What sets these fries apart is the technique. Instead of just seasoning the potatoes, we create a specialized butter infusion. By slowly cooking the onions until they reach a deep golden hue, we unlock a natural sweetness that perfectly complements the earthy russet potatoes and the punch of fresh garlic.

  • Potatoes: 4 large russet potatoes (scrubbed and cut into thick fries), 2 tablespoons olive oil, 1 teaspoon kosher salt, ½ teaspoon black pepper, ½ teaspoon smoked paprika (optional).
  • Onion-Garlic Butter: 4 tablespoons unsalted butter, 1 large yellow onion (thinly sliced), 3 cloves garlic (minced), 1 tablespoon fresh parsley (chopped, plus extra for garnish), ½ teaspoon sea salt, ¼ teaspoon black pepper.

Instructions

Step 1
Preheat oven to 425°F (220°C). Line a large baking sheet with parchment paper.
Step 2

While fries are baking, melt butter in a large skillet over medium heat. Add sliced onions, sprinkle with a pinch of salt, and cook, stirring often, until caramelized and deeply golden, about 15–18 minutes.
Step 5
Add garlic to the onions and cook for 1–2 minutes more, just until fragrant. Stir in chopped parsley and remove from heat.

Zusatztipps für die Zubereitung

To ensure maximum crispiness, make sure the potato wedges are spread out in a single layer with enough space between them; crowding the pan will cause them to steam instead of roast.

Varianten und Anpassungen

For a dairy-free version, substitute the butter with a high-quality vegan butter or olive oil. You can also experiment with different herbs like fresh thyme or rosemary instead of parsley for a different aromatic profile.

Serviervorschläge

These savory fries are the perfect accompaniment to a juicy grilled steak, a classic cheeseburger, or even as a standalone snack served with a side of garlic aioli or spicy ketchup.
