• 2 large eggplants (about 2.5 lbs / 1.2 kg), sliced into 1/2-inch (1 cm) rounds
• 1 tablespoon coarse sea salt
• 2 tablespoons olive oil
• 1 teaspoon dried oregano

• 1 (28-ounce / 800g) can crushed tomatoes
• 2 tablespoons tomato paste
• 1 cup beef or chicken broth
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 2 teaspoons dried oregano
• 2 bay leaves
• 1 teaspoon salt, or to taste
• 1/2 teaspoon black pepper
• 1/4 cup chopped fresh parsley
• For the ‘Skinny’ Béchamel Sauce:
• 2 cups plain, non-fat Greek yogurt
• 2 large egg yolks
• 3 tablespoons cornstarch (or all-purpose flour)
• 1/4 cup skim milk
• 1/2 cup grated Parmesan or Kefalotyri cheese
• 1/4 teaspoon ground nutmeg
• Pinch of white pepper
• Pinch of salt

Instructions

1. Step 1: Prepare the Eggplant
2. Place the eggplant slices in a colander in a single layer (you may need to do this in batches). Sprinkle generously with the coarse sea salt and let them sit for 30 minutes. This process, called ‘sweating,’ draws out excess moisture and bitterness. You will see beads of water form on the surface. After 30 minutes, rinse the eggplant slices thoroughly under cold water to remove the salt and pat them completely dry with paper towels. This step is critical to prevent a watery moussaka.
3. Step 2: Bake the Eggplant
4. Preheat your oven to 400°F (200°C). Line two large baking sheets with parchment paper. In a large bowl, toss the dried eggplant slices with 2 tablespoons of olive oil, 1 teaspoon of oregano, and a few grinds of black pepper until evenly coated. Arrange the slices in a single layer on the prepared baking sheets. Bake for 20-25 minutes, flipping halfway through, until the eggplant is tender and lightly golden. Set aside.
5. Step 3: Make the Meat Sauce
6. While the eggplant bakes, heat 1 tablespoon of olive oil in a large skillet or Dutch oven over medium-high heat. Add the chopped onion and cook for 5-7 minutes, until softened and translucent. Add the minced garlic and cook for another minute until fragrant. Add the ground meat to the skillet, breaking it up with a spoon. Cook until browned all over, about 8-10 minutes. Drain off any excess fat.
7. Step 4: Simmer the Sauce
8. If using, pour in the red wine to deglaze the pan, scraping up any browned bits from the bottom. Let it simmer and reduce for 2-3 minutes. Stir in the tomato paste, followed by the crushed tomatoes, broth, cinnamon, nutmeg, oregano, bay leaves, salt, and pepper. Bring the mixture to a boil, then reduce the heat to low, cover, and let it simmer for at least 30 minutes (or up to an hour for deeper flavor), stirring occasionally. The sauce should be thick and rich. Once done, remove the bay leaves and stir in the fresh parsley.
9. Step 5: Create the ‘Skinny’ Béchamel
10. While the meat sauce simmers, prepare the béchamel. In a medium bowl, whisk together the cornstarch and skim milk until a smooth slurry forms, with no lumps. In a separate, larger bowl, whisk the Greek yogurt and egg yolks until smooth. Slowly stream the cornstarch slurry into the yogurt mixture, whisking constantly until fully combined. Stir in the grated Parmesan cheese, nutmeg, white pepper, and a pinch of salt. Set aside.
11. Step 6: Assemble the Moussaka
12. Reduce the oven temperature to 375°F (190°C). Spread a thin layer (about 1/2 cup) of the meat sauce on the bottom of your 9×13 inch baking dish. Arrange half of the baked eggplant slices over the sauce in a single, slightly overlapping layer. Top with half of the remaining meat sauce, spreading it evenly. Repeat with another layer of the remaining eggplant slices and the rest of the meat sauce.
13. Step 7: Top and Bake
14. Carefully pour the Greek yogurt béchamel over the top layer of meat sauce, using a spatula to spread it evenly to the edges. Bake, uncovered, for 40-45 minutes, or until the top is beautifully golden brown and the sauce is bubbling around the edges.
15. Step 8: Rest and Serve
16. This is a crucial step! Let the moussaka rest for at least 15-20 minutes before slicing and serving. This allows the layers to set, ensuring you get a clean, beautiful slice. Garnish with additional fresh parsley if desired.

Expert Cooking Tips

• Don’t skip sweating the eggplant. It’s the number one defense against a watery, bland moussaka.
• For the richest flavor, let the meat sauce simmer for as long as you can. The flavors will meld and deepen over time.
• When making the béchamel, ensure your cornstarch is fully dissolved in the milk before adding it to the yogurt to prevent lumps.
• Letting the moussaka rest after baking is non-negotiable. It needs time to set, otherwise the layers will collapse when you try to serve it.

Substitutions and Variations

For a vegetarian version, substitute the ground meat with 2 cups of cooked brown or green lentils and 1 lb of chopped mushrooms, sautéed with the onions. For gluten-free, ensure you use cornstarch (as written) or a gluten-free all-purpose flour blend in the béchamel. You can also use ground lamb for a more traditional flavor, but be sure to choose a lean cut. Zucchini slices, prepared the same way as the eggplant, can be used to replace up to half of the eggplant for a different flavor profile.

Common Mistakes to Avoid

The most common mistake is a watery final product, which is almost always caused by not salting and drying the eggplant properly. Another pitfall is a bland meat sauce; be generous with your spices (cinnamon and nutmeg are key!) and don’t skimp on the simmering time. Finally, rushing the resting period will result in a messy serving; patience is key to a perfectly layered slice.

Serving Suggestions

This skinny moussaka is a complete meal in itself, but it pairs beautifully with a crisp, simple side. Serve with a traditional Greek salad (horiatiki) dressed in lemon juice and olive oil, or some simple steamed green beans with a squeeze of lemon. A side of tzatziki can also provide a cool, refreshing contrast to the rich casserole.

Storage and Reheating Tips

Moussaka is an excellent make-ahead dish. Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. The flavors actually improve by the second day. To reheat, place individual slices in the microwave or cover the baking dish with foil and reheat in a 350°F (175°C) oven until warmed through. You can also freeze individual portions for up to 3 months. Thaw in the refrigerator overnight before reheating.

Frequently Asked Questions

Can I prepare the moussaka in advance?

Absolutely. You can assemble the entire casserole, cover it tightly with plastic wrap, and refrigerate it for up to 24 hours before baking. You may need to add 10-15 minutes to the baking time if it’s going into the oven straight from the fridge.

Why use Greek yogurt for the béchamel?

Traditional béchamel is made with butter, flour, and whole milk, which adds significant fat and calories. Using non-fat Greek yogurt provides the same creamy texture and a delightful tang, while dramatically cutting fat and adding a substantial protein boost.

My meat sauce seems too thin. What should I do?

If your sauce is too thin after simmering, simply remove the lid and continue to simmer on low heat, allowing the excess liquid to evaporate until it reaches your desired, thick consistency. Remember, it will thicken slightly as it cools.
