This homemade cheesy hashbrown casserole is a comforting side dish that everyone loves. Wonderful comforting potato dish loaded with cheddar cheese and creamy sauce. It’s easily prepared without canned soup and baked to a gooey perfection. Make this side dish for every holiday gathering, family dinners, and potlucks.
I was 16 when I first started working at the Cracker Barrel and that’s when I discovered their fabulous baked mac and cheese, broccoli cheddar chicken, and of course, hashbrown casserole.
Years of working there has left me with taste for many of those comforting dishes, which I still make at home. Hashbrown Casserole is definitely one of them. I even make sure to make plenty of this comforting potato side dish for each and every holiday dinner.
Thanksgiving has to have mashed potatoes every time since it’s such a traditional holiday when it comes to food. For other holidays, I like to make different potato sides and preferably the cheesy ones.
Scalloped Potatoes and Hashbrown Casserole are the two that always puts a smile of everyone’s face. It must be the cheese, the cream, and the comfort that fills these potato dishes.
Don’t let the fact that this casserole is prepared with no canned soup make you think that it’s harder to cook. It is just as easy and only takes about 10 extra minutes of preparation time. All the ingredients are easy and something that you most likely already have on hand.
How To Make Hashbrown Casserole Gluten Free:
This casserole is very easily made gluten free. Just make one simple swap of all purpose flour for gluten free all purpose flour.
One thing I’ve noticed about swapping gluten free all purpose flour for regular one in sauces and soups is that it takes just a little more gluten free flour to make it the same thickness.
In most cases, 1 extra tablespoon will do the trick. (Some gluten free brand mixes differ so add 1/2 tablespoon at a time and check the thickness.)
Of course, if you’re making a large amount of soup or sauce, you may need an additional tablespoon.
Can Hashbrown Casserole Be Made Ahead Of Time?
Absolutely. You can prepare the casserole completely up to the baking step and refrigerate overnight. Make sure to cover the prepared casserole dish with plastic wrap before putting it in the fridge.
Take the dish out of the refrigerator about 30 minutes before baking and let it sit on the counter to warm up. Discard the plastic wrap and bake at 350° but add extra 5 minutes or so since the casserole will start out cold.
Store any leftover hashbrown casserole in the refrigerator covered air-tight. You can store it in the original baking dish or transfer it into a food storage container with a lid. Properly stored, hashbrown casserole will last up to 3 days.
