Ingredients For the Salisbury Steaks

1½ pounds ground beef, preferably 85% lean
½ cup breadcrumbs
1 large egg
¼ cup finely diced yellow onion
2 cloves garlic, minced
1 tablespoon Worcestershire sauce
1 teaspoon Dijon mustard
1 teaspoon Italian seasoning
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika

For the Mushroom Gravy

8 ounces mushrooms, sliced
1 medium yellow onion, thinly sliced
2 cloves garlic, minced
2 cups low-sodium beef broth
1 tablespoon Worcestershire sauce
1 tablespoon tomato paste
1 teaspoon Dijon mustard
1 teaspoon dried thyme
½ teaspoon black pepper
2 tablespoons cornstarch
3 tablespoons cold water

For Serving

Fresh chopped parsley
Mashed potatoes, egg noodles, rice, or vegetables

Step-by-Step Instructions

1. Begin by preparing the beef mixture. Add the ground beef, breadcrumbs, egg, diced onion, minced garlic, Worcestershire sauce, Dijon mustard, Italian seasoning, salt, black pepper, and paprika to a large mixing bowl.
2. Gently mix everything together with clean hands or a fork until the ingredients are evenly incorporated. Avoid overmixing, because working the meat too much can make the Salisbury steaks dense instead of tender.
3. Divide the mixture into approximately 6 equal portions. Shape each portion into an oval patty about ¾-inch thick. Press gently so the patties hold their shape without becoming too compact.
4. For extra flavor, heat a large skillet over medium-high heat and add a small amount of oil. Brown the patties for about 2–3 minutes per side. They do not need to be cooked through at this stage. This optional step creates a flavorful browned exterior and adds extra depth to the gravy.
5. Arrange the sliced mushrooms and onions across the bottom of a 5- to 6-quart slow cooker. Sprinkle the minced garlic over the vegetables.
6. Place the browned Salisbury steak patties over the mushrooms and onions, arranging them in a single layer when possible.
7. In a separate bowl, whisk together the beef broth, Worcestershire sauce, tomato paste, Dijon mustard, dried thyme, and black pepper. Pour the mixture gently around the patties.
8. Cover the slow cooker with the lid and cook on LOW for approximately 4–5 hours or until the beef patties are fully cooked and tender. Cooking time can vary depending on the slow cooker and thickness of the patties.
9. When the steaks are cooked, carefully transfer them to a plate and keep them warm. Leave the mushrooms, onions, and cooking liquid in the slow cooker.
10. To thicken the gravy, whisk together the cornstarch and cold water in a small bowl until completely smooth. Stir the slurry into the hot gravy.
11. Cover the slow cooker again and cook on HIGH for approximately 10–15 minutes, or until the gravy becomes thicker and glossy. Stir gently to distribute the thickener evenly.
12. Return the Salisbury steaks to the gravy and spoon the mushroom and onion sauce over the top. Let them sit in the gravy for several minutes so the flavors can come together.
13. Garnish with fresh chopped parsley and serve hot over mashed potatoes, egg noodles, rice, or your favorite vegetable side.

Tips & Notes

For the best texture, use ground beef that contains some fat. Very lean ground beef can produce drier patties.
Do not overmix the beef mixture. Gentle mixing keeps the Salisbury steaks soft and tender.
Browning the patties before slow cooking is optional, but it adds a deeper roasted flavor and gives the steaks a more attractive browned exterior.
Use mushrooms that are firm and fresh. White button mushrooms or cremini mushrooms both work well.
If you prefer a stronger mushroom flavor, increase the mushrooms to 12 ounces.
For an especially rich gravy, replace ½ cup of the beef broth with heavy cream near the end of cooking. Add the cream after the steaks are fully cooked and heat gently without boiling.
If the gravy is too thick, add a small amount of warm beef broth until it reaches your preferred consistency. If it is too thin, prepare a little additional cornstarch slurry and add it gradually.
Always check that the beef reaches a safe internal temperature of 160°F (71°C).

Q&A

Can I make Salisbury steak without browning the patties first?
Yes. The patties can go directly into the slow cooker. Browning is optional and mainly adds extra flavor and color.
Can I use frozen ground beef patties?
It is best to use properly thawed ground beef when forming homemade patties. This allows the ingredients to mix evenly and helps the steaks cook more consistently.
What mushrooms work best?
Cremini, baby bella, and white button mushrooms all work beautifully. You can also combine several varieties for a deeper mushroom flavor.
What should I serve with Salisbury steak?
Creamy mashed potatoes are a classic choice because they soak up the mushroom gravy. Egg noodles, rice, roasted potatoes, green beans, or steamed broccoli are also excellent options.
Can I make this recipe ahead of time?
Yes. Cooked Salisbury steak can be refrigerated in an airtight container for up to 3–4 days. Store the patties together with plenty of gravy to help maintain moisture.
Can I freeze the leftovers?
Yes. Allow the steaks and gravy to cool completely, then transfer them to freezer-safe containers. Freeze for up to about 2–3 months for best quality. Thaw overnight in the refrigerator and reheat thoroughly.
