You know how there are certain scents or food that you would always associate with certain events or festivities? Well, this cheesy hash brown casserole is one that reminds me a lot of the holidays because my mother-in-law would make this without fail. And I just love it so much!
It’s such a simple and easy recipe that takes only 15 minutes of prep time, and then you can just leave it to bake in the oven!
Panko-Parmesan Topped Hash Brown Casserole
For this version, I mixed together frozen hash browns with a creamy, cheesy sauce and spread into a dish, then topped it off with cheddar, parmesan, panko and butter. Some people use cornflakes as a topping, but I prefer panko for that crunchy bite.
With all the crispy, cheesy, buttery goodness, it’s definitely up there as one of my comfort food.

NOTES FOR CHEESY HASH BROWN CASSEROLE
- Crust layer – Traditionally, butter and cornflakes is used for the top crust layer but I like using panko parmesan instead. Either will work.
- Make ahead – You can make this ahead a day before and store in the fridge, then pop it in the oven the next day. Just make sure to add the panko crumbs before baking to prevent it from getting soggy.
- Storage – Any leftovers can also be stored in the freezer! You can pack them up in individual servings to make it easier when reheating.

- Sweet Potato Mash With Miso Butter
- Salmon Crab Stick Sushi Bake
