This recipe delivers creamy mashed potatoes with rich brown butter and fresh chives, perfect for make-ahead holiday sides or comforting weeknight meals. The brown butter adds a deep, toasty flavor while the chives provide a fresh, mild onion punch.

Ingredients

Scale
  • 3 pounds russet potatoes, peeled and cut into chunks
  • 1 teaspoon kosher salt, for boiling
  • 4 tablespoons unsalted butter, cubed
  • 1/2 cup heavy cream, warmed
  • 1/4 cup sour cream
  • 6 tablespoons unsalted butter, browned
  • 2 tablespoons fresh chives, finely chopped
  • Freshly ground black pepper, to taste (optional)
  • Pinch of garlic powder (optional)

Instructions

  1. Place peeled and chunked potatoes in a large pot. Cover with cold water by about an inch and add 1 teaspoon kosher salt. Bring to a boil over high heat, then reduce to medium and cook until potatoes are fork-tender, about 15-20 minutes.
  2. Drain potatoes well in a colander and return them to the hot pot. Place over low heat for 1-2 minutes, shaking gently to dry excess moisture.
  3. Use a potato masher or ricer to mash potatoes until mostly smooth. Avoid using a blender or food processor to prevent gummy texture.
  4. In a small saucepan, warm the heavy cream and cubed butter over low heat until butter melts and mixture is hot but not boiling.
  5. In a separate small saucepan, melt 6 tablespoons of butter over medium heat. Watch carefully as the butter foams and then starts to turn golden brown with nutty aroma (about 3-4 minutes). Remove from heat immediately to avoid burning.
  6. Pour the warm cream and butter mixture into the mashed potatoes and stir gently but thoroughly. Fold in sour cream and season with salt, black pepper, and garlic powder if using.
  7. Drizzle the browned butter over the mashed potatoes and fold in the chopped chives. Taste and adjust seasoning if needed.
  8. For make-ahead: Transfer mashed potatoes to a buttered baking dish, cover tightly with foil or plastic wrap, and refrigerate up to 2 days. Reheat in a 350ยฐF oven for 25-30 minutes until warmed through, stirring halfway.

Notes

Do not overmix the potatoes to avoid a gluey texture. Watch the butter carefully when browning to prevent burning. Russet potatoes are best for fluffy texture. Dry potatoes well after boiling to prevent watery mash. Make-ahead mashed potatoes reheat well in the oven with foil to retain moisture. Optional seasonings like garlic powder or black pepper can be added to taste.
