Ingredients
For the Salisbury Steaks
| Ingredient | Quantity |
| Ground beef, preferably 80/20 | 1½–2 lbs (680–900 g) |
| Salt | To taste |
| Black pepper | To taste |
| Garlic powder or minced garlic | 1 teaspoon |
For the Onion Gravy
| Ingredient | Quantity |
| Large yellow onions, roughly chopped or sliced | 2–3 |
| Beef broth | 2 cups (500 ml) |
| Dry onion soup mix | 1 packet |
| Garlic, minced (optional) | 2 cloves |
For Thickening the Gravy (Optional)
| Ingredient | Quantity |
| Cornstarch | 1 tablespoon |
| Cold water | 2 tablespoons |
Step-by-Step Instructions
1. Prepare the Onion Base
Place the chopped or sliced onions evenly across the bottom of your slow cooker.
Add the minced garlic or garlic seasoning.
Pour in the beef broth and sprinkle the dry onion soup mix over the mixture. Stir gently to combine.
The onions will create a flavorful base for the beef patties as they cook.
2. Shape the Ground Beef Patties
Place the ground beef in a large mixing bowl.
Season with salt, black pepper, and garlic powder.
Gently mix until the seasonings are evenly distributed. Divide the beef into four large portions and shape each portion into a thick oval patty.
Avoid overmixing the beef, as this can make the patties dense.
3. Add the Patties to the Slow Cooker
Carefully place the raw beef patties directly on top of the onion and broth mixture.
Arrange them in a single layer whenever possible.
The patties should rest gently over the onions without being completely submerged.
4. Slow Cook Until Tender
Cover the slow cooker with its lid and cook according to your preferred setting:
- LOW: 4–6 hours.
- HIGH: Approximately 3 hours.
Cooking time may vary depending on the thickness of the patties and your slow cooker.
The patties should be fully cooked and tender, and the onions should be soft and flavorful.
For food safety, ground beef should reach an internal temperature of 160°F (71°C), checked with a food thermometer.
5. Remove the Salisbury Steaks
Once cooked, carefully lift the beef patties out of the slow cooker using a spatula.
Place them on a serving plate and keep warm while preparing the gravy.
Be gentle when handling the patties because they will be soft and delicate after slow cooking.
6. Thicken the Onion Gravy
If you prefer a thicker, richer gravy, mix the cornstarch and cold water in a small bowl until completely smooth.
Pour the slurry into the hot cooking liquid in the slow cooker.
Stir gently, cover, and cook on HIGH for approximately 10–15 minutes, or until the gravy thickens.
Alternatively, transfer the cooking liquid to a saucepan and simmer over medium heat until it reaches your preferred consistency.
7. Return the Steaks to the Gravy
Place the cooked Salisbury steaks back into the slow cooker.
Spoon the onion gravy generously over each patty and let everything sit together for a few minutes.
This allows the beef to soak up even more of the delicious onion flavor.
8. Serve and Enjoy
Transfer the Salisbury steaks to individual plates and cover generously with the rich onion gravy and tender cooked onions.
Serve hot with creamy mashed potatoes, white rice, or buttered egg noodles.
Enjoy this comforting homemade beef dinner!
Best Tips for Perfect Slow Cooker Salisbury Steak
Choose ground beef with around 80/20 fat content for juicy, flavorful patties. Leaner ground beef can also work, but the steaks may be slightly less tender.
Shape the patties evenly so they cook at approximately the same rate. Making them too thick can increase the cooking time.
Avoid overmixing the ground beef when shaping the patties. Gentle handling helps keep the texture tender.
For a richer flavor, brown the patties in a skillet for 2–3 minutes per side before adding them to the slow cooker. This is optional but adds extra depth.
Finally, always thicken the gravy at the end of cooking rather than adding cornstarch directly to the cold broth.
Best Ingredient Options
Ground Beef: An 80/20 or 85/15 ground beef blend works wonderfully for juicy Salisbury steaks.
Onions: Yellow onions are ideal because they become soft and naturally sweet during slow cooking. White onions are another good option.
Beef Broth: Regular beef broth creates a rich, savory gravy. Low-sodium broth is a good choice if you want to control the salt.
Onion Soup Mix: A packet of dry onion soup mix adds convenient seasoning and enhances the gravy. You can also use homemade onion seasoning.
Garlic: Fresh minced garlic provides a stronger aroma, while garlic powder offers a convenient alternative.
Cornstarch: Cornstarch thickens the gravy quickly. Flour can also be used, although it requires a slightly different preparation.
Recipe Variations
Mushroom Salisbury Steak: Add 8 ounces of sliced mushrooms to the onion mixture for a classic beef and mushroom gravy.
Creamy Salisbury Steak: Stir ¼ cup of heavy cream or a few tablespoons of sour cream into the finished gravy for a creamier texture.
Garlic Butter Salisbury Steak: Add 1 tablespoon of butter and extra minced garlic to the gravy for a richer flavor.
Worcestershire Salisbury Steak: Add 1 tablespoon of Worcestershire sauce to the beef broth for extra savory depth.
Cheesy Salisbury Steak: Sprinkle shredded mozzarella or provolone over the patties during the final few minutes of cooking.
Homemade Beef Gravy: Replace the onion soup mix with beef bouillon, onion powder, garlic powder, Worcestershire sauce, and a little dried thyme.
What to Serve With Slow Cooker Salisbury Steak
Creamy mashed potatoes are the classic side dish for Salisbury steak. They soak up the delicious onion gravy and create a wonderfully comforting meal.
Buttered egg noodles, steamed white rice, or roasted potatoes are also excellent choices.
For vegetables, serve the beef with roasted carrots, green beans, steamed broccoli, or sautéed cabbage.
You can also add a fresh garden salad or warm dinner rolls to complete the meal.
Make-Ahead Instructions
You can prepare the onion gravy mixture up to 24 hours in advance.
Chop the onions, mince the garlic, and combine the beef broth with the onion soup mix. Store the mixture in an airtight container in the refrigerator.
You can also shape the beef patties ahead of time and refrigerate them separately.
When ready to cook, place the onion mixture in the slow cooker, arrange the patties on top, and follow the cooking instructions.
For food safety, keep raw ground beef refrigerated until cooking.
Storage
Allow leftover Salisbury steaks and gravy to cool slightly before transferring them to airtight containers.
Store the patties together with the onion gravy to help keep them moist.
Refrigerate for up to 3–4 days.
For convenient meal prep, divide the steaks, gravy, and side dishes into individual portions.
Reheating
Microwave: Place one patty in a microwave-safe dish with plenty of onion gravy. Cover loosely and heat in 30-second intervals until thoroughly hot.
Oven: Arrange the steaks in an oven-safe dish, spoon gravy over the top, cover with foil, and reheat at 325°F (165°C) until heated through.
Stovetop: Place the steaks and gravy in a covered skillet over low heat. Warm gently, turning the patties carefully if needed.
Add a splash of beef broth if the gravy becomes too thick during reheating.
Freezing
Salisbury steak with onion gravy freezes very well.
Allow the cooked patties and gravy to cool completely.
Transfer them into freezer-safe containers, making sure each patty is covered with gravy to help prevent drying.
Freeze for up to 2–3 months for the best quality.
When ready to enjoy, thaw overnight in the refrigerator and reheat gently until steaming hot throughout.
Common Mistakes to Avoid
Overmixing the Ground Beef: Mixing too much can make the patties dense and tough. Combine the ingredients gently.
Making the Patties Too Thick: Very thick patties may take longer to cook. Shape them evenly for consistent results.
Skipping the Onion Base: The onions provide flavor and help create the delicious gravy that makes this recipe special.
Adding Too Much Salt: Onion soup mix and beef broth can already contain significant amounts of sodium. Taste the gravy before adding extra salt.
Adding Cornstarch Directly: Always dissolve cornstarch in cold water before adding it to hot liquid to prevent lumps.
Not Checking the Internal Temperature: Ground beef patties must reach 160°F (71°C) for food safety.
Removing the Patties Too Roughly: Slow-cooked patties can become delicate. Use a wide spatula to keep them intact.
