Common Mistakes to Avoid
When making French Onion Potatoes, it’s easy to overlook some details that can impact the final dish. Here are common mistakes to avoid.

- Ignoring Seasoning: Failing to add salt and pepper can dull the flavor. Always season the layers and the sour cream mixture for a tastier result.
- Not Preheating the Oven: Baking in a cold oven can affect cooking time and texture. Always preheat your oven before putting in your dish.
- Overcrowding the Dish: Packing too many potatoes into one dish may cause them to cook unevenly. Use a larger baking dish if needed.
- Lifting the Foil Too Early: Removing the foil too soon can dry out the potatoes. Wait until they are nearly tender before uncovering them.
