How to Make French Dip Sandwiches with Melted Gruyère and Rich Au Jus Recipe

Step 1: Prepare and Sear the Steak

Start by seasoning your steak generously with kosher salt and freshly cracked black pepper. Heat a large cast-iron skillet over high heat to get it smoking hot, then sear the steak for about 3 minutes per side to achieve a perfect medium-rare. Using an instant-read thermometer aiming for 135°F guarantees tender, juicy meat. Let that steak rest for 5 minutes—that’s the secret to preserving all those meaty juices before slicing it thinly against the grain for the best texture.

Step 2: Make the Rich Au Jus

While the steak rests, it’s time to make your soul-warming au jus. In a saucepan set to medium heat, whisk together beef stock, dried thyme, kosher salt, Worcestershire sauce, garlic powder, and onion powder. Let this simmer gently for 5 minutes, stirring occasionally; this concentrates the flavors into a rich, savory broth that’s perfect for dipping each sandwich. The aroma alone will have you ready to eat before the sandwiches are even ready!

Step 3: Prepare the Rolls

Butter the inside of each roll with the softened salted butter, then sprinkle evenly with garlic powder. This is where simple ingredients elevate the sandwich, as the buttery, garlicky interior crisps under broiling heat. Place the rolls open-faced on a rimmed baking sheet—this setup makes it easy to assemble and broil everything quickly.

Step 4: Assemble and Broil the Sandwiches

Dip the thin slices of steak quickly into the warm au jus to soak up that deep flavor before piling them onto one side of each roll. Top each with about ½ cup of grated Gruyère cheese, then transfer the baking sheet under a preheated broiler on HIGH. Watch closely and broil just until the cheese melts and turns bubbly, about 2 minutes. This step turns the sandwich into a gooey, irresistible masterpiece in no time.

Step 5: Serve with Rich Au Jus

For the final flourish, sprinkle minced fresh parsley over the sandwiches for a pop of color and freshness. Ladle about ¾ cup of the au jus into small dipping ramekins beside each sandwich and get ready for an unforgettable meal filled with luxurious flavors and textures.

Garnishes

A sprinkle of fresh flat-leaf parsley brightens the rich colors and flavors of these French Dip Sandwiches with Melted Gruyère and Rich Au Jus Recipe. You can also add pickled peppers or thinly sliced red onions for a zing that contrasts beautifully with the beefy, cheesy layers.

Side Dishes

Classic sides like crispy shoestring fries or a light, tangy coleslaw make perfect companions, balancing the richness of the sandwich. A simple mixed greens salad dressed with a lemon vinaigrette adds just enough acidity to clear the palate between savory bites.

Creative Ways to Present

For a fun twist, turn these sandwiches into sliders with smaller rolls for a party platter, or serve them open-faced on wooden boards for a rustic yet elegant presentation. Using ramekins for the au jus keeps the dipping organized and adds a lovely touch to your table setting.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have any leftovers from these French Dip Sandwiches with Melted Gruyère and Rich Au Jus Recipe, store the sliced steak and rolls separately in airtight containers in the refrigerator. Keep the au jus in its own container to maintain the sandwich’s freshness and moisture when reheating.

Freezing

You can freeze the cooked steak slices wrapped tightly in plastic wrap and foil for up to 3 months. Frozen rolls don’t reheat as well, so it’s best to freeze the steak and prepare fresh rolls later. Freeze the au jus in portions so you can easily thaw just what you need for your next craving.

Reheating

To reheat, warm the steak gently in a skillet or microwave dipped briefly in the au jus to keep it tender. Toast the rolls separately with garlic butter to restore their crunch. Assemble the sandwich fresh and melt some Gruyère under the broiler until bubbly—this revives all the flavors just like the original.

FAQs

What cut of steak is best for this recipe?

Skirt or flank steak works wonderfully because they’re flavorful and tender when sliced thinly against the grain. These cuts sear quickly and complement the robust au jus perfectly.

Can I use a different cheese instead of Gruyère?

Absolutely! Swiss cheese is a great alternative with similar melting qualities and nutty flavor. For a sharper bite, aged cheddar can also work, though it changes the flavor profile slightly.

How long can I store leftover au jus?

You can refrigerate leftover au jus in an airtight container for up to 4 days. Just reheat gently before serving to maintain its rich flavor.

Is there a vegetarian alternative for the au jus?

While traditional au jus relies on beef stock, you can create a vegetarian version with mushroom broth and soy sauce to replicate that umami richness. It won’t be exactly the same, but it’s a delicious and inclusive option.

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

Yes, prep the steak and au jus in advance, then reheat and assemble right before serving. Preparing rolls with garlic butter ahead and broiling them last-minute keeps the sandwiches fresh and impressive for your guests.
