Under swirling steam and a rich buttery smell, this Hashbrown Casserole Recipe first caught my attention in my grandma’s kitchen. On my maiden test, I noticed the potatoes clumped—so I learned to spread them out evenly. By my third bake, that glossy, bubbling top and golden edges were exactly what I sought.

A Little Background
My first encounter with this version came when I craved something hearty on a rainy Sunday. Originating in Midwestern potlucks, the roots of this dish trace back to simple farm kitchens where shredded potatoes met creamy binders. During my very first trial, I learned the hard way that thawed hash browns must be drained well to avoid a watery bake.
Key Ingredients for Hashbrown Casserole Recipe
- Shredded Hash Browns (30 oz): Provides the base—ensure fully thawed and patted dry to prevent sogginess.
- Cream of Chicken Soup (10.5 oz): Offers savory creaminess; substitute with cream of mushroom for a vegetarian twist.
- Sour Cream (2 cups): Adds tang and silkiness—full fat keeps it rich, but light works in a pinch.
- Cheddar Cheese (2 cups, divided): Sharp cheddar melts beautifully; reserve ½ cup for that glossy finish.
- Corn Flakes (1½ cups, crushed): Creates a golden, crunchy topping—try crushed panko for a crispier variation.
How to Make Hashbrown Casserole Recipe
- Preheat your oven to 350°F and butter a 9×13-inch baking dish until it glistens.
- Combine 30 oz thawed hash browns, ½ cup melted butter, 1 minced medium onion, 10.5 oz cream of chicken soup, 2 cups sour cream, 1½ cups shredded cheddar, 1 tsp salt, and ¼ tsp pepper in a large bowl—mix until everything is coated in a creamy, uniform blend.
- Spread the mixture into the prepared dish, smoothing the top so it bakes evenly without dry spots.
- In a small bowl, stir together 2 Tbsp melted butter and 1½ cups crushed corn flakes; sprinkle this golden layer over the casserole.
- Bake for 45 minutes, or until the corn flake crust is golden and you see soft bubbling around the edges.
- Remove from oven, sprinkle the remaining ½ cup cheddar over the top, then bake 5 minutes more until the cheese is melted and glossy.
- Allow the casserole to rest 5 minutes before serving, giving the center time to set for clean slices.
Pro Tips & Troubleshooting
- During testing, I found that pressing down lightly on the hash browns before baking helps prevent shifting cheese pockets.
- If the topping browns too quickly, tent loosely with foil after 30 minutes and continue baking.
- Swap half the cheddar for Monterey Jack and add a pinch of cayenne for a Tex-Mex twist.
- To halve the recipe, use an 8×8″ dish and reduce bake time by about 10 minutes—watch for bubbling.
Storage & Make-Ahead Guide
Store leftovers in an airtight container in the refrigerator for up to 4 days—reheat at 350°F until piping hot (165°F internal temp). To freeze, cool fully, wrap tightly, and freeze for up to 2 months; thaw overnight before reheating. Note from my kitchen: next-day casseroles firm up beautifully, but a splash of milk before reheating keeps them creamy.
Serving Suggestions
Pair this casserole with braised greens for a Southern-style feast, or serve alongside grilled chicken and a crisp garden salad to balance the richness.
Frequently Asked Questions
- Can I use fresh potatoes instead of frozen hash browns? Yes—grate two pounds of russet potatoes, rinse and squeeze out excess water, then proceed as directed.

- What’s the best way to reheat leftover hash brown casserole? Cover with foil and bake at 350°F for 15–20 minutes, or microwave individual portions until hot throughout.
