Common Mistakes to Avoid

- Ignoring the preheating step: Skipping the preheating of the roasting pan means your potatoes won’t start cooking properly. Always preheat your pan with fat before adding the potatoes.
- Under-seasoning: Not seasoning adequately can result in bland potatoes. Don’t be shy; season generously with salt and pepper throughout the cooking process.
- Skipping the garlic: The roasted garlic adds wonderful flavor, so don’t leave it out! Make sure to include it in your roasting for an extra depth of taste.
