This post is the second in my garden freezing series, where I’m sharing three simple ways to preserve the harvest:
- easy no-blanch freezer foods,
- blanch-and-freeze vegetables, and
- cooked vegetables for the freezer.
In this post, I’m covering the next step — the simple process of blanching and freezing garden produce.

Why I Freeze Broccoli
I love harvesting vegetables from the garden and putting them up for later. There’s something satisfying about knowing summer’s work will carry us through the colder months. One of my favorite ways to preserve vegetables is by blanching and freezing them, and broccoli is one of the easiest places to start.
I usually plant far more broccoli than our family can eat during the summer, which makes it a perfect candidate for the freezer. The same method also works well for other garden vegetables like green beans, cauliflower, and carrots, depending on the vegetable and how it holds up to blanching.
How to Blanch Broccoli
I start by harvesting broccoli heads when they are ready, then cut them into bite-size pieces with some stem attached and soak them in cold water. While the broccoli is soaking, I bring a large kettle of water to a boil.
Once the water is boiling, I add the broccoli and blanch it for 2.5 minutes. Then I remove it immediately and plunge it into icy water to stop the cooking process. This helps preserve the broccoli’s color, flavor, and texture for long-term storage by slowing the enzymes that can cause spoilage and off-flavors.
How to Freeze Broccoli
After the broccoli has cooled completely, I spread it out on a cookie sheet and place it in the freezer overnight. This step keeps the pieces from freezing into one big clump, so I can easily grab just what I need later. Once frozen, I transfer the broccoli into quart- or gallon-size freezer bags and store it in the freezer until I’m ready to use it.
Frozen broccoli is one of my favorite vegetables to pull out in the middle of winter. I use it in dressed-up ramen, soups, stir-fries, and as a simple side dish with dinner. It never seems to last until the next harvest season. Even with my best efforts, we usually run out by February, right around the time I’m planting broccoli again from seed.
Other Vegetables to Blanch and Freeze
The same basic blanch-and-freeze method works well for other vegetables from the garden too. Green beans are a freezer favorite, and I also like to preserve cauliflower and carrots when we have extra. If you grow a garden, freezing vegetables this way is one of the easiest ways to avoid waste and enjoy your harvest later in the year.
Blanching Guide for Garden Vegetables
If you like having a quick reference, here’s a simple blanching guide for a few common garden vegetables, along with the kinds of dishes they work best in after freezing.
| Vegetable | Blanch Time | Freezer Life | Best For |
| Broccoli | 2.5 minutes | 8–12 months | Roasting, soups, stir-fries, side dishes |
| Green beans | 3 minutes | 8–12 months | Side dishes, casseroles, sautés |
| Cauliflower | 3 minutes | 8–12 months | Roasting, soups, mash, casseroles |
| Carrots | 2–3 minutes | 10–12 months | Soups, stews, roasting, glazing |
| Brussels sprouts | 3–5 minutes | 8–12 months | Roasting, skillet dishes, side dishes |
Blanch times can vary a little depending on the size and freshness of the vegetable, so use this as a starting point. When I freeze vegetables, I usually label the bag with the date so I can keep track of what needs to be used first.

In my next post, I’ll cover how to freeze garden vegetables that you fully cook first, such as sweet corn, beets, and squash.
