It’s the ultimate set-it-and-forget-it meal that proves you don’t have to sacrifice flavor to eat well.
Ingredients
• MOUSSAKA
• 2 medium eggplants, 680 g / 1.5 lb
• 1 medium rutabaga, 400 g / 14.1 oz, peeled
• 1 1/2 teaspoons fine sea salt, or to taste
• 2 tablespoons ghee or other healthy cooking fat, 30 g / 1.1 oz
• 1 small yellow onion, 70 g / 2.5 oz, chopped
• 2 cloves garlic, minced
• 2.2 pounds ground lamb, 1 kg
• 3 tablespoons freshly chopped oregano, 12 g / 0.4 oz, or 1 tablespoon dried
• 3 tablespoons freshly chopped mint, 12 g / 0.4 oz, or 1 tablespoon dried
• 1 teaspoon ground cinnamon
• 1/2 teaspoon ground cloves
• 1 bay leaf, crumbled
• 1/4 teaspoon ground black pepper
• 2 tablespoons unsweetened tomato paste, 30 g / 1.1 oz
• 1 cup dry red wine, 240 ml
• BÉCHAMEL SAUCE
• 1 1/2 cups heavy whipping cream, 360 ml
• 4 egg yolks
• 1/4 teaspoon ground nutmeg
• 1 bay leaf, crumbled
• 1 1/2 cups grated Parmesan cheese, 135 g / 4.8 oz, divided
• Salt and pepper, to taste
Instructions
1. Grease your slow cooker with a small amount of ghee and set it to low. Cut the eggplant and rutabaga into 1/4-inch (1/2-cm) slices. Sprinkle the slices with salt and set aside for 20 minutes to draw out moisture, then pat the eggplant dry with a paper towel.
2. While the vegetables rest, heat the remaining ghee in a large saucepan or Dutch oven over medium-high heat. Add the onion and cook for 5-8 minutes until lightly browned. Stir in the garlic and cook for one more minute until fragrant.
3. Add the ground lamb to the saucepan, breaking it up with a spoon. Cook over medium heat for about 5 minutes until browned. Drain any excess fat.
4. Stir in the oregano, mint, cinnamon, cloves, crumbled bay leaf, black pepper, tomato paste, and red wine. Bring to a simmer and cook for 5-8 minutes, allowing the sauce to reduce by about half. Season with salt and pepper to taste and remove from heat.
5. Assemble the moussaka in the slow cooker. Start with a layer of rutabaga slices, followed by a third of the eggplant slices, and then half of the meat mixture. Repeat with another layer of rutabaga and eggplant, the remaining meat, and top with the final layer of eggplant and rutabaga.
6. Cover and cook on low for 6 hours.
7. After 6 hours, prepare the béchamel sauce. In a small saucepan, whisk together the heavy cream, egg yolks, nutmeg, and crumbled bay leaf. Cook over medium-low heat, stirring constantly, until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 1 cup of the Parmesan cheese until smooth.
8. Pour the béchamel sauce evenly over the moussaka in the slow cooker. Sprinkle the remaining 1/2 cup of Parmesan cheese on top. Cover and continue to cook on low for the final 2 hours.
9. For a golden, crispy top, carefully transfer the moussaka to an oven-safe dish and broil for 3-5 minutes, or place the slow cooker’s ceramic insert (if oven-safe) into a preheated 400°F (200°C) oven for 5-8 minutes. Serve immediately.

Pro Tips
• Don’t skip salting the eggplant. This crucial step draws out excess moisture and bitterness, preventing a watery moussaka and ensuring a silky, tender texture.
• For the best flavor, make the moussaka a day ahead. The flavors meld and deepen overnight. Let it cool completely, then refrigerate. Reheat gently in the oven until warmed through.
• If you don’t have ground lamb, ground beef is an excellent substitute. For a richer flavor, use a combination of half lamb and half beef.
• The final browning step in the oven is optional but highly recommended. It gives the cheesy béchamel topping a beautiful golden-brown crust and irresistible texture that you can’t achieve in the slow cooker alone.
