Frequently Asked Questions
Q: Can I prepare these vegetables ahead of time?
A: Yes! You can cut all vegetables up to 24 hours in advance. Store them separately in airtight containers in the refrigerator. The potatoes should be submerged in cold water to prevent browning.
Q: Why aren’t my vegetables getting crispy?
A: The most common causes are overcrowding the pan or using too much oil. Make sure vegetables have plenty of space and follow the recommended oil amount.
Q: Can I use dried herbs instead of fresh?
A: While fresh herbs provide the best flavor, you can use dried herbs in a pinch. Use one-third of the amount called for fresh herbs, as dried herbs are more concentrated.
Q: How do I know when the vegetables are done?
A: Potatoes and carrots should be easily pierced with a fork but still hold their shape. Zucchini should be tender but not mushy.
Q: Can I make this recipe for a larger crowd?
A: Absolutely! Double or triple the recipe, but use multiple baking sheets to avoid overcrowding. Rotate the pans’ positions halfway through cooking.
