parboil the potatoes the day before and grate them cold, so the shreds hold their shape and the starch crisps rather than turning to mush when you press the cake into the hot fat

The Method
Parboil aheadBoil the potatoes in their skins until just underdone, cool completely, then chill overnight so they firm up.
GratePeel and grate the cold potatoes on the coarse side of a box grater, season with salt, and toss loosely without packing.
Press and fryMelt butter and lard in a skillet, add the potato, press into an even cake, and fry over medium heat until the base is deep gold, about 12 minutes.
FlipSlide onto a plate, invert back into the pan, add a little more butter, and crisp the second side before serving.
Yes — this is exactly what an air fryer does well. Work in a single layer so the air can move, and shake or flip halfway for even crisping. It runs a touch faster than the oven, so check early.
Can you freeze Rösti? — Not ideal
You can, but the crisp coating softens. Freeze the cooked pieces, then re-crisp them in a hot oven or air fryer — never the microwave.
Can you make Rösti ahead of time? — Yes
Yes — it needs the chill time to set, so making it ahead is the whole point.
Is Rösti gluten-free? — Yes
Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.
Is Rösti vegan? — No
No — it contains meat, so it isn’t vegetarian or vegan.
