Loaded Baked Potato Casserole is the kind of comfort food that disappears fast the second it hits the table. It has everything people love about a classic loaded baked potato, but layered into one creamy, cheesy, oven-baked dish that feels a little more generous and a lot more shareable.

Every forkful brings tender potatoes, melty cheddar, crispy bacon, and a rich, velvety finish from sour cream and butter. It works beautifully for weeknight dinners, holiday spreads, potlucks, and those moments when you want a side dish that quietly steals attention from the main course.

Why You’ll Love This Loaded Baked Potato Casserole

This casserole is deeply satisfying without being complicated. It uses familiar ingredients, comes together in simple steps, and can be made ahead when you need something reliable. The texture is one of its best qualities. The potatoes stay soft and fluffy, the cheese melts right into the layers, and the bacon adds little bites of smoky crunch throughout.

It is also easy to adjust depending on what you have in the kitchen. You can make it extra cheesy, add green onions for freshness, or keep it simple and classic. Whether you serve it with roast chicken, grilled steak, or just a crisp salad, it always feels warm, hearty, and welcome.

What Kind of Potatoes Should I Use for Loaded Baked Potato Casserole?

Russet potatoes are the best choice for this casserole because they bake up fluffy and absorb all the creamy, buttery ingredients so well. They give you that true baked potato feel, which is exactly what makes this dish so comforting. Yukon Gold potatoes can also work if you want a slightly creamier texture, but the final dish will be a little denser and less airy.

If you want the casserole to taste like a classic steakhouse-style loaded potato, stick with russets. They hold up well after baking, mash easily, and give the casserole those soft, cloud-like pockets that pair perfectly with cheese, bacon, and sour cream.

Ingredients for the Loaded Baked Potato Casserole

The beauty of this dish is that every ingredient has a job to do. The potatoes build the heart of the casserole, the dairy ingredients make it creamy and rich, and the toppings bring that familiar loaded baked potato finish that makes it so hard to resist.

Ingredients

• 3 pounds russet potatoes: These create the fluffy, hearty base and give the casserole its true baked potato texture.
• 6 tablespoons unsalted butter: Butter adds richness and helps mash the potatoes into a smooth, flavorful filling.
• 1 cup sour cream: This brings tang, creaminess, and that classic loaded potato taste.
• 1/2 cup whole milk: Milk loosens the potato mixture just enough so it bakes up soft instead of heavy.
• 2 cups shredded sharp cheddar cheese, divided: Cheddar melts into the casserole and adds a bold, savory finish on top.
• 8 slices bacon, cooked and crumbled, divided: Bacon adds smoky crunch and gives the casserole its loaded character.
• 4 green onions, thinly sliced, divided: Green onions brighten the rich ingredients and add a fresh bite.
• 1 teaspoon garlic powder: Garlic powder gives the potatoes a gentle savory depth without overpowering them.
• 1 teaspoon salt: Salt brings out the flavor of the potatoes and balances the dairy.
• 1/2 teaspoon black pepper: Black pepper adds a little warmth and rounds out the seasoning.

How To Make the Loaded Baked Potato Casserole

A good loaded potato casserole is all about building flavor in layers and keeping the texture soft and creamy. Once the potatoes are cooked, the rest comes together quickly and the oven does the final work of melting everything into a bubbling, golden dish.

Step 1: Bake or Boil the Potatoes Until Tender

Peel the potatoes and cut them into large chunks. Place them in a large pot of salted water and boil until fork-tender, about 15 to 20 minutes. You can also bake the potatoes whole if you prefer a deeper baked potato flavor, then scoop out the insides once they are cool enough to handle.

Step 2: Mash the Potatoes With the Creamy Ingredients

Drain the potatoes well and return them to the warm pot. Add the butter, sour cream, milk, garlic powder, salt, and black pepper. Mash until the mixture is smooth but still has a little texture. Stir in 1 1/2 cups of the cheddar cheese, half of the bacon, and half of the green onions.

Step 3: Fill the Baking Dish

Preheat your oven to 375°F. Spoon the potato mixture into a greased 9×13-inch baking dish and spread it into an even layer. Sprinkle the remaining cheddar cheese over the top, followed by the rest of the bacon.

Step 4: Bake Until Hot and Bubbly

Bake for 20 to 25 minutes, or until the cheese is melted and the casserole is heated through. If you want a little extra color on top, broil it for 1 to 2 minutes at the end while watching closely.

Step 5: Finish and Serve

Remove the casserole from the oven and scatter the remaining green onions over the top. Let it rest for about 5 minutes before serving so the layers can settle slightly and scoop more cleanly.

How to Serve and Store Loaded Baked Potato Casserole

This casserole serves about 8 people as a side dish, though it can stretch a little further when part of a larger holiday or potluck spread. It is rich enough to feel special, but familiar enough that just about everyone reaches for seconds. Serve it hot with an extra spoonful of sour cream on the side if you want to lean into the loaded baked potato feel even more.

Leftovers store very well in an airtight container in the refrigerator for up to 4 days. Reheat portions in the microwave or warm the whole dish in the oven covered with foil until heated through. If the casserole seems a little firm after chilling, a splash of milk stirred in before reheating helps bring back its creamy texture.
