How to Make Crockpot French Dip Sandwiches: Step by Step
This Crockpot French Dip Sandwich Recipe comes together with a hands-off approach, letting flavors meld as you tackle your day. Here’s how you pull it all together:- Generously season the beef roast with salt and pepper, making sure every side gets a good coating for deep, even flavor in every bite.
- Mix the beef broth and Worcestershire sauce in a large measuring cup or bowl and set aside to let those flavors combine.
- In a large skillet, Dutch oven, or right in your Instant Pot on sauté mode, heat olive oil until shimmering. Place your seasoned beef in the pan and sear it on all sides until browned, forming a crisp, flavorful crust. Transfer the beef to your slow cooker (or remove from the Instant Pot for now).
- Lower the heat and add sliced onions to the skillet you used for the beef. Stir and cook until golden and softened. Toss in minced garlic and cook until fragrant. Deglaze with a splash of broth mixture, scraping up deep brown bits stuck to the pan—pure flavor for the final au jus.
- Spoon the onion and garlic mixture, along with those tasty juices, into the slow cooker (or back into the Instant Pot). Add the remaining broth mixture and bay leaf, nestling everything around the beef.
- For slow cooker: Cover and cook until the beef is fall-apart tender. For Instant Pot: Secure the lid and cook on high pressure until the beef easily shreds with a fork, then naturally release the pressure.
- Remove beef to a cutting board. Slice thinly against the grain or shred. Strain the cooking liquid through a fine mesh strainer into a bowl—this is your golden, savory au jus. Discard the bay leaf, and reserve the onions.
- Return sliced or shredded beef and reserved onions to the cooker. Add a splash of au jus to keep everything moist and juicy. Taste and adjust salt and pepper as needed.
- Lightly toast sturdy rolls until crisp around the edges. Pile on the hot meat and onions, then lay over slices of melty cheese. Pop sandwiches into a hot oven or under the broiler until the cheese bubbles and the rolls are golden.
- Ladle au jus into small bowls and serve alongside the sandwiches for classic dipping action—every dunk brings up all the deep beefy goodness.
Texture Tips and Common Pitfalls
A killer French dip sandwich is all about texture—the juicy, tender beef; the chewy, toasted roll; the stringy, molten cheese holding it all together. Watch out for a few classic missteps and you’ll be dunking sandwiches like a pro.- Don’t skip the sear: Searing the beef before slow cooking adds a deep, roasted flavor and an irresistible edge to your meat.
- Get the onions soft and golden: Give onions time to fully soften and caramelize—they’ll melt seamlessly into every bite.
- Use sturdy bread: Soft sandwich rolls will fall apart in the au jus. Pick something that can handle a good soak without turning mushy.
- Trim the fat after cooking: If there’s excess fat on your roast, you can easily remove it once the meat is cooked and cooled just a bit.
- Broil cheese with care: Keep a close eye so you get melted, bubbling cheese without burning the top.
If the beef seems dry, splash in a little extra au jus before piling onto your rolls. If your au jus seems thin, let it simmer a few extra minutes to concentrate the flavor.
Serving Ideas and Variations for Your French Dip Sandwich
Crockpot French Dip Sandwiches are a comfort classic all on their own, but you can make them your own with simple twists. Serve them as the star at a casual dinner party, or as a cozy weekend family meal.Swapping the cheese can give every sandwich a new personality—provolone is traditional, but havarti or Swiss change up the vibe. Add sautéed mushrooms or roasted bell peppers to the beef and onions for an extra veg-forward touch.
On the side, go for oven fries, simple green salads, or creamy coleslaw. For a lighter option, a cup of broth-based soup fits right in. These sandwiches also make crowd-pleasing party sliders if you use smaller rolls—game night, anyone?
Storing and Reheating Crockpot French Dip Sandwiches
Got leftovers? Store the cooked beef and onions, covered, in the fridge—just be sure to keep the au jus separate so nothing gets soggy before you’re ready to eat.To reheat, simply warm the beef and onions gently on the stove or in the microwave, stirring in a splash of reserved au jus to keep things juicy. Toast the rolls separately and assemble fresh for best texture. Extra au jus can be reheated in a saucepan until steaming.
While French dip beef can freeze well, it’s best to store just the meat and onions (without the bread or cheese) in freezer-safe containers. Thaw overnight in the fridge before reheating and serving as sandwiches again.

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.
