Tips:

  • Use high-quality ingredients: Fresh, flavorful ingredients will make a big difference in the taste of your soup. Look for sweet onions, a good quality Swiss cheese, and fresh basil.
  • Caramelize the onions slowly and patiently: This is the key to developing their rich, sweet flavor. Don't rush the process.
  • Use a good quality beef broth: This will give your soup a rich, beefy flavor. If you don't have beef broth, you can use chicken broth or vegetable broth instead.
  • Don't overcrowd the pot: When you're adding the onions to the pot, make sure you don't overcrowd it. Otherwise, they won't caramelize properly.
  • Season to taste: Once your soup is finished, taste it and adjust the seasonings as needed. You may want to add more salt, pepper, or herbs.
