Wash 2 pounds of red potatoes and cut them into quarters, leaving the skins on.
Place the potatoes in a large pot and cover them with water. Bring to a boil and simmer for about 10-15 minutes until the potatoes are fork tender.
Drain the potatoes and then return them back to the pot.
Add 2 teaspoons minced garlic, 1 packet (1 ounce) ranch seasoning mix, ¼ cup butter, ½ teaspoon salt, and ½ cup milk. Beat the potatoes with a hand mixer until light and fluffy.
Mix in 1 cup sour cream. Gradually add the remaining ¼ cup milk until the mashed potatoes reach your desired consistency.
Preheat the oven to 350 degrees Fahrenheit and place the mashed potatoes in a 9X9 baking pan.
Top with 2 cups shredded cheddar cheese, 6 slices cooked and crumbled bacon, and ½ cup chopped fresh chives.
Cover with foil (slightly tent the foil so that it does not stick to the cheese) and bake for 10-15 minutes until the cheese is completely melted.
