Ingredients
  

  • 3.5 lbs beef chuck roast
  • 2 large yellow onions, thinly sliced
  • 2 packets (1 oz each) dry onion soup mix
  • 1 can (10.5 oz) condensed French onion soup
  • 1 cup low -sodium beef broth
  • 3 cloves garlic , minced
  • 2 tablespoons unsalted butter
  • 1 teaspoon dried thyme
  • 0.5 teaspoon cracked black pepper
  • 0.25 teaspoon kosher salt

Instructions
 

  • Pat the beef chuck roast dry with paper towels and season surfaces with salt and black pepper.
  • In a large skillet over medium-high heat, melt the butter and sear the roast on all sides until a deep brown crust forms, approximately 4 minutes per side.
  • Place the sliced yellow onions in an even layer at the bottom of the slow cooker crock.
  • Transfer the seared beef roast into the slow cooker, resting it on top of the onions.
  • In a separate bowl, whisk together the beef broth, condensed French onion soup, dry onion soup mix, minced garlic, and thyme until combined.
  • Pour the liquid mixture over the beef in the slow cooker.
  • Cover with the lid and cook on the 'Low' setting for 8 to 10 hours (or 'High' for 5 to 6 hours) until the internal temperature reaches 202°F (94°C) and the meat is fork-tender.
  • Remove the roast from the cooker and allow it to rest for 10 minutes before shredding or slicing.
  • Skim excess fat from the cooking liquid and serve the remaining onion gravy over the meat.
