German-Style Fried Potatoes

This authentic German-style fried potato dish, often known as Bratkartoffeln, is a masterclass in texture and balance. By boiling the potatoes a day in advance and chilling them overnight, you ensure the cubes hold their shape in the frying pan, resulting in a satisfyingly crisp exterior and a fluffy centre. The addition of a sharp mustard vinaigrette and a splash of lager provides a sophisticated depth of flavour that cuts perfectly through the rich, golden crust.

As a versatile vegan side dish, these potatoes are ideal for a hearty weekend brunch or as a comforting accompaniment to a plant-based roast. The combination of sweet red onions and fresh chives adds a bright, savoury finish that makes this dish a guaranteed family favourite. For the best results, use a large non-stick frying pan to ensure every potato cube achieves that signature deep golden colour.

Ingredients for German-Style Fried Potatoes

  • 1.8kg unpeeled medium-size red-skinned potatoes

  • 70ml olive oil

  • 45ml malt vinegar or white wine vinegar

  • 1 tablespoon Dijon mustard

  • 90ml lard, rendered bacon fat, or olive oil, divided

How to make German-Style Fried Potatoes

Cook potatoes in large pot of boiling salted water until just tender when pierced with sharp knife, about 25 minutes. Drain. Refrigerate potatoes overnight.

Cut potatoes into 1/2-inch cubes (do not peel). Whisk oil, vinegar, and mustard in small bowl to blend for vinaigrette. Heat 45ml lard in each of 2 large nonstick skillets over medium-high heat. Add half of potatoes to each skillet; sprinkle with coarse salt. Sauté until potatoes begin to brown, stirring frequently, about 7 minutes. Add 3 tablespoons beer, then 200g red onions to potatoes in each skillet; cook until beer evaporates, stirring occasionally, about 1 minute. Reduce heat to medium and sauté until potatoes are brown around edges, about 5 minutes. Pour half of vinaigrette over potatoes in each skillet and toss to coat. Remove from heat. Season to taste with salt and pepper. Transfer all potatoes to large bowl. Sprinkle with chives.
