The best method, that doesn’t compromise on texture and flavor in any way is to slice it up, flash freeze it, and bag it up in freezer safe bags with the air taken out.
3. Lay all the Bread Slices Flat onto a Tray - I use an ice cube tray from my freezer, but you can use any tray that will fit on a shelf in your freezer.
5. Store your Bread in a Resealable Freezer Bag - Now that the sourdough bread is partially frozen, you can stack them together in a resealable freezer safe bag, and they won’t stick together.
6. Take out Bread Slices As and When Needed and Put Straight into the Toaster.- The slices can be taken out when needed, and put straight into the toaster from frozen.
