Loaded Mashed Potato Casserole

Loaded Mashed Potato Casserole builds on creamy mashed potatoes blended with sour cream, milk, butter, salt, and pepper, then mixed with cheddar cheese, crumbled bacon, and green onions. This combination is baked until bubbly with a melted cheese topping, creating a hearty comfort dish that combines smooth, fluffy potatoes with savory, smoky bacon and sharp cheese. It serves well as a side or main dish and can be adjusted in quantity for different serving sizes.

Description

The Loaded Mashed Potato Casserole recipe starts by boiling peeled and cubed Russet or Yukon potatoes until fork-tender. Once drained, potatoes are mashed with sour cream, milk, butter, salt, and black pepper to create a creamy, fluffy base. Cheddar cheese, crumbled cooked bacon, and chopped green onions are folded into the mashed potatoes, adding depth in flavor and texture. The mixture is then spread into a greased baking dish, topped with additional shredded cheddar, and baked at 350°F until the cheese melts and the casserole is heated through.

The result is a rich and savory dish with smooth mashed potatoes elevated by the cheesy topping and smoky bacon. The green onions contribute a fresh bite and subtle pungency. The baking step melds those flavors and creates a slightly browned cheese crust on top. This casserole works well as a satisfying side dish for dinner or as a hearty meal on its own. It pairs well with roasted or grilled meats and vegetables.

This dish can be halved if cooking for fewer people, offering flexibility. Using Russet or Yukon potatoes provides a creamy texture, but other starchy potatoes may be used if preferred. The addition of sour cream and milk contributes moisture and richness, while crumbled bacon adds a smoky, salty contrast.
