Potato, Sausage, and Spinach Breakfast Casserole

My family loves a big Sunday breakfast – and I love yoga.  I used to love a big Sunday breakfast as well – that was until I found this class.  It is not so much the class, as much as it is the instructor.  She just has a nice way of making you work very hard – and I always leave there much more relaxed than I arrived.  Every once in a while though (and it really doesn’t happen very often), I get caught up doing things, and I miss my Sunday morning escape.  When that happens, I usually can’t help it but make a big breakfast.

Recently I have been looking for recipes without using a pastry crust.  Don’t get me wrong, I love a good pastry crust, but it really adds a lot of time to whatever you are doing – and it is also just a little less healthy.  When I saw this recipe in Bon Appetit, I was fascinated with the potato crust.  The problem with a potato crust is that you have to get the bottom nice and crisp – if it isn’t, it ends up being a soft soggy mess.  So, I decided to give it a whirl, and see if I could make sure the crust was crisp enough for my taste.  I ended up using the packaged potatoes purely to save time – and they turned out great.  The crust was fantastic – and the kids loved it – even with the spinach.  You can see by my picture that my eggs didn’t mix as well as they should have, but it tasted wonderful.  So this Sunday, make the family a big breakfast – and then take yourself to yoga afterwards as a treat.  Your family will be so happy, they won’t even miss you while you are gone!
