  5. Spread about 1/2 to 1 cup of the marinara-spinach mixture over the bottom of the baking dish, just enough to coat the bottom.

  11. Grease a sheet of foil large enough to fit over the lasagna. Cover the lasagna tightly with the foil, greased side down. If your baking pan is very full, place a foil-lined baking sheet on a lower rack to catch spills.

Tip

  • When draining spinach, make sure to squeeze to eliminate as much liquid as possible.
