Ingredients
  

Ingredients for Sour Cream Mashed Potatoes
  • 3 lbs yukon potatoes or russet potatoes (peeled and quartered)
  • 1/2 cup milk
  • 8 tbsp unsalted butter softened
  • 10 tbsp sour cream or 1/2 cup plus 2 tbsp
  • salt and pepper for taste

Equipment

  • large pot
  • potato masher
  • ricer
  • microwave
  • serving bowl

Method
 

  1. Add the peeled and quartered potatoes to a large pot. Fill the pot with enough cold water to just cover the potatoes. Place the pot on medium-high heat and bring to a boil. Cook for 20-25 minutes, or until the potatoes are fork tender. Drain the potatoes thoroughly.
  2. Return the drained potatoes to the pot. Cover with a lid and let them sit for 5 minutes. This step helps remove excess moisture for fluffier mashed potatoes.
  3. Heat the milk in the microwave until hot (but not boiling). Add half of the hot milk, softened butter, and sour cream to the potatoes. Mash using a potato masher or ricer until smooth and creamy. If the mashed potatoes are too thick, add more hot milk a little at a time, stirring after each addition, until you reach your desired consistency.
  4. Stir in salt and pepper to taste. Transfer to a serving bowl and top with pats of butter for extra richness. Serve immediately Sharing is caring, so please share this recipe, so other people can enjoy it!

Notes

For the creamiest potatoes, start with Yukon Golds; they have a naturally buttery texture that makes them ideal. Heating the milk before adding it helps it absorb into the potatoes more evenly, preventing lumps. Be careful not to over-mash the potatoes; over-mashing can release too much starch, resulting in gummy potatoes.

Common Mistakes to Avoid When Making Mashed Potatoes

One common mistake is overcooking the potatoes, which can make them waterlogged. Using cold milk can also lower the temperature of the potatoes, resulting in a gluey texture. Finally, avoid over-mashing! Over-mashing releases too much starch and makes the potatoes gummy.

Store leftover mashed potatoes in an airtight container in the refrigerator for up to 3 days. To reheat, microwave in 1-minute intervals, stirring in between. You can also reheat them on the stovetop over low heat, adding a splash of milk to prevent drying out. Reheating in the oven is also an option, just be sure to add a splash of milk or butter.
