Common Mistakes to Avoid

To create the perfect sweet potato gratin, avoid these common mistakes.

• Using unevenly sliced potatoes: If your sweet potatoes are not sliced evenly, they will cook at different rates. Use a mandoline or sharp knife to achieve uniform thickness.
• Skipping the seasoning: Sweet potatoes need flavor! Don’t forget to season your cream mixture adequately with salt, pepper, and nutmeg for a well-rounded taste.
• Overcrowding the baking dish: Layering too many sweet potatoes can lead to uneven cooking. Stick to the recommended layers for optimal results.
• Not letting it cool: Cutting into your gratin immediately after baking can cause it to fall apart. Allow it to cool for five minutes before serving for better presentation.
• Using low-quality cheese: The cheese is key in this dish. Choose high-quality Gruyère or sharp cheddar for a richer flavor and creaminess.
