Recipe Tips

  • Add whole garlic cloves to the cut potatoes as they cook. Mash potatoes and garlic together for garlic mashed potatoes.
  • Store buttermilk mashed potatoes within two hours of cooking them to avoid any bacteria growth.
  • Don’t add your liquid all at once – Your potatoes won’t be able to soak up all the liquid in one go and if you try to force them to you will end up with wet mashed potatoes. Add your liquid in small increments and thank me later.

Can I use milk instead of buttermilk?

Yep just know that the tang from the buttermilk won’t be there. If you don’t have any, make your own by adding 1 tablespoon of vinegar or lemon juice to a measuring cup and add 1 cup of milk. Let it sit for 10 minutes to make a swap. Or use plain greek yogurt or sour cream that has been thinned out with milk as a swap.

What other potato can I use?

Russet works fine too. They will end up lighter and fluffier.
