How To Store

Store onions in a cool, dry place, not in the fridge, and not near potatoes. Potatoes give off moisture and a gas that causes onions to spoil faster.

Cooks Tips

The more tears they cause, the more health benefits onions have. To stem the flood while you’re chopping, try chilling onions for about a half hour before cutting, and slice them from the top, leaving the root end intact; it has the strongest concentration of eye-burning compounds.

Be sure to wash onions well before chopping, especially if you’re going to eat them raw. Onions grow underground and can harbor nasty bacteria.

Menu Magic
Like garlic, onions can be added to just about anything. Here are just a few suggestions.

• Add onions to almost any stew or stir-fry.
• To get a bit of raw onion into your diet, combine chopped onions, tomatoes, avocado, and jalapeño peppers for a blood sugar-friendly chip dip. Finish with a splash of lime juice.
• Sauté chopped onions in olive oil and add to corn, potatoes, or peas.
• Add chopped scallions to rice dishes.
• Add sliced onions to green salads.
• Use chopped onions to add crunch to any sandwich salad, such as chicken, tuna, or egg salad.
• Make fruit chutney with peaches, mangos, pears, apples, or apricots and plenty of chopped onion. Serve with meals as a condiment that won’t upset your blood sugar balance.
• Roast some onions to serve as a savory side dish. Cut the root and top from a large onion. Place root side down on a foil-covered baking sheet and bake for about an hour at 400°F (200°C). When it’s done, remove it from the oven and make a deep crisscross cut in the top. Season with flavored vinegar, herbs, sea salt, coarse-ground pepper, and olive oil.
• Enjoy French onion soup, but go easy on the bread and cheese topping. Try adding a few whole grain croutons instead.
• Use caramelized onions to add wonderful flavor to any vegetable and pasta dish. To caramelize an onion, thinly slice onion, then heat 1 tablespoon olive oil in a heavy skillet over medium heat. Add onion and cook, covered, 10 minutes, stirring often. Remove cover and cook for 10 more minutes, stirring occasionally.

Perfect Portion: 1/4 cup
Onions have very few calories, so add them cooked or raw to as many dishes as you can think of. Minced raw onions offer the greatest health benefits.
