Ingredients

  • 3 pounds red potatoes
  • 24 oz vegetable broth
  • 3 tbsp butter
  • 4 garlic cloves
  • 1/4 cup milk
  • 1/4 cup vegetable broth reserved
  • 1/2 tsp salt
  • 1 tsp black pepper

Method

  1. Peel the potatoes and cut into large chunks.
  2. Place in a slow cooker and pour the broth over the potatoes.
  3. Cook on high for 4 hours, stirring occasionally.
  4. Drain the potatoes over a large bowl and save the broth.
  5. Put the potatoes back into the slow cooker and add the butter and the 1/4 cup reserved vegetable broth.
  6. For a smoother consistency, mix with an electric hand mixer until smooth then add the milk, salt and pepper and mix again. For a chunkier texture, use a hand masher to mash until desired consistency, then add milk, salt, pepper. If dry, add 1-2 Tbsp more milk or broth.
  7. When ready to serve - stir and if it seems like it has thickened add some more of the reserved broth and mix well.
