Are Flour Tortillas Gluten-Free?

From The New Day Notebook · Facts last checked October 21, 2026 · General information, not medical advice

No, traditional flour tortillas are not gluten-free. The name itself points to the key ingredient: wheat flour. Since wheat is one of the main sources of gluten, standard flour tortillas are unsuitable for anyone on a strict gluten-free diet.

This means many popular dishes that rely on large, flexible tortillas are off-limits unless a safe alternative is used. Fortunately, the growing demand for gluten-free options has made it easier to find suitable swaps in grocery stores and restaurants.

Flour tortillas and gluten at a glance

Why flour tortillas contain gluten

The core ingredient in a classic flour tortilla is wheat flour. Wheat contains proteins that form gluten when mixed with water, which gives the tortillas their characteristic soft, pliable texture. This is why they can be folded and rolled without breaking. Because wheat is the primary ingredient, these tortillas are a significant source of gluten.

Flour tortillas are recognized by organizations like the Celiac Disease Foundation as a food that commonly contains gluten. Unless a tortilla is specifically made with an alternative flour and explicitly labeled gluten-free, it is safest to assume it is made from wheat and contains gluten.

Where to look for flour tortillas

Flour tortillas are the foundation of many popular dishes, especially in Mexican and Tex-Mex cuisine. You will need to be careful with items like burritos, wraps, and quesadillas, as these are almost always made with wheat tortillas. Fajitas are often served with a stack of warm flour tortillas on the side for filling.

When eating out, always ask what kind of tortillas are used in a dish. Even if a filling is gluten-free, the wrap or tortilla itself will introduce gluten. Cross-contamination is also a risk in restaurant kitchens. Surfaces used to prepare flour tortillas, like grills or cutting boards, can transfer gluten to otherwise safe foods. Shared fryers are another common problem, as flour tortillas are sometimes fried to make chimichangas or crispy taco salad bowls.

Gluten-free alternatives that work

Finding a good substitute for flour tortillas is straightforward. The most traditional and widely available option is the corn tortilla. Made from masa harina, or corn flour, corn tortillas are naturally gluten-free and are the classic choice for tacos. Always check the packaging to ensure they are not made with a blend of corn and wheat flour.

Many companies now produce tortillas specifically labeled as gluten-free. These are often made from a blend of alternative flours such as rice, tapioca, or almond flour to mimic the soft texture of a wheat tortilla. In the United States, federal regulations require that any food labeled “gluten-free” must contain fewer than 20 parts per million of gluten. Reading labels carefully is the most reliable way to find a safe and delicious replacement.

When to loop in your doctor or dietitian

If you suspect you have a medical reason for avoiding gluten, such as celiac disease, consult a doctor for proper testing. It is important to continue eating a normal diet containing gluten until all testing is complete, as removing it beforehand can lead to inaccurate results. For personalized dietary management, a registered dietitian can provide expert guidance.

• If you think gluten is making you unwell, ask about celiac disease testing before cutting gluten out: testing needs gluten in the diet
• If you have celiac disease and still have symptoms on a gluten-free diet
• If you are unsure whether oats, wheat starch or a specific ingredient suits you
• For help planning a gluten-free diet that still meets your nutrition needs
