🥩 Ingredients
1½ pounds ground beef, preferably 80–90% lean
1 teaspoon kosher salt
½ teaspoon black pepper
2 large yellow onions, thinly sliced
1 can (10.5 ounces) condensed French onion soup
1 packet (1 ounce) dry onion soup mix
👩🍳 Instructions
- Prepare the Beef
Divide the ground beef into portions and shape each portion into a thick burger steak. Keep the patties firm but avoid overworking the meat.
- Arrange in the Slow Cooker
Place the beef patties in a single layer inside the slow cooker, leaving a little space between them when possible.
- Season the Beef
Sprinkle the kosher salt and black pepper evenly over the burger steaks.
- Add the Onions
Spread the sliced yellow onions over and around the beef patties. The onions will soften during cooking and add wonderful sweetness to the gravy.
- Add the French Onion Soup
Pour the condensed French onion soup evenly over the beef and onions.
- Add the Onion Soup Mix
Sprinkle the dry onion soup mix evenly over the top.
- Slow Cook
Cover the slow cooker and cook on LOW for approximately 5–6 hours, or until the beef reaches a safe internal temperature and is tender.
- Serve
Carefully spoon the tender burger steaks onto plates and generously top them with the softened onions and rich French onion gravy.

💡 Recipe Tips
Don’t overwork the beef: Gently shape the patties so they remain tender after slow cooking.
Slice the onions evenly: Thin, consistent slices cook more evenly and become soft and flavorful.
Keep the lid closed: Try not to repeatedly open the slow cooker during cooking because heat escapes and can extend the cooking time.
Check the beef: Cooking time can vary depending on the size and thickness of the patties and your slow cooker. Use an instant-read thermometer to confirm the beef has reached a safe temperature.
