Homemade Beef Cheddar Melt: Arby’s-Inspired Comfort Sandwich

1. Prepare the Arby’s-Style Sauce

In a small bowl, whisk together ketchup, brown sugar, apple cider vinegar, Worcestershire sauce, garlic powder, and onion powder.

Set aside to allow flavors to meld.

2. Make the Cheddar Cheese Sauce

Melt butter in a small saucepan over medium heat.

Stir in flour and cook for 1 minute, stirring constantly until foamy.

Gradually pour in milk while whisking, simmering until thickened (about 5 minutes).

Remove from heat and stir in shredded cheddar until smooth.

3. Warm the Roast Beef

Add beef broth to a skillet and bring to a simmer.

Separate roast beef slices to avoid clumping and warm in batches for 1–2 minutes.

Lift out with tongs and drain.

4. Assemble the Sandwiches

Spread Arby’s-style sauce on the bottom half of each bun.

Layer on warm roast beef.

Drizzle generously with cheddar cheese sauce.

Top with the other bun half and serve immediately.
