Sour Cream and Onion Potato Bake

Prep Time15 minutes
Cook Time30 minutes
Total Time45 minutes
Servings: 8

Ingredients

  • 3 pounds russet potatoes, peeled and quarted
  • 1 tablespoons plus 2 teaspoons kosher salt, divided
  • 4 tablespoons salted butter, divided
  • 2 cups thinly sliced yellow onions (from about 1 medium onion)
  • 3 garlic cloves, minced
  • 1 cup light sour cream
  • 1/2 cup freshly chopped chives, divided
  • 1/4 cup low-sodium chicken broth
  • 2 teaspoons white vinegar
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 cup shredded mild cheddar cheese

Instructions

  • Preheat the oven to 375℉.
  • Place the potatoes in a large pot and fill with water to cover the potatoes by 2 inches. Bring to a boil. Once boiling, add 1 tablespoon salt and continue to boil until potatoes are fork-tender, about 10 minutes.
  • Meanwhile, heat a large skillet over medium heat with 2 tablespoons butter. Add the onions and garlic and cook, stirring, until the onions are tender, 4 to 6 minutes. Set aside.
  • When potatoes are tender, strain and let the steam escape from the colander, about 5 minutes.
  • In a large mixing bowl, add the sour cream, chives, chicken broth, vinegar, black pepper, and remaining 2 tablespoons butter. Add the potatoes and mash to your desired consistency.
  • Add the onions, garlic, black pepper, and remaining 2 teaspoons salt. Stir to combine.
  • Transfer the potatoes to an oven-safe 9x13-inch baking dish, spread into an even layer, and sprinkle with cheddar cheese. Bake, uncovered, until the cheese is lightly browned, 10 to 15 minutes.
  • Top with remaining chives, serve, and enjoy!
