You know the smell. That heavy, salty, peanut-oil-soaked aroma that hits you the second you walk through the door of a Five Guys. It’s intoxicating. Then they hand you that brown paper bag, already translucent with grease, and it’s filled to the brim with fries that actually taste like potatoes. Most fast-food fries taste like extruded salty cardboard. These don’t.
So, you try it at home. You chop up some Russets, toss them in a fryer, and… they’re okay. But they aren't those fries. They’re either too crunchy, or they turn into limp noodles within three minutes.
Making a 5 guys french fries recipe that actually works requires more than just a deep fryer. It requires understanding the obsession with starch, the science of double-frying, and the specific brand of oil they use. Honestly, it’s a bit of a process. If you’re looking for a quick ten-minute snack, go buy a bag of frozen crinkle-cuts. But if you want that specific, creamy-on-the-inside, golden-on-the-outside perfection, you have to follow the rules they’ve been using since 1986.
The Potato is the Main Character (and it’s picky)
Five Guys doesn’t just buy any old bag of potatoes from the local wholesaler. They are incredibly public about using "Northern-grown" potatoes, specifically those grown above the 42nd parallel. Think Idaho or Washington state. Why? Because the colder climate leads to a slower growing season, which results in a denser potato with a very specific starch-to-water ratio.
If you use a "new" potato or a waxy red potato for a 5 guys french fries recipe, you’ve already lost. Waxy potatoes have too much sugar and moisture. They’ll turn dark brown and bitter before the inside is even cooked. You need the Russet Burbank. It’s the king of frying.
At the restaurants, you'll see the sacks of potatoes stacked up in the dining area. They aren't just for decoration. They are transparent about where they come from that day—literally writing the farm's name on a chalkboard. That’s not just marketing; it’s a warning that the quality of your fry depends entirely on the dirt it grew in.

The Secret "Water Bath" Nobody Does Long Enough
Most home cooks rinse their potatoes once. That is a mistake.
When you cut a potato, you release a massive amount of surface starch. If that starch stays on the fry when it hits the oil, it burns instantly. It creates a gritty, dark coating that keeps the heat from penetrating the center. Five Guys technicians—yes, they take it that seriously—wash the fries until the water runs completely clear.
- Cut your fries into thick sticks (about 3/8 of an inch).
- Throw them in a massive bowl of cold water.
- Agitate them. The water will turn cloudy, almost like milk.
- Dump it. Repeat.
- Repeat again.
You’re looking for water so clear you could drink it. But here is the part where most people fail: the soak. You shouldn't just rinse them; you should soak them for at least two hours. Some enthusiasts even suggest an overnight soak in the fridge. This leaching process is what gives the fries that "creamy" mashed-potato texture on the inside once they’re fried.
The Peanut Oil Factor
If you use vegetable oil, canola oil, or (heaven forbid) olive oil, it won't taste right. Five Guys uses 100% refined peanut oil. There is no cholesterol, no trans fats, and it has a high smoke point, but more importantly, it has a distinct flavor profile that is slightly nutty and very clean.
Peanut oil is expensive. I get it. But it’s non-negotiable for an authentic 5 guys french fries recipe. Refined peanut oil is generally safe for those with peanut allergies because the proteins that trigger the allergy are removed during the refining process, but always check the label of the specific brand you buy.

The Precision of the Two-Stage Fry
This is where the magic happens. You cannot cook a raw potato stick to perfection in one go. If you try, the outside will be a burnt husk by the time the inside is soft. Or, the inside will be raw while the outside looks "done."
The Pre-Cook (The Blanch)
The first fry happens at a lower temperature, usually around 325°F (163°C). You aren't trying to make them crispy yet. You are essentially boiling the potato in oil. You want them to be limp and pale.
How do you know they're done? Use the "pinch test." Pick a fry out (carefully!) and squeeze it. It should offer no resistance. It should feel like a soft, cooked vegetable. At Five Guys, they call this the "dull" stage. They take them out, put them in a cooling rack, and let them rest.
The Rest (Crucial Step)
You cannot go straight from the first fry to the second. The fries need to sit for at least 15 minutes, though 30 is better. This allows the internal moisture to redistribute. If you skip this, the steam inside will blow the crispy crust right off during the second fry, leaving you with a greasy mess.
The Final Blow (The Hard Fry)
Now, crank that heat up to 375°F (190°C). This is the "flash fry." It only takes about two to three minutes. You’re looking for that signature Five Guys "flecking"—little bubbles and dark spots on the skin that indicate the starch has properly caramelized.

The Salt and the Shake
Once they come out of that second fry, they need to be tossed. Five Guys is famous for the "shaking" of the fries. It’s not just for show. It knocks off excess oil so they don't get soggy.
For the salt, don't use fine table salt. Use a coarse kosher salt or a specific fry salt. If you want the "Cajun Style," you’re looking for a heavy dose of McCormick Bayou Cajun Seasoning, or a blend of garlic powder, onion powder, paprika, oregano, white pepper, and a whole lot of cayenne.
Why Your Home Version Still Might Taste Different
Even if you follow this 5 guys french fries recipe to the letter, there’s a variable you can’t easily replicate: the volume of oil.
A commercial fryer holds gallons of oil. When you drop a basket of fries into a commercial vat, the temperature barely dips. When you drop a batch of fries into a small pot on your stove, the temperature plummets. This causes the potato to absorb oil rather than sear, which leads to grease-heavy fries. To fix this at home, fry in very small batches. If you think you're doing too few, you're probably doing the right amount.
Also, Five Guys doesn't peel their potatoes. Never. That skin adds a rustic, earthy flavor and provides structural integrity to the fry. If you peel them, you’re just making standard diner fries.
Actionable Steps for Your Next Batch
If you're ready to try this tonight, don't wing it. Precision is the only way to get that specific result.
- Buy the right spud: Get a bag of Idaho Russets. Look for the ones that are heavy for their size and have a rough, "netted" skin.
- The 3-stage wash: Wash, soak for 2 hours, and then dry them completely. If they are wet when they hit the oil, it’s dangerous and it ruins the texture. Use paper towels and get them bone-dry.
- Thermometer is king: Don't guess the oil temperature. A $15 clip-on candy thermometer will save your life (and your dinner).
- The 325/375 Rule: Stick to those temperatures. 325°F for the 5-minute blanch, 375°F for the 2-minute finish.
- The Cooling Rack: Don't drain fries on a flat paper towel on a plate. They will steam on the bottom and get soggy. Use a wire cooling rack so air can circulate all the way around them.
The real secret to the 5 guys french fries recipe isn't a "secret sauce" or a hidden ingredient. It's just an obsessive commitment to the physics of a potato. It's the refusal to take shortcuts like freezing or pre-boiling in water. It’s just oil, salt, and a very specific type of heat management. Once you nail the double-fry technique, you’ll realize why they can charge what they do for a "large" fry that’s basically a literal bucket of potatoes.
