If you want to make these glazed carrots ahead of time, I’d suggest doing so a maximum of 2 days prior and storing them in your refrigerator in an airtight container. They can then be heated up in the oven or in your microwave. I wouldn’t recommend keeping these honey glazed carrots for any longer than 2 days in the refrigerator (and certainly not to be stored in your freezer) as they are likely to become soft and mushy after an extended period of storage or through thawing if frozen.
