Ingredients for French Dip Sandwhich

Tender roast beef, crusty bread, and a rich au jus make this sandwich unforgettable at home.

Ingredient Amount Notes
Beef Chuck Roast 🥩 3 lb Trimmed of excess fat
Kosher Salt 🧂 1 tbsp Plus more to taste
Black Pepper 🌶️ 1 tsp Freshly ground preferred
Dried Thyme 🍃 1 tsp Or fresh thyme leaves
Dried Rosemary 🌿 1 tsp Crushed between fingers
Bay Leaves 🍃 2 whole For au jus depth
Garlic Cloves 🧄 6 cloves Smashed, peeled
Beef Broth 💧 4 cups Low-sodium preferred
Soy Sauce 🥢 ¼ cup For umami boost
Worcestershire Sauce 🍶 2 tbsp Essential for au jus
Baguette 🥖 1 whole Crusty French loaf
Unsalted Butter 🧈 4 tbsp For toasting bread
Dijon Mustard 🟡 ¼ cup For sandwich spread
Provolone Cheese 🧀 8 oz Sliced, optional

The beef is everything here. Chuck roast is ideal—well-marbled, affordable, and falls apart after slow cooking. Look for a 3-pound piece at Whole Foods or your butcher (they’ll trim it for you). The dried herbs should be fresh-packed—old spices lose their punch. Costco has reliable beef broth in bulk, but any good-quality low-sodium works too.

No chuck roast? Bottom round or rump roast are solid backups—leaner, but still flavorful. Swap soy sauce for tamari if gluten-free is needed. Fresh herbs can replace dried at triple the amount. The baguette must be crusty—skip the soft sandwich bread. Provolone can be swapped for Swiss or Gruyère if you prefer a nuttier melt.

Au jus keeps 5 days refrigerated or 3 months frozen. Slice the beef against the grain before serving. Store leftover sandwiches wrapped tightly—they’re great cold the next day (reheat the jus separately).

Step-by-Step Instructions for French Dip Sandwich

Master the slow-cooked beef and rich au jus with these tested techniques.

Step 1: Season and Sear the Beef Chuck Roast

Pat the 3 lb Beef Chuck Roast dry with paper towels, then rub it generously with the 1 tbsp Kosher Salt, 1 tsp Black Pepper, 1 tsp Dried Thyme, and 1 tsp Dried Rosemary. Press the seasoning into the meat so it adheres well during cooking.

Heat a large Dutch oven over medium-high heat until hot. Sear the roast on all sides until deeply browned—about 4-5 minutes per side. This creates a flavorful crust that will infuse the au jus with rich, meaty depth. Don’t rush this step; a good sear is essential.

Step 2: Build the Au Jus and Slow-Cook the Beef

Reduce heat to medium and add the 6 cloves Garlic Cloves, 2 whole Bay Leaves, 4 cups Beef Broth, 0.25 cup Soy Sauce, and 2 tbsp Worcestershire Sauce to the Dutch oven. The liquid should come about halfway up the roast.

Bring to a gentle simmer, then cover and reduce heat to low. Cook for 3-4 hours, turning the roast occasionally, until the beef is fork-tender and shreds easily. The au jus should reduce slightly and develop a deep, savory flavor from the beef and aromatics.

Step 3: Shred the Beef and Strain the Au Jus

Remove the roast from the Dutch oven and place it on a cutting board. Use two forks to shred the beef into thin, tender strands. Discard the bay leaves and any large pieces of garlic, then strain the au jus through a fine-mesh sieve into a separate bowl to remove any solids.

Return the shredded beef to the Dutch oven and pour enough strained au jus back over it to keep the meat moist—about 1-2 cups. This ensures the beef stays juicy while you prepare the sandwiches.

Step 4: Toast the Baguette and Assemble the Sandwiches

Slice the 1 whole Baguette into 4 equal portions, then split each piece horizontally. Spread the cut sides with the 4 tbsp Unsalted Butter and toast in a skillet over medium heat until golden brown—about 2-3 minutes per side.

Spread the toasted bread with the 0.25 cup Dijon Mustard, then pile the shredded beef on the bottom half of each roll. Top with the 8 oz Provolone Cheese if using, and place the sandwiches under a broiler for 1-2 minutes to melt the cheese. Serve immediately with small bowls of the warm au jus for dipping.

Pro Tips For Making French Dip Sandwhich

  • Sear the Chuck: I learned this the hard way—skip the sear and your au jus will taste flat. Get that chuck roast good and brown in a screaming hot pan before braising; about 3-4 minutes per side.
  • Toast the Rolls: Sounds obvious, but I was lazy about it until I tried both ways. A quick 30 seconds in the oven with a little butter makes the sandwich hold up to that juicy meat and broth.
  • Skip the Overcrowding: When browning the beef, resist the urge to cram it all in one pan. Work in batches—it’ll brown instead of steam, and your au jus will have real depth.
  • Strain and Skim: After braising, strain the liquid and skim off the fat—your future self will thank you. A clean, rich au jus is what makes a French dip unforgettable, not greasy.

Storing and Reheating This Recipe

Refrigerator Storage

Let the beef and au jus cool to room temperature within 2 hours of cooking. Store them separately in airtight containers—I use glass containers with snap-tight lids. They’ll keep in the fridge for up to 4 days. ❄️

Freezer Storage

For longer storage, freeze the beef and au jus in separate containers. I recommend using quart-sized freezer bags for the au jus and vacuum-sealed bags for the beef. Both will stay fresh for up to 3 months without losing quality.

Reheating the Beef

To reheat the beef, place it in a saucepan with a splash of au jus or beef broth. Warm over medium-low heat for 5-7 minutes, stirring occasionally, until heated through. This prevents the meat from drying out. 🔥

Reheating the Au Jus

Pour the au jus into a small saucepan and heat over medium heat for 3-5 minutes, stirring occasionally. If it has thickened in storage, add a little water or beef broth to thin it out to your desired consistency.

Assembling Leftovers

To assemble leftover sandwiches, toast the baguette as you would fresh bread. Reheat the beef and au jus separately, then assemble the sandwiches just before serving to maintain the bread’s crispness.

Frequently Asked Questions

1

Can I use a different cut of beef?

Yes! Bottom round or rump roast work well, though they’re leaner. Avoid very fatty cuts like brisket, as they won’t shred as cleanly.

2

How do I keep the bread from getting soggy?

Toast the baguette just before serving and keep the au jus in separate bowls. Assemble sandwiches only when ready to eat.

3

Can I make this in a slow cooker?

Sear the beef first, then transfer to a slow cooker with all liquids. Cook on low for 8 hours or high for 5-6 hours.

4

What’s the best cheese for this?

Provolone is classic, but Swiss or Gruyère add great flavor. Skip pre-shredded—it doesn’t melt as smoothly.
