Traditional baked potatoes in ash are a rustic snack from Polish regional cuisine – originating from rural customs where potatoes were baked directly in the embers of a fire. The skin becomes charred and aromatic, the interior soft and creamy, and a simple treatment with olive oil, garlic, and fresh thyme gives the dish a distinct herbal note. They can be served as a standalone snack by the fire, with smoked meat, mushroom stew, or with sour cream as a dip. The dish is visually striking (black, cracking skins with green accents of thyme) and has an intense flavor – smoky, sweet-potato-like, and herbal.
Prepare a campfire or grill with a charcoal chamber. Light dry hardwood (beech, oak) and wait until a large amount of glowing embers and fine ash is formed – this usually takes 30–40 minutes. The goal is an even, long-lasting glow, not a large flame.
Use a fire pit or a grill with a lid; it's best to also have a shovel for ashes and heat-resistant gloves. Do not use softwood (resin gives an unpleasant taste).

Wash the potatoes under running water with a vegetable brush to remove the dirt. Dry each potato with a clean cloth. If the potatoes are very large, cut them in half so they bake evenly; standard portions: about 250 g of potato per person.
Use a vegetable brush and paper towel. The potatoes must be dry – a wet skin will smoke instead of roasting nicely.
3
Pierce the potatoes with a fork in 3–4 places (to allow steam to escape) and place them in a large bowl. In a separate container, mix the rapeseed oil with the crushed garlic and half of the chopped thyme leaves. Pour the mixture over the potatoes and thoroughly coat each potato with a thin layer of oil and garlic. Sprinkle evenly with salt.
Ingredients:
Rapeseed oil, Garlic, Thyme, Salt
Use a large bowl and a spoon or nitrile gloves for coating. Piercing prevents the potatoes from bursting during baking.
Baking in Ashes
4
When the embers are evenly distributed and covered with a thin layer of white ash, use a shovel to push some of the ash aside, creating a flat spot. Place the potatoes directly on the embers (skin side up) and lightly cover them with a thin layer of ash – do not bury them too deeply; they should be in contact with the embers. Bake for about 30–35 minutes, turning each potato individually every 10–12 minutes for even cooking.
Ingredients:
Thyme, Salt
Use long tongs or a spatula and fire gloves. Do not place your hands over the glowing ashes. The ashes should not be wet or too thick – a layer of 1–2 cm is sufficient.
5
Check the doneness by inserting a long metal skewer or knife into the largest potato – it should go in smoothly, and the center should be soft and hot (internal temperature around 95°C). If needed, bake for another 5–10 minutes. If you're concerned about ash on the skin, gently brush off the outer layer of ash just before removing.
Use a metal skewer or a kitchen knife. If the skin is very burnt, you can cut off the top and squeeze out the flesh like a "baked potato" or peel the skin thinly.
Serving
6
Remove the potatoes from the ashes with tongs onto a plate or board. Clean them with a dry brush or shake off the excess ash. Cut each potato in a cross (not all the way through), gently open them up, and season with freshly ground pepper, sprinkling the remaining thyme on top. Serve with a bowl of sour cream sprinkled with chopped parsley.
Ingredients:
Black pepper, Thyme, sour cream, Parsley
Use a cutting board and a long knife. If the potatoes are very hot, wait 2–3 minutes before cutting to make it easier and to prevent hot juice from flowing out.
Alternative (bake in the oven)
7
If you don't have the option to bake in ashes, preheat the oven to 220°C (top and bottom heating mode). Arrange the potatoes on a baking sheet lined with parchment paper and bake for 45–55 minutes (depending on size), until the skin is browned and the inside is soft. Halfway through baking, turn the potatoes and brush them with garlic oil.
Ingredients:
Rapeseed oil, Garlic
Use the largest baking tray possible and convection if available. Baking in the oven takes longer than in ash, but the flavor result will still be very good.
Fun Fact
💡
Baked potatoes in ash is an old rural technique; in 19th century Poland, housewives often buried potatoes in the embers of the oven or fire to prepare a quick and hearty meal for those working in the fields.
Serve the potatoes hot, straight from the grill. You can also add herb butter or cottage cheese with chives. For a "rustic" effect, do not peel the skin completely — a slightly cracked, roasted skin is a characteristic feature of the dish.
🥡Storage
Baked potatoes are best consumed immediately. Store in the refrigerator for up to 2 days in an airtight container. To reheat, use the oven at 180°C for 10–15 minutes to regain the crispiness of the skin; in the microwave, they will become rubbery.
