How To Make the Loaded Twice Baked Potato Casserole

Step 1: Prepare the Potatoes

Peel the russet potatoes and cut them into evenly sized chunks. Place them in a large pot, cover with cold salted water, and bring to a boil. Cook until fork tender, about 15 to 20 minutes.

Step 2: Cook the Bacon and Prep the Pan

While the potatoes cook, fry the bacon until crisp, then transfer it to a paper towel lined plate and crumble once cool. Grease a 9×13-inch baking dish and preheat the oven to 375°F.

Step 3: Mash the Filling

Drain the potatoes well and return them to the warm pot for a minute so excess moisture can evaporate. Add the butter, sour cream, milk, garlic powder, onion powder, salt, and black pepper, then mash until creamy and mostly smooth.

Step 4: Add the Loaded Mix-Ins

Fold in 1 1/2 cups of the cheddar cheese, most of the crumbled bacon, and most of the green onions. Stir gently so the mix-ins are evenly distributed without overworking the potatoes.

Step 5: Fill the Casserole Dish

Spread the mashed potato mixture into the prepared baking dish. Smooth the top with a spoon or spatula so the casserole bakes evenly.

Step 6: Add the Topping

Sprinkle the remaining 1/2 cup cheddar cheese over the top, followed by the reserved bacon pieces. This creates that irresistible cheesy, savory crust.

Step 7: Bake Until Hot and Bubbly

Bake uncovered for 20 to 25 minutes, or until the casserole is heated through and the cheese on top is melted and lightly golden around the edges.

Step 8: Finish and Serve

Remove the dish from the oven and let it rest for 5 minutes. Top with the remaining green onions and chopped chives, then serve warm.

Frequently Asked Questions

Can I make Loaded Twice Baked Potato Casserole ahead of time?

Yes. You can assemble the casserole up to one day in advance, cover it tightly, and refrigerate it before baking. Add a few extra minutes to the oven time if it goes into the oven cold.

What potatoes work best for this casserole?

Russet potatoes are the best choice because they mash up light and fluffy. Yukon Gold potatoes also work if you want a creamier texture.

Can I use turkey bacon or leave the bacon out?

Absolutely. Turkey bacon works well, and you can skip the bacon entirely for a vegetarian version. Adding a little smoked paprika can help replace some of that smoky flavor.

How do I keep the casserole from getting gluey?

Do not overmix the potatoes once they are mashed. Stir just until the ingredients are combined so the texture stays soft and fluffy.

Can I add cream cheese to the filling?

Yes. A few ounces of softened cream cheese can make the filling even richer and tangier. Just reduce the milk slightly if the mixture becomes too loose.

What can I put on top besides cheddar?

Monterey Jack, Colby, mozzarella, or a cheddar blend all work nicely. You can also add extra chives or a spoonful of sour cream when serving.
