How to Serve Low Carb Cauliflower Pizza Casserole
You can serve this casserole right out of the oven. It’s great on its own but pairs well with a green salad or some garlic bread. If you have any leftover toppings, set them out for guests to customize their portions.

To store leftovers, let the casserole cool completely. Then, cover it tightly with plastic wrap or foil and place it in the refrigerator. It will stay fresh for about 3-4 days. You can also freeze leftovers for up to three months. Just thaw in the refrigerator before reheating.
