This 5-ingredient slow cooker French dip is the kind of recipe I lean on during busy work weeks: you literally put a raw beef rump roast into the slow cooker, add four simple ingredients, and walk away. Hours later, you’ve got tender, shredded beef and a rich, savory jus that tastes like you fussed over it all day. French dip sandwiches are believed to have started in early 1900s Los Angeles, but this version is pure Midwestern practicality—minimal effort, big payoff, and perfect for feeding friends who will absolutely ask how you made it.
Pile the juicy shredded beef onto toasted hoagie rolls or French rolls, then ladle the hot cooking liquid into small bowls for dipping. Add a slice of provolone or Swiss and broil the sandwiches for a minute if you like them melty. I love serving these with a simple green salad, roasted frozen veggies, or oven fries for an easy weeknight dinner. For game days or casual get-togethers, set out a slow cooker full of beef, a tray of rolls, and bowls of the au jus so everyone can build their own sandwich.
5-Ingredient Slow Cooker French Dip (Rump Roast)Servings: 8
Ingredients
3 to 4 pound raw beef rump roast, trimmed of excess surface fat
2 cups low-sodium beef broth
1 (1-ounce) packet dry onion soup mix
2 tablespoons Worcestershire sauce
1 teaspoon garlic powder
Directions
Place the raw beef rump roast in the bottom of a large slow cooker so it sits flat in a single piece.
Sprinkle the dry onion soup mix and garlic powder evenly over the top and sides of the roast.
Pour the beef broth and Worcestershire sauce around the roast in the slow cooker, trying not to rinse off too much of the seasoning on top.
Cover and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the roast is very tender and easily shreds with a fork.
Transfer the cooked roast to a large cutting board or shallow dish. Use two forks to shred the beef into bite-sized pieces, discarding any large pieces of fat.
Skim excess fat from the surface of the cooking liquid in the slow cooker with a spoon. Return the shredded beef to the slow cooker, stir to coat in the juices, and let it sit on WARM for at least 15 minutes so it can soak up more flavor.
Taste the beef and jus, and add a pinch of salt and black pepper if needed. Serve the shredded beef on toasted rolls with small bowls of the hot cooking liquid on the side for dipping.
Variations & Tips
For a little extra richness, you can substitute 1/2 cup of the beef broth with dry red wine, keeping the total liquid amount the same. If you like a stronger onion flavor, add 1 thinly sliced yellow onion on top of the roast before cooking. To make it cheesy, top the assembled sandwiches with provolone or Swiss and broil for 1 to 2 minutes until melted and bubbly. If you need this to be lower in sodium, choose reduced-sodium beef broth and look for a low-sodium onion soup mix, then taste before adding any extra salt. For a freezer-friendly meal, you can place the raw rump roast and all four additions into a large freezer bag, label it, and freeze flat; thaw in the fridge overnight, then dump into the slow cooker and cook as directed. Food safety tips: Always start with a fully thawed roast—do not put a frozen rump roast directly into the slow cooker, as it can stay too long in the temperature “danger zone.” Keep the lid on during cooking, and use a meat thermometer if you’re unsure; the internal temperature should reach at least 145°F, though you’ll typically be well above that for shreddable texture. Refrigerate leftovers within 2 hours of cooking, store in an airtight container with some of the jus, and use within 3 to 4 days, reheating until steaming hot before serving.
