How to Make Slow Cooker French Dip
1. Prepare the Beef
Start by trimming any excess fat from the rump roast. Removing some of the excess fat helps keep the cooking liquid from becoming overly greasy.
Place the roast directly into your slow cooker.
2. Add the Cooking Liquid
Pour the beer, condensed French onion soup, and beef broth over the roast.
These simple ingredients create a flavorful cooking liquid that will eventually become your dipping sauce.
3. Slow Cook
Cover the slow cooker and cook on Low for about 7 hours.
The long, slow cooking time allows the beef to become tender while absorbing the flavors of the onion soup, broth, and beer.
4. Warm the Bread
When the beef is nearly ready, preheat your oven to 350°F (175°C).
Split the French rolls and arrange them on a baking sheet. Spread the cut sides with butter.
Bake for approximately 10 minutes, or until the rolls are warmed through and lightly toasted.
5. Slice the Beef
Remove the cooked roast from the slow cooker.
Let it rest briefly, then slice it thinly across the grain. Thin slices make the sandwiches easier to eat and give you that classic French dip texture.
If you prefer shredded beef, you can also pull the meat apart instead.
6. Build the Sandwiches
Pile the tender beef onto the warm French rolls.
For a cheesy version, add sliced provolone or Swiss cheese and place the sandwiches under the broiler for a few moments until the cheese melts and becomes bubbly.
7. Serve With Au Jus
Pour some of the flavorful cooking liquid into small bowls for dipping.
Serve each sandwich with plenty of au jus on the side.
Dip, bite, and enjoy!
Tips for the Best French Dip Sandwiches
Slice the Beef Thinly
Thin slices give the sandwich its classic texture. For especially neat slices, allow the roast to rest for a few minutes before cutting.
Don’t Skip the Toasted Rolls
Buttering and warming the French rolls adds another layer of flavor and gives the bread enough structure to hold the juicy beef and dipping sauce.
Add Cheese
While cheese isn’t required, provolone is a fantastic addition. Place it over the beef and broil until melted.
Make the Au Jus More Flavorful
The cooking liquid can be served as-is, but you can also boost the flavor with a little Worcestershire sauce, garlic powder, black pepper, or sautéed onions.
Try Different Cuts of Beef
Rump roast works beautifully, but other beef roasts can also work well for slow-cooked sandwiches. Choose a cut that becomes tender with low-and-slow cooking.
Easy Variations
Cheesy French Dip
Pile the beef onto toasted rolls, add provolone cheese, and broil until melted.
French Dip With Mushrooms
Sauté sliced mushrooms and add them to the sandwich with the beef and cheese.
French Dip With Caramelized Onions
Slowly caramelize sliced onions in a skillet and layer them over the beef for a sweeter, richer sandwich.
Garlic Butter Rolls
Mix a little garlic powder into the softened butter before spreading it over the French rolls.
Shredded French Dip
Instead of slicing the beef, shred it with two forks and return it to some of the cooking juices before serving.
What to Serve With French Dip Sandwiches
These sandwiches are hearty enough to stand on their own, but they pair especially well with:
- French fries
- Potato wedges
- Crispy roasted potatoes
- Onion rings
- Coleslaw
- Green salad
- Roasted vegetables
- Pickles
And of course, extra au jus for dipping is always a good idea.
Storage and Reheating
Store leftover beef and cooking juices separately in airtight containers in the refrigerator.
When ready to eat, gently reheat the beef in some of the cooking liquid. This helps keep the meat moist and flavorful.
You can also freeze the cooked beef with some of the au jus for a convenient future meal.
