There's an easygoing quality to the sometimes-derided zucchini that Marc Vetri loves. "It's just so versatile," says the celebrated Philly chef-restaurateur, who presides over such restaurants as Vetri, Osteria, and Alla Spina. "It works with everything: fish, meat, salads, or on its own."

Vetri likes to cut them in half lengthwise and grill them. "They eat like a steak, with a fantastic meaty texture," he says. For salads, he shaves it on a mandoline; seasons with salt, pepper, extra-virgin olive oil, vinegar, and fresh mint; and serves it as zucchini "pappardelle," a fresh, light veggie play on the wide ribbon pasta.

In his lasagna with zucchini, Vetri pairs the squash and his exquisite house-made pasta with ultrarich Burrata, a shell of fresh mozzarella with sweet cream and cheese curd at the center. In our lighter take, we combine mozzarella with fat-free ricotta and a little mozzarella liquid to mimic the creamy Burrata texture. Try the original dish at Vetri in June in Philadelphia's Center City East.
