Instructions

  1. Step 1: Preheat oven to 425°F. Lay 2 large eggplants sliced into 1/4-inch rounds on baking sheets and brush both sides with 2 tbsp olive oil. Roast for 20 minutes, flipping halfway, until golden and tender.
  2. Step 2: While eggplant roasts, heat remaining 2 tbsp olive oil in a saucepan over medium heat. Add 4 minced garlic cloves and 1 finely chopped medium onion, sauté for 5 minutes until translucent and fragrant.
  3. Step 3: Stir in 14 oz canned crushed tomatoes, 1 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper. Simmer sauce over low heat for 15 minutes until thickened.
  4. Step 4: In a 9x13-inch baking dish, spread 1/3 of the tomato sauce on the bottom. Arrange half of the roasted eggplant slices in a single layer, spoon over 1/2 cup mozzarella and 1/4 cup Parmesan cheese, then sprinkle with half of the chopped 1/4 cup fresh basil.
  5. Step 5: Repeat the layering with remaining tomato sauce, eggplant slices, mozzarella, Parmesan, and basil. Finish with remaining cheese on top.
  6. Step 6: Bake uncovered at 375°F for 25 minutes until cheese is melted and bubbly with lightly browned edges. Let rest 10 minutes before serving to let flavors meld.
