Ingredients & Prep

Ingredients: 1 kg potatoes (peeled, cut into even chunks), 200 ml milk (warmed), 1 medium onion (thinly sliced), 2 tbsp olive oil, salt and pepper to taste. Prep time: 10 minutes. Warm the milk while potatoes boil and slice the onion thinly.

Cooking Method

1) Boil potatoes in salted water for 15–20 minutes until tender. 2) While potatoes cook, heat olive oil in a pan over medium and gently sauté onions until soft and lightly golden (6–8 minutes). 3) Drain potatoes, return to pan, mash briefly. 4) Stir in warm milk a little at a time until you reach desired creaminess. 5) Fold in sautéed onions, season with salt and pepper, and serve hot.

Tips, Variations & Serving

Tip: For extra silky mash, mash potatoes through a ricer. Variation: swap milk for plant milk or stock for dairy-free; use butter or cream for richness. Serve with roasted meats, grilled vegetables, or as a hearty side.

FAQs

Can I use butter instead of olive oil? Yes—use the same amount (2 tbsp) for a richer flavor; melt it before tossing the onions.
Can I make this dairy-free? Replace milk with a plant-based milk (unsweetened) or use vegetable stock for a lighter dairy-free mash.
How do I store and reheat leftovers? Refrigerate up to 3 days in an airtight container; reheat gently on low with a splash of milk to restore creaminess.
