Cheesy Mashed Potato Casserole - the best creamy mashed potatoes baked into a casserole with bacon! Great made ahead as well!

We love potato dishes, like Caramelized Onion Mashed Potatoes or Leftover Mashed Potato Cheddar Ranch Cakes.

Casserole with cheddar and bacon on top.

Let's take boring out of mashed potatoes and turn them into one delicious side dish casserole! I took my best creamy mashed potatoes, stirred in freshly grated cheddar cheese, garlic powder and fresh chopped parsley and baked the mixture in a casserole dish. Topped with crispy bacon and more parsley, this potato bake was gone in a flash! Looking at all of the potato recipes I shared on my blog, I think it's safe to say that these two ingredients happen to be my two toppings for potatoes that I always reach for.

Ingredients:

  • Russet potatoes
  • salt and pepper
  • butter
  • half and half
  • sour cream
  • grated cheese
  • garlic or garlic powder
  • bacon
  • parsley
