Slow Cooker Salisbury Steak Meatballs are juicy beef meatballs simmered in a rich mushroom and onion gravy — a classic, hearty meal perfect for family dinners.
For the Meatballs:
1½ lbs ground beef (80–85% lean)
½ cup breadcrumbs
1 egg
¼ cup grated onion
2 garlic cloves, minced
1 tbsp Worcestershire sauce
1 tbsp parsley, chopped
1 tsp salt
½ tsp pepper
For the Gravy:
1 onion, thinly sliced
8 oz mushrooms, sliced
2 cups beef broth
2 tbsp Worcestershire sauce
2 tbsp ketchup
½ tsp garlic powder
½ tsp onion powder
Salt & pepper to taste
2 tbsp cornstarch + 3 tbsp water (slurry)
Mix meatball ingredients and form 1½-inch balls. Brown in a skillet if desired.
Add sliced onions and mushrooms to the bottom of the slow cooker. Place meatballs on top.
Whisk gravy ingredients and pour over meatballs.
Cook on LOW 5–6 hours or HIGH 3–4 hours.
In the last 30 mins, stir in cornstarch slurry to thicken gravy.
Serve over mashed potatoes, noodles, or rice. Garnish with parsley.
Use frozen meatballs for a shortcut. Add peas or carrots for extra veggies.
