# Expert Hints:

01 -
  • Ready in 40 minutes start to finish, which means you can make them even on busy nights when cooking feels impossible.
  • The edges get crispy while the insides stay buttery soft, giving you that textural contrast that makes every bite interesting.
  • Cajun seasoning does all the heavy lifting so you're not standing there wondering what flavors work together.
02 -
  • Don't overcrowd your baking sheet or they'll steam instead of roast, and you'll miss out on those crucial crispy edges that make them special.
  • The flip at the 15-minute mark is non-negotiable because it ensures both sides get that caramelization and color.
  • If your oven runs hot or cool, keep an eye on them during the second half of cooking since every oven has its own personality.
03 -
  • Keep the potato slices consistent in thickness so they all finish cooking at the same time and you don't end up with some crispy and some still soft.
  • If your potatoes are particularly large, use a mandoline or sharp knife to get uniform slices, which also speeds up the whole process.
