Prep Time10 mins
Cook Time30 mins
Total Time40 mins


  • 8-10 medium size russet potatoes, peeled and cut into 3/4 inch cubes
  • 1 medium onion, diced
  • water to cover
  • 1/4 cup butter or margarine
  • 4 cups milk
  • 2 cups heavy cream
  • 1 Tbsp salt
  • 1/2 tsp black pepper
  • 1-2 cups mashed potato flakes , to thicken


  • Add potatoes and onions to a stock pot. Cover with water to slightly above the top of the vegetables.
  • Bring to a boil. Reduce heat to medium and simmer until potatoes and onions are tender, about 20-30 minutes.
  • Add butter or margarine.
  • Slowly add milk, stirring constantly. If you add the milk too quickly, it could curdle and cause little milk lumps in the soup. This won’t affect the flavor, but it doesn’t look particularly appetizing.
  • Add cream to soup once milk has been fully incorporated.
  • Season to taste with salt and pepper. I like my soup relatively salty, but I added enough to flavor the soup while still leaving room for people to add more if they wish.
  • Finally, stir in potato flakes a handful at a time, waiting a minute or so between handfuls to be sure you don’t over-thicken the soup. Once the soup is as thick as you like it, you don’t need to add any more potato flakes. If you happen to over-thicken, just add a bit more milk.


Turn this recipe into loaded baked potato soup by adding toppings at the table. You can have bacon, sour cream, green onions and shredded cheddar cheese available so people can customize their soup to their liking.
