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.

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.
