What Kind of Onions Should I Use for French Onion Soup?
Julia Child’s original recipe calls for yellow onions, and I couldn’t agree more! Note, these are not sweet yellow onions, but plain yellow onions! I once made the mistake of using sweet onions and the flavor of the soup was definitely “off” a bit.
How Do I Make This Classic French Soup?
The soup itself cooks pretty quickly, however, the onions require a bit of time–about 30 minutes of cooking on low heat in order to caramelize.
- In a large stockpot, melt oil and butter on medium heat
- Add sliced onions; coat onions well; cover and cook for 15-20 minutes; stir onions frequently to prevent burning
- Add salt and sugar to onions; coat well; continue to cook until onions are caramelized (brown in color)
- Reduce heat to medium low; sprinkle in flour and coat onions;
- Add beef stock, wine, sage, bay leaf; allow to simmer for 30 minutes
- Taste for seasonings; add salt and pepper to your preference
What Kind of Cheese Should I Use?
Traditional, classic or authentic recipes generally use Gruyere cheese because of it’s nutty flavor and melting capabilities. Unfortunately, Gruyere is expensive and in this case, use a high-quality Swiss cheese.
