How to Make Vegetable Broth in a Slow Cooker

If you are going to make broth in a slow cooker, you need to be prepared to use it for dinner. If you don’t not only will your senses revolt, but so will your family. The aroma of broth cooking a in a slow cooker permeates the entire house and as my daughter says  “deceptively smells like food”. So after making a batch of vegetable broth, I usually use some of it to make Minestrone Soup with Quinoa Pasta.

Making your own vegetable broth is very frugal, especially if you use veggies from your garden. It is easier to make than bone broths, because you don’t have to worry about the bones or the fat.

  1. Yum, I love homemade vegetable broth! It snowed here in Vancouver last night, I think some nice warm soup would be perfect today.

  2. Tiffani Jacques says:

    How long does this broth last for if I choose to refridgerate or freeze it for future use?


  3. virginia miller says:

    Vegetable broth sounds wonderful, but what do you do with all the good veggies after the broth is made? Stew perhaps?

    • I put the leftover veggies in the compost pile. They are mushy and most of the nutrients have been transferred to the broth.

  4. This broth is so good! It’s hard to make very flavorful vegetable broth with no salt, but this is definitely my new favorite. In the process in making the Minestrone and hope it is just as flavorful. Thank you for the recipes!!

  5. Have normal size slow cooker (Hamilton Beach Stay and Go)after placing all ingredients in the pot it would only fit 8 cups of H20. Could the 16 cups be a misprint? thank you

    • Hi Kelly, I am pretty sure I can fit 16 cups in my slow cooker, but I could have made a mistake. I will check when I get home. In the mean time, I think it would be just fine to go ahead an make it with 8 cups of water. If you find it is too strong at the end, you can always add water to the final product to achieve the desired flavor.

  6. I love making homemade vegetable broth in the slow cooker! I make mine using my veggie scraps when I chop vegetables for other meals and salads!

  7. Can this be canned in either a pressure or water bath canner?
