- Cubed potatoes – russet potatoes or Yukon gold potatoes work great.
- Unsalted butter
- Heavy cream
- Sour cream
- Kosher salt and black pepper
- Garlic powder
- Shredded sharp cheddar cheese – or try pepper jack cheese, Colby jack, or gruyere cheese.

- Sliced green onions – or chop up some fresh parsley or fresh chives for the garnish.
How to Make It
Boil the potatoes: Cook the potatoes in a pot of water until they’re fork-tender. It should only take about 15 minutes or so. Once they’re cooked, drain them and place them back in the pot.
Make the mashed potatoes: Mash the potatoes and then add the butter, cream, sour cream, and all of the seasonings. Stir well to combine, and then mix in half of the shredded cheese and half of the bacon.
Bake the casserole: Spread the potato mixture in a prepared 8×8″ baking pan. Sprinkle the rest of the cheese and bacon over the top. Bake the potato casserole at 350°F for 15 minutes or until hot, and the cheese is melted.
Garnish and serve: Sprinkle the sliced green onions over the top for serving.
Recipe yield: This serves six people as a side dish but if you’re serving more, you can double it and bake the casserole in a 9×13″ baking dish.
Make-ahead tip: You can cook and mash the potatoes a day ahead. Mix in the cheese, bacon, and seasonings, and then transfer the mixture to an airtight container. Store in the fridge, and then, the next day, just spread it in a casserole dish, add the rest of the cheese and bacon, and bake. It may need a little more time since the potatoes will be cold.
Leftovers: Store the leftover casserole in an airtight container. It will keep well in the refrigerator for two to three days.

- Category: Side Dishes
- Method: Bake
- Cuisine: American
- 2 pounds potatoes, peeled and cut into 1” cubes
- 4 tablespoons unsalted butter
- ¼ cup heavy cream
- ¼ cup sour cream
- ½ teaspoon kosher salt
- ½ teaspoon garlic powder
- ¼ teaspoon cracked black pepper
- 2 cups shredded cheddar cheese, divided
- 1 cup bacon bits, divided
- ¼ cup sliced green onion, for garnish
- Preheat the oven to 350°F and coat an 8” baking dish with nonstick cooking spray.
- Place diced potatoes in a large pot and cover them with water. Heat the pot over medium-high heat and cook the potatoes for 15 minutes or until they are fork-tender.
- Drain the potatoes and return them to the pot. Mash the potatoes and then add the butter, cream, sour cream, and seasonings. Stir to combine.
- Add 1 cup of cheddar cheese and ½ cup of bacon bits. Stir to combine. Transfer the casserole to your prepared baking dish and spread the mixture into an even layer. Sprinkle the rest of the cheddar cheese and bacon bits over the top of the potatoes.
- Bake the casserole uncovered for 15 to 20 minutes, or until the casserole is heated through and the cheese is melted. Garnish with sliced green onions for serving.
Make-ahead tip: You can make the mashed potatoes a day ahead and keep them in the refrigerator. When you’re ready to bake the casserole, spread the potato mixture in the baking dish. Top it with the rest of the cheese and bacon. Cover the dish with aluminum foil (this will help heat the potatoes faster). Bake it until the potatoes are heated through, and the cheese is melted. It will take a little longer to bake since the potatoes are cold.
If you’re serving a crowd, you can double this recipe and bake the casserole in a 9×13″ baking dish.
