Rich, velvety mashed potatoes infused with nutty brown butter and aromatic fresh sage. This easy, crowd-pleasing side dish is perfect for holidays, family gatherings, or cozy weeknight dinners.

Ingredients

Scale
  • 3 lbs Yukon Gold potatoes, peeled and cut into 2-inch chunks
  • 8 tbsp unsalted butter
  • 810 fresh sage leaves, washed and dried
  • 1 cup whole milk
  • 1/2 cup sour cream
  • 2 tsp kosher salt, plus more to taste
  • 1/2 tsp black pepper
  • 2 garlic cloves, peeled and smashed (optional)

Instructions

  1. Peel the Yukon Gold potatoes and cut them into even 2-inch chunks.
  2. Place potatoes in a large pot and cover with cold water. Add 2 tsp kosher salt and smashed garlic cloves if using.
  3. Bring to a boil over medium-high heat, then reduce to a simmer. Cook for 15-20 minutes, or until fork-tender.
  4. Drain potatoes in a colander, then return to the hot pot. Let sit uncovered for 2-3 minutes to steam off excess moisture.
  5. Meanwhile, melt 8 tbsp unsalted butter in a small skillet over medium heat. Add sage leaves and cook, swirling often, until butter foams, turns golden brown, and smells nutty (about 3-4 minutes). Remove from heat when sage is crisp.
  6. Mash the warm potatoes using a potato masher until mostly smooth (or use a ricer/food mill for extra silky texture).
  7. Pour in 1 cup warm whole milk and 1/2 cup sour cream. Stir gently until incorporated. Add more milk if potatoes are too stiff.
  8. Fold in the brown butter and sage mixture. Sprinkle in 1/2 tsp black pepper and mix gently to combine.
  9. Taste and adjust salt or pepper as needed. For richer flavor, add an extra pat of butter or spoonful of cream.
  10. Transfer mashed potatoes to a serving bowl. Garnish with extra crisped sage leaves or a drizzle of brown butter if desired.

Notes

For best results, use Yukon Gold potatoes for a creamy texture. Let potatoes steam dry after draining to avoid watery mash. Watch the butter closely while browning to prevent burning. Warm milk before adding to potatoes for smooth texture. Recipe is flexible—swap herbs or use plant-based dairy for dietary needs.
