Crispy Golden Leek and Potato Matchstick Frites Tips, FAQ & printable recipe

Tips for success

To maximize the lifespan of your oil, filter it through a fine-mesh sieve or cheesecloth after it has cooled completely. This removes any small bits of vegetable that could burn during future frying sessions, keeping your oil clean and ready for the next time you want to make these crispy matchsticks. Store the cooled, filtered oil in a tightly sealed container in a cool, dark place to prevent oxidation and maintain its neutral flavor profile for several weeks.

If you find that your matchsticks lose their crispness after sitting for a while, you can briefly refresh them in a preheated 350°F (175°C) oven for two to three minutes. Spread them in a single layer on a baking sheet and watch them carefully, as their thin structure makes them prone to burning quickly.

This brief re-heating process will drive off any moisture they may have absorbed from the air and restore that essential shatter that makes them such a delightful addition to any meal.

Variations

• Herbed Matchsticks: Toss the finished matchsticks with a mixture of finely minced fresh parsley and chives instead of smoked paprika for a brighter, fresher flavor profile that pairs beautifully with lighter dishes.
• Spicy Garlic Straws: Add a half teaspoon of garlic powder and a pinch of cayenne pepper to the salt and paprika mix for a bolder, slightly spicy kick that adds depth to the overall flavor.

Storage and make-ahead

Fridge

Do not store fried matchsticks in the refrigerator, as moisture will destroy the texture.

Reheat

Spread on a baking sheet and heat in a 350°F (175°C) oven for 2-3 minutes until crisp.

Store any leftovers in an airtight container at room temperature for up to one day, though they are best consumed immediately after frying. If they lose their crispness, follow the refreshing tip provided.

Avoid storing them in the refrigerator, as the moisture will cause them to soften and lose their texture entirely. Keep them in a dry, cool environment away from direct sunlight or heat sources to maintain their quality for as long as possible before they eventually lose their structural integrity.

You can prepare the potato and leek matchsticks ahead of time by julienning them and storing the potatoes in a bowl of cold water in the refrigerator for up to three hours. Change the water halfway through to keep them fresh. The leeks can be kept in a sealed container in the refrigerator. However, for the best results, always spin them dry immediately before frying. Do not fry them in advance, as they will inevitably lose their crispness and become soft upon cooling.

Serving ideas

These matchstick frites serve as a versatile garnish that adds both height and texture to a variety of dishes. Place a generous nest of the crispy straws atop a seared steak, a bowl of creamy potato leek soup, or a fresh green salad to provide a contrast to the soft textures of the main dish.

The combination of the salty potato and the slightly sweet, smoky leeks works exceptionally well with rich, savory items, helping to cut through the depth of flavors and add a necessary lightness.

For a more casual presentation, serve the matchsticks in a small, parchment-lined cone or a shallow bowl alongside your favorite dipping sauce. They can also be used to add a professional, bistro-style finish to roasted poultry or pan-seared fish.

Regardless of how you choose to serve them, ensure they are added to the dish at the very last moment before serving to maintain their maximum crispness. Their visual appeal and delicate crunch will immediately elevate the overall dining experience for your guests.

Crispy Golden Leek and Potato Matchstick Frites

Prep 20 minCook 2 minTotal 22 minServes 4

Ingredients

• 400 g Russet potatoes, peeled and julienned into 2mm matchsticks
• 200 g white leek barrels, julienned into 2mm matchsticks
• 1 tbsp cornstarch
• 4 cups peanut oil for frying
• fine sea salt to taste
• smoked paprika to taste

Instructions

1. Using a sharp chef's knife or mandoline, carefully julienne the peeled Russet potatoes and cleaned white leek barrels into consistent two-millimeter matchsticks. Place the potato matchsticks into a bowl of cold water to remove excess starch, then rinse thoroughly. Transfer the potatoes to a salad spinner and spin until they are bone-dry, as any surface moisture will cause the oil to splatter dangerously during the frying process.
2. Lightly dust the prepared leek matchsticks with cornstarch, shaking off any excess. Heat the peanut oil in a large heavy-bottomed pot until it reaches a steady 360°F (182°C). Working in small batches to maintain oil temperature, carefully lower the potato matchsticks into the hot oil. Fry for approximately ninety seconds until they are golden and weightless. Repeat the process separately for the leek straws, ensuring they do not burn.
3. Immediately transfer the fried potato and leek matchsticks onto a tray lined with paper towels to drain any excess oil. While still hot, gently toss the crispy straws with fine sea salt and a dusting of smoked paprika. Serve the matchsticks immediately while they are at their peak of crispness to ensure the best texture and flavor for the diners.
