  • 1 Can of potatoes whole, sliced or diced
  • 1 cup water
  • 2 Tbs butter
  • ¼ tsp garlic powder
  • ¼ tsp onion powder
  • ¼ cup Grated parmesan cheese
  • ¼ Cup sour cream
  • ¼-½ cup milk using milk depends on how thick or thin you like your potatoes, see notes
  • Salt and Pepper to taste Make sure to taste first!


  • Drain the canned potatoes well.
  • In a medium saucepan over medium heat add the water and the can of potatoes.
  • Heat the potatoes until the water is bubbling and keep heating till the potatoes are heated through. Turn the heat off.
  • Drain the potatoes again.
  • Set the pot back on the hot stovetop and place the butter, garlic and onion powder, parmesan cheese and sour cream into the potatoes. Mash well with a potato masher OR whip with a kitchen mixer.
  • Once mixed, if too thick, add the milk SLOWLY. Start with ¼ cup and then add by tablespoon fulls until desired consistency is reached.
  • Taste and add salt and pepper.



You will want to drain the potatoes because the water in the potatoes doesn’t taste that great.
Drain the potatoes a second time because the water you added was simply for heating the potatoes up. You won’t need it in the recipe.
If you do not have some of the ingredients, it is ok. As long as you have butter, milk, salt and pepper, you will be fine. Just leave the other ingredients out.
You may need to add more milk than is stated if you don’t have sour cream.
It is fine to substitute greek yogurt for the sour cream . Other cheese tastes good too, but I really recommend the parmesan. The kind in the green can is fine.
Try to use whole milk if you have it. Other milks just aren’t stout enough. It is fine to substitute evaporated milk directly for the milk in this recipe. You can also substitute heavy cream but you may need to use a little more than what is called for.
Canned potatoes and parmesan cheese are both salty so you may not need to add any salt. But DO add the pepper.
