If you have an abundance of zucchini and squash from your garden, canning them is a great way to preserve these vegetables for future use. Not only does canning extend their shelf life, but it also allows you to enjoy them long after the growing season has ended. However, since zucchini and squash are low-acid vegetables, it’s important to use the right canning methods to ensure they remain safe to eat and maintain their texture.
Because of their low acidity, zucchini and squash must be processed using a pressure canner. This method helps eliminate harmful bacteria that could lead to foodborne illnesses. According to the National Center for Home Food Preservation, pressure canning is the safest method for low-acid vegetables. On the other hand, if you prefer the water bath canning method, you must increase the acidity of the vegetables by pickling them with vinegar or lemon juice.

Preparing Zucchini and Squash for Canning
Before starting the canning process, it’s crucial to properly prepare the zucchini and squash. Following the right steps not only ensures better results but also helps avoid common canning issues.
1. Selecting the Right Vegetables
To get the best texture after canning, it’s essential to choose young, firm zucchini and squash. Larger, overripe vegetables often contain more water, which may result in a mushy texture once processed.
2. Cleaning and Cutting
- First, wash the vegetables thoroughly under cold water to remove any dirt.
- Depending on your recipe, slice, cube, or shred the vegetables to suit your desired outcome.
3. Blanching for Better Texture
Blanching is an important step that helps preserve the texture and color of your vegetables. Additionally, it helps retain flavor. As discussed in the Zucchini Squash Relish Recipes for Canning Large Batch guide, blanching is also helpful when freezing zucchini.
- Boil the vegetables for 2-3 minutes.
- After boiling, immediately place the zucchini and squash in an ice bath to stop the cooking process.
Best Canning Methods for Zucchini and Squash
There are two main methods for canning zucchini and squash. Depending on your goals, both methods offer different benefits for preserving your vegetables.
1. Pressure Canning
Because zucchini and squash are low-acid vegetables, pressure canning is the recommended method. This method ensures the vegetables are processed at high temperatures, which eliminates bacteria and keeps the vegetables fresh for a long time.
- Be sure to use the correct settings on your pressure canner based on your altitude.
- In addition, following the right timing and pressure ensures your canned vegetables will be safe to eat.
2. Water Bath Canning for Pickled Zucchini and Squash
If you prefer water bath canning, you can still preserve zucchini and squash by pickling them. Pickling increases the acidity, making it safe for water bath canning.
- Prepare a brine made from vinegar, salt, and spices.
- Then, pack the vegetables into sterilized jars and pour the brine over them.
- After sealing, process the jars in a water bath canner for the recommended time.

3. Freezing as an Alternative
While canning is an excellent way to preserve zucchini and squash, freezing can be a simpler alternative. Although freezing may not retain the texture as well as canning, it’s still an effective method for storing your vegetables for later use.
- First, blanch the vegetables to help maintain their color and flavor.
- Then, drain them well and pack them into airtight containers or freezer bags.
