Necessary Kitchen Equipment

Large mixing bowl
Potato masher or fork
Baking dish (9×13-inch)
Aluminum foil

Ingredients

4 pounds russet potatoes, peeled and cubed
1 cup sour cream
1 cup whole milk
½ cup unsalted butter, melted
2 cups shredded cheddar cheese, divided
1 cup cooked bacon, crumbled (reserve some for garnish)
½ cup green onions, chopped (reserve some for garnish)
1 teaspoon garlic powder
1 teaspoon salt
½ teaspoon black pepper

Step-by-Step Instructions

1. Preheat the Oven:

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.

2. Cook the Potatoes:

Place the cubed potatoes in a large pot of salted water. Bring to a boil and cook until the potatoes are fork-tender, about 15-20 minutes. Drain the water and return the potatoes to the pot.

3. Mash the Potatoes:

Using a potato masher or fork, mash the potatoes until smooth. Add the sour cream, milk, butter, garlic powder, salt, and pepper. Stir until well combined.

4. Add Mix-Ins:

Fold in 1½ cups of cheddar cheese, most of the bacon, and most of the green onions. Mix until evenly distributed.

5. Assemble the Casserole:

Transfer the potato mixture to the prepared baking dish. Spread it out evenly and sprinkle the remaining ½ cup of cheddar cheese over the top. Cover with aluminum foil.

6. Bake:

Bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.

7. Garnish and Serve:

Remove the casserole from the oven and sprinkle with the reserved bacon and green onions. Serve hot and enjoy!

Recipe Tips

Make Ahead: Assemble the casserole up to a day in advance and refrigerate. Bake just before serving.
Cheese Variety: Swap cheddar for Monterey Jack, mozzarella, or a blend for a twist.
Lighten It Up: Use Greek yogurt in place of sour cream for a healthier option.
