How to Freeze Food in Jars

When I post pictures of my jar-filled freezer on social media, I get lots of questions about it, usually along the following lines:

  • Is freezing food in glass jars safe? (Yes)
  • Do you use special glass for the freezer? (No)
  • Don’t your glass containers break? (Only that one time…)

I have had little trouble freezing food in glass. I do however take a couple of precautions:

  • Always leave headspace when freezing liquids. I use wide-mouth jars with flush sides for freezing food (i.e., straight sides all the way up to the top). I have broken only one glass container in the freezer. It’s one of those things you do only once. I filled a narrow-neck milk bottle with liquid. Even though I had left head space, when the liquid froze, it expanded and snapped the narrow neck cleanly off the (very nice) bottle. Oops.
  • Don’t overstuff your freezer with jars stacked all over the place sloppily. When you open your freezer door, jars might fall out onto the floor and break.

What I Freeze

Beans. The freeze well with or without liquid. I love having cooked beans on hand in the freezer. I make dishes like chana masala, hummus, spicy black beans, refried beans and more. I dislike the texture and taste of canned beans, not to mention the BPA often present in the plastic lining of canned food. (Click here for directions on slow-cooker beans.)

Sourdough crackers. These freeze very well. They taste so delicious though, they never stay in the freezer long. (Click here for the sourdough cracker recipe.)
