Print Recipe

French Dip Sliders are warm baked mini sandwiches layered with roast beef, provolone, buttery onions, and a savory au jus dip.

Ingredients

Scale
  • 3 tablespoons unsalted butter
  • 1 medium onion, thinly sliced
  • 2 teaspoons fresh thyme, minced
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 12 sweet rolls
  • 10 slices provolone cheese
  • 14 ounces sliced deli roast beef
  • 1/2 cup unsalted butter, melted
  • 1 1/2 tablespoons dried onion soup mix
  • 1 packet au jus gravy mix
  • 3 cups water
  • Fresh chopped parsley, optional garnish

Instructions

  1. Warm 3 tablespoons of butter in a large skillet over medium heat. Add the sliced onion and stir until coated.
  2. Cook the onion for 12 to 15 minutes, stirring now and then, until tender and lightly browned.
  3. Add the thyme, salt, and pepper, then remove the skillet from the heat.
  4. Heat the oven to 350°F. Slice the connected rolls in half horizontally and place the bottom half in an 11×7 baking dish.
  5. Arrange half of the provolone over the rolls, then layer on the roast beef.
  6. Spoon the cooked onions over the beef, add the remaining provolone, and place the roll tops back on.
  7. Mix the melted butter with the dried onion soup mix, then brush it evenly over the rolls.
  8. Cover the baking dish loosely with foil, keeping it from touching the tops, and bake for 25 minutes.
  9. Remove the foil and bake for 5 more minutes, until the rolls are lightly golden.
  10. Prepare the au jus gravy mix with 3 cups water according to the package directions.
  11. Sprinkle with parsley if desired and serve warm with au jus for dipping.

Notes

  • Dried herbs may replace fresh herbs; use half as much.
  • Any slider buns can work, though sweet rolls add a soft, slightly sweet bite.
  • Provolone or mozzarella both melt nicely in this recipe.
  • The au jus can be skipped, but it gives the sliders their classic dipping flavor.
  • Cool completely before freezing, then wrap well for later.
