Crockpot Cheesy Potato Casserole (With Frozen Hash Browns)

Creamy, cheesy, lots of flavor, and of course, super easy. The slow cooker and a bag of frozen hash browns make this a low-prep side dish that doesn’t need babysitting.

These only need a few ingredients and is easy to throw together. They’re cheesy and creamy and filling, making them a hit with kids and adults.

Ingredients and Tools You’ll Need

Frozen diced hash browns make this so easy, but you can also use frozen shredded hash browns. And if you for some reason want to use fresh potatoes you can (though I don’t). Just peel and dice them yourself. Remember that they might take a bit longer to cook and might need a little extra liquid (like a splash of milk) to keep them creamy.
