Boil peeled potatoes until tender, and soften chopped onion separately in a pan. Mash the potatoes while hot, then mix in the onion and enough milk, plant milk, or cooking water to reach the texture you want.
Frying the onion gives potato and onion mash a sweeter, more pronounced flavor. For a milder taste, boil finely chopped onion with the potatoes instead; drain well before mashing so the finished dish does not turn watery.
Floury potatoes are usually best for potato and onion mash because they break down easily and make a fluffy result. Waxy potatoes work too, but produce a firmer mash, so add any milk or cooking liquid gradually.
Use a potato masher or ricer rather than a blender or food processor. Overworking hot potatoes releases more starch and can make potato and onion mash sticky; drain them thoroughly and mash just until the onion is evenly mixed through.
Potato and onion mash pairs well with roasted vegetables, lentil patties, and dishes served with gravy or sauce. It also works as a topping for a vegetable bake; spread it over the filling and brown the top in the oven.
Yes, prepare potato and onion mash up to a day ahead and refrigerate it in a covered container. Reheat it gently in a saucepan before serving, stirring in a splash of milk or water if it has thickened.
Yes, you can freeze potato and onion mash in an airtight container, though thawing may make it slightly grainy or watery. Thaw it in the refrigerator, reheat thoroughly, and stir well to bring the texture back together.
Reheat potato and onion mash slowly in a covered pan over low heat, stirring occasionally. Add a little milk, plant milk, or water as needed. For microwave reheating, use short intervals and stir between them to heat it evenly.
Yes, potato and onion mash works without butter or milk. Mash the cooked potatoes with a little reserved cooking water or olive oil, adding it gradually until the mash is soft. Soften the onion with water or oil as well.
Yellow or brown onions give potato and onion mash a rounded, savory flavor and soften well when cooked. Red onions can be used for a sweeter result, while spring onions are best stirred in near the end for a fresher taste.

Potato and onion mash is a simple home-style side made by mashing cooked potatoes with softened onion. The onion adds a gentle savoury sweetness, while the potatoes give the dish its soft, comforting texture; it can be left slightly chunky or mashed until smooth. Versions of this pairing turn up in home cooking in many places, and it works alongside roasted or grilled foods, stews, and vegetable dishes. It is an easy way to make plain mashed potatoes more flavourful without relying on a rich sauce.
The dish is mainly a source of carbohydrates, and it also provides potassium and vitamin C. For a lighter result, soften the onion with little or no added fat and keep the mash simply seasoned. Pair it with vegetables or a protein-rich main for a more balanced plate.
