  1. Preheat the oven to 450°F (230°C). Prepare the vegetables as directed below. Toss the prepared vegetables in 1-2 tablespoons (15-30 mL) of olive oil and garlic, pressed.
  2. Arrange the vegetables in a single layer on a pan, such as the Stone Serving Tray or Medium Stone Bar Pan (do not crowd vegetables on the pan); season with salt and coarsely ground black pepper, if desired.

  3. Roast the vegetables according to the time indicated on the chart or until tender, deep golden brown, and beginning to caramelize.

Cook's Tips:

Roasting vegetables intensifies the flavor by using high heat and allowing the natural sugars in the vegetables to caramelize. Make sure not to crowd the pan or the vegetables will steam rather than roast.

For variety, create a medley of roasted vegetables by combining 2-3 vegetables from the chart that have the same roasting time.

After roasting, try adding fresh snipped herbs such as basil, oregano, parsley, or chives. For heightened flavor, add a splash of balsamic vinegar.

Present your favorite selection of roasted vegetables on a large platter for a simple and colorful appetizer. Serve at room temperature with assorted cheeses and fresh, crusty bread.
