Notes

  • Storing leftovers: Keep leftovers in an airtight container in the fridge for up to 4 days. Reheat in the oven at 350°F until warmed through.
  • Freezing leftovers: Once cooled, place leftovers in a zippered bag and freeze for up to 2 months.
  • Properly prepare the broccoli and cauliflower before adding them to the casserole. Do not overcook or undercook them, as this can affect the texture of the casserole.
  • Steam instead of boil: If you prefer, you can steam the vegetables instead of boiling.
  • Use frozen veggies if needed: Frozen broccoli and cauliflower work great but cook them just until tender-crisp.
