FAQ

Can I prepare the seasoning mix ahead of time?

Yes, combine all dry and wet spices in a bowl and refrigerate up to 3 days. Add potatoes and toss just before roasting.

What if my potatoes are unevenly sized?

Cut larger spears thinner so all pieces finish cooking simultaneously. Alternatively, add smaller pieces to the pan halfway through baking.

How long can I keep these and can I reheat them?

Store 4 days refrigerated. Reheat on a baking sheet at 350F for 8-10 minutes to restore crispness, or serve cold.
