How to Make Vegetable Broth from Scraps

Time to stock up on broth

Right now, fresh produce is plentiful and we’re enjoying nature’s bounty. Although it’s not soup season yet, we in the North know that “winter is coming.” (You’re right, still haven’t let go of Game of Thrones). In winter, we need soup. And every good soup starts with soup broth, so, make room in your freezer and  let’s “stock” up on vegetable broth!

I use ridiculous amounts of vegetable broth all winter long, so I was really pleased when I found this simple way to make my own. The recipe comes from the Thug Kitchen cookbook (yes, you read that right), which, by the way is a super-entertaining read. Warning: The cookbook uses a lot of profanity, their trademark (Full name: Thug Kitchen: Eat Like You Give a F***). Aside from that they provide straightforward ways to make plant-based meals for all tastes.

Start saving vegetable scraps

To make this broth, start saving your vegetable scraps. Think ends of onions, celery, carrot peels, bell peppers, and shriveled up tomatoes – anything “broth-worthy.” Nothing bitter, like broccoli or brussels sprouts. And nothing that’s moldy or starting to rot.

Store the scraps in a one-gallon Ziploc bag in the freezer and add as they accumulate. When the bag is full, get ready to make some broth.

broth ingredients in slow cooker

I use the biggest pot I have, a 12-quart stock pot. Dump the frozen scraps in the pot and then fill with water. Season with some salt and pepper and 2-3 bay leaves. Bring the pot to a boil, reduce heat and let the liquid simmer for one hour. Turn off the heat and let pot cool.

Straining and storage

The straining and storing of the broth requires the most time and attention. Basically, the veggie scraps need to be strained out and the broth should be frozen for future use. TK says cheesecloth strains well, but I’ve always used a colander and mesh strainer.


I pluck all the large pieces out of the pot and place them in a colander over a large bowl. These I just let sit to drain while I deal with the liquid.

The liquid is, of course, our end game. I place a mesh strainer over my largest (8 cup) Pyrex measuring cup and start straining the liquid into the cup. The mesh will remove any remaining chunks, leaving just liquid.

frozen broth in busted jars

The first few times I made broth I froze it in quart-sized glass mason jars. I found out the hard way that these are not freezer safe. 😖

Now I use plastic screw-cap jars.

No breakage yet, and this is the fourth batch I’ve made. I think I’ll stick with this mode. They are BPA free and come in both pint and quart sizes. Very handy.

Dealing with the expansion issue

At first I had to tinker with the expansion problem. As we (unfortunately) know, liquid expands when it freezes and it sometimes freezes in weird shapes.


This was a previous batch of broth.

As an experiment, I left the lid loose when I placed the containers in the freezer to allow for these “ice sculptures.” Then, I “shaved” the tops from the bubble in the middle to get the lid on. It got the job done, but was kind of a pain. Yes, I thought of just underfilling the containers but that seemed counter-productive – a quart of broth should be a quart of broth, darn it!

jars half filled with vegetable broth

So, I arrived at a different solution. I filled the containers halfway with broth and put them in the freezer, and put the rest of the broth in the fridge.

The next day, I removed the freezer containers and finished filling them with broth and put them back in the freezer. It’s a few extra steps, but this way I get full containers that aren’t bursting.

For someone like me who uses a lot of broth for cooking, this is a very cost-effective and fun way to D.I.Y.!
