  • 1 large eggplant (sliced into rounds about 1/4 inch thick)
  • 16 ounces ricotta cheese (1 container)
  • 1/4 cup Parmesan cheese
  • 1 egg
  • 16 ounces sliced mushrooms
  • 24 ounces marinara sauce (1 jar)
  • 18 ounces prepared polenta (1 tube, sliced into rounds about 1/4 inch thick)
  • 16 ounces shredded mozzarella cheese


  • Preheat oven to 450 degrees F (230 degrees C).
  • Spray the eggplant rounds with a little olive oil spray, then place on a baking sheet and roast in the oven for about 20-25 minutes.
  • While the eggplant is roasting, in a medium bowl combine the ricotta cheese, Parmesan cheese, and egg.
  • Place the mushrooms in a microwave-safe dish and heat about 5 minutes on high, stirring halfway through, to soften them slightly.
  • Once the eggplant is done, turn the oven down to 350 degrees F (175 degrees C).
  • Spread a little of the marinara sauce on the bottom of a 9x13 casserole pan.
  • Place half of the polenta rounds on top of the sauce.
  • Spread half of the ricotta mixture on top of the polenta.
  • Place half of the eggplant rounds on top of the ricotta mixture.
  • Distribute half of the mushrooms on top of the eggplant.
  • Sprinkle half of the mozzarella cheese on top of the mushrooms.
  • Spread half of the marinara on top of the mozzarella.
  • Layer the rest of the ingredients: polenta, ricotta mixture, eggplant, mushrooms, sauce, mozzarella cheese.
  • Cover the dish with aluminum foil and bake for 30 minutes, then remove the foil and bake for about 15 additional minutes.
