How to Make Slow Cooker French Onion Salisbury Steak

Step 1: Mix the beef mixture

In a large bowl, combine the ground beef, salt, black pepper, garlic powder, breadcrumbs, egg, and Worcestershire sauce. Use your hands or a spoon to gently mix everything together until just combined. Try not to overmix, as that can make the patties dense instead of tender.

Step 2: Form the patties

Shape the mixture into oval patties. You should end up with about four evenly sized pieces. Keeping them similar in size helps them cook evenly.

Step 3: Place patties in the slow cooker

Arrange the patties in the bottom of your slow cooker in a single layer if possible. A little overlap is fine, but try to keep them mostly spread out.

Step 4: Add the soup and seasoning

Pour the French onion soup over the patties, making sure they are well coated. Then sprinkle the dry soup mix evenly over the top. This is where that deep onion flavor really starts to build.

Step 5: Pour in the broth

Add the beef broth to the slow cooker. This helps create enough liquid for the gravy and ensures everything cooks evenly.

Step 6: Cook low and slow

Cover the slow cooker and cook on low for 5 to 6 hours. The patties will become tender and soak up all that rich flavor as they cook.

Step 7: Make the slurry

In a small bowl, whisk together the cornstarch and water until smooth. This mixture will help thicken the gravy.

Step 8: Thicken the gravy

Stir the slurry into the slow cooker. Cover again and cook for an additional 10 to 15 minutes until the gravy thickens to a smooth, glossy consistency.

Step 9: Add the cheese

Place a slice of provolone cheese on top of each patty. Cover the slow cooker and let it sit for about 5 minutes, just until the cheese melts into a creamy layer.

Substitutions

• Ground turkey: You can use ground turkey instead of beef for a lighter version, though the flavor will be a bit milder.
• Panko breadcrumbs: These can replace regular breadcrumbs for a slightly lighter texture.
• Chicken broth: Works in place of beef broth if that is what you have on hand, though the flavor will be less rich.

Variations

• Mushroom addition: Add sliced mushrooms to the slow cooker for extra depth and a more earthy flavor.
• Swiss cheese topping: Swap the provolone for Swiss cheese for a slightly sharper finish.
• Serve with noodles: Instead of mashed potatoes, try serving this over egg noodles for a different take.

Tips and Tricks

• Do not overmix: Keeping the beef mixture lightly mixed ensures tender patties instead of dense ones.
• Layer flavors: Using both canned soup and dry mix creates a deeper, more complex onion flavor.
• Thicken at the end: Adding the cornstarch slurry at the end keeps the gravy smooth and glossy.
• Check seasoning: Taste the gravy before serving and adjust salt if needed.
• Use low heat: Cooking on low helps the patties stay tender and juicy.

FAQs

Can I cook this on high instead of low?
