Common Mistakes to Avoid

Overcooking or undercooking – Baking times are crucial for tender potatoes. Make sure to bake until they are fork-tender, adjusting time as needed based on your oven.
Neglecting seasoning – Failing to season properly can leave your dish bland. Taste and adjust salt and pepper before serving.
