Loaded Twice Baked Potato Casserole takes everything people love about a classic twice baked potato and turns it into a bubbling, cheesy, family-style dish. It has fluffy potatoes, creamy sour cream, melted cheddar, smoky bacon, and fresh green onions baked together until the top is golden and irresistible.


This is the kind of comfort food casserole that works for holidays, potlucks, Sunday dinner, game day, or a cozy weeknight meal. You get all the flavor of stuffed baked potatoes without filling individual potato skins, which makes it easier to prep, serve, and share.
Why You’ll Love This Loaded Twice Baked Potato Casserole
This casserole is rich, creamy, cheesy, and packed with familiar loaded baked potato flavor. It feels special enough for a holiday side dish but simple enough to make when you need a comforting dinner side that everyone will actually eat.
It is also flexible. You can make it extra cheesy, add more bacon, keep the green onions mild, or turn it into a heartier main dish with chicken or ham. The texture is what makes it so good: soft mashed potatoes underneath, melted cheese on top, and crispy bacon in every bite.
What Kind of Potatoes Work Best for Loaded Twice Baked Potato Casserole?
Russet potatoes are the best choice because they bake up fluffy and mash beautifully. Their starchy texture helps the casserole stay light instead of gummy, which is exactly what you want for a twice baked potato-style dish.
Yukon Gold potatoes can also work if you prefer a creamier, naturally buttery texture. They will create a denser casserole, but the flavor is excellent. Avoid waxy potatoes like red potatoes unless you want a chunkier, less fluffy result.
Ingredients

This loaded potato casserole uses simple ingredients, but each one helps build that classic twice baked flavor. Choose good melting cheese, crisp bacon, and tender baked potatoes for the best texture.
- Russet potatoes — The fluffy base of the casserole and the best choice for a classic twice baked potato texture.
- Butter — Adds richness and helps the potatoes taste smooth and comforting.
- Sour cream — Gives the casserole tang, creaminess, and that loaded baked potato flavor.
- Milk — Loosens the potatoes so the filling stays soft instead of dry.
- Cream cheese — Adds a velvety texture and helps the casserole hold together.
- Sharp cheddar cheese — Melts into the potatoes and creates the golden cheesy topping.
- Cooked bacon — Brings smoky, salty crunch that makes the casserole taste fully loaded.
- Green onions — Add fresh flavor and a mild onion bite that balances the richness.
- Garlic powder — Adds savory depth without overpowering the potatoes.
- Salt — Brings out the flavor of the potatoes, cheese, and bacon.
- Black pepper — Adds a gentle warmth and keeps the casserole from tasting flat.
- Optional paprika — Adds color and a light smoky note on top.
How To Make the Loaded Twice Baked Potato Casserole
The key is to bake the potatoes until very tender, scoop and mash them while warm, then fold in the creamy ingredients without overmixing. Once everything is layered with cheese and bacon, the oven finishes the casserole with a golden, bubbly top.
Step 1: Bake the Potatoes
Scrub the potatoes well, dry them, and pierce them with a fork. Bake them until the centers are soft and the skins feel slightly crisp. Let them cool just enough to handle, then slice them open and scoop the potato flesh into a large mixing bowl.
Step 2: Mash the Potato Filling
Add butter, cream cheese, sour cream, milk, garlic powder, salt, and black pepper to the warm potatoes. Mash until creamy but not gluey. A few small potato pieces are perfectly fine because they give the casserole a homemade texture.
Step 3: Fold in the Loaded Ingredients
Stir in part of the cheddar cheese, part of the cooked bacon, and some sliced green onions. Fold gently so the potatoes stay fluffy and the add-ins are spread evenly throughout the casserole.
Step 4: Assemble the Casserole
Spread the potato mixture into a greased baking dish. Smooth the top, then sprinkle with the remaining cheddar cheese and bacon. Add a little paprika if you want extra color.
Step 5: Bake Until Golden and Bubbly
Bake the casserole until hot in the center and melted on top. The edges should look slightly golden, and the cheese should be fully melted. Let it rest for a few minutes before serving so each scoop holds together better.
Step 6: Finish with Green Onions
Scatter fresh green onions over the top right before serving. This keeps their flavor bright and gives the casserole a fresh pop against the rich cheese and bacon.
How to Serve Loaded Twice Baked Potato Casserole
Loaded Twice Baked Potato Casserole feeds about 8 people as a side dish, or 6 people if served in larger portions. It is hearty, so it pairs beautifully with roasted chicken, grilled steak, baked ham, turkey, barbecue, or a simple green salad.
For a holiday table, serve it in a warm baking dish with extra green onions and bacon on top. For a casual dinner, it can be the cozy side next to chicken tenders, burgers, meatloaf, or pork chops. You can even turn leftovers into a quick lunch by adding chopped chicken or steamed broccoli.
How to Store Loaded Twice Baked Potato Casserole
Let the casserole cool completely before storing. Transfer leftovers to an airtight container or cover the baking dish tightly with foil or plastic wrap. Refrigerate for up to 4 days.
To reheat, cover the casserole with foil and warm it in the oven until heated through. If reheating a single serving, the microwave works well; add a small splash of milk before heating if the potatoes seem thick. For the best texture, stir gently halfway through reheating.
You can also freeze this casserole, though the texture may become slightly softer after thawing because of the dairy. Freeze it tightly wrapped for up to 2 months. Thaw overnight in the refrigerator, then bake covered until hot. Remove the foil near the end to refresh the cheesy top.
Frequently Asked Questions
Can I make Loaded Twice Baked Potato Casserole ahead of time?
Yes, this casserole is a great make-ahead dish. Assemble it up to the baking step, cover it tightly, and refrigerate it for up to 24 hours. When ready to bake, let it sit at room temperature while the oven preheats, then bake until the center is hot and the cheese is melted.
Can I use leftover mashed potatoes?
You can use leftover mashed potatoes, but the flavor and texture will be slightly different from baked potatoes. If your mashed potatoes are already very creamy, reduce the milk and sour cream so the casserole does not become loose. Fold in the cheese, bacon, and green onions, then bake until bubbly.
How do I keep the casserole from turning gummy?
Avoid overmixing the potatoes. Mash them while warm, add the creamy ingredients, and mix only until everything is combined. A potato masher works better than a food processor because high-speed mixing can make potatoes sticky.
Can I add protein to make it a main dish?
Yes. Chopped cooked chicken, diced ham, ground beef, or turkey can turn this into a filling dinner casserole. Add the protein when folding in the cheese and bacon so it spreads evenly through the potatoes.
What cheese melts best in this casserole?
Sharp cheddar is the classic choice because it melts well and gives strong flavor. You can also use Monterey Jack, Colby Jack, pepper jack, or a cheddar blend. For the best melt, shred the cheese yourself instead of using pre-shredded cheese.
