Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Slice 2 large eggplants into 1/4-inch rounds. Arrange in a single layer on baking sheets, brush with 2 tbsp olive oil, and roast for 20 minutes until golden and tender, flipping halfway.
  2. Step 2: In a saucepan, combine 1/2 cup dried brown lentils with 1 cup vegetable broth. Simmer uncovered for 25 minutes until lentils are tender but not mushy.
  3. Step 3: Heat 1 tbsp olive oil in a skillet over medium heat. Add 1/2 cup diced onion and cook for 5 minutes until soft and translucent. Stir in 400g crushed tomatoes, 1 tsp dried oregano, 1/2 tsp cinnamon, and salt to taste. Simmer for 15 minutes until thickened.
  4. Step 4: Drain lentils, reserving 1/4 cup cooking liquid. Stir lentils into tomato sauce until well combined and thickened (add reserved liquid if needed).
  5. Step 5: Spread 1/3 of the lentil-tomato mixture in the bottom of a 9x13-inch baking dish. Layer with half the roasted eggplant slices, then spread remaining sauce on top.
  6. Step 6: Pour 1 cup béchamel sauce evenly over the top layer, then arrange remaining eggplant slices on top. Sprinkle with 1/4 cup kalamata olives.
  7. Step 7: Bake uncovered for 30 minutes until golden and bubbling around the edges. Let rest for 15 minutes before slicing to set the layers.
