No — but yes. I know not everyone has the time to make homemade spaghetti sauce and homemade meatballs on the same night. If you're in a pinch, frozen meatballs will get the job done. But... they're not as good. When you make your own meatballs you control the most important variable of meatballs: bread. Meatballs usually have some sort of breading in them, whether it’s literally bits of bread or some sort of breadcrumbs. I personally don't trust food companies making frozen meatballs to a) use quality meat and b) not cut corners by using more bread than meat. And I like a meatier meatball anyway. So I make them from scratch. If you don't have time to make meatballs AND sauce from scratch on the same night, you can always make the meatballs ahead of time. Fully cooked, they'll stay good in the fridge for 3-5 days and in the freezer up to 3 months.
