Ingredients

  • 2 large eggplants, sliced into 1/2-inch rounds
  • 2 medium zucchinis, sliced into 1/2-inch rounds
  • 1 cup dried brown lentils, rinsed and drained
  • 1 large onion, finely chopped
  • 3 cloves garlic, minced
  • 1 can (14 oz) crushed tomatoes
  • 1/4 cup tomato paste
  • 1 teaspoon ground cinnamon
  • 1 teaspoon dried oregano
  • 1/2 teaspoon ground allspice
  • 1/4 cup olive oil, divided
  • 2 cups milk (use plant-based milk for vegan option)
  • 4 tablespoons all-purpose flour
  • 4 tablespoons butter or vegan margarine
  • 1 cup grated Parmesan cheese (or vegan alternative)
  • Salt and pepper, to taste
  • Fresh parsley, chopped (for garnish)

Equipment

  • Baking sheet
  • Large skillet or saucepan
  • Medium saucepan (for béchamel sauce)
  • 9×13 inch baking dish
  • Wooden spoon
  • Mixing bowls
  • Whisk
  • Knife and cutting board

Instructions

  1. Prepare the vegetables: Preheat your oven to 400°F (200°C). Arrange the eggplant and zucchini slices on a baking sheet, brush both sides with olive oil, and season with salt and pepper. Roast for about 20 minutes, flipping halfway, until tender and lightly browned.
  2. Cook the lentils: In a medium saucepan, add the rinsed lentils and 3 cups of water. Bring to a boil, then reduce to a simmer and cook for 20-25 minutes until lentils are tender but not mushy. Drain any excess water and set aside.
  3. Make the lentil sauce: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Add the garlic and cook for another minute.
  4. Add the cooked lentils, crushed tomatoes, tomato paste, cinnamon, oregano, allspice, salt, and pepper. Stir well, reduce heat, and let simmer for 15 minutes, stirring occasionally. Adjust seasoning as needed.
  5. Prepare the béchamel sauce: In a medium saucepan, melt butter over medium heat. Whisk in the flour and cook for 1-2 minutes to form a roux, stirring constantly.
  6. Gradually whisk in the milk, continuing to stir until the sauce thickens and is smooth. Remove from heat and stir in 3/4 cup of grated Parmesan cheese. Season with salt and pepper. Set aside.
  7. Assemble the moussaka: In your baking dish, layer half of the roasted eggplant and zucchini slices. Spread the lentil tomato sauce evenly over the vegetables.
  8. Add the remaining roasted vegetables on top of the lentil sauce.
  9. Pour the béchamel sauce evenly over the top layer, smoothing it out with a spatula. Sprinkle the remaining Parmesan cheese on top.
  10. Bake: Place the baking dish in the oven and bake at 350°F (175°C) for 40-45 minutes, or until the top is golden brown and bubbling.
  11. Allow the moussaka to cool for 15 minutes before serving. Garnish with freshly chopped parsley.

Tips & Variations

For extra flavor, you can sprinkle some nutmeg into the béchamel sauce.

If you prefer a vegan version, substitute the butter with vegan margarine, the milk with almond or soy milk, and use vegan Parmesan cheese.

Try adding sliced potatoes as an additional layer for more heartiness.

Another tip is to salt the eggplant slices before roasting to remove any bitterness and excess moisture. Let them sit for 20 minutes, then rinse and pat dry.
