- 1 cup shredded cheddar cheese, divided
- 6 slices bacon, cooked and crumbled, divided
- 1/4 cup chopped green onions, divided
Instructions
- Boil Potatoes: Boil the peeled and chunked russet potatoes in a large pot of salted water until fork-tender, about 15 to 20 minutes.
- Mash Potatoes: Drain the cooked potatoes thoroughly and return them to the pot. Mash the potatoes until smooth and creamy.
- Add Dairy and Seasonings: Stir in sour cream, softened cream cheese, melted butter, whole milk, salt, black pepper, and garlic powder until the mixture is creamy and well combined.
- Mix in Half Toppings: Fold in half of the shredded cheddar cheese, half of the crumbled bacon, and half of the chopped green onions evenly into the mashed potato mixture.
- Prepare for Baking: Transfer the mashed potatoes into a greased 9×13-inch baking dish and spread evenly.
- Add Remaining Toppings: Sprinkle the remaining cheddar cheese and crumbled bacon evenly over the top of the mashed potatoes.
- Bake: Place the casserole in a preheated oven at 350°F (175°C) and bake for 20 to 25 minutes, or until the cheese is melted and the casserole is heated through.
- Garnish and Serve: Remove from oven and garnish with the remaining chopped green onions before serving warm.
Notes
- This casserole can be made ahead of time and refrigerated for up to 2 days before baking. Allow it to sit at room temperature for 30 minutes prior to reheating.
- For a vegetarian version, omit the bacon or substitute with plant-based bacon alternatives.
