Potato Salad with Pumpkin Seed Oil

Ask in an Austrian kitchen what belongs in potato salad, and the answer is often vinegar, stock and oil — never mayonnaise. In Styria that oil is pumpkin seed oil, poured cold at the very end over potatoes that are still warm. The roast aroma sits on top instead of vanishing into a creamy base.

The result is lighter than mayonnaise-bound versions, sharper on the tongue, and meant to be eaten warm — closer to a dressed vegetable dish than to what many people picture when they hear “potato salad.”

No mayonnaise, a clear bite

Some potato salads fill you up before the side has done its job. Here the texture stays open: the slices take up stock and vinegar, and the oil arrives only after. Anyone tasting Styrian oil this way for the first time notices how loudly it speaks beside mild acidity — and how little cream the dish needs.

Peel while the heat still stings

Waxy potatoes cook unpeeled in salted water until just soft — about 20 to 25 minutes, depending on size. Drain, then peel while they are still hot. The heat is not a footnote: cool potatoes soak up the stock poorly, and the salad stays flat.

Potatoes, stock and the bottle ready

While the tubers are still hot, stock, mild vinegar and mustard should already be waiting — and the dark bottle stands capped beside them. The potatoes go straight into a wide bowl so as little warmth as possible is lost. Hot stock-and-vinegar first, then a short rest. The oil comes later — not before, and not into the cooking pot.

Ingredients

Serves four.

• 800 g waxy potatoes
• 200 ml hot vegetable or light meat stock
• 3–4 tablespoons mild vinegar (apple cider or mild white wine vinegar)
• ½ small red onion, very finely diced
• 1 teaspoon mild mustard
• Salt and freshly ground black pepper
• A small handful of chives, chopped
• 3–4 tablespoons pumpkin seed oil, added only at the end

Apple cider vinegar sits closest to the Styrian original; a mild white wine vinegar works just as well. That last amount is deliberately generous: in this dish the oil is a main ingredient, not a garnish.

Method

1. Cook the potatoes. Boil the potatoes unpeeled in salted water until just soft — about 20 to 25 minutes, depending on size. Drain and peel while still hot, even if the fingers protest.
2. Slice and dress. Cut or dice the potatoes straight into a wide bowl so little heat is lost. Warm the stock if it has cooled, stir in vinegar and mustard, and pour the mixture evenly over the still-hot potatoes.
3. Turn gently. Fold the potatoes carefully rather than stirring hard, so the slices take up liquid without falling apart. Leave the bowl for 10 to 15 minutes — in that time the potatoes absorb most of the liquid.
4. Season and taste. Add the onion, season with salt and pepper, and taste — at this stage the salad should taste clearly of vinegar, because the oil that follows softens that sharpness rather than amplifying it.
5. Add the oil. Pour the pumpkin seed oil last over the still-warm salad and fold it in gently. Because it arrives away from heat and only after the vinegar, no aroma is lost to steam.
6. Finish and serve. Scatter the chopped chives and serve warm or at room temperature.

When the dark oil runs over warm potatoes

This is the moment: the salad still smells of vinegar and stock, the slices are soft and warm. Pumpkin seed oil settles over them — glossy, nutty, without frying. Fold, do not beat, so the pieces hold. Unsure whether the bottle is truly roasted and clearly labelled? How to check pumpkin seed oil quality helps. The wider story opens under Discover.

Serve warm, refresh leftovers gently

Fridge cold dulls vinegar and oil alike — so eat warm or at room temperature. The salad sits well beside grilled sausage, pan-fried fish or a soft-boiled egg, and alone with good bread just as well. Leftovers keep for a day; bring them back to room temperature and add a small extra pour of oil before serving. More everyday ideas live under Kitchen.
