    500 ml (2 cups) low fat milk (2%), 500 ml (2 cups) vegetable broth
  • Melt the margarine in a large pot over medium heat. Add the flour and stir continuously with a whisk until a smooth, well-blended roux forms.

  • Bring the mixture to a boil, stirring constantly, until a thick and creamy Béchamel sauce develops. Remove the pot from the heat and stir in the grated Graviera cheese until completely melted. Set aside and allow the sauce to cool down.

Preparing the Meat Sauce:

  • Heat 1 tablespoon of olive oil in a frying pan over medium heat. Add the chopped onion and minced garlic and sauté for about 5 minutes until soft and translucent.

  • Add the minced beef to the pot. Cook until the meat is browned, using a wooden spoon to break up any large chunks. Add the grated carrot and cook for another 2 minutes.

  • Stir in the tomato paste and roast it for a minute or two until it lightly sticks to the bottom of the pot. This enhances the depth of flavor.
    1 Tbsp tomato paste
  • Deglaze the pot with the dry red wine, scraping up the browned bits from the bottom. Season with thyme (or oregano), nutmeg, cinnamon, salt, and pepper. Let it simmer on medium heat until the liquid has completely evaporated.
    1 tsp cinnamon, ¼ tsp nutmeg, 1 tsp salt, ¼ tsp pepper, ½ tsp dried oregano or thyme, 100 ml (3.4 fl oz) dry red wine
  • Add the canned diced tomatoes and a pinch of sugar. Stir well, cover the pot halfway with a lid, and let it simmer over medium heat for another 15 to 20 minutes until the liquid reduces and you are left with a thick, rich meat sauce.

Preparing the Vegetables:

  • Preheat your oven to 200°C (390°F).
  • In the meantime, use your mandoline slicer to cut the potatoes, zucchini, and aubergines lengthwise into slices about 0.5 cm (0.2 inches) thick.

  • Prepping aubergines (eggplants) for the mandoline is easy when you follow this method. First, trim off the stem at the top and the blossom end at the bottom. If your aubergines are too long to fit onto the mandoline, simply cut them in half crosswise first, then slice those pieces in half lengthwise.
    • Here is my secret trick for the best texture: The tough outer skin on the very first rounded slice often stays quite firm in the oven. To avoid this, use a sharp knife to thinly shave off the rounded skin layer before using the mandoline. This ensures that even your very first slice has exposed flesh on both sides instead of a thick, closed layer of skin, allowing it to soften beautifully and absorb all the rich flavors of the dish!
  • Line a baking sheet with parchment paper and arrange the aubergine and zucchini slices on it. Use a fork to score gentle grooves lengthwise on top of each slice. Lightly season with salt and brush everything with 2 tablespoons of olive oil. Cover the vegetables with a second sheet of parchment paper and bake at 200°C (390°F) for 15 to 20 minutes until they are soft but not dry.

  • Toss the potato slices with 1 tablespoon of olive oil. Place them in the air fryer and cook at 195°C (380°F) for 25 minutes. Give the air fryer basket a quick shake after about 13 minutes to ensure the potatoes brown evenly.

Assembling and Baking the Moussaka:

  • Grease a 25x30 cm (approx. 10x12 inch) baking pan or casserole dish with ½ tablespoon of olive oil (about 3 sprays from an oil mister, which is around 1 g). Sprinkle 1 tablespoon of breadcrumbs evenly over the bottom.
    ½ tsp olive oil, 1 Tbsp bread crumps

  • Arrange the air-fried potato slices in an even layer at the bottom of the dish and season lightly with salt. Place the zucchini slices directly on top of the potatoes.

  • Separate the egg yolk from the egg whites. Whisk the two egg whites until stiff peaks form. In a separate small bowl, beat the egg yolk well, then gently fold it into the beaten egg whites.

    • Pro Tip for the Béchamel: Beating the egg whites until stiff makes the final Béchamel layer incredibly light and fluffy! However, if you are short on time, this step is optional—you can also just lightly beat the whole eggs and stir them in.
  • Stir this egg mixture into the Béchamel sauce, ensuring the sauce is only lukewarm so the eggs do not scramble.
  • Mix about ½ cup of the Béchamel sauce into the prepared meat sauce, then spread the meat mixture evenly over the zucchini layer.

  • Arrange the aubergine slices on top of the meat sauce, then pour the remaining Béchamel over everything and smooth it out with a spatula. Bake in the preheated oven at 200°C (390°F) for 35 to 40 minutes, or until the top turns a beautiful golden-brown.

  • Allow the Moussaka to cool down and rest for 45 to 60 minutes before slicing. This crucial step lets the layers set perfectly so it holds its shape when served.
