Ingredients & Preparation

  1. The Basics:
    • Roast Beef: Selecting quality roast beef from your deli counter is crucial. Ask for a half-pound of their best offering to ensure your sliders are packed with flavor.
    • Buns: Hawaiian or regular slider buns serve as the perfect vehicle for these sliders. Their size and softness complement the filling wonderfully.
  2. Caramelized Onions:
    • A medium yellow onion, thinly sliced and caramelized with butter, thyme, and a pinch of salt and pepper, adds a deep, sweet flavor to the sliders. Learn how to perfectly caramelize onions here.
  3. The Cheese:
    • Provolone cheese is recommended for its ability to melt beautifully and add a creamy texture to the sliders.
  4. Au Jus:
    • A simple yet flavorful au jus made from beef broth, Worcestershire sauce, and fresh thyme, provides the perfect dipping sauce that elevates the sliders from great to unforgettable.

Assembling & Baking

  • Layering Your Sliders:
    • Start with a spread of stone ground dijon mustard on the cut side of the buns. This mustard not only adds flavor but also texture.
    • Add a generous layer of roast beef, followed by the provolone cheese, and finally, top with the caramelized onions.
    • The assembly is then topped with the other half of the buns, ready for the next step.
  • The Topping:
    • A mix of melted butter, Worcestershire sauce, toasted sesame seeds, and a dash of dijon mustard brushed over the buns adds a rich, savory flavor and ensures the sliders are golden and delicious.
  • Baking to Perfection:
    • Covered with foil and baked in a preheated oven, these sliders emerge melty, golden, and irresistible.

Serving Suggestions

French Dip Sliders can be served as a hearty meal or a delicious appetizer. Pairing them with sides like herb and garlic roasted potatoes or a fresh salad balances the meal. Don’t forget to serve the au jus on the side for dipping!
