Ingredients You’ll Need

For the French Onion Mix

  • 2 large onions, thinly sliced
  • 2 tablespoons of butter
  • 1 tablespoon of olive oil
  • 1 teaspoon of sugar
  • 1 teaspoon of balsamic vinegar
  • 1 teaspoon of fresh thyme leaves
  • Salt and pepper to taste

For the French Dip Sandwiches

  • 1 pound of thinly sliced roast beef
  • 4 French baguettes
  • 8 slices of Swiss cheese
  • 4 tablespoons of mayonnaise
  • 4 tablespoons of Dijon mustard
  • 4 cups of beef broth
  • 1 clove of garlic, minced
  • 2 tablespoons of olive oil
  • Salt and pepper to taste

The Preparation

Creating the French Onion Mix

  1. Sauté the Onions: In a large skillet, melt the butter and olive oil over medium-low heat. Add the thinly sliced onions and cook them slowly until they caramelize, which takes about 30-40 minutes.
  2. Add Flavor: Stir in the sugar, balsamic vinegar, fresh thyme leaves, salt, and pepper. Continue to cook for an additional 5 minutes until everything is well combined and fragrant.

Assembling the French Dip Sandwiches

  1. Preheat Your Oven: Set it to 350°F (175°C) to toast the baguettes.
  2. Prepare the Bread: Cut the French baguettes in half and place them on a baking sheet. Toast them in the oven for about 5 minutes until they turn golden brown.
  3. Layer the Goodness: Spread mayonnaise and Dijon mustard on one side of each baguette. On the other side, place a slice of Swiss cheese.
  4. Add the Roast Beef: Pile on the thinly sliced roast beef, creating a generous layer.
  5. Final Touch: Top the beef with a spoonful of the French onion mix.

Bringing It All Together

  1. Dip and Sizzle: In a separate pan, heat the beef broth and minced garlic until it’s simmering hot. Pour this fragrant broth into small dipping bowls.
  2. Serve Hot: Plate your French Onion French Dip Sandwiches alongside the bowls of beef broth, and you’re ready to serve.
