Ingredient Notes

  • Yukon gold potatoes – I love using yukon gold potatoes for this recipe. They have a buttery and creamy texture, making your mashed potatoes so rich and delicious. They also have a thin skin, so you don’t have to worry about peeling them before cooking and mashing. Other potato options include russet potatoes and red potatoes. If you use russet potatoes, peel them first.
  • Sour cream – I love to use sour cream in mashed potatoes. It makes them really fluffy and moist and gives them a subtle tangy flavor. If you don’t have sour cream, use milk instead. 
  • Chopped chives – Adding chopped chives to these loaded mashed potatoes gives them a ton of flavor. You can also use green onions if you prefer. 
  • Thick-cut bacon – You’ll need to pre-cook your bacon before using in this recipe. I recommend my oven baked bacon method since you’ll have the oven on anyways, but you can also cook them in a skillet if you prefer. Cook the bacon at the same time the potatoes are boiling to save time. Roughly chop the bacon into small pieces before using.
  • Shredded cheddar cheese – Use your favorite shredded cheddar cheese for this recipe. I used a triple cheddar blend, which is a blend of mild cheddar, sharp cheddar and white cheddar.

Ingredients

  • 3 lbs yukon gold potatoes (washed and cubed into 1-inch pieces)
  • 2 teaspoons salt (divided)
  • 1/2 cup salted butter
  • 1 cup sour cream
  • 1/2 cup fresh chopped chives (plus more for garnish)
  • 1/2 teaspoon ground black pepper
  • 8 oz thick-cut bacon (cooked and diced, divided (about 6 thick cut slices))
  • 8 ounces shredded cheddar cheese

Instructions

  • Preheat the oven to 350F. Peel the potatoes and cube into 2-inch pieces.
  • Place the cubed potatoes in a large pot or dutch oven. Pour water over the potatoes so that they are completely covered. Add 1 teaspoon of the salt to the water.
  • Bring the potatoes to a boil. Reduce the heat and let simmer for 20 minutes, until the potatoes are fork tender. Drain the water, and return the potatoes to the pot.
  • Mash the potatoes until relatively smooth. A few lumps are okay.
  • Add the sour cream, butter, ground black pepper, and remaining 1 teaspoon of salt to the potatoes. Stir until the butter is melted and everything is evenly distributed.
  • Add the chives, half of the bacon and cheese, reserving the rest for later. Mix until combined.
  • Spoon the mashed potatoes into a greased 9×13-inch casserole dish.
  • Top with remaining bacon and cheese.
  • Bake at 350F for 20-30 minutes, until the cheese is melted on top. Serve warm with additional fresh chives if desired.

Notes

  • I love yukon gold potatoes in this recipe. The skin is thin, so you don’t need to peel the potatoes before cooking and mashing. However, if you like a smoother mashed potato texture, you can peel the potatoes first. 
  • You can also use red potatoes or russet potatoes in this recipe. If you use russet potatoes, I’d recommend peeling them first. Red potatoes you can either leave the skin on or peel them. 
  • I used a triple cheddar cheese that is a combination of mild cheddar, sharp cheddar and white cheddar cheeses. I love the combination that this brings. However, you can use your favorite cheddar cheese.
