Slow Cooker Salisbury Steak
This slow cooker Salisbury steak is the ultimate “set it and forget it” comfort meal. Unlike the frozen versions you might recall, this recipe uses onion soup mix in the patties and a rich au jus gravy that develops deep, savory flavor after hours of slow cooking. Coating the patties lightly in flour before searing is the key step—it gives the meat a better texture and naturally thickens the gravy into a silky sauce as it simmers.
Ingredients
2 lbs lean ground beef
½ cup breadcrumbs
¼ cup milk
1 (1 oz) packet onion soup mix
½ teaspoon dried thyme
¼ cup all-purpose flour
2 tablespoons extra virgin olive oil
1 white onion, sliced
2 (10 oz) cans condensed cream of chicken soup
¾ cup water
1 (1 oz) packet au jus mix
Instructions
Step 1: Make the Patties
In a large bowl, combine the ground beef, breadcrumbs, milk, onion soup mix, and thyme. Mix gently with your hands until just combined. Shape the mixture into 8 equal, oval patties.
Step 2: Prep the Slow Cooker
Arrange the sliced onions in the bottom of the slow cooker. This acts as a base for the patties and infuses the gravy with sweet onion flavor.
Step 3: Sear the Patties
Heat the olive oil in a skillet over medium-high heat. Lightly coat each patty in flour, shaking off any excess. Brown the patties for about 3–4 minutes per side.
Step 4: Layer and Add Gravy
Place the browned patties on top of the onions in the slow cooker. In a bowl, whisk together the condensed soup, water, and au jus mix. Pour the mixture over the patties.
Step 5: Slow Cook
Cover and cook on Low for 4–5 hours. The patties will become tender, and the onions will melt into the savory, flavorful gravy.
