This loaded baked potato casserole is everything you love about classic loaded potatoes—creamy, cheesy, and full of smoky bacon—baked into one comforting, crowd-pleasing dish. It’s rich, savory, and topped with a fresh hit of chives or green onion for that perfect finish.
4–5 large russet potatoes, peeled and cut into chunks
4 tbsp melted butter
Salt and pepper, to taste
2 cups shredded cheese (cheddar, Monterey Jack, or a mix)
1½ cups cooked bacon, chopped
½ cup chopped chives or green onion
Optional twist: ½ cup sour cream or cream cheese stirred into the potatoes for extra creaminess
Optional topping: extra cheese and bacon for a bubbly, golden top
Preheat oven to 375°F (190°C). Grease a 9×13” baking dish.
Boil potatoes: In a large pot, boil potatoes in salted water until fork-tender (about 10–12 minutes). Drain well.
Mash and mix: Return potatoes to the pot. Add melted butter, salt, and pepper. Mash until fluffy. Fold in 1½ cups cheese, bacon, and half of the chives/green onion. Add sour cream or cream cheese if using.
Assemble: Spread mixture evenly into prepared baking dish. Top with remaining cheese and extra bacon if desired.
Bake uncovered for 20–25 minutes, or until cheese is melted and bubbly.
Finish: Sprinkle with remaining chives or green onion before serving.
