Tips & Variations

  • Gently mix ingredients to avoid tough meatballs; avoid overworking the meat.
  • Add a splash of Worcestershire sauce to the meat mixture for extra depth.
  • Let meatballs rest 10 minutes after shaping before cooking to hold their shape better.
  • Mix in fresh herbs like parsley or thyme for a bright, fresh twist.
  • For some heat, add red pepper flakes with the salt and pepper.
  • Try smoked paprika or hot sauce for smoky or spicy variations.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop until warmed through. For longer storage, freeze meatballs and broth separately in freezer-safe containers for up to 3 months; thaw overnight in the fridge before reheating.

FAQs

Can I use ground turkey or chicken instead of beef?

Yes, ground turkey or chicken can be used, but they tend to be leaner and may need a bit of added moisture or fat (like a little olive oil) to keep the meatballs juicy.

Do I need to brown the meatballs before adding them to the crockpot?

No, browning is not necessary for this recipe. The meatballs cook slowly in the flavorful broth, which keeps them tender and infuses them with great flavor.
