“I have made hadhbrown casserole for years with COC soup. Thisi is the best recipe for this casserole and the best way to prepare as the recipe states.” ~Barbara ⭐⭐⭐⭐⭐
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!
Scalloped potatoes and hashbrown casserole are the two potato sides that I 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. (Okay, I also frequent my loaded cheesy potato casserole as well.)
Tips For Making Hashbrown Casserole
- Do thaw frozen hashbrowns: 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.
- Successful smooth cheese sauce: coat sauteed onions in flour evenly. Pour the liquids in slowly AS you continuously but slowly stir! The mixture will start to thicken as you are slowly stirring. (Feel free to use a whisk if that is more comfortable for you.)
- Keep the temperature below medium! Never have the heat too high when making any kind of creamy cheese sauce. Medium to start and the lower to medium low after adding liquids.
- Add cheese one handful at a time: slowly stir as you add the cheese one handful at a time. This will help the cheese melt and incorporate into the sauce evenly.
- Take off heat as soon as cheese is melted.
- Be gentle mixing hashbrowns and cheese sauce. Don’t overmix but make sure it’s mixed evenly.
- If you’re noticing that the top is getting browned too fast, you can loosely place a sheet of aluminum foil on top of the baking dish. This will deflect direct heat from the cheese topping.
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°F. 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.

Hashbrown Casserole Recipe
Ingredients
- 30 oz frozen shredded hash brown potatoes thawed
- 2 tbsp olive oil
- 1 yellow onion diced
- 3 large garlic cloves minced
- 1/4 cup all purpose flour*
- 2 cups whole milk (can use reduced fat if needed)
- 1 cup chicken stock
- 1 cup sour cream
- 8 oz shredded sharp cheddar cheese
- 1 1/2 tbsp minced parsley (can use dried parsley if needed)
- salt
- fresh cracked black pepper
- 1 cup shredded sharp cheddar cheese topping
Instructions
- Preheat the oven to 350°F and grease a 9×13 casserole baking dish.
- Preheat medium pot over medium heat on stove-top.
- Add oil, heat it through, and add diced onions. Sauté onions until they start to brown.
- Smash and mince garlic and add it to the onions. Stir and sauté until fragrant, just a few seconds.
- Sprinkle flour over the onions and stir well. Stir for a few seconds and start slowly pouring in chicken stock, while stirring. Pour in milk after that while stirring as well.
- Lower the heat to medium-low. Let the mixture heat through and start to thicken. Make sure to stir often.
- Stir in sour cream, salt, and pepper. (You may need to use a whisk to help incorporate the sour cream.) Let the mixture cook for about a minute.
- Stir in cheese one handful at a time. Stir in as it melts and taste to make sure you have enough seasoning. Once cheese is melted, stir in parsley and take the pot off heat.
- Mix hash brown potatoes and cheese sauce in a large bowl and spread the mixture in the prepared casserole dish. Make sure it's all spread evenly throughout.
- Spread some more cheese on top and bake for 30-35 minutes, until casserole browned and bubbles around the edges. If you would like to brown the top a little more, turn on the broiler for a few seconds.

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.
- Frozen 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.
- Flavor Variations and Additions: you can easily add some protein to it, like 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.

These potatoes were amazing!!!
Thanks, Sean! So glad you liked them!
Question, can you make with the country “cubed” potatoes? Would I bake to crisp up?
Hey Connie! I actually have a recipe that is very similar to this one but using cubed potatoes. Take a look and see if this recipe fits you best: https://www.willcookforsmiles.com/loaded-cheesy-potato-casserole/
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!
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.
It sounds like you made some creative and delicious adjustments to the recipe!
