Things You'll Need:
- Onion (sweet)
- Vegetable broth cubes
- water
- Bread (white loaf)
-
Step 1
Take 1 large onion, preferably a Vidalia or Spanish onion (which are sweet) and slice it into long thin strips.
-
Step 2
In a medium sauce pan on medium-low heat, add a tablespoon of olive oil or vegetable oil. Add the onion and stir frequently for 5-10 minutes, until they caramelize (they will become lightly golden brown).
-
Step 3
In another large pot, boil about 1/2 a gallon of water. Once the water comes to a boil and the onions caramelize, add them to the water. Reduce heat to medium.
-
Step 4
Add 3-4 vegetable broth cubes (more if you want stronger flavor). Add seasoning to taste (black pepper) - but you don't need much/any salt since there's plenty in the broth cubes.
-
Step 5
Lightly toast some slices of white bread. Pour the soup into bowls and add a slice of bread into each bowl. Top with gruyere cheese -- mozzarella will also work well. Place bowls into toaster or oven (bake at 350) for a few minutes to melt and brown the cheese.
