Do check that every other ingredient you use is likewise gluten- and lactose-free.
Tips for vegans and vegetarians
For a vegan version of plokkfiskur, replace the fish with tofu or seitan to achieve a comparable texture. Instead of dairy milk, use a plant-based alternative such as cashew or soya milk for the béchamel. The butter can be swapped for vegan margarine as well. That way vegans can enjoy this traditional dish while the recipe still meets high expectations on flavour.
More tips and tricks
One of the best ways to make plokkfiskur your own is to experiment with herbs and spices. Add thyme or dill, for instance, for an extra lift. Using smoked fish can also give the dish an intriguing edge. Another tip is to freeze leftover portions in small ovenproof dishes, so this hearty treat is always within reach — the same trick works well with a batch of Fiskisúpa.
Adapting the recipe to your taste
You can adjust the basic plokkfiskur recipe entirely to your own liking. Add vegetables such as peas or carrots, for example, to raise the nutritional value and bring extra colour to the plate. Another option is to scatter a little cheese over the finished dish for a savoury crust, much as you would with Plokkfiskur with Melted Cheese. This lets you shape the dish creatively without losing its characteristic flavour.
Ingredient substitutions
If you do not have certain ingredients to hand, there are plenty of alternatives. Instead of cod you might use mackerel or even tuna. With the potatoes, you could try sweet potatoes for a sweeter result. Variations like these keep the recipe flexible and give you something new to discover each time you make it.
Drink pairing ideas
To complement the flavour of plokkfiskur, light drinks such as white wine or a pale lager work particularly well. They sit comfortably alongside the savoury aromas of the dish without overwhelming them. For an alcohol-free option, sparkling mineral water or a refreshing herb-and-citrus cooler does the job nicely. The right drink noticeably lifts the whole experience of this traditional meal.
Serving and presentation ideas
Presentation can add a great deal to your plokkfiskur. Serve the dish in individual bowls with a fresh sprig of parsley on top as a garnish. A table laid with natural materials — wooden coasters, linen napkins — creates a cosy atmosphere. A thoughtful presentation like this appeals to the eye and sharpens the appetite at the same time. A slice of Rúgbrauð on the side is a classic finishing touch.
A bit of history
Plokkfiskur has a long history in Icelandic cooking and has established itself as everyday home cooking in households across the country. Generation after generation of families has kept the dish alive and passed it on. Its origins reach back to the time of the first settlers, when fish and potatoes became the most readily available staples. Today plokkfiskur is a symbol of Icelandic tradition and of the country’s close bond with nature and the sea — one of the cornerstones of Icelandic cuisine.
