are in n out fries gluten free

In-N-Out is a popular burger chain known for its delicious hamburgers and scrumptious fries. If you are following a gluten-free diet or have celiac disease, it’s important to be aware of what you can and cannot consume. In this article, we will explore whether In-N-Out fries are gluten-free or not.

Ingredients of In-N-Out Fries

The first step in determining the gluten-free status of In-N-Out fries is to examine their ingredients. Here are the ingredients used to make In-N-Out fries:

  • Potatoes
  • Vegetable oil (high oleic canola oil)
  • Salt

Based on the ingredient list, In-N-Out fries are made from simple and gluten-free ingredients. However, there are factors beyond individual ingredients that determine whether a food item is truly gluten-free.

Cross-Contamination Risks

Cross-contamination can occur when gluten-free foods come into contact with gluten-containing ingredients or surfaces. In the case of In-N-Out fries, there is a risk of cross-contamination during the cooking process. Here are some potential sources of cross-contamination:

  1. Oil: Although In-N-Out uses a separate fryer for their fries, there is a possibility of shared oil with gluten-containing items, such as breaded chicken.
  2. Utensils and Fry Baskets: If the same utensils and fry baskets are used for both fries and gluten-containing items, cross-contamination can occur.
  3. Food Preparation Surfaces: If the surfaces where fries are prepared come into contact with gluten-containing ingredients, it can lead to cross-contamination.

It is important to note that while In-N-Out takes precautions to minimize cross-contamination, there is still a risk involved. Individuals with severe gluten sensitivity or celiac disease may want to exercise caution or choose alternatives.
