Common Mistakes to Avoid
When making Sweet Potato Kale Gratin, it’s essential to avoid common pitfalls that can affect the dish’s flavor and texture. Here are some mistakes to keep in mind:
- Using thick sweet potato slices: Thick slices can result in uneven cooking. Slice your sweet potatoes thinly for even baking and a better texture.

- Not seasoning properly: Under-seasoning can make your gratin bland. Use salt and pepper generously to enhance the flavors of the sweet potatoes and kale.
- Covering too long while baking: Leaving the foil on for the entire baking time prevents browning. Remove it halfway through to allow for a golden, crispy top.
- Neglecting resting time: Cutting into the gratin immediately can cause it to fall apart. Let it cool for about 10 minutes before serving to set properly.
