Recipe Variations

  • Fried egg: Serve champ for breakfast with a fried egg on top.
  • Hot champ: Add white pepper or cayenne pepper when making Irish champ to make it spicy.
  • No green onions: The first Irish champ was made with stinging nettles but has since been replaced with scallions or green onions. But you can try both.
  • Herbs and spices: Add other herbs and spices such as rosemary, thyme, oregano, onion powder, and basil. Sweet paprika would also add a lovely flavor.
  • Grass-fed butter: For less trans-fat and saturated fat, use grass-fed butter.
  • Sweet mashed potatoes: Make this a sweeter dish by using sweet potatoes instead of russets.

How to Store Leftovers

You can store leftover Irish champ in an airtight container in the fridge for up to five days.

You can also freeze Irish Champ mashed potatoes in a freezer bag for up to four months. For best results, thaw overnight in the fridge before reheating.

To reheat, add a bit more milk and green onions for extra flavor and creamy mashed potatoes.

Recipe Tips

  • Chop green onions roughly so you get the most flavor in your Irish mashed potatoes.
  • Add potatoes to cold water before boiling. Then, turn to low heat and simmer until potatoes are fork tender.
  • Green onion is an essential ingredient. Use one bunch green onions for the most traditional Irish dish.
  • For extra creamy mashed potato mixture, use an electric mixer on low speed to combine after using a potato masher or ricer.

What kind of potatoes are best for Irish Champ?

Choose a type of floury potato with a high starch/low water content like Yukon Gold or Russets. Floury potatoes are the kind that turn thick and fluffy when mashing because have a dry, delicate texture. In Ireland, they would be called King Edward, Maris Piper, or Emerald Isle potatoes. It is best not to use waxy potatoes because they do not get as fluffy.

Why do they call these mashed potatoes Irish Champ?

Traditional Irish champ was originally made to help prevent malnutrition for the Irish who were suffering under British rule and could not afford much food. Irish mashed potatoes are a good source of vitamin C. Some also say it is because the word champ means mashed or pounded in Irish. Whatever the reason for the name, it is still popular in Northern Ireland and Irish communities all over the world.

Do I have to peel my potatoes?

Some of the best Irish recipe champ dishes use unpeeled potatoes. Just make sure you scrub them well before cooking and then mash the cooked potatoes with a potato masher or mixer with the potato skins on. This gives our traditional Irish champ an absolutely delicious flavor and texture for a side dish or with corned beef for a hearty meal.
