Frozen hash browns will not cook in the allotted time and you will end up with crunchy potatoes. Thawing the hash browns allows you to drain any excess moisture otherwise you could end up with a soggy/wet casserole.
Thereof, can hashbrown casserole be frozen before baking?
You can absolutely make hash brown casserole ahead of time and freeze it. In fact, that’s the way I make mine most of the time. You can freeze it before you bake it or after. I find it is best when you make it without baking, freeze it, and then cook it fresh on the day you want to serve it.
Keeping this in view, can I make a hash brown casserole ahead of time?
Can You Make Hashbrown Casserole Ahead of Time? Yes! This is perfect for serving at holiday gatherings or weekend brunch because it’s so easy to make ahead! Simply prepare it without baking it, cover tightly with plastic wrap and refrigerate for up to 3 days.
Can I use fresh shredded potatoes instead of frozen?
You can use fresh potatoes instead of frozen hash browns if you would like. You’ll need to shred the potatoes to be like hash browns, then put the shreds in a bowl of cold water. Then you’ll stir, drain, add more water and repeat a few times to remove the starch from the potatoes.
Already baked hashbrown casserole can be stored in an airtight container in the fridge for 3 days or in the freezer for up to 2 months. To reheat, thaw in the fridge if frozen then cover with foil and bake at 325ºF for 15-20 minutes.
Use one tablespoon of cornstarch per cup of liquid you would like to thicken. Stir out all the lumps. A few minutes before your casserole is done, add it a little at a time until you are happy with the thickness.
How do you get hash browns to stick together? When you mix the shredded potato with salt and flour, the salt will draw a small amount of moisture from the potato. This moisture glues with the flour and keeps the shredded potato in tact.
Cornstarch, potato starch, and chickpea flour are a couple of pantry-friendly ways to thicken soups, stews, and sauces in the slow cooker. Just a tablespoon or two of any — added towards the end of cooking — will thicken sauces especially well.
Whisk in 2/3 cup chicken broth, 1/2 cup milk and 1/4 teaspoon garlic powder, continuing to whisk until it slightly thickens.

As with any other ingredients, it’s recommended to thaw hash browns before cooking. Cooking them frozen will cause the heat to spread unevenly and your hash browns might cook from the outside, while the inside remains frozen. Cooking them frozen might also result in them becoming too mushy and/or watery.
