  • 3 tablespoons butter, divided
  • 1 yellow onion, thinly sliced
  • 1 teaspoon water
  • 3 tablespoons stone ground mustard
  • 12 white slider buns or Hawaiian slider buns
  • 1/2 pound deli style roast beef
  • 12 slices provolone cheese
  • 1 teaspoon Worcestershire sauce
  • 2 tablespoons mayonnaise
  • 1 teaspoon Dijon-style mustard
  • 1 teaspoon sesame seeds
  • 1 tablespoon fresh parsley, chopped to garnish
  • 1 tablespoon butter
  • 1 clove garlic, minced
  • 1 cup Pacific Foods® Organic Beef Broth
  • 1 tablespoon Worcestershire sauce
  • 1/4 teaspoon dried thyme
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon sea salt


  • Step 1

    Preheat the oven to 350° Fahrenheit and grease a 9x13-inch baking sheet. Place the bottom half of the rolls in the bottom of the pan.

  • Step 2

    Caramelize onions: Add 2 tablespoons of butter to a large skillet over medium heat. Add onion and water. Cook onions, stirring occasionally, until they begin to soften and caramelize, about 20 to 25 minutes. Remove from heat.

  • Step 3

    Prepare French Dip sandwiches: Spread an even layer of stone ground mustard onto rolls. Top with a layer of roast beef and a layer of provolone. Top with caramelized onions, then cover with the tops of the rolls.

  • Step 4

    Melt 1 tablespoon of butter and mix with Worcestershire, mayonnaise, Dijon mustard, and sesame seeds. Spread over the buns. Cover with foil and bake until golden and cooked through, about 20-30 minutes. Remove from the oven and sprinkle with fresh parsley.

  • Step 5

    Prepare the Au Jus Sauce: Add remaining butter to a small saucepan over medium heat. Stir in garlic and cook until fragrant, about 1-2 minutes. Add Beef Broth, Worcestershire sauce, thyme, sea salt, and pepper. Simmer for 10 minutes until reduced slightly.

  • Step 6

    Serve squares of French Dip Sandwiches with Au Jus on the side for dipping.
