Instructions
Heat the broiler
Either use a broiler pan or line a sheet pan with foil, and place the eggplant slices in a single layer. Brush eggplant with olive oil on both sides and season with salt and pepper. Broil eggplant till golden and browned, approximately 8 minutes on the first side and 6-7 minutes on the other side, total broil time is 14-15 minutes. Remove eggplant from the oven and set aside.
While eggplant is cooking, mix together the custard ingredients in a medium-sized bowl - ricotta, egg, half-and-half, 1/4 cup of the Parmesan, 1/8 teaspoon salt, and 1/8 teaspoon pepper.
Next, preheat the oven to 400 degrees F and lightly grease or spray an 8-9" baking dish or two large-sized individual gratin dishes.
Now it's time to assemble the gratin. First place a layer of eggplant slices in the baking dish (photo #1), next sprinkle with Parmesan, salt and pepper and spoon on marinara sauce (photo #2). Then add a second layer of eggplant, more salt and pepper (photo #3). Finally, add the ricotta mixture and 1-2 tablespoons Parmesan on top (photo #4).
Place gratin in the oven and bake until the custard is set and the top is browned, approximately 25 to 30 minutes. Serve warm.
