Slow Cooker French Dip Sandwiches with Garlic & Mushrooms are savory, juicy sandwiches made with tender shredded beef slow-cooked in a rich broth with mushrooms, garlic, and herbs. Served on toasted rolls with optional melted cheese and warm au jus for dipping, they’re the ultimate comfort food with minimal effort.

Ingredients

  • 34 lb chuck roast or beef shoulder
  • 4 garlic cloves, minced
  • 8 oz mushrooms, sliced
  • 1 onion, sliced (optional)
  • 4 cups beef broth
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon soy sauce or tamari
  • 1 teaspoon dried thyme
  • Salt and black pepper, to taste
  • 6 sandwich rolls or hoagie buns
  • 6 slices provolone or mozzarella cheese (optional)
  • Butter or olive oil, for toasting rolls

Instructions

  1. Season chuck roast with salt and pepper and place in slow cooker.
  2. Add mushrooms, garlic, and optional onion on top of the beef.
  3. Pour in beef broth, Worcestershire sauce, and soy sauce. Sprinkle thyme over everything.
  4. Cover and cook on low for 8 hours or high for 4–5 hours, until beef is fork-tender.
  5. Remove beef, shred with two forks, and return to slow cooker to soak in juices.
  6. Toast sandwich rolls with butter or oil in a skillet or oven until golden.
  7. Pile shredded beef and mushrooms onto rolls. Top with cheese if using and broil until cheese melts.
  8. Serve each sandwich with a small bowl of the cooking broth (au jus) for dipping.

Notes

  • Add a splash of red wine to the broth for deeper flavor.
  • Use Swiss cheese or horseradish mayo for variation.
  • Skip the bread and serve over sautéed greens or cauliflower mash for a low-carb version.
  • Store leftover beef and broth separately and reheat gently for best texture.
