Storage Tips
The Spaghetti Squash Bolognese Recipe can be stored in the fridge for up to 3-4 days in an airtight container. To freeze the bolognese, let it cool down completely and transfer it into a freezer-safe container or a ziplock bag. It can be stored in the freezer for up to 2-3 months.
To defrost the frozen bolognese, simply transfer it into the fridge and let it defrost overnight. Alternatively, you can transfer the frozen bolognese into a microwave-safe dish and defrost it on low heat, stirring occasionally.
When reheating the bolognese, you can either microwave it on high heat for 1-2 minutes, stirring occasionally, or warm it up in a saucepan over medium heat.
To store the spaghetti squash, keep it whole in a cool, dry place for up to 1-2 months. Once cut, wrap the squash tightly in plastic wrap and store it in the fridge for up to 1 week.
