Preheat your oven to 375°F (190°C). Spray a 9x13 inch baking dish with non-stick cooking spray.

Unroll one can of refrigerated crescent rolls and lay the dough into the baking dish, pressing it into the bottom.

Distribute deli roast beef across the crescent roll base and layer Swiss cheese slices over the beef.

Mix the dry onion soup mix, melted butter, Worcestershire sauce, and garlic powder in a bowl. Drizzle over the Swiss cheese layer.

Unroll the second can of crescent rolls over the top, pinching seams together to prevent filling leaks.

Bake for 15-20 minutes until golden brown and fully cooked.

While baking, heat beef broth in a saucepan over medium heat for dipping.

After baking, let cool for a few minutes, cut into squares, and serve warm with beef broth.
