Introduction
Honestly, Salisbury steak is one of those old-fashioned comfort foods I never get tired of. It’s hearty, savory, and incredibly satisfying, especially when the meat is simmered slowly in a rich onion gravy.
I usually make this recipe on busy days when I want dinner to be mostly hands-off. The slow cooker does all the hard work, turning simple ground beef patties into tender, flavorful steaks surrounded by caramelized onions and delicious gravy.
Serve it over mashed potatoes, egg noodles, or rice, and you have the kind of cozy dinner that makes everyone want seconds.
Ingredients
For the Salisbury Steaks
- 1½ lbs ground beef
- ½ cup breadcrumbs
- 1 large egg
- ¼ cup finely diced onion
- 2 cloves garlic, minced
- 1 tablespoon Worcestershire sauce
- 1 teaspoon Italian seasoning
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 tablespoon olive oil, for browning
For the Onion Gravy
- 2 large yellow onions, thinly sliced
- 2 cups beef broth
- 1 tablespoon Worcestershire sauce
- 1 tablespoon tomato paste
- 1 teaspoon Dijon mustard
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- 2 tablespoons cornstarch
- 3 tablespoons cold water
- 1 tablespoon butter
- Fresh parsley, chopped, for garnish
Step-by-Step Method
1. Prepare the Beef Mixture
In a large bowl, combine the ground beef, breadcrumbs, egg, diced onion, minced garlic, Worcestershire sauce, Italian seasoning, garlic powder, onion powder, salt, and black pepper.
Mix gently with your hands until everything is just combined.
Try not to overmix the beef because that can make the Salisbury steaks dense instead of tender.
2. Shape the Patties
Divide the mixture into 5–6 portions.
Shape each portion into an oval patty about ¾-inch thick.
Make the patties slightly wider than you want them to be because they will shrink a little while cooking.
3. Brown the Patties
Heat the olive oil in a large skillet over medium-high heat.
Brown the patties for about 2–3 minutes per side. They don’t need to be cooked through at this stage—the slow cooker will finish cooking them.
Transfer the browned patties to a plate.
4. Prepare the Onions
Using the same skillet, add the sliced onions.
Cook for about 4–5 minutes, stirring occasionally, until they begin to soften and lightly caramelize.
Add the butter and stir until melted.
5. Make the Gravy Mixture
In a bowl, whisk together the beef broth, Worcestershire sauce, tomato paste, Dijon mustard, garlic powder, and black pepper.
Pour the mixture into the skillet with the onions and scrape up any browned bits from the bottom. Those little browned bits add so much flavor!
6. Assemble the Slow Cooker
Place about half of the onions and gravy in the bottom of the slow cooker.
Arrange the browned Salisbury steak patties over the onions.
Pour the remaining gravy and onions over the top.
7. Slow Cook
Cover and cook on:
- LOW: 5–6 hours
- HIGH: 2½–3½ hours
The steaks should be tender and cooked through, and the gravy should be rich and flavorful.
8. Thicken the Gravy
About 15–20 minutes before serving, mix the cornstarch with cold water until smooth.
Stir the slurry into the gravy.
Cover and cook for another 15–20 minutes, until the gravy thickens.
9. Garnish and Serve
Carefully transfer the Salisbury steaks to serving plates.
Spoon plenty of onion gravy over the top and garnish with fresh chopped parsley.
Serve immediately with your favorite side dishes.
Cooking Tips
- Don’t overmix the beef. Gentle mixing keeps the patties tender.
- Brown the patties first. This adds a deeper, richer flavor to the finished dish.
- Don’t skip the onions. They become soft and sweet while cooking and make the gravy extra delicious.
- Use cold water for the cornstarch slurry. This helps prevent lumps.
- If the gravy is too thick, add a little beef broth.
- If it’s too thin, add another small amount of cornstarch slurry.
- For even more flavor, add sliced mushrooms with the onions.
Serving Suggestions
I usually serve Salisbury steak with creamy mashed potatoes because they soak up all that wonderful onion gravy.
Other delicious options include:
- Buttered egg noodles
- White rice
- Roasted potatoes
- Steamed green beans
- Roasted carrots
- Creamed corn
- Dinner rolls
- Steamed broccoli
A simple green vegetable alongside the rich gravy makes the meal feel perfectly balanced.
Make-Ahead Instructions
You can prepare the beef patties the night before and keep them covered in the refrigerator.
You can also assemble the slow cooker ingredients several hours ahead and refrigerate them until you’re ready to cook. For food safety, don’t leave raw meat sitting at room temperature.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
Reheat gently on the stovetop or in the microwave until heated through. Add a splash of beef broth if the gravy becomes too thick.
The Salisbury steak can also be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions
1. Can I make Salisbury steak without browning the patties first?
Yes, you can place the raw patties directly into the slow cooker, but browning them first gives the dish much better flavor and color.
2. Can I add mushrooms?
Absolutely! Sliced mushrooms are delicious with Salisbury steak. Add them along with the onions before slow cooking.
3. Why is my gravy too thin?
Slow cookers don’t allow much liquid to evaporate. A cornstarch slurry added near the end of cooking is an easy way to thicken the gravy.
4. Can I use ground turkey instead of beef?
Yes. Ground turkey can be substituted, although the flavor will be lighter. Make sure the turkey reaches a safe internal temperature before serving.
5. What is the best side dish for Salisbury steak?
Mashed potatoes are my top choice because they pair perfectly with the rich onion gravy. Egg noodles and rice are also excellent options.
