Key ingredients and why they matter

Yellow onions

Yellow onions are the heart of this recipe. They become sweet and rich as they cook down. Their natural sugars brown slowly, giving the soup its signature color and flavor.

Butter and olive oil

Butter adds richness, while olive oil helps keep the butter from browning too quickly. Together, they make the onions glossy and flavorful.

Beef broth

Traditional versions often use beef broth because it adds savory depth. A good broth gives the soup body without needing expensive ingredients.

Thyme and bay leaf

These herbs add a gentle earthy flavor. They should support the onions, not cover them up.

Bread and cheese

The toasted bread soaks up the broth, while melted cheese turns the bowl into a full meal. Gruyere is classic, but Swiss or provolone also work well.

A splash of vinegar

A small amount of sherry vinegar or balsamic vinegar wakes up the soup at the end. It balances the sweetness of the onions and keeps the flavor from tasting flat.

Step-by-step instructions

Step 1

Slice the onions thinly and evenly. Heat butter and olive oil in a large heavy pot over medium heat.

Step 2

Add the onions, salt, and pepper. Cook for 35 to 45 minutes, stirring often, until the onions turn deep golden brown.

Step 3

Stir in the garlic, thyme, bay leaf, and flour. Cook for 1 to 2 minutes so the flour loses its raw taste.

Step 4

Pour in the wine, scraping the browned bits from the bottom of the pot. Add broth and Worcestershire sauce, then simmer for 20 minutes.

Step 5

Stir in the vinegar. Ladle into oven-safe bowls, top with toasted bread and cheese, then broil until melted and bubbly. Serve and enjoy.

Safety tip Use oven-safe bowls if broiling the cheese. If you do not have them, melt cheese on toast separately and place it on top of the soup before serving.

Chef’s secrets for better flavor

The best version of this soup comes from careful heat, good seasoning, and a strong finish.

• Cook the onions slowly High heat can burn onions before they caramelize. Medium or medium-low heat gives the best color and sweetness.

  
  

• Season in layers Add salt early to help draw moisture from the onions. Taste again after the broth simmers.

  
  

• Use homemade stock when possible Homemade beef or vegetable stock can make the soup taste fuller. Store-bought broth works too, especially low sodium.

  
  

• Scrape the pot The browned bits on the bottom hold a lot of flavor. Wine or broth helps lift them into the soup.

  
  

• Finish with acid A teaspoon of vinegar at the end brightens the whole pot.

  
  

• Add fresh herbs late Fresh thyme or parsley tastes best when added right before serving.

  
  

Broiling the bread and cheese turns the soup into a hearty, satisfying meal.

Chef’s variations

Dietary substitutions

Gluten-free

Use gluten-free flour or cornstarch to lightly thicken the soup. Serve with gluten-free bread or skip the bread and add extra cheese on top.

Dairy-free

Use olive oil instead of butter. Choose a dairy-free cheese or serve the soup with toasted dairy-free bread and fresh herbs.

Vegetarian

Use vegetable broth instead of beef broth. Add a splash of soy-free tamari or extra mushrooms to build savory flavor, if desired.

Vegan

Use olive oil, vegetable broth, dairy-free cheese, and vegan bread. Skip Worcestershire sauce unless the label says vegan.

Flavor twists

Spicy version

Add a pinch of red pepper flakes while the onions cook. A small amount goes a long way.

Smoky version

Add smoked paprika or use a smoked cheese topping.

Southwest version

Use a little cumin and chili powder, then finish with cilantro and pepper jack cheese.

Mediterranean version

Add rosemary, oregano, and a few roasted garlic cloves. Finish with parsley and a drizzle of olive oil.

Make-ahead tips

Cook the soup base up to 3 days ahead. Store it without bread or cheese. When ready to serve, reheat the soup, toast the bread, add cheese, and broil.

Meal prep notes

The soup base lasts well in the refrigerator for 4 days and freezes for up to 3 months. For best texture, freeze only the broth and onion mixture. Add bread and cheese after reheating.

Storage and reheating

Refrigerator

Store cooled soup in an airtight container for up to 4 days. Keep bread and cheese separate.

Freezer

Freeze the soup base for up to 3 months. Leave a little space in the container because liquid expands as it freezes.

Reheating

Stovetop

Warm over medium heat, stirring now and then, until hot. Add a splash of broth or water if the soup has thickened.
