  • 2 ¼ lbs. Russet potatoes peeled and cut into 2-inch chunks
  • 4 Tbsp. butter salted
  • 3-4 cups kale stems removed, coarsely chopped
  • ¼ cup green onions chopped
  • 2 cloves garlic finely minced
  • 1 cup milk regular or a non-dairy alternative
  • 2 tsp. salt divided


  • Add potatoes to a large pot or 5-6 quart Dutch oven. Cover the potatoes with at least 1 inch of water and add 1 teaspoon of salt. Bring everything to a boil. Boil for 15-20 minutes, or until the potatoes are fork tender, and then drain in a colander.
  • Melt the butter in the same pot over medium heat. Add the greens and cook for 3-4 minutes or until they begin to wilt and give off moisture. Stir in the chopped green onions and garlic and continue cooking for an additional minute.
  • Pour in the milk and scrape the bottom of the bottom to release any bits or pieces that might be stuck.
  • Add the and the additional teaspoon of salt. Use a potato masher or a large fork and mash the potatoes together, incorporating the greens as you do. Serve immediately with a sprinkle of finely chopped fresh parsley and enjoy!
