  • 2 ½ pounds root vegetables, Note 1
  • 3 tablespoon butter (or 4 for extra richness)
  • ¼ cup milk or cream (plus extra if needed)
  • salt and pepper to taste
  • optional: 2 green onions chopped
  • optional: 2-3 cups roughly chopped baby spinach


  • CUT ROOT VEGETABLES into roughly the same size - about 1 - 1 ½ inches. If using carrots, slice them thinner as they take longer to cook.
  • BOIL VEGETABLES: Place vegetables in a medium-large pot. Add enough water to cover veggies by 1 inch (2.5 cm). Add 2-3 teaspoon salt. Bring to boil. Lower to medium and gently boil for 15-18 minutes or until soft and easily pierced with a fork. Drain vegetables in a colander and return to the pot.
  • DRY AND MASH: On medium heat, shake cooked vegetables to dry them out for 1 minute. Add spinach and green onions if using as well as butter and milk/cream. Mash with a fork to get the consistency you like. Do not use a food processor or immersion blender to mash veggies. Taste and add salt and pepper as needed. Serve.


  1. Root Vegetables - Use two or more – white potatoes (I like Yukon/yellow potatoes best), sweet potatoes, carrots, parsnips, turnips, rutabaga (swede), celery root (celeriac).  Not a root vegetable, but you can also try pumpkin or butternut squash.
  2. Portions: Figure about ½ – ¾ cup (125-250g) root vegetable mash per person. You will need about 1 pound (0.45kg) root vegetables to make 2 cups mash or 3-4 servings.
  3. Make Ahead: To keep the mashed vegetables warm:
    • Make them an hour ahead and keep them in the pot on a warming ring, covered, on your stove (if you have one) for an hour.
    • Or put the bowl of mash, covered, over a pot of simmering water.
