How to Freeze Vegetables from the Garden
Freezing is the fastest, most forgiving way to save a garden glut. There is no canner and no special skill, just two steps most people get wrong: blanch first, and freeze loose. Do those and your beans and corn taste close to fresh months later.

Blanch most vegetables first
Blanching is a quick boil followed by an ice bath. It stops the enzymes that would otherwise turn frozen vegetables mushy and off-flavored over a few months. Skipping it is the top reason home-frozen veg disappoints.
- Green beans and broccoli: boil about 3 minutes, then ice bath.
- Corn on the cob: 4 to 7 minutes depending on size.
- Leafy greens: 2 minutes is plenty.
- Peppers and berries: no blanching needed, freeze as is.
Freeze loose, then bag
Spread the cooled, drained pieces in a single layer on a tray and freeze them solid first. Then pack them into bags. This keeps them from freezing into one brick, so you can pour out just what you need.
Press out the air or, better, vacuum seal. Air is what causes freezer burn, so the less air in the bag, the longer the food lasts.
What freezes well, and what does not
Most vegetables freeze well: beans, corn, peas, broccoli, peppers, and shredded zucchini. Tomatoes freeze whole with no blanching for later sauce. What does not freeze: high-water crops like lettuce, cucumbers, and radishes turn to mush, so eat those fresh or use another method.
How long it keeps
In a regular zip bag, frozen vegetables keep 8 to 12 months before quality slips. Vacuum sealed, they keep 2 to 3 years without freezer burn. Either way, label every bag with the date and contents so you use the oldest first.
Questions, answered straight
For most, yes. A quick boil and ice bath stops the enzymes that cause mushy texture and off flavors. Peppers, berries, and tomatoes are the main ones you can freeze without blanching.
Freeze them in a single layer on a tray first, then bag them once solid. They stay loose so you can pour out just what you need.
8 to 12 months in a regular bag, or 2 to 3 years vacuum sealed. Removing air is the key to longer life and no freezer burn.
High-water crops like lettuce, cucumbers, celery, and radishes go limp and watery when thawed. Eat those fresh, or pack cucumbers in a brine instead.
