Ingredients

Scale
  • 3 to 4 pounds beef chuck roast, trimmed of excess fat
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons olive oil or vegetable oil
  • 4 large yellow onions, thinly sliced
  • 3 cloves garlic, minced
  • 4 cups beef broth, preferably low sodium
  • 1/4 cup dry white wine or sherry (optional)
  • 2 tablespoons Worcestershire sauce
  • 2 teaspoons fresh thyme leaves or 1 teaspoon dried thyme
  • 1 bay leaf
  • 1 tablespoon cornstarch mixed with 1 tablespoon cold water
  • Fresh parsley, chopped (optional garnish)
  • Crusty bread or mashed potatoes (optional for serving)

Instructions

  1. Pat the beef chuck roast dry with paper towels and season generously with salt and black pepper on all sides.
  2. Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Sear the roast for about 4-5 minutes on each side until a deep brown crust forms. Transfer the roast to the slow cooker.
  3. In the same skillet, reduce heat to medium. Add sliced onions and a pinch of salt. Stir occasionally and cook for 15-20 minutes until onions are golden brown and soft. Add minced garlic in the last 2 minutes and stir until fragrant.
  4. Pour in the white wine or sherry (if using) to deglaze the pan, simmer for 2-3 minutes to reduce slightly.
  5. Transfer the caramelized onion mixture over the roast in the slow cooker. Add beef broth, Worcestershire sauce, thyme, and bay leaf. Cover with lid.
  6. Cook on low for 8-9 hours or on high for 4-5 hours until the roast is fork-tender and onions are deeply flavorful.
  7. About 30 minutes before serving, remove the roast to a plate and cover loosely with foil. Discard the bay leaf. Mix cornstarch with cold water and stir into the slow cooker liquid to thicken. Cook on high for 20-30 minutes until gravy thickens.
  8. Slice or shred the roast against the grain, spoon the onion gravy on top, and garnish with fresh parsley if desired.

Notes

Browning the meat before slow cooking enhances flavor and texture. Caramelize onions slowly over medium heat for best sweetness and color. Use a meat thermometer to ensure roast reaches about 190°F for fork-tender texture. Adjust seasoning after cooking. If roast is not tender enough, cook longer on low. For gluten-free, use gluten-free Worcestershire sauce and cornstarch or arrowroot powder. Leftovers taste better the next day.
