Hot Roast Beef Sandwich Recipe With Au Jus: Shaved Thin and Dipped to Perfection

There’s nothing like a perfect hot roast beef sandwich with au jus to bring comfort to the table. I developed this recipe after years of craving that deli-style experience at home, and it delivers every time.

The secret is in the thinly shaved beef, cooked just right to stay tender, and a rich, savory au jus that enhances every bite. This sandwich is all about layering flavors—warm beef, melted cheese, and a crusty roll that holds up to the dipping.

What you get is a meal that feels indulgent but comes together with simple, foolproof steps. The au jus is the star, made from the beef’s natural juices for a depth of flavor that can’t be matched.

Ideal for a cozy dinner or a satisfying lunch, this dish is a celebration of classic comfort food done right.

The beef is the foundation here. Top round roast is lean but stays tender when sliced thin—ask the butcher at Whole Foods or Kroger to shave it for you (saves time and ensures even slices). Look for bright red color with minimal fat. If buying pre-sliced, Boar’s Head makes a solid deli-style roast beef that works in a pinch.

No top round? Sirloin tip is a good swap, though slightly richer. For the au jus, beef bouillon cubes dissolved in hot water can replace broth. Out of Worcestershire? A1 Steak Sauce adds a similar tang. Provolone not your thing? Swiss or mozzarella melt just as well. The rolls can be hoagie or sub rolls if French aren’t available.

The au jus tastes even better the next day—store in an airtight container for up to 4 days. Sliced beef keeps 3-4 days in the fridge, but it’s best used fresh. To freeze, wrap beef tightly in plastic and foil for up to 3 months.

Step-by-Step Instructions for Hot Roast Beef Sandwich With Au Jus

Here’s the method I use to get that perfect shaved beef and rich dipping sauce every time.

Step 1: Season and Sear the Beef Top Round Roast

Pat the 2 lb Beef Top Round Roast dry with paper towels. I mix together 1 tsp Garlic Powder, 1 tsp Onion Powder, 1.5 tsp Kosher Salt, and 1 tsp Black Pepper to create a simple rub, then coat the roast evenly on all sides. Let it sit at room temperature for 20 minutes while your oven preheats.

Heat a large oven-safe pot or Dutch oven over medium-high heat. Add the roast and sear on all sides until deeply browned, about 3-4 minutes per side. You’re looking for a dark crust—this adds incredible flavor to both the beef and the au jus later.

Step 2: Roast the Beef to Medium-Rare

Transfer the seared roast to the preheated 375°F oven. Roast uncovered for 20-25 minutes per pound until the internal temperature reaches 135°F for medium-rare. For this 2 lb Beef Top Round Roast, that’s about 45-50 minutes total.

Remove from the oven and let it rest on a cutting board for 15 minutes before slicing. The internal temperature will rise to 140-145°F during resting. This rest period is crucial—it allows the juices to redistribute, so your sandwiches won’t be dry.

Step 3: Make the Au Jus While Beef Rests

Place the pot with the beef drippings on the stovetop over medium heat. Add the thinly sliced Yellow Onion and cook for 2-3 minutes until softened. Pour in the 2 cups Beef Broth, 2 tbsp Worcestershire Sauce, and 1 tbsp Soy Sauce.

Add the 2 whole Fresh Thyme Sprigs if using. Simmer for 8-10 minutes until the liquid reduces by about a third and the flavors meld together. Strain out the solids and keep the au jus warm while you assemble the sandwiches.

Step 4: Slice Beef, Toast Rolls, and Assemble

Slice the Beef Top Round Roast as thinly as possible against the grain—I aim for paper-thin slices. Split the 4 whole Crusty French Rolls and spread each with ½ tbsp Unsalted Butter. Toast in a skillet over medium heat for 1-2 minutes until golden brown.

Layer the shaved beef on the bottom half of each roll, then top with thinly sliced Provolone Cheese. Return to the skillet for 1-2 minutes until the cheese melts. Cap with the top half of the roll and serve immediately with small cups of the warm au jus for dipping.

Perfect Pairings for hot roast beef sandwich recipe with au jus

Classic Side Pairings

I always serve these sandwiches with crispy garlic fries—toss 1 lb frozen fries with 1 tbsp olive oil and 1 tsp garlic powder before baking. The saltiness complements the rich au jus perfectly. 💛

Lighter Options

A simple green side salad with 2 cups mixed greens, ½ cup cherry tomatoes, and balsamic vinaigrette cuts through the richness. I use the same dressing from my Boston deli days—equal parts oil and vinegar with a touch of Dijon.

Beer Pairings

For beer lovers, a dark lager like Guinness or Negra Modelo stands up to the beef’s bold flavors. The roasted notes in the beer mirror the seared crust on the meat. I keep a few in my fridge for exactly this meal.

Wine Selections

A full-bodied Cabernet Sauvignon or Malbec works beautifully—the tannins soften when paired with the fatty beef. For white wine fans, try a buttery Chardonnay to balance the au jus. I’ve tested both with this recipe.

Dessert Follow-Up

End with something light, like vanilla ice cream with hot fudge. The cool sweetness resets your palate after the savory sandwich. It’s my go-to after comfort meals like this one.

Condiment Bar

Set out horseradish sauce, spicy mustard, and pickled jalapeños for customization. These add extra layers of flavor without overpowering the dish. My family always fights over the jalapeños.
