Cook Time: 45 minutes

Ingredients

• 3 pounds russet potatoes, peeled and quartered
• 1 1/2 teaspoons salt, divided
• 1 teaspoon olive oil
• 2 cups chopped onions
• 3 cloves garlic, minced
• 1 tablespoon sugar
• 1 tablespoon white vinegar
• 1 1/2 cups sour cream
• 1 cup buttermilk
• 1/4 cup salted butter
• 1/2 teaspoon freshly ground black pepper
• 4 green onions, chopped
• 1 bunch green chives, chopped, plus more for garnish
• 1/2 cup shredded white Cheddar cheese
• 1/2 cup crushed sour cream and onion potato chips

Directions

Step 1: Gather all ingredients.

Step 2: Preheat the oven to 375F (190C).

Step 3: In a 6 to 8-quart pot, combine the potatoes and 1 tablespoon of salt. Cover with water and bring to a boil over high heat. Once boiling, reduce the heat to medium and simmer for about 25 minutes, or until the potatoes are very tender.

Step 4: While the potatoes are cooking, heat olive oil in a large skillet over medium heat. Add the onions, garlic, sugar, and vinegar. Cook the onion mixture for 20 minutes, stirring occasionally, until the onions are tender and caramelized. If necessary, add water, 1 tablespoon at a time, to prevent sticking. Set the mixture aside.

Step 5: Once the potatoes are cooked, drain them and return them to the pot. Increase the heat to high and stir the potatoes for 30 seconds to remove any excess cooking liquid.

Step 6: Remove the pot from heat. Add the remaining 1 1/2 teaspoons salt, sour cream, buttermilk, butter, and black pepper to the potatoes. Use a potato masher to mash the potatoes until smooth and fluffy.

Step 7: Stir in the cooked onion mixture, green onions, and chives. Mix until everything is well combined.

Step 8: Transfer the mixture to a 2-quart baking dish. Sprinkle with shredded Cheddar cheese and crushed potato chips.

Step 9: Bake in the preheated oven for about 20 minutes, or until the cheese is melted and bubbly.

Step 10: Garnish with additional chopped fresh chives before serving.
