I've made many variations of this recipe over the last year or so, it's been a favorite. It's pretty flexible so you can swap up ingredients pretty simply. Don't have fresh onions? You can use frozen. Want to add a different veggie in sauce? Go for it. Just keep the measurements in a similar range and you'll be good to go. baked egg white casserole topped with melted cheese

This recipe is pretty much a crust-less quiche or even a frittata. I opted to call it a casserole because it's more creamy and not quite as firm as those traditionally are.

Hiya Diane! You absolutely can. According to my search, 3/4 cup of egg whites would be equivalent to 3 whole eggs. Hope that helps. ;)
