  • 3 pounds Yukon Gold potatoes cubed
  • 4 oz low-fat cream cheese softened
  • 4 oz low fat sour cream or Greek yogurt
  • 3 oz evaporated skim milk ½ of a small can
  • 1 small onion diced fine
  • Salt & pepper to taste
  • Milk & butter


  • Add potatoes to a large pot of water. Bring to a boil and cook until tender, about 15 minutes. Drain and mash.
  • In the meantime, sauté onion in a small skillet until onion is translucent. If you skip this step, the onions will be crunchy in your finished potatoes, and nobody wants crunchy potatoes.
  • In a medium bowl, combine cream cheese, sour cream, evaporated milk, cooked onion, salt, and pepper until blended. Add to mashed potatoes and mix well.
  • Transfer mashed potato mixture to the crock pot. We use a 6-quart crock pot, and the potatoes half fill it.
  • Can be cooked on low up to 4 hours. Re-moisten with milk and butter if needed.


Alternately, if you want to skip the boiling all together, you can add the potatoes to the slow cooker with plenty of water to cover them and cook on high for 4 hours or low for 8 hours. Drain and mash right in the crockpot, then proceed with step 2 as indicated above.
