Campbell’s French Dip Sandwich Recipe: Au Jus Soaked to Perfection

This classic sandwich delivers perfectly tender beef and rich au jus for dipping. My version stays true to tradition while ensuring every bite is packed with flavor.

Slow-cooked roast beef, melted provolone, and a toasted roll come together beautifully. The au jus is the star, deep and savory for maximum dipping satisfaction.

The beef is everything here. Chuck roast gives you that fall-apart texture after slow cooking. Costco has great prices for large cuts, or grab pre-packaged at your regular supermarket. Look for good marbling—it melts into the au jus as it cooks. The provolone should be the deli kind (not pre-sliced sandwich cheese), as it melts smoother. Boar’s Head makes a solid version most stores carry.

No chuck roast? Rump roast works but needs a bit more time. Out of provolone? Swiss or mozzarella melt nicely too. For the au jus, Campbell’s beef consommé can replace the broth in a pinch—just cut back on the soy sauce. And if you’re missing Worcestershire, extra soy sauce plus a pinch of sugar gets you close. The rolls can be any crusty bread you like.

Au jus keeps for 3-4 days in the fridge—reheat gently before serving. The beef stays tender for 4 days too. Freeze both for up to 3 months (the au jus might separate but stirs back together). Assemble sandwiches fresh though—nobody wants soggy rolls.

Step-by-Step Instructions for French Dip Sandwiches

Here’s how I get that perfect au jus every time without fail.

Step 1: Sear and Season the Beef Chuck Roast

Heat the 2 tbsp olive oil in a large Dutch oven over medium-high heat. Pat the 2.5 lb beef chuck roast dry with paper towels—this ensures a good sear. Season it generously with the 1 tsp salt and 1 tsp black pepper, pressing the seasoning into the meat so it adheres well.

When the oil shimmers, add the beef and sear for 4-5 minutes per side until deeply browned. Don’t rush this step; a good sear builds flavor. You’ll know it’s ready to flip when it releases easily from the pan. Transfer the beef to a plate and set aside.

Step 2: Build the Au Jus with Aromatics

In the same pot, add the sliced 1 whole onion and cook for 3-4 minutes until softened and just starting to brown. Stir in the minced 4 cloves garlic cloves and cook for 30 seconds until fragrant—don’t let it burn.

Pour in the 3 cups beef broth, 0.25 cup soy sauce, and 2 tbsp Worcestershire sauce. Add the 1 tsp dried thyme and 1 whole bay leaf. Stir to combine, scraping up any browned bits from the bottom of the pot. These bits are packed with flavor and will deepen your au jus.

Step 3: Slow Cook the Beef to Tenderness

Return the seared beef to the pot, along with any accumulated juices. The liquid should come about halfway up the roast. Bring to a boil, then reduce the heat to low, cover, and let it simmer for 3-4 hours. You want the beef to become fork-tender—it should pull apart easily when pierced.

I check the beef occasionally and turn it once or twice during cooking to ensure even tenderness. If the liquid reduces too much, add a splash of water to keep the beef partially submerged. The house will smell incredible, and you’ll know it’s working.

Step 4: Slice the Beef and Toast the Rolls

Once the beef is tender, remove it from the pot and let it rest for 10 minutes on a cutting board. This makes it easier to slice thinly against the grain. While it rests, taste the au jus and adjust the seasoning if needed—it should be rich and savory.

Slice the 4 whole French rolls in half lengthwise and toast them lightly under the broiler or in a dry skillet. Spread the cut sides with the 1 tbsp Dijon mustard if using. The toasted rolls hold up better to the au jus soaking.

Step 5: Assemble the Sandwiches and Serve

Slice the beef thinly against the grain for maximum tenderness. Pile the beef onto the bottom halves of the toasted rolls, then top with the sliced 8 oz provolone cheese. Place under the broiler for 1-2 minutes until the cheese is melted and bubbly.

Place the top halves on the sandwiches and serve immediately with small bowls of the warm au jus for dipping. The au jus should be strained if you prefer a smoother texture, but I like the rustic bits of onion and herbs. Each bite should be juicy, flavorful, and perfectly complemented by that rich, savory dipping sauce.

Essential Equipment for Perfect Results

Dutch Oven Essentials

A heavy Dutch oven is non-negotiable for this recipe. I swear by my Le Creuset 7.25-quart—it distributes heat evenly and retains it perfectly for the 3-4 hour slow cook. The enameled cast iron also won’t react with the acidic au jus ingredients. 🔥

Sharp Slicing Knife

For paper-thin beef slices, you need a razor-sharp knife. My go-to is a Wüsthof 8-inch chef’s knife. Slice against the grain for maximum tenderness—this shortens the muscle fibers, making each bite melt in your mouth. A dull knife will tear the meat instead of cutting it cleanly.

Instant Read Thermometer

While not strictly necessary, a ThermoWorks ThermoPop gives me peace of mind. I check the beef’s internal temp after 2 hours of cooking. You’re aiming for 195-205°F for that perfect pull-apart tenderness. It’s a small investment that prevents overcooking.

Long Tongs

I use 12-inch locking tongs to turn the beef during searing and removal from the pot. They give you the reach and control needed without splattering hot liquid. Look for ones with a scalloped edge for better grip on slippery meat.

Fine Mesh Strainer

If you prefer a smooth au jus, a fine mesh strainer is essential. I pour the hot liquid through it into a bowl, pressing gently on the solids. This removes the onion and herb pieces while keeping all that rich flavor. Strain just before serving for best results.

Broiler-Safe Baking Sheet

For toasting the rolls and melting the cheese, a half-sheet pan works perfectly. I line mine with parchment for easy cleanup. The 1-2 minutes under the broiler gives the cheese that beautiful bubbly finish without burning the bread.
