What Is Salisbury Steak?
Salisbury steak is a traditional American-style dish made with seasoned ground beef shaped into oval patties. The patties are usually browned in a skillet and served with a savory gravy made from beef broth, onions, mushrooms, and seasonings.
Unlike a traditional steak, Salisbury steak uses ground beef mixed with ingredients such as breadcrumbs, eggs, and Worcestershire sauce. These ingredients help the patties hold their shape while adding flavor and moisture.
Cooking Salisbury steak in a slow cooker makes the dish especially convenient. The patties simmer gently in the gravy, allowing the flavors to develop while reducing the need for constant attention.
Preparation Time and Cooking Time
Preparation time: 20 minutes
Cooking time: 4–5 hours on LOW or approximately 2–3 hours on HIGH, depending on your slow cooker and patty thickness.
Total time: Approximately 4 hours 20 minutes to 5 hours 20 minutes on LOW.
Servings: 4–6 people
Difficulty: Easy
Ingredients You Will Need
For the beef patties:
Ground beef: 2 pounds, preferably 80–85% lean
Breadcrumbs: ½ cup
Egg: 1 large
Milk: ¼ cup
Worcestershire sauce: 1 tablespoon
Garlic powder: 1 teaspoon
Onion powder: 1 teaspoon
Black pepper: ½ teaspoon
Salt: ¾ teaspoon, or to taste
For the mushroom gravy:
Beef broth: 2 cups
Sliced mushrooms: 8 ounces
Yellow onion: 1 medium, thinly sliced
Garlic: 3 cloves, minced
Worcestershire sauce: 1 tablespoon
Soy sauce: 1 teaspoon, optional
Tomato paste: 1 tablespoon
Cornstarch: 2 tablespoons
Cold water: 2 tablespoons
Butter: 1 tablespoon
Dried thyme: ½ teaspoon
Black pepper: ¼ teaspoon
Fresh parsley: 1 tablespoon, chopped, for garnish
You can adjust the seasonings according to your taste. If you prefer a stronger mushroom flavor, add extra mushrooms. For a richer gravy, you can replace a small amount of the beef broth with additional broth made from roasted beef drippings.
Step 1: Prepare the Beef Mixture
Start by placing the ground beef in a large mixing bowl. Add the breadcrumbs, egg, milk, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper.
Mix the ingredients gently using clean hands or a fork until everything is combined.
Avoid overmixing the beef because doing so can make the patties firm and dense instead of tender. The breadcrumbs and milk help retain moisture, while the egg helps hold the patties together during cooking.
Once the mixture is ready, divide it into six equal portions.
Step 2: Shape the Salisbury Steak Patties
Take each portion of the beef mixture and shape it into an oval patty approximately ¾ inch thick.
Press the mixture gently so the patties hold their shape, but do not compact them too tightly.
Place the patties on a clean plate or tray. If the mixture feels too soft, refrigerate the shaped patties for about 10–15 minutes before browning.
Try to make the patties similar in thickness so they cook evenly in the slow cooker.
Step 3: Brown the Beef Patties
Heat a large skillet over medium-high heat and add a small amount of oil if needed.
Place the patties in the hot skillet, leaving space between them. Brown each side for approximately 2–3 minutes until a golden-brown crust develops.
The purpose of this step is to develop flavor and help the patties maintain their shape. They do not need to be completely cooked at this stage because they will finish cooking in the slow cooker.
Transfer the browned patties to a plate. If necessary, brown them in batches to avoid overcrowding the pan.
For the best results, do not skip browning unless you are short on time. Although the patties can be cooked without this step, browning usually produces a deeper, richer flavor.
Step 4: Prepare the Mushrooms and Onions
Using the same skillet, melt the butter over medium heat.
Add the sliced onions and cook for about 3 minutes until they begin to soften. Add the mushrooms and continue cooking for another 3–5 minutes.
Stir occasionally so the mushrooms cook evenly and release some of their moisture.
Add the minced garlic and cook for approximately 30 seconds. Avoid burning the garlic because it can make the gravy taste bitter.
Stir in the tomato paste, Worcestershire sauce, optional soy sauce, dried thyme, and black pepper.
These ingredients create a savory base that gives the finished gravy its rich color and deep flavor.
Step 5: Make the Gravy Base
Pour the beef broth into the skillet and stir well, scraping the bottom of the pan to release any browned bits.
Those browned bits contain concentrated flavor from the beef, mushrooms, and onions.
Allow the mixture to simmer gently for 1–2 minutes. You do not need to make the gravy thick at this point because it will continue developing as the Salisbury steak cooks.
Taste the liquid carefully and adjust the seasonings if necessary. Remember that beef broth and soy sauce can already contain a considerable amount of salt.
Step 6: Assemble Everything in the Slow Cooker
Arrange the browned beef patties in the bottom of your slow cooker. Depending on the size of your appliance, you may need to arrange them in slightly overlapping layers.
Pour the mushroom and onion gravy mixture over the patties.
Make sure the liquid reaches around the patties so they can cook gently and absorb the flavors. Add any remaining mushrooms and onions on top.
Cover the slow cooker with its lid.
Cook on LOW for approximately 4–5 hours or on HIGH for approximately 2–3 hours. Actual cooking time will vary depending on your slow cooker, the thickness of the patties, and how closely they are arranged.
The safest way to determine doneness is to check the center of a patty with a food thermometer. Ground beef should reach an internal temperature of 160°F (71°C).
Avoid repeatedly lifting the lid because doing so releases heat and can increase cooking time.
Step 7: Thicken the Mushroom Gravy
When the patties are fully cooked, carefully transfer them to a serving plate or leave them in the slow cooker if there is enough room to stir.
In a small bowl, combine the cornstarch with the cold water. Stir until the mixture is completely smooth.
Pour the slurry into the gravy while stirring gently.
Cover and cook on HIGH for another 10–15 minutes, or until the gravy reaches your preferred consistency. Slow cookers vary, so allow a little extra time if necessary.
If the gravy becomes too thick, add a small amount of beef broth and stir until smooth.
If you prefer a thinner gravy, use less cornstarch. For a particularly rich mushroom gravy, you can stir in a small amount of butter at the end.
Step 8: Return the Patties to the Gravy
If you removed the patties to thicken the sauce, return them to the slow cooker.
Spoon the gravy over each patty so that every piece is coated with the glossy brown sauce.
Allow everything to rest together for approximately 5 minutes before serving.
This final step helps the patties become evenly coated with the mushroom gravy and allows the flavors to come together.
Step 9: Garnish and Serve
Transfer the Salisbury steak to a serving dish and spoon plenty of mushroom gravy over the top.
Sprinkle with freshly chopped parsley for a touch of color and freshness.
For a meal similar to the one shown in the picture, arrange the patties close together in a shallow serving dish and pour the gravy generously over them.
Serve immediately while hot.
What to Serve with Salisbury Steak
Mashed potatoes are one of the most popular choices because they absorb the rich mushroom gravy beautifully. Creamy potatoes make the meal especially comforting.
Steamed white rice or brown rice is another excellent option. The rice soaks up the savory sauce and makes every bite flavorful.
Egg noodles pair wonderfully with the beef patties and mushrooms. Toss the cooked noodles with a little butter before serving.
For a lighter meal, serve Salisbury steak with steamed broccoli, green beans, roasted cauliflower, or a fresh green salad.
If you prefer a low-carb meal, cauliflower mash or cauliflower rice works particularly well with the mushroom gravy.
Tips for the Best Slow Cooker Salisbury Steak
Choose ground beef with enough fat to keep the patties moist. Very lean beef can become dry if overcooked.
Brown the patties before slow cooking whenever possible. This adds flavor and improves their appearance.
Do not overmix the beef mixture. Gentle mixing helps produce tender patties.
Use fresh mushrooms for a deeper, more natural mushroom flavor. White button mushrooms and cremini mushrooms both work well.
Taste the gravy before adding extra salt. Beef broth, Worcestershire sauce, and soy sauce can already be salty.
Add the cornstarch slurry near the end of cooking. Adding it too early can make the gravy less predictable in consistency.
Avoid cooking the patties for much longer than necessary. Once the ground beef reaches a safe temperature and the patties are cooked through, extended cooking can affect their texture.
Common Mistakes to Avoid
One common mistake is making the patties too thin. Thin patties can break apart more easily and may become overcooked before the gravy develops its full flavor.
Another mistake is adding dry cornstarch directly to the slow cooker. It can form lumps, so always mix it with cold water first.
Using too much liquid can also result in a thin gravy. Measure the beef broth carefully and thicken the sauce at the end if needed.
Finally, avoid stirring the patties too aggressively while they cook. Ground beef patties are delicate, particularly before they have fully set.
How to Store Leftovers
Allow the leftovers to cool slightly, then transfer them to an airtight container with the gravy.
Refrigerate within two hours of cooking and use within 3–4 days. Reheat the beef and gravy until they reach 165°F (74°C).
You can also freeze the cooked patties and gravy in a freezer-safe container for approximately 2–3 months for best quality. Thaw them in the refrigerator before reheating.
When reheating, add a small splash of beef broth if the gravy has become too thick. Heat gently on the stovetop or in the microwave, stirring the gravy as needed.
Frequently Asked Questions
Can I make Salisbury steak without mushrooms?
Yes. You can leave out the mushrooms and prepare the gravy with onions, beef broth, and seasonings. The result will still be savory and delicious.
Can I prepare the patties the night before?
Yes. You can shape the patties and refrigerate them in a covered container overnight. Brown them before adding them to the slow cooker the following day.
Can I use frozen ground beef patties?
Use fresh or fully thawed patties for this recipe. Do not put frozen ground beef patties directly into the slow cooker because they may remain at unsafe temperatures for too long.
Why is my gravy too thin?
Slow cookers trap moisture, which can leave the gravy thinner than expected. Add a cornstarch slurry near the end and cook until the sauce thickens.
Can I make this recipe gluten-free?
Yes. Use gluten-free breadcrumbs, certified gluten-free Worcestershire sauce and broth, and a gluten-free thickener such as cornstarch. Check every ingredient label to ensure it meets your dietary requirements.
