Step 1

Cut up the cauliflower into small pieces.  You can do this in a food processor or by hand.  Costco also sells a package that's already pre-cut and ready to go.

Step 2

Place the cauliflower in a deep casserole dish and sprinkle with olive oil and all the seasonings.

Step 3

Bake the cauliflower at 400 degrees for about 20 minutes or until it's tender.  The bigger the pieces the longer it will take to cook.

Step 4

Add one whipped egg to 1 cup of Rao's Marinara sauce.  This will create an extra thick sauce to help the casserole stick together when it bakes.

Step 5

Pour the prepared sauce over the cooked cauliflower while it's still warm.

Step 6

Add the cheese and additional toppings for your pizza casserole.

Step 7

Bake for another 10 minutes or so until all the cheese has melted and browned slightly.
