How To Make Mashed Potatoes in a Crock-Pot

Use Your Crock-Pot to Make Real Mashed Potatoes While at Work

Instant mashed potatoes may be your go-to side dish for dinner after a long day at work, but they sure don't have the same comfort-food appeal as homemade mashed potatoes. With a little planning and your trusty Crock-Pot, you can cook tasty homemade mashed potatoes while you're slaying the day at work.

This simple recipe will conjure up memories of Thanksgiving meals.

Total Time: 5 to 6 hours | Prep Time: 30 minutes | Serves: 8 to 12


  • 5 pounds russet potatoes, washed and peeled
  • 1 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 1/4 cup unsalted butter
  • 3 cups milk, divided


  1. Using a sharp knife, cut the potatoes into 1-inch cubes and place in a 6- or 8-quart greased Crock-Pot.
  2. Add salt, pepper and 1 1/2 cups of milk to the potato mixture and stir.
  3. Plug in your Crock-Pot, set it to high and cook for 4 to 5 hours. Then turn the setting to warm until you're ready to mash.
  4. In a small saucepan, gently warm 1 1/2 cups of milk over low heat and pour over the potato mixture in the Crock-Pot.
  5. With a potato masher or electric mixer set to low speed, blend the potatoes until creamy. Do not over mix.
  6. Keep your mashed potatoes in the Crock-Pot set to warm until you're ready to serve.
  • A programmable Crock-Pot may be helpful if you have an especially long day at work or a busy after-school schedule. 
  • If you're looking to save calories, replace the milk added to the Crock-Pot before cooking with vegetable or chicken broth. Add flavor to your potatoes with onion or garlic powder when mashing. Or, for a little kick, consider Cajun spice.
