What Are Salisbury Steak Meatballs?

Salisbury Steak Meatballs are a fun and flavorful twist on the traditional Salisbury steak. Instead of pan-frying hamburger patties, ground beef is rolled into juicy meatballs and slow-cooked in a savory onion-mushroom brown gravy. The meatballs soak up the sauce as they simmer, resulting in a tender, flavorful bite every time.

They’re typically served over mashed potatoes, egg noodles, or rice, with that rich gravy ladled on top. Think of it as your favorite TV dinner reimagined homemade, hearty, and way more delicious.

How to Make Slow Cooker Salisbury Steak Meatballs

1. Make the meatballs: In a large bowl, combine beef, breadcrumbs, egg, ketchup, Worcestershire, onion powder, garlic powder, salt, and pepper. Mix just until combined.
2. Form into meatballs (about 1 ½ inches wide). Optional: Brown them in a skillet for 2–3 minutes to seal in flavor.
3. Layer the sliced onions in the bottom of your slow cooker.
4. Place meatballs on top of the onions.
5. Mix the gravy: In a bowl, whisk together mushroom soup, beef broth, and Worcestershire.
6. Pour the gravy over the meatballs, covering them completely.
7. Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours.
8. Optional: In the last 20 minutes, stir in a cornstarch slurry to thicken the gravy.
9. Garnish and serve over mashed potatoes, noodles, or rice.

What to Serve With Salisbury Steak Meatballs

• Creamy mashed potatoes
• Buttered egg noodles
• Garlic green beans
• Roasted carrots
• Dinner rolls or biscuits
• A crisp side salad

The gravy pairs beautifully with soft sides that can soak up every last drop.

Tips for Success

• Don’t overmix the meat—just until combined for tender meatballs.
• Brown for flavor: While optional, searing adds great depth.
• Layer onions first so they caramelize and protect meatballs from sticking.
• Check seasoning before serving and adjust salt/pepper if needed.
• Thicken if desired with cornstarch slurry near the end.

Common Mistakes to Avoid

• Overcooking: Stick to recommended times for juicy meatballs.
• Using very lean beef: A little fat keeps the meatballs moist.
• Too much mixing: Can make the meatballs tough.
• Forgetting to layer onions: They add flavor and prevent sticking.
• Not thickening the sauce (if preferred): Some like it heartier!

How to Store & Reheat

• Fridge: Store in an airtight container for up to 4 days.
• Freezer: Freeze in a freezer-safe bag or container for up to 2 months.
• Reheat: Warm on the stove or microwave with a splash of broth if needed.

Great for batch cooking or make-ahead meals!
