Cheesy potatoes get added flavor when mixed with a few simple ingredients for a cheesy hash brown casserole breakfast sure to please any crowd.
Cheesy Hash Brown Casserole comes from the 100 Days of Real Food book. It is a mixture of two of my favorite things…. potatoes and cheddar cheese! It’s a copycat recipe for Cracker Barrel Hashbrown Casserole.
This is super simple to make, especially if you use frozen hashbrowns. And trust me, buy them frozen. Making hash browns from scratch might seem like a great idea, but let me tell you, it can be quite challenging. The key is to get the texture and moisture just right. Store-bought frozen hash browns are a convenient alternative that guarantees consistent results. By using frozen hash browns, you can save time and effort while still achieving deliciously crispy results. So, next time you’re in the mood for some homemade hash browns, remember to opt for the frozen variety – your taste buds will thank you!
Cheesy Hash Brown Casserole is a wonderful choice if you’re in need of a recipe for a pot-luck-style brunch. I prepared it for my Mothers of Preschoolers gathering last month and everyone was eagerly requesting the recipe. It served as a perfect complement to the delightful yogurt parfaits that we enjoyed alongside it. The combination of flavors and textures was absolutely delightful, making this dish a definite crowd-pleaser.
I have this listed under breakfast since most people associate hash browns as a breakfast food. I find that hash browns are the perfect way to start the day – their crispy exterior and tender interior make for a delightful morning treat. When the golden brown potatoes hit the plate, the aroma fills the air, instantly awakening your senses. Whether paired with eggs, bacon, or a stack of fluffy pancakes, hash browns add that extra touch of satisfaction to the breakfast table.
However, don’t underestimate the versatility of this beloved dish! Hash browns can also shine as part of a savory dinner. Imagine a chicken fried steak, smothered in rich gravy, accompanied by a side of crispy hash browns. The combination of flavors and textures is simply irresistible. This cheesy hashbrown casserole recipe is also a perfect side dish for so many meals. It would even be great with your holiday meals. So, regardless of the time of day, why not indulge in the deliciousness of hash browns?
Add-Ins and Garnish Ideas
The basic recipe is delicious as it’s made. But there are always ways you can add a few things into the casserole or on top to bring it to another level. Try any combination of these:
- Use cream of chicken soup, cream of mushroom soup, or cream of celery soup instead of milk for a creamier casserole
- Top it with a dollop of sour cream
- Add some crunch to the top with crushed corn flakes, panko bread crumbs, or crispy fried onions
- Mix in some meat by adding browned ground beef or ground turkey
- Use different cheeses to change the flavor
- Try substituting one cup of milk for one cup chicken broth

Cheesy Hash Brown Casserole Step by Step
Ingredients
- 6 tbsp butter
- 1/3 cup onion (diced)
- 1 clove garlic (minced)
- 4 tbsp all-purpose flour
- 1 1/2 cups milk
- 1/2 tsp salt
- 1 tsp pepper
- 2 cups mild cheddar cheese (freshly grated)
- 1 pound hash browns (frozen)
Preparation
Preheat the oven to 350F and grease a square baking dish. In a large skillet, melt the butter over medium heat then cook the diced onion for about 2-3 minutes, just until it softens. Add the minced garlic and cook for another minute.

Turn the heat down to medium-low and slowly whisk in the flour while stirring continuously. Whisk in the milk, salt, and pepper and stir until it thickens in the flour, about 2-3 minutes.

Remove the pan from the heat and add the shredded cheddar cheese. Stir continuously until the cheese has all melted.

Fold the hash browns into the cheese mixture. If your pan is big enough, you can do it in the pan. I prefer to mix it all in a large mixing bowl to make sure I have the space needed.

Transfer the cheesy hash browns mixture to the greased casserole dish and smooth it out as much as possible.

Bake the cheesy casserole for about 30-35 minutes, uncovered. The cheese should start to bubble but probably won’t be brown. If you want to brown the cheese, you can turn the broiler on for a few minutes.

Cheesy Hash Brown Casserole Leftovers
Storage: Once the casserole comes to room temperature, either cover with aluminum foil or plastic wrap or move the casserole to an airtight container. Refrigerate for 2-3 days.
Reheating: The best way to reheat the casserole is in the oven or in a saucepan over medium heat until warmed through.
Freezing: If you want to freeze this casserole, make sure it’s in a freezer-safe container with no extra air. Freeze for up to one month. Thaw in the refrigerator before reheating.

Hash browns are seriously delish! Great recipe!
Thanks! I love almost everything to do with potatoes, so this is a favorite.

It’s so cheesy, which is why I love it so much. It’s a great weekend breakfast (or breakfast-for-dinner) option.
A great recipe to be served on a cool fall day like today – yummy!
I agree, we love warm casseroles as the weather cools off a bit.
girl you are KILLING me with this recipe! cheddar and potatoes- same for me! I love potatoes too much but this looks divine! I made one once that I lost the recipe of that was cream of mushroom based and sour cream infused- so good! But i also used cubed instead because i grabbed it by mistake!
I don’t think I’ve had a potato casserole with cream of mushroom and sour cream, but that also sounds delicious!
Ooh, this sounds so yummy! I love hash browns and this sounds pretty straightforward to make… even for someone who isn’t a good cook like me lol!
Yes, it’s a very easy casserole to put together, and makes a lot for either breakfast or breakfast-for-dinner!
This sounds and looks delicious, Stephanie! My mom has several variations on this theme that are staples for her for brunches, so I will have to try this one sometime and add it to the mix!

It’s a delicious recipe, and would be easy to change a few things and make it your own.
OMG I love anything and everything with cheese. The casserole looks awesome and yummy
Me, too. The more cheese, the better for me!
I make one very similar to this but I don’t melt the cheese first, and it calls for sour cream. It is one delicious casserole, that’s for sure!
I bet sour cream would be a delicious add-on to this casserole. I like melting the cheese first because it distributes it through the entire casserole.
You had me at “cheesy.” Lol. This looks so delicious! Perfect for a weekend breakfast. Can’t wait to eat the carby goodness!
Yep, “cheesy” gets me every time, too!
We have a recipe that is similar to this that’s been in my family for years and it is ALWAYS A huge hit at potlucks and events! I love that you cook up your onions first, I am going to start doing that with mine <3
It never hurts to try something new with an old recipe. That’s how I’ve come up with some new, delicious recipes before.
Yum! This looks so amazing. My kids will absolutely love it…can’t wait to make it!!
My boys devour this most of the time when I make it. I hope yours like it just as much!
Such an interesting recipe! It looks amazing 😍 I haven’t tried this dish yet, so will have to make it someday soon ☺
I’ve made it a few times, including for a potluck brunch, and it’s always a hit.
This looks amazing! I love how easy it looks to make. I am going to make this soon.
It’s an easy meal and a great one to start in the morning and have dinner ready when you get home!
I love cheese and hash brown! Hash brown is one of my favorites for breakfast. This cheesy hash brown casserole sounds like an amazing recipe. would love to try this!
I really wish I had more recipes with hash browns, because I agree, they are such a great food for breakfast.
Oh Andrew loves hashbrown casserole! Its one of his favs. Maybe ill make this for him!
I’m sure there are a few ways to make it, but this is my favorite since it’s so cheesy! I hope he likes my version, too.
I am always looking for good casserole dishes over the cold months. This one looks tasty and my family loves hashbrowns! Thanks for this recipe!
I’ve brought this one to a few gatherings and it’s always very well received by everyone!
Oooooo so yum!!!! This reminds me of one of my favorite side dishes from cracker barrle. So need to make this for the family sometime
It’s very similar to the one served at Cracker Barrell. Of course, I changed a few things, but if you like that one you’ll like this, too.
It has been a long time since I had hash browns (they don’t have it as morning staple in Japan). I would so make this just to experience the taste of hash browns.
Oh man, I don’t eat them very often, but I would be sad if it wasn’t an option, too! Hopefully this gives you a little taste of them 🙂
Oh my gosh this is the best of both worlds a casserole and cheese. Will be giving this a go at the weekend. What a fab dish xx
Yes! I love anything cheesy so it’s a great casserole. It makes a wonderful brunch on the weekends, enjoy!
I love potatoes. So this looks super yummy and sounds delicious.
It’s a great way to have potatoes for breakfast in something a bit different than usual!
Can you make the night before and refrigerate?
I personally haven’t tried that yet, but I think if you were to do all of the steps up to baking, then refrigerate and bake in the morning, it should work. If you bake it then save, it may cook too much to cook the entire casserole again in the morning.
