As more fast-food restaurants introduce plant-based menu items, many vegans are asking the same question: Are Burger King fries vegan?
The short answer is yes—Burger King fries do not contain any animal ingredients. However, there is a risk of cross-contamination, depending on the location.
In this guide, we’ll take a closer look at how Burger King prepares its fries, the cross-contamination risks, and other vegan-friendly options on the menu.
Burger King Fries and Cross-Contamination
Burger King’s official allergen information states that its fries are cooked in a shared fryer. However, things get confusing when you look at the details.
What Does Burger King Say?
On Burger King’s allergen page, they list which menu items are cooked in shared fryers. The list includes:
- Fish Filet
- Pork Sausage
- Chicken Nuggets
- Hash Browns
- French Toast Sticks
- Onion Rings
Notably, French fries are not mentioned in this list. This suggests that fries may have their own dedicated fryer, but it varies by location.
How to Know If Your Burger King Fries Are Vegan
Since fryer use differs from restaurant to restaurant, the best way to confirm is to ask at your local Burger King. If the fries are cooked separately, then they are completely vegan-friendly.
However, if cross-contamination is a concern for you, you may want to avoid the fries at locations that use shared fryers.
Other Vegan Options at Burger King
Burger King has expanded its plant-based menu, making it easier for vegans to find a meal beyond fries.
- Impossible Whopper – Made with Impossible Meat. Order without mayo or cheese to keep it vegan. Be aware that it is grilled on the same surface as meat, though you can request it to be microwaved.
- Other Impossible Burgers – The Impossible King and Impossible Southwest Bacon Whopper can also be made vegan by removing dairy-based ingredients.
- Side Salad – A simple option; order without cheese or croutons. Ken’s Golden Italian dressing is vegan-friendly.
- Breakfast Items – French Toast Sticks and Hash Browns are technically vegan but may be fried in shared oil.
- Drinks – Most soft drinks, iced tea, lemonade, apple juice, and bottled water are vegan.
- Onion Rings? – Previously contained dairy, but Burger King recently removed it from the allergen list. Since there’s no official confirmation, check with your location before ordering.
Final Thoughts
Burger King fries do not contain animal products, but their vegan status depends on the fryer used at each location. Since cross-contamination is possible, it’s best to ask at your local restaurant if they use a separate fryer.
For a full vegan meal at Burger King, the Impossible Whopper (without mayo or cheese), side salad (without croutons and cheese), and French Toast Sticks are your best bets.
As more fast-food chains expand their plant-based options, Burger King remains a decent choice for vegans—just be sure to double-check ingredients and preparation methods before ordering.
