For the roast beef, top round is ideal—its leanness gives that tender, almost-melted texture. Most grocery stores carry it, but if you’re at Whole Foods, ask for prime grade. Trim any excess fat before roasting. The key is cooking it low and slow to that perfect medium-rare. Let it rest before slicing thin.

No sharp cheddar? Mix regular cheddar with a bit of Parmesan for similar sharpness. If you can’t find unsalted butter, use salted and reduce the added salt. For an extra-creamy sauce, add 1-2 tablespoons of heavy cream. The dried mustard adds depth—don’t skip it. Worcestershire sauce is crucial for that authentic Arby’s flavor.

Leftover roast beef keeps for 3-4 days in the fridge. Slice it thin and freeze for future sandwiches. The cheddar sauce freezes beautifully too—portion into ice cube trays for easy reheating. Reheat gently on low heat, whisking constantly to prevent separation.

Step-by-Step Instructions for Arby’s Beef and Cheddar Double

Follow these precise steps to create the perfect Arby’s Beef and Cheddar Double at home.

🔥 Step 1: Prepare the Roast Beef

Preheat your oven to 325°F. Season the 1.5 lb Top Round Roast Beef with 1 tsp Kosher Salt and 0.5 tsp Black Pepper, making sure to coat all surfaces evenly. Place the roast in a roasting pan and roast in the preheated oven for about 2 hours, or until it reaches your desired level of doneness. Use a meat thermometer to check for an internal temperature of 135°F for medium-rare or 145°F for medium. Once done, let the roast rest for 15-20 minutes before slicing thinly against the grain.

While the beef is resting, you can start preparing the cheddar sauce. The thinly sliced roast beef will be easier to assemble in the sandwiches later.

🍳 Step 2: Make the Cheddar Sauce

In a medium saucepan, melt 4 tbsp Unsalted Butter over medium heat. Once melted, add 2 tbsp All-Purpose Flour and whisk to form a smooth roux, cooking for 1-2 minutes. Gradually pour in 1 cup Whole Milk, whisking constantly to prevent lumps. Bring the mixture to a simmer and cook until it thickens, about 5-7 minutes. Remove from heat and stir in 1 cup Cheddar Cheese until fully melted and smooth. Add 0.5 tsp Dried Mustard and 1 tsp Worcestershire Sauce, and season with additional Kosher Salt and Black Pepper to taste.

The cheddar sauce should be creamy and well-seasoned, coating the back of a spoon. Keep it warm on low heat while you assemble the sandwiches.

🥘 Step 3: Assemble the Arby’s Beef and Cheddar Double

Slice the rested roast beef into thin strips. Toast the 4 whole Buns lightly on a griddle or in the oven until they are slightly crispy. To assemble each sandwich, place a layer of sliced roast beef on the bottom bun, followed by a generous amount of the warm cheddar sauce. Top with the other bun half. For a Double, repeat the layers: add more roast beef, another layer of cheddar sauce, and finish with the top bun.

Serve immediately while the roast beef is still warm and the cheddar sauce is gooey. The combination of tender roast beef, creamy cheddar sauce, and soft buns will make this Arby’s Beef and Cheddar Double a hit.

Troubleshooting This Recipe

Common Roast Beef Issues

One of the most common problems with roast beef is overcooking. I always check the internal temperature with a meat thermometer to avoid this. For medium-rare, aim for 135°F. Letting it rest for 15-20 minutes before slicing makes a huge difference in tenderness.

Cheddar Sauce Troubleshooting

If your cheddar sauce breaks or separates, don’t panic. This usually happens when it’s overheated. Simply remove it from heat immediately and whisk in 1-2 tablespoons cold butter to stabilize the emulsion. If it’s too thick, thin it with a splash of whole milk while whisking.

Assembly Challenges

Sometimes the roast beef can be tricky to slice thinly. I find that partially freezing the roast for 30-45 minutes makes it easier to get those perfect thin slices. For the sandwiches, toasting the buns lightly prevents them from getting soggy under the cheddar sauce. 🔥

Reheating Leftovers

To reheat leftover roast beef without drying it out, slice it thinly and warm it in a saucepot with a bit of beef broth over low heat. For the cheddar sauce, reheat it gently in a saucepan over low heat, whisking constantly. You can also reheat both components together in a microwave-safe bowl in 30-second increments, stirring between each interval.

Customization Tips

If you want to get creative with this recipe, try adding some horseradish to the cheddar sauce for an extra kick. You can also experiment with different types of cheese, like mixing in some Gouda or Parmesan with the cheddar for a unique flavor profile. For a spicy twist, add some diced jalapeños to the sauce.

Storage Solutions

For storing leftovers, keep the roast beef and cheddar sauce separate. Store them in airtight containers in the refrigerator for up to 3-4 days. When you’re ready to enjoy them again, the roast beef can be reheated as mentioned earlier, and the cheddar sauce can be reheated on low heat, whisking constantly to prevent separation. ❄️
