Years of working at the Cracker Barrel and enjoying all the delicious comforting food drove me to create my own recipes and make it at home. Hashbrown Casserole is definitely one of those dishes. When you have a recipe that beats the restaurant’s, you don’t have a need to go out and get it. You are all set to make it right at home!
This amazing potato side dish is cheesy, creamy, and rich. It features shredded hash brown potatoes mixed with homemade creamy cheese sauce and topped with even more sharp cheddar cheese. Bake it right away or pop it in the refrigerator to bake the next day, either way you will have one of the best side dishes on the table.
Scalloped Potatoes and Hashbrown Casserole are the two sides that we make for a big family dinner. 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.
How To Make Hashbrown Casserole
Step 1: Preheat a pot over medium heat on stove-top and add olive oil. Sauté diced onion until softened and stir in minced garlic. Let garlic sauté for a few seconds, stir, and sprinkle flour all over the onions. Stir well, until onions are well coated with flour.
Step 2: Keep stirring for a few seconds, lower the heat to medium-low, and start slowly pouring in chicken stock, while continuously stirring. The mixture will start to thicken as you are stirring.
Step 3: Keep stirring and pour in milk after. Let the mixture heat through and continue to thicken.
Step 4: Stir in the sour cream, salt, and pepper. Let the mixture cook as you stir slowly for a minute or so.
Step 5: Stir in cheese, one handful at a time, as you stir and let it melt into the sauce. Once the cheese is melted, stir in parsley, and take it off heat.
Step 6: Transfer the hash brown potatoes into a large mixing bowl. Pour the cheese sauce into the bowl with hash browns and carefully stir until completely incorporated. Pour the mixture into the prepared baking dish and make sure it’s spread evenly.
Step 7: Spread more grated cheddar cheese over the top of the casserole. Make sure it’s all spread evenly throughout.
Step 8: Bake the casserole at 350° for 30-35 minutes, until casserole browned and bubbles around the edges. If you wish for the top to get more golden, turn on the broiler for a few seconds.
How To Make It Ahead Of Time?
You can prepare the casserole completely, up to the baking step, and refrigerate overnight. Make sure to cover the prepared casserole dish air-tight with plastic wrap or a fitted lid before putting it in the refrigerator.
When ready to bake, 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 5-7 minutes or so since the casserole will start out cold.
How To Store and Reheat The Casserole
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.
To reheat, you can reheat individual portions in a microwave or the whole casserole in the oven. (Make sure not to overheat it or cheese and cream will start to separate.)
Reheat the whole casserole in the baking dish, in the oven, at 350°. Make sure to let the dish warm up on the counter for about 30 minutes before placing it into the oven. Tent the casserole loosely with a sheet of foil to prevent the top from browning too much.
How To Freeze Hashbrown Casserole?
PRO TIP: If you plan to freeze this casserole, you can prepare it and bake it in an aluminum baking pan. Note that the bake time will be slightly less, about 5 minutes less.
Prepare the casserole and bake it in an aluminum baking dish, per the recipe. Make sure to cool the cooked potato casserole to room temperature before freezing!
Cover the whole pan with plastic or another freezer-friendly air-tight wrap and then, wrap it in a some aluminum foil. Double cover will make sure it is completely air-tight.
Label the pan and freeze it for up to 3 months.
Make sure to thaw it slowly, in the refrigerator, for up to 24 hours.
Variations To Try
This is a great potato side dish but you can easily add some protein to it. You can add diced ham or crispy cooked bacon right into the hashbrown mixture. It’s also a nice recipe for using up leftover turkey meat!
Add some extra flavor with chopped chives, scallions, and/or parsley.
Make it spicy by adding jalapenos or other chili peppers.

Notes
- Gluten Free*: This casserole is very easily made gluten free. Just substitute all purpose flour for gluten free all purpose flour. Note that sometimes it takes just a little more gluten free flour to make it the same thickness as regular. (Depending on the brand.) In most cases, 1/2-1 extra tablespoon will do the trick.
- To Make It In The Crock Pot: Prepare the casserole as instructed in the recipe up to the step of spreading it in the baking dish. Spread the cheesy potato mixture in the Crock Pot, cover with the lid, and cook for 2-3 hours on HIGH or for 4-4.5 hours on LOW. Spread the grated cheese on top of the casserole during the last 30 minutes of cook time.
- Storing: 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.
- Shredded Hash Brown Potatoes – hash brown potatoes usually come frozen so make sure to thaw the potatoes first. Best way to do that is to thaw them overnight or for up to 24 hours in the refrigerator.

I’ve made and enjoyed this recipe several times now. I am making it for a friend who is gluten intolerant and I was wondering if I could use cornstarch in place of flour for thickening? Thank you!
LyubaB says
Don’t use cornstarch just substitute all-purpose flour for gluten-free all-purpose flour. Note that sometimes it takes just a little more gluten-free flour to make it the same thickness as regular. (Depending on the brand.) In most cases, 1/2-1 extra tablespoon will do the trick. I hope this helps!

I followed the recipe but used shredded sweet potatoes, made up one cup herb ox sodium free chicken bouillon, only used 8 oz of Daisy sour cream, and a half a brick of Philly cream cheese, didn’t have any cheddar cheese in the house but I had a 14 oz bag of four cheese Mexican blend three quarters of the bag mixed in with the potato mixture the last quarter of the bag used to top off the casserole also used 3 oz of Smithfield bacon bits to top off the casserole.
