Yes, oatcakes are gluten free when made with certified gluten-free oats and no wheat flour. However, traditional oatcake recipes—especially Scottish and English versions—often include wheat flour, so you must check the label or ingredients before eating them if you have celiac disease or gluten sensitivity.
What Are Oatcakes?
Oatcakes are flat, unleavened or lightly leavened baked goods made primarily from oats. They come in two main forms: the crisp, cracker-like Scottish oatcake (similar to a biscuit) and the softer, griddle-cooked English oatcake (similar to a pancake). Both are made from oat flour or oatmeal mixed with water, salt, and often a little fat. Scottish oatcakes are typically baked in an oven, while English oatcakes are cooked on a hot griddle or frying pan. They are eaten as a snack, with cheese, or as a base for savory toppings.
Why Oats Are Naturally Gluten Free
Oats are a gluten-free grain by nature. The protein in oats—called avenin—is structurally different from the gluten found in wheat, barley, and rye, and it does not trigger the same immune response in most people with celiac disease. However, the issue is cross-contamination. Most commercial oats are grown, harvested, and processed in facilities that also handle wheat, barley, or rye, so they can easily become contaminated with gluten during farming or milling.
What Makes an Oatcake Not Gluten Free?
Two things can make an oatcake unsafe for a gluten-free diet:
- Wheat flour added to the recipe: Many traditional oatcake recipes, especially English versions, include wheat flour to help bind the dough and give a lighter texture.
- Cross-contamination of oats: Even if the recipe uses only oats, if those oats are not certified gluten-free, they may contain traces of wheat, barley, or rye from shared equipment or fields.
For example, a classic Scottish oatcake recipe might use only oats, salt, water, and fat—that is naturally gluten free. But a commercial oatcake brand may add wheat flour for crispness, so it is not safe for gluten-free diets.
How to Choose Gluten-Free Oatcakes
When shopping for oatcakes, follow these steps to ensure they are gluten free:
- Read the ingredient list: Look for “gluten-free oats” or “certified gluten-free” on the package. If wheat flour, barley malt, or rye is listed, the product is not gluten free.
- Check for a gluten-free certification label: Third-party certifications like the Gluten-Free Certification Organization (GFCO) or a simple “gluten-free” claim on the package indicate the product meets FDA standards (less than 20 parts per million of gluten).
- Look for “wheat-free” but be careful: A product can be wheat-free yet still contain barley or rye, so always check the full ingredient list.
- Ask at a bakery or restaurant: If you are buying fresh oatcakes, ask whether they use certified gluten-free oats and whether they are prepared in a dedicated gluten-free facility or on a dedicated surface.
Common Problems and Misconceptions
A common misconception is that all oat products are gluten free because oats are a gluten-free grain. This is false—most regular oats are contaminated with gluten during processing. Another issue is that some people with celiac disease react to avenin, the protein in oats, even when they are certified gluten-free. This is rare but real, so if you have celiac disease, it is best to introduce oats under medical supervision and monitor your symptoms.
Another problem is that “oatcake” can mean different things in different countries. If you are traveling or ordering online, clarify whether you are getting the Scottish crisp or the English griddle cake, as the latter often contains wheat flour.
Gluten-Free Oatcake Brands and Alternatives
Several brands produce gluten-free oatcakes, such as Nairn’s (which makes a gluten-free range) and Bob’s Red Mill (which sells gluten-free oat flour). If you cannot find a gluten-free oatcake, you can make your own at home using certified gluten-free oat flour, salt, water, and a little olive oil or butter. You can also substitute oatcakes with other gluten-free crackers like rice cakes or corn thins, though the texture and flavor will differ.
Cost and Availability
Gluten-free oatcakes are generally more expensive than regular oatcakes due to the cost of certified gluten-free oats and dedicated production facilities. A box of 6-8 oatcakes may cost $3–$6, compared to $2–$4 for regular ones. They are widely available in health food stores, gluten-free sections of supermarkets, and online retailers. In the UK, they are a common grocery item; in the US, they are more of a specialty product.
Frequently Asked Questions
Are all oatcakes gluten free?
No, not all oatcakes are gluten free. Many contain wheat flour, and even those made only with oats may be cross-contaminated with gluten. Always read the label and look for certified gluten-free oats.
Can I eat oatcakes if I have celiac disease?
Most people with celiac disease can safely eat oatcakes made with certified gluten-free oats. However, a small percentage of people with celiac disease react to avenin, the protein in oats, so it is advisable to consult your doctor before adding oats to your gluten-free diet.
What is the difference between Scottish and English oatcakes?
Scottish oatcakes are crisp, dry crackers baked in the oven, similar to a biscuit. English oatcakes are soft, griddle-cooked pancakes, often served with cheese or savory fillings. The English version more frequently contains wheat flour.
Are oats safe for a gluten-free diet?
Yes, oats are naturally gluten free, but only if they are certified gluten-free to avoid cross-contamination. Regular oats are often contaminated with wheat, barley, or rye during farming or processing.
How do I know if an oatcake is gluten free?
Check the ingredient list for “gluten-free oats” and look for a gluten-free certification on the package. If the product lists wheat flour, barley malt, or rye, it is not gluten free. When in doubt, contact the manufacturer.
Making Your Own Gluten-Free Oatcakes
If you prefer to make oatcakes at home, use certified gluten-free oat flour. A simple recipe combines 2 cups (200 g) oat flour, 1/2 teaspoon salt, 1 tablespoon (15 ml) olive oil or melted butter, and about 1/2 cup (120 ml) hot water. Mix to form a dough, roll it out thinly, cut into rounds, and bake at 350°F (175°C) for 15–20 minutes until crisp. This homemade version is naturally gluten free and lets you control the ingredients.
