What’s your favorite breakfast-for-dinner meal? Cheesy Hash Brown Casserole is a great meal for breakfast or dinner, combining two of my favorite ingredients…. potatoes and cheddar cheese!
Jump to RecipeCheesy Hash Brown Casserole comes straight from the 100 Days of Real Food book. It is a mixture of two of my favorite things…. potatoes and cheddar cheese!
This is super-simple to make, especially if you use frozen hashbrowns. And trust me, buy them frozen. I tried with homemade hash browns one time and it just didn’t work very well. I couldn’t get all of the moisture out of the potatoes and it was a runny mess.
Cheesy Hash Brown Casserole is a great option if you need a recipe for a pot-luck style brunch. I made it for my Mothers of Preschoolers meeting on month and everyone was asking me for the recipe. It was a great balance to the yogurt parfaits that we had with it.
I have this listed under breakfast
Step by Step
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 mixture to the greased baking dish and smooth it out as much as possible.
Bake the 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.

Hash browns are seriously delish! Great recipe!
Thanks! I love almost everything to do with potatoes, so this is a favorite.
Oh my! I have a feeling if I could still eat Dairy – would eat this wholeeeeee casserole in negative 10 seconds! LOL!
I have to limit myself because I would too if I really wanted to!
Ooohhh lovely!!! I love Casserole dishes and this dish sound super simple and super cheesy! I’d love to try this on the coming weekend.
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!
I love having good casserole recipes for brunch. Especially when it’s a potluck style and you get to try so many delicious foods!
This looks perfect for brunch! So bright and comforting! I have guests coming over next week and I was wondering what to make, this will definitely make my life easier that day! Thank you for always providing so much food inspo!!
Oh this is perfect for when you are cooking for a crowd because it makes a lot! I hope you and your friends enjoy!
That looks magnificent. & super easy. Yummm!

Cheesy Hash Brown looks easy to made nice one! I will copy this recipe to make my version I love it, 🙂
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.
