Vegetable stock is a liquid made from water and vegetables. The exact vegetables vary, but are most commonly some combination of onions, celery, carrots and herbs.
Are vegetable broth and stock the same thing?
Broth is an old world term that just means “boiled” so yes, broth and stock are the same thing. They are both a liquid simmered to make a vegetable infused water.
What do you use vegetable stock for?
Most commonly soups, but you can also use it in pasta, casserole, as the water base for rice, barley and farro, gravy and even dressings and marinades.
Using stock in boiling water for pasta, rice and potatoes is one of my secrets to more flavorful foods.
How to Make Vegetable Stock
The most basic way to make stock is to start with a large stock pot of water, then add desired vegetables, spices and herbs.
Bring to a very low simmer and allow to heat for several hours. The longer it has to heat, the more developed the flavor.
Strain out all of the solids and you are left with vegetable broth.
What is vegetable concentrate?
Basically it is just stock/broth that is super reduced until it is a paste form and has high flavor potency. When combined with water, the potency reduces to more mild form.
You can also find bouillon, which is a granulated version of concentrate.
Both of these are great ways to always have vegetable stock on hand.
What can I substitute for vegetable stock?
You can also jazz up your water by adding garlic or onion powder and other dried herbs and spices like parsley or basil.
Storage and Freezing
Homemade vegetable stock will last in the fridge for 3-4 days. Make sure you shake or whisk well before adding to the desired recipe to reintegrate all the ingredients.
Stocks are also easily frozen to be used at a later date. Simply let it cool and pour it into plastic freezer bags. It will stay good for up to 1 year.
