Looks delicious! Wondering if this would be able to be divided and frozen in individual portions after cooking. Only two of us and a toddler and I like to have some quick breakfasts prepped to go.
I avoid white potatoes…including hash browns…would already cooked brown rice be a decent substitute? Diabetics should not eat white carbohydrates.
You could substitute with brown rice.
Can this be made in a insta pot
Dennis, unfortunately, I haven’t tried this in an insta pot.

Hello Hans! The eggs are not missing from the ingredients list. There are 6 eggs required for this recipe – they are listed among the other ingredients.
Yep…they are right there! And I will definitely be trying this recipe!
Melanie, enjoy the recipe! Hope you like it! 🙂
De-lish-ous!!! I used fresh breakfast sausage and about 2 1/2 cups of hash browns. I’m set for breakfasts for the week!!!!i will definitely make this again and play around with add-ins. Thank you so much!!!
You are very welcome! I am glad you found this recipe, tried it and liked it!
Can I assemble, refrigerate overnight and cook the next morning?
Yes, you can. Make sure to keep it covered air-tight in the refrigerator.
Is there a vegan substitute for the egg mixture?
And the cheese, heavy cream, and sausage? LOL
