The best loaded twice baked potato casserole recipe

This is the easiest, most delicious twice-baked potato casserole made with simple ingredients and topped with lots of cheese!

This recipe, like so many others here on my blog, is a result of wanting a delicious meal but not having the time or energy to do a ton of dishes and get really fancy.  Twice-baked potatoes are a favorite in my home and were requested one night recently when the baby was really fussy and I only had one free hand.  I knew scooping the centers out of the potato skins and mixing up filling wasn’t going to happen, so I improvised, smashed my baked potatoes up with a fork, topped them with the fixins’, put them back in the oven, and served them up hot.  They were a hit!

Turning anything and everything into casserole form is a Midwest specialty I’m glad to say I’ve mastered lol.  This is such an easy casserole dish to throw together on busy nights or to bring to gatherings. I’ve made it half a dozen times since and they’ve earned a permanent spot on our menu as one of our favorite recipes.  I hope you enjoy them too!

Why You’ll Love This Recipe

  • This is a one-pot, or shall I say – one-skillet meal.  So you won’t have a ton of dishes, just a skillet, a knife, and a fork is all you need!  For this reason alone, this is one of my favorite potato recipes.
  • You can modify this recipe to be as simple as you want or you can layer on as many of your favorite potato toppings as you can think of like sour cream, green onions, bacon bits, etc.
  • This twice-baked potato casserole recipe is really good leftover, so if you make a big skillet full you’ll have a side dish that should last a few meals.
