Buttermilk Mashed Potatoes Recipe Questions Answered:

What is the best potato for mashing?

When selecting your potatoes you want to go with ones that are higher in starch. Russets or Yukon golds are perfect for this. These potatoes turn out fluffy, smooth, and hold the most flavor in the mashed potatoes.

Other types of potatoes like red or white ones are waxier and therefore, take more mashing to become smooth. Too much mashing can lead to gross potatoes that are more like paste instead of fluffy creamy deliciousness. 

How can I thicken my mashed potatoes?

If you need to thicken your mashed potatoes, add 1 TBS of flour, cornstarch, or powdered milk to your potatoes. Mix it into your potatoes with a wooden spoon until they become smooth. 

How many potatoes do I need to make mashed potatoes for 4 people?

As a general rule, you should plan to use ½ pound of potatoes per person. So for example, if you are planning on 10 people, use 5 pounds of potatoes or for 4 people, use 2 pounds of potatoes. 

How to make the Best Buttermilk Mashed Potatoes: 

1. First, add the potatoes, butter, buttermilk, water, baking soda, and 1 teaspoon salt to Dutch oven and mix to combine. 
2. Next, bring it to a boil, cover, and reduce heat to low. Let it simmer, stirring occasionally, for about 20-25 minutes. Remove the lid and cook over medium heat until liquid has just about evaporated.
3. Then turn off the heat, add remaining butter to the pot and mash with a potato masher until smooth. Next, using a rubber spatula, fold in remaining buttermilk until absorbed and potatoes are creamy.
4. Finally, season with salt and pepper and serve. 

How to Make Buttermilk Mashed Potatoes Ahead of Time:

You can make this complete recipe ahead of time, and store it in the refrigerator up to 3 days in advance. Then you can heat them up by placing them in a crockpot on warm at least 2 hours in advance or use the microwave to bring them up to temperature. If you use the microwave, it’s best to separate the potatoes into 2 smaller batches to heat evenly.
