New potatoes, carrots and deeply caramelized onions baked together with cream — a festive Swedish side for midsummer and holiday tables.
This bake draws on Sweden's love of new potatoes (färskpotatis) and caramelized onion, ingredients that show up constantly at Midsummer celebrations, when the year's first tender new potatoes are harvested and treated almost ceremonially. Carrots and new potatoes are par-cooked before baking with a generous amount of onion that's been cooked low and slow until deeply golden and sweet, then finished with a light cream sauce that binds everything together without masking the vegetables' own flavor. The caramelized onion is the heart of the dish and deserves the full 25-30 minutes it needs over low heat — rushed onions taste sharp and one-dimensional rather than the deep sweetness that makes this bake worth the effort. New potatoes, prized in Sweden specifically for their thin, delicate skins and sweet flesh, need only a light scrub rather than peeling, keeping more of their flavor and nutrients intact. It's a side dish built for the long, light evenings of Swedish summer celebrations, though it works just as well as an autumn or winter comfort side alongside roasted meats.
Serves 6
Melt 2 tbsp butter in a wide pan over low heat. Add onions and brown sugar, cook slowly for 25-30 minutes, stirring occasionally, until deep golden and sweet.
Keep the heat low throughout — rushed onions taste sharp instead of developing real sweetness.
Boil potatoes and carrots in salted water for 8-10 minutes until just starting to soften. Drain.
Butter a baking dish. Combine the par-cooked vegetables and caramelized onions, spreading evenly.
Whisk cream, stock, salt and pepper together and pour over the vegetables.
Dot with remaining butter and bake at 190°C (375°F) for 30-35 minutes until bubbling and the vegetables are fully tender.
Scatter with fresh dill and serve hot as a side to roast meats or fish.
Use genuinely fresh, thin-skinned new potatoes when in season — their delicate skins and sweet flesh are worth seeking out rather than substituting mature storage potatoes.
Don't rush the caramelized onions; they're the flavor backbone of the whole dish and need the full slow cooking time.
Scrub new potatoes rather than peeling them to keep more of their delicate flavor and texture.
Add parsnips alongside the carrots for extra sweetness and variety.
Swap heavy cream for crème fraîche for a slightly tangier finish.
Add crumbled bacon on top before the final bake for a heartier version.
Refrigerate up to 4 days. Reheat covered in a 160°C oven until warmed through; the cream sauce may need a splash of milk stirred in to loosen it back up.
New potatoes hold a near-ceremonial place in Swedish food culture, celebrated every Midsummer (Midsommar) alongside pickled herring and schnapps as one of the year's most anticipated seasonal foods. Caramelized onion is a similarly beloved staple across Swedish home cooking, valued for the way slow cooking transforms an everyday pantry vegetable into something genuinely worth building a dish around.
New potatoes are harvested early in the season before their skins fully mature, giving them a thinner skin and sweeter, more delicate flesh than mature storage potatoes — they're specifically prized in Sweden for this brief seasonal window.
Yes — assemble it fully a day ahead and refrigerate unbaked, then bake straight from the fridge, adding about 10 extra minutes to the covered baking time.
This almost always comes from cooking them over heat that's too high — proper caramelization requires low, patient heat over at least 25 minutes, not a quick high-heat sauté.
