I often freeze leftover bakery bought baguettes.
I wrap the tightly in plastic wrap then into a ziplock.
The trick is defrosting them. Wrap a loaf or part of a loaf in dampened paper towels and microwave on high until just heated through. For a partial baguette, which is quite thin, I can get that done in 20-30 seconds. Then you can slice and enjoy. It's not perfect but better than no bread at all.
