How to make twice baked potato casserole:

This recipe is a long one, so hang in there. I promise it will be worth the wait!

First, preheat your oven to 425° F, and grease a 9 x 13-inch casserole dish. Next, wash the potatoes, poke a few holes in them, and coat them with oil.

Baking potatoes on a baking sheet.

Place the taters on a baking sheet and put them into the oven to cook for about forty minutes.

While the they bake, pan fry your bacon, pat it dry, and crumble it. Once the taters are done baking, remove them from the oven and let them cool until you can handle them.

Butter, cheese, and other ingredients in a bowl for mashing.

This would be a good time to shred your cheddar cheese. Additionally, you can reduce the oven temperature to 350° F.

Then, when the taters have cooled, dice them up. You can skin them if you like, but we left the skins on.

Potatoes and sour cream mixture combined in a bowl.

Grab a large mixing bowl and use a potato masher or hand mixer to combine one cup of the cheese with the sour cream, butter, milk, diced potatoes, and half of the bacon.

Your twice baked potato casserole mixture should look similar to the picture above.

After the ingredients have been combined, transfer them to a nine (9) by thirteen (13) inch baking dish. Use a rubber spatula to evenly spread out the mixture.

Top the casserole with the remaining cheese and bacon. Afterward, place the casserole dish into the oven to bake.

Bacon and shredded cheddar sprinkled over the casserole.

Let it bake (uncovered) for about twenty-five minutes, or until all the cheese has melted.

That’s it, your twice baked potato casserole is done! Kim and I hope you enjoy the dish and we wish you all the best 🙂
