Sour Cream and Dill Mashed Potatoes Recipe


  • Potatoes: 2 pounds russet potatoes (or Yukon Gold for a creamier texture), peeled and cut into 1-inch cubes
  • Butter: 4 tablespoons (1/2 stick) unsalted butter
  • Milk: 1/2 cup (whole milk preferred, but any kind works)
  • Sour Cream: 1/2 cup full-fat sour cream
  • Fresh Dill: 2 tablespoons chopped fresh dill (If you only have dried dill, use 1 teaspoon)
  • Salt: 1 teaspoon
  • Black Pepper: 1/2 teaspoon


1. Prep the potatoes

  • Wash, peel, and cut potatoes into equal-sized cubes for even cooking.

2. Cook the potatoes

  • Place potatoes in a large pot and cover with cold water.
  • Generously salt the water (this flavors the potatoes).
  • Bring to a boil over high heat, then reduce to a simmer. Cook until fork-tender, about 15-20 minutes. Be careful not to overcook.

3. Drain and dry

  • Drain potatoes thoroughly in a colander.
  • Return the empty pot to low heat for a minute to evaporate any remaining water. This prevents watery mashed potatoes.

4. Mash and add butter

  • Return potatoes to the pot.
  • Add butter and mash with a potato masher or ricer until mostly smooth. You can leave some small chunks for texture if you prefer.

5. Warm the dairy

  • In a small saucepan or microwave, gently warm the milk and sour cream (don’t boil).

6. Incorporate the goodness

  • Gradually add the warmed milk and sour cream to the potatoes, mashing until light and fluffy.
  • Stir in chopped dill, salt, and pepper.

7. Taste and adjust

  • Adjust seasonings to your preference. Add more salt, pepper, or dill as needed.

8. Serve

  • Serve warm with a dollop of extra butter and a sprinkle of fresh dill for garnish.


The right potatoes: Russet potatoes have a high starch content for fluffy mashed potatoes. Yukon Golds yield a naturally buttery, creamier result.

Fresh is best: Fresh dill adds amazing flavor, but dried dill can work in a pinch.

Don’t over-mash: Overworking releases too much starch, making potatoes gluey.

Customize: Consider adding a clove of roasted garlic, chives, or a sprinkle of cheese for extra flavor dimensions.
