Why This Works

The slow caramelization of onions brings out their natural sweetness. This layered flavor is the key to a delicious soup.

A good quality broth enhances the soup's richness. Topped with melted cheese and toasted bread, it creates a delightful contrast.

💡 Professional Tip

For deeper flavor, use a blend of beef and chicken broth. Don't rush the caramelization; patience is key to developing sweetness.

Frequently Asked Questions

Recipe Troubleshooting Guide

Too Salty

Problem: The soup may become overly salty if the broth is too seasoned.

Solution: Add a potato to absorb excess salt while simmering, then remove it before serving.

Lacks Depth

Problem: If the flavor is flat, it may need more seasoning.

Solution: Add a splash more vinegar or a teaspoon of sugar to balance the flavors.

Not Creamy

Problem: The soup may not be as creamy as desired.

Prevention: Stir in a tablespoon of cream before serving for added richness.

Undercooked Onions

Problem: If onions are still crunchy, they haven't caramelized properly.

Recovery: Continue cooking on low heat until they soften and turn golden brown.

Burnt Flavor

Problem: If the onions burn, they can impart a bitter taste.

Prevention: Lower the heat and stir frequently to prevent burning during caramelization.

Flavor Issues

Too Sweet: If too sweet, add a dash of vinegar to cut the sweetness.

Too Salty: If too salty, add water or unsalted broth to dilute.

Bland: If bland, boost with more seasoning and herbs.
