Yes, you can freeze a puff pastry pull apart bread.  Just make sure to wrap it tightly in plastic wrap or aluminum foil. When you're ready to eat it, thaw the bread in the refrigerator overnight and then reheat it in a 350-degree oven for about 10 minutes. This is good for around 3 months if stored properly in the freezer. Make sure the bag or container is labeled with the recipe name and date made so you know how long it is still good in your freezer.
