How to Make French Dip Sandwiches
- Sear the Beef: Cut the roast into 4-5 chunks, season generously with salt and pepper, and sear in hot oil until browned on all sides, about 2-3 minutes. This step locks in those delightful flavors!
- Simmer the Broth: In the same pot, add chicken broth, white vinegar, celery, carrot, garlic, oregano, thyme, whole peppercorns, and bay leaves. Bring to a gentle simmer, cover, and cook on low for 2-2.5 hours, until the beef is fork-tender and melt-in-your-mouth delicious.
- Reserve and Shred Beef: Carefully remove the beef from the pot, strain out the vegetables from the broth, and shred the beef with two forks, discarding any excess fat. You’ll want luscious, tender shreds for your sandwich!
- Make Au Jus: In a separate saucepan, combine the reserved beef stock with au jus seasoning and water. Bring to a boil and let it bubble for 5 minutes. This rich dipping sauce is a game-changer!
- Prepare Horseradish Mayo: In a bowl, mix together mayonnaise, horseradish, lemon juice, chopped parsley, and garlic powder. Give it a good stir and chill until you’re ready to serve. This creamy concoction adds a scrumptious zing!
- Prepare Onion Rings and Buns: Cook the onion rings according to package instructions. While they’re cooking, toast the ciabatta buns under the broiler until golden brown for that perfect crust.
- Assemble Sandwiches: In a frying pan, heat a cup of au jus until it’s hot. Add in the shredded beef, allowing it to soak up the flavors. Spread a layer of horseradish mayo on the toasted buns, layer on the beef, top with crispy onion rings and roasted red peppers, and serve with the warm au jus for dipping. Enjoy!
Optional: Garnish with fresh parsley for a pop of color on your sandwiches.

• Chill the Mayo: Allow the horseradish mayo to chill for at least half an hour; this melds the flavors beautifully and makes each bite more enjoyable.
• Serve Promptly: Assemble and serve the sandwiches right away to prevent the buns from becoming soggy from the beef and au jus.

French Dip Sandwiches Recipe FAQs
How do I know if my beef is fresh enough for cooking?
Absolutely! When selecting beef, look for bright red coloring without dark spots or excessive marbling. The meat should smell fresh, with no off odors. If you’re buying chuck roast, choose one with a good fat-to-meat ratio, as the fat helps keep the meat tender and flavorful during cooking.
What is the best way to store leftover French Dip Sandwiches?
I often wrap any leftover assembled sandwiches tightly in foil and keep them in an airtight container in the fridge. They’ll last up to 3 days. When you’re ready to enjoy them, gently reheat to ensure the bun stays crispy and the beef remains juicy!
Can I freeze the beef and au jus? How?
Yes! You can absolutely freeze the shredded beef and au jus separately for up to 3 months. Once completely cool, place the beef in an airtight container or freezer bag. For the au jus, let it cool before pouring into a suitable container. When ready to enjoy, thaw overnight in the fridge and reheat over low heat on the stove before assembling your delicious French Dip Sandwiches.
What should I do if my au jus turns out gritty?
Very! If you experience grittiness in your au jus, it likely comes from not straining the broth well enough. Next time, ensure you strain the vegetables thoroughly using a fine mesh sieve. Additionally, you can blend the broth and then strain it again for a smoother consistency.
Are French Dip Sandwiches suitable for my gluten-sensitive friend?
Absolutely! If you have guests with gluten sensitivities, consider using gluten-free buns or lettuce wraps as an alternative to ciabatta. Also, double-check your broth and seasonings to ensure they are gluten-free. It’s a delicious way for everyone to enjoy this comforting meal together!
Can I substitute the horseradish in the mayo?
Yes! If horseradish isn’t to your liking or you need a milder option, you can use Dijon mustard or even a spicy aioli as a replacement in the mayo. This switch will provide a different but equally pleasing flavor that still complements the juicy beef.
