Dump your vegetable scraps into the bowl of your slow cooker or a large pot.
Fill the slow cooker or pot with filtered water.
Add sea salt.
Add herbs and spices and mix well.
Close the lid and set the slow cooker to the LOW setting for 6 - 8 hours. For stove top, simmer 1-2 hours at low to medium heat.
Strain your stock into a large bowl or directly into a soup.
Pour your stock into jars leaving 2 inches of headspace to allow for expansion if freezing. (I like to strain a second time to catch any scraps that may have gotten through).
Screw the lids on tight and refrigerate your homemade vegetable stock for use that same week. Otherwise, place the jar(s) upright in the freezer.
