Though not exactly good for the waistline, croissants are a delectable French pastry treat. The key to including flaky, rich buttery treats, such as croissants, into your meal plan is to eat them in moderation, making them a once-in-a-while indulgence rather than something you would consume every day. Purchasing frozen croissants is a convenient way to have the pastry on hand for those days that a treat is in order.
Remove the croissant from the freezer and place it on a plate on the counter; allow it to thaw for at least a half-hour before cooking it.
Preheat your oven to 350 degrees Fahrenheit.
Place the croissant on a baking sheet and put it into the heated oven.
Cook the croissant for 12 to 15 minutes, or until the outside is a light-golden brown color.
Remove the croissant from the oven when it is finished cooking. Transfer the croissant to a plate so that the bottom does not burn from remaining on the baking sheet, and allow it to cool for a minute or two before eating it.
