Yes! Make sure to let it cool completely, then wrap it really well and place in a freezer safe bag or container. I recommend enjoying your artisan bread within 3-6 months for best flavor. You can also slice the bread before freezing it to easily defrost one slice at a time (if I do this I usually individually wrap each slice to help ward off freezer burn). To thaw, let the bread sit on the counter for a few hours to thaw, or toast individual slices in the toaster. You can also warm up in a 350F preheated oven for a few (about ten) minutes.
