  • 3 pounds Russet potatoes - peeled and cut into quarters
  • Water
  • 1 teaspoon salt
  • 1/4 cup butter
  • 1/4 cup sour cream
  • 2/3 cup half and half
  • 1 teaspoon House Seasoning Blend


  • Put prepared potatoes in the Instant Pot.
  • Pour enough water over the potatoes to just cover them.
  • Add salt.
  • Secure the lid and cook on high pressure for 10 minutes.
  • Quick release the pressure and test the potatoes for doneness - a fork inserted in the potato should easily release.
  • When potatoes are done, mash the potatoes to your desired consistency.
  • Stir in butter, half and half, sour cream and House Seasoning Blend.
  • You can add more half and half to reach your desired consistency.

Helpful Tips for All Recipes
  • When a recipe call for House Seasoning Blend, you can find the recipe on www.itisakeeper.com. Simply search for "House Seasoning Blend" or you can substitute salt and pepper to taste.  
  • I always use unsalted butter in my recipes.
  • I always use a meat thermometor to test for doneness when cooking meat.
  • When a recipe is made in the oven, it should be pre-heated to the temperature in the recipe, unless otherwise noted.
