Luckily, McDonald’s does not use peanut oil to fry their food. 

Earlier, when McDonald’s had just started their business, they used to fry their food in beef fat. This was regardless of whether the food items were supposed to be vegetarian and vegan, like their French fries and hash browns

However, after the company got a few consistent complaints from customers who did not prefer beef products, they changed their oil preference in the 1990s.

Ever since there have been changes in the type of oil in the McDonald’s kitchen, however, artificial beef flavoring has been a common aspect throughout the years. 

The fact that such a large multinational company does not use peanut oil to fry any of its products may be a relief to so many people. It is especially true for people with peanut allergies, as they can also be fatal in some extreme cases. 

What Oil Does McDonald’s Use For Frying? 

As per the official website of McDonald’s, they have completely switched to canola-blend oil for frying all their food. 

After they took beef fat out of their kitchen for deep frying purposes, McDonald’s tried switching to different oil blends

In 2002, the company switched to a soy-corn oil blend, which was later changed to trans-fat-free oil in 2007. Now the company traded to canola-blend crude, and the artificial beef flavor is added to retain the original taste of all their menu items.

So, the company began experimenting with the sort of oil they would use, of which peanut oil had a brief stint. However, it was taken off very soon, again due to concerns about allergies.
