Yield: 4 servings
Ingredients: Olive oil; 1 large onion, small diced; 1 tablespoon minced garlic; 1 1/2 cups peeled, seeded, chopped tomatoes; 1 tablespoon minced thyme leaves; Salt and freshly ground black pepper; 2 teaspoons sugar; 3 Japanese eggplants, peeled in alternating 1-inch strips, leaving some of the skin on, sliced diagonally into 1/4-inch thick slices; 3 small zucchini, ends trimmed, and sliced into 1/4-inch thick rounds; 1 cup grated mozzarella; 1/4 cup grated Parmesan

1

In a large saute pan set over medium heat, add enough olive oil to lightly coat the bottom of the pan.

2

When the oil is hot, add the onions and saute until translucent, but not browned, about 5 minutes.

3

Add the garlic and cook for 1 minute, stirring.

4

Add the tomatoes and cook until they start to give off their liquid, about 5 minutes.

5

Add the thyme and season with salt and pepper.

6

Add the sugar and cook until there is almost no liquid left, about 10 to 15 minutes, stirring frequently.

7

Remove from the heat.

8

Preheat the oven to 450 degrees F.

9

Lay the eggplant and zucchini out on a flat surface and season with salt and pepper.

10

Drizzle with olive oil.

11

In another large saute pan set over medium high heat, add enough olive oil to coat the bottom of the pan.

12

When the oil just starts to smoke, add the eggplant in 1 layer and cook just until golden brown on both sides, about 2 to 3 minutes per side.

13

You might need to do this in batches.

14

Remove to a paper towel lined plate.

15

Blot the top with additional paper towels.

16

In the same pan, add more olive oil to coat the bottom of the pan.

18

Remove to a paper towel lined plate.

19

In a shallow roasting pan or baking dish, spread half of the tomato sauce evenly over the bottom.

20

Begin layering the eggplant and zucchini along the outside of the baking dish so they are overlapping slightly.

21

Continue until the pan is full and the eggplant and zucchini is used.

22

Cover the top with the remaining tomato sauce, spreading evenly.

23

Sprinkle the mozzarella and Parmesan evenly over the top, covering completely.

24

Place the baking dish inside a large baking dish.

25

Pour hot water into the larger baking dish about half way up the sides to make a water bath.
