Few meals evoke as much nostalgia and comfort as Salisbury steak. With tender beef patties smothered in rich onion-mushroom gravy, it’s the kind of dish that brings back memories of hearty weeknight dinners and stick-to-your-ribs flavor. Traditionally cooked on the stovetop, this version takes a modern twist by using the slow cooker. The result? Melt-in-your-mouth patties, savory gravy, and an effortless cooking process make it perfect for busy days.
This Slow Cooker Salisbury Steak recipe is a lifesaver when you want a meal that tastes like it’s been fussed over all day—but really, your slow cooker is doing the work for you.
Ingredients
For the patties:
- 1 1/2 pounds ground beef
- 1 egg
- 1/4 cup minced onion
- 1/4 cup breadcrumbs
- 1 clove garlic, crushed
- 1/2 teaspoon salt
- 1/4 teaspoon pepper
For the gravy:
- 1 small onion, sliced
- 6 ounces mushrooms, sliced
- 1 1/2 cups beef broth
- 1 package brown gravy mix
- 1 tablespoon ketchup (optional)
- 1 tablespoon Dijon mustard (optional)
- 2 tablespoons cornstarch
Directions
- Make the patties
In a large bowl, mix ground beef, egg, minced onion, breadcrumbs, garlic, salt, and pepper. Combine just until everything comes together—overmixing can make the patties tough. Shape the mixture into small patties about 3/4 inch thick. - Prepare the slow cooker base.
Place the sliced onions and mushrooms at the bottom of the slow cooker. They’ll not only flavor the gravy but also create a cozy bed for the patties to rest on. - Brown for extra flavor
Heat a skillet over medium-high heat and quickly brown each patty on both sides. This step isn’t strictly necessary, but it adds a rich, caramelized layer of flavor you just can’t get from the slow cooker alone. Once browned, place the patties on top of the onion-mushroom mixture in the slow cooker. - Make the gravy base
In a bowl, whisk together the beef broth, brown gravy mix, ketchup (if using), and Dijon mustard (if using). Pour this mixture over the patties, onions, and mushrooms. Cover and cook on low for 5 hours. - Thicken the sauce
After cooking, carefully remove the patties from the slow cooker. Turn the heat to high, whisk in the cornstarch until smooth, and cook for approximately 10 minutes, or until the sauce has thickened to your desired consistency. - Finish and serve
Return the patties to the slow cooker, coat them with the thickened gravy, and serve hot.
Why This Recipe Works
This slow cooker method transforms simple ingredients into a deeply flavorful, satisfying dish. The combination of ground beef with onion, breadcrumbs, and garlic gives the patties a classic meatloaf-like texture—juicy, tender, and seasoned just right. Browning them beforehand may add a few minutes of prep time, but the payoff is huge: rich, savory flavor that sets the tone for the whole dish.
The onion and mushrooms cook low and slow, releasing natural sweetness and umami that enrich the gravy. The gravy mix and beef broth provide a rich, beefy base, while optional additions like ketchup and Dijon mustard add a subtle tang and complexity. Finally, thickening the sauce with cornstarch at the end makes it cling beautifully to the patties.
Serving Suggestions
Salisbury steak is all about the sides. Traditionally, it pairs perfectly with:
- Mashed potatoes – Creamy mashed potatoes pair beautifully with the rich gravy.
- Rice or buttered noodles – Both are excellent bases to carry the flavors of the dish.
- Steamed vegetables – Green beans, peas, or carrots add a pop of color and freshness.
- Buttered rolls – Perfect for mopping up every last bit of gravy.
This dish is equally suited for a casual family dinner or a cozy Sunday meal when you want something hearty without having to hover over the stove.
Tips for Success
- Use lean ground beef: An 85/15 blend works well, keeping the patties juicy but not greasy.
- Don’t skip browning: It’s tempting to drop raw patties straight into the slow cooker, but browning adds a depth of flavor that makes a huge difference.
- Adjust gravy thickness: If you prefer a thinner sauce, use less cornstarch. For a thicker, stick-to-your-fork gravy, let it cook a few extra minutes.
- Make ahead: You can prepare the patties a day in advance and refrigerate them. Just brown and cook when you’re ready.
