A tender slow-cooked beef sandwich with caramelized onions and savory au jus, perfect for a comforting homemade dinner.
Let the beef rest before slicing to retain juices. Toast bread just before assembling to prevent sogginess. If au jus is too thin, simmer uncovered to concentrate flavors. For deeper flavor, add a splash of red wine to broth while cooking. Use gluten-free rolls and broth for gluten-free version. Dairy-free butter alternatives can be used for toasting.
