Twice Baked Potato Casserole Recipe is a super creamy casserole made with tender mashed potatoes, loads of cheddar cheese, and delicious crispy bacon.
Loaded Potato Casserole
This side dish is worth the time to make it with sour cream, green onion topping, and can easily be loaded with more of your favorite potato toppings – talk about a comfort food!
Twice baked potatoes are so aptly named because they are cooked twice – leaving them savory, soft, and creamy.
They key to this casserole is to simply pre-prep your potatoes before adding flavorful ingredients like butter, sour cream, seasoning and loads of cheese, and then piling high with the good stuff- bacon!
I love a regular loaded baked potato, but this mashed potato casserole is so filling that its a meal in and of itself!

Here is what you need to gather to get started:

Simple Casserole Variations: Feel free to add a layer of seasoned beef on the bottom of this loaded baked potato casserole to not only add some protein, but turn this ultimate side dish into a main dish (think loaded baked potato Shepard’s pie!)
Prep Potatoes in Microwave
Before getting started, you need to prep the potatoes so they are already soft and scoop-able.
You can boil, instant pot, oven bake or microwave -whatever you are most comfortable with.
Personally, I wash/scrub potatoes, cut them in half, and poke holes in the skin with a fork.
Place on a microwave safe plate. I microwave for 5 minutes and then flip over and continue to microwave for an additional five minutes or until soft.
My dad has this trick where he pokes holes in them and puts them in a zip lock baggie, leaving just the edge open.
He does 1-2 potatoes at a time for about 8 minutes, until you can run a knife into them. Again, they get really hot so no matter how you prep your potatoes, make sure you be careful.
If you are pressed for time, you CAN use instant potatoes or frozen steamed potatoes.
They do not have the same homemade taste as doing the russet potatoes by hand, but its still a solid dish.
How to make Twice Baked Potato Casserole
Preheat oven to 400 and spray a 2-1/2 quart casserole dish with nonstick cooking spray and set aside.
Prep your potatoes (see note on potatoes).
Scoop the insides out of the potato and place into a mixing bowl.
Discard the potato skins.
Add butter, sour cream, cream, one cup of cheese and spices. Mix well.
Spoon potato casserole into prepared dish. Sprinkle with remaining shredded cheese and top with bacon.
NOTE ABOUT BACON: When it comes to using bacon as as topping, it can get frustrating to get the right crisp.
I now use my Ninja Foodi to Air Fry my bacon in about 10 minutes, which allows me to really use a lot of extra bacon without having to stand over a hot splattering skillet.
If you have never made bacon that way, I recommend it!!!
Bake baked potato casserole for 10-15 minutes or until heated through and bubbly around the edges.
