Which brand of French fries are gluten-free? Your Safe Eating Guide

5 min read

While potatoes are naturally gluten-free, a 2024 study in burger restaurants found that 4.9% of fry samples had detectable gluten contamination from shared cooking environments. This makes knowing which brand of French fries are gluten-free and understanding preparation methods crucial for individuals with celiac disease or gluten sensitivity.

Quick Summary

Potatoes are naturally gluten-free, but many brands and restaurants have gluten in coatings or risk cross-contact from shared fryers. Frozen brands like Ore-Ida offer labeled gluten-free options. At restaurants, confirming a dedicated fryer is the safest approach, as places like Five Guys and Chick-fil-A have dedicated fryers.

Key Points

  • Check for Coatings: The potato is naturally gluten-free, but many frozen and restaurant fries add wheat-based coatings or batter for crispiness.

  • Dedicated Fryer is Key: At restaurants, the greatest risk of gluten contamination comes from shared deep fryers used to cook other breaded items.

  • Reliable Brands: Look for frozen brands that explicitly label their fries as gluten-free, with Ore-Ida being a widely cited example.

  • Fast-Food Best Bets: Fast-food restaurants like Five Guys and Chick-fil-A are often safe choices because they use dedicated fryers for their fries.

  • Always Ask Questions: Never assume. When dining out, always ask a manager about the cooking process and whether a dedicated fryer is used for fries.

  • Not All Locations are Equal: Frying practices can vary by restaurant location, even within the same chain, so confirming locally is essential.

  • No Guarantee with Shared Fryers: Heat does not kill or eliminate gluten proteins, so cooking in shared oil will inevitably transfer gluten.

Navigating the Gluten-Free French Fry Landscape

For many following a gluten-free diet, the simple pleasure of French fries can be a source of anxiety. The core ingredient, the potato, is inherently gluten-free. However, gluten can be introduced during the manufacturing process via coatings and flavorings or, most commonly, in restaurants through cross-contamination in shared deep fryers. The good news is that many brands and fast-food chains offer safe, delicious, gluten-free options if you know what to look for.

Frozen Gluten-Free French Fries for Home

Choosing frozen fries is often the safest bet for a gluten-free diet because you can control the cooking environment and rely on explicit labeling. When shopping, always read the packaging for allergen statements and look for brands that are certified gluten-free.

  • Ore-Ida: This is one of the most reliable brands for gluten-free fries. Many of their potato products, including crinkle-cut fries and hash browns, are explicitly labeled gluten-free on the packaging. They are produced and labeled in compliance with FDA regulations, meaning they contain less than 20 ppm of gluten.
  • Alexia: While some Alexia products may not contain gluten ingredients, they often have allergen statements indicating they are made in shared facilities, which poses a risk for those with celiac disease. Plain fries are a safer bet than seasoned or coated varieties. It is crucial to always double-check the label.
  • Grown in Idaho: This brand states that its items are developed without added gluten ingredients but does not formally validate the finished products as gluten-free. For those with severe gluten sensitivities, this lack of formal certification may be a concern. Always check the label for the most recent information.
  • McCain: Some McCain products, particularly seasoned or crispy varieties, contain wheat. They also use shared facilities, so a careful review of ingredient and allergen statements is necessary before consumption.

Gluten-Free French Fries at Fast-Food Restaurants

Dining out with celiac disease or a gluten sensitivity requires vigilance, especially when it comes to fried food. The risk of cross-contamination from a shared fryer is significant and can transfer enough gluten to cause a reaction. However, several chains have specific practices that make their fries safe.

  • Five Guys: A popular choice, Five Guys fries are cooked in a dedicated fryer using peanut oil. Since their menu items contain no other fried products with gluten, their fries are generally considered safe from cross-contamination. They offer both Five Guys Style and Cajun Style, which are both gluten-free by ingredients.
  • Chick-fil-A: Their famous Waffle Potato Fries are cooked in a dedicated fryer with canola oil. While the fries themselves are gluten-free, their website does note that they are prepared in the same area as glutenous foods, which could be a concern for highly sensitive individuals.
  • In-N-Out Burger: In-N-Out's hand-cut fries are made with simple ingredients and are cooked in a dedicated fryer. This minimizes the risk of cross-contact, although the chain does not officially list them as certified gluten-free on its website.
  • Shake Shack: Shake Shack's crinkle-cut fries and cheesy fries do not contain gluten or wheat ingredients and are cooked in a dedicated basket, making them a safe option.
  • Red Robin: Red Robin offers steak fries cooked in a dedicated gluten-free fryer by request at some locations. It's essential to confirm this practice with the staff at your specific restaurant when ordering.
  • McDonald's (US): In the U.S., McDonald's fries contain a “natural beef flavor” that includes hydrolyzed wheat, making them unsafe for a strict gluten-free diet. Some international locations, like those in the UK, have different practices, but checking locally is always advised.

The Critical Factor of a Dedicated Fryer

Cross-contact, or the exposure of gluten-free food to gluten-containing ingredients, is a major concern in restaurants that use a shared fryer. High heat does not eliminate gluten, meaning particles from breaded items like chicken nuggets, onion rings, or battered fish can remain in the oil and contaminate the fries. For a strict gluten-free diet, always ask about the use of a dedicated fryer. If a dedicated fryer is not available, or if the establishment cannot guarantee one, the risk is too high for those with celiac disease.

How to Ensure Your Fries are Truly Gluten-Free

For anyone with a gluten-related disorder, here are essential tips to ensure your French fries are safe:

  • Read Frozen Product Labels: Always read the ingredient list and allergen statement on the packaging of frozen fries. The presence of a gluten-free certification logo or an explicit statement is the best indication of safety.
  • Ask at Restaurants: Don't rely on assumptions. Ask a manager whether a dedicated fryer is used for French fries and confirm if the oil is separate from other breaded items. Be specific in your questioning.
  • Avoid Coated Varieties: Unless certified gluten-free, assume seasoned, battered, or curly fries are not safe. Many of these products use wheat flour for a crispy texture or to bind seasonings.
  • When in Doubt, Leave it Out: If you cannot get a definitive answer about frying practices or ingredients at a restaurant, it is always safest to opt for another meal choice to avoid potential gluten exposure.

Conclusion

While French fries may seem like a simple snack, ensuring they are truly gluten-free requires careful attention to detail. The brand and cooking method are the two most critical factors. For frozen fries, reliable brands like Ore-Ida offer explicitly labeled gluten-free options, while at fast-food restaurants, chains like Five Guys and Chick-fil-A are often safe due to their use of dedicated fryers. Always ask questions and read labels to protect your health and enjoy your fries without worry. For more information on celiac disease and gluten-free living, visit Beyond Celiac.
