Prep: 60 min | Cook: 28 min | Total: 1 hr 43 min
Cost: $5.65 total, $1.41 per serving
Ingredients
- 1 kg Russet Potatoes (peeled, cut into 3/4‑inch sticks after chilling)
- 1 tablespoon Salt (adds flavor to the boiling water and mash)
- 2 tablespoons Potato Starch (creates a crisp exterior when fried)
- 2 cups Avocado Oil (high smoke point; can substitute with beef tallow, canola or peanut oil)
- 1 teaspoon Fresh Thyme (optional, added after second fry for aroma)
- 2 Garlic Cloves (minced, optional, added with thyme after frying)
Instructions
Peel the potatoes
Using a vegetable peeler, remove the skin from the russet potatoes. Rinse briefly to remove any residue.
Time: PT5M
Boil the potatoes whole
Place the peeled potatoes in a large pot, cover with just enough cold water to submerge them, add 1 tablespoon salt, and bring to a boil. Once boiling, reduce to a gentle simmer and cook until a knife slides easily into the center (about 20 minutes).
Time: PT20M
Drain and mash
Drain the potatoes and let them sit for 2 minutes to steam off excess moisture. Transfer to a large mixing bowl and mash until smooth, avoiding a puree.
Time: PT5M
Incorporate starch and season
Add 2 tablespoons potato starch and a pinch of salt to the mashed potatoes. Fold gently until fully incorporated; the mixture should be slightly sticky but not wet.
Time: PT5M
Form a sheet and chill
Place a sheet of parchment paper on a flat surface. Transfer the potato‑starch mixture onto the parchment and roll it out to about 1‑inch thickness using a rolling pin. Cover with another piece of parchment and place the bagged sheet in the refrigerator for 30 minutes to let the starch gel.
Time: PT35M
Slice into fry shapes
Remove the chilled sheet from the fridge. Using a sharp knife, cut the sheet into 3/4‑inch wide strips, then cut each strip into 3‑inch long sticks.
Time: PT5M
First fry (blanch)
Heat avocado oil (or beef tallow) in a deep fryer or heavy pot to 375°F (190°C). Fry the raw fries in small batches for about 3 minutes, just until they begin to turn opaque but not browned. Remove with a slotted spoon and let drain on paper towels.
Time: PT3M
Temperature: 375°F
Rest briefly
Allow the blanched fries to rest for 2 minutes on a wire rack. This lets steam escape and the surface dry.
Time: PT2M
Second fry (crisp)
Return the fries to the hot oil and fry for another 3‑4 minutes, or until golden‑brown and super‑crisp. Remove, drain, and immediately toss with minced garlic and thyme if using.
Time: PT3M
Temperature: 375°F
Serve
Transfer the fries to a serving bowl, sprinkle with a pinch of flaky sea salt, and serve hot.
Time: PT2M

Ingredient Substitutions
- Instead of Russet Potatoes: Yukon Gold potatoes, sweet potatoes (will change flavor)

Equipment Needed
- Large Pot
- Vegetable Peeler
- Chef's Knife
- Cutting Board
- Large Mixing Bowl
- Ziploc Bags (or reusable freezer bags)
- Rolling Pin or Pastry Bar
- Parchment Paper
- Refrigerator

- Paper Towels
Critical Steps — Do Not Skip
- Boiling the potatoes just until fork‑tender (not overcooked).
- Incorporating potato starch without over‑mixing.
- Chilling the mashed sheet for at least 30 minutes to set the starch.
- Double‑frying at 375°F: first to cook, second to crisp.
Chef Tips from the Video
- Beef tallow adds a classic frites flavor; substitute with avocado oil for a neutral taste.
- A light dusting of cornstarch instead of potato starch works in a pinch.
- Use a kitchen timer for each fry batch to keep the cooking time consistent.
Troubleshooting
Fries are soggy after the second fry.
Make sure the oil stays at 375°F and do not overcrowd the pot; increase the second fry time by 30 seconds.
Inside of fries is gummy or dense.
Do not over‑mix the starch into the mash and ensure the potatoes are only simmered until fork‑tender, not falling apart.
Fries break when cutting after chilling.
Slice while the sheet is still firm; if it softens, return to the fridge for a few more minutes.
Storage
Refrigerator: Store leftover fries in an airtight container for up to 2 days. Reheat in a hot oven (425°F) for 5‑7 minutes to regain crispness.
Freezer: Not recommended; texture degrades after freezing.
Room temperature: Do not leave at room temperature for more than 2 hours due to food safety.
Make-Ahead Tips
- The mashed potato‑starch sheet can be prepared up to 24 hours ahead and kept chilled.
- You can pre‑slice the chilled sheet and freeze the raw sticks on a tray; fry from frozen for a slightly longer second fry.
Frequently Asked Questions
What is the cultural significance and history of French fries in Belgian and French cuisine?
French fries, or "frites," originated in the Meuse Valley of Belgium where street vendors traditionally fried thin potato sticks. They became popular in France and later worldwide, symbolizing comfort food and often served with sauces like mayo or aioli.
How do ultimate French fries differ from classic restaurant‑style fries?
Ultimate fries use a mashed‑potato‑starch sheet that is chilled, sliced, and double‑fried, creating a fluffy interior and a glassy‑crisp exterior, whereas classic fries are simply cut raw potatoes and fried once.
What traditional regional variations of fries exist in French and Belgian cuisine?
In Belgium, fries are often served with a variety of sauces and paired with mussels (moules‑frites). In France, "pommes frites" are thinner and commonly accompany steak "frites". Some regions add herbs like thyme or rosemary for extra aroma.
What occasions or celebrations are French fries traditionally associated with in Belgian culture?
Fries are a staple at casual gatherings, street festivals, and as a side to the national dish of mussels. They’re also a popular late‑night snack after bars and cafés.
Why does this ultimate French fry recipe use a double‑fry method instead of a single fry?
The first fry cooks the interior without forming a crust, while the second fry at high heat creates the ultra‑crisp exterior. This two‑step process prevents sogginess and yields the signature glassy crunch.
What are the most common mistakes to avoid when making ultimate French fries at home?
Common errors include over‑boiling the potatoes, over‑mixing the starch, skipping the chilling step, and frying at too low a temperature. Each mistake leads to gummy interiors or soggy exteriors.
Can I make the ultimate French fries ahead of time and how should I store them?
Yes. Prepare the mashed‑potato‑starch sheet, chill, and slice up to 24 hours in advance. Keep the raw sticks in a sealed bag in the refrigerator; fry them when ready. Leftover fried fries can be refrigerated and reheated in a hot oven.
What texture and color should I look for to know the fries are done?
After the second fry, the fries should be deep golden‑brown with a glossy surface and emit a crisp sound when tapped. Inside they should feel fluffy and yield easily to a fork.
What does the YouTube channel ChefSteps specialize in?
ChefSteps focuses on modernist cooking techniques, scientific explanations, and precise, equipment‑driven recipes that help home cooks achieve restaurant‑quality results.
How does the YouTube channel ChefSteps' approach to French fry recipes differ from other cooking channels?
ChefSteps emphasizes the science behind texture—using starch gels, temperature control, and chilling—while many other channels rely on traditional cutting and single‑fry methods. Their videos often include detailed timing and equipment tips.
