Buttermilk mashed potatoes are a creamy, tangy twist on the classic mashed potato dish. Add to it perfectly caramelized onions, and your dish is elevated to a new high.
Peel and quarter the potatoes. Combine with cold well salted water to cover by 1 inch in a saucepan. Bring to a simmer, and simmer until tender, about 20 minutes
Meanwhile, melt butter in a small saucepan over moderate heat. Add the shallots and cook, stirring frequently, until softened and deep golden, about 8 minutes.
Drain potatoes in a colander, return to pan, and mash to desire consistency with a potato masher.
Stir in the shallots, buttermilk salt and pepper to taste.
Notes
Use starchy potatoes like Yukon Gold or Russet potatoes to give it a buttery texture.
Adjust the seasoning before serving, and add more salt or black pepper as needed.
Do not rush the process of the caramelized onions. You want to cook them over moderate heat and stir them frequently to achieve that uniform golden color.
I always dry out the potatoes before proceeding with the recipe. This step will remove any excess liquid from your mashed potatoes and prevent them from being too soft and liquidy.
If you wish for finer potatoes, use a potato ricer in lieu of the masher.
