Common Mistakes to Avoid

To make the most out of your Sweet Potato Gratin with Smoked Gouda and Rosemary, it’s important to steer clear of common pitfalls.

• Incorrect Potato Thickness: Slicing the sweet potatoes too thick will result in uneven cooking. Aim for uniform 1/8” rounds for the best texture.
• Skipping the Cooling Step: Not allowing your sauce to cool before mixing with the potatoes can lead to a soupy gratin. Take the time to let it cool to room temperature.
• Overbaking: Baking for too long can dry out the gratin. Keep an eye on it, especially during the last minutes, to achieve that perfect golden brown top without losing moisture.
• Neglecting Seasoning: Under-seasoning can leave your gratin bland. Be sure to taste and adjust your spices before baking for maximum flavor impact.
• Using Low-Quality Cheese: Using pre-shredded cheese may contain anti-caking agents that prevent melting properly. Opt for freshly shredded cheese for a creamier result.
