Creamy SauerKraut Gratin with Duck Confit

This creamy sauerkraut gratin with duck confit is a sophisticated take on Alsatian comfort food. The dish combines the signature tang of fermented cabbage with the rich, melt-in-the-mouth texture of slow-cooked duck. Infused with aromatic juniper berries and a hint of nutmeg, the savoury custard binds the ingredients into a golden, bubbling bake that is both indulgent and deeply satisfying.

As a high-protein main course, this gratin is an excellent choice for a warming weekend dinner or a celebratory winter meal. The addition of crispy duck skin as a garnish provides a delightful textural contrast to the silky cream base. Serve this homemade French-inspired classic alongside a simple green salad or some buttery steamed potatoes to balance the rich flavours.

How to make Creamy SauerKraut Gratin with Duck Confit

Preheat oven to 191°C with rack in middle.

Butter baking dish and coat with bread crumbs. Chill until ready to use.

Cook onion with bay leaf and juniper berries in butter in a 12-inch heavy skillet over medium heat, stirring occasionally, until well browned, 8 to 10 minutes. Add sauerkraut and cook, stirring occasionally, until heated through and liquid has evaporated, about 2 minutes. Discard bay leaf.

Meanwhile, remove skin and bones from duck legs, reserving skin and discarding bones. Tear meat into 1-inch pieces and stir into sauerkraut. Transfer to baking dish.

Whisk together cream, milk, eggs, nutmeg, 1/2 teaspoons salt, and 1/4 teaspoons pepper, then pour over sauerkraut. Bake until custard is set and edges are lightly browned, 45 to 50 minutes.

While custard bakes, thinly slice reserved skin, then season lightly with salt and pepper. Cook in a dry medium nonstick skillet over low heat, stirring to separate, until fat is rendered and skin is crisp, 6 to 8 minutes. Serve gratin with crisp skin scattered on top.
