Breakfast Casserole Tips

  • You can easily assemble the night before and refrigerate so flavors meld and mornings stay stress-free.
  • You can swap out veggies and meats, but make sure to stick to the measurements, so that the egg to veggie and hashbrown ratio is spot on and the casserole isn’t overly dry.
  • Let it rest – Cool for 5–10 minutes before serving so it sets and slices cleanly.
