Few dishes nail the balance of crispy exterior and tender, yielding interior quite like this classic Swiss potato cake. The magic comes from a clever two-step process — parboiling the potatoes first, then chilling them overnight — which draws out excess moisture and gives the finished rösti that signature shatteringly golden crust. Every ingredient here is straightforward and plant-forward, with just a touch of butter and neutral oil to build richness and help the crust develop without any dairy-heavy additions that could cause issues. That small amount of butter is well within what many people managing lactose sensitivity handle comfortably, and the overall dish is about as far from a cream-laden potato gratin as you can get. The flip is the dramatic moment — inverting the whole golden cake onto a plate before sliding it back into the pan — and it is genuinely satisfying to pull off. Serve it cut into wedges straight from the board while it is still crackling hot, and it works beautifully as a hearty side or a centerpiece all on its own.

Ingredients

4 servings

2 lbs (about 4 medium) yukon gold or russet potatoes
1 tsp kosher salt, plus more to taste
¼ tsp freshly ground black pepper
2 tbsp unsalted butter, divided
2 tbsp neutral oil (such as canola or sunflower oil), divided

Instructions

1
Place the whole, unpeeled potatoes in a large pot and cover with cold water by at least 1 inch. Bring to a boil over high heat, then reduce to a steady simmer and cook until a skewer meets firm resistance about 1 inch in from the surface but the center is still raw, about 12–15 minutes — the potatoes should be about halfway cooked through. Drain and let cool completely, then refrigerate uncovered for at least 8 hours or overnight.
2
Peel the cold parboiled potatoes. Using the large holes of a box grater or a food processor fitted with a grating disc, grate the potatoes into a large bowl. Season with 1 tsp salt and 1/4 tsp black pepper and toss gently to distribute.
