How to make The Best Mashed Potatoes-

  • Boil mashed potatoes – don’t forget the salt!. Drain water.
  • Prepare milk/sour cream/butter mixture – you want it to be warm.
  • Mash potatoes!
  • Add milk mixture.
  • Cream potatoes.
  • Enjoy, friends!

TIP:   Be sure to mash the potatoes until creamy before adding the milk mixture. If you don’t mash the potatoes enough and add the milk, you’re more likely to have lumps.

NOTE:  Lumps in the mashed potatoes are a sign of undercooked potatoes.

How to cook potatoes-

  • Add your potatoes to a saucepan, cover them with about 1” water.
  • Salt the potatoes. By adding salt, it really brings out the flavors of the potatoes.
  • Bring potatoes to a soft boil and cook until the potatoes are easily pierced with a knife.
  • Drain water and mash potatoes.

How to mash potatoes-

How to mash the potatoes is a personal preference, I’d say. Some people only use a potato masher and will not switch to anything else. I prefer a hand mixer. It’s easy, quick and the consistency is wonderful – no chunky pieces.

Are mashed potatoes best with skin-on or peeled?

We like both! Depends on what you are going to serve the potatoes with. You can either peel the potatoes or keep the skin on and continue with the recipe!

I even like to keep the skin-on in some of my soups, like THIS one.

What kind of potatoes should I use for mashed potatoes?

Though you can use Russets and Idaho potatoes for mashed potatoes, with their high starch and low water content, the potatoes aren’t as creamy as thin-skinned Yukon gold potatoes.

If using Russet or Idaho potatoes use more milk. (For this recipe, use ¾ cup milk instead of 2/3 cup).

What can I add to mashed potatoes for flavor?

You can add different ingredients to up the taste of creamy mashed potatoes. Try:

  • Minced garlic (add to the saucepan when cooking the potatoes).
  • Cheese (Add your favorite cheese when adding the butter/milk mixture to the mashed potatoes. Four cheese, Mozzarella, Mexican, or grated Parmesan are all great options.)
  • Herbs- your favorite herbs
  • Top with bacon bits as you would a loaded potato.
  • Top with cheese and green onion or chives.

      You could definitely serve the chicken stroganoff over the mashed potatoes instead of the pasta. Hope you love it.
