Cheesy Eggplant and Rigatoni Bake

Step 1

Heat oven to 375 degrees. Cook rigatoni according to package instructions but keep it slightly more al dente. Reserve 1 1/2 cups pasta cooking water, then drain and rinse pasta under cold water, and transfer to a large bowl while you cook the eggplant.

Step 2

Heat 2 tablespoons olive oil in a large, oven-proof skillet over medium. Add half the eggplant, season with salt and pepper, and cook, stirring, until golden brown on all sides, 9 to 10 minutes. Transfer to the bowl with the rigatoni. Repeat with 2 tablespoons olive oil and remaining eggplant and transfer to the bowl.

Step 3

Heat the remaining 2 tablespoons olive oil in the skillet over medium. Add onion and garlic and cook, stirring, until translucent, 3 to 4 minutes. Stir in red-pepper flakes and season with salt and pepper. Add tomatoes and their juices, crushing the tomatoes with your hands as you add them. Cook until the tomatoes are very soft, about 5 minutes. Stir in the reserved pasta cooking water, adding up to 1 1/2 cups as needed to create a silky sauce.

Step 4

If the skillet is large enough, add the rigatoni and eggplant mixture, Parmesan, 1 cup mozzarella and 1 cup basil and toss to coat. Otherwise, add the tomato sauce, Parmesan, 1 cup mozzarella and 1 cup basil to the large bowl with the rigatoni and eggplant, toss to coat and then return to the skillet or transfer to a greased baking dish.

Step 5

Top with remaining 3 cups mozzarella and bake until the sauce is bubbling on the sides and the cheese is melted, about 25 minutes. Top with grated ricotta salata and torn fresh basil to serve.
