Notes

  • *For best results, use a mandolin slicer to cut the fennel and onions
  • If making ahead, assemble completely, but do not bake. Cover and store in the refrigerator up to 3 days ahead. Bake at 375 degrees F for about 30 minutes until its bubbling around the sides. If the top starts to get too brown, tent it with foil.
