Arby’s Roast Beef Recipe: Slow-Roasted for That Signature Juicy Stack

I’ve perfected a roast beef recipe that’s remarkably similar to Arby’s famous thinly sliced roast beef. This foolproof method ensures tender, juicy meat every time. The key is slow roasting to achieve that signature tenderness.

By following my detailed instructions, you’ll be able to create a delicious roast beef sandwich with horseradish sauce and your favorite toppings on a soft bun. Let’s get started!

Ingredients for Arby’s Roast Beef

Gather these quality ingredients for a roast beef experience that’s remarkably close to Arby’s.

The top round roast is crucial here. Look for a lean cut at your local butcher or quality grocery store. Costco often has great deals on larger roasts. For the horseradish sauce, you can make your own or use store-bought—Trader Joe’s has a great version.

No Worcestershire sauce? You can make a decent substitute with soy sauce, vinegar, and a pinch of sugar. If you can’t find provolone, Swiss or cheddar work too. For the roast, if you prefer a different cut, top sirloin can be a good alternative, though it may be slightly less tender.

This roast beef keeps beautifully—slice leftovers thinly and store in an airtight container for up to 4 days in the fridge. The horseradish sauce will keep for 2 weeks in the fridge. Reheat gently in the oven or microwave before serving.

Step-by-Step Instructions for Arby’s Roast Beef Recipe

Mastering this iconic roast beef recipe is easier than you think with these detailed steps.

Step 1: Prepare and Season the Top Round Roast

Start by preheating your oven to 325°F. While it’s heating up, season the 2.5 lb Top Round Roast generously with 1 tbsp Salt, 1 tsp Black Pepper, 1 tsp Garlic Powder, and 1 tsp Onion Powder. Make sure to coat the roast evenly on all sides. I like to press the seasonings into the meat to ensure they stick.

The key here is to create a flavorful crust on the roast. By using kosher salt and freshly ground black pepper, you’ll get a more complex flavor profile. Don’t be shy with the seasoning – it’s what makes Arby’s roast beef stand out.

Step 2: Sear the Roast and Start the Cooking Process

Heat 2 tbsp Olive Oil in a large oven-safe skillet over high heat. Once the oil is hot and shimmering, sear the seasoned roast for 2-3 minutes per side until you get a nice brown crust. This step is crucial for locking in the juices and creating that signature flavor.

After searing, transfer the skillet to the preheated oven. Roast the beef for about 2 hours, or until it reaches your desired level of doneness. For medium-rare, aim for an internal temperature of 135°F. Use a meat thermometer to check the temperature, especially in the thickest part of the roast.

Step 3: Prepare the Au Jus and Rest the Roast

While the roast is cooking, prepare the au jus. In a small saucepan, combine 1 cup Beef Broth and 2 tbsp Worcestershire Sauce. Bring this mixture to a simmer over medium heat and let it reduce slightly for about 5-7 minutes. This will intensify the flavor, making it perfect for dipping your roast beef sandwiches.

Once the roast is done, remove it from the oven and let it rest for 15-20 minutes before slicing. This resting period is crucial as it allows the juices to redistribute throughout the meat, ensuring it’s tender and juicy. Tent the roast loosely with foil to keep it warm during this time.

Step 4: Slice and Assemble the Roast Beef Sandwiches

After the roast has rested, slice it thinly against the grain using a sharp knife. I prefer using an electric knife for this task as it makes getting thin, uniform slices much easier. You should be able to get nice, thin slices that are perfect for sandwiches.

To assemble the sandwiches, place the sliced roast beef onto 4 whole Soft Buns. You can add 4 slices Provolone Cheese if you like, although it’s optional. Top with 4 cups Fresh Lettuce and 4 slices Tomato Slices. Serve with the prepared au jus on the side for dipping, and don’t forget to have 0.5 cup Horseradish Sauce available for those who prefer a bit of heat.

Pro Cooking Tips for Perfect Results

Temperature Control Mastery

The secret to perfect roast beef is maintaining precise temperature control. I preheat my oven to 325°F and use an instant-read thermometer to check the roast’s internal temperature. For medium-rare, aim for 135°F in the thickest part.

Searing Techniques

A proper sear creates the flavor foundation. Heat 2 tbsp Olive Oil in a hot skillet until shimmering, then sear the seasoned roast for 2-3 minutes per side. This creates a beautiful crust that locks in juices. I like to use a cast-iron skillet for even heat distribution.

Resting is Essential

After roasting, let the meat rest for 15-20 minutes before slicing. Tent it loosely with foil to keep it warm. This resting period allows juices to redistribute, making the beef tender and juicy. I learned this technique from my Irish-Italian grandmother, who always emphasized patience in cooking.

Slicing Against the Grain

For the thinnest slices, cut against the grain using a sharp knife. I prefer an electric knife for this task as it makes getting uniform, thin slices much easier. Slice just before serving to maintain the roast’s warmth and texture. Thin slices are key to replicating Arby’s signature style.

Au Jus Preparation

While the roast cooks, prepare the au jus by simmering 1 cup Beef Broth with 2 tbsp Worcestershire Sauce over medium heat for 5-7 minutes. This reduction intensifies the flavor, making it perfect for dipping. I often make extra au jus to store for later use.

Assembly and Serving

Assemble the sandwiches by placing thinly sliced roast beef onto soft buns. Add toppings like provolone cheese, fresh lettuce, and tomato slices. Serve with au jus on the side for dipping and offer horseradish sauce for those who like a spicy kick. This presentation replicates the Arby’s experience at home.
