Ingredients
For the Beef Patties
- 2 pounds ground beef
- 1/2 cup breadcrumbs
- 1 large egg
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon olive oil, for browning
For the Onion Gravy
- 2 large yellow onions, sliced
- 2 cups beef broth
- 1 packet brown gravy mix
- 2 tablespoons ketchup
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Dijon mustard, optional
- 1 teaspoon minced garlic
- 1 tablespoon cornstarch
- 2 tablespoons cold water
- Fresh parsley, optional, for garnish
Instructions
Step 1: Prepare the Beef Mixture
In a large bowl, combine the ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper.
Mix gently with your hands until the ingredients are evenly combined. Avoid overmixing, as this can make the patties dense instead of tender.
Divide the mixture into six or eight portions and shape each one into an oval patty approximately 3/4 inch thick. Press the centers slightly to help the patties maintain their shape during cooking.
Step 2: Brown the Patties
Heat the olive oil in a large skillet over medium-high heat.
Add the patties in batches and brown them for approximately two to three minutes per side. They do not need to cook completely at this stage because they will finish cooking in the slow cooker.
Browning develops a flavorful crust and creates browned bits in the skillet that can enhance the gravy.
Transfer the browned patties to a plate. Drain excess grease from the skillet if necessary, leaving a small amount for the onions.
Step 3: Prepare the Onion Gravy
In a bowl, whisk together the beef broth, brown gravy mix, ketchup, Worcestershire sauce, Dijon mustard, and minced garlic until smooth.
Scrape up the browned bits from the skillet with a little of the broth mixture, then stir them into the remaining gravy. This adds extra depth and richness.
Taste the mixture before adding additional salt because packaged gravy mix and beef broth can already contain plenty of sodium.
Step 4: Layer the Onions and Beef
Spread half of the sliced onions across the bottom of the slow cooker.
Arrange the browned beef patties on top, overlapping them slightly if necessary. Scatter the remaining onions over and around the patties.
Pour the prepared gravy mixture evenly over everything, making sure the onions are coated.
The onions will soften as they cook, releasing their natural sweetness into the savory gravy.
Step 5: Slow Cook Until Tender
Cover and cook on LOW for approximately four to six hours or on HIGH for two to three hours, depending on your slow cooker and the thickness of the patties.
The beef should become tender, and the onions should be soft and coated in rich brown gravy.
Check the thickest patty with a food thermometer. Ground beef should reach an internal temperature of 160°F (71°C) for food safety.
Avoid lifting the lid repeatedly because this releases heat and can extend the cooking time.
Step 6: Thicken the Gravy
If you prefer a thicker gravy, mix the cornstarch with the cold water in a small bowl until smooth.
Stir the slurry into the gravy around the patties during the final 15–20 minutes of cooking. Cover and continue cooking until the sauce thickens.
If the gravy is already thick enough, you can skip this step.
For an even richer finish, spoon some of the hot gravy over the patties just before serving.
Step 7: Serve and Enjoy
Carefully transfer the beef patties to a serving platter. Spoon the tender onions and rich brown gravy generously over the top.
Garnish with freshly chopped parsley if desired.
Serve immediately with mashed potatoes, steamed rice, egg noodles, roasted vegetables, or warm dinner rolls to soak up every bit of the delicious sauce.
Tips for the Best Salisbury Steak
- Choose ground beef with some fat: Ground beef around 80/20 or 85/15 produces flavorful, juicy patties.
- Brown before slow cooking: This step adds color and deeper flavor to the finished dish.
- Slice the onions evenly: Similar-sized slices cook more consistently and become beautifully tender.
- Avoid overmixing: Gently combining the ingredients helps keep the patties soft.
- Adjust the gravy: Add a little extra beef broth if the sauce becomes too thick, or use the cornstarch mixture if it is too thin.
- Season carefully: Taste the gravy before adding more salt, especially when using packaged mixes.
What to Serve with Salisbury Steak
Creamy mashed potatoes are a classic choice because they soak up the savory onion gravy beautifully. Buttered egg noodles and steamed white rice are also excellent options.
For a balanced meal, serve the beef with roasted carrots, green beans, broccoli, or a crisp green salad. Fresh dinner rolls are perfect for enjoying any gravy left on the plate.
Storage and Reheating
Allow leftovers to cool slightly and transfer them to airtight containers. Refrigerate within two hours of cooking and store for up to three to four days.
Reheat the patties and gravy in a covered saucepan over medium-low heat until thoroughly hot, adding a splash of beef broth if the sauce has thickened too much. You can also reheat individual portions in the microwave, stirring or turning the food as needed for even heating.
For longer storage, freeze the cooked patties with the gravy in freezer-safe containers for up to three months for best quality. Thaw in the refrigerator before reheating.
Frequently Asked Questions
Can I make Salisbury steak without browning the patties?
Yes, although browning adds extra flavor and improves the appearance. If you are short on time, you can place the shaped patties directly into the slow cooker, provided you cook them thoroughly to a safe internal temperature.
Can I use frozen beef patties?
Thaw the patties safely in the refrigerator before preparing this recipe. Starting with thawed patties helps ensure more predictable cooking and makes it easier to brown them properly.
Can I make the gravy from scratch?
Absolutely. Replace the packaged gravy mix with additional beef broth and a mixture of butter, flour, and seasonings. Cook the butter and flour together briefly to form a roux, then gradually whisk in the broth before combining it with the remaining gravy ingredients.
Why are my beef patties falling apart?
The mixture may need a little more binding, or the patties may have been handled too roughly. Make sure you include the egg and breadcrumbs, shape the patties firmly, and brown them carefully before transferring them to the slow cooker.
