FAQs
Q: Can I use ground turkey instead of beef?
A: Yes. Ground turkey works but it is leaner. Add a little oil or extra breadcrumbs for texture.
Q: Do I need to brown the meatballs first?
A: No, but browning adds color and helps them hold together. You can skip it to save time.
Q: Can I make this on high for less time?
A: Yes. Cook on high for about 3 hours instead of 6 hours on low.
Q: How do I make the sauce thicker?
A: Mix 1 tablespoon of cornstarch with 2 tablespoons cold water and stir into the slow cooker. Cook 15-30 minutes more.
Q: Can I freeze the meatballs in sauce?
A: Yes. Cool completely, then freeze in a tight container. Thaw in the fridge before reheating.
