What is Potato and onion mash?

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.
