Before you start
Before you begin, ensure your slow cooker is clean and ready for use. Take the beef roast out of the refrigerator about 30 minutes before you plan to start seasoning it; this helps the meat cook more evenly.
Make sure you have your spices measured and ready, and that your onions are sliced into uniform, thin slices to ensure they cook down properly.
Preparing your workspace by clearing a clean surface for seasoning the meat will make the assembly process much smoother and keep your kitchen organized throughout the preparation.
Ingredients at a glance (10)
- 3 lb beef rump roast
- 2 tbsp smoked paprika
- 1 tbsp garlic powder
- 1 tbsp dried oregano
- 1 large white onion, thinly sliced
- 60 ml apple cider vinegar
- 1 stick unsalted butter
- 6 kaiser rolls, toasted
- 1/2 cup creamy horseradish sauce
- 1 medium red onion, sliced into rings
Instructions
Seasoning and Layering
- Season the beefCombine the smoked paprika, garlic powder, and dried oregano in a small bowl. Rub the seasoning mixture thoroughly over the entire surface of the beef rump roast to create a flavorful crust.Look for The beef should be evenly coated with the spice mixture on all sides.Tip Pat the beef dry with paper towels before seasoning to ensure the spices stick well to the meat.
- Layer the slow cookerPlace the thinly sliced white onion at the bottom of the slow cooker insert. Place the seasoned beef roast on top of the onions. Pour the apple cider vinegar around the sides and place the stick of butter directly on top of the beef.Look for Ensure the onions are distributed evenly to act as a bed for the roast.Tip Layering the onions underneath prevents the beef from sticking and adds flavor to the cooking juices.
The beef should be thoroughly coated in the spice rub, and the onions should be spread evenly to provide a aromatic bed for the roast. Everything should be arranged in the slow cooker with the butter placed on top, ready for the long, slow transition into a tender, flavorful meal.
Slow Cooking and Shredding
- Slow cook and shredCover the slow cooker and cook on the LOW setting for 7.5 hours. Ensure the beef reaches an internal temperature of 145°F (63°C). Let the meat rest for at least 3 minutes before using two forks to shred the tender meat directly in the pot, mixing it with the bubbling mahogany jus.Look for The beef should be incredibly tender and pull apart easily with minimal effort.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Allow the shredded meat to soak in the juices for a few minutes before serving to maximize flavor absorption.
The beef is finished when the meat is extremely tender and easily shreds with two forks. The cooking liquid should be a deep, rich mahogany color, indicating that the flavors of the spices and the meat have melded perfectly into a savory, smoky jus.
Final Assembly
- Assemble the sandwichesToast the kaiser rolls until golden brown. Spread a generous amount of creamy horseradish sauce on both sides of the rolls. Pile the shredded smoky beef onto the bottom halves, top with raw onion rings, and close the sandwiches to serve.Look for The rolls should be crisp and the horseradish sauce should coat the meat evenly.Tip Let the roast rest for at least 3 minutes after shredding to ensure the juices redistribute throughout the meat.
The sandwiches are ready when the rolls are toasted, the beef is hot and well-coated in its juices, and the horseradish sauce provides a creamy, sharp contrast. Ensure the raw onion rings are crisp and fresh to provide a final textural element to the finished sandwich.
Common mistakes
A common mistake is rushing the cooking process; do not be tempted to increase the heat to speed things up, as this will result in tough, dry meat. Another error is failing to toast the rolls, which can lead to a soggy sandwich that loses its structural integrity quickly.
Additionally, avoid overcrowding the slow cooker with too many extra vegetables or liquids, as this will dilute the concentrated smoky flavor of the jus. Finally, always ensure the beef is fully shredded before serving to guarantee the best texture.
How to tell it’s done
The beef is perfectly done when it reaches an internal temperature of 145°F (63°C). At this point, the meat should be incredibly tender and yield easily when pressed with a fork. It will have a dark, mahogany color from the spice rub and the cooking juices.
Let the meat rest for at least 3 minutes after shredding to allow the juices to settle, which ensures each bite is as moist as possible. The texture should be soft and pull-apart, with no resistance when you shred it.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
