Dry fresh, crisp broccoli for use as a nutritious snack or to reconstitute and use in a variety of recipes. Michigan State University recommends using one of two methods -- an oven or dehydrator -- to dry your broccoli. Both yield similar results, but use whatever method you have the tools for, since you probably have an oven, but may want to save the expense of buying a dehydrator.

Trim the broccoli heads off the stalks with a clean, sharp knife.

Cut the stalks lengthwise into four pieces each.

Wash the broccoli pieces under running water.

Place the broccoli in a pot of boiling water for three to four minutes to blanch. Remove from the water and set aside while you ready the dehydrator.

Open the top of the dehydrator, remove the trays and layer the broccoli pieces on the trays. Keep them separated so they do not overlap.

Replace the trays back in the dehydrator and place the lid back on the top.

Select the appropriate dehydration temperature, based on the manufacturer's suggestions. Most suggest drying fruit and vegetables at temperatures between 130 degrees Fahrenheit and 140 degrees Fahrenheit.

Plug the dehydrator's power cord into an electrical outlet and switch it On; some models automatically switch on when plugged in.

Dry the broccoli for about five to seven hours or based on the manufacturer's directions. Some manufacturers recommend turning off the fan and allowing the broccoli to dry for about two days.

Trim the broccoli heads and cut the stalks into four pieces each with a sharp knife. Wash the broccoli pieces. Place the broccoli in a pot of boiling water for three to four minutes. Remove from the water and set aside.

Preheat your oven to its lowest setting -- a warm setting or below 140 degrees Fahrenheit.

Layer the broccoli pieces evenly on a non-stick pan.

Place the tray in the oven and keep the door propped oven. Ideally, situate a fan in front of the oven to increase airflow; keep it running on low while the broccoli dehydrates.

Keep the pan of broccoli in the oven for about six to eight hours. Watch for signs of dehydration; the broccoli should appear brittle.
