- Skipping the roasting of garlic – Roasting garlic brings out its sweetness and depth of flavor. Always roast the garlic before adding it to the potatoes.
- Not drying the potatoes – If you skip steaming the boiled potatoes, they can become watery. Ensure you let them dry in a colander for a few minutes after draining.

- Ignoring seasoning – Failing to season adequately can lead to bland duchess potatoes. Taste and adjust salt and pepper as needed.
