A creamy Danish potato casserole layered with mild curry powder, onion and cheese, baked until golden and bubbling.
Curry leaf itself isn't part of Danish cooking, but curry powder has a genuine and long-standing place in Danish kitchens thanks to old trade links with the former Danish West Indies and the popularity of karrysild (curried pickled herring) and karry-ret dishes brought home by Danish sailors. This casserole channels that same mild, sweet curry flavor into a classic kartoffelgratin, layering thinly sliced potatoes with a curry-spiked cream sauce and a blanket of cheese. The key to a gratin that holds together rather than turning watery is slicing the potatoes thin and even, about 3mm, so they cook through at the same rate as the sauce thickens. A roux-based bechamel gets its color and warmth from a spoonful of curry powder bloomed briefly in butter before the milk goes in, giving the whole dish a pale golden hue rather than the deep orange of an Indian curry. It's the kind of side dish that shows up at a Danish smorgasbord table alongside cold cuts and pickled herring.
Serves 6
Melt butter in a saucepan over medium heat and cook the onion 5 minutes until soft and translucent, without browning.
Stir in the flour and curry powder and cook 1 minute, stirring constantly, until it smells toasted and fragrant.
Whisk in the milk gradually to avoid lumps, then add the cream, salt and white pepper. Simmer 5 minutes, whisking, until thickened enough to coat the back of a spoon.
Preheat oven to 190C (375F). Layer the sliced potatoes in a buttered baking dish, pouring some curry sauce between each layer, finishing with sauce on top.
Cover with foil and bake 30 minutes, until the potatoes are nearly tender when pierced with a knife.
Remove the foil, scatter cheese over the top, and bake another 15-20 minutes until golden and bubbling and the potatoes are fully tender.
Rest 10 minutes before serving so the sauce sets slightly, then scatter with fresh chives.
Slice potatoes evenly with a mandoline so every layer cooks at the same rate.
Use a mild, sweet curry powder rather than a hot Madras blend — Danish curry dishes lean gentle, not fiery.
Let the gratin rest 10 minutes before cutting; it firms up and slices cleanly instead of sliding apart.
Add smoked ham: fold in 150g diced smoked ham between the potato layers for a heartier main course.
Fish-friendly: serve alongside pan-fried plaice or cod, echoing the classic pairing with karrysild.
Herb swap: use fresh dill instead of chives for a more traditional Danish finish.
Refrigerate leftovers covered up to 3 days. Reheat individual portions in a 180C oven for 15-20 minutes, or in the microwave, until hot through.
Curry powder entered Danish cuisine through trade with the former Danish colonies in the West Indies and through Danish sailors who brought spice blends home from Asian ports in the 19th and 20th centuries. It became firmly rooted in dishes like karrysild and karry-ret, mild curried preparations that remain common on Danish smorgasbord tables today.
A mild, sweet Madras-style or generic supermarket curry powder is closest to what Danish cooks traditionally use — it's meant to add warmth and color, not heat.
You can substitute a plant-based milk and cream, but the sauce will be noticeably thinner and less rich; add an extra tablespoon of flour to compensate for the lack of fat.
Potatoes release water as they cook, so slicing them too thick or skipping the roux-thickened sauce are the usual culprits. Keep slices thin and make sure the sauce is fully thickened before layering.
