What Type of Potatoes to Use

The type you use will depend on the texture you are going for. Russet potatoes are really starchy and they are fluffy. Yukon gold potatoes have smooth, waxy flesh, that is also moist. Red potatoes are similar to Yukon and are really creamy. If you want super smooth potatoes you can use Yukon gold or red potatoes.

How to Season the Potatoes

Potatoes are bland on their own. Spices and salt are a must. I love to use garlic powder, onion powder, salt, and pepper.

Other spices I love to add from time to time are smoked paprika, Cajun Seasoning, or Creole seasoning for extra flavor and a twist.

How to Get the Potatoes Creamy

Buttermilk and sour cream (or plain Greek yogurt) will make these potatoes super creamy, especially if you use gold potatoes. Buttermilk has lactic acid that will result in creamy and fluffy mashed potatoes. It’s a game-changing ingredient.

Do You Leave the Skin on the Potatoes

This is up to you. The skin has lots of nutrients, so it’s beneficial. You can remove the skin if you wish.

Over-Boiling the Potatoes

When you boil the potatoes for too long it will result in potatoes that are overcooked and absorb a lot of liquid. When you go to mash them, they will be soupy. Instead of having fluffy mashed potatoes, you will have a watery blob. If you are cooking your potatoes on the stovetop, keep a watchful eye.

If using an Instant Pot or pressure cooker, be sure not to use too much liquid.

Freezer Tips

You can freeze these tightly sealed and they are best when used within a month. After that, they will start to get freezer burned and form ice crystals. Defrost overnight in the fridge.
