Calories in Moussaka: A Classic Recipe and Serving Guide

Moussaka is a layered Greek casserole, commonly made with eggplant, spiced ground lamb or beef, tomato sauce, and a creamy béchamel topping. Its calories vary with portion size and how much oil, meat, and butter the recipe uses; this version balances those ingredients and makes eight servings.

Ingredients

2 large eggplants, about 2 lb (900 g) total, sliced lengthwise into ¼-inch (6 mm) planks
3 tablespoons (45 ml) olive oil, divided
1 teaspoon (6 g) fine salt, divided, plus more as needed
1 lb (450 g) ground lamb or lean ground beef
1 medium yellow onion, about 7 oz (200 g), finely chopped
2 garlic cloves, minced
1 can crushed tomatoes, 14.5 oz (410 g)
2 tablespoons (30 ml) tomato paste
½ cup (120 ml) dry red wine or beef broth
1 teaspoon (2 g) ground cinnamon
½ teaspoon (1 g) dried oregano
¼ teaspoon (0.5 g) black pepper
2 tablespoons (28 g) unsalted butter
¼ cup (32 g) all-purpose flour
2 cups (480 ml) whole milk, warmed
1 large egg, lightly beaten
½ cup (50 g) finely grated Parmesan cheese, divided
⅛ teaspoon ground nutmeg

Instructions

Heat the oven to 425°F (220°C). Line two baking sheets with parchment. Brush the eggplant slices on both sides with about 2 tablespoons (30 ml) of the olive oil and season with half the salt. Arrange in a single layer, working in batches if needed, and roast for 20–25 minutes, turning once, until softened and lightly browned. Set aside. Reduce the oven to 375°F (190°C).
While the eggplant roasts, make the meat sauce. Heat the remaining 1 tablespoon (15 ml) olive oil in a large skillet over medium heat. Add the onion and cook for 5 minutes, stirring, until softened. Add the garlic and cook for 30 seconds. Stir in the lamb or beef, breaking it up with a spoon, and cook until browned, about 7–9 minutes. For food safety, cook ground meat to the USDA FSIS safe minimum internal temperature of 160°F (71°C), checked with a food thermometer.
Stir in the tomato paste, cinnamon, oregano, pepper, remaining salt, crushed tomatoes, and wine or broth. Bring to a gentle simmer, then cook uncovered for 15 minutes, stirring now and then, until thick but still moist. Taste and adjust the seasoning. If the sauce looks watery, simmer a few minutes longer so the layers hold together.
Make the béchamel as the sauce finishes. Melt the butter in a saucepan over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly. Gradually whisk in the warm milk, then cook for 5–7 minutes, whisking often, until smooth and thick enough to coat a spoon. Remove from the heat. Whisk a spoonful of the hot sauce into the beaten egg, then slowly whisk that mixture back into the saucepan. Stir in the nutmeg and half the Parmesan. Tempering the egg first helps prevent it from scrambling.
Lightly oil a 9-by-13-inch (23-by-33 cm) baking dish. Arrange half the eggplant in an even layer, spread the meat sauce over it, then cover with the remaining eggplant. Pour the béchamel over the top and spread gently to the edges. Sprinkle with the remaining Parmesan.
Bake at 375°F (190°C) for 35–40 minutes, until bubbling at the edges and golden on top. If the center is not hot, continue baking until it reaches 160°F (71°C), the USDA FSIS safe minimum for an egg dish, checked with a food thermometer. Rest for 20 minutes before cutting; this helps the layers settle. The active preparation takes about 50 minutes, cooking about 1 hour 25 minutes, and the required rest 20 minutes.

Tips

Choose firm eggplants with glossy skin. Roast them until pliable and browned; undercooked slices can stay tough in the finished casserole.
Use lean ground beef for a milder, often lighter-tasting result, or lamb for its richer flavor. Ground turkey is another option, but it changes the traditional flavor and must also reach 165°F (74°C) because it is poultry.
For a less rich topping, use 2% milk, though the béchamel will be less creamy. Parmesan is a practical substitute for hard-to-find kefalotyri; it gives the topping a slightly different, more familiar savory flavor.
Let the baked dish rest before slicing, and avoid making the béchamel too thin. A loose sauce or cutting immediately can make the layers slide apart.

Serving Suggestions

Serve a square of moussaka with a crisp green salad dressed with lemon and olive oil, or alongside steamed green beans. A modest portion with vegetables makes a satisfying meal; the casserole is rich enough that bread is optional. For a useful calorie estimate, divide the full casserole into eight equal pieces rather than relying on an unspecified restaurant serving size.

Calories are not fixed because brands, meat fat percentage, eggplant size, and the amount of oil absorbed all differ. With the quantities above, a rough estimate is about 430–500 calories per serving, assuming eight portions and lean ground meat. This is an estimate, not a nutrition label; calculate with the specific ingredients and weights used if you need a closer figure.

Variations

For a meat-free version, replace the ground meat with 12 oz (340 g) chopped mushrooms and 1 cup (170 g) cooked brown or green lentils. Brown the mushrooms well before adding the tomatoes; the result will taste earthier and have a different texture. For a lighter-feeling plate, serve smaller portions with extra salad rather than cutting the béchamel or oil so far that the layers dry out.

Potato is included in some family and regional versions. To add it, roast 1 lb (450 g) of thinly sliced potatoes until nearly tender and use them as a base layer. The casserole will be more filling and its calorie count will change. You can also use a mix of eggplant and zucchini, but roast the zucchini first so it releases moisture rather than making the dish watery.

Storage and Reheating

Refrigerate leftovers within 2 hours of baking, covered in an airtight container or tightly wrapped in the baking dish. Keep for 3–4 days. Freeze portions in freezer-safe containers for up to 3 months for best quality; thaw overnight in the refrigerator. Reheat individual portions in a covered microwave-safe dish or in a 350°F (175°C) oven until the center reaches 165°F (74°C), the USDA FSIS temperature for reheated leftovers. Reheat only the portion you plan to eat.

Frequently Asked Questions

How many calories are in a serving of moussaka?
A serving of this recipe is estimated at roughly 430–500 calories when divided into eight portions. The exact total depends on the meat’s fat content, how much oil the eggplant absorbs, and the size of each slice.

Is moussaka high in calories?
It can be calorie-dense because it combines meat, oil, and a butter-and-milk béchamel. Portion size and sides affect the calories in a meal; a measured slice with a vegetable salad is an easy way to serve it thoughtfully.

Can I make moussaka ahead?
Yes. Assemble it, cover, and refrigerate for up to 24 hours before baking. Let the cold dish sit at room temperature only while the oven heats, then bake until bubbling and the center reaches 160°F (71°C). It may need extra time compared with a freshly assembled casserole.

Do I need to salt eggplant before cooking?
No. Modern eggplant is generally not as bitter as older varieties, and roasting it directly works well here. Salting and draining can remove some moisture, but it adds time and is not necessary for this recipe.

Can I make moussaka without wine?
Yes. Replace the red wine with the same amount of beef broth or water. Wine adds acidity and depth, but the tomato, cinnamon, and browned meat still make a flavorful sauce without it.

Why did my moussaka turn watery?
The eggplant or meat sauce may have held too much moisture. Roast the eggplant until tender and browned, and simmer the meat sauce until thick before layering. Resting the baked casserole for 20 minutes also gives the juices time to settle.
