This Loaded Twice Baked Potato Casserole is everything I want in a comfort food side dish. It has fluffy potatoes, creamy sour cream, melty cheddar, crispy bacon, and a golden cheesy top that bubbles up beautifully in the oven. Every scoop tastes like the best part of a loaded baked potato, only warmer, richer, and made for sharing.

I love making this when I need something cozy and dependable for family dinners, potlucks, or holiday tables. It feels special enough for celebrations, but it is also easy enough to pull together on a weeknight when you want something hearty and satisfying.

Why You’ll Love This Loaded Twice Baked Potato Casserole

This casserole is pure comfort in a baking dish. The texture is creamy without being heavy, the bacon adds smoky crunch, and the cheese gives every bite that irresistible pull. It is also a great make-ahead option, which makes life easier when you are cooking for guests.

You will also love how flexible it is. You can serve it beside roasted chicken, steak, pork chops, or even enjoy it as the star of a casual dinner with a simple salad on the side.

What Makes Loaded Twice Baked Potato Casserole So Good?

The magic comes from building layers of flavor into mashed baked potatoes instead of starting with boiled potatoes alone. Baking the potatoes first helps them develop a deeper potato flavor and a drier texture that turns extra fluffy when mashed. Once sour cream, butter, cheese, bacon, and green onions are folded in, the whole dish tastes like a classic steakhouse side in casserole form.

It is also a recipe that hits the perfect balance of creamy, cheesy, savory, and satisfying. The top gets lightly golden while the inside stays soft and rich, so every spoonful gives you contrast and comfort at the same time.

Ingredients for the Loaded Twice Baked Potato Casserole

You only need a few familiar ingredients to make this casserole taste full, rich, and loaded with flavor.

Russet potatoes
These are the best choice because they bake up fluffy and mash beautifully, giving the casserole its soft and hearty base.

Butter
Butter adds richness and helps the potatoes turn smooth and velvety.

Sour cream
This brings creamy texture and a little tang that keeps the casserole from tasting too heavy.

Milk
A splash of milk loosens the mixture just enough so it stays soft and scoopable.

Cheddar cheese
Sharp cheddar adds bold cheesy flavor both inside the casserole and on top.

Bacon
Crispy bacon brings smoky, salty flavor that makes the dish taste like a fully loaded baked potato.

Green onions
These add freshness and a mild onion bite that brightens the rich potatoes.

Salt
Salt helps bring out the natural flavor of the potatoes and balances the dairy.

Black pepper
Black pepper adds gentle warmth and a little savory depth.

Garlic powder
A little garlic powder rounds out the casserole with easy, cozy flavor.

How To Make the Loaded Twice Baked Potato Casserole

This recipe comes together in simple stages, and each step builds flavor into the final casserole.

Step 1: Bake the Potatoes

Bake the russet potatoes until they are fork tender and the insides are soft. Let them cool just enough to handle so you can scoop out the flesh easily.

Step 2: Mash the Filling

Add the potato flesh to a large bowl with butter, sour cream, milk, salt, pepper, and garlic powder. Mash until smooth and creamy, leaving a little texture if you like a more rustic finish.

Step 3: Stir in the Good Stuff

Fold in most of the cheddar cheese, most of the bacon, and part of the green onions. This makes sure every bite has cheesy, smoky flavor throughout the casserole.

Step 4: Fill the Baking Dish

Spread the potato mixture into a greased baking dish and smooth the top. Sprinkle the remaining cheddar cheese and bacon evenly over everything.

Step 5: Bake Until Hot and Golden

Bake until the casserole is heated through and the cheese on top is melted and lightly golden around the edges.

Step 6: Finish and Serve

Top with the remaining green onions just before serving. Scoop it warm and serve while the cheese is still gooey and the top is bubbling.

Serving and Storing Loaded Twice Baked Potato Casserole

This casserole feeds about 8 people as a side dish, making it a great option for family dinners, holiday meals, and potluck spreads. Serve it hot from the oven for the creamiest texture and the best cheesy finish.

Leftovers store well in an airtight container in the fridge for up to 4 days. Reheat portions in the microwave or warm the full casserole in the oven, covered loosely with foil, until heated through. You can also assemble it ahead of time and refrigerate before baking, which is especially helpful for busy hosting days.
