Variations

You can easily adapt this casserole to suit your taste. Add cooked chicken or ground beef for a heartier version. Swap cauliflower with broccoli for a different flavor profile. For a lighter option, use low-fat cheese and soup. Adding breadcrumbs on top before baking can give it a crispy texture.

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in the oven at 170°C (325°F) until warmed through, or microwave individual portions for a few minutes. If reheating in the oven, you can cover it with foil to prevent the cheese from over-browning.
