Baked Potato Wedges in the Oven without Oil
Instructions
Separate the whites from the yolks. Whisk the egg white with a mixer or whisk until stiff peaks form – you want a dense, white foam, like for meringue. Keep the yolks for an omelette or another recipe. A fluffy foam creates a thicker protective layer and a crispier crust.
Cut the potatoes into thin wedges 5–7 mm thick, all the same thickness – this way they bake evenly. I leave the skin on: it contains plenty of vitamins and helps the wedges hold their shape. Season generously with salt and pepper, mixing with your hands.
Add spices to taste. I use a mix of curry and paprika – they give that characteristic yellow-orange "restaurant" colour. Rosemary, thyme, ground fenugreek, chilli or dried vegetables – tomatoes, peppers, onion, garlic – also work well. Feel free to experiment.
Add the whipped egg whites to the potatoes. Mix thoroughly with your hands so that every wedge is coated in a thin layer of egg white – this is the secret oil substitute. As it bakes, the egg white roasts into a lovely crust.
Place the potatoes in a non-stick baking dish – glass, silicone or clay. Spread them in a single layer so that every wedge heats from all sides. Bake in the oven for 30–35 minutes at 220 °C – the high temperature is needed to roast the crust. Turn the wedges over halfway through baking.
The oil-free oven-baked potato wedges are ready. The crust should be golden and crispy, and the centre soft. Arrange the side dish on a plate and serve immediately while hot – once cooled, the potatoes lose their crunch.
Tips
- 1
The egg white creates a crispy crust without oil – do not skip this step, otherwise the taste will be completely different.
- 2
Cut the wedges to an even thickness of 5–7 mm – this way they bake evenly and you won't end up with half-raw pieces.
- 3
Use a non-stick dish – the potatoes won't stick and there is no need to grease it with oil. I make oven-baked French fries on a similar principle.

Experiment with spices – curry gives an Indian accent, rosemary an Italian one, and dill a Russian one.
FAQ
Why is whipped egg white needed in this recipe? +
Egg white is the key ingredient for a crispy crust without oil. As it bakes, it forms a thin protective film on each wedge that roasts to a golden crust – the effect is similar to oil, but without the fat and calories. Without egg white the potatoes turn out "boiled", with no characteristic crunch. It must be whipped: liquid egg white won't give a dense coating. You can use aquafaba (chickpea cooking water) for a vegan version – it also whips into a foam and works in the same way.
At what temperature should the potatoes be baked? +
Around 220 °C for roughly 30–40 minutes, until golden brown. The high temperature is exactly what is needed to form the crispy crust – at 180 °C the potatoes simply cook through but without the characteristic crunch. The time depends on the thickness of the wedges: 5 mm – 25–30 minutes, 7–10 mm – 35–40 minutes. Check doneness with a fork – it should slide easily into a wedge. For extra browning, switch on the top heat or the grill setting for the last 3–5 minutes.
Can I add oil for richness? +
You can, but then the calorie count rises to about 110–130 kcal per 100 g and the dish loses its "diet" value. If calories aren't a concern, add 1 tablespoon of olive oil and the potatoes will be even more aromatic. The recipe is designed as a diet-friendly oil-free version from the start – that is its main feature. If you are making it for a family with no restrictions, I recommend the classic recipe with oil – the flavour will be richer, but the "without oil" point is lost.
