Step-by-Step: How to Make Crockpot French Dip Sandwiches
Transform a humble roast into a crowd-pleasing dinner with these foolproof steps. Each moment brings you closer to tender beef, golden onions, and that irresistible au jus.- Season the beef roast generously with salt and pepper, making sure every surface is well-coated.
- In a large measuring cup, whisk together the beef broth and Worcestershire sauce, then set that aside—it’ll be your braising base and dipping jus.
- Heat a cast iron skillet, Dutch oven, or your Instant Pot on sauté mode with olive oil. Sear the seasoned roast on all sides until each has a dark, rich crust. Move the beef into your slow cooker.
- Lower the heat and use the same pan to cook the sliced onions, letting them soften and turn golden. Stir in the garlic and cook until fragrant. Splash in a little of the broth mixture, scraping up all those flavorful browned bits.
- Transfer the onion-garlic mixture and all those tasty juices to your slow cooker with the beef. Pour in the rest of the broth mixture and add the bay leaf if you’re using one.
- Let the slow cooker work its magic until the beef is meltingly tender and can be easily sliced or shredded. Remove the beef, slice or shred, and set aside.
- Place a fine mesh strainer over a large bowl, then strain out the beefy juices (this is your au jus). Save the onions and discard the bay leaf.
- Return the beef and onions to the slow cooker, add a bit of au jus to keep things juicy, and adjust seasoning if needed.
- Toast your rolls until they’re crisp and golden outside. Pile on the beef and onions, top with slices of your favorite cheese, and melt under a hot oven or broiler until bubbly and gooey.
- Serve straight away with a bowl of warm au jus on the side for dunking each bite—don’t be shy with the dip!
Texture Tips and Tricks for Perfection
The real key to a dreamy French dip comes down to tender beef, soft-but-not-mushy onions, and rolls sturdy enough for serious dunking. Keep these tips in mind as you cook:- Always sear the beef—this locks in juices and builds that crave-worthy flavor into every strand.
- Slice or shred the beef against the grain for the softest, easiest-to-chew bite.
- Don’t skip caramelizing the onions—give them time to sweeten and brown for extra depth.
- If your au jus tastes too salty, you can dilute it with a splash of extra beef broth.
- Toast rolls before filling to help them stand up to the hot, steamy broth and keep sandwiches from falling apart.
Creative Variations and What to Serve with French Dip
One of the best things about the Crockpot French Dip Sandwich Recipe is how easy it is to shake up with your own favorite twists. Swap the cheese up—try extra gooey havarti, nutty swiss, or even a layer of sharp cheddar for a modern spin. Sometimes I add a swipe of horseradish cream or Dijon mustard on the bottom bun for a peppery kick.Pairings are just as fun—classic French dip sandwiches beg for a simple green salad or a side of crispy oven fries. For something heartier, a creamy potato soup or roasted vegetables work wonderfully. And if you’re serving a crowd, keep the au jus hot and let everyone dip as they please!
Storing and Reheating French Dip Sandwiches
Leftover beef and au jus keep well when stored separately in airtight containers in the refrigerator. Reheat the meat gently in some of the reserved au jus to keep everything juicy—this stops the beef from drying out. Rolls are best toasted fresh, but you can give them a quick warm-up in the oven if needed.If you want, you can freeze extra cooked beef and au jus for future cravings. Just thaw in the fridge overnight and heat slowly. Add fresh rolls and cheese for sandwiches that taste just as comforting as day one.

Slow Cooker French Dip Sandwiches
Ingredients
Equipment
Method
- Liberally salt and pepper your roast.
- In a large glass measuring cup, combine the beef broth and Worcestershire sauce and set aside.
- In a large cast iron skillet, Dutch oven, or in your Instant Pot in sauté mode, heat oil on medium-high heat, add the meat and sear on all sides until each side has a nice brown crust formed. Transfer meat into your slow cooker (if using) OR remove the meat from your Instant Pot and continue.
- Reduce the heat to medium, and in the same pot you browned the meat in, add the sliced onions and cook for 5 minutes, adding more oil if necessary. Add the chopped garlic and cook for an additional minute or two. Pour a couple tablespoons of the beef broth mixture into the pot with the onions and using a wooden spoon, scrape up all the browned bits from the bottom of the pan (this will add lots of flavor).
- Transfer the onion mixture and all accumulated juices into the slow cooker (with the meat) and add in the remaining broth and the bay leaf. Cook in your slow cooker on high for 3-4 hours or low for 5-6 hours, until the meat is very tender. Remove the meat to a cutting board and thinly slice it (against the grain) or shred it, set aside.
- Place a fine mesh strainer over a large bowl and carefully pour the juices from the slow cooker through the strainer and into the bowl (this is your au jus). Set aside the onions that remain in the strainer, discard the bay leaf.
- Transfer the sliced meat and the onions back into the slow cooker. Pour over a little bit of au jus to moisten the meat and season to taste with salt and pepper. Reserve the remaining au jus for dipping. If you'd like more au jus, you can stir in a little beef broth to make it stretch farther.
- Toast your rolls, fill with meat and onions, cover with the cheese of your choice. Melt the cheese in a 375° oven or under the broiler until melted. Serve with the au jus on the side for dipping.
