  • 2 white onions
  • 2 tablespoons butter
  • 1 quart water
  • 1 teaspoon powdered chicken bouillon
  • Salt
  • Black pepper
  • Mexican oregano
  • 2 ounces croutons


  • Roughly chop the onions into short strips.
  • Heat 2 tablespoons of butter in your pan.
  • Add the chopped onions to the pan with a pinch of black pepper.
  • Cook the onions until they are translucent, about 8 to 10 minutes.
  • Add 1 quart of water to the pan.
  • Add the teaspoon of powdered chicken bouillon.
  • Simmer for 20 minutes.
  • Adjust the salt.
  • Serve in individual bowls and garnish with a few croutons and a pinch of Mexican oregano.


  • You can substitute yellow onions for the white onion. Simmer for an extra 10 minutes.
  • You can substitute regular oregano for Mexican oregano.
Preparation Notes
  • You may not have to add extra salt because powdered bouillons tend to be salty. Taste the soup just before serving and adjust the salt if necessary.
  • The flavors blend nicely if you let the soup sit for 30 minutes. Heat to desired temperature before serving.
  • It keeps well in the refrigerator for 3 days although we doubt you will have leftovers.
