Meal prep Tip

On a busy day, I will start this soup in the morning and allow it to do a full natural release. It will automatically switch to “keep warm”. Right before serving, I will blend the potatoes, add the heavy cream, and serve.

You can also meal prep the toppings by shredding the cheese ahead of time and cooking the bacon in the oven.

Pro Tips/Recipe Notes

  • You don’t have to peel the potatoes, but it will alter the appearance quite a bit if you don’t.
  • White and yellow onions are best, as red (c’mon, we all know they’re really purple) will give your creamy potato soup a pink hue.
  • If you don’t have an immersion blender, transfer the soup in batches to a blender. Remove the middle part of the blender’s lid and loosely place a towel over it. This will allow some of the steam to escape and not pop open the cover.
  • If doubling (6 or 8 quart only), the cooking time will remain the same. It will take longer to come up to pressure and depressurize. I recommend doing a full natural release if you are doubling this recipe. This prevents hot liquid from coming out of the vent during a quick release.

Notes

  1. Potatoes – I love a mixture of Russets and gold, but any peeled potatoes will be delicious.
  2. If you don’t have an immersion blender or hand mixer, transfer the soup in batches to a blender. Remove the middle part of the lid and place a towel over it. This will allow some steam to escape and not pop open the cover.
  3. White and yellow onions are best, as red will give your potato soup a pink hue.
