Can You Freeze Eggplant?

Also known as aubergine or brinjal, the versatile eggplant can be used in casseroles, soups, curry, stir-fry, and as a dip. Although commonly used as a vegetable, eggplant is botanically classified as a fruit.

These purple egg-shaped fruits don’t last very long and discolor quickly once sliced due to oxidation. This makes it tricky to keep more than what you require for a meal or 2 in stock.

If you’ve got a big harvest or have more on hand than you need, the best way to preserve eggplant is by freezing it. Due to its high moisture content, there are a few things to consider when storing eggplant in the freezer.

Here is a full guide to freezing eggplant.

Types of Eggplant

The most common type of eggplant has purple skin, an oblong shape, and a spongy cream-colored interior with small seeds. Eggplant is generally eaten cooked. The skin and seeds are also edible once prepared.

Cooking allows the spongy flesh to absorb oils and flavors, making it a great base for a variety of cuisines and flavor profiles.

Eggplant also comes in speckled and white-skinned varieties, in various sizes and lengths. 

Regardless of the type of eggplant you use, it can be steamed, roasted, stewed, stir-fried, pan-fried, battered and deep-fried, curried, or pickled. Eggplant can also be stuffed and is often used in sauces or dips.

Can Eggplant Be Frozen?

Freezing eggplant is one of the best ways to prolong its shelf life, however, it is important to note that due to its naturally high water content, the eggplant won’t be firm once the formed ice crystals defrost after freezing.

Considering that eggplant is generally only eaten cooked, the textural change will not be very noticeable.

If the eggplant seems too watery once thawed, it will still be ideal for use in dips, curry dishes, pasta sauces, and soup. Eggplant which you intend to fry at a later stage can be breaded before freezing.

Only freeze fresh, completely ripe eggplant with a firm texture. Eggplant that has started to wrinkle or develop soft spots should be used immediately or thrown away as it will not freeze well.

Although all eggplant types can be frozen, the traditional black or dark-purple varieties hold up best in the freezer compared to the smaller purple Chinese and Thai types.

How To Freeze Eggplant

Option 1: Raw

Step 1: Clean

Wash the eggplant to remove any dirt and dry it with a clean dishtowel. Cut off the top stalk and bottom end of the eggplant. Peel the eggplant if preferred, however, this is optional depending on how you wish to use it after freezing.

Step 2: Slice

Cut the eggplant into slices approximately 1/3 inch thick. 

Step 3: Blanch

Blanching is important to prevent color and flavor loss. The heat destroys ripening enzymatic activity which causes the eggplant to slowly deteriorate over time. 

The point of blanching is, however, not to fully cook the eggplant as you still want the texture to remain firm.

Adding lemon juice to the blanching water will prevent discoloring.

Bring a pot of water to the boil and add ¼ cup of lemon juice for every 2 liters of water. Place the eggplant into the pot of boiling water for 4 minutes. Keep a separate bowl of ice water nearby. 

After 4 minutes, drain the eggplant and immediately place it into the ice water to stop the cooking process.

Step 4: Dry

Once completely cooled, drain the eggplant slices and dry them lightly. Additional moisture on the eggplant will form large ice crystals on freezing and further damage the texture, resulting in a soggy thawed product.

Step 5: Pack

Divide the slices up into the desired portion sizes you may want to use at any given time. Place each portion of the slices into a resealable freezer bag. Press out any air at the top of the bag before sealing.

Step 6: Label and Freeze

Label the bag with the date and place it in the freezer. This will help you to keep track of how long the eggplant has been stored in the freezer.

Option 2: Puree

When using the eggplant in a dip, sauce, or soup, freezing it pre-cooked in a puree is the most convenient and sensible option.

Step 1: Wash and Prick

Wash the eggplant and cut off the top green stem. Using a fork, prick the eggplant skin a few times to prevent it from bursting while cooking.

Step 2: Cook

Roast the eggplant whole until it is soft. Alternatively, you can also steam the eggplant.

Step 3: Cool

Let the eggplant cool down completely. To speed up the cooling process cut the eggplant in half lengthwise to allow the steam and heat to escape.

Step 4: Pack

Once cooled and halved, scoop out the flesh of the eggplant. Place the soft fleshy puree into resealable freezer bags. Do not overfill the bags as you do not want to risk them bursting during the freezing process.

Step 5: Seal, Label, and Freeze

Seal the bags by pressing out any remaining air. Label each bag with the date of freezing as well as the contents and place it in the freezer.


How To Thaw Frozen Eggplant

Eggplant which has been sliced can be cooked from frozen. Remove the frozen slices and place them directly into the pan, pot, or stir-fry for cooking.

Eggplant puree can be used directly from frozen if adding it to a soup or casserole.

If you need to defrost the eggplant for use in a dip or puree, thaw it overnight in the refrigerator or place the sealed bag in a bowl of room-temperature water to speed up the thawing process.
