Ingredients
- 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.
- Bacon bits – make it easy and buy a package of real bacon bits (not the imitation bits).
- 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 350ยฐF 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 Tips
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.
