Main Ingredients

  • 1 bag frozen meatballs No need to thaw.
  • 2 cans French onion soup Can use any brand.
  • 1 cup beef broth Substitute with chicken broth if desired.
  • 1 cup shredded mozzarella cheese Can substitute with provolone or cheddar.
  • 1 tsp Worcestershire sauce For added flavor.
  • 1 tbsp butter Use unsalted for better control over seasoning.

Instructions
 

Preparation

  • Place frozen meatballs into the slow cooker.
  • Pour in the French onion soup and beef broth over the meatballs.
  • Add Worcestershire sauce and butter; stir gently to combine.

Cooking

  • Cook on low for 5-6 hours, or until heated through and the flavors meld together.
  • About 15 minutes before serving, sprinkle mozzarella cheese on top to melt.

Serving

  • Serve warm with crusty bread or mashed potatoes.
  • For a fun twist, create meatball subs using a soft baguette.

Notes

Leftover meatballs can be stored in an airtight container in the fridge for up to three days. Reheat in the microwave, stovetop, or oven for crispy texture. Experiment with different cheese or add fresh herbs for variety.
