Equipment

7 - quart slow cooker

Ingredients

4 cups low sodium beef stock
2 teaspoons Worcestershire sauce
1/2 teaspoon salt
½ teaspoon pepper
2.2 ounces Beefy Onion Soup Mix 2 envelopes
1 large onion
3 cloves garlic
4 pounds rump roast
8 sub rolls
1 stick butter softened
2 Tablespoons garlic powder
16 slices provolone cheese

Instructions

Pour the beef stock, Worcestershire sauce, salt, pepper, and onion soup mix into the bottom of the slow cooker. Stir to combine.
4 cups low sodium beef stock, 2 teaspoons Worcestershire sauce, 1/2 teaspoon salt, ½ teaspoon pepper, 2.2 ounces Beefy Onion Soup Mix
Thinly slice the onion and mince the garlic. Add both to the slow cooker.
1 large onion, 3 cloves garlic
Place the rump roast in the slow cooker. Cook on low for 8 hours.
4 pounds rump roast
Once the meat is fully cooked, turn the slow cooker to warm. Remove the meat, thinly slice it, and return it to the broth until ready to serve.
Preheat the oven to broil and adjust the rack to the top third of the oven.
Split and butter each roll. Sprinkle with garlic powder and top with 2 slices of provolone. Place on a baking sheet and broil until the bread is toasted and cheese is melted, about 3-4 minutes.
8 sub rolls, 1 stick butter, 2 Tablespoons garlic powder, 16 slices provolone cheese
Assemble the sandwiches by placing a generous portion of meat and onions on each roll.
Ladle a small cup of the au jus (broth) to serve alongside for dipping.

Notes

To substitute the beefy onion soup mix:

Regular onion soup mix can be used, though the beef flavor will be less intense. You can add one beef bouillon cube to boost the flavor, but be mindful of sodium levels. To make a homemade equivalent for 1 packet of beefy onion soup mix, combine: 1 1/2 tablespoons dried minced onion, 1 teaspoon onion powder, 1 1/2 teaspoons granulated garlic, 1/4 teaspoon pepper, and 3 beef bouillon cubes (crumbled).

Chuck roast may be used in place of rump roast, but it will shred rather than slice and has more fat. Be sure to skim fat from the broth before serving. This recipe can be cooked in the slow cooker on high for 4 hours but I don’t recommend it, the meat will come out a bit tough.
