If you don’t know, a make-ahead freezer meal is one where you prep the work ahead of time, freeze it in a bag for later, and then thaw and cook later (a few days…a few weeks…or a few months later.

To make this recipe ahead of time, you’ll just need a few freezer meal tools. The main thing you’re going to need to make this ahead of time is something to store your uncooked meal in. I use these compostable freezer bags because I don’t love the idea of using single-use plastic bags.

Here’s the general idea:

  • Prep your ingredients
  • Put them in your (labeled) freezer bag
  • Freeze for later

To make this slow cooker spaghetti and meatballs, just set the bag it in the fridge the night before you’re ready for it.
