The French dip sandwich is a hot beef sandwich consisting of tender thin slices of beef layered a long white French roll that is dipped into a flavorful sauce made from the pan juices. It is a staple at any diner in America. My recipe is a mash-up between French Onion Soup and the French Dip Sandwich. Caramelized onions are piled along with the beef and cheese on a crusty roll.

Units Scale
  • 2 1/2 pounds beef chuck steaks, trimmed of excess fat*
  • 1/2 tsp kosher salt
  • 1/4 tsp pepper
  • 3 cups beef broth (or 3 cups water and 3 tsp of Better Than Bouillon Beef Base)
  • 1/4 cup worcestershire sauce
  • 2 large yellow onions, very thinly sliced
  • 2 tsp garlic powder
  • 1 bay leaf
  • 8 large crusty rolls, toasted if you prefer
  • 8 slices provolone, Gruyere or Swiss cheese


  1. Place beef** in the slow cooker. Salt and pepper the beef.
  2. Add broth, worcestershire, onions***, garlic powder and bay leaf to slow cooker.
  3. Cover and cook on low for 8 hours, or until beef is very tender.
  4. Remove the beef and place it on a cutting board. Slice or shred the meat.
  5. Place a fine mesh strainer over a large bowl and pour the juice from the slow cooker through the strainer and into the bowl. This juice will be your au jus, dipping sauce. The onions, in the strainer will be used on top of your sandwiches. Discard the bay leaf.
  6. Add meat back into the slow cooker. Salt and pepper to taste.
  7. Pile meat on top of rolls and use tongs to place onions on top of meat. Place a slice of cheese on top of the onions. If desired, place the roll with meat and cheese under the broiler so the cheese will melt. Serve sandwiches with a side of the reserved au jus.


*You can also use beef chuck roast in place of the chuck steaks. Just quarter the roast before adding it to the slow cooker.

**For a more developed, meaty flavor you can brown the roast before adding it to the slow cooker. In a large skillet, heat 2 tablespoons of olive oil on medium-high heat, add the meat and sear on all sides until each side has a brown crust.

***If you want a more developed flavor, caramelize the onions on the stovetop before adding them to the slow cooker. Coat the bottom of the pan with olive oil. Heat the pan on medium high heat. Add the onion slices and stir to coat the onions with the oil. Spread the onions out evenly over the pan and let cook, stirring occasionally. The onions will develop a brown color.

****I used my 6 quart KitchenAid Slow Cooker for this recipe.
