Lentil and Vegetable Moussaka with Low-Fat Béchamel

This DASH-friendly moussaka swaps traditional ground lamb and full-fat béchamel for a nourishing lentil and vegetable filling topped with a silky low-fat yogurt sauce. Layers of roasted eggplant, zucchini, and potato are built up with a cinnamon-spiced tomato-lentil ragù, delivering all the cozy, savory depth of the Greek classic while packing in plenty of fiber, potassium, and plant-based protein. Baking the vegetables instead of frying them in oil dramatically cuts saturated fat without sacrificing that melt-in-your-mouth texture. The béchamel here is made with low-fat milk, a touch of Greek yogurt, and just a whisper of reduced-fat cheese, keeping sodium and saturated fat in check while still achieving a creamy, golden-baked top. No added salt is needed thanks to the aromatic blend of garlic, oregano, cinnamon, and nutmeg that seasons every layer. The result is a comforting, make-ahead casserole that's perfect for a family dinner, and reheats beautifully for leftovers throughout the week — all while supporting healthy blood pressure and cardiovascular wellness.

Method

1. Preheat the oven to 425°F (220°C). Arrange eggplant, zucchini, and potato slices in a single layer on two baking sheets, brush lightly with 2 tablespoons of olive oil, and roast for 20-25 minutes, flipping halfway, until tender and lightly golden. Set aside and reduce oven temperature to 375°F (190°C). 25:00
2. While the vegetables roast, heat the remaining 1 tablespoon olive oil in a large saucepan over medium heat. Add the onion and sauté until softened, about 5 minutes.
3. Add the garlic and cook until fragrant, about 30 seconds.
4. Stir in the rinsed lentils, crushed tomatoes, vegetable broth, tomato paste, cinnamon, oregano, allspice, and black pepper. Bring to a boil, then reduce heat and simmer, stirring occasionally, until the lentils are tender and the sauce has thickened, about 25-30 minutes. 30:00
5. Stir the chopped parsley into the finished lentil ragù and remove from heat.
6. Make the béchamel: in a medium saucepan, whisk the flour into the milk until smooth, then place over medium heat and whisk constantly until the mixture thickens into a smooth sauce, about 5-7 minutes. 7:00
7. Remove the béchamel from heat and let cool slightly. Whisk in the Greek yogurt, beaten egg, nutmeg, and half of the Parmesan cheese until smooth and glossy.
8. Assemble the moussaka: arrange half the potato slices in the bottom of the baking dish, followed by half the eggplant and zucchini. Spread half the lentil ragù evenly over the vegetables.
9. Repeat with the remaining potato, eggplant, zucchini, and lentil ragù to form a second layer.
10. Pour the béchamel evenly over the top layer, spreading it to the edges with a spatula, then sprinkle with the remaining Parmesan cheese.
11. Bake at 375°F (190°C) for 30-35 minutes, until the top is golden brown and set. Let the moussaka rest for 10-15 minutes before slicing and serving. 35:00
