There have been a lot of requests for blanching veggies as of late so here's an easy timetable to follow. Be sure to check tenderness part way into the blanching guide times because freshness and size of vegetables vary.
Our garden is producing very well this year! To keep up with production we decided to make our own frozen veggies. This is a great way to get fresh and frozen at the same time, with just a few steps.
Before I use many of my vegetables in recipes like pan-fried or oven roasted sides, I will parboil or blanch them. This helps me out in many ways. Precooking will cut down the amount of oil I use altogether by a lot, saving on calories and money.
Blanching Vegetables. All vegetables contain naturally occurring enzymes. In some vegetables, unless these enzymes are deactivated with heat before the vegetable is frozen, the enzymes will continue to break down and age them even at freezing temperatures.
Recently while trying to blanch/freeze 12 lbs. of green beans, I ran out of ice to cool the blanched beans. Instead I used some drink boxes, that I always keep in the freezer to use in lunchboxes to keep food cold until lunch time.

What is the proper time to blanch green beans before freezing? One person said 1 minute and another said 3 minutes. Also, can I put them in a freezer bag or do I need actual freezing containers?
By Missiesue from Munger, MI
Blanch for at least 3 minutes if pre-cut into 1 inch pieces. Longer 3-5 minutes if whole. Plunge them into ice cold water for the same amount of time as you blanched them to bring the temperature down. Drain/dry the beans well before using. Use about 1 gallon of water per 1 lb. of green beans. You can use freezer bags as long as you get as much air as you can out of them. I don't recommend hard containers as the air can cause freezer burn.
Why is it necessary to blanch vegetables prior to freezing? Why can't I just wash, drain, cut, and freeze the raw green beans?
By Jackie
I think you can but the blanching, if I remember correctly helps to keep frost from forming on them. The proper procedure is to blanch them for one minute, plunge them in ice water for a minute then lay them on a towel to dry.
It's to preserve the color, keep crisp yet tender and halts the enzymes that deteriorates the nutritional value of the food during storage. Also, assorted veggies need different amounts of blanching time. For instance, beans should be blanched for 3 minutes, corn on the cob for 4 minutes and beets anywhere from 25 to 50 minutes depending on their size. All varieties of onions and peppers do not need to be blanched.
Blanching vegetables and sometimes fruits is necessary before freezing to destroy enzymes and bacteria that could cause spoilage. It also helps to preserve a vibrant color on the frozen product. Plunging the vegetables in ice water stops the cooking process.
Jackie, I do blanch somestuff like any beans,if you don't they will freezer burn and have a freezer taste. I do know I put corn up this year and I didn't blanch it and eat taste good.
Why do we blanch veggies before freezing?
By Guy T.
To stop the enzymes in the foods. Otherwise the food will continue to ripen and become mush.
