Ingredients

  • 6 large onions, chopped
  • 6 cups bouillon liquid
  • 1.5 teaspoons Worcestershire sauce
  • 3 tablespoons butter
  • salt and pepper to taste
  • French bread slices
  • Mozzarella cheese

Instructions

  1. Brown the chopped onions in butter until tender.
  2. Add the bouillon liquid, Worcestershire sauce, salt, and pepper.
  3. Cook until the onions are tender and flavors meld.
  4. Place a slice of French bread in each bowl.
  5. Pour the hot soup over the bread slices.
  6. Sprinkle with mozzarella cheese and optionally heat until cheese melts.

Tips & Substitutions

For a richer flavor, consider adding a splash of white wine while cooking the onions. If you're out of Worcestershire sauce, soy sauce or balsamic vinegar can work as substitutes. To enhance the soup's texture, you can blend a portion of the soup before serving. For a vegetarian version, use vegetable bouillon instead of chicken.

Serving Suggestions

Serve the soup piping hot, garnished with additional mozzarella cheese or fresh herbs like thyme or parsley. It pairs beautifully with French bread or a side salad for a complete meal. For a twist, try serving alongside Cucumber Cream Cheese Spread Or Cucumber Roll-Ups as a refreshing appetizer.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm on the stovetop over low heat, stirring occasionally, until heated through. You can add a little water or broth if the soup thickens too much. Avoid microwaving as it may change the texture of the cheese.

Frequently Asked Questions

Can I use pre-sliced onions for this recipe?

While pre-sliced onions can save time, they often lack the freshness and flavor of freshly chopped onions. If you choose to use them, ensure they're of good quality and adjust cooking time, as they may cook faster than whole onions.

How can I make this soup spicier?

To add some heat, consider incorporating red pepper flakes or a dash of hot sauce while cooking the onions. You can also serve the soup with sliced jalapeños or a sprinkle of cayenne pepper on top before serving for an extra kick.

Can I freeze leftover onion soup?

Yes, you can freeze the soup, but it's best to do so without the cheese and bread. Allow it to cool completely, then transfer to freezer-safe containers. When ready to eat, thaw in the refrigerator overnight and reheat on the stovetop, adding fresh cheese before serving.
