How to Store or Freeze This Recipe
Allow the keto tomato sauce to cool completely at room temperature before storing. This helps prevent condensation, which can lead to a watery sauce.
Transfer the cooled sauce into airtight containers or mason jars. Make sure to leave a little space at the top to allow for expansion if you plan to freeze it.
Label the containers with the date and contents. This helps you keep track of how long the sauce has been stored.
For short-term storage, place the containers in the refrigerator. The sauce will stay fresh for up to one week.
For long-term storage, place the containers in the freezer. The sauce can be frozen for up to three months without losing its flavor or texture.
When ready to use, thaw the sauce in the refrigerator overnight. If you're in a hurry, you can also thaw it in a microwave using the defrost setting.
Reheat the sauce on the stovetop over low heat, stirring occasionally to ensure even heating. You can add a splash of water or broth if the sauce has thickened too much during storage.
If you notice any changes in color, texture, or smell, it's best to discard the sauce to avoid any potential foodborne illness.
