There is a particular rhythm to the Danish week, and Friday belongs to fish. It's not a rule anyone enforces, it's just how the kitchen turns. The fishmonger knows it, the supermarket knows it, and by late afternoon on a Friday you'll see people walking home with small paper parcels tucked under their arms. Inside, more often than not, a few fillets of plaice.
Fiskefilet med remoulade paa rugbrod is the sandwich those fillets are heading toward. A piece of plaice breaded and fried until the crust crackles, laid across a thick slice of dark rye, finished with a generous stripe of pale yellow remoulade, cool cucumber slices, and a squeeze of lemon. It sits somewhere between everyday food and small celebration, which is exactly where most of the best Danish cooking lives. Plaice, rodspaette in Danish, is caught in the shallow waters around the country, and though you can find it year-round, it's at its sweetest in early spring.
What matters most here is the crust. Three bowls, flour then egg then breadcrumbs, pressed firmly on both sides, and then fried in butter and oil until the outside is deep gold and the inside is still tender. Don't rush the butter. Wait until it foams and starts to smell like hazelnuts. That's the moment the fish goes in, and if you listen for the crackle when it hits the pan, you'll know you got the temperature right. Everything after that is assembly, and assembly is the easy part.
Plaice has been central to Danish coastal cuisine for centuries, pulled from the shallow waters around Jutland and the islands by small fishing boats that still work out of harbors like Thyboron and Hvide Sande. Fiskefilet as smorrebrod became a lunch restaurant staple in Copenhagen in the early 20th century, when the city's frokoststeder codified the pieces that define the tradition today. Remoulade itself is an adaptation of a French sauce, reinvented by Danish cooks into a sweeter, yellow-tinged condiment heavy with chopped pickles and a whisper of curry powder, and it has become so bound to Danish food culture that most Danes are surprised to learn it isn't Danish at all.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Three shallow bowls for breading
- •Heavy frying pan, 28cm
- •Mandoline or very sharp knife for the cucumber
- •Fish spatula or thin flexible turner
- •Serrated knife for the rugbrod
Instructions
- 1
Dry the fish
Lay the plaice fillets on a plate lined with kitchen paper and pat them completely dry on both sides. Wet fish and breadcrumbs do not get along. Any moisture left on the surface will turn the crust soggy in the pan, and the point of this dish is the crackle when your knife goes through. Season both sides lightly with salt and white pepper.
Plaice is a delicate fish. Handle the fillets gently so they stay whole. If one tears a little, don't worry. The breadcrumbs hide a great deal. - 2
Set up the breading
Line up three shallow bowls on the counter. Flour in the first, beaten eggs in the second, breadcrumbs in the third. The order matters. Flour dries the surface so the egg can cling. Egg is the glue. Breadcrumbs are the armor. Skip any one of them and the coating falls off in the pan.

Bread the fillets
Take one fillet at a time. Dredge it in the flour and shake off the excess, then dip it into the egg and let the extra drip back into the bowl, then press it firmly into the breadcrumbs on both sides. Press, don't sprinkle. You want the crumbs to stick in an even, generous layer. Lay each breaded fillet on a clean plate and let them rest for five minutes before frying. The rest lets the coating settle and stops it sliding off when it hits the butter.

Slice the cucumber
While the fillets rest, slice the cucumber as thinly as you possibly can. A mandoline is the right tool here. You want slices that are almost translucent, so they lay flat and cool against the warm fish. Thick rounds fight the sandwich. Thin slices belong to it.
- 5
Fry the fish
Heat the butter and oil together in a heavy frying pan over medium-high heat. Butter alone burns before the center cooks. Oil alone tastes of nothing. Together they give you the golden crust and the nutty richness you're after. When the butter stops foaming and starts to smell like hazelnuts, lay the fillets in carefully. Cook for two to three minutes on the first side without moving them. You'll know when it's right because the edges turn deep gold and the crust releases from the pan on its own. Flip once and cook for another minute and a half. Lift them onto kitchen paper to drain for thirty seconds.
Don't crowd the pan. If your pan is small, fry two fillets at a time. Too many at once drops the temperature of the butter and the crust goes pale and greasy instead of gold and crisp. - 6
Assemble the smorrebrod
Lay the slices of rugbrod on a board. Place a fried plaice fillet on each one, sitting squarely across the bread. If the fillet is longer than the bread, let it hang over the edge a little. That's part of the look. Now spoon a generous stripe of remoulade straight down the middle of the fish, from end to end. Not a dollop in the center. A stripe. This is the Danish way, and it matters because the remoulade is supposed to be a feature, not a condiment.
Use a teaspoon and the back of it to draw the remoulade into a clean line. A piping bag works too if you want the stripe perfectly even. The pros at the lunch restaurants in Copenhagen use a piping bag every time. - 7
Finish and serve
Overlap three or four cucumber slices along the stripe of remoulade, standing them on edge so they lean like fallen dominoes. Scatter a few dill fronds over the top and tuck a lemon wedge alongside the fish. Serve at once, with the lemon to squeeze over just before the first bite. Smorrebrod is eaten with a knife and fork, never picked up, and this one is particularly generous, so cut through all the layers in one clean slice. Tak for mad.
Chef Tips
- •Use plaice if you can find it. It's the traditional fish and its delicate, sweet flesh is what this sandwich was built around. If plaice isn't available, lemon sole or flounder work well. Avoid cod here. It's too thick and the proportions go wrong.
- •Danish remoulade is specific. It's pale yellow, slightly sweet, and full of finely chopped vegetables and a hint of curry. If you can't find a Danish jar, you can fake one by stirring mayonnaise with a little Dijon, chopped cornichons, chopped capers, a pinch of sugar, and the smallest touch of curry powder. It won't be the same, but it will be honest.
- •Good rugbrod matters enormously. This sandwich sits on the bread more than most, and a thin, bland loaf will collapse under the weight of the fish and the remoulade. You want a dense, dark, slightly sour rye that can hold its own.
- •A cold beer alongside is traditional, and a small glass of aquavit if the moment calls for it. Friday fish is one of the good moments.
Advance Preparation
- •The fish can be breaded up to an hour ahead and kept on a plate in the fridge, uncovered, so the coating stays dry. Bring back to room temperature for ten minutes before frying.
- •Fry and assemble just before serving. Cold breaded fish on cold bread is not this dish. The contrast between the warm, crisp plaice and the cool cucumber and remoulade is the whole point.
