Are Carl’s Juniors French fries gluten-free?

Whether you have celiac disease, gluten sensitivity, or are simply trying to avoid gluten, eating at restaurants with gluten-free options can be challenging. With so many ingredients and preparation methods to consider, it’s hard to know exactly what’s safe.

What is Carl’s Jr.?

Are French fries generally gluten-free?

Most French fries are made by simply frying potato slices in oil. Potatoes themselves don’t contain gluten, so plain French fries are usually fine on a gluten-free diet. However, there are some important things to consider:

  • Cross-contamination – Fries may come into contact with gluten-containing foods during preparation or frying.
  • Breading/seasoning – Some fries have a light breading or are seasoned with ingredients that contain gluten.
  • Fryer oil – If the fryer oil is also used to cook breaded, gluten-containing foods, it can contaminate the fries.

So while French fries are often gluten-free, it depends entirely on how they are prepared and cooked. Restaurants need to take steps to prevent cross-contamination and ensure all ingredients and seasonings used on the fries are gluten-free.

What has Carl’s Jr. said about their French fries?

According to Carl’s Jr.’s website, their natural-cut French fries are “free of gluten-containing ingredients.” They use a separate fryer for their fries that only fries potatoes, so there should be minimal risk of cross-contamination. They caution that because their kitchens handle many other menu items that contain gluten, there is still a chance of cross-contact.

  • Train team members on food allergy procedures and prevent cross-contact between foods

Following proper protocols forfried food preparation and using dedicated fryers significantly reduces the risk of gluten cross-contamination.

Do Carl’s Jr. fries contain any other ingredients besides potatoes?

According to Carl’s Jr.’s website, their natural-cut fries only contain three ingredients:

  • Potatoes
  • Vegetable oil (canola, soybean, cottonseed, sunflower)
  • Dextrose (natural sugar derived from corn, potatoes, rice)

They do not list any additional seasoning or ingredients. The dextrose they use as an anti-caking agent should also be gluten-free, though it’s always advisable to check with the restaurant to confirm their suppliers.

What about other potential sources of gluten?

Besides the ingredients, there are a few other ways gluten could get into Carl’s Jr. fries:

  • Fryer oil – While they use dedicated fryers, if the oil was previously used for gluten-containing foods like onion rings or chicken strips, it could contaminate the fries.
  • Shared equipment – If scoops or baskets are used for multiple menu items, traces of gluten could transfer.
  • Worker hands – Employees touching gluten-containing buns then grabbing fries without washing hands in between could cause cross-contact.

Proper training on changing gloves between foods and not re-using tools for different items reduces this kind of risk.
