  • 3 lbs. russet potatoes $0.60
  • 1.5 cups chicken broth $0.18
  • 2 cloves garlic $0.16
  • Salt and freshly cracked pepper to taste $0.05
  • 4 oz. cream cheese $0.75
  • 1/2 cup milk $0.19
  • 1 Tbsp butter $0.11


  • Wash and peel the potatoes, then cut them into one-inch cubes. Mince two cloves of garlic. Add the potato cubes, minced garlic, chicken broth, and some freshly cracked pepper to the slow cooker. Stir briefly to distribute the garlic and pepper.
  • Place a lid on the slow cooker and cook on high for four hours or low for eight hours (for the Instant Pot, close the vent, choose the manual setting, and set the cook time to seven minutes. Once finished, use the quick pressure release method until the pressure normalizes).
  • Take the lid off the slow cooker and add the cream cheese, milk, and butter. Stir to combine the ingredients and mash the potatoes. For a smooth mashed potato, use a hand mixer to briefly blend the potatoes until smooth.
  • Taste the potatoes and add salt or pepper if needed.
