Absolutely! Freezing focaccia is a great way to keep it fresh for later. Just let your focaccia cool down after baking, then wrap it snugly in plastic wrap or aluminum foil. You can also pop it into a freezer bag. It'll stay good in the freezer for about three months. When you're just storing it for a day or two, keep your focaccia in an airtight container or wrap it up well to keep it fresh. You can also pop it in the fridge where it'll last about a week, though it might get a bit firmer. Just remember to warm it up a bit (about 10-15 mins in a 200F oven) before eating — it brings back some of that freshly-baked magic!
