Be careful not to over mix your meatballs, which change the texture of them. You want them soft and juicy!
When you roll the meatballs, don't pack them too tight! Grab some of the mixture and lightly pat and roll it in your hands just until the meatball holds together. That way your meatballs won't be too dense.
When you brown the meatballs don't cook them all the way through because they will finish cooking in the sauce. Overcooked meatballs can be too dry, so only brown them for a few minutes.
To save even more time feel free to substitute frozen meatballs instead of making your own homemade meatballs.
If you have a favorite homemade marinara sauce you should use it! If you have a favorite homemade spaghetti sauce use that!
