📝 About This Recipe

Born in the bustling kitchens of early 20th-century Los Angeles, the French Dip is a West Coast icon defined by its simplicity and soul-warming depth. This recipe features paper-thin ribbons of slow-roasted beef tucked into a crusty baguette that has been perfectly toasted to withstand a deep dive into a concentrated, savory beef consommé. It is the ultimate comfort sandwich, balancing the crunch of the bread with the melt-in-your-mouth tenderness of premium prime rib or chuck roast.

🥗 Ingredients

The Roast Beef

  • 3 pounds Beef Chuck Roast or Prime Rib (well-marbled)
  • 1 tablespoon Kosher Salt
  • 2 teaspoons Black Pepper (freshly cracked)
  • 2 tablespoons Vegetable Oil (for searing)

The Au Jus (Dipping Sauce)

  • 4 cups Beef Stock (low sodium, high quality)
  • 1 Yellow Onion (halved and sliced)
  • 4 cloves Garlic (smashed)
  • 3 sprigs Fresh Thyme
  • 1 tablespoon Worcestershire Sauce
  • 1/2 cup Red Wine (dry variety like Cabernet Sauvignon)

The Sandwich Assembly

  • 4-6 pieces French Baguettes or Hoagie Rolls (crusty on the outside, soft inside)
  • 6-8 slices Provolone or Gruyère Cheese (optional but recommended)
  • 3 tablespoons Unsalted Butter (softened)
  • 1/4 cup Creamy Horseradish (for serving)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 300°F (150°C). Pat the beef roast completely dry with paper towels and season generously on all sides with kosher salt and cracked black pepper.

  2. 2

    In a large Dutch oven, heat the vegetable oil over medium-high heat. Sear the beef until a deep, dark brown crust forms on all sides, about 4-5 minutes per side.

  3. 3

    Remove the beef temporarily. Add the sliced onions to the pot and sauté for 5 minutes until softened and slightly caramelized.

  4. 4

    Deglaze the pot by pouring in the red wine, scraping up all the flavorful brown bits (fond) from the bottom with a wooden spoon.

  5. 5

    Add the garlic, thyme sprigs, beef stock, and Worcestershire sauce. Return the beef to the pot; the liquid should come about halfway up the sides of the meat.

  6. 6

    Cover with a tight-fitting lid and transfer to the oven. Braise for 3 to 3.5 hours, or until the beef is tender enough to slice but not quite falling apart.

  7. 7

    Remove the beef from the liquid and let it rest on a cutting board for at least 20 minutes. This is crucial for keeping the juices inside the meat.

  8. 8

    While the meat rests, strain the braising liquid through a fine-mesh sieve into a saucepan. Skim off the excess fat from the surface and simmer the liquid over medium heat to concentrate the flavors for 10 minutes.

  9. 9

    Using a very sharp knife (or a meat slicer if you have one), slice the beef against the grain into the thinnest ribbons possible.

  10. 10

    Split your baguettes lengthwise. Spread softened butter on the cut sides and toast under a broiler for 1-2 minutes until golden brown.

  11. 11

    Optional: Place slices of Provolone on the top half of the toasted bread and return to the broiler for 30 seconds until melted and bubbly.

  12. 12

    Dip the sliced beef briefly into the hot au jus to re-moisten it, then pile it high onto the bottom half of the toasted rolls.

  13. 13

    Close the sandwiches and cut them in half on a bias. Serve immediately with individual small bowls of the hot au jus for dipping.

💡 Chef's Tips

For the thinnest slices, chill the cooked beef for an hour before slicing, then reheat the slices in the warm au jus. Always toast the bread; a soft roll will disintegrate the moment it touches the jus. If the au jus is too salty after reducing, add a splash of water or a pinch of sugar to balance it. Use a high-quality store-bought beef bone broth if you don't have time to make a scratch stock for a richer mouthfeel. Don't skip the rest period for the meat, or the sandwich will be dry despite the dipping sauce.

🍽️ Serving Suggestions

Serve with a side of extra-crispy sea salt french fries or potato chips. A side of spicy pickled peppers or giardiniera cuts through the richness of the beef. Pair with a cold West Coast IPA or a glass of robust Napa Valley Cabernet Sauvignon. Offer a small ramekin of extra-strong horseradish cream for those who like a nasal-clearing kick. A simple arugula salad with a lemon vinaigrette provides a refreshing contrast to the savory sandwich.
