Instructions

Recipe For French Dip Sandwiches With Roast Beef

Step 1: Prepare the Beef

Season the beef roast generously with salt, pepper, and garlic powder. Heat olive oil in a skillet over medium-high heat and sear the beef on all sides until browned, about 3-4 minutes per side. This step locks in the flavors and adds a delicious crust to the beef.

Step 2: Slow Cook the Beef

Transfer the seared beef to a slow cooker or oven-safe pot. Add the sliced onion, beef broth, and Worcestershire sauce. Cover and cook on low for 8 hours in a slow cooker or at 300°F in the oven until the beef is fork-tender.

Step 3: Prepare the Au Jus

Once the beef is cooked, remove it from the pot and let it rest. Strain the cooking liquid to remove the onions and any bits, then return the liquid to the pot. Keep warm on the stove over low heat for dipping.

Step 4: Assemble the Sandwiches

Slice the beef thinly against the grain. Split the hoagie rolls and layer the beef and provolone cheese inside. Toast in the oven at 350°F for 5-7 minutes until the cheese is melted and the bread is crispy.

Step 5: Serve and Enjoy

Serve the sandwiches hot with a side of the warm au jus for dipping. The combination of tender beef, melted cheese, and crispy bread dipped in rich au jus is irresistible.

Tips and Tricks

For an even richer flavor, you can add a splash of red wine to the au jus. If you’re short on time, using a pressure cooker can reduce the cooking time significantly. Always let the beef rest before slicing to ensure it stays juicy. For a crispier sandwich, broil the assembled sandwiches for the last minute of toasting. Experiment with different cheeses like Swiss or mozzarella for a new twist.

Recipe Variations

  • Try using different types of bread, such as baguettes or ciabatta, for a different texture.
  • Add sautéed mushrooms and onions to the sandwich for extra flavor.
  • For a spicy kick, mix some horseradish into the au jus.
  • Substitute the beef with lamb or pork for a different taste.
  • Make it vegetarian by using portobello mushrooms instead of beef.
