Get ready to indulge in the most heavenly, creamy, and utterly delicious mashed potatoes you’ve ever tasted! Say goodbye to lumpy mashed potatoes with this easy-to-follow recipe that will leave your taste buds singing with joy. Made with perfectly cooked russet potatoes, velvety whole milk, and butter, these mashed potatoes will have you reaching for seconds (or thirds!).

  8. Serve


  • Use Russet Potatoes.
  • Make sure you rinse and soak the potatoes.
  • Do NOT use a hand mixer or food processor to mash potatoes.
  • It is important to use room temperature milk and butter. If you are in a hurry or don’t have time, bring your milk and butter to room temperature by heating in your microwave using a low power setting. I use power level two (out of ten) on my microwave for about 2-5 minutes to bring milk or butter to room temperature.
  • Add more salt and pepper if desired.
  • Like garlic? Add some garlic.
