Refrigerate. You can store this hearty bolognese in an airtight container in the refrigerator for 3-4 days. This is actually better if you make it the day before, because it gives all of the flavors a chance to combine.  Freeze. This freezes really well, so you can make it ahead of time and take it out for busy weeknights. Store in an airtight container in the freezer for 2-3 months. Move to the refrigerator the night before to defrost, and reheat in a skillet over medium heat.
