Ingredients
For the Salisbury Steaks
- 1 ½ lbs ground beef
- ½ cup breadcrumbs
- 1 large egg
- 2 tablespoons milk
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon dried parsley
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 tablespoon olive oil, for browning
For the Onion Gravy
- 2 large yellow onions, thinly sliced

- 1 teaspoon garlic powder
- 1 tablespoon cornstarch

How to Make Slow Cooker Salisbury Steak
Step 1: Prepare the Beef Mixture
In a large bowl, combine the ground beef, breadcrumbs, egg, milk, Worcestershire sauce, garlic powder, onion powder, parsley, salt, and black pepper.
Mix gently until everything is just combined. I usually try not to overmix the beef because that can make the patties tougher.
Step 2: Shape the Patties
Divide the mixture into about 6 equal portions and shape each one into an oval-shaped patty, similar to a small steak.
Try to keep the patties fairly even in thickness so they cook at the same rate.
Step 3: Brown the Patties
Heat the olive oil in a large skillet over medium-high heat.
Add the beef patties and brown them for about 2–3 minutes per side. They don’t need to be completely cooked at this point—the slow cooker will finish them.
I honestly recommend not skipping this step. Browning adds so much extra flavor to the finished gravy.
Step 4: Add the Onions
Place the sliced onions in the bottom of your slow cooker.
Arrange the browned Salisbury steak patties over the onions.
Step 5: Make the Gravy
In a bowl, whisk together the beef broth, Worcestershire sauce, ketchup, Dijon mustard, and garlic powder.
Pour the mixture over the beef patties and onions.
Step 6: Slow Cook
Cover and cook on:
- LOW for 5–6 hours, or
- HIGH for 2½–3½ hours
The beef should be tender and cooked through, while the onions should be soft and flavorful.
Step 7: Thicken the Gravy
About 15–20 minutes before serving, mix the cornstarch with cold water until smooth.
Stir the slurry into the gravy in the slow cooker.
Cover again and cook on HIGH for about 15–20 minutes, or until the gravy thickens.
Taste and adjust the salt and pepper if needed.
Step 8: Serve
Carefully spoon the tender Salisbury steaks onto plates and generously pour the onion gravy over the top.
Serve immediately with your favorite side dishes.
Cooking Tips
- Don’t overmix the beef. Gently combine the ingredients for softer, more tender patties.
- Brown the patties first. It adds a deeper, richer flavor to the entire dish.
- Slice the onions thinly. Thin slices become wonderfully soft during slow cooking.
- Use low-sodium beef broth if you want more control over the saltiness.
- Add the cornstarch slurry at the end. This gives you a smooth, thick gravy without making it overly heavy.
- If the gravy gets thicker than you like, simply stir in a splash of warm beef broth before serving.

And yes, I highly recommend having some crusty bread nearby. You won’t want to waste that gravy!

Frequently Asked Questions
1. Can I make Salisbury steak without browning the patties first?
Yes. You can place the uncooked patties directly into the slow cooker, but browning them first gives the beef a much richer flavor and better color.
2. Can I use frozen ground beef patties?
For the best results, use thawed ground beef so you can mix and season the patties properly. If using prepared frozen patties, cooking times may vary, so make sure the beef reaches a safe internal temperature.
3. How do I store leftover Salisbury steak?
Allow the leftovers to cool, then place them in an airtight container and refrigerate for up to 3–4 days. Store the beef and gravy together so the patties stay moist.
4. Can I freeze Salisbury steak?
Absolutely. Let the cooked Salisbury steak cool completely, then freeze it with the gravy in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
5. How can I make the gravy thicker?
The easiest method is to combine 1 tablespoon cornstarch with 2 tablespoons cold water, then stir it into the gravy near the end of cooking. Let it cook for another 15–20 minutes until thickened.
