Description

Cozy up with a warm, cheesy bowl of classic French Onion Soup. This version is made in the traditional way by cooking down and caramelizing fresh onions until they are a deep golden brown, then deglazing the pan with wine before letting all those flavors simmer together. Top off each bowl of soup with a thick piece of French bread and some melty cheese for a deeply flavorful, savory meal you'll crave all winter long.


Ingredients

  • ¼ cup butter
  • 4 medium onion, thinly sliced
  • 1/4 cup dry sherry or white wine 
  • 1 tablespoon all-purpose flour
  • 6 cups beef broth
  • 1 teaspoon fresh thyme, finely chopped
  • 1/2 teaspoon salt (or to taste)
  • 1/2 teaspoon ground black pepper
  • 6 slices French bread, about 1/2 inch thick
  • 1 1/2 cups Gruyère cheese, grated

Instructions

  1. Melt butter in a large pot or 4 quart Dutch oven over medium-high heat and melt until it starts to bubble, about 1 minute. Add onion and sauté until tender and golden brown, about 12-15 minutes.
  2. Add wine and stir well to deglaze the pot. Stir in flour and mix well until evenly combined and thickened, about 1 minute.
  3. Add beef broth and thyme. Mix well and bring the mixture to a simmer. Let it simmer over medium heat for 10 minutes. Season with salt and pepper to taste.
  4. Preheat broiler on Hi for 5 minutes. Ladle soup into individual oven-safe serving bowls and place the serving bowls on a large baking sheet (you may have to do this in batches).
  5. On each bowl, add a slice of bread on top and sprinkle with 1/4 cup of cheese.
  6. Transfer the baking sheet into the oven and broil until the melted cheese turns golden brown, about 1 minute.
  7. Garnish with some chopped thyme and serve warm.

Notes

How to store: Store leftover French onion soup in an airtight container or jar in the fridge for 3-4 days. Store the bread and cheese separately to keep them from becoming soggy.

How to reheat: Heat up some of this easy onion soup in a small saucepan over medium-low heat before topping it with freshly toasted bread and cheese.

How to freeze: Freeze chilled leftover soup in a freezer safe container for 2-3 months. Thaw overnight in the fridge before reheating.
