Roasting vegetables in a single layer on a baking sheet.


Expert Tips from the Taste of Home Test Kitchen

  • Roasting is a dry-heat method of cooking that makes the flavor of vegetables rich and sweet. Root vegetables are a long-standing favorite, but you can also roast corn, squash, onions, garlic, eggplant, broccoli, hearty greens and most other vegetables. Scroll down for tips on roasting different vegetables.
  • To roast several different types of root vegetables at the same time, cut those with similar densities in uniform pieces so they cook evenly. Cut denser vegetables such as carrots and potatoes into smaller pieces so everything's done at the same time.
  • Roast veggies in a single layer in a heavy, shallow-sided roasting pan, like a jelly roll pan. If the pan is too small or the vegetables too crowded, they’ll steam, and you want them to be crisp.
  • Coat veggies with a little Italian salad dressing, butter or olive oil, and try different herbs or seasonings. Think lemon-pepper, Italian, salt and pepper. Just give them a quick toss before roasting.
  • For uniform browning, give the vegetables a quick stir about halfway through cooking.
  • Vegetables are done with they're tender and easily pierced with a fork or knife.
