Easy Egg White Casserole

Do you love a hearty, warm breakfast in the morning?

Do you agree that breakfast is the most important meal of the day?

Yes and yes, right? :)

Well then you’re going to love Fit for a Bride’s first recipe– a super easy egg white casserole! It’s simple to make, delicious, and will last the entire week if you eat just one serving a day… which, I’ll admit, is kinda tough cause it’s just that good!

Back about 3 years ago when I got serious about losing weight, this was one of the first healthy recipes I tried. I found it in Oxygen Magazine, which was my obsession at the time (still is!) and one night, I made this and a cashew butter stew from the latest issue. (It took me days to find cashew butter! I think that was the first time I stepped foot in Whole Foods!) I wasn’t a fan of the stew (such a bummer after working so hard to find the main ingredient!), but this recipe stuck! It was downright delicious and I loved it! And, ever since, every person I’ve ever given it to, has loved it too!


Did I mention my husband likes it? Yea and he’s Southern, and usually orders pancakes and double bacon for breakfast so the fact that he’ll eat this, in place of that, says a lot!


The absolute best part?

It’s easy! All you do is mix the ingredients, pop it in the oven for 45 minutes, and volia! Your healthy, hearty, hot breakfast for the week is ready to serve!

Wait no… the best part is how healthy this breakfast is- one serving is about 140 calories and it’s packed with protein! How awesome is that?

Alright, enough already! Time for you to try it yourself and see! Let me know what you think :)

    I prepared this dish last night so I could have it for breakfast this week. OMG I was shocked by how delicious it was! When I saw cottage cheese as an ingredient I was a little hesitant but I LOVED it. Thank you for sharing this.

    How many servings is an entire recipe?

    • admin

      Hey Candice! There’s six servings! It’s great for one week!

    Is 1 Tablespoon of Pepper correct? I brought this dish to work and everyone complained about it having too much pepper. Otherwise, it was yummy! I look forward to your response.

    • Sara

      Hi Melissa! I just double checked and your coworkers were right! It’s only supposed to be a teaspoon! I’m so sorry for the mix-up! I’ll fix this recipe now to reflect the change. I’m glad that it was well-received otherwise!

        I was also wondering when you are supposed to add the spinach? It is in the ingredients but not the instructions. Thanks again:)

        • Sara

          Hey again, Melissa! I add the spinach in once everything else (soft + dry ingredients) are combined. I think you can throw it in at anytime, though!

          • Melissa

            You should add this step into the instructions of the recipe:) That way other people that make this dish will not have the same question. Thanks for ALL your responses. I am definitely going to try it again soon!
