Slow cooker Salisbury steak features tender, seasoned beef patties covered with rich mushroom-and-onion gravy. It provides old-fashioned comfort-food flavor with less hands-on cooking.
Browning the patties before slow cooking develops a savory crust and helps them retain their shape. The slow cooker then finishes them gently while creating plenty of gravy for mashed potatoes or egg noodles.
This satisfying dinner uses affordable ground beef and can be prepared several hours before serving.

Ingredient Notes
Ground beef: An 85–90% lean blend provides flavor while helping the patties remain moist.
Breadcrumbs: Breadcrumbs absorb moisture and help bind the patties.
Egg: One egg provides structure without making the meat mixture dense.
Mushrooms: Cremini mushrooms provide a deeper flavor, while white mushrooms are milder.
Beef broth: Low-sodium broth allows better control over the final seasoning.
Cornstarch: Add it near the end to thicken the cooking liquid into gravy.
How to Make Slow Cooker Salisbury Steak
Step 1: Make the Beef Mixture
Place the ground beef, breadcrumbs, egg, milk, Worcestershire sauce, onion powder, garlic powder, salt and pepper in a large bowl.
Mix gently until combined.
Avoid compacting or overworking the meat.
Step 2: Shape the Patties
Divide the mixture into six equal portions.
Shape each portion into an oval patty approximately ¾ inch thick.
Press a shallow indentation into the center of each patty to help it cook evenly.
Step 3: Brown the Patties
Heat the olive oil in a large skillet over medium-high heat.
Brown the patties in batches for approximately 2 minutes per side.
They do not need to cook completely.
Step 4: Prepare the Slow Cooker
Arrange the sliced onion and mushrooms across the bottom of a 6-quart slow cooker.
Place the browned patties over the vegetables, overlapping them slightly if necessary.
Step 5: Add the Gravy Mixture
Whisk together the beef broth, tomato paste, Worcestershire sauce, Dijon mustard, thyme and garlic powder.
Pour the mixture around and over the patties.
Step 6: Slow-Cook
Cover and cook:
- On low for 4–5 hours, or
- On high for 2–3 hours.
The patties must reach an internal temperature of at least 160°F.
Step 7: Thicken the Gravy
Carefully transfer the cooked patties to a plate and cover them loosely.
Mix the cornstarch and cold water until smooth.
Stir the slurry into the slow cooker. Cover and cook on high for 10–15 minutes, until the gravy thickens.
Step 8: Serve
Return the patties to the gravy.
Taste and adjust the salt and pepper.
Garnish with parsley and serve over mashed potatoes, rice or egg noodles.
Tips for Tender Salisbury Steak
Mix the Beef Gently
Overworking ground beef creates dense, firm patties.
Brown in Batches
Leave space between the patties to encourage browning rather than steaming.
Use Cold Water for the Slurry
Cornstarch mixed directly into hot liquid forms lumps.
Check the Patties Early
Slow cookers vary in temperature. Begin checking at the lower end of the time range.
Taste After Thickening
The gravy’s flavor becomes more concentrated as it thickens.
Recipe Variations

Creamy Mushroom Gravy

Gluten-Free Version
Use gluten-free breadcrumbs and verify that the Worcestershire sauce and broth are gluten-free.

Storage and Reheating
Store the cooled patties and gravy together in an airtight container for 3–4 days.

Frequently Asked Questions
Is Salisbury steak actually steak?
Salisbury steak is traditionally made from seasoned ground meat shaped into patties and served with gravy.
Do I need to brown the patties?
Browning is recommended because it adds flavor and helps the patties hold their shape.
Why did my patties fall apart?
The mixture may have lacked sufficient binder, been handled while very warm or moved too frequently during browning.
Can I use frozen hamburger patties?
Plain frozen patties can work, but they will lack the seasoning and binding ingredients in this recipe. Thaw them before slow cooking.
Can I omit the mushrooms?
Yes. Add additional sliced onion or leave the mushrooms out without replacement.
Can I use condensed mushroom soup?
Yes, but it creates a different sauce with more sodium and a thicker consistency.
