Ingredients

1 teaspoon olive oil
1/2 medium onion, diced
1 clove garlic, minced
2 cups beef stock (low sodium preferred)
2 tablespoons Worcestershire sauce
2 teaspoons soy sauce
2 beef bullion cubes (optional)
1 pound deli sliced roast beef
Salt and pepper, to taste
4 French rolls (for serving)

Instructions

Step 1: Heat the olive oil in a medium saucepan over medium heat. Add the diced onion and cook for 3-4 minutes until it becomes semi-translucent. Then add the minced garlic and cook for 1 minute more.
Step 2: Pour in the beef stock, Worcestershire sauce, soy sauce, and add the beef bullion cubes if using. Bring the mixture to a boil and continue boiling for 4-5 minutes until the bullion dissolves completely.
Step 3: Taste the au jus carefully and season with salt and pepper as desired.
Step 4: Add the sliced roast beef to the saucepan and let it warm in the hot au jus until heated through.
Step 5: Optional: Lightly toast the French rolls by placing them cut side up under the broiler for a few minutes until they are toasty but not burnt.
Step 6: Pile the warmed beef onto the toasted rolls and serve immediately with a cup of the au jus for dipping.

Tips & Variations

For extra flavor, add a splash of red wine to the au jus while boiling.
Swap the roast beef with thinly sliced prime rib for a richer sandwich.
Try adding melted cheese like provolone or Swiss on the sandwich before serving.
If you want a thicker au jus, simmer it longer to reduce the liquid slightly.

Storage

Store leftover roast beef and au jus separately in airtight containers in the refrigerator for up to 3 days. Reheat the au jus gently on the stove before adding the beef to warm through. Assemble sandwiches just before serving to keep the bread from becoming soggy.

FAQs

Can I make the au jus ahead of time?

Yes, you can prepare the au jus a day ahead and reheat it before serving. It often tastes better as the flavors develop overnight.

What type of bread works best for French Dip Sandwiches?

Traditional French rolls or baguettes are ideal due to their crusty exterior and soft interior, which hold up well when dipped in au jus without getting soggy too quickly.
