This is my all-time favorite soup. Unlike many chain restaurants' (and I have tried many chain restaurants' French Onion Soup), this soup base is a delicate clear liquid. It's heavenly.
You will need:
2 white or yellow onions
4 stems fresh thyme
2 bay leaves
1/4 c. olive oil
1 box of chicken broth (or 4 c. homemade stock)
1/2 cup dry white wine **Note: you can also use beef broth and beer in place of the chicken broth and wine.** It’s a slightly heartier taste.
Salt and freshly ground black pepper to taste
4 slices of French bread (large baguette or sourdough)
8 slices of baby Swiss cheese (or Gruyere)
Large heavy skillet or stock pot
4 Oven-proof bowls
