Instructions

Step 1

Zusatztipps für die Zubereitung

To ensure the best results, use a large baking sheet to avoid overcrowding the fries, which can lead to steaming instead of crisping. Using a spatula to flip the fries halfway through the cooking time will help them brown evenly on all sides.

Varianten und Anpassungen

You can easily customize the flavor by swapping fresh parsley for other herbs like chives or thyme. For a dairy-free version, substitute the butter with a high-quality vegan butter or additional olive oil. Always check labels for hidden allergens to ensure the dish meets your dietary requirements.

Serviervorschläge

These savory steak fries are great alongside a grilled steak, juicy burgers, or even served as a standalone snack. The rich onion-garlic butter makes them flavorful enough to enjoy without any additional dipping sauces.

Recipe FAQ

How do I get fries crispy?

Soaking cut potatoes in cold water for 30 minutes removes excess starch, which helps achieve a crispier texture when baked. Dry them thoroughly before seasoning and baking.

Can I use other herbs instead of parsley?

Yes, fresh chives or thyme work well as alternatives to parsley, adding different but complementary flavors to the butter mixture.

Is it necessary to caramelize the onions slowly?

Slow caramelization develops the onions' natural sweetness and deep golden color, which enhances the rich flavor of the butter topping significantly.

How long should the fries bake?

Bake the fries for 35–40 minutes at 425°F (220°C), flipping halfway through to ensure even browning and crispness.

Can this side be made dairy-free?

Yes, substitute unsalted butter with vegan butter or extra olive oil to keep the dish dairy-free without losing flavor.
