Slow cooker Salisbury steak turns seasoned beef patties, mushrooms, and onions into a comforting dinner with plenty of gravy for mashed potatoes. The patties get a quick sear before they go into the cooker, then simmer gently until cooked through and tender. A little cream stirred in at the end gives the mushroom-onion gravy its soft tan color and smooth finish.
This from-scratch version uses fresh ground beef, sliced mushrooms, beef broth, and simple seasonings. There is no packet of gravy mix or canned condensed soup in the sauce. Browning takes a few extra minutes, but it adds flavor and helps the patties stay together while they cook.

What is Salisbury steak?
Salisbury steak is made from seasoned ground beef shaped into patties and served with gravy. Breadcrumbs and egg help the meat hold together and give it a softer texture than a tightly packed burger. Mushrooms and onions add savory flavor to the sauce around it.
The slow cooker makes this a useful dinner for an afternoon at home: prepare the patties, let them cook gently, and finish the gravy shortly before serving. This recipe has a creamy gravy to match the featured dish. If you prefer a darker, more traditional brown gravy, you can leave out the cream.
Ingredients
For the beef patties
- 1 1/2 pounds (680 g) ground beef, preferably 85–90% lean
- 1/3 cup (35 g) plain dry breadcrumbs
- 1/4 cup (60 ml) milk
- 1 large egg
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1 teaspoon onion powder
- 1/2 teaspoon garlic powder
- 1/2 teaspoon fine salt
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon neutral oil, for searing
For the mushroom-onion gravy
- 8 ounces (225 g) button or cremini mushrooms, sliced
- 1 large yellow onion, thinly sliced into half-rings
- 2 garlic cloves, minced
- 1 1/2 cups (360 ml) low-sodium beef broth, divided
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Dijon mustard
- 1/2 teaspoon dried thyme
- 2 tablespoons cornstarch mixed with 2 tablespoons cold water
- 1/2 cup (120 ml) heavy cream
- Salt and pepper, to taste
- Chopped parsley, optional, for serving
Ingredient notes
Ground beef: A little fat keeps the patties moist, but very fatty beef leaves more grease to skim from the gravy. An 85–90% lean blend is a practical middle ground. Start with fully thawed beef.
Breadcrumbs and milk: Letting the crumbs soak briefly creates a soft mixture that blends into the meat. Plain crumbs give you control over seasoning. If using seasoned crumbs, check their salt content and adjust accordingly.
Mushrooms: Button mushrooms give a mild flavor, while cremini mushrooms bring a little more depth. Wipe or rinse them briefly, dry well, and slice evenly so they cook at a similar rate.
Broth: Use low-sodium broth because Worcestershire sauce and the patties already contribute salt. You can season the finished gravy after it has cooked.
Cream: Heavy cream is added at the end rather than cooked for hours. It gives the sauce a creamy finish without relying on condensed soup. Milk is thinner and will not give quite the same richness.
How to make slow cooker Salisbury steak
Step 1: Mix and shape the patties
In a large bowl, combine the breadcrumbs and milk and let stand for 2 minutes. Add the egg, Worcestershire sauce, Dijon, onion powder, garlic powder, salt, and pepper. Mix these ingredients first, then add the ground beef and combine gently just until evenly seasoned.
Divide into 6 equal portions and form broad oval or round patties about 3/4 inch thick. Keep the thickness even and avoid packing the meat tightly. Wash your hands and clean surfaces and utensils that touched the raw beef before handling cooked food.
Step 2: Sear the patties
Heat the oil in a large skillet over medium-high heat. Sear the patties in batches for about 2 minutes per side, until browned on the outside. Turn carefully with a wide spatula and avoid pressing down on them.
This is a browning step, not the final cooking stage. Transfer the patties to a clean heatproof plate while you quickly prepare the vegetables, then move straight into slow cooking. Do not partially cook the patties and refrigerate them to finish another day.
Step 3: Cook the mushrooms and onion briefly
Leave about 1 tablespoon of fat in the skillet, spooning off any large excess. Add the mushrooms and onion and cook over medium heat for 5–6 minutes, stirring occasionally, until the mushrooms release some liquid and the onion starts to soften. Stir in the garlic for the final 30 seconds.
Spread the vegetables across the bottom of the slow cooker. They do not need to be fully tender yet; they will finish cooking with the beef.
Step 4: Mix the gravy base
Pour 1/2 cup of the broth into the warm skillet and scrape up the browned bits with a wooden spoon. In a measuring jug, combine this liquid with the remaining 1 cup broth, Worcestershire sauce, Dijon, and thyme. Whisk until the mustard is dispersed.
The gravy base will look thin at this point. The cornstarch and cream go in near the end, after you can see how much liquid the meat and vegetables have released.
Step 5: Slow cook until the patties are done
Place the browned patties over the mushrooms and onions, overlapping only slightly if needed. Pour the broth mixture around them and cover. Cook on LOW for 4–5 hours or HIGH for 2–3 hours, starting to check at the earlier end of the range.
The center of each patty must reach 160°F (71°C). Insert a food thermometer from the side into the middle of the thickest patties. The meat should be cooked through and the vegetables tender; do not judge ground beef by its color alone. Avoid stirring during cooking, which can break the patties apart.
Step 6: Thicken and finish the gravy
Lift the patties onto a warm plate and cover loosely. Skim excess fat from the cooking liquid. Mix the cornstarch with the cold water until smooth, stir it into the gravy, and cook on HIGH for 15–20 minutes, or until thickened. If your cooker does not get hot enough to thicken the slurry, transfer the gravy to a saucepan and simmer briefly on the stove, stirring.
Stir in the heavy cream and heat gently until the sauce is hot throughout. Taste and add salt or pepper as needed. Return the patties carefully and spoon the mushrooms, onions, and gravy over them. Add parsley if using and serve hot.
Tips for tender patties and smooth gravy
- Mix gently. Overworking the beef can make the patties firm rather than tender.
- Keep the patties thick enough to lift. Very thin patties are easier to break during searing and serving.
- Brown in batches. Crowding the skillet encourages steaming and makes turning difficult.
- Do not add extra broth early. Mushrooms, onion, and beef release moisture as they cook.
- Use cold water for the slurry. Cornstarch mixed directly into hot gravy can form lumps.
- Finish dairy at the end. Adding cream after the gravy thickens gives you more control over the texture.
- Lift rather than stir. A wide spatula protects the cooked patties.
Simple variations
Brown gravy: Leave out the cream and finish the thickened mushroom-onion gravy with a small knob of butter if you like. The sauce will have a deeper brown color and a more pronounced beef flavor.
Without mushrooms: Omit them and add another half onion. The amount of liquid released will change, so judge the gravy before adding all the slurry.
With ground turkey: Turkey gives a lighter flavor and may need a little more oil for searing. Cook turkey patties to 165°F (74°C). Check them early rather than assuming the same timing as beef.
Gluten-free option: Use gluten-free breadcrumbs and check the broth, mustard, and Worcestershire sauce labels. Cornstarch thickens the gravy without flour, but packaged ingredients can vary.
What to serve with Salisbury steak
Mashed potatoes are a natural choice because they catch the gravy. Buttered egg noodles, rice, or a baked potato also work well. Add green beans, peas, steamed broccoli, or a crisp salad for something fresh alongside the rich sauce.
For another slow-cooked beef dinner, try our slow cooker beef and potatoes. It uses chuck pieces and golden potato rounds instead of ground-beef patties.
Make-ahead advice
Shape the raw patties up to a day ahead and refrigerate them, covered, at 40°F or below. Keep the sliced vegetables in a separate refrigerated container. Sear the patties and start the slow cooker when you are ready to cook.
Another option is to cook the entire meal ahead, cool it promptly in shallow containers, and refrigerate. Do not brown the outside of the patties, refrigerate them partially cooked, and plan to finish them later.
Storage and reheating
Refrigerate leftovers in shallow containers within 2 hours, or within 1 hour when the surrounding temperature is above 90°F. Keep the refrigerator at 40°F or below and use within 3–4 days. Store the patties with some gravy so they do not dry out.
Reheat covered in a skillet, microwave, or 325°F oven until the patties and gravy reach 165°F throughout. Bring reheated gravy to a boil, adding a splash of broth if needed and stirring gently around the patties. Do not use a slow cooker to reheat cold leftovers.
Freeze cooled portions for up to 2–3 months for best quality and thaw in the refrigerator before reheating. Cream-based gravy may separate slightly after freezing; gentle stirring can help bring it back together. For the smoothest freezer results, freeze the patties in the thickened gravy before adding the cream, then add cream when reheating.
Frequently asked questions
Can I skip browning the patties?
Browning adds flavor and helps set the outside, making the patties easier to handle. This recipe is written around that step. Skipping it changes the timing and texture, so it is better to follow the searing method for this version.
Why did my Salisbury steak fall apart?
The patties may have been too thin, turned before a crust formed, or stirred during slow cooking. The egg and breadcrumbs help bind the mixture. Use a wide spatula and turn or lift gently rather than grabbing the patties with tongs.
Why is the gravy thin?
Slow cookers retain moisture, and vegetables release extra liquid. Thicken the gravy near the end rather than adding more cornstarch at the start. If the slurry does not activate in your cooker, simmer the liquid in a saucepan before returning it to the patties.
Can I use frozen patties?
Thaw homemade raw patties completely in the refrigerator first, then sear and cook as directed. Do not put frozen raw ground beef patties into the slow cooker for this recipe.
Is Salisbury steak the same as hamburger steak?
They are closely related ground-beef dishes. Salisbury steak commonly includes a binder and seasonings mixed into the meat and is served with gravy; hamburger steak can be simpler. Names and preparations vary, but this version includes breadcrumbs, egg, and mushroom-onion gravy.
Can I double this recipe?
Use two cookers if doubling would crowd the patties or exceed your appliance’s recommended fill level. Deep stacks make the patties harder to lift and can affect cooking time. Check the temperature of several patties before serving.
