Ingredients

Use 1 kg potatoes (peeled, chunked), 200 ml warm milk, 2 tbsp olive oil, 1 medium onion (thinly sliced), salt and pepper to taste.

Method

Cover potato chunks with cold salted water, boil then simmer 15–20 min until very tender. While they cook, sauté sliced onion in olive oil until soft and lightly golden.

Tips & Variations

For richer mash use butter instead of some oil. Add roasted garlic, chives, or grated cheese for flavor. Use a ricer for ultra-smooth texture or a masher for a rustic finish.
