Slow Cooker Ground Beef French Dip Sandwiches turn two pounds of browned beef and one sliced onion into six rich, cheesy sandwiches with savory cooking liquid for dipping. Quick-cooking oats thicken the mixture gently while beef broth, onion soup mix, Worcestershire, garlic, and pepper build familiar French-dip flavor.
The recipe makes exactly 6 sandwiches in 4 hours 15 minutes, including 15 minutes of preparation and up to 4 hours of slow cooking. Provolone is added only for the last 15–20 minutes so it melts across the beef without disappearing into the liquid.
Ground Beef French Dip Ingredients
For the beef mixture, gather 2 pounds lean ground beef, 1 large yellow onion thinly sliced, and ½ cup quick-cooking oats. The liquid and seasonings are 1⅓ cups beef broth, one 1-ounce envelope beefy onion soup mix, 1 tablespoon Worcestershire sauce, ½ teaspoon garlic powder, and ½ teaspoon freshly ground black pepper.
For assembly, use exactly 6 provolone slices and 6 brioche burger buns or slider rolls. One cheese slice and one bun are allotted to every sandwich.
