For the Mushroom and Onion Gravy
| Ingredient | Quantity | Notes |
| Cremini or button mushrooms | 8 oz (225 g) | Cleaned and sliced |
| Yellow onion | 1 large | Sliced into half-moons |
| Beef broth | 2 cups (480 ml) | Preferably lower-sodium |
| Brown gravy mix | 1 packet (about 25 g) | Use a compatible beef-style gravy mix |

Step-by-Step Instructions
Step 1: Prepare the Beef Patties
In a large mixing bowl, combine the ground beef, breadcrumbs, egg, dry onion soup mix, ketchup, 2 tablespoons of Worcestershire sauce, black pepper, and a small amount of salt if needed.
Mix gently with your hands or a fork until the ingredients are evenly combined. Avoid overmixing, as this can make the patties dense.
Divide the mixture into 5–6 equal portions and shape each portion into an oval patty about ¾ inch thick.
Step 2: Brown the Patties
Heat a large skillet over medium-high heat and add a small amount of cooking oil.
Working in batches if necessary, sear the patties for approximately 2–3 minutes per side, until nicely browned on the outside.
The patties do not need to be fully cooked at this stage. Browning adds flavor and helps the finished dish develop a richer, more appetizing appearance.
Transfer the browned patties to a plate.
Step 3: Prepare the Mushrooms and Onions
Wash or gently wipe the mushrooms clean, then slice them evenly.
Peel the onion and cut it into thin half-moons.
Spread the sliced onions and mushrooms across the bottom of a 5- to 6-quart slow cooker. This creates a flavorful bed for the beef patties and allows the vegetables to soften as they cook.
Step 4: Arrange the Beef Patties
Place the browned patties over the mushroom and onion mixture.
Arrange them in a single layer when possible. If you need to stack them, separate the layers with some of the vegetables to help distribute the sauce.
Step 5: Prepare the Gravy
In a medium bowl or measuring jug, whisk together the beef broth, brown gravy mix, and remaining 1 tablespoon of Worcestershire sauce.
Continue whisking until the gravy mix is dissolved and the liquid is mostly smooth.
Pour the mixture evenly over the patties, mushrooms, and onions.
Step 6: Slow Cook Until Tender
Cover the slow cooker with its lid and cook according to your preferred setting:
- LOW: 5–6 hours.
- HIGH: 3–4 hours.
Cooking time varies depending on your slow cooker and the thickness of the patties. Check that the ground beef patties reach an internal temperature of 160°F (71°C).
The onions should be soft, the mushrooms tender, and the patties cooked through.
Step 7: Thicken the Gravy
About 20–30 minutes before serving, combine the cornstarch and cold water in a small bowl. Stir until the mixture is completely smooth.
Carefully move the patties aside just enough to access the cooking liquid. Slowly stir the cornstarch slurry into the gravy, taking care not to break the patties.
Cover and cook on HIGH for approximately 15–20 minutes, or until the gravy reaches your preferred consistency.
If the sauce becomes too thick, stir in a small amount of beef broth. If it is still too thin, prepare a little additional cornstarch slurry and add it gradually.
Step 8: Garnish and Serve
Sprinkle the finished Salisbury steaks with freshly chopped parsley.
Serve the patties hot with generous spoonfuls of mushroom and onion gravy. Creamy mashed potatoes, buttered egg noodles, steamed rice, or crusty bread are excellent accompaniments.
Enjoy this comforting homemade dinner while the gravy is warm and flavorful.
Best Tips for Success
Choose the right ground beef. An 85/15 blend offers a good balance of flavor and moisture. Leaner beef can also work, although the patties may be slightly less juicy.
Do not overmix the meat. Mixing the ingredients just until combined helps keep the patties tender rather than firm or rubbery.
Brown the patties before slow cooking. This step is optional, but it adds a deeper roasted flavor to the beef and the finished gravy.
Use lower-sodium broth when possible. Onion soup mix and gravy mix can both contain substantial amounts of salt. Lower-sodium broth gives you more control over the final seasoning.
Add the cornstarch slurry near the end. Adding it too early can make the gravy less predictable. Stir it into the hot cooking liquid toward the end of the cooking time.
Handle the patties gently. Ground beef patties can break apart if stirred aggressively. Use a wide spatula when moving them and stir the sauce around them rather than through them.
Best Ingredient Options
Ground beef: An 85/15 blend is a reliable choice for flavorful patties. Very lean beef works too, but avoid overmixing or overcooking.
Breadcrumbs: Plain breadcrumbs allow you to control the seasoning, while seasoned breadcrumbs add extra herbs and spices. Gluten-free breadcrumbs can be used if needed.
Mushrooms: White button mushrooms have a mild flavor, while cremini mushrooms provide a deeper, earthier taste.
Beef broth: Regular beef broth creates a rich gravy, but lower-sodium broth is helpful if the seasoning mixes are salty.
Gravy mix: Choose a brown beef-style gravy mix and check its ingredient list if you have dietary restrictions. You can also make a homemade gravy base with broth, flour or cornstarch, and seasonings.
Worcestershire sauce: This adds savory complexity. Check the product label if you need to avoid specific ingredients, as formulations vary between brands.
Recipe Variations
Salisbury Steak with Extra Mushrooms
If you love mushrooms, increase the quantity to 12–16 ounces (340–450 g). The additional mushrooms add texture and flavor to the gravy. You may need a little extra broth if you want more sauce.
Garlic and Herb Salisbury Steak
Add 2 minced garlic cloves, ½ teaspoon dried thyme, and a little rosemary to the gravy mixture. These seasonings give the dish a deeper, herbaceous flavor.
Salisbury Steak with Carrots
Add 2 sliced carrots to the slow cooker with the onions and mushrooms. Cut them into relatively thin pieces so they have enough time to become tender.
Homemade Brown Gravy
For a more homemade flavor, replace the packaged gravy mix with a roux-based sauce. Melt 2 tablespoons of butter in a saucepan, whisk in 2 tablespoons of flour, and cook briefly. Gradually whisk in 2 cups of beef broth, then season with black pepper, garlic powder, and a small amount of Worcestershire sauce.
Pour the prepared gravy over the patties and vegetables before slow cooking. Adjust the final thickness as needed.
Gluten-Free Salisbury Steak
Use certified gluten-free breadcrumbs, a gluten-free gravy mix, and Worcestershire sauce that meets your dietary requirements. Check all ingredient labels carefully, as packaged soup and gravy mixes may contain wheat.
Creamy Mushroom Gravy
For a creamier sauce, stir a small splash of cream into the finished gravy near the end of cooking. Heat gently and avoid boiling the sauce vigorously. This variation changes the traditional brown gravy into a richer, creamy mushroom sauce.
What to Serve With Salisbury Steak
Creamy mashed potatoes are a classic pairing. The smooth potatoes soak up the mushroom and onion gravy, making every bite comforting and satisfying.
Egg noodles provide a soft, buttery base that complements the tender beef patties. Toss the noodles with a little butter and parsley before serving.
Steamed white rice is a simple option that absorbs the savory sauce and makes the meal easy to portion.
Roasted green beans, carrots, or broccoli add color and freshness to balance the rich gravy.
Crusty bread or dinner rolls are perfect for enjoying every last spoonful of sauce.
Make-Ahead Instructions
You can prepare the beef patties a day ahead and store them covered in the refrigerator. Slice the mushrooms and onions in advance and keep them in a separate airtight container.
For the best food safety, keep raw ground beef refrigerated at 40°F (4°C) or below and cook it within the recommended storage period. Assemble the ingredients shortly before starting the slow cooker rather than leaving raw meat at room temperature.
If preparing the meal for a busy day, measure out the gravy ingredients ahead of time so everything is ready to add.
Storage Instructions
Allow leftovers to cool slightly and transfer them to shallow, airtight containers. Refrigerate within two hours of cooking.
Store the Salisbury steaks and gravy in the refrigerator for 3–4 days. Keeping the patties covered with gravy helps them remain moist.
Reheating Instructions
Stovetop: Place the patties and gravy in a covered skillet or saucepan. Warm over medium-low heat, adding a splash of beef broth if the sauce has thickened too much.
Microwave: Place one portion in a microwave-safe dish and cover loosely. Heat in short intervals, turning or stirring the gravy as needed for even heating.
Oven: Arrange the patties and gravy in an oven-safe dish, cover with foil, and heat at 325°F (165°C) until thoroughly warmed.
Reheat leftovers to an internal temperature of 165°F (74°C). Avoid reheating the same portion multiple times.
Can You Freeze Salisbury Steak?
Yes! Salisbury steak freezes well, making it a convenient meal for future dinners.
Allow the patties and gravy to cool, then place them in freezer-safe containers. Keep the patties covered with gravy to help prevent them from drying out.
Freeze for up to 2–3 months for best quality. Thaw overnight in the refrigerator and reheat until the center reaches 165°F (74°C).
The gravy may separate slightly after freezing, but stirring it gently while reheating usually helps restore its texture.
Common Mistakes to Avoid
Overworking the ground beef: Mixing too much can create dense, firm patties. Combine the ingredients gently and stop as soon as they are evenly distributed.
Skipping browning when you want deeper flavor: The recipe will still work without searing, but browning adds a richer taste and more appealing color.
Adding too much salt: Packaged onion soup and gravy mixes are often salty. Taste the gravy before adding extra salt, especially if you are using regular beef broth.
Stirring the patties too aggressively: Ground beef patties can break apart during slow cooking. Handle them gently and avoid unnecessary stirring.
Adding the cornstarch directly without mixing it with water: Dry cornstarch can form lumps. Always mix it with cold water first to make a smooth slurry.
Cooking without checking the temperature: The cooking time is a guideline, not a guarantee. Use a food thermometer to confirm that the beef patties reach 160°F (71°C).

Frequently Asked Questions
What is Salisbury steak?
Salisbury steak is a classic comfort-food dish made from seasoned ground beef shaped into oval patties and served with gravy. Unlike a whole-cut steak, it uses ground beef mixed with ingredients such as breadcrumbs and egg.
Can I make Salisbury steak without browning the patties?
Yes. You can place the raw shaped patties directly into the slow cooker over the onions and mushrooms, then pour the gravy mixture over them. Browning is recommended for extra flavor, but it is not essential. Ensure the patties reach 160°F (71°C).
Can I use frozen ground beef patties?
Do not put frozen ground beef patties directly into the slow cooker. Thaw them safely in the refrigerator before cooking so they heat more predictably.
Why is my gravy too thin?
Vegetables release moisture during slow cooking, which can dilute the sauce. Add a cornstarch slurry near the end and cook for another 15–20 minutes, or until the gravy thickens.
Can I make this recipe without packaged soup mix?
Yes. Season the patties with onion powder, garlic powder, black pepper, and a small amount of salt instead. You can also add dried parsley or thyme for extra flavor.
Can I use another type of mushroom?
Absolutely. Button and cremini mushrooms are excellent choices, but sliced portobello mushrooms or a mushroom blend can also work. Cut larger mushrooms into manageable pieces.
Can I cook this recipe on HIGH all day?
It is best to follow the recommended cooking window and check the patties for doneness. Cooking for too long can make the texture less pleasant. Once fully cooked, use your slow cooker’s keep-warm setting according to its manufacturer’s instructions.
What should I serve with Salisbury steak?
Mashed potatoes, egg noodles, rice, roasted vegetables, green beans, and crusty bread all pair well with the rich mushroom gravy.
