Restaurant-Style French Onion Soup Is Easier Than You Think

Recipe By: Jenny
“Classic French onion soup, similar to one you can get in a restaurant. Made with wine and sherry to bring out the beef flavor of the broth. Two different cheeses top it off to give it that bubbly, browned, and stretchy topping.”

Ingredients

  • 1/2 cup butter
  • 8 onions, sliced
  • 2 cloves garlic, crushed
  • 1/2 teaspoon salt, or to taste
  • 1/2 teaspoon ground black pepper, or to taste
  • 1 teaspoon dried thyme
  • 1 cup red wine
  • 1 tablespoon sherry
  • 2 tablespoons all-purpose flour
  • 2 quarts beef broth
  • 1 French baguette, cut into 1/2-inch thick slices
  • olive oil, or as needed
  • 6 slices Swiss cheese
  • 6 slices provolone cheese

Directions

  1. Melt butter in a large soup pot over medium heat. Cook and stir onions, garlic, salt, black pepper, and thyme until onions are soft and brown, about 30 minutes. Pour in red wine and sherry; bring to a boil. Reduce heat to low and simmer until you can no longer smell alcohol cooking off, about 15 more minutes.
  2. Sprinkle onion mixture with flour and stir until coated; cook for 10 minutes. Pour in broth, stir to blend in flour, and simmer until slightly thickened, about 20 minutes.
  3. Preheat oven to 350 degrees F (175 degrees C) while soup is simmering. Arrange bread slices on a baking sheet and drizzle with olive oil.
  4. Toast the baguette slices in the preheated oven until golden brown, 12 to 14 minutes, turning the bread over halfway through cooking. Remove toast and set aside.
  5. Set an oven rack about 8 inches from the heat source and turn on the oven’s broiler.
  6. Ladle soup into 6 oven-proof crocks, filling them about 3/4 full. Place 1 or 2 bread slices into the bowls and top each with a slice of Swiss cheese and a slice of provolone. Carefully place filled crocks onto a sturdy baking sheet.
  7. Broil soup until the cheese is browned and bubbling, 3 to 4 minutes.
