How to Make Twice Baked Potato Casserole
Here is a brief overview of how to make twice baked potatoes casserole. For the full recipe including all measurements, scroll to the recipe card at the bottom of the page.
- Bake the potatoes. Place the whole potatoes on a baking sheet and bake them until you can easily slice through one.
- Scoop out the potatoes. At the end of baking, remove the potatoes cool and slice them in half. Scoop out the insides of each half and put them into a large bowl. (Discard the skins or save them to make Jalapeno Popper Potato Skins.)
- Make the filling. Add the butter, sour cream, and milk to the potatoes. Beat until smooth. Stir in the salt, pepper, some of the cooked bacon, some cheddar cheese, and green onions.
- Bake. Spread the mixture into the prepared baking dish and top with the remaining cheese and bacon. Bake until the cheese is melted.
Best Potatoes to Use
Russet potatoes are what I recommend for this recipe or traditional twice baked potatoes. If you are living in the UK, the closest potato to the russet is a white potato.
Bacon adds so much flavor to this twice baked potato casserole recipe, so cooking it well is important. I prefer to dice up the bacon and then cook it in a cast iron pan just until it begins to turn crisp. Remove it from the pan with a slotted spoon and transfer it to a paper towel lined plate.
You could also cook your bacon in the air fryer for a super easy cleanup. Cook it whole and then dice it after it is cooked.
This is a great casserole recipe to make ahead for an easy weeknight dinner. Follow the recipe right up to placing the potato mixture in the baking dish and covering with remaining bacon and cheese. Cover with foil and refrigerate for up to 24 hours, or place in a freezer safe pan, cover with foil twice and freeze. Freeze for up to three months. When you are ready to bake it, remove it from the freezer and bake until heating through and the cheese is melted.
When freezing casseroles, be cautious when using glass or ceramic baking pans as they are at risk of shattering. You are better off using an aluminum baking dish if you want to freeze it.
