Some recipes stick around for a reason, and this one has that dependable, old-school comfort that makes people come back for seconds before the table is even fully set. It started as a clipped magazine recipe in the 1970s and earned its place by being simple, filling, and made from a handful of familiar ingredients that turn into something a little more special once they hit the oven. It is exactly the kind of dish I love for busy weeks and family get-togethers, because it feels nostalgic without being fussy.
This rich, cozy casserole fits right in next to baked ham, roast chicken, meatloaf, pork chops, or even a simple grilled steak. For a family-style meal, I like to serve it with a crisp green salad, roasted broccoli, or green beans to balance the creamy texture, and it also works beautifully on a holiday table with all the classic comfort-food sides.
Oven Baked 5-Ingredient Twice Baked Potato Casserole
Servings: 8
Ingredients
4 pounds russet potatoes, scrubbed
Directions
1. Preheat the oven to 400°F. Pierce the russet potatoes with a fork, place them directly on the oven rack or on a foil-lined baking sheet, and bake for 50 to 60 minutes, until very tender when pierced.
2. Let the potatoes cool just enough to handle. Split them open, scoop the flesh into a large mixing bowl, and discard the skins. Add the sour cream, melted butter, 2 cups of the cheddar cheese, and about three-quarters of the crumbled bacon. Mash and stir until creamy with a few small lumps for texture.
3. Lower the oven temperature to 375°F. Spread the potato mixture evenly into a greased 9x13-inch glass casserole dish. Top with the remaining 1/2 cup cheddar cheese and the rest of the bacon.
4. Bake for 20 to 25 minutes, until hot throughout and the cheese is melted and lightly browned on top. Let the casserole rest for 5 minutes before serving.
Variations & Tips
Make-ahead tip: Assemble the casserole up to a day in advance, cover tightly, and refrigerate. When you are ready to bake, let it sit at room temperature for about 20 minutes first so it heats more evenly.
Extra cheesy version: If your family likes an even richer casserole, add an extra 1/2 cup cheddar to the potato mixture. It makes the center a little more decadent and gives you that classic steakhouse-style feel.
Texture tip: For the best fluffy texture, mash the potatoes while they are still warm and avoid overmixing once the dairy goes in. That keeps the casserole light instead of dense or gummy.
Bacon shortcut: If you are pulling dinner together on a busy weeknight, cook the bacon ahead of time and keep it in the fridge. Then this casserole comes together fast once the potatoes are baked.
