Why Many Boxed Scalloped Potato Mixes Contain Gluten
For many, boxed scalloped potatoes are a go-to for a quick and easy side dish. The pre-sliced, dehydrated potatoes and seasoning packet make preparation a breeze. However, this convenience often comes at the expense of a gluten-free diet. The primary reason most conventional mixes contain gluten is the sauce or seasoning packet. To achieve a thick, creamy consistency, manufacturers frequently use wheat flour as a thickener. This ingredient is a major source of gluten and is not safe for those with celiac disease or a gluten sensitivity. Additionally, other ingredients derived from gluten-containing grains, such as malt flavoring, can also be present.
Identifying Gluten on a Food Label
Navigating food labels can be complex, but for those avoiding gluten, it's a vital skill. In the U.S., the Food and Drug Administration (FDA) requires that packaged foods labeled "gluten-free" contain less than 20 parts per million (ppm) of gluten. However, simply looking for this label is not enough, especially since many brands may not seek certification. A thorough inspection of the ingredients list is necessary to spot common gluten sources, including:
- Wheat: Often listed as wheat flour, wheat starch, or variations like spelt, durum, and semolina.
- Rye: Another grain containing gluten.
- Barley: Look out for malt extract, malt flavoring, or brewer's yeast, all derived from barley.
- Modified Food Starch: This ingredient can sometimes be derived from a gluten-containing source. If the source is not specified, further research or manufacturer contact may be needed.
- Natural and Artificial Flavorings: Certain flavorings, especially savory ones, can hide gluten from barley.
If a product is manufactured on shared equipment with wheat products, a "may contain wheat" advisory is sometimes included, though this is voluntary. For individuals with celiac disease, this risk of cross-contamination is a serious concern, and products with such warnings should be avoided.
Finding Safe, Gluten-Free Alternatives
Fortunately, there are several ways to enjoy scalloped potatoes while maintaining a strict gluten-free diet. Some brands, like Idahoan, offer specific products labeled as "naturally gluten-free". These use naturally gluten-free ingredients, like rice flour or cornstarch, to thicken the sauce instead of wheat.

Making Your Own Delicious Gluten-Free Scalloped Potatoes
Creating your own scalloped potatoes from scratch is a rewarding and guaranteed gluten-free option. The process allows for full control over ingredients, preventing any cross-contamination issues and enabling flavor customization. A simple, naturally gluten-free sauce can be made by creating a roux with butter and a gluten-free flour blend (like Cup4Cup or a mix of cornstarch and rice flour), then slowly whisking in milk. For an even easier, naturally thickened sauce, you can rely on the starches from the potatoes themselves in a simple cream-based sauce. Season with salt, pepper, and your choice of herbs and spices. Top with a delicious gluten-free cheese and bake until tender and bubbly. This method ensures a safe, delicious, and deeply satisfying dish for all to enjoy.
Conclusion: Always Read, Never Assume
In conclusion, the question of "do boxed scalloped potatoes have gluten?" doesn't have a single, simple answer. The safety of a particular product is entirely dependent on its manufacturer and ingredients. While the core ingredient, the potato, is naturally gluten-free, the sauce mix in most conventional boxed versions contains wheat flour as a thickener, making it unsafe for those with gluten sensitivities. For a reliable, safe side dish, always check the product label for clear gluten-free certification. For ultimate control and customization, preparing a gluten-free version from scratch is the best option, ensuring a delicious and safe meal every time. Rely on ingredient lists, certifications, and, when in doubt, homemade alternatives to keep your plate free from unwanted gluten.
