Remove the pan from the heat.
  • Sprinkle half the cheeses over the bread cubes in the casserole dish then top with the spinach onion mixture and half the tomatoes. Layer the remaining bread cubes over the spinach, then top with the remaining tomatoes, Gruyere and Parmesan.

  • Cover the casserole dish with plastic wrap and refrigerate overnight.
