I love this dish, the recipe is from gourmetgirlcooks.
Moussaka (Topped w/ Grain-Free Bechamel)
INGREDIENTS:
2 medium eggplants, sliced lengthwise 1/4" thick (peeled, if desired)
Olive oil (as needed)
1 lb lean ground beef (or ground lamb)
1 large onion, chopped
3 cloves garlic, minced
1 (8-ounce) can tomato sauce
1 teaspoon dried oregano
1/2 – 1 teaspoon cinnamon, optional
1/2 teaspoon salt, or to taste
1/2 teaspoon fresh ground black pepper, or to taste
For the “Bechamel” Cheese Sauce
1 lb. ricotta
3 large eggs
1/2 cup grated Parmesan cheese (plus extra for sprinkling on top)
Nutmeg, dash/pinch
3 to 4 tablespoons heavy cream, optional
Directions:
Grease an 11 x 7” baking pan or similar sized casserole dish. Line a large cookie sheet with foil.
Brush each side of sliced eggplant with olive oil and sprinkle with salt and freshly ground pepper. Place the eggplant slices in a single layer on cookie sheet; broil until lightly brown; turn and broil the other side, brushing with additional oil, if needed until fork tender (alternatively, eggplant can be grilled). Arrange half the eggplant slices in the bottom of prepared baking dish; set aside.
While eggplant is cooking, in a large skillet, brown beef and onions; breaking beef into small pieces as it cooks. Cook until the beef is no longer pink and the onions are soft and translucent; add garlic and cook a few minutes more. Add tomato sauce, oregano, cinnamon, 1/2 teaspoon salt and black pepper (to taste); simmer uncovered about 10 minutes (there should not be much liquid left). Pour meat mixture over eggplant slices. Arrange the remaining eggplant slices over the beef mixture.
To make the bechamel/cheese sauce, in a medium bowl, whisk ricotta, eggs, 1/2 cup Parmesan cheese and dash of nutmeg until smooth and well blended; add salt and pepper to taste (careful not to over salt). Whisk in cream, to desired consistency. Pour the cheese sauce over the top of casserole and spread evenly. Sprinkle additional Parmesan cheese on top, if desired. Bake in a 350 degree F oven for 45 minutes. If desired, run casserole under the broiler for a few minutes to lightly brown. Let sit about 15-20 minutes to set before cutting into squares. Serves approximately 4 to 5.
***Note: Even though 8 ounces of tomato sauce is not much, the tomato sauce is only used to flavor the meat and keep it moist; it isn’t supposed to be like lasagna meat sauce. If you prefer not to add cinnamon to the meat mixture, you may omit it; however it is the unique flavor that “makes this dish” and gives it authentic flavor. Be sure to cook eggplant slices until completely tender (this is not a vegetable that is pleasant undercooked unless you like chewing on erasers).
