I made this for my boyfriend for his birthday cake because he wanted to eat healthy. I used green peppers and tomatoes instead of the suggested veggies and I also made chorizo to top it off. It turned out amazing!! We just made another batch because we want to start eating it on a daily basis to save time in the mornings! This time we put cut turkey bacon in the mix and it seems done enough. Thank you so much for this amazing recipe! 🙂

I added mushrooms to the other veggies plus garlic powder and red pepper flakes.
My family loved this healthy breakfast
casserole. It’s a keeper!

I can’t have milk so for the yogurt I’m wondering if it would taste ok if I used yogurt made with coconut milk or almond milk? Appreciate your opinion in time thank you

2 stars
The spinach in this recipe really took over and masked the flavor that should have come out with the other vegetables. I would omit it all together or use half the amount.

5 stars
I have made this probably 40 different times, 40 different ways, and it comes out amazing every time!!
(Variations were which vegetables I chose to include.)

why do the hash browns have to be frozen? I’m making it for someone who is GF and the hash browns we use are not frozen. Will it be a problem?

Hi Lisa, good question. The frozen hash browns are fairly dry, so fresh hash browns may release more moisture, which could create a watery texture to your casserole. You might be able to counteract that by salting and squeezing out your fresh hash browns beforehand.

Wondering why the instructions are to mix it after its in the casserole dish since its shallow and stuff spills out?,… saving a big bowl to wash?

Making it now for the 1st time – store was out of shredded hash browns so will try with cubed and let you know how it goes!

I have already thawed hash browns in my frig that I am trying to use up. Do you have any modifications for using thawed hash browns?

5 stars
Great recipe! Made it this morning (Christmas). Family loved it, although they probably wouldn’t have even tasted it if they knew it contained healthy spinach. That’s our little secret!

5 stars
Do you think this could be frozen? And would it be better to bake first then freeze, or freeze unbaked?

Thanks!
