Zusatztipps für die Zubereitung

For extra crispiness, soak your cut potatoes in cold water for 30 minutes, then dry them thoroughly before baking. This helps remove excess starch, ensuring a better crunch. Always make sure to line your baking sheet with parchment paper to prevent the potatoes from sticking.

Varianten und Anpassungen

You can easily customize these fries by swapping fresh parsley for other herbs like chives or thyme. For a dairy-free version, use vegan butter or simply replace the butter with olive oil to maintain a rich, savory coating.
