Buttermilk Mashed Potatoes

  • 2/3 cup Standard Potato Flakes
  • 1 cup Buttermilk


  • 1/2 cup Buttermilk Mashed Potatoes
  • 1/4 pound Unsalted Butter
  • 1/4 cup Sour Cream
  • 1/4 cup Fresh chives, minced
  • 1 Tablespoon Bacon grease, duck fat, or tallow (optional)
  • 3/4 teaspoon Kosher Salt


  1. Prepare buttermilk mashed potatoes: place standard potato flakes into a food processor and pulverize into a fine powder. Add buttermilk and pulse until combined. Let rest 10 minutes to rehydrate. Set aside ½ cup and reserve the rest for another use.

  2. In a stand mixer fitted with the paddle attachment, blend mashed potatoes, butter, sour cream, chives, bacon grease (if using), and salt until well combined.

  3. Using a #60 disher, scoop servings onto parchment lined baking sheet. Cover with plastic wrap and refrigerate until service. Alternatively, place butter onto plastic wrap and form into a log and refrigerate or freeze. Use a hot knife to slice half-ounce portions for service.
