This is a dried version of the basics, which, with the included salt, can be used in place of vegetable bouillon cubes. Found this on the German Rezepte-Wiki site when I was looking for a vegetable bouillon substitute. If you are not that ambitious to do this, “Vegeta” might be a good alternative for you.

Ingredients:

Makes about 1 cup of dried powder.

• 140 g    Onions
•   60 g    Kosher Salt
•   85 g    Carrots
•   25 g    Leek
•   65 g    Celeriac
•   10 g    Parsley
• 150 g    Tomatoes

Directions:

Clean all vegetables and mince finely.
Add the salt and mix everything thoroughly.
Spread out evenly on Parchment covered cookie sheet(s).
Dry in convection oven at 170ºF for 7 – 8 hours. Or use a dehydrator.

Pulverize dried vegetables in blender and transfer to a Ball jar with lid.
Store in cool, dry place.

Use as needed to improve soups or sauces.
