TIPS

Here are a few tips that you can use to make sure that your no drain mashed potatoes turn out perfectly every time that you make them.

  • You could also add some other seasonings to your potatoes for more flavor, some of my favorites are bacon bits, green onions, chives, fresh herbs, shredded cheese, or minced garlic cloves.
  • Instead of sour cream, you could also add four ounces of softened cream cheese to add a very thick texture to this potatoes recipe,
  • My family enjoys the flavor of chicken broth in these potatoes, but water will work just as well.
  • Instead of sour cream you could also use plain greek yogurt for a creamy taste with lighter calories.
  • If your potatoes are too thick you can add a bit more liquid, for instance milk or half and half.
  • Russet potatoes are best for this recipe, but you could also use yukon gold potatoes or red potatoes. If you are using yukon gold you may want to reduce the amount of butter that you add because gold potatoes already have a buttery flavor to them.
  • If you don’t have a potato masher, or hand mixer you could also use an immersion blender to cream the potatoes.

HOW TO STORE

Leftover mashed potatoes can be stored in an airtight container in the refrigerator for up to three days.

To reheat, simply place the potatoes into a pot and warm over medium heat stirring occasionally until heated through. You may need to add a little bit of heavy cream or milk to help them become creamy again.

Or, you can also microwave leftover potatoes for about 1-2 minutes until heated through.

You can even freeze mashed potatoes for up to three months, just make sure to let them cool completely before placing into an airtight container and freezing. When you are ready to use, thaw overnight in the refrigerator and then heat on stovetop or microwave as directed.
