Slow Cooker Vegetable Broth

Vegetable Broth Recipe

I will never forget the first time I reached into a friend’s freezer and saw a big bag of vegetable scraps.

There were onion peels, bits of skin from potatoes and carrots, and even a few broccoli stalks all in a large freezer storage bag. What was she doing with those scraps?

She laughed when I asked, then told me she saved all of her vegetable scraps to use in making homemade vegetable broth.

I was surprised and excited to do the same for myself at home. This slow-cooker version has become a favorite way to use up scraps from cooking while providing my pantry with a much-needed ingredient.

What Vegetables Should I Use?

While my friend told me she used pretty much any vegetable, I find that the best broth comes with a solid base of things like onion and garlic.

I add in many vegetables, and a few spices when I make broth, but you can mix and match to find a balance you like.

Below are some ideas of vegetables you can add to your broth.

  • Potato skin
  • Onion skin and pieces
  • Shallot and green onion skins, peels, and pieces
  • Carrot peelings and pieces
  • Garlic peel and whole cloves
  • Celery stalks and leaves
  • Broccoli and cauliflower stalks
  • Mushroom bits and pieces or stalks

Can I freeze this vegetable broth for the future?

100% yes! I absolutely love freezing foods to use in the future, and the broth is one of those items.

This vegetable broth recipe is ideal for making in large batches, then allowing to cool and freezing for later.

I like using mason jars for freezing broth. Use the wide mouth jars so they don’t crack when freezing!

You can also use a freezer soup container or even large plastic freezer bags. Whatever method you choose, make sure to leave extra space in the container as liquid expands some when freezing.

As always, add a label with the date you made the broth, and what it is so you can find it when needed later.
