  • Large saucepan
  • Potato masher


Horseradish Mashed Potatoes

  • 1 kg white potatoes Note 1
  • ½ tablespoon garlic powder
  • 1 tablespoon dried onion
  • 2 tbs horseradish cream Note 4
  • 50 grams butter
  • 1 tablespoon milk Note 2
  • salt to season
  • pepper to season
  • 2 tablespoon chives to garnish


Horseradish Mashed Potatoes

  • Fill a large saucepan ¾ with water and season with salt. Bring to the boil
  • Add your potatoes to the saucepan and boil for 30 mins
  • Once 30 mins is up test the potatoes with a skewer to ensure they are well cooked. If they are, turn the stove off and let them cool down in the hot water. If not fully cooked, try about 5-10 mins
  • Drain potatoes. Add dried onion, garlic powder, butter, milk, salt and pepper, stir to combine.
  • Add horseradish, starting with 1 teaspoon and building to 1 tablespoon. Taste, add up to 1 more tablespoon, tasting as you go.
  • Spoon into serving bowl, season with cracked pepper and garnish with chopped chives. Add a few little knobs of butter if desired.



  • Note 1 I use a brand called 'Aussie Baby White Potatoes' from Aldi. But you can use any potato you like including red potatoes. Try and use a starchy type variety. Sweet potatoes and brushed potatoes require different techniques than those of this recipe. 
  • Note 2 my saucepan that I boil potatoes in is 6 litres.
  • Note 3 I add approx a teaspoon of milk and gradually building to to a tablespoon. It is easy to mix in well and get a good consistency to taste. Add more if you prefer more moist to chunky mash.
  • Note 4 horseradish cream is a condiment found in the same section of the shops as mustard and spreads. It has a tang to it! It is not 'hot' but very unique in taste and texture.
