This casserole is such a crowd pleaser, perfect for holiday dinners, family get-togethers or anytime you are needing a delicious potato fix. Even better, this casserole recipe can be made a few days ahead of time which makes it a perfect recipe to serve for Thanksgiving when the day is already busy. See some make ahead tips below.
No fancy ingredients for this casserole, simple and delicious.
Russet Potatoes: Russets are great for this recipe because they are starchy which holds up well. Yukon Gold would work well too. Avoid red or new potatoes, they tend to turn out gluey.
Bacon: What twice baked potato isn’t complete without bacon?
Hiland Dairy Butter: Hiland butter gives these potatoes major flavor
Hiland Dairy Whole Milk: I use whole milk for this recipe, I feel like it makes the potatoes creamier and adds a bit more flavor.
Hiland Dairy Sour Cream: Hiland Sour Cream is the one to use if you want the creamiest potatoes with just a slight bit of tang added in. The best.
Shredded Cheddar Cheese: Twice Baked Potatoes gotta have cheese, both throughout and on top. The more the better.

Step One: Preheat the oven to 400 degrees. Place the potatoes on a baking sheet, drizzle with oil and rub into each potato. Bake for 40 minutes or until the potatoes can be sliced easily.
Step Two: Cook the bacon until it’s done but not crisp. Transfer to a paper towel lined plate and set aside. Measure out the butter, milk and sour cream and set out so they are room temp prior to mixing with potatoes.
