- Choose the right potatoes: Use starchy potatoes like yellow or russet for optimal fluffiness.
- Dry thoroughly: After boiling, make sure your potatoes are completely dry before roasting for maximum crispiness.

- Don’t overcrowd the pan: Give each potato space to roast evenly; this helps achieve that golden brown finish.

Common Mistakes to Avoid
Crispy Roast Potatoes with Rosemary and Garlic – Whole30 can be a delightful side dish, but avoid these common mistakes for the best results.
- Skipping the soaking step: Not rinsing the potatoes can lead to less crispy results. Rinse them under cold water to remove excess starch.
- Overcrowding the pan: If you pile too many potatoes in the roasting pan, they will steam instead of roast. Spread them out in a single layer for optimal crispiness.
- Ignoring temperature: Cooking at a lower temperature won’t yield that desired golden brown crust. Ensure your oven is preheated to 450F for perfect roast potatoes.
- Not shaking the colander: Failing to rough up the edges of the potatoes can make them less crispy. Gently shake them in the colander after draining for better texture.
- Under-seasoning: Skipping seasoning can leave your potatoes bland. Be sure to season them well before roasting and adjust as needed after cooking.
