Hash Brown Breakfast Casserole

Wednesdays are my favorite day of the week.  After the morning rush, it’s the day I get to refuel.

Once The Littles are off to school, it’s my day to relish.  And relish it, I do.  Every single minute of it.

I get to soak in Wednesday mornings with a group of remarkable, faith filled women.  We have the amazing privilege of doing life and learning together.

Whether it’s learning about ourselves as moms, wives, daughters, or friends…it’s so much fun tackling it all together.

There’s coffee, authentic friendship, laughter, tears, and always food…

All the Breakfast Favorites in one casserole

Whenever I make breakfast casseroles, I think of Wednesday mornings.  Somehow, most events are tied with food in my brain.  To be fair, breakfast casseroles frequently appear next to all the pastries and coffee.

I also can’t help but notice it because I’m a breakfast casserole freak.  Anything that’s got tons of savory goodness combined into one baked dish is begging to jump on my plate.

My whole family is fanatical about hearty breakfast casseroles.  When I don my Nice Mom hat, I make them breakfast for dinner.

Use Hash Brown Patties

This Hash Brown and Tomato Breakfast Casserole is easy peasy, 120% delicious, and pretty much will melt your favorite peoples’ hearts.

Or tummies.  We think they (and you) will adore this mouthwatering dish as much as we do.

Because this.  Hash brown patties.  We’re going down a good path already.

Baby Spinach and Ground Sausage

Add in fresh leaves of spinach.  Even if you have non-spinach fans, they’ll forgive you for this because the baby spinach softens all up and lets the other flavors shine.

Meaning you can’t really taste it.  Unless you want to.  In which case, feel free to add more spinach.  Not one of my Littles noticed the spinach this time, so I’m upping it next time ‘cuz Hubby and I love our greens.

Layer on the scrumptious breakfast sausage.  Browned, seasoned, oh-so-good.

Melty Cheese and tomatoes

Throw on the cheese.  Always the melty cheese.

Pour in the creamy egg mixture.  Somehow, I don’t know how, it all gets wonderfully soaked into the casserole.

Layer on the beautiful red tomatoes.  Followed by more cheese, if you like.  Who doesn’t like?

By the way, when one of my boys saw the tomatoes, he doubtfully questioned the edibleness of this dish.  Then he took a bite and scarfed his entire plate away in, oh, 30 seconds maybe.

Seconds and thirds got dished out to every kid.  Win.

Soft, tender potatoes enveloped in cheesy goodness.  Savory browned sausage.  Roasted tomatoes on top.  Easy, pretty, and totally satisfying.

Most importantly, it’s deeelish.  The bottoms and sides get nicely browned, which earns bonus points.

Breakfast, brunch, dinner… it’s served.  Enjoy!

    I made this recipe on christmas morning this year and it was so delicious! I’ve tried a few breakfast bakes before but not had much success. The ratios in this recipe are spot on. I used an entire bag of baby spinach but other than that I followed the recipe exactly. The hash browns had a nice potato flavor, the sausage gives the eggs great flavor and the tomato adds freshness. I highly recommend this recipe! Note: I didn’t prepare it in advance because I didn’t want the pan to be too cold and mess up the cooking times but it was very quick and easy to throw together.

      Amanda, so so happy you all loved this breakfast! Thanks so much for coming over to let us know. Happy continued cooking! 🙂

    • Alice

    This looks so good. Can I make it the night before and heat it up the next morning?

      • chewoutloud

      Alice, it’s best if you prepare it (but not bake) the night before and cook the morning of. However, if you’re short on time, then yes you can bake it the night before and reheat next morning. It will still taste yummy. Enjoy! 🙂

    • Nannette M Rudy
