Why I Love This Recipe
This casserole has all the best parts of a loaded baked potato, baked into one cohesive, dreamy dish:
- Creamy mashed potatoes, loaded with sour cream, cheddar, and butter
- Crispy bacon and fresh green onions for salty, savory contrast
- No stuffing or re-baking individual potatoes—just mix and bake
- The ultimate comfort food side or main dish
Ingredients
- 6–8 medium russet potatoes, baked and cooled
- 1 cup sour cream
- ½ cup milk
- 4 tbsp butter, melted
- 1½ cups shredded cheddar cheese, divided
- 6 slices bacon, cooked and crumbled
- 3 green onions, sliced
- Salt and pepper, to taste
Swaps & Add-Ins
- Make it a main: Add shredded rotisserie chicken or cooked sausage.
- Use Yukon Gold potatoes for a creamier texture.
- Spice it up with a pinch of cayenne or chopped pickled jalapeños.
- Swap sour cream for Greek yogurt for a lighter version.
Instructions
- Preheat and prep
Preheat oven to 350°F (175°C). Lightly grease a 9×13” baking dish. - Scoop and mash
Cut baked potatoes in half and scoop the insides into a large mixing bowl. Discard skins or save for another use.
Add sour cream, milk, melted butter, salt, and pepper, and mash until smooth and creamy. - Mix it up
Stir in 1 cup of cheddar cheese, half of the bacon, and half the green onions. - Assemble
Spread the mashed mixture evenly into the prepared baking dish.
Top with the remaining ½ cup cheddar and the rest of the crumbled bacon. - Bake
Bake uncovered for 20–25 minutes, or until hot and bubbling. - Garnish and serve
Sprinkle remaining green onions on top before serving. Serve warm.
Tips for Success
- Bake potatoes ahead: Do this the day before for even faster prep.
- Don’t over-mash: You want a creamy texture, not gluey potatoes.
- Use freshly shredded cheese for better melting and flavor.
- Bake uncovered so the top gets golden and slightly crisp.
