Collard Greens

About Collard Greens (Collards)

Collard greens come from the same plant species that includes cabbage, broccoli, and kale.  They have been eaten for at least 2,000 years, likely originating from the ancient Greeks.

Nutrition Benefits of Collard Greens

Collard greens are great sources of Vitamin A, Vitamin C, Vitamin K, Calcium, and Manganese.  Some research has linked Collard Greens to cholesterol lowering, cancer preventative, and anti-inflammatory qualities.

Storing Collard Greens

Store collard greens the same way you would store spinach or other greens: refrigerate in a plastic bag and don’t wash them until you are ready to use them.

Did you know you can freeze collard greens?  Here’s how … start by washing them and cut off any stems.  You should then blanch the collard greens (boil it in water for ~3 minutes and then transfer to ice cold water).  Blanching is meant to kill bacteria, not to cook it.  Once it’s cooled – then place it in a colander or strainer and drain as much water as possible.  Now you can package in airtight containers and store in a freezer!

Smoothie Tip

If a recipe calls for Collard Greens and you don’t have it, try substituting with spinach, kale, or any other dark leafy vegetable.
