Making homemade vegetable broth in the slow cooker is a simple and easy process. It’s cheap, too, as you can use up veggies that might be seeing the end of their days. Waste not, want not with homemade vegetable stock.
So, what do you do with vegetables that are beyond eating fresh and looking just a little sad? Roasting veggies is a great option for those that are a bit wilted. Turning them into liquid gold is another.
Liquid gold? Say what?
Yep. Vegetable trimmings as well as vegetables that are nearing their lives’ end can still serve a delicious purpose in your kitchen! Make vegetable broth to save money and avoid food waste. It’s so easy when you use a slow cooker, there’s really no reason not to do it.
How to Make Vegetable Broth in the Slow Cooker
What is veggie broth made of?
Vegetable broth is made by simmering water and vegetable trimmings along with salt, peppercorns, and herbs. The resulting liquid can be used as a base for soups or sauces as well as for flavoring in rice dishes.
What vegetables can you use in broth?
You can use the vegetables that you already have on hand, and particularly those that are on their last legs. Kitchen staple veggies are great for making into broth, such as
In small amounts you can also use asparagus and tomatoes. You can also add fresh herbs like parsley and thyme, as well as dry bay leaf.
What vegetables should you not use in vegetable broth or vegetable stock?
It’s often recommended not to use these vegetables as they may make the broth bitter or over flavored or turn it cloudy:
- bell pepper
Honestly? I don’t worry about cloudiness and have used broccoli and peppers in my veggie stock in the past. We liked it just fine. Your mileage may vary.
What is the difference between veggie stock and vegetable broth?
Once upon a time, the difference between a stock and a broth was whether or not bones were used in the preparation. So, if you simmered chicken bones with aromatics you had chicken stock while the liquid left from simmering chicken meat would be called chicken broth.
(Bone broth is just a silly name made up by hipsters.)
Since there are no bones involved in making vegetable broth, technically all liquids made from simmering vegetables would be called broths. However, food has gotten complicated in recent years and so another layer of definition has been added: broth for a finished product and stock when using it as an ingredient.
At the end of the day, vegetable stock and vegetable broth are basically the same thing, and can be used interchangeably.
How do you make vegetable broth taste better?
Have you salted the broth? Salt has often gotten a bad rap, but in reality it brings out the flavor in foods. Try salting the broth first to see how it tastes.
Have you added herbs and seasonings? A little goes a long way, especially when you let it simmer. Try your favorite herb, a few cloves of garlic, and some peppercorns.
Have you used vegetables you actually like? If you don’t like the flavor of tomatoes, chances are good you won’t like broth made with tomatoes. Focus on vegetables you enjoy.
What can you use vegetable broth for?
Vegetable broth can be used in savory recipes wherever water or chicken or beef stock is called for. These plant-based soups are delicious made with homemade vegetable broth:
- Smoky Bean Soup
- Roasted Vegetable Soup with Fresh Oregano
- Lemon and Herb Rice Pilaf
- Mushroom and Onion Gravy
Can you freeze veggie broth?
Since you’re not going to boil up a pot of broth every time you need it, it’s in your best interest to freeze it. Chill the broth after straining out the veggies and divide it into 1- and 2-cup portions. Freeze until ready to use.
Is it cheaper to make your own vegetable stock?
When I make vegetable stock it’s usually because I’ve got some veggies near their life’s end, veggies that might otherwise head to the compost pile. Simmering them in a pot of water with a handful of herbs and spices costs me about 25 cents.
Since store-bought vegetable broth costs anywhere from $1/cup and up, it’s definitely cheaper to make your own, especially if you’re using up what might otherwise be food waste.
Do you need special equipment to make vegetable stock in the slow cooker?
Here are the kitchen tools I like to use for making vegetable stock:
- a slow cooker
- a fine mesh strainer
- 4- cup and 8-cup glass measures
- Souper Cubes or other freezer safe containers for storage
What do you do with the leftover veggies from making stock?
After simmering for several hours, the veggies have pretty much given up all their flavor. Feed them to the chickens or the compost bin at this point.
