What are McDonald’s french fries made of?

Fresh potatoes are washed, peeled, cut, and blanched to make McDonald’s fries,according to a video from the company.

What makes McDonald’s french fries taste so good?

It all started in the 1950s when the shortening company that gave McDonald’s vegetable oil couldn’t afford the equipment needed to hydrogenate the oil, which would extend its shelf life. So the supplier gave a blend of oil and beef fat instead, according to NPR.

Over time, McDonald’s and other fast-food joints made the beef fat part of their signature fry flavors. But in the 1980s, fast-food restaurants took the ingredient out when health advocates criticized how much “bad” saturated fat it added.

McDonald’s wanted to keep its signature beefy flavor but without the beef fat itself, so it came up with a solution. Now the fast-food chain adds “natural beef flavor” to its vegetable oil to give its fries their irresistibly meaty taste.

Are McDonald’s french fries vegan?

In the United States, McDonald’s french fries are not vegan, because the natural beef flavor is made with milk derivatives. However, if you’re across the pond in the United Kingdom, the fries (or “chips” as they’re called in the UK) are vegan since they’re not made with that beef flavor or coated in any animal substances.
