You’re sitting in a Chick-fil-A drive-thru, or maybe a local pub, staring at that glorious, lattice-shaped potato. It’s the superior fry. Don't even try to argue. It has more surface area for salt, a structural integrity that handles heavy dipping sauce like a champ, and a satisfying crunch-to-fluff ratio that a standard shoestring just can't touch. But have you ever actually stopped to wonder who invented waffle fries?
Most people just assume they’ve always existed. Like they were birthed fully formed from the earth alongside the potato itself. They weren't.

The history is actually a weird mix of 18th-century French culinary precision, 1970s industrial engineering, and a massive corporate trademark battle that most people have completely forgotten about. It isn’t just one guy in a hat saying "Eureka!" while staring at a tennis racket. It’s a evolution.
The French Connection: Pommes Gaufrettes
If we’re being technical—and in the world of fried potatoes, technicality is everything—the "waffle" shape wasn't invented by a fast-food chain. It started in France. They call them pommes gaufrettes.
The term "gaufrette" basically means small wafer or waffle. French chefs have been making these since at least the 1800s using a mandoline slicer. You take a potato, swipe it across a corrugated blade, turn the potato 90 degrees, and swipe again. Boom. You have a lattice.
But these weren't the thick, pillowy fries we know today. Classic French pommes gaufrettes are thin. They’re basically potato chips with holes in them. They were served as elegant garnishes in high-end Parisian bistros long before they were ever shoved into a cardboard carton and served with a side of ranch.
The leap from a delicate French garnish to a mass-produced American staple required a lot more than just a sharp knife. It required industrial refrigeration and a very specific company in Nebraska.
The 1979 Turning Point: Lamb Weston and the Crisscut
When people ask who invented waffle fries in the context of the modern food industry, the answer usually points toward the late 1970s. Specifically, a company called Lamb Weston.
Lamb Weston is a titan in the frozen potato world. You might not know the name, but you’ve definitely eaten their work. In 1979, they developed a specialized process for mass-producing what they called the "Crisscut" fry. This was a game-changer because, up until that point, making waffle fries at scale was a nightmare.
The potato is a fickle vegetable. If you try to cut a waffle shape into a standard russet potato using high-speed industrial machinery, the potato tends to shatter. Lamb Weston figured out the precise blade angles and par-frying techniques necessary to keep that lattice structure intact from the factory to the deep fryer.
They actually held a patent on the "Crisscut" design for years. This gave them a massive head start in the B2B market, selling the frozen, pre-cut fries to restaurants that wanted something more "premium" than the standard fry.
Chick-fil-A and the Waffle Fry Revolution
If Lamb Weston provided the hardware, Chick-fil-A provided the marketing.

Chick-fil-A didn't invent the waffle fry. They’ll be the first to tell you that. However, they are the reason the waffle fry became a household name in the United States. They introduced them to their menu in 1985.
Before 1985, Chick-fil-A actually served standard potato chips. They were fine, I guess. But they weren't great. They didn't travel well. They got soggy. The move to the waffle fry was a calculated risk to offer something that stayed hot longer and looked distinct.
The "waffle" shape is actually a thermal engineering masterpiece. Because of the holes (the "windows"), steam can escape easily. In a standard French fry, the steam often gets trapped inside the skin or the bag, turning the fry into a limp, sad noodle within five minutes. The waffle fry stays crispy longer because it breathes.
Chick-fil-A used Idaho #1 Russet potatoes, and they kept the skin on. That was a big deal. It made them feel "homemade" or "rustic" at a time when most fast food was moving toward hyper-processed, skinless, bleached potato sticks.
The Mystery of Edgar "Bill" Cecil
While Lamb Weston owns the industrial process, there is a persistent bit of food lore involving a man named Edgar "Bill" Cecil.
In some circles, Cecil is credited with inventing a specific type of waffle-cutting machine in the early 1980s. Some even claim he "invented" the waffle fry itself. The reality is more likely that he refined the mechanical process for smaller-scale operations.
There's often a disconnect between who "conceived" of a food and who "engineered" it for the masses. Think of it like the lightbulb. Edison didn't "invent" the idea of light from electricity, but he made the one that didn't burn out in five seconds and could be sold to everyone. Cecil and the engineers at Lamb Weston did the same for the waffle fry. They took a French chef's trick and turned it into a global commodity.

Why the Shape Actually Matters (It's Not Just Aesthetics)
Why do we care who invented waffle fries? Because the shape is the most efficient delivery system for condiments ever devised by man.
Think about the physics. A standard shoestring fry has a low "dip-to-potato" ratio. You can only get so much sauce on the tip. A waffle fry acts as a scoop. The lattice structure creates a series of "pockets" that trap sauce.
- Surface Area: A waffle fry has roughly 20-30% more surface area than a standard fry of the same weight.
- Texture Contrast: You get the crispy exterior on the ridges and the soft, mashed-potato interior in the thicker "nodes" where the ridges intersect.
- Structural Integrity: They don't break off in the dip.
It's basically the heavy-duty pickup truck of the potato world. It’s built for work.
Misconceptions and Legal Battles
There is a common myth that waffle fries were invented by a small diner in the Midwest that "accidentally" used a vegetable slicer wrong. That's a fun story. It's also completely false.
Industrial food history is rarely about accidents; it’s about patents. For a long time, if you wanted to sell a waffle-shaped fry, you had to deal with the "Crisscut" trademark. This is why you’ll see them called "Lattice Fries," "Grid Fries," or "Cross-cut Fries" on different menus. Everyone was trying to dance around the legal terminology while selling the same basic shape.
Interestingly, the popularity of the waffle fry has actually caused problems for potato farmers. To make a good waffle fry, you need a very large, consistently shaped potato. If the potato is too small, the "windows" in the lattice won't form correctly, and you just end up with a round potato chip with some ridges. This has led to a demand for larger Russet varieties specifically grown for the "waffle" market.
How to Get the Best Results at Home
If you're trying to recreate this history in your own kitchen, you need to understand that you can't just buy a cheap slicer and expect Chick-fil-A results.
Most home mandolines have a "waffle" setting. Use it. But here is the secret: you have to soak the potatoes in cold water for at least 30 minutes to remove the excess starch. If you don't, they will turn brown and bitter before they ever get crunchy.
Professional-grade waffle fries are almost always double-fried.
- The first fry is at a lower temperature ($325^\circ F$) to cook the inside.
- The second fry is at a higher temperature ($375^\circ F$) to get that golden-brown lattice.
The Future of the Lattice
We're starting to see "Waffle Fry 2.0" now. Sweet potato waffle fries are everywhere, though they are notoriously harder to keep crispy because of the higher sugar content. Some brands are even experimenting with "seasoned" lattices where the batter is injected into the potato before freezing.
It’s a long way from a 19th-century French kitchen.
So, while we can't pin the invention on one single person in a vacuum, we can thank the French for the idea, Lamb Weston for the machinery, and Chick-fil-A for making it a staple of the American diet.
Actionable Next Steps for the Fry Enthusiast
- Check the Label: Next time you're at a restaurant, look at the menu. If they call them "Crisscuts," they are likely sourcing from Lamb Weston or using the licensed name.
- The Soak Test: If you're making them at home, use the "double-fry" method mentioned above. It is the only way to avoid the dreaded "soggy middle."
- Storage Tip: Never put waffle fries in a sealed plastic container. The "windows" that help them stay crispy will actually work against them by pulling in trapped steam, making them mushy faster than a regular fry. Use a vented paper bag or an open bowl.
