Step-by-Step Instructions
1. Prepare the Beef Mixture
In a large bowl, combine breadcrumbs and milk.
Let them sit for about 2–3 minutes.
Add ground beef, egg, grated onion, garlic, Worcestershire sauce, ketchup, Dijon mustard, garlic powder, onion powder, paprika, salt, and black pepper.
Mix gently until just combined.
Avoid overworking the beef so the finished patties stay tender.
2. Shape the Meat
Divide the beef mixture into approximately 8 portions.
Shape each portion into a thick oval patty or large meatball.
Try to keep them similar in size so they cook evenly.
3. Brown the Beef
Heat olive oil in a large skillet over medium-high heat.
Working in batches, sear the beef patties for approximately 2 minutes per side.
You only need to brown the outside—the centers will finish cooking in the slow cooker.
Transfer the browned beef to a plate.
4. Prepare the Slow Cooker
Arrange the baby potatoes across the bottom of the slow cooker.
Scatter the sliced onions around the potatoes.
Season lightly with salt and black pepper.
Place the browned Salisbury steak patties over the vegetables.
5. Make the Gravy
In a bowl, whisk together beef broth, Worcestershire sauce, soy sauce, tomato paste, Dijon mustard, thyme, garlic powder, onion powder, and black pepper.
Pour the mixture evenly over the beef, potatoes, and onions.
Dot the top with butter.
6. Slow Cook
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours.
For the most tender meat and flavorful gravy, LOW is recommended.
The potatoes should become completely fork-tender and the beef should reach at least 160°F (71°C) internally.
7. Thicken the Onion Gravy
Carefully transfer the beef patties and potatoes to a serving platter if desired.
Mix cornstarch and cold water together until completely smooth.
Stir the slurry into the hot cooking liquid.
Cover and cook on HIGH for another 10–15 minutes, until the gravy becomes thick and glossy.
8. Finish the Dish
Return the beef and potatoes to the slow cooker.
Gently spoon the thick onion gravy over everything.
Let the dish sit for another 5 minutes so the flavors come together.
9. Serve
Arrange the Salisbury steak meatballs or patties with baby potatoes and softened onions on serving plates.
Spoon plenty of hot brown gravy over each portion.
Finish with fresh parsley, thyme, and cracked black pepper.
Cooking Tips
- Use ground beef with some fat for juicier Salisbury steak patties.
- Do not overmix the beef mixture or the meat can become dense.
- Browning the meat before slow cooking creates deeper flavor.
- Keep smaller baby potatoes whole and halve larger ones for even cooking.
- Slice the onions fairly thick so they hold some texture during the long cooking time.
- If the gravy becomes too thick, loosen it with a little additional beef broth.
Serving Suggestions
Serve this slow cooker Salisbury steak dinner with:
- Garlic green beans
- Buttered peas
- Roasted carrots
- Steamed broccoli
- Warm dinner rolls
- Fresh garden salad
The baby potatoes already make it a complete hearty meal, so only a simple vegetable side is needed.
Storage
Store leftover beef, potatoes, onions, and gravy together in an airtight container in the refrigerator for up to 4 days.
Reheat gently in a covered saucepan or skillet over medium-low heat.
Add a splash of beef broth if the gravy becomes too thick after refrigeration.
Leftover Ideas
- Mash leftover potatoes and serve the beef and gravy over them.
- Break up the beef and turn leftovers into a hearty beef-and-potato skillet.
- Serve sliced patties inside toasted rolls with caramelized onions.
- Spoon leftovers over egg noodles for an easy second dinner.
FAQs
Can I use ground turkey instead of beef?
Yes. Ground turkey works, although the finished dish will have a lighter flavor. Avoid using extremely lean turkey so the patties stay juicy.
Can I add mushrooms?
Absolutely. Add about 8 oz sliced mushrooms with the onions for an even richer Salisbury steak gravy.
Do I have to brown the meat first?
No, but browning adds considerably more flavor and helps the patties hold their shape.
Can I use larger potatoes?
Yes. Cut Yukon Gold or red potatoes into approximately 1½-inch chunks.
Can I prepare this ahead of time?
Yes. Shape and brown the beef patties the night before and refrigerate them. Assemble everything in the slow cooker when ready to cook.
