  • pot for boiling potatoes
  • sheet pan
  • spatula
  • oven


  • 2-1/2 pounds potatoes New, Red, or small Yukon Gold, washed
  • 1/4 cup (approximately) avocado oil for drizzling; you may use duck fat, if preferred (melted)
  • sea salt to taste


  • Place potatoes in large pot. Cover with water by 1". Boil slowly until fork tender, about 25 minutes, depending on their size. Drain and cool potatoes. Refrigerate them overnight or for 4 to 6 hours.

  • Grease large cookie sheet with avocado oil or duck fat. Set aside.
  • Preheat oven to 400 degrees Fahrenheit. With the back of an offset spatula, smash each potato. (I like to smash each one twice, as the thinner they are, and the more smashed, the more bits get crispy and flavorful.)

  • Place onto prepared greased cookie sheet. Drizzle generously with avocado oil and sprinkle with sea salt. (Use your fingers to rub the top of each potato with the oil.)

  • Bake 25 minutes, then flip each potato. (If some are a lot darker, you can rotate them around so the darker ones get moved to the center of the pan, and the lighter ones are moved to the edges.) Bake 10 additional minutes. Serve.
