Since 1955, McDonald’s french fries have set the gold standard for fast food perfection. The secret behind their unmistakable taste isn’t just in the ingredients – it’s in the meticulous preparation process that transforms simple potatoes into crispy, golden strips of pure satisfaction. While the restaurant chain has modified their recipe over the decades, we’re sharing the authentic method to recreate these iconic fries in your home kitchen.
Selecting and preparing your potatoes
Start with fresh Russet potatoes, prized for their high starch content and low moisture. These characteristics are crucial for achieving that distinctive crispy exterior and fluffy interior. Peel the potatoes and cut them into precise 1/4-inch strips using a french fry cutter – uniformity is key for even cooking.
Once cut, rinse the potato strips thoroughly under cold water to remove excess starch. This step prevents the fries from sticking together and helps achieve that signature crispiness.
The secret behind the perfect brine
What sets McDonald’s fries apart is their unique brining process. Combine cold water with corn syrup, salt, and white vinegar. This solution not only enhances flavor but also creates the perfect texture. Soak the cut potatoes in this brine for 2 hours or overnight in the refrigerator.
After brining, drain and pat the potato strips completely dry. Any remaining moisture will prevent proper crisping during the frying process.
The double fry technique for perfect crispiness
The double-fry method is non-negotiable for achieving McDonald’s-level crispiness. Heat your oil to exactly 300°F for the first fry. Work in small batches – overcrowding the oil will drop the temperature too quickly. Fry for 5 minutes until the potatoes are pale and floppy.
Remove the fries and let them cool completely on paper towels. This cooling period allows the interior to set properly, ensuring that perfect contrast between crispy exterior and fluffy interior.
The final fry and seasoning process
For the second fry, heat your oil to 400°F. Add vegetable shortening to your oil – this is what creates that distinctive McDonald’s texture. Fry the cooled potatoes again until they turn golden brown, about 3-4 minutes.
The moment the fries come out of the oil, season them generously with fine salt. The hot oil helps the salt adhere perfectly to the surface. For authentic results, use a fine-mesh salt shaker to ensure even distribution.
Historical notes about the original recipe
Before 1990, McDonald’s cooked their fries in a mixture of beef tallow and shortening, which gave them their legendary taste. Today’s version uses vegetable oil, but home cooks can still recreate the classic flavor by adding a small amount of beef tallow to the frying oil.
The desert climate of the original McDonald’s location actually contributed to the fries’ superior texture. The dry air helped remove surface moisture from the cut potatoes, resulting in an exceptionally crispy final product.
Making McDonald’s-style french fries at home requires attention to detail and patience, but the results are worth the effort. Remember that temperature control is crucial – invest in a reliable deep-fry thermometer for best results. When stored properly in an airtight container, these fries can be frozen for up to three months, ready to be reheated in a 400°F oven whenever the craving strikes.

Ingredients
4 large Russet potatoes
¼ cup corn syrup
2 tablespoons white vinegar
2 tablespoons kosher salt
6 cups cold water
Vegetable oil for frying
½ cup vegetable shortening
Fine salt for seasoning
Directions
- Peel the potatoes and cut them into ¼-inch thick strips using a french fry cutter or sharp knife. Immediately place the cut potatoes in a large bowl of cold water to prevent browning. Rinse the potatoes under cold water until the water runs clear to remove excess starch.
- In a large bowl, combine cold water, corn syrup, white vinegar, and kosher salt. Stir until the salt dissolves completely. Add the cut potatoes to this brine solution, ensuring they are fully submerged. Cover the bowl with plastic wrap and refrigerate for 2 hours or overnight.
- Drain the potatoes and rinse thoroughly under cold water. Lay the potato strips on paper towels or clean kitchen towels and pat them completely dry. Any remaining moisture will prevent proper crisping.
- Heat oil in a large, heavy-bottomed pot or deep fryer to exactly 300°F. Working in small batches, fry the potatoes for 5 minutes until they’re pale and floppy. Remove with a slotted spoon and arrange on a wire rack set over a baking sheet. Allow the fries to cool completely at room temperature, about 30 minutes.
- Increase the oil temperature to 400°F. Add the vegetable shortening to the oil and allow it to melt completely. Working in batches again, fry the cooled potatoes for 3-4 minutes until they turn golden brown and crispy.
- Using a slotted spoon or spider strainer, remove the fries from the oil and transfer them to a paper towel-lined baking sheet. Immediately season generously with fine salt while the fries are still hot.
- Serve the fries immediately while they’re hot and crispy for the most authentic McDonald’s experience.
Notes
- Use only Russet potatoes for the best results – their high starch content is crucial for the right texture
- For extra authenticity, add 2 tablespoons of beef tallow to the oil during the second fry
- The fries can be frozen after the first fry – arrange them on a baking sheet and freeze until solid, then transfer to a freezer bag
- Maintain precise oil temperatures using a reliable deep-fry thermometer for best results
Frequently Asked Questions
Q: Why do I need to soak the potatoes in a brine solution?
A: The brine solution serves multiple purposes. The sugar from the corn syrup helps create the signature golden-brown exterior, while the salt and vinegar help remove excess starch. This process is crucial for achieving the distinct McDonald’s fry texture with a crispy exterior and fluffy interior.
Q: Can I make these fries ahead of time?
A: Yes, you can partially prepare these fries in advance. Complete the first fry, then freeze the fries in a single layer on a baking sheet. Once frozen, transfer them to a freezer bag where they’ll keep for up to 3 months. When ready to serve, fry them straight from frozen at 400°F until golden brown.
Q: Why is vegetable shortening necessary?
A: Vegetable shortening is essential for achieving the signature McDonald’s texture. It helps create a crispier exterior while maintaining a tender interior, and also contributes to the characteristic McDonald’s fry flavor. Don’t skip this ingredient if you want an authentic result.
Q: What kind of oil should I use for frying?
A: Use a neutral-flavored oil with a high smoke point, such as peanut oil, canola oil, or vegetable oil. The oil should be fresh and clean for the best results. McDonald’s uses a blend of oils, but for home cooking, any of these options will work well when combined with the vegetable shortening.
