Food History
Casseroles became a household staple in the mid-20th century when convenience foods like frozen potatoes and canned soups gained popularity. The idea of a cheesy potato bake likely stems from traditional potato gratins, but this version is a uniquely American creation.
Hash brown casseroles became especially popular in the Midwest and South, where they are often served at church gatherings and family reunions. Today, variations of this dish can be found across the country, often with personal twists on the ingredients and toppings.

Recipe Discussion
This baked potato casserole is all about creamy, cheesy comfort. Frozen hash browns paired with a rich mixture of sour cream, cream of chicken soup, and cheddar cheese make it a foolproof dish that delivers on flavor.
The melted butter gives the casserole extra richness, while the chopped onions add a bit of bite. The crunchy cornflake topping adds texture and absorbs just enough butter to give it a slightly crisp buttery finish. It’s the perfect contrast to the creamy base.
Preparation Tips
- Use frozen hash browns for convenience – No need to peel or shred potatoes.
- Shred your own cheese – Pre-shredded cheese has anti-caking agents that affect melting.
- Let the casserole rest before serving – This helps the flavors meld and makes slicing easier.
- Add protein for a full meal – Mix in cooked bacon, ham, or shredded chicken.
- Make it vegetarian – Swap out the cream of chicken soup for cream of mushroom or a homemade roux.
