Method
Bake the roll base
- Preheat the oven to 350°F, then place the bottom halves of the rolls in a baking dish in an even layer.
- Add a layer of thinly sliced roast beef and top with provolone cheese slices evenly over the rolls.
- Place the remaining roll halves over the filling, stacking to cover the cheese.
Make the butter topping
- Whisk the melted butter with Worcestershire sauce, garlic powder, and dried onion flakes, then brush the mixture over the tops.
Bake and serve
- Bake for 20-25 minutes at 350°F until the tops are golden and the cheese is fully melted.
- Warm the beef broth until hot, then serve alongside the squares for dipping as au jus.
Notes
Pro tip: Slice all rolls in one continuous piece for easier assembly, then separate them after baking. Refrigerate leftovers in a covered container up to 3 days; rewarm in the oven at 300°F until hot. Freeze baked squares for up to 2 months (freeze without au jus), then reheat until warmed through. For a lighter version, use reduced-fat provolone while keeping the butter topping the same for proper browning.
