Ultimate French Dip Sandwich
This Ultimate French Dip Sandwich is loaded with finely chopped ribeye, sweet sautéed onions, and melty Swiss cheese, all served with a rich, deeply savory au jus. Every bite is tender, juicy, and made even better when dunked into that warm, flavorful broth.
Ingredients
AU JUS
- 3 tbsp butter
- 1 sweet onion, thinly sliced
- 2 cups beef broth
- 1 sprig rosemary
- 1 tbsp Worcestershire sauce
- Salt to taste
- Black pepper to taste
STEAK
- 1 lb shaved ribeye
- 1 diced yellow onion
- 1 tbsp oil
- 1 tsp salt
- 1 tsp black pepper
FOR ASSEMBLY
- 4 hoagie rolls
- 8 slices Swiss cheese
Instructions
- In a saucepan over medium-low heat, melt the butter and add the sliced sweet onion. Cook for 15–20 minutes, stirring occasionally, until the onions are deeply caramelized and golden brown without burning.
- Pour in the beef broth, then add rosemary, Worcestershire sauce, salt, and black pepper. Simmer gently for 10 minutes to allow the flavors to develop, then strain through a fine mesh strainer and keep warm for serving.
- Preheat a griddle or large skillet to high heat, about 450°F, and add oil. Sauté the diced onion for 3–5 minutes until softened and lightly browned, then move to the side of the griddle.
- Add the shaved ribeye to the hot surface and season evenly with salt and black pepper. Let it sear for 1–2 minutes before chopping finely and mixing with the sautéed onions once the steak is nearly cooked through.
- Form the steak mixture into four portions and top each with Swiss cheese. Allow the cheese to melt completely, about 1–2 minutes, until gooey and fully covering the beef.
- Scoop each portion into a hoagie roll and serve immediately alongside the warm au jus. Dunk generously before each bite for the ultimate juicy, flavor-packed sandwich experience.
