Step‑by‑Step Instructions for Slow Cooker Arby’s Roast Beef and Cheddar Sandwiches

Start by placing a quality 2-3 pound chuck roast at the bottom of your slow cooker. This cut will become tender and flavorful as it cooks. Ensure the roast is spread evenly in the cooker to allow for even heat distribution.
Step 2: Season the Beef
Next, sprinkle dried minced onion and Montreal steak seasoning generously over the surface of the roast. Ensure to cover it well, pressing lightly to help the seasonings adhere. This step is crucial for infusing your roast beef and cheddar sandwiches with robust flavor as they slowly cook.
Step 3: Add Flavorings
Pour Worcestershire sauce and 1½ cups of Arby’s sauce evenly over the seasoned roast. The combination of these sauces will enhance the flavor profile and provide that signature taste found in the iconic roast beef and cheddar sandwiches. Make sure the beef is well-coated for maximum flavor infusion.
