Ingredients
For the Salisbury Steak Patties
| Ingredient | Quantity |
| Ground beef (80/20 or 85/15) | 1½ lbs (680 g) |
| Breadcrumbs | ¼ cup |
| Large egg | 1 |
| Worcestershire sauce | 1 tablespoon |
| Garlic powder | 1 teaspoon |
| Onion powder | 1 teaspoon |
| Salt | To taste |
| Black pepper | To taste |
| Olive oil (for searing) | 1 tablespoon, optional |
For the Onion Gravy
| Ingredient | Quantity |
| Large yellow onions, thinly sliced | 2 |
| Beef broth | 1½ cups |
| Brown gravy mix | 1 packet |
| Worcestershire sauce | 1 tablespoon |
| Butter | 2 tablespoons, optional |
Step-by-Step Instructions
Step 1: Prepare the Beef Mixture
In a large mixing bowl, combine the ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper.
Mix gently with your hands or a fork until everything is just combined. Avoid overmixing, as this can make the patties dense and tough.
Step 2: Shape the Salisbury Steaks
Divide the beef mixture into 4–6 equal portions. Shape each portion into an oval-shaped patty, approximately ¾ inch thick.
Make sure the patties are evenly sized so they cook consistently in the slow cooker.
Step 3: Brown the Patties (Optional but Recommended)
Heat the olive oil in a large skillet over medium-high heat.
Sear the beef patties for approximately 1–2 minutes per side, just until nicely browned on the outside. They do not need to be fully cooked at this stage.
Transfer the browned patties to a plate.
This optional step adds extra flavor and helps the patties hold their shape during slow cooking.
Step 4: Prepare the Slow Cooker
Arrange the sliced yellow onions evenly across the bottom of your slow cooker.
Place the beef patties over the onions in a single layer whenever possible. If necessary, slightly overlap them.
The onions will soften as they cook and release their natural sweetness into the gravy.
Step 5: Make the Brown Onion Gravy
In a medium mixing bowl, whisk together the beef broth, brown gravy mix, and Worcestershire sauce until the gravy mix is completely dissolved.
Pour the mixture evenly over the beef patties and onions.
If desired, add the butter in small pieces over the top for a richer, silkier gravy.
Step 6: Slow Cook Until Tender
Cover the slow cooker with its lid and cook:
- Low: 5–6 hours.
- High: 3–4 hours.
Cook until the beef patties are fully cooked and tender, reaching an internal temperature of 160°F (71°C).
The onions will become soft, and the gravy will develop a rich, savory flavor as everything slowly cooks together.
Step 7: Serve and Enjoy
Carefully transfer the Salisbury steaks to serving plates.
Spoon plenty of the warm onion gravy and tender onions over each patty.
Serve immediately with creamy mashed potatoes, steamed vegetables, rice, or buttered egg noodles.
Enjoy this comforting homemade dinner!
Best Tips for Perfect Salisbury Steaks
For the juiciest Salisbury steaks, choose ground beef with approximately 80–85% lean meat. A little fat helps keep the patties moist throughout the long cooking process.
Mix the ingredients gently and avoid compacting the beef too much when shaping the patties. Overworking the meat can result in a firm texture instead of tender, juicy steaks.
Although browning the patties is optional, it is highly recommended. A quick sear creates a delicious golden crust and adds deeper beef flavor to the finished gravy.
Slice the onions thinly and distribute them evenly throughout the slow cooker. They will soften beautifully and add natural sweetness to the brown gravy.
If the gravy is thinner than you prefer, mix 1 tablespoon of cornstarch with 1 tablespoon of cold water. Stir this slurry into the hot gravy and cook uncovered for approximately 10–15 minutes, until thickened.
Best Ingredient Options
Ground Beef: An 80/20 ground beef blend gives the patties a juicy, flavorful texture. You can also use 85/15 for a slightly leaner option.
Breadcrumbs: Plain breadcrumbs work perfectly, but seasoned breadcrumbs can add extra flavor. Panko can also be used for a slightly lighter texture.
Yellow Onions: Yellow onions are ideal because they become sweet and tender during slow cooking. White onions are another good option.
Beef Broth: Regular or low-sodium beef broth works well. Low-sodium broth gives you more control over the saltiness.
Brown Gravy Mix: A store-bought brown gravy packet makes preparation easy. You can also use homemade brown gravy seasoning if preferred.
Worcestershire Sauce: This ingredient adds a deep, savory, slightly tangy flavor that complements the beef.
Butter: Butter is optional, but it adds richness and creates a smoother-tasting gravy.
Recipe Variations
Mushroom Salisbury Steaks: Add 8 ounces of sliced mushrooms along with the onions for an earthy, savory flavor.
Creamy Salisbury Steaks: Stir ¼ cup of heavy cream or sour cream into the finished gravy for a creamy variation.
Garlic Onion Gravy: Add 2–3 minced garlic cloves to the onions for extra savory flavor.
Cheesy Salisbury Steaks: Sprinkle shredded cheddar or provolone over the patties during the final 10–15 minutes of cooking.
Homemade Brown Gravy: Replace the packaged gravy mix with a homemade mixture of butter, flour, beef broth, garlic powder, and seasonings.
Mushroom and Onion Gravy: Combine sliced mushrooms and onions for an even heartier gravy that pairs beautifully with mashed potatoes.
What to Serve With Slow Cooker Salisbury Steaks
These Salisbury steaks are especially delicious served over creamy mashed potatoes because the potatoes soak up every drop of the rich onion gravy.
Buttered egg noodles, steamed white rice, or fluffy rice pilaf are also excellent choices. For vegetables, try roasted carrots, green beans, steamed broccoli, or peas to balance the richness of the beef.
If you want a complete comfort-food dinner, serve everything with warm dinner rolls or homemade biscuits to soak up the extra gravy.
Make-Ahead Instructions
You can prepare the beef patties up to 24 hours ahead of time. Mix the ingredients, shape the patties, and arrange them in an airtight container with parchment paper between the layers. Refrigerate until ready to cook.
You can also slice the onions and prepare the gravy mixture separately. Store everything covered in the refrigerator until needed.
For the best results, keep the raw beef patties refrigerated at 40°F (4°C) or below and cook within 1–2 days of preparation.
Storage
Allow leftover Salisbury steaks and gravy to cool slightly before transferring them to an airtight container.
Refrigerate for up to 3–4 days at 40°F (4°C) or below.
Store the beef patties together with the onion gravy to help prevent them from drying out.
Reheating
Stovetop: Place the Salisbury steaks and gravy in a skillet over medium-low heat. Cover and warm gently until heated through, adding a splash of beef broth if the gravy becomes too thick.
Microwave: Transfer an individual portion to a microwave-safe dish. Cover loosely and heat in 30–60-second intervals, stirring the gravy between intervals, until thoroughly heated.
Slow Cooker: For larger portions, reheat on Low, stirring occasionally, until the food reaches 165°F (74°C). Avoid leaving leftovers in the slow cooker for extended periods.
Freezing
These Salisbury steaks freeze very well, making them a convenient meal-prep option.
Allow the cooked beef patties and gravy to cool completely. Transfer them to freezer-safe airtight containers or heavy-duty freezer bags.
Freeze for up to 3 months for best quality.
When ready to enjoy, thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave until the internal temperature reaches 165°F (74°C).
Common Mistakes to Avoid
Overmixing the Ground Beef: Mixing too aggressively can make the patties tough and dense. Combine the ingredients just until incorporated.
Making the Patties Too Thin: Thin patties can break apart during slow cooking. Shape them into evenly sized patties approximately ¾ inch thick.
Skipping the Gravy Mixing Step: Adding dry gravy powder directly into the slow cooker can create lumps. Always whisk it into the beef broth first.
Using Too Much Liquid: Adding extra broth can make the gravy watery. Follow the recommended quantities and adjust the consistency at the end if needed.
Cooking at Too High a Temperature for Too Long: Extended cooking can dry out the beef patties. Follow the recommended cooking times and check for doneness.
Forgetting to Check the Internal Temperature: Ground beef should reach 160°F (71°C) for food safety. Use a meat thermometer to check the center of the patties.
