Common Mistakes to Avoid
When making Sweet Potato Kale Gratin, it’s easy to overlook some details that can affect the final outcome. Here are some common mistakes and how to avoid them.
- Ignoring the thickness of slices: If your sweet potato slices are too thick, they won’t cook evenly. Aim for about 1/8 inch thickness for perfect layering.
- Overcooking the kale: Sautéing kale for too long can make it mushy and lose its vibrant color. Cook it just until wilted for the best texture and flavor.
- Skipping the seasoning: Not adding enough salt and pepper can lead to bland flavors in your gratin. Season each layer as you build the dish for a well-balanced taste.
- Using low-quality cheese: Opting for a lower quality cheese can result in less flavor and creaminess. Choose a good-quality Gruyère or a similar cheese for optimal results.
- Not letting it rest: Cutting into the gratin immediately after baking can cause it to fall apart. Allow it to cool for 10 minutes before serving to set properly.
