Common Mistakes to Avoid

Boldly overcooking onions: Cooking onions too quickly can lead to uneven caramelization. Take your time and cook them slowly for 20–25 minutes until golden brown.
Boldly skimping on seasoning: Not adding enough salt and pepper can result in bland potatoes. Taste your mixture before layering it, and adjust the seasoning as necessary.
Boldly using the wrong potatoes: Choosing waxy potatoes instead of starchy ones like Yukon Gold or Russet may affect texture. Opt for the right type for a creamy consistency.
Boldly overcrowding the baking dish: Layering too many potatoes can cause uneven cooking. Ensure there’s enough space for heat to circulate by using an appropriately sized dish.
Boldly skipping the resting time: Cutting into the casserole immediately after baking can lead to a messy serving. Let it rest for 5–10 minutes before serving to set properly.
