2 tablespoons olive oil
2 fennel bulbs, cut horizontally into 1/3-inch thick slices, fronds reserved
Salt and freshly ground black pepper
1/4 cup freshly shredded Parmesan

Directions
Preheat the oven to 375 degrees F.

Lightly oil the bottom of a 13 by 9 by 2-inch glass baking dish. Arrange the fennel in the dish. Sprinkle with salt and pepper, then with the Parmesan. Drizzle with the oil. Bake until the fennel is fork-tender and the top is golden brown, about 45 minutes. Chop enough fennel fronds to equal 1 teaspoon, then sprinkle over the roasted fennel and serve.
