Caramelised Onion Mashed Potato

Fluffy mashed potato with a hint of caramelised onions.
Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes
Servings 4


  • 2 lbs potatoes, peeled and chopped into chunks
  • 1 onion, sliced thinly
  • 2/3 cup hot milk
  • 3-5 tbsp butter, we like buttery mash
  • salt and pepper to taste
  • Parsley to garnish, optional


  • Fill a large saucepan with water and lightly salt. Add in the potatoes and cook until tender, 20-25 minutes.
  • Whilst the potatoes are cooking, melt 3 tablespoons of butter in a frying pan/wok on a medium heat. Add in the sliced onions.
  • Cook the onions for about 20 minutes until soft and lovely and brown, stirring occasionally.
  • Once the potatoes are cooked drain and mash them. (We use a potato ricer and find it much easier!)
  • Heat the milk up for about 40 seconds and then place in a food processor with half of the onions. Blitz until smooth.
  • Pour into the pan you cooked the mash in.
  • Add in the mashed potatoes and stir. At this stage taste and then add in the extra 2 tablespoons of butter if required. Season to taste. Add in the remaining onions (I reserved some to garnish) and mix until combined.
  • Serve immediately and garnish with some parsley if you'd like.
