  • 2 pounds red potatoes scrubbed and cut into cubes
  • ¾ cup vegetable broth
  • 1 shallot chopped, can sub a sweet onion
  • 1 teaspoon garlic powder
  • ½ cup sour cream more for serving
  • ½ teaspoon salt
  • ½ teaspoon pepper
  • 3 to 4 cups baby arugula more to taste
  • 3 tablespoon chives chopped, more to taste


  • Combine the potatoes, broth, chopped shallots, and garlic powder in a slow cooker. Cook on high for 3 to 4 hours or low for 6 to 7 hours. 
  • When the potatoes are cooked and tender, change the heat setting to warm and add the sour cream, salt, and pepper. Use a potato masher or hand mixer to blend the potatoes. Add some extra broth to promote smoothness if desired.
  • When the potatoes are blended, stir in the arugula, and chives. Taste, adjust seasonings as needed, and mix in butter or more sour cream if desired. Enjoy warm! 


  • To make vegan, skip the sour cream or use a vegan butter substitute.
  • I prefer to leave the skin on my potatoes, but you can peel them if you don't like chunks of skin.
  • You can make these up to one day in advance and store in the fridge. To reheat, put them back in the crockpot on low for 1 or more hours. You can also transfer them to a baking dish, cover with foil, and reheat for 30-45 minutes at 350 degrees F. Mix in butter, sour cream, or milk as needed to keep them moist.
