My neighbor from church, Marlene, has been bringing these big crispy potato cakes to every potluck since the late 70s. I finally wore her down and she showed me how simple they really are: just potatoes, a little fat, and salt, baked up into one big golden rosti with lacy, crunchy edges. No fancy tools, no fussy ingredients—just the kind of practical, stick-to-your-ribs cooking that’s fed Midwestern families for generations.
This oven-baked version gives you that old-fashioned skillet flavor without standing at the stove flipping little pancakes, and it comes out looking mighty pretty on a platter too.
Serve this potato rosti hot, cut into wedges like a pie. It’s wonderful alongside eggs and bacon for a hearty breakfast, with a dollop of sour cream or applesauce if you’re feeling nostalgic. For supper, pair it with roast chicken, meatloaf, or a skillet of pork chops and some green beans or a simple salad.
Leftovers reheat well in a hot oven and make a fine base for a fried egg on top, or you can slice thin wedges and serve them as a snack with ranch dressing or ketchup for dipping.
Oven-Baked Potato Rosti
Servings: 4–6
Ingredients
2 pounds russet potatoes, peeled
4 tablespoons unsalted butter, melted (plus a little extra for the pan)
1 1/2 teaspoons kosher salt (or to taste)
Directions
Preheat your oven to 425°F (220°C). Place a heavy 10- to 12-inch oven-safe skillet or round metal baking pan in the oven to heat while you prepare the potatoes.
Peel the potatoes and grate them on the large holes of a box grater. Work quickly so they don’t discolor too much.
Place the shredded potatoes in a clean kitchen towel and squeeze firmly over the sink to remove as much liquid as you can. This step is Marlene’s big secret for getting those crisp, lacy edges.
In a large bowl, toss the squeezed potatoes with the melted butter and salt until everything is evenly coated.
Carefully remove the hot skillet or pan from the oven. Add a small dab of extra butter and swirl or brush it around to lightly coat the bottom and sides.
Spread the potato mixture into the hot pan, pressing it down firmly with the back of a spoon or spatula to make an even, compact layer. Pressing helps the potatoes stick together and brown nicely.
Bake on the middle rack for 25–30 minutes, until the top is lightly golden and the edges are starting to look crisp.
Carefully run a thin spatula around the edges to loosen the rosti. Place a large plate or platter over the pan and, using oven mitts, invert the pan so the rosti flips out onto the plate.
Slide the rosti back into the pan, browned side up now facing down, and return it to the oven for another 10–15 minutes, or until the second side is deep golden brown with crisp, lacy edges.
Remove from the oven and let the rosti rest for 5 minutes to set. Slide it onto a round white serving platter, cut into wedges, and serve hot.
Variations & Tips
You can swap in Yukon Gold potatoes for a slightly creamier center, though russets crisp the best. If you like a little onion flavor, grate in up to 1/4 of a small onion along with the potatoes, but keep in mind that extra moisture can make it a bit less crisp—just squeeze the mixture very well.
For a richer rosti, use half butter and half bacon drippings instead of all butter, which is how many church ladies did it back in the day. If you prefer individual cakes, mound small handfuls of the potato mixture onto a preheated, buttered sheet pan and flatten them into little rounds; they’ll bake a bit faster, so start checking at 15–20 minutes before flipping.
To keep the outside crisp, avoid covering leftovers while they’re still hot, or they’ll steam and soften; instead, cool them on a rack and reheat in a 400°F oven until sizzling again. For food safety, keep raw, peeled potatoes out of standing water at room temperature for long periods, and don’t leave the grated mixture sitting more than an hour before baking. Always handle the hot skillet and inverted plate carefully when flipping—use dry oven mitts and turn away from yourself so any steam escapes safely.
