Prep Time: 15 minutes
Cook Time: 8–10 hours
Servings: 6–8
🛒 Ingredients
- 3–4 lbs boneless beef chuck roast or beef brisket
- 1 large yellow onion, thinly sliced
- 4 cloves garlic, minced

👩🍳 Instructions
- Sear the beef: Season the roast generously with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear the beef for 3–4 minutes per side, until deeply browned. Transfer to the slow cooker.
- Make the sauce: Whisk together balsamic vinegar, beef broth, soy sauce, brown sugar, Worcestershire sauce, garlic, and thyme.
- Layer: Place sliced onions over the beef. Pour the balsamic mixture over everything and add the bay leaf.
- Slow cook: Cover and cook on LOW for 8–10 hours or HIGH for 4–5 hours, until the beef is tender and easily pulls apart with a fork.
- Serve: Remove the bay leaf. Shred or slice the beef and spoon the balsamic onions and flavorful juices over the top.
