  • 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


  1. 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.
  2. 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.
  3. Pour in the milk and scrape the bottom of the bottom to release any bits or pieces that might be stuck.
  4. 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!
