Preheat the oven to 375°F (190°C) and spray the baking dish with non-stick cooking spray.

Unroll one can of refrigerated crescent rolls and lay the dough evenly across the bottom of the baking dish.

Spread a layer of deli-sliced roast beef over the crescent roll dough.

Sprinkle grated Swiss cheese on top of the roast beef.

In a small bowl, mix together the dry onion soup mix, melted butter, Worcestershire sauce, and garlic powder, then drizzle over the cheese.

Unroll the second can of crescent rolls and lay it over the filling.

Bake for 15 to 20 minutes until the top is golden brown.

While baking, heat the beef broth in a pot over medium heat.

Once baked, allow to cool for 5 to 10 minutes before slicing into squares.

Serve warm with heated beef broth for dipping.
