Can You Freeze Celery?

I will do a cleansing diet next week. It involves eating fresh produce and vegetable soup. The soup recipe calls for onions, tomatoes, and celery. While I can buy onions and tomatoes per piece, the supermarket sells celery in heads. I just need 4 to 5 stalks. I wonder if there is a way to keep the unused celery in the freezer so I can use in on other dishes in the upcoming weeks, instead of letting it go to waste. 

Celery is really a popular diet food and ingredient. This vegetable is low in calories. It has high water content, and is also rich in fiber, vitamins, and minerals. As an aromatic, it adds flavor, fragrance, and depth to food.

Freezing celery, when blanched, can preserve its color, taste, and most of its nutrients. You can also freeze it raw, though this shortens the shelf life and can make the stalks taste bland. Whether blanched or raw though, freezing makes the celery lose its crispiness and turn limp and mushy.

Can You Freeze Celery

Celery is 95% water. As with other fruits and vegetables with high water content, celery becomes mushy when frozen and thawed.

Because of this, defrosted celery is not good to use as garnish or relish, or as an ingredient for stir-fry and grilled dishes. Use it instead in soups, sauces, casseroles, smoothies, and other dishes that do not require some crispiness on the part of the celery.

You can freeze blanched or raw celeries. Blanching celery kills bacteria, helps preserve and lock in flavor, and lengthens the storage life.

The only downside to blanching is that this process makes the celery lose about a third of antioxidants and water-soluble vitamins such as Vitamins A and C. Fat-soluble vitamins, minerals, and dietary fiber are not affected by the freezing process. It may seem tricky because there is a trade-off between flavor and shelf life on one hand, and nutrient on the other hand. In the end, it is up to you.

You can keep raw celery in the freezer for 2 months, while frozen blanched celery can last for 12 to 18 months. You can put frozen celery directly in the hot dish or smoothie. No need to thaw.

There are also other ways of preserving celery. You can wrap celery in paper towels or in foil, and store inside the refrigerator for about 3 to 4 weeks. You can even freeze celery in oil in ice trays, along with other herbs and aromatics. Or, if you have a green thumb, you can opt to replant the root end of the celery. As for the celery leaves, you can freeze it along with the stalks. You can also freeze it in oil or turn it into a celery pesto.
