My grandmother's tangy potato recipe is a total game changer using only 4 ingredients.

This oven baked 4-ingredients Amish salt and vinegar potato recipe is my grandmother’s tangy potato dish that truly feels like a little kitchen miracle. It comes straight from the kind of farmhouse cooking where you work with what you have and let simple ingredients really shine. The potatoes soak up vinegar for that punchy, salt-and-vinegar flavor, then roast up golden and crisp on the outside while staying fluffy inside. It’s the kind of easy, no-fuss side dish that goes with just about any family dinner and always gets people reaching for seconds.

These potatoes are wonderful alongside roasted chicken, pork chops, or a simple grilled steak. They also pair nicely with meatloaf or baked fish for an easy weeknight meal. Add a green vegetable like steamed green beans, a tossed salad, or roasted broccoli to round things out. For a casual get-together, serve them right on the foil-lined baking sheet with small plates and toothpicks so everyone can grab crispy bites straight from the pan while they’re still hot.

Servings: 4

2 pounds russet or Yukon Gold potatoes, scrubbed and cut into 1-inch chunks

Preheat your oven to 425°F (220°C). Line a large baking sheet with aluminum foil for easy cleanup and to help the potatoes crisp up. Lightly grease the foil with a bit of oil so the potatoes don’t stick.

Place the potato chunks in a medium saucepan and pour in the white vinegar. Add enough water, if needed, just to barely cover the potatoes while keeping the vinegar flavor strong. Bring to a gentle boil over medium-high heat.

Once boiling, reduce the heat and simmer the potatoes for about 8–10 minutes, just until they are barely fork-tender on the edges but not falling apart. This helps them soak up the tangy flavor and roast up extra crispy.

Drain the potatoes very well in a colander, letting the steam escape for a minute or two so they dry slightly. The drier the potatoes, the crisper they’ll get in the oven.

Transfer the drained potatoes to a large bowl. Drizzle with the vegetable oil and sprinkle with the coarse sea salt. Toss gently but thoroughly so every piece is coated. If a few edges rough up and look a little fuzzy, that’s good—it helps create those extra crunchy bits.

Spread the potatoes out in a single, even layer on the foil-lined baking sheet. Make sure they have a bit of space between them so they roast instead of steam.

Bake in the preheated oven for 25–35 minutes, flipping the potatoes once halfway through cooking, until they are deep golden brown and crispy on the edges. Keep an eye on them toward the end so they don’t get too dark.

Remove the baking sheet from the oven. While the potatoes are still hot, taste one and sprinkle on a little more sea salt if needed. If your family loves extra tang, you can lightly splash a tablespoon or two of vinegar over the hot potatoes and toss gently right on the pan.

Serve the potatoes straight from the foil-lined baking sheet or transfer them to a warm serving dish. Enjoy them while they’re hot and crisp for the best texture.

For kids or picky eaters who aren’t sure about strong vinegar flavor, reduce the vinegar in the simmering step to 1/2 cup and make up the rest with water, then skip the extra splash at the end. If your family loves bold salt-and-vinegar flavor, let the potatoes sit in the hot vinegar for 5 extra minutes off the heat before draining, or add a bit more vinegar after roasting. You can swap in apple cider vinegar for a slightly sweeter tang that feels a bit more old-fashioned and farmhouse-style. If you need to make a big batch for a crowd, use two baking sheets and rotate them halfway through so everything browns evenly. For easier weeknights, cut the potatoes in the morning and keep them covered in cold water in the fridge, then drain and follow the recipe at dinnertime. Leftovers reheat nicely in a hot oven or air fryer to bring the crispiness back.
