How to Freeze Swiss Chard

Last Updated: December 17, 2022 References Approved

Swiss chard is a very nutritious leafy green. It is used raw in tossed salads, and it can also be cooked like spinach, kale, or collard greens. If you have a lot of chard and you don’t want to waste any, you can preserve it by blanching and freezing it for up to a year.

Prepping the Swiss Chard

1
Rinse your Swiss chard in cold water. You can mix rainbow chard with green or white varieties. Plan to freeze the chard within 6 hours of picking to preserve nutrients.
- If you are picking it from your garden, cut it at the base of the stem in the early morning for best results.^{[1]

- To remove the excess of water, spin the chard, shake it, or pat it dry.

Chop your Swiss chard. How you chop it will depend upon your preference for preparing it.^{[3]

Research source} You can cut them into long ribbons or small squares.
- Ribbon it by rolling the leaves vertically. Slice horizontally against the rolled leaves in 1-inch (2.5 cm) strips.
- Chop the leaves like you would spinach. Stack the leaves on top of each other. Slice them 2 times vertically. Stack them again and slice them 3 to 6 times horizontally, depending upon the size of the leaves.
- Slice them in half or into fourths, if you like larger sized leaves.

Blanching Swiss Chard

1
Set a large pot of water to boil.^{[4]

Research source} Use a stockpot instead of a saucepan to ensure you have enough space for even blanching.
- Blanching halts enzyme production. It stops the plants from ripening for several days to several weeks. It is recommended to preserve nutrient content for all leafy greens if you can’t use them within two days.^{[5]

Fill a large bowl with cold water. Add 2 to 3 cups of ice cubes. Set your ice bath on a counter near the stove.

Bring the water to a roiling boil. Add your Swiss chard leaves to the water. If you have more than 4 cups of Swiss chard, do it in several batches.
4
Set the timer for 2 minutes. Remove the leaves with a slotted spoon after the timer beeps. Place it directly in the ice bath.
5
Remove the Swiss chard from the ice bath after 2 minutes.^{[6]

Question

Can I steam chard to freeze instead of blanching?

Michele

Top Answerer

Blanching can be completed using boiling water, steam or a microwave oven. To steam, place the chard in a wire basket over rapidly boiling water, cover and start your timer. Steaming takes one and a half times longer than boiling. Microwaving is good for some vegetables, but not recommended for leafy greens. In any event, make sure to have your icy water handy, that's what preserves the color and texture prior to freezing.
