For the Roasted Eggplant: Pre-heat the oven to 375 degrees. Line a baking sheet with parchment paper and set aside.

Place the eggplant cubes on the baking sheet. Drizzle it with olive oil and sprinkle it with salt, black pepper, and red pepper flakes (if using). Give it a toss and make sure that the eggplant is distributed evenly on the baking sheet. Roast in the oven for 30-35 minutes. Be sure to give it a gently toss halfway through the roasting process for even roasting. Set aside to cool.

Do not turn the oven off.

For the Pasta: 10-15 minutes before the eggplant is ready, bring a large pot of water to a boil. Add 1 tablespoon of salt and ziti. Cook until it is al dente, 8-9 minutes. Drain the pasta, place it in a large bowl. Stir in the tomato-basil sauce.

Mix together the ricotta and chopped basil in a bowl and set aside.

To assemble: Spray a large (mine was 9X13) oven-proof casserole dish with vegetable spray, making sure that the sides of the dish is coated with the oil.Place half of the ziti at the bottom of the casserole dish. Spread half of the eggplant cubes evenly on top. Dollop with half of the ricotta-basil mixture and sprinkle with half of the mozzarella.

Repeat the same steps for the second layer: Spread the rest of the ziti and roasted eggplant evenly as a second layer. Dollop with the rest of the ricotta-basil mixture and sprinkle the top with the rest of the mozzarella cheese.

Bake for 30-35 minutes or until the sauce is bubbly and the cheese on top is browned.

When ready to serve, sprinkle it with fresh basil leaves. Serve immediately.
