Ingredients
- 4 thick beef chuck roast steaks, about 1.5 pounds total, tenderized
- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 tablespoon olive oil
- 2 large yellow onions, thickly sliced
- 1 ½ cups low-sodium beef broth
- 2 tablespoons soy sauce
- 1 tablespoon apple cider vinegar
- 2 tablespoons tomato paste
- 1 teaspoon dried thyme
- 2 tablespoons cornstarch
- 3 tablespoons cold water
- Fresh chopped parsley, for garnish
Prepare the Beef
Start by patting the beef steaks completely dry with paper towels. Removing excess moisture helps the steaks develop a beautiful browned crust when they hit the hot skillet.
Season both sides generously with salt, black pepper, garlic powder, and onion powder. Make sure the seasoning is spread evenly over the surface of each steak.
Sear the Steaks
Heat the olive oil in a heavy skillet over medium-high heat.
Once the skillet is hot, carefully add the seasoned steaks. Sear them for about 3–4 minutes on each side, or until a deep brown crust develops.
You do not need to cook the steaks completely at this stage. The goal is to create a flavorful browned exterior before they go into the slow cooker.
Once browned, transfer the steaks to the slow cooker and arrange them in a single layer.
Add the Onions
Slice the yellow onions into thick pieces and scatter them evenly over and around the beef.
As the steaks cook slowly, the onions will soften and absorb the savory flavors from the beef and gravy. They also add a subtle sweetness that balances the richness of the dish.
Prepare the Gravy
In a separate bowl, add the beef broth, soy sauce, apple cider vinegar, tomato paste, and dried thyme.
Whisk everything together until the mixture is smooth and well combined.
Pour the gravy mixture evenly over the steaks and onions in the slow cooker.
Slow Cook the Beef
Cover the slow cooker and cook on LOW for 6–7 hours or HIGH for 3–4 hours.
The beef should become very tender and easy to pierce with a fork. It should also reach a safe internal temperature of 165°F (74°C).
Cooking the beef slowly allows the onions and gravy to develop a deep, comforting flavor while helping the steaks become tender.
Thicken the Onion Gravy
Once the beef is tender, carefully transfer the steaks to a plate and set them aside.
In a small bowl, combine the cornstarch with cold water. Stir until completely smooth and no dry cornstarch remains.
Pour the cornstarch mixture into the slow cooker and stir it into the gravy.
Set the slow cooker to HIGH and cook for about 15 minutes, stirring occasionally, until the gravy becomes thicker and glossy.
Finish and Serve
Return the steaks to the slow cooker and spoon plenty of the thick onion gravy over the top.
Finish with freshly chopped parsley for a fresh touch and a little extra color.
Serve the Salisbury steaks immediately with your favorite side dish. Creamy mashed potatoes are especially delicious with the rich gravy, while rice or egg noodles are also excellent options.
Serving Ideas
The rich onion gravy makes this beef especially easy to pair with simple sides.
Try serving it with:
- Creamy mashed potatoes
- Steamed rice
- Egg noodles
- Roasted vegetables
- Steamed green beans
- A simple side salad
Make sure to spoon plenty of onion gravy over the beef and your chosen side. That is where much of the flavor comes together.
Helpful Tips
Pat the beef dry first.
Dry steaks brown much better in the skillet and develop a deeper crust.
Do not skip the searing step.
Although the beef will finish cooking in the slow cooker, searing it first adds extra flavor and gives the finished dish a richer taste.
Slice the onions thickly.
Thicker slices hold their shape better during the long cooking time while becoming soft and tender.
Whisk the cornstarch carefully.
Always mix cornstarch with cold water before adding it to the hot gravy. This helps create a smooth, lump-free sauce.
Let the gravy thicken before serving.
The final 15 minutes on HIGH gives the gravy time to become thick, glossy, and perfect for spooning over the steaks.
Final Thoughts
Slow Cooker Salisbury Steak with Onion Gravy is a comforting dinner that turns simple ingredients into a deeply flavorful meal. The browned beef, tender onions, and thick savory gravy come together beautifully after several hours in the slow cooker.
Serve it over mashed potatoes, rice, or egg noodles, add a little fresh parsley on top, and enjoy a warm homemade dinner that is both satisfying and easy to prepare.
