For the Casserole:

For the Topping:

  • ½ Cup Shredded Mozzarella Cheese
  • ¼ Cup Crumbled Blue Cheese


  • Preheat oven to 350.
  • In a large mixing bowl, mix together all the ingredients for the casserole.
  • Spread into a 9x13 baking dish.
  • Top with Shredded Mozzarella Cheese and Crumbled Blue Cheese.
  • Bake for 35-40 minutes, or until casserole is bubbly and cauliflower is cooked through - see note below. (I like to broil mine for the last several minutes.)


If you use the frozen cauliflower florets, you will need to bake it for at least 40 minutes - perhaps a touch longer. If using the cauliflower rice, you shouldn’t need to bake it quite as long.
I buy Great Value Frozen Spinach, and it comes loosely in a bag. I find this is easier to use for casseroles because you can grab a handful and throw it in. 
If you buy your frozen spinach in the small blocks, you will probably want to thaw it and squeeze the excess moisture out before using it.
