Ingredients
  

russet potatoes
  • 4 lb russet potatoes, peeled and cubed
salt for the water
  • 1 tbsp salt for the water
salt
  • 1 tsp salt
salted butter
  • 0.5 cup salted butter
evaporated milk
  • 0.5 cup evaporated milk
sour cream
  • 0.5 cup sour cream
whole milk, warmed
  • 0.25 cup whole milk, warmed
black pepper
  • 0.5 tsp black pepper

Equipment

  • 1 Dutch oven

Method
 

Boil and drain
  1. Boil the potatoes in salted water for 15-20 minutes until very tender, stirring occasionally for even cooking. Visual cue: the largest cubes should break easily when pressed with a fork.
  2. Drain the potatoes well and return them to the pot over low heat for 1 minute to dry. Visual cue: the steam should look lighter and the potatoes should look slightly matte.
Mash and finish creamy
  1. Mash with butter until smooth. Visual cue: no visible chunks remain and the mixture looks thick and glossy.
  2. Stir in the evaporated milk, sour cream, and warm milk until creamy. Visual cue: the mash loosens into a uniform, silky texture.
Season and serve
  1. Season with salt and plenty of black pepper. Visual cue: pepper flecks are visible throughout, not just on top.
  2. Make a well in the center and add an extra pat of butter; serve immediately. Visual cue: a small butter pool forms in the center when the mash is hot.

Notes

For the smoothest texture, dry the drained potatoes over low heat for the full 1 minute before mashing—this helps prevent watery mash. Refrigerate leftovers in an airtight container up to 3 days; reheat gently on the stovetop with a splash of milk. Freezing is not recommended because sour cream can slightly grain after thawing. Dietary swap: use unsalted butter and swap the sour cream for plain Greek yogurt if you want a lighter tang, but keep seasoning adjustments.
