Twice Baked Potato Casserole has all the ingredients from a twice-baked potato in casserole form. You get the potatoes, cheese, bacon, sour cream and more in this comfort food.
Clean and dry potatoes, then rub them with olive or canola oil. Place them on a baking sheet or right onto your oven rack. Bake until fork tender (about 1 hour).
Once potatoes are cooked, lower temperature of oven to 350 degrees. Peel the potatoes, if you prefer, or keep the skin on. Mash 4-6 potatoes and cut the other 2-4 potatoes into cubes, placing them into a large bowl.
While potatoes are still warm, add in other ingredients, reserving about 1 cup of cheese, some bacon, and green onions for the top.
Stir together and place into a greased (sprayed) 9×13″ baking dish. Top with cheese and bacon, still reserving green onions for the top.
Bake for 20-25 minutes, then top with the rest of the green onions and enjoy!
