How to use Vegetable Bouillon Cubes

Using a vegetable bouillon cube or powder is really very easy. Both are used in the same way in order to give flavors to savory dishes such as soups, pasta, risotto, broth, ramen.

Generally speaking, you should add one vegetable bouillon cube in a pot with 4 cups of boiling water. On the other hand, use 1 teaspoon of bouillon powder per 1 cup of water. It is best not to add the salt too. However according to the recipe, you can also add it later, for example by sprinkling it on baked potatoes.

Can you make a Vegetable Bouillon Powder with this recipe?

Absolutely! If you want to make the vegetable bouillon powder, just let the mixture dry in the oven at150°F/65°C for at least a 4-5 hours, or until it will have lost all its moisture. The timing depends on the thickness of the layer and humidity, so it's best to layer the puree very thinly.

You can also make the bouillon powder in the dehydrator. Set a temperature to 150°F/65°C and let it dry for up to 9-10 hours, checking halfway through cooking. Making very thin layers always helps speed up the process.

Whether you let the vegetable bouillon dehydrate in the oven or dehydrator, at the end you always have to blend the small flakes obtained in a food processor. Sieve and repeat until very thin. Finally, store the bouillon powder in a jar for up to 6 months, placed in a cool, dark place.


Depending on the season, you can use your favorite vegetables. The basic ones are usually onions, celery, leeks and carrots but you can also add other vegetables, such as pumpkin, zucchini, cauliflower, potatoes, chard and tomatoes.

The amount of salt should always be 25 grams for every 100 grams of raw vegetables.

If you like, you can also add spices, such as ground black pepper, curry or turmeric.
