Ingredients

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.

You can leave the skin on potatoes that have thinner skins, like red potatoes or yukon gold potatoes. However, if you don’t like the added texture, peel them first!
