POTATO AND EGGPLANT MOUSSAKA RECIPES

Steps:

• Bake the eggplant: Preheat the oven to 475 degrees F. Brush the eggplant slices on both sides with the oil and lay on 2 small or 1 large foil-lined baking sheet. Season with salt and pepper. Cover with foil and bake until the eggplant is soft, about 25 minutes. Set aside covered. 
• Make the meat sauce. Heat the olive oil in a large skillet over medium-high heat. Add the onion and cook, stirring with a wooden spoon, until lightly browned, about 4 minutes. Add the garlic and cook, stirring frequently, until fragrant, about 1 minute. Add the beef, oregano, allspice, cloves, and cinnamon. Break the meat up into small pieces and season with the 1/2 teaspoon salt and pepper to taste. Cook, stirring occasionally, for about 2 minutes. Lower the heat to medium and cook, stirring, until just cooked but still slightly pink inside, about 1 minute more. Add the tomato and bay leaf and bring to a simmer. Cover, and cook until the sauce is thickened and fragrant, about 20 minutes. 
• Make the custard sauce. Melt the butter in a medium saucepan over medium heat. Whisk in the flour until smooth. Cook, stirring, for 1 minute. Remove the pan from the heat and add the milk, salt, and nutmeg. Return to the heat and while whisking constantly, bring to a boil. Simmer 2 minutes. Transfer the sauce to a bowl and stir to cool. When the sauce is cool, whisk in the egg and yolks. 
• Assemble the moussaka. Lower the oven to 350 degrees F. Brush a 9 x 13 x 2-inch casserole dish with the oil. Scatter the breadcrumbs over the bottom of the pan. Lay half of the eggplant in the pan, overlapping the slices if needed. Cover with half of the meat sauce and smooth with a rubber spatula. Repeat with the remaining eggplant and meat sauce. Pour the custard sauce over the layered mixture and smooth with a rubber spatula. Sprinkle with the Pecorino Romano and bake, uncovered, until lightly browned and the custard is set, about 1 hour. 
• Remove the moussaka from the oven and let rest for 10 minutes. Use a slotted spoon or spatula to serve.

Steps:

• Place a rack in middle of oven; preheat to 475°. Whisk half of the garlic, ½ cup oil, 1 Tbsp. mint, and 1 Tbsp. oregano in a small bowl. Brush both sides of eggplant rounds with herb oil, making sure to get all the herbs and garlic onto eggplant; season with salt and pepper. Transfer eggplant to a rimmed baking sheet (it’s okay to pile the rounds on top of each other) and roast until tender and browned, 35–45 minutes. Reduce oven temperature to 400°.
• Meanwhile, heat remaining 2 Tbsp. oil in a large wide pot over high. Cook lamb, breaking up with a spoon, until browned on all sides and cooked through and liquid from meat is evaporated (there will be a lot of rendered fat), 12–16 minutes. Strain fat through a fine-mesh sieve into a clean small bowl and transfer lamb to a medium bowl. Reserve 3 Tbsp. lamb fat; discard remaining fat.
• Heat 2 Tbsp. lamb fat in same pot over medium-high (reserve remaining 1 Tbsp. lamb fat for assembling the moussaka). Add onion, cinnamon, 2½ tsp. salt, and ½ tsp. pepper and cook, stirring occasionally, until onion is tender and translucent, 8–10 minutes. Add chiles and remaining garlic and cook, scraping up any browned bits from the bottom of the pot, until onion is golden brown, about 5 minutes. Add paprika and tomato paste and cook until brick red in color, about 1 minute. Add wine and cook, stirring occasionally, until slightly reduced and no longer smells of alcohol, about 3 minutes. Add tomatoes and break up with a wooden spoon into small pieces (the seeds will shoot out at you if you’re too aggressive, so start slowly—puncture the tomato, then get your smash and break on!). Add lamb and remaining 1 Tbsp. mint and 1 Tbsp. oregano and cook, stirring occasionally, until most of the liquid is evaporated and mixture looks like a thick meat sauce, 5–7 minutes. Pluck out and discard cinnamon stick.
• Heat butter in a medium saucepan over medium until foaming. Add flour and cook, whisking constantly, until combined, about 1 minute. Whisk in warm milk and bring sauce to a boil. Cook béchamel, whisking often, until very thick (it should have the consistency of pudding), about 5 minutes; stir in salt. Remove from heat and whisk in farmer cheese and half of the Pecorino. Let sit 10 minutes for cheese to melt, then add egg yolks and vigorously whisk until combined and béchamel is golden yellow.
• Brush a 13x9" baking pan with remaining 1 Tbsp. lamb fat. Layer half of eggplant in pan, covering the bottom entirely. Spread half of lamb mixture over eggplant in an even layer. Repeat with remaining eggplant and lamb to make another layer of each. Top with béchamel and smooth surface; sprinkle with remaining Pecorino.
• Bake moussaka until bubbling vigorously and béchamel is browned in spots, 30–45 minutes. Let cool 30 minutes before serving.
• Do Ahead: Moussaka can be baked 1 day ahead. Let cool, then cover and chill, or freeze up to 3 months. Thaw before reheating in a 250° oven until warmed through, about 1 hour.
