Tips For The Best Buttermilk Mashed Potatoes
- When making mashed potatoes, it is important to mash the potatoes as soon as you take them off the fire and drain them. This ensures that you get the potatoes as creamy as possible. When you let them cool down, they become harder to mash and they get undesirably lumpy.
- Remove the buttermilk from the fridge ahead of time and bring it to room temperature before adding it to the potatoes. This ensures that the buttermilk is not too cold which makes the temperature of the potatoes change quickly.
- Mash the potatoes first with a potato masher to break them down then whip the potatoes using an electric hand mixer to get them, fluffy.
- When using an electric hand mixer to whip potatoes, be careful not to overbeat them as they could quickly become gluey. Once the potatoes are creamy and fluffy, stop mixing.
- You could use a stand mixer to make the mashed potatoes., Again, be careful not to overmix as the potatoes could turn gluey.
- It is okay for your mashed potatoes to not be ultra smooth. You want to mash them to be as smooth and creamy as possible but a few little lumps here and there are just fine.
You can make mashed potatoes your own by trying the following substitutions.
- Vegan or Dairy Free – swap the buttermilk for plant-based milk and replace the real butter with vegan butter.
- Potatoes – experiment with any potatoes you have on hand.
- Regular Milk – the buttermilk can be replaced with regular milk if that is your preference.
- Loaded Mashed Potatoes – consider adding some cheese and bits of bacon to your mashed potatoes to make loaded mashed potatoes.
- Garlic Mashed Potatoes – consider adding a full bulb of garlic when boiling the potatoes. Then mash all the garlic together with the potatoes for Garlic Mashed Potatoes. You could also use oven-roasted garlic for this.
- Spicy Mashed Potatoes – consider adding a little cayenne pepper to make the mashed potatoes spicy.
- Mashed Potatoes With Your Favorite Seasonings – consider adding your favorite seasonings to mashed potatoes. Seasoning such as Italian seasoning, Cajun seasoning, or your favorite all-purpose seasoning blend would work well.

A good ole potato masher or potato ricer could work for making mashed potatoes. Also, a handheld mixer or stand mixer could help make the process of making mashed potatoes easier.
Store mashed potatoes covered in an airtight container in the fridge for 2-3 days. Simply reheat in the microwave.
