Onions

Grow.

• Start with small bulbs less than ¾-inch in diameter. Plant 2-4 weeks prior to last spring frost. Plant bulbs about one inch deep and 2-4 inches apart in full sun. Onions have a shallow root system that needs consistent moisture and weed control. Water with 1-2 inches of water per week.

Harvest.

• Harvest onions when the tops have fallen over naturally and papery skins have formed. Remove tops and place in mesh bag in a cool, dark space for 2-3 weeks to dry.

• Onions should be firm and have little-to-no scent. Avoid bulbs with cuts, bruises, blemishes or mold. When purchasing whole, peeled onions, select ones with an outside layer that does not show signs of dehydration or mold.

• Onions will keep longer if not washed until just prior to preparation. Whole, dry bulb onions should be kept in a cool, dry, dark place with plenty of air movement. Do not store onions in a plastic bag. Refrigeration is only necessary when trying to extend the shelf life of sweet or mild onion varieties with high water content. Whole peeled or cut onions should be refrigerated after purchasing.

• Most vegetables are rich in fiber and phytochemicals, but provide negligible amounts of saturated fat, trans fat, cholesterol, and sodium and are gluten-free. Onions have only 32 calories per half-cup serving.

Caramelize.

• Heat pan on low, add oil to coat bottom of pan, add 1/4- to 1/2-inch thick slices of onion. Sweat onions in a covered pan until soft and translucent. Remove lid and increase heat to medium. Start stirring when onions begin to brown on bottom, then sauté until onions are soft and brown.

Grill.

• Peel and cut onions into slices or wedges. Cover grill with foil and poke small holes in foil. Pierce onions with a skewer, if desired and place over medium heat. Cover with a foil pan and grill for 15-20 minutes or until tender.

Raw.

• Add onions to salads, sandwiches, burgers, tacos, salsas and relishes

Sauté.

• Heat pan to medium, add oil to coat bottom of pan, add 1/4- to 1/2-inch thick slices of onion. Cook onions about 8-10 minutes or until brown.

Steam.

• Add sliced, quartered or large diced onions into steamer or pan of boiling water. Steam until tender.

Roast.

• Place sliced, quartered or small onions in a roasting pan. Drizzle lightly with oil. Roast with other vegetables or herbs and spices, if desired, for 20-30 minutes at 4000F. Roasted onions can be added to other dishes for additional flavor.
