How to: Big Batch Casserole-Cauliflower Mac and Cheese

I think that the word casserole can sometimes have a negative connotation. Maybe when you hear casserole you think of a super creamy and stinky tuna casserole? Or maybe you associate it with “leftover night” from your childhood where all the previous days leftovers were thrown together and baked in the oven, to try to create a new dish.

Well, forget everything you thought up until now because casseroles, my friends, are your weeknight dinner saviors! A big pan of vegetables, grains, and proteins is a healthy meal that can be made on the weekend and then portioned out for easy grab-and-go lunches or re-heated for quick weeknight dinners. One of my favourites is an updated version of the classic comfort dish, mac and cheese.

Cauliflower and spinach add lots of delicious veggie flavour to this dish, and a sauce made of Greek yogurt, milk, and cheese, makes it easier and lighter than the traditional butter and flour white sauce. Simply pair with a green salad and you’re good to go.
