Frequently Asked Questions
Fresh green beans are strongly recommended for this recipe as they roast up with the best texture and those beautiful crispy edges that make this dish so good. Frozen green beans tend to release too much moisture in the oven which can make them steam rather than roast, resulting in a softer and less flavorful result. Fresh green beans will give you the best outcome every time.
The key to perfectly crispy oven roasted green beans is making sure they are completely dry before they go on the baking sheet. Pat them thoroughly with a paper towel after washing.
These green beans are best enjoyed fresh out of the oven when the parmesan crust is at its crispiest and most delicious. If you do need to make them ahead you can prep and trim the green beans in advance and store them in the refrigerator until you are ready to roast. Leftovers can be stored in an airtight container in the refrigerator for up to three days and reheated in the oven or air fryer to bring back some of that crispiness.
