The Best French Onion Soup

This French Onion Soup recipe combines caramelized yellow onions with sherry and red wine for depth, enhanced by tomato paste, garlic purée, and beef base in a rich chicken stock. The soup is topped with toasted baguette slices and melted provolone and gruyere cheeses, yielding a hearty and aromatic dish. The long caramelization process creates sweet, deeply browned onions adding body and flavor. A bouquet garni flavors the broth, finished with fresh thyme garnish.

Description

The Best French Onion Soup centers around slowly caramelized yellow onions cooked in butter and canola oil until deeply browned and sweet, a process taking about an hour. Deglazing the pot with sherry and red wine enriches the base, followed by stirring in tomato paste and garlic purée for savory complexity. The soup is then simmered with chicken stock and beef base, with herbs tied into a bouquet garni contributing subtle flavor nuances.

The soup develops a rich, layered flavor from the caramelized onions and wine reduction. It is finished by ladling into bowls topped with baguette slices and slices of provolone and shredded gruyere cheese, then broiled until the cheese melts and bubbles, creating a creamy, golden crust.

This soup can be served as a starter or a satisfying main course with hearty bread or salad. It is best enjoyed hot to benefit from the melted cheese topping and the aromatic broth. The recipe allows refrigeration for up to 4 days and freezing for up to 3 months, making it a convenient make-ahead option.

Instructions

  1. In a large stock pot or Dutch oven, melt the butter and canola oil together over high heat and add the onions Sauté, stirring occasionally until they start to caramelize, about 15 minutes.

  4. Skim the butter fat/foamy liquid from the top, and discard. Taste for seasoning and add salt or pepper as desired. Remove the bouquet garni. 
  5. Ladle the soup into oven-safe bowls and top with 2-3 slices of the baguette, then top with a slice of provolone cheese and grated gruyere if desired. Place the bowls on a baking sheet and broil for 3-4 minutes or until the cheese is melted. Garnish with fresh thyme leaves and serve. 

Notes

  • The soup can be refrigerated up to 4 days or frozen up to 3 months for later use.
