Elements in this hashbrown breakfast casserole
Again, the name is only half of the way you can serve it. We make this hashbrown breakfast casserole for friends who just had a baby as a vegetarian dinner. Because it’s easy to make in advance and doesn’t need to be reheated, it’s perfect for transporting to friends who need a meal. And, it’s a great savory option for a family brunch! Here’s what you’ll need:
- Frozen hashbrowns: Find a 1 pound bag in your local grocery. You can throw them in right from frozen!
- Eggs: 1 dozen makes it a super filling recipe for a crowd
- Sour cream adds just the right richness
- Milk
- Shredded cheddar cheese
- Green onions
- Red bell pepper
- Spices: Chili powder, garlic powder, cumin, salt
You don’t even need to saute the veggies! Just throw everything in a 9 x 13″ pan and bake it up. (Of course, whisk the eggs first.) It’s seriously simple. Jump down to the recipe for all the info!
Frozen hashbrowns are easy, or use potatoes
This hashbrown breakfast casserole uses the magic of frozen hashbrowns to make a quick casserole in no time. There’s actually nothing processed about frozen hash browns: they’re simply potatoes! However, some hash brown brands can include extra flours or fillers. Check the package ingredients to make sure!
If you’d like, you can also use potatoes! Use 1 pound of russet potatoes, which is the perfect type for hashbrowns. In the recipe below, we’ve included instructions on how to quick soak them so they’re the consistency of frozen hashbrowns, like in our Homemade Hash Brown recipe. See below for more!
How long does hashbrown breakfast casserole last
This breakfast casserole is super unfussy. To put it together, all you have to do is dump and stir: then bake for 50 to 55 minutes. The best part? Leftovers last for days. The pan makes enough for 8 servings, so we always make it for our family then refrigerate the leftovers.
- Leftovers are good for 5 days, refrigerated.
- To serve, you can eat cold, room temperature, or warmed in a 350 degree oven.
Make ahead info
Want to make this breakfast casserole ahead? You can assemble it, then cover with aluminum foil and refrigerate overnight. In the morning, bake as instructed in the recipe. You may need a few extra minutes in the oven. (We had a reader test this method and she said it worked great!)
It’s a vegetarian breakfast casserole, too!
Many breakfast casserole recipes have sausage. This one skips the meat, so it’s a vegetarian breakfast that works for various eaters! The flavor is so savory and delicious, you don’t need the meat. It’s also free of gluten, so it’s a nice gluten free breakfast option, too.

- 1 tablespoon garlic powder

Notes
*Or, use 2 medium russet potatoes (1 pound). Wash the potatoes, leaving the skins on. Use the large side of a box grater or a food processor large grating blade to grate the potatoes. Place the grated potatoes into a large bowl and fill it with cold water. Tip the bowl to drain off starchy water, then fill it again. Stir the potatoes to release starches soak them for 2 minutes. Drain the grated potatoes and squeeze out any excess water. Transfer them to a clean, dry towel. Wring the potatoes in the towel to remove as much liquid as possible.

Recipe says – a tablespoon each of chili powder, garlic powder and cumin. That sounds like huge amounts. I that correct or is it teaspoons not tablespoons?
That’s correct! It’s a lot but you need it for the flavors to come through.
Alex, does it freeze well?
This should freeze well! Place in a sealed container and freeze up to 3 months.
Delicious
potatoes are mushy. poor texture.
Could this be made the day before? Refrigerated, & served the next morning?
Hi! Yes — you can serve cold or reheat in the oven.
This was so good!! It will definitely be my go-to egg bake. I also made a gazillion substitutions and it was still 🔥🔥 (I only used 8 eggs, 1/2 c. Water instead of milk, only 1 Tbsp. of sour cream, used Simply Potatoes hash browns and used 3 bell peppers). I can see this being a great blueprint where you could easily mix up the veggies, cheese, and seasonings and always end up with something delicious.
I have a bag of refrigerated hashbrowns. I’m wondering if this would also work?
Yes, they will work the same.
This looks so good. I have a question. The recipe says 8 servings but I notice on the picture it is cut into 12 servings. Is the nutrition information for 8 servings? Thanks.
Hi! The nutrition is for 8 hearty portions — we just liked the way 12 looked in the picture :)
Yay!! Thank you!!
I am going to make this week , looks tasty & fast .
