Hash Browns or Hashbrowns?
Spell check might disagree, but you can spell it either way! Hashbrowns, hash browns, or hashed browns (whew!) are a staple at our house. But no matter how you spell it, this hashbrown breakfast casserole is a must-bake!
If you happen to have shredded hash browns handy, you can use those in place of the patties. Just distribute evenly in a half-inch layer on the bottom of the dish.
Perfect for Special Occasions or Every Day
We love a good breakfast bake for a holiday breakfast, like Christmas morning. But this casserole is easy enough for every day. I love that you can feed a crowd with the (it serves 12) or save it for the rest of the week.
Spice it Up or Down
I’ve made this hash brown casserole with Pepper Jack cheese before and it’s so good. If you want to kick it up another notch, try adding a dash of hot sauce before eating. And if you have some picky eaters, it’s okay to leave out the red and green pepper. It loses a bit of the flavor for me, but does make it more kid-friendly.

Hi there! Delicious! But I’m curious if there is a way to make the hashbrowns yourself, or do you have to buy frozen packaged ones? Thanks!
Hi Tamara! You could certainly shred raw potatoes and bake them in a single layer on a greased sheet pan until they’re golden brown first and then use them instead of the frozen. I haven’t made the casserole this way myself, but I think it would turn out great. Hope this helps and that you get to enjoy it soon!
Can you assemble this the night before and cook in the morning?
Hi, Vanessa! Yes, you can! The hash brown casserole can be prepped in advance, covered and stored in the refrigerator overnight (or up to 24 hours) before baking according to the directions. That’s a great question. Thank you!
This recipe is absolutely delicious, I’ve made it 5 times already in the past 3 weeks… my 8 year old and 2 year old actually ate without the fussing. thank you for sharing.
Hi, Marueen! Oh my gosh — that really is a winner! Anything that they’ll happily eat is gold. I’m so happy y’all are enjoying it.
your recipes don’t have the amounts of ingredients like flour baking powder garlic salt are we supposed to guess?
Hi, Tina! Yes, of course they do! Scroll down to the recipe card (or use the easy “Jump to Recipe” button). You can print it or save it to your favorites. Hope this helps.
This recipe is delicious! I made it for our Christmas brunch and everyone loved it! I wish I would have made 2 pans because everyone kept going back for more. Super easy and not a lot of ingredients. I also used the frozen pre cut peppers and onion. It made things easier yet! Thank you for sharing the recipe. You saved the day
Hi, Mary! I’m so happy to hear that everyone loved it! I hope you had a wonderful Christmas.
I love this recipe. It has amazing taste. Will make this again. I used bacon 12 stripes instead of ham.
Can you sub shredded hash browns to make this?
Hi, Katy! Yes! You can use shredded in place of the patties. Just distribute evenly in a half-inch layer on the bottom of the dish. Hope this helps. Enjoy! ❤️
Curious, does the ham have to be cooked before putting in the oven or it cooks with it???
Hi, Rebecca! Great question! Most ham that is sold to consumers is already cured or smoked and doesn’t need to be cooked at all to eat. So no, you don’t have to do anything to it! Hope this helps. Enjoy! ❤️
very good
Hi, Diana! Thank you. I am so glad you enjoyed it!
