Slow Cooker Salisbury Steak Meatballs — See Me Cook the Easiest Crockpot Dinner

Slow cooker Salisbury steak meatballs in mushroom gravy over mashed potatoes crockpot dinner Save

Watch me make these Slow Cooker Salisbury Steak Meatballs — tender beef meatballs smothered in the richest mushroom gravy you’ve ever tasted, completely hands-off in the crockpot. I dump everything in before I leave the house and come home to a dinner that tastes like I spent all afternoon cooking!

Why I Keep Making This

  • 5 minutes of prep then the crockpot does everything
  • Mushroom gravy is so rich and glossy it’s almost unbelievable
  • Meatballs turn impossibly tender slow-cooked in gravy all day
  • Perfect for feeding a hungry family of 6
  • Freezes in batches — dinner sorted for the whole month

Ingredients

For the Meatballs

  • 2 lbs (900g) ground beef 80/20
  • ½ cup plain breadcrumbs
  • 1 large egg
  • 2 tbsp Worcestershire sauce
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp salt
  • ½ tsp black pepper

For the Mushroom Gravy

  • 2 cans (10.5 oz each) cream of mushroom soup
  • 1 packet (1 oz) onion soup mix
  • 1½ cups beef broth
  • 8 oz sliced cremini mushrooms
  • 2 tbsp Worcestershire sauce
  • 1 tsp garlic powder

Watch Me Cook It — Step by Step

  1. Mix the meatballs gently — combine all meatball ingredients by hand just until mixed. Overworking makes them tough. Roll into 1.5-inch balls.
  2. Optional sear (worth it): Brown meatballs in a hot skillet 2 minutes per side. This builds a flavor foundation the slow cooker can’t create alone.
  3. Build the gravy: Whisk together both cans of soup, broth, onion soup mix, Worcestershire, and garlic powder until smooth.
  4. Layer in crockpot: pour in half the gravy, nestle in all the meatballs, scatter mushrooms over top, pour remaining gravy over everything.
  5. Cook LOW 6–8 hours or HIGH 3–4 hours. Thicken if you like: stir in 2 tbsp cornstarch dissolved in 2 tbsp cold water during the last 30 minutes.

My tip: Do not stir the first few hours — let the meatballs set up so they hold their shape. Once they’re cooked through you can gently stir the gravy.

FAQ

Can I use frozen meatballs?

Absolutely — use 2 lbs of your favorite frozen Italian-style meatballs straight from the freezer. Skip the mixing entirely and add 1 hour to the LOW cook time.

How do I thicken the gravy?

Mix 2 tablespoons cornstarch with 2 tablespoons cold water and stir it into the crockpot in the last 30 minutes with the lid off on HIGH. Stir every 10 minutes until it reaches your preferred consistency.

✅ Pro Tips for Perfect Results

  • Don’t skip the sear: Two minutes per side in a hot skillet before the crockpot adds color and fond that the slow cooker simply cannot replicate on its own.
  • Mix gently, always: Over-worked ground beef makes rubbery, dense meatballs. Mix just until the ingredients come together — stop immediately.
  • 1.5-inch rule: Slightly larger meatballs hold up better to long slow-cooker cooking without falling apart. Use an ice cream scoop for consistency.
  • Don’t lift the lid: Every peek costs 20–30 minutes of cooking time. Trust the process.
  • Make-ahead trick: Roll meatballs the night before, refrigerate on a parchment-lined tray, then transfer straight to the crockpot in the morning.

🔄 Variations & Customizations

  • Swedish Style: Swap mushroom soup for cream of chicken, add ¼ tsp nutmeg and ¼ tsp allspice to meatballs
  • French Onion Version: Replace onion soup mix with caramelized onions + 1 tsp beef bouillon
  • Italian Twist: Add 2 tbsp grated Parmesan to the meatball mix, use Italian seasoning instead of onion powder
  • Turkey Meatballs: Lean ground turkey works great — add 1 tbsp olive oil to the mix to compensate for the lower fat
  • Cheesy Finish: Stir in ½ cup cream cheese in the last 30 minutes for an incredibly rich, velvety sauce
  • Slow Cooker Stroganoff: Stir in 1 cup sour cream right before serving and serve over egg noodles
