If loving potatoes is wrong, I don’t want to be right. Bake them, mash them, whip them with butter, or blanket them in cheese—I’m in. And this Loaded Twice Baked Potato Casserole takes everything we adore about classic twice baked potatoes and turns it into one big, bubbling, golden-topped dish of comfort.
Imagine fluffy baked russet potatoes blended with creamy butter, tangy sour cream, rich cream cheese, sharp cheddar, and crispy bacon. Now imagine all of that baked together in one casserole dish until hot and melty. That’s exactly what you’re getting here. It’s hearty, indulgent, and made to feed a crowd.
This is the kind of side dish that shows up at potlucks and steals the spotlight. It belongs on holiday tables next to roasted turkey and glazed ham. And honestly? It’s just as welcome on a random Tuesday night when you need something warm and satisfying.
Easy Recipe for Loaded Twice Baked Potato Casserole
Traditional twice baked potatoes are delicious, but let’s be honest—they take time. Bake the potatoes, scoop them out, mix the filling, refill the skins, and bake again. It’s worth it, but it’s work.
This casserole skips the fussy part and keeps all the flavor.
Instead of refilling each potato shell, we bake the potatoes until fork-tender, scoop out the fluffy centers, and mix them with all the good stuff in one large bowl. Everything gets spread into a baking dish, topped with more cheese and bacon, and baked again until bubbly and golden.
The result? A creamy, cheesy, bacon-studded potato casserole with all the decadence of twice baked potatoes—without the extra steps.

Ingredient Highlights
This casserole keeps things simple with everyday ingredients:
Russet Potatoes
Russets are ideal because they’re starchy and fluffy when baked. They mash beautifully and create that classic twice baked texture.
Butter, Sour Cream & Cream Cheese
This trio builds the creamy base. Butter adds richness, sour cream gives tang, and cream cheese creates that ultra-smooth finish.
Cheddar Cheese
Sharp cheddar brings bold flavor. It melts perfectly into the potato mixture and forms a golden layer on top.
Bacon
Crispy bacon adds smoky depth and crunch. Half goes inside the casserole, and half gets sprinkled on top.
Milk
A little milk loosens the mixture and keeps it from feeling too dense.
Seasonings
Garlic powder, salt, and freshly cracked black pepper keep the flavors classic and balanced.
How to Make Loaded Twice Baked Potato Casserole
This recipe is straightforward and beginner-friendly.
1. Bake the Potatoes and Bacon
Start by preheating your oven to 400°F. Wash and dry the potatoes, pierce them with a fork, and brush them lightly with oil. This helps the skins crisp up.
Place them on a parchment-lined baking sheet.
On a separate lined tray, arrange the bacon slices. Bake the bacon for about 15–20 minutes until crispy, then remove and let cool before crumbling.
Continue baking the potatoes for about 40 more minutes, or until they’re fork-tender. Larger potatoes may need up to an hour total.
2. Prepare the Filling
Lower the oven temperature to 375°F.
Once the potatoes are cool enough to handle, cut three of them in half lengthwise and scoop out the flesh into a large bowl. You can save the skins for another use. Add the remaining three potatoes (chopped or scooped), half the crumbled bacon, softened butter, sour cream, milk, cream cheese, 1 cup of shredded cheddar, garlic powder, salt, and black pepper.
Mash everything together until creamy and well combined. The mixture should be smooth but still have some texture.
3. Assemble and Bake
Lightly grease a 9×13-inch baking dish with nonstick spray. Spread the potato mixture evenly into the dish.
Top with the remaining cheddar cheese and the rest of the crumbled bacon.
Bake uncovered for 25 minutes, or until the cheese is melted and bubbly.
Remove from the oven and sprinkle sliced green onions over the top before serving.
Recipe Tips & Suggestions
- Adjust baking time as needed. Large russet potatoes can take up to an hour to become fork-tender. Smaller ones will cook faster.
- Add extra seasoning. Paprika, onion powder, dried chives, Cajun seasoning, or a pinch of cayenne can elevate the flavor.
- Don’t waste the skins. Chop them and mix them into the casserole for added texture, or crisp them in an air fryer at 400°F for 5–10 minutes.
- Make it ahead. Assemble the casserole, cover, and refrigerate. Bake just before serving.
- Halve the recipe easily. Cooking for fewer people? Use half the ingredients and an 8×8 baking dish.
- Preheat the Oven
Preheat your oven to 400°F (200°C). Line two baking sheets with parchment paper. - Prepare the Potatoes
Wash and dry the potatoes thoroughly. Pierce each potato several times with a fork. Brush them evenly with vegetable oil and place them on one of the prepared baking sheets. - Bake the Bacon
Lay the bacon slices flat on the second baking sheet. Place both trays in the oven.
Bake the bacon for 15–20 minutes, or until crispy. Remove it from the oven, allow it to cool, then crumble. Set aside. - Finish Baking the Potatoes
Continue baking the potatoes for about 40 additional minutes, or until they are fork-tender. Larger potatoes may take up to 60 minutes total. Remove from the oven and let cool slightly. - Lower Oven Temperature
Reduce the oven temperature to 375°F (190°C). - Prepare the Filling
Once cool enough to handle, cut three potatoes in half lengthwise and scoop out the flesh into a large mixing bowl. Reserve the skins for another use if desired.
Chop or scoop the remaining three potatoes and add them to the bowl.
Notes
- Potato Size Matters: Cooking time will vary depending on the size of your potatoes. Large russets can take up to one hour to become fully tender.
- Dairy Substitutions: You may substitute milk with half-and-half or heavy cream for an even richer casserole.
- Cheese Variations: Try Monterey Jack, Colby, mozzarella, or a blend of cheeses for a different flavor profile.
- Extra Flavor Boost: Add paprika, onion powder, dried herbs, Cajun seasoning, or a pinch of cayenne for a subtle kick.
- Using the Skins: Chop the reserved skins and stir them into the casserole for added texture, or crisp them in an air fryer at 400°F for 5–10 minutes.
- Make Ahead Option: Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. Add 5–10 extra minutes to the baking time if starting cold.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave until warmed through.
