Frequently asked questions
Yes, but it won't get quite as crispy. Roast it straight from frozen at 450°F and expect it to release more moisture. It will still be delicious, just softer.
Use freshly grated Parmesan and don't roast it too long. Make sure to add the Parmesan during the last 30 minutes of roasting.
Nope, roasting it raw is the best way to keep it flavorful and crispy edges. Boiling will make it mushy!
