Zucchini...Best way I know to freeze it is to grate it on a coarse grater wring it fairly dry and bag it before placing it in the freezer to use in soup...

Eggplant...I've never frozen per se though I did make a lot of caponata one year and I froze that in 2 cup containers to use later in a variety of ways, including soup, appetizer spreads and pasta sauce.

Guide E-320
Revised by Martha Archuleta, Food and Nutrition Specialist
This publication is scheduled to be updated and reissued 1/08.
Fresh vegetables can be frozen quickly and easily
during the harvest season. Whether you freeze purchased
or home-grown vegetables, the keys to a successful
product are using vegetables at the peak of ripeness
and freezing quickly after purchase or harvest.
Selection and Purchase
Choose vegetables that are young and tender. Wash
well and rinse twice in fresh water each time to remove
dirt. Trim away any bad areas, tough stems, and
leaves. Cut into desired sizes.
Although freezing slows enzyme action, it doesn’t
completely halt it. Blanching, a heat treatment to inactivate
the ripening enzymes in vegetables, preserves
their color, texture, and flavor for nine to twelve
months in the freezer.
Except for onions and green peppers, vegetables
should be either water or steam blanched before being
frozen. Some vegetables, such as mushrooms, eggplant,
and summer squash, taste better if sauteed
briefly in oil, butter, or margarine before freezing.
Chill before packing.
To water blanch vegetables, place the washed, prepared
vegetables in a pot of boiling water. Use one
gallon of water for each pound of prepared vegetables.
See table 1 for recommended blanching times
for different vegetables. Start timing the blanching
action when the water returns to boiling after putting
in the vegetables. Plunge the vegetables immediately
into cold (preferably ice) water for the same time as
you blanched the vegetable. This cold bath stops the
cooking action.
To water blanch, place two cups or about 1 pound
of prepared vegetables in a single layer in a basket
and lower into a pot containing one gallon of boiling
water. The vegetables should be above the water.
Cover with tight-fitting lid and start counting blanching
time when steam comes up around the pot lid.
(See table 1 for blanching times.) Plunge vegetables
into a cold bath.
You can use the microwave oven to blanch small
quantities. However, there is no time or money saved
when microwave blanching vegetables.
Packing Food into Freezer Containers
Drain and chill food before packing into moisture
proof freezer containers. Both freezer bags and square
containers provide economical packs with regard to
space used in the freezer.
Fill rigid containers to the expansion line. If you
use freezer bags, lay bags on counter after filling with
drained vegetables and press out air. Close zipper
bags except for about one inch. Use a drinking straw
to suck air out and complete closure. If using a bag
with a twist tie closure, gather edges around drinking
straw and draw out air before twisting and tying.
Date and identify contents using a moisture proof
freezer pen. When freezing, place packages in the
coldest area of the freezer with about one inch around
the packages for cold air circulation until the food is
frozen. After packages are frozen, stack tightly.
Freeze only the amount that the freezer can handle
efficiently. A good rule of thumb is 2 to 3 pounds of
food for each cubic foot of storage space. Overloading
slows the freezing process and adversely affects the
quality of the food, especially corn-on-the-cob.
Make a food inventory and post it close to the
freezer. List foods and number and sizes of containers.
Keep a pen close to mark the list as cartons are used.
Thawing and Preparing Vegetables to Eat
Except for corn-on-the-cob, vegetables can be
cooked with little or no thawing. Corn on the cob
should be thawed completely before cooking. Greens
should be partially thawed and separated before cooking.
Because the vegetables were blanched before
freezing, they will cook quickly.
Use the smallest amount of water possible to conserve
nutrients. Cook only the amount you need for
the meal. Avoid letting vegetables stand after cooking
as nutrients leach into the cooking water.
