Q. Can you freeze Swiss Chard? Does it lose nutritional value?
A. Yes, you can freeze Swiss Chard. Cut off stems, rinse, blanch them, cool in water bath, and then store in freezer Ziploc bag. (To blanch, bring pot of water to boil and submerge greens for 2-3 minutes.) Freezing does not cause a loss of nutrients and in fact is a great way to preserve their nutrition.
