I have tried many vegetarian or vegetable stock recipes that leave you wishing for fatty skin and cartilage. It took some time but I found a solution. This all-purpose broth can be frozen or keeps in the fridge for up to a week.
The recipe that follows always works for me because I always keep the ingredients on hand, but whatever vegetables you happen to have laying around will work just as well. If you do not have a bottle of black or white truffle oil then go BUY ONE! It’s hard to substitute for its use and it has many other practical uses like as dipping oil or to add flavor to any bland soup.
A short list of things I would suggest you add, pending their availability and the season, are potatoes, parsnips, zucchini, squash, any type of mushroom, cayenne peppers, bell peppers and any fresh herbs. I have had great luck with all of them. Note to fresh bay leaf users: fresh bay leaves impart a very ethnic taste to stock, so use only half or a quarter of the leaft at a time. Also, any high-quality flavored oil will add depth.
A cookbook from the 1700′s that I recently read said that people used to go crazy over the broth from boiled potatoes. We just throw it out after cooking them, but i suppose we should save it. The potato broth adds more texture than it does taste but it’s a great alternative to corn starch. I suggest adding potatoes to the broth if a recipe calls for a thickening powder, like arrow root or cornstarch.
I have made this broth with whatever quantity of vegetables I have in the fridge before a long weekend away or when any veggie is too ripe to eat raw. In other words, it’s a great use of vegetables that would have otherwise gone straight into the garbage.

Vegetables ready for soup.
Vegetable Broth
Makes 6-7 cups of broth
10 cups water
4 carrots, peeled & halved
4 celery stalks, each cut into 3 pieces
1 poblano or bell pepper, sliced
3 tomatoes coarsely chopped
2 large onions sliced horizontally into 3 large sets of rings
1 shallot, sliced like the onion (can be omitted, just add 2 more cloves garlic)
5 garlic cloves, smashed
10 stalks whole fresh parsley
1/2 tbsp. salt, or even better, dill salt
½ tsp. truffle oil
Combine all ingredients in a large, deep pot and simmer uncovered for 1 hour. Remove all large chunks of vegetables with tongs or a slotted spoon and strain, if desired. Taste for salt content, as sometimes I’ve doubled the salt to 1 tbsp. depending on how much liquid the vegetables give off.
Enjoy!
