Before You Get Started

• Brown the patties first for the best flavor and texture. A quick sear in a hot skillet (about 3 minutes per side) gives the beef a rich, caramelized crust and helps the patties hold together in the slow cooker. You can skip this step if you’re short on time, but browning adds depth to both the meat and the gravy.
• Don’t skimp on the binder. The breadcrumbs keep your patties from falling apart during the long cook time. Mix them in gently but thoroughly, and avoid overmixing or the patties can turn dense.
• Layer the vegetables on the bottom. Placing the onions and mushrooms underneath the patties ensures that they soften by the end of the cooking time, while also adding flavor to the gravy as everything cooks together.

How to Make Slow Cooker Salisbury Steak

Step 1: Mix the Beef Patty Ingredients

Start by mixing together the ground beef, breadcrumbs, onion soup mix, and milk in a large bowl. Use your hands or a fork to combine everything gently but thoroughly. 

You want the ingredients evenly distributed, but avoid overmixing or you’ll end up with dense, tough patties. 

The breadcrumbs act as a binder to help the patties hold their shape during the long, slow cook.

** Pro Tip: Using the whole packet of soup mix yields patties that are quite salty. For a less salty dish, use just half of the soup mix packet. You’ll still have flavorful patties with much less salt.

Step 2: Shape the Patties

Shape the mixture into 4 round or oval patties, about 3/4-inch thick. Make them slightly thinner in the center so they cook evenly and don’t puff up too much.

Step 3: Brown the Patties (Optional but Recommended)

Heat a large skillet over medium-high heat with about a tablespoon of oil. Once the pan is hot, add the patties and sear for 2-3 minutes per side until they’re nicely browned. 

You’re not cooking them through at this stage, just creating a flavorful crust that will add depth to the finished dish. The browning also helps the patties stay intact in the slow cooker.

** Quick Note: Short on time? You can skip the browning step and place the raw patties directly into the slow cooker. They’ll still cook through and taste great, but you’ll miss out on some of that rich, caramelized flavor.

Step 4: Layer the Vegetables

While the patties brown, scatter the sliced onions and mushrooms across the bottom of your slow cooker. This creates a flavorful base and keeps the patties elevated slightly so the gravy can circulate underneath. 

Place the browned patties on top of the vegetables in a single layer.

Step 5: Prepare the Gravy

In a medium bowl, whisk together the cream of mushroom soup, au jus mix, and water. Pour this gravy mixture over the patties and vegetables. 

** Pro Tip: For a less salty dish, use just half of the packet of au jus mix.

Step 6: Slow Cook Until Tender

Cover and cook on LOW for 3-4 hours or on HIGH for 1 1/2-2 hours. 

The patties are done when they reach an internal temperature of 160°F and the gravy is bubbling and fragrant. 

The long, slow simmer makes the beef incredibly tender and lets all those flavors meld together beautifully.

Step 7: Serve and Enjoy

Serve the patties hot with plenty of gravy spooned over the top. This is comfort food at its finest.

Variations

• Homemade Gravy Option: Instead of the canned soup shortcut, Whisk together 2 cups beef broth, 2 tablespoons Worcestershire sauce, 2 tablespoons ketchup, 1 tablespoon Dijon mustard, 1 teaspoon garlic powder, 1 teaspoon onion powder, and 1/2 teaspoon black pepper. Pour over patties and vegetables in the slow cooker. Thicken with a cornstarch slurry at the end.
• Ground Turkey or Chicken: Swap the ground beef for ground turkey or chicken if you prefer. The flavor won’t be quite as rich, but it still makes a delicious, lighter version. Just be careful not to overcook, as leaner meats can dry out more easily.
• Make It Into Meatballs: Shape the beef mixture into 1.5-inch meatballs instead of patties for a fun twist. The cooking time stays the same, and they’re perfect for serving over egg noodles or rice.
• Gluten-Free: Use gluten-free breadcrumbs or crushed gluten-free crackers, and check that your soup and gravy mixes are certified gluten-free.

What to Serve with Salisbury Steak

This rich, savory dish practically begs for something to soak up all that delicious gravy. Here are my favorite pairings:

→ Mashed potatoes are the classic choice, and for good reason. Try my sour cream mashed potatoes or this easy mashed sweet potatoes recipe for the perfect comfort food combination.

→ Egg noodles are another traditional pairing. The wide, flat noodles catch the gravy beautifully and make this feel like an old-fashioned Sunday dinner.

→ For a lighter option, serve the Salisbury steak over rice. You still get all that savory flavor without the heaviness.

→ Round out your plate with a simple green vegetable. Garlic roasted broccoli, Amish green beans, or roasted asparagus all work beautifully and add a fresh, bright contrast to the rich gravy.

→ Don’t forget a basket of 3-ingredient biscuits on the side for mopping up every last drop.

Storage, Freezing & Make Ahead

• Storage: Store leftover Salisbury steak in an airtight container in the refrigerator for up to 3-4 days. Keep the patties and gravy together so the meat stays moist.
• Reheating: Reheat gently on the stovetop over low heat or in the microwave in 30-second intervals, stirring the gravy occasionally. You can also reheat in a 325°F oven, covered with foil, for about 20 minutes.
• Freezing: This recipe freezes beautifully. Let the cooked Salisbury steak cool completely, then transfer to a freezer-safe container or heavy-duty freezer bags. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Make-Ahead: You can shape the raw patties up to 24 hours ahead and store them covered in the refrigerator. When you’re ready to cook, just brown them (if using that method) and proceed with the recipe as written.
