Why You’ll Love This Loaded Baked Potato Casserole Recipe

We all know and love twice-baked potatoes, but MAN are they a lot of work. This casserole simplifies things into a hearty side dish with all of your favorite potato toppings.

  • Simplified twice baked potato – All of the best parts of twice baked potatoes are simplified into this delicious casserole form with almost no prep time. It’s sure to be a huge hit with your family.
  • Use up leftovers – This casserole is a great way to use up leftover mashed potatoes, too. In fact, my favorite time to make it is after the holidays when I’m sure to have lots of leftovers.
  • Easy side dish – If you are a potato lover like me and you are looking for an easy side dish for twice baked potato casserole, look no further! 

Ingredients

The simple ingredients of this loaded baked potato casserole create a magnificent dish!

  • Mashed potatoes – You can always make your own mashed potatoes (I would use russet potatoes or red potatoes) or even buy them premade at the store. Rather than using a potato masher, I’d use an electric mixer. We want creamy mashed potatoes, not chunky. And make sure the potato skins are removed.
  • Sharp cheddar cheese – For extra cheesy potatoes, we will be adding this directly to the potato mixture and also on top of the casserole too.
  • Sour cream – A lot of recipes call for cream cheese, but with all the sour cream and cheddar cheese, I find my twice-baked potato casserole to be just right.
  • Milk – Some recipes use heavy cream, but I find that milk works best. It thins this potato mixture down to exactly the right consistency that we need for this loaded potato casserole.
  • Butter – As always, I choose to use unsalted butter when cooking. That way I am able to control the amount of salt that goes into this perfect side dish.
  • Salt and pepper – I always use fine sea salt and freshly ground pepper for this casserole. If using salted butter, be sure to omit the salt all together.
  • Garlic powder – With all the goodness of the cheese, the only seasoning we really need for this easy casserole dish is garlic powder.
  • Bacon – You can’t have a twice-baked potato casserole recipe without crispy bacon! I like to crumble mine on top, but you could throw into the potato mixture as well.
  • Scallions – Sometimes called green onions, these babies not only add a little crunch and flavor, but they also add a pretty green color to the finished dish.
