Kitchen Equipment

  • Baking trays
  • Large skillet
  • Saucepan
  • Whisk
  • 9×13-inch baking dish
  • Sharp knife
  • Cutting board

Step 1: Roast the Vegetables

Preheat the oven to 200°C (400°F).

Arrange the eggplant, potato, and zucchini slices on baking trays.

Brush lightly with olive oil.

Season with salt and pepper.

Roast for 20–25 minutes, turning halfway through, until the vegetables are tender and lightly browned.

Set aside.

Step 2: Prepare the Vegetable Filling

Heat olive oil in a large skillet over medium heat.

Cook the onion for about 5 minutes until softened.

Add the garlic and cook for 1 minute.

Stir in the carrots, bell pepper, and mushrooms.

Cook for 8–10 minutes until the vegetables soften and excess moisture evaporates.

Add:

  • Tomato paste
  • Crushed tomatoes
  • Oregano
  • Paprika
  • Cinnamon
  • Cumin
  • Thyme

Season with salt and pepper.

Simmer for 20–25 minutes, stirring occasionally, until the sauce thickens.

Remove from the heat and stir in the chopped parsley.

Step 3: Make the Béchamel Sauce

Melt the butter in a saucepan over medium heat.

Whisk in the flour and cook for 2 minutes to create a smooth roux.

Gradually whisk in the warm milk until smooth.

Continue whisking until the sauce thickens.

Remove from the heat.

Whisk the egg yolks separately.

Slowly temper the yolks by adding a little warm béchamel while whisking.

Return the egg mixture to the saucepan.

Stir in:

  • Parmesan cheese
  • Nutmeg
  • Salt
  • White pepper

Mix until smooth and creamy.

Step 4: Assemble the Moussaka

Lightly grease a baking dish.

Layer the ingredients as follows:

  1. Half of the roasted potatoes
  2. Half of the eggplant
  3. Half of the zucchini
  4. Half of the vegetable filling

Repeat the layers with the remaining vegetables and filling.

Pour the béchamel sauce evenly over the top.

Spread gently with a spatula.

Sprinkle with grated Parmesan.

Step 5: Bake

Bake at 180°C (350°F) for 45–50 minutes, or until the top is golden brown and bubbling.

Allow the moussaka to rest for 20–30 minutes before slicing.

This helps the layers hold together and makes serving easier.
