A delightful twist on the classic French Onion Beef Au Jus, this recipe offers a rich and flavorful beef sandwich experience.
Slice the onions into thin rings.
Use a sharp knife to ensure even slices for uniform cooking.
Heat butter in a large skillet over medium heat and add the onions. Cook until caramelized.
Stir occasionally to prevent burning and achieve a golden brown color.
Combine soy sauce, garlic, coffee, and 2 cups of water in a bowl.
Mix thoroughly to ensure the flavors are well combined.
Place the beef roast in a Dutch oven and pour the broth mixture over it. Add the caramelized onions.
Ensure the beef is fully submerged for even cooking.
Cover and bake in a preheated oven at 325°F for 2.5 hours or until the beef is tender.
Check occasionally to ensure the liquid level is sufficient.
Remove the beef and let it rest for 20 minutes before slicing thinly.
Resting allows the juices to redistribute for a more flavorful result.
Slice the bread rolls lengthwise, butter them, and toast in the oven at 375°F until golden.
Toast just before serving to maintain crispness.
Assemble the sandwiches by layering beef slices, onions, and cheese on the bread. Broil until the cheese melts.
Keep an eye on the broiler to prevent overcooking.
Serve the sandwiches with a side of the hot broth for dipping.
Serve immediately for the best experience.
