Common Mistakes to Avoid
Making French Onion Potatoes can be simple, but a few common mistakes can affect the final dish. Here are some pitfalls to avoid.
- Skipping the potato prep: Not peeling or slicing the potatoes thinly can lead to uneven cooking. Ensure you peel and slice them uniformly for consistent results.
- Ignoring seasoning: Failing to add enough salt and pepper can make your dish bland. Taste as you go and adjust seasoning for maximum flavor.
- Overcrowding the baking dish: Filling the dish too full can result in uneven cooking. Make sure there’s enough space for the heat to circulate around the potatoes.
