Absolutely! Meat sauce is one of the best things to make ahead and freeze for later. Simply put the cooled sauce into large mason jars or gallon size freezer storage bags, close securely and freeze for up to 3 months. I find that using a large ladle or 1-cup measuring cup works well to transfer the sauce into the jars or bags. Lay bags flat to freeze so they can be stacked if necessary. Let thaw in the fridge overnight and then reheat to serve.
