Ingredients Method Notes

Ingredients
  

  • Cooking spray
  • 2 8-oz. tubes refrigerated crescent rolls
  • 4 tbsp butter divided
  • 2 medium onions thinly sliced
  • 4 sprigs fresh thyme divided
  • Kosher salt and black pepper
  • 1/4 cup whole-grain mustard
  • 1/2 lb deli roast beef patted dry
  • 9 slices provolone cheese
  • 1 tbsp freshly chopped parsley
  • 1 cup low-sodium beef broth
  • 1 tbsp Worcestershire sauce
  • 1 clove garlic minced
  • Remaining 2 sprigs thyme stripped

Method
 

  1. Melt 2 tbsp butter in a skillet over medium heat. Add sliced onions, 2 sprigs thyme, salt, and pepper. Cook 10–12 minutes until softened and lightly golden.
  2. Preheat oven to 375°F (190°C) and spray a 9x13-inch baking dish. Press one tube of crescent rolls into the dish to form a base.
  3. Spread mustard over the dough. Layer roast beef, provolone cheese, and caramelized onions.
  4. Unroll second crescent sheet and place on top. Seal edges. Brush with 1 tbsp melted butter and sprinkle with parsley.
  5. Bake 35 minutes until golden (cover with foil if browning too fast).
  6. For the au jus, melt remaining 1 tbsp butter in a skillet. Add garlic and cook 30 seconds. Stir in broth, Worcestershire, thyme, salt, and pepper. Simmer 10 minutes until slightly reduced.
  7. Cut baked squares and serve warm with au jus for dipping.

Notes

Pat roast beef dry to prevent soggy crust. For deeper au jus flavor, add a splash of red wine. Excellent for game days, holidays, and make-ahead prep.
