What a week — it felt like a blur. I caught a miserable cold and it took everything I had just to keep everyone fed, dressed and out the door. Isn’t it amazing how something small can knock you off your feet? If I’d known it was coming, I would have made another breakfast casserole ahead of time so I’d have ready-to-serve slices in the fridge. Finally I’m on the mend and able to sit down and share this recipe.
I’ve made this casserole a few times and the second attempt nailed the cheese-to-seasoning balance. It’s simple to prepare and cooks in about three hours in a slow cooker.
This really is a powerhouse breakfast — quinoa, eggs and spinach combine into a filling dish that will keep you satisfied well past mid-morning.

You add the quinoa uncooked — it sinks to the bottom as it cooks and forms a pleasant base. The casserole is done when the eggs are set and the edges are lightly browned.
This recipe is flexible: swap in kale, add onions or peppers, or use other cheeses — make it with whatever you have on hand. It’s a keeper for us.
