Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish.
In a large skillet over medium heat, heat olive oil. Add eggplant slices and cook until lightly browned, about 5 minutes. Remove from heat and set aside.
In the same skillet, sauté onion and garlic until softened, about 5 minutes. Stir in the flour and cook for 1 minute.
Stir in the chicken broth, heavy cream, and Italian seasoning. Cook, stirring constantly, until the sauce is thickened, about 5 minutes.
Spread 1/2 of the eggplant slices in the prepared baking dish. Top with 1/2 of the sauce mixture, 1/4 cup Parmesan cheese, and 1/4 cup mozzarella cheese.
Repeat the layers with remaining eggplant slices, sauce mixture, and cheeses.
Bake for 25 minutes, or until the cheese is melted and bubbly.
Let cool for 10 minutes before serving.
