Ingredients

Servings
  • 4 tablespoons butter divided, plus more for greasing the dish
  • 1 large fennel bulb thinly sliced (if very large, remove the core, or 2 smaller fennel bulbs
  • 2 onion peeled, halved and thinly sliced, medium-large, sweet
  • 1 teaspoon salt plus more to taste
  • black pepper freshly cracked, to taste
  • 1 teaspoon thyme sub ¼ teaspoon dried, fresh leaves
  • ¾ cup heavy cream
  • 1 ¼ cups Pecorino Romano cheese finely grated
  • 1 cup panko breadcrumbs

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.
