Ingredients
  

Roast & Vegetables
  • 3-4 lbs beef chuck roast boneless
  • 3 large yellow onions sliced into half moons
  • 4 cloves garlic minced
Sauce
  • 2 cups beef broth low sodium
  • 1 packet French onion soup mix
  • 2 tbsp Worcestershire sauce
  • 1 tbsp balsamic vinegar
  • 4 tbsp unsalted butter sliced
  • 1 tsp dried thyme
Topping
  • 6-8 slices Provolone cheese
  • 1 tbsp fresh parsley chopped, for garnish

Equipment

  • Slow Cooker (6qt or larger)
  • Cutting board
  • Chef's Knife
  • Measuring Cups

Method
 

  1. Slice the onions into thick half-moons. Place half of the onions at the bottom of the slow cooker.
  2. Pat the chuck roast dry with paper towels and season generously with black pepper. Place the roast on top of the onions.
  3. Sprinkle the French onion soup mix, minced garlic, and dried thyme over the roast. Top with the remaining sliced onions.
  4. In a mixing bowl or measuring cup, whisk together beef broth, Worcestershire sauce, and balsamic vinegar. Pour this mixture around the roast.
  5. Place butter slices directly on top of the meat.
  6. Cover and cook on LOW for 8-9 hours or on HIGH for 4-5 hours, until the meat is very tender and shreds easily.
  7. Once cooked, shred the beef slightly if desired. Arrange Provolone cheese slices over the top of the meat and onions.
  8. Cover and let sit for 10-15 minutes until cheese is fully melted and bubbly. Garnish with fresh parsley and serve warm.
