However, it is essential to note that the quality of veggies with a high water content deteriorates after freezing. Such vegetables include mushrooms, peppers, tomatoes, and zucchini. This is because the water in their cells forms ice crystals that ruin their textures. 

Which Vegetables Freeze Well After Cooking?

You can freeze almost all vegetables after cooking. Vegetables that freeze well include peas, corn, cauliflower, broccoli, green beans, carrots, and squash. You can also freeze peppers, onions, celery, herbs, and winter greens like kale, spinach, collards, and chard. 

How Should You Freeze Vegetables?

Freezing vegetables is straightforward. Here are a few tips to follow when freezing your veggies:

Asparagus

  2. Blanch for about four minutes (the duration depends on the size of your veggies).
  3. Drain the water.
  4. Pat the asparagus dry. 
  5. Place the blanched asparagus on a tray.
  6. Freeze until solid.

  2. Place the Brussel sprouts on a cookie sheet. Be sure to freeze the vegetables individually.
  3. Freeze until solid. 
  4. Transfer the frozen Brussel sprouts into resealable freezer bags or plastic containers. Squeeze the freezer bags to remove air. 

Blanching Brussel sprouts is an essential step that helps preserve the vegetable’s nutrients and health benefits. It also keeps them fresh and firm. 

If frozen without blanching, Brussel sprouts develop an unpleasant odor, have a shorter shelf life, and become mushy when defrosted. 

Freezing Brussel sprouts preserves the vegetable for about 12 months.

Onions

  1. Chop or dice the onions to any shape and size of your choice. 
  2. Place the onions in a resealable freezer bag.
  3. Squeeze the air out of the freezer bag, seal the bag, and then freeze the onions. 

If you chop or dice your onions, you do not need to blanch them before freezing. However, blanch them in boiling water for about seven minutes if you intend to freeze whole onions. 

A crucial thing to remember when freezing onions is that you must seal them efficiently to lock in their odor. 

Frozen onions can remain safe for consumption for up to eight months. 

Corn

  1. Shuck the corn. 
  2. Remove the kernels from the cob (if you intend to eat your corn on the cob, then it’s okay to keep it).
  3. Blanch the corn by boiling it in water for about six minutes. 
  4. Drain the water.
  5. Transfer the kernels into resealable freezer bags. 
  6. Squeeze the freezer bags to remove air.

Which Vegetables Cannot Be Frozen?

You should never freeze some fruits and vegetables. These include celery, citrus, cucumbers, green peppers, lettuce, parsley, potatoes, and radishes. 

Celery

When frozen, celery loses texture and crispiness. Its flavor is also affected, making it unsuitable for raw consumption. 

Citrus

Citrus fruits have a lot of water. When frozen, the water in the juice vesicles turns into ice crystals that rapture the vesicles. This makes the fruits dry, deteriorating their flavor and texture. Citrus is more likely to decay after freezing. 

Cucumbers

When you freeze whole cucumbers, they lose their texture and flavor. Additionally, fresh cucumbers become soggy once they are defrosted. 

Green peppers

When frozen, green peppers lose their texture and crispiness. They also become mushy and soggy when defrosted.  

Lettuce

Lettuce has a lot of water. When frozen, the water in the plant cells turns into ice crystals that rupture and destroy the cells. This deteriorates the flavor and texture of the vegetable. Additionally, lettuce becomes mushy when defrosted. 

Parsley

Parsley also has high water content. Ice crystals develop in the plant cells after freezing, destroying the cells and ruining the parsley’s texture and flavor. Additionally, when parsley is defrosted, its bacteria multiply rapidly and break down. 

Potatoes

The high water content of potatoes makes them unsuitable for freezing. When frozen, raw potatoes will become watery, grainy, and mushy after defrosting. Their texture and flavor are ruined by ice crystals that develop when the potatoes are frozen.

Radishes

Frozen radishes lose their rich flavor and texture when thawed. It is therefore recommended to avoid freezing radishes and instead consume them fresh.
