1-1/2 – 1-3/4 cup white sauce – see recipe below
2 cups thinly sliced sweet yellow onions
2 tablespoons butter
1 x 15 ounce can chicken broth
1/4 teaspoon salt
1/4 teaspoon freshly-ground pepper
2 chicken bouillon cubes
1/4 cup diced Velveeta (compressed in measuring cup)
shredded Cheddar cheese (for garnish)
For white sauce :
3 tablespoons butter
3 tablespoons flour
1/4 teaspoon salt
1-1/2 cups whole milk
Prepare white sauce :
In a quart saucepan melt butter and add flour, cook on medium heat until the flour turns thick and comes away from the side of the saucepan. Pour milk in flour a little at a time and stir constantly, add salt. Mixture should thicken and become like thick pudding. Remember to stir constantly, taking care not to let mixture lump. Remove from heat and set aside until ready to use for the soup.
For soup :
Place 3 tablespoons butter and sliced onions In a 2-quart saucepan. Cook over low to medium heat stirring frequently until soft and clear but not brown. Add chicken broth, chicken bouillon cubes, salt and pepper. Stir until completely heated through.
Add white sauce and Velveeta cheese. White sauce will be thick because it has been removed from the heat.
Simmer on medium low heat until the cheese is melted and all are blended, stirring constantly.
Turn temperature to warm and let cook for additional 30 to 45 minutes.
