How to Make French Dip Sandwich with Au Jus and Grilled Gruyère Recipe

Step 1: Prepare the Steak

Start by seasoning your skirt or flank steak generously with kosher salt and freshly cracked black pepper. Heat a cast-iron skillet over high heat until it’s screaming hot—this is key to getting that beautiful crust that locks in juices. Sear the steak about 3 minutes per side for a perfect medium-rare finish, or until the internal temperature hits 135°F on your thermometer. Let it rest for 5 minutes to redistribute the juices, then slice as thinly as possible against the grain. Thin slices mean every bite is tender and juicy.

Step 2: Make the Au Jus

While the steak rests, let’s build that unbeatable au jus. In a medium saucepan over medium heat, whisk together beef stock, dried thyme, kosher salt, sherry wine, Worcestershire sauce, garlic powder, and onion powder until smooth. Let this simmer, stirring occasionally, for about 5 minutes so the flavors meld into a rich, aromatic broth perfect for dipping. This sauce is the heart of the French dip experience.

Step 3: Butter and Season the Rolls

Take your rolls and spread the softened butter inside evenly. Sprinkle each one with garlic powder to infuse them with that irresistible garlic punch. Then place the rolls open-faced on a rimmed baking sheet, ready for their next transformation under the broiler. This step adds buttery softness and a savory kick to every bite.

Step 4: Assemble and Broil

Turn your broiler to HIGH. Quickly give the tender steak strips a dip in the warm au jus for that extra burst of flavor and moisture. Layer the juicy meat evenly on one side of each buttered roll, then generously sprinkle about half a cup of grated Gruyère over the top. Slide the baking sheet under the broiler just until the cheese begins to melt and bubble, about 2 minutes. Keep a close eye here—perfectly melted cheese is the crowning glory. After broiling, sprinkle minced fresh parsley over the cheese for a fresh note if you like.

Step 5: Serve with Au Jus on the Side

Ladle about three-quarters of a cup of the warm au jus into small ramekins for dipping. Serve these alongside your melty, meaty sandwiches so everyone can dunk each bite into that rich, flavorful broth. It’s all the magic of a classic French dip, elevated with grilled Gruyère cheese and garlic-infused rolls.

Garnishes

A sprinkle of minced fresh flat-leaf parsley adds a lovely pop of green and a bright, herbaceous lift to the sandwich. If you want to play with texture, a few crunchy pickles on the side also pair wonderfully and help cut through the richness.

Side Dishes

French fries or thin-cut potato chips are the classic companions, providing a satisfying crunch to complement the tender sandwich. For a lighter contrast, a crisp green salad with a zesty vinaigrette or tangy coleslaw is refreshing and balances the hearty meal perfectly.

Creative Ways to Present

For a dinner party, serve your French Dip Sandwich with Au Jus and Grilled Gruyère Recipe on a wooden board surrounded by ramekins of au jus and assorted mustards or horseradish cream. You can also cut the sandwiches into smaller slider-sized portions for appetizers, making it easy for guests to savor that savory goodness in a bite-sized form.

Make Ahead and Storage

Storing Leftovers

If you have any leftover steak or assembled sandwiches, wrap them tightly in plastic wrap or store in an airtight container and refrigerate for up to 2 days. Keep the au jus separate in a sealed jar or container to retain its flavor and prevent sogginess.

Freezing

While it’s best enjoyed fresh, you can freeze cooked steak slices in an airtight container for up to 3 months. Freeze your au jus separately in freezer-safe bags or containers. It’s not recommended to freeze assembled sandwiches because the bread and cheese textures change after thawing.

Reheating

Warm leftover steak gently in a skillet or microwave just until heated through to avoid drying it out. Reheat the au jus on the stove until steaming. To refresh sandwiches, toast the rolls briefly and add cheese melted under the broiler again for that freshly made vibe.

FAQs

What’s the best cut of beef for this French Dip Sandwich with Au Jus and Grilled Gruyère Recipe?

Skirt or flank steak work best because they sear quickly and have great flavor with relatively affordable prices. They also slice thinly against the grain for tender bites, making them perfect for this recipe.

Can I use a different cheese instead of Gruyère?

Absolutely! Swiss cheese is a common and delicious substitute that melts well and pairs nicely with beef. For a sharper bite, try aged cheddar or fontina, but the classic nutty Gruyère really shines here.

Is the au jus complicated to make?

Not at all! It’s essentially a seasoned beef broth enhanced with herbs, spices, and Worcestershire sauce. It comes together quickly on the stovetop but adds incredible depth to the sandwich.

Can I make this recipe ahead of time for a party?

You can prep the steak and au jus in advance but it’s best to assemble and broil the sandwiches right before serving for that perfect melty cheese and fresh-toasted bread experience.

How do I get the rolls crispy without drying them out?

Butter and seasoning inside the rolls add moisture and flavor, while broiling just briefly melts the cheese and crisps the edges without making the bread tough or dry. Keep a close eye to avoid burning.
