Ingredients
  

Essential Ingredients:
  • 3 lbs Yukon Gold or Russet potatoes peeled and chunked
  • 1 cup whole milk or half-and-half warmed
  • 1/2 cup unsalted butter room temperature
  • 1/2 cup sour cream or full-fat Greek yogurt
  • Salt and black pepper to taste
Optional Flavor Enhancers:
  • 2 garlic cloves boiled alongside potatoes
  • Fresh herbs such as chives parsley, or dill for garnish

Method
 

  1. Prepare and Boil: Place potatoes (and optional garlic) in a large pot with cold, salted water. Bring to a gentle simmer and cook 15–20 minutes, until fork-tender.
  2. Drain and Steam Dry: Drain potatoes, return to hot pot, and let steam off moisture for 2 minutes.
  3. Mash: Use a potato ricer for the smoothest results or a hand masher for rustic texture. Avoid electric mixers to prevent gluey texture.
  4. Build Creaminess: Stir in butter first, then slowly add warm milk until desired consistency. Fold in sour cream for rich, tangy flavor.
  5. Season and Serve: Adjust seasoning with salt and pepper. Garnish with herbs and a pat of butter for presentation.

Notes

For ultra-smooth mashed potatoes, use a potato ricer and warm dairy before adding. Store leftovers for up to 4 days or freeze up to 3 months. Reheat gently with warm milk to restore creaminess.
