Leftover Prime Rib French Dip Sandwich
Tender slices of prime rib, melty cheese, crusty bread, and rich au jus for dipping… this sandwich is fast, comforting, and dangerously good.
Ingredients
- 1 lb Leftover prime rib , thinly sliced
- 4 Hoagie rolls or French rolls
- 4 Slices of provolone cheese (Swiss works too!)
- 1 Small onion , thinly sliced (optional but amazing)
- 1 tbsp butter
For the Au Jus
- 2 cups beef broth
- ½ cup leftover prime rib drippings , au jus, or beef stock
- 1 teaspoon Worcestershire sauce
- 1 teaspoon soy sauce
- ½ teaspoon garlic powder
- Salt and black pepper , to taste
Instructions
Step 1: Make the Au Jus.
- In a saucepan over medium heat, add: beef broth, prime rib drippings, Worcestershire sauce, soy sauce, and garlic powder. Bring to a gentle simmer. Taste and season with salt and pepper if needed. Keep warm on low. 💡 This is not gravy—don’t thicken it! We want it dunk-able.
Step 2: Warm the Prime Rib (Gently!)
- Pre-heat oven broiler (for step 3). In a skillet over low heat, melt the butter. Add sliced onions (if using) and cook until soft and golden. Add the sliced prime rib and just warm it through—do not cook it. We’re keeping that beef tender and juicy, not turning it into shoe leather. 😉
- Step 3: Assemble the Sandwiches
- Slice rolls lengthwise (don’t cut all the way through). Fill with warm prime rib and top with provolone cheese. Place under the broiler for 1–2 minutes, just until the cheese melts and the bread gets lightly toasty.
Step 4: Serve & Dip!
- Serve sandwiches hot with small bowls of warm au jus on the side. ⚠️ Warning: Double-dipping may occur.
