Do I need to boil the potatoes first?
No. Red potatoes roast beautifully without parboiling, especially when you use a hot oven, enough oil, and don’t crowd the pan. That said, crispiness can vary a bit depending on how fresh and moist your potatoes are and how evenly you cut them. If you want an extra-crispy finish, you can soak the cut potatoes in cold water for 20 minutes, then dry them very well before roasting. If you want the most reliably rugged, craggy edges, a quick parboil and rough-up will do it, but it is optional.
Why are my roasted potatoes not crispy?
Usually one of these: the pan is crowded, the potatoes were not dried well, the oven temp is too low, or you did not use enough oil. Also, parchment is convenient but can reduce browning. For maximum crisp, roast directly on a lightly oiled metal sheet pan.
What temperature is best for roasting red potatoes?
450°F is my sweet spot for crisp edges and good color. If your oven runs hot or smokes, drop to 425°F and add a few minutes. If you are using convection, reduce the temp by about 25°F and start checking a little earlier.
Can I use fresh herbs instead of dried?
Yes. Dried herbs are great for roasting because they cling and toast a bit. If using fresh, add most of them at the end so they stay bright. Rosemary and thyme can handle heat better than delicate herbs like parsley.
How small should I cut the potatoes?
Aim for 1-inch pieces. That size gives you enough surface area for crisping while keeping the center tender.
