Onion Mashed Potatoes

Prep Time: 15 minutes | Cook Time: 30 minutes | Total Time: 45 minutes | Servings: 6

Ingredients

  • 3 lbs russet potatoes, peeled and cut into 1-inch chunks
  • 1 medium yellow onion, finely diced
  • 3 tablespoons unsalted butter, divided
  • 3/4 cup whole milk, warmed
  • 1/4 cup sour cream
  • 1 teaspoon garlic powder
  • 1 teaspoon salt, plus more for boiling water
  • 1/2 teaspoon black pepper
  • 2 tablespoons fresh chives or green onions, chopped (optional, for garnish)

Instructions

  1. Boil the potatoes. Place potato chunks in a large pot and cover with cold, salted water. Bring to a boil over high heat, then reduce to a steady simmer. Cook for 18—22 minutes, until potatoes are fork-tender all the way through. Drain well and return to the warm pot.
  2. Caramelize the onion. While potatoes cook, melt 1 tablespoon butter in a skillet over medium heat. Add the diced onion and a pinch of salt. Cook, stirring occasionally, for 15—18 minutes until onions are soft, golden, and fragrant. Remove from heat and set aside.
  3. Mash the potatoes. Add the remaining 2 tablespoons of butter to the drained potatoes. Mash with a potato masher or hand mixer until butter is melted and potatoes begin to break down.
  4. Incorporate the dairy. Pour in the warmed milk and add the sour cream. Continue mashing or mixing until potatoes are smooth and creamy. Adjust milk quantity as needed for your preferred consistency — some like them stiff, some like them loose.
  5. Fold in the onions. Stir in the caramelized onions, garlic powder, salt, and black pepper. Taste and adjust seasoning as needed.
  6. Serve warm. Transfer to a serving bowl and top with chives or green onions if desired. Serve immediately alongside chicken fried steak, pot roast, or any meal that needs a little grounding.
