FAQs
Can I use homemade meatballs instead of frozen?
Yes, homemade meatballs work great. Just brown them first for better texture and then proceed with the recipe.
Can I make this recipe without a Crock-Pot?
You can cook the meatballs and sauce on the stovetop in a covered pan over low heat until heated through, but slow cooking helps develop deeper flavors and tender meatballs.
