Instructions
Prepare the beef
Pat the beef chuck roast dry with paper towels. Season with salt and pepper.
Pro tip: Drying the beef helps achieve a better sear.
Sear the beef
Heat vegetable oil in a large skillet over medium-high heat. Sear the beef on all sides until browned, about 4 minutes per side.
Pro tip: Searing locks in the juices and adds depth of flavour.
Prepare the slow cooker
Place sliced onions and minced garlic in the bottom of a slow cooker. Transfer the seared beef on top.
Pro tip: Layering the onions and garlic first ensures even cooking.
Add liquids
Pour beef broth, Worcestershire sauce, and soy sauce over the beef. Ensure the beef is mostly submerged.
Pro tip: Adjust the seasoning if needed after tasting the broth.
Slow cook the beef
Cover and cook on low for 8 hours or until the beef is tender and shreds easily with a fork.
Pro tip: Check the tenderness by inserting a fork in the thickest part of the beef.
Shred and serve
Remove the beef from the slow cooker, shred using two forks, and return it to the juices. Serve on kaiser buns.
Pro tip: For extra flavour, mix some of the cooking juices with the shredded beef before serving.
Tips & Tricks
- Select a well-marbled beef chuck for the most tender result.
- For a deeper flavour, sear the beef before slow cooking.
- Keep the buns warm in aluminum foil for softer bites.
- Use a meat thermometer to ensure beef is perfectly tender.
