Ingredients and Cost
Per Serving Cost: $0.64
Recipe Cost: $5.15
- 4 pounds Yukon Gold potatoes – $2.78
- 12 Tablespoons unsalted butter – $1.20
- 2 cups buttermilk – $1.16
- ¾ cup water – $0.00
- ¼ teaspoon baking soda – $0.01
NOTE: The recipe prices are calculated by using grocery store websites. The actual cost of the recipe will vary depending on what ingredients you already have.
- First, add the potatoes, butter, buttermilk, water, baking soda, and 1 teaspoon salt to Dutch oven and mix to combine.
- 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.
- 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.
- 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 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 two smaller batches to heat them evenly.
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. However, too much mashing can lead to gross potatoes that are more like paste instead of fluffy, creamy deliciousness.
If you need to thicken your mashed potatoes, add 1 tablespoon of flour, cornstarch, or powdered milk to your potatoes. Mix it into your potatoes with a wooden spoon until they become smooth.
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.
- This recipe doubles and halves beautifully, so adjust as needed for the number of guests you’re serving!
- This recipe serves 8, but since there are usually a TON of different sides at Thanksgiving I’d say you can get a good 10 servings out of this recipe.
SERVE: As with most recipes with dairy products in them, you shouldn’t leave this out for longer than 2 hours.
STORE: Cover and store leftovers in the refrigerator for up to 3 days.
FREEZE: Once cooled, place the potatoes in a freezer-safe container or Ziploc bag. Freeze for 3-4 months.

I am all about mashed potatoes, and this one looks like a winning recipe! Bookmarked to make for later, thank you so much for the recipe 🙂
These mashed potatoes look so creamy and fluffy. I am going to try it with buttermilk next time.
I always add sour cream to my mashed potatoes to enhance the flavor and make it creamy. Never used buttermilk before but it gives it a nice flavor boost as well!
Mmmm love how silky smooth these turned out! So buttery and yummy.

why the baking soda ?
It helps prevent the buttermilk from breaking while the potatoes cook.
