Ingredients
1 Pound Deli Roast Beef
The star of the sandwich. Thinly sliced deli roast beef warms quickly and absorbs the rich flavors of the broth mixture without becoming tough or dry.
1 Can Beef Broth
Adds moisture and deep beefy flavor while helping keep the roast beef tender and juicy.
1 Packet Onion Soup Mix
This simple ingredient enhances the broth with savory seasonings, onion flavor, and umami richness that mimics slow-cooked roast beef.
Cheese Sauce
The creamy, velvety cheese sauce creates the signature cheddar flavor that makes this sandwich irresistible. Use prepared cheddar cheese sauce or make your own.
BBQ Sauce
Provides the sweet and tangy contrast that balances the richness of the beef and cheese. A smoky barbecue sauce works especially well.
Sandwich Buns
Soft sandwich buns hold all the delicious fillings together. Toasting them adds texture and prevents sogginess.
How to Make Copycat Arby’s Roast Beef & Cheddar
Step 1: Prepare the Flavorful Broth
In a medium saucepan, combine the beef broth and onion soup mix.
Place the pan over medium-high heat and bring the mixture to a gentle boil. Stir occasionally to dissolve the soup mix completely.
Step 2: Warm the Roast Beef
Once the broth reaches a boil, remove the saucepan from the heat.
Add the sliced roast beef directly into the hot broth mixture. Allow it to sit for 2–3 minutes, gently stirring occasionally.
This method warms the meat perfectly while keeping it tender and juicy.
Step 3: Toast the Buns
While the beef is warming, lightly toast the sandwich buns.
You can toast them in a toaster oven, skillet, or under the broiler for 1–2 minutes until lightly golden.
Step 4: Assemble the Sandwiches
Place a generous portion of warm roast beef on the bottom half of each bun.
Spoon a hearty layer of cheese sauce over the beef.
Drizzle BBQ sauce over the cheese layer.
Top with the remaining bun halves.
Step 5: Serve and Enjoy
Serve immediately while warm and enjoy the perfect combination of tender beef, creamy cheddar, and tangy barbecue sauce.
