ROASTING VEGETABLES & FRUITS

By Debra Daniels-Zeller

Many people know roasted vegetables taste better, but what does roasting mean? It has a long history, according to Barbara Kafka in Roasting: A Simple Art. Roasting started as an "open-air activity with a hand-turned spit revolving over a fire," and later, when roasting moved indoors with ovens, the techniques changed.

According to most chefs, roasting is mostly high-heat cooking (400 degrees or more) with no water added. A light coating of oil before cooking will help caramelize vegetables and helps prevent them from sticking to the pan. Every vegetable roasts a little differently. Peppers can take broiler heat, but extra-thin slices of vegetables, tomatoes, and leafy greens require lower heat. Kale can burn easily and is best when roasted at 200 degrees. For many vegetables, when the heat is turned down, they cook but don't develop the crisp browned exterior. When water is added or a cover is placed over the vegetables, they steam and lose the sweet tones.

Some chefs suggest parboiling dense vegetables like russet potatoes before roasting to ensure the vegetable is cooked inside when the outside becomes crisp. Parboiling is like blanching and means the vegetables are plunged briefly in a large pot of boiling water (not more than 3 minutes). This technique softens food so when the outside browns the inside is soft. Parboiled vegetables are slightly sweeter, and if you cut vegetables thin, consider parboiling as an option to try, rather than a rule to follow.

When roasting fruit, remember any fruit that can be grilled can be roasted. For best results, choose firm varieties like apples, pears, mangos, and pineapples. Unlike with vegetables, oil isn't necessary to bring out sweetness, and adding liquids to fruit before roasting is encouraged. Garnish or drizzle with chocolate sauce or maple syrup. Try chocolate chips and crushed nuts as a topping.

Roasting basics:

  • Preheat the oven according to the recipe. Lightly oil a cookie sheet or 9 x 13-inch cake pan.
  • Cut all vegetables to the same size.
  • Blend herbs like rosemary, thyme, sage, or garlic into the oil before coating the vegetables, if desired. One Tablespoon of oil is plenty for a 9 x 13-inch pan of vegetables.
  • Spread vegetables in one layer. Whole vegetables take longer than diced vegetables. Add quick-cooking veg- etables like zucchini or tomatoes last.
  • Turn vegetables when they are lightly browned, about every 10 minutes.
  • Add salt and pepper to taste before or after cooking.

Vegetables are done when they are fork tender.

Serve the vegetables with salt and pepper or add a sauce or vinaigrette for a gourmet touch. You can also make roasted vegetables the star attractions in main dishes, sandwiches, salads, or soups.

Roasted Kale Chips

(Serves 4)

Kale chips can burn quickly when roasted at high temperatures. The low temperature in this recipe means the kale won't burn and chips are perfect every time.

  • One bunch kale, middle stems removed
  • 1-1 ½ Tablespoons extra-virgin olive oil
  • Salt and freshly ground pepper to taste

Preheat oven to 200 degrees. Lay parchment paper on a baking sheet. Tear kale into bite-size pieces and toss with oil, making sure a little oil coats each leaf. Spread on parchment paper. Sprinkle lightly with salt and pepper. Roast for 30 minutes, turning every 10 minutes to ensure even roasting. If chips are not crisp, continue baking until they become crisp, checking every 5 minutes.
