Orkney thin oatcakes are a crisp, delicate Scottish flatbread made from just oatmeal, salt, and water, baked until golden and brittle. Unlike thicker commercial oatcakes, these are rolled paper-thin and dry out completely in the oven, giving them a satisfying snap and a deep, toasty oat flavor. They are the perfect vehicle for butter, cheese, or smoked fish, and this recipe replicates the traditional method with simple ingredients you can find anywhere.
Ingredients
- 2 cups (200 g) fine or medium oatmeal (not instant oats), plus extra for dusting
- 1/2 tsp (3 g) fine sea salt
- 3/4 cup (180 ml) boiling water, plus more if needed
- 1 tbsp (15 ml) melted butter or bacon fat (optional, for richness)
- Oat flour or additional oatmeal for rolling
Instructions
- Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
- In a large bowl, mix the oatmeal and salt together. Pour in the boiling water and the melted butter (if using). Stir with a wooden spoon until the mixture comes together into a stiff, slightly sticky dough. If it seems too dry and crumbly, add another tablespoon of boiling water. If it is too wet, add a little more oatmeal.
- Turn the dough out onto a surface generously dusted with oat flour or extra oatmeal. Knead gently 2-3 times until smooth. The dough will be very sticky, so keep dusting.
- Divide the dough into two equal portions. Keep one covered with a damp cloth while you work with the other.
- Roll the dough out as thinly as possible, aiming for about 1/8 inch (3 mm) thick, or even thinner if you can manage it. Keep dusting the surface and the rolling pin to prevent sticking. If the dough tears, just press it back together—it will not affect the final texture.
- Using a sharp knife or a pastry cutter, cut the rolled dough into triangles or squares, about 2 inches (5 cm) across. Traditional Orkney oatcakes are cut into triangles.
- Carefully transfer the cut oatcakes to the prepared baking sheets, leaving a small gap between each. They will not spread much.
- Bake for 15-20 minutes, rotating the sheets halfway through, until the oatcakes are lightly golden at the edges and feel completely dry and firm. They should snap when broken, not bend.
- Transfer the oatcakes to a wire rack to cool completely. They will crisp up further as they cool. Repeat with the remaining dough.
Tips
- Use the right oatmeal: Traditional Orkney oatcakes use coarse or medium pinhead oatmeal, which gives a rustic texture. If you only have rolled oats, pulse them in a food processor a few times until they resemble coarse flour. Do not use instant oats, as they will make a gummy dough.
- Roll thin and even: The key to a crisp oatcake is rolling the dough very thin. If some areas are thicker, they will be chewy in the middle. Use a ruler or just eyeball it—the thinner, the better.
- Keep the dough covered: Oatmeal dough dries out quickly. Keep the portion you are not rolling under a damp towel to prevent cracking at the edges.
- Don’t overbake: Oatcakes go from golden to burnt quickly. Start checking at 12 minutes. They should be a pale biscuit color, not dark brown, unless you prefer a stronger toasted flavor.
Serving Suggestions
Orkney thin oatcakes are traditionally served with butter and a slice of mature cheddar or crumbly blue cheese. They also pair beautifully with smoked salmon, herring, or a dollop of cream cheese and chives. For a sweet twist, spread with honey or raspberry jam. They are also excellent alongside soups, stews, or a cheese board.
Variations
- Seeded oatcakes: Add 1 tablespoon of sesame seeds, poppy seeds, or caraway seeds to the dry ingredients before adding water.
- Herb oatcakes: Mix in 1 teaspoon of dried thyme, rosemary, or chives for a savory flavor that goes well with soft cheeses.
- Whole wheat oatcakes: Replace half of the oatmeal with whole wheat flour for a slightly softer, less gritty texture.
- Gluten-free: This recipe is naturally gluten-free if you use certified gluten-free oatmeal. Ensure your baking powder (if using) is also gluten-free.
Storage and Reheating
Store the cooled oatcakes in an airtight container at room temperature for up to 1 week. They will stay crisp if kept dry. Do not refrigerate, as they will absorb moisture and become soft. If they do soften, re-crisp them in a 300°F (150°C) oven for 5 minutes. Oatcakes freeze well for up to 3 months in a sealed freezer bag; thaw at room temperature and re-crisp in the oven before serving.
Frequently Asked Questions
Can I use quick-cook oats instead of oatmeal? Quick-cook oats are too finely ground and will produce a dense, gummy dough. Use medium or coarse oatmeal for the authentic texture. If you only have rolled oats, pulse them briefly in a food processor to break them down.
Why are my oatcakes soft and chewy? This usually happens when the dough is rolled too thick or the oatcakes are underbaked. Roll to 1/8 inch (3 mm) or less and bake until they are completely dry and firm to the touch. They will also crisp up as they cool, so do not remove them from the oven too early.
Can I make the dough ahead of time? Yes, you can prepare the dough, wrap it in plastic, and refrigerate for up to 2 days. Let it come to room temperature for 15 minutes before rolling, as cold dough will be harder to roll thin.
What is the difference between Orkney oatcakes and Scottish oatcakes? Orkney oatcakes are traditionally thinner and crisper than the thicker, softer Scottish oatcakes from the mainland. They are also often baked, whereas some regional versions are griddle-cooked.
Can I make these without butter? Yes, the butter is optional. Traditional Orkney oatcakes use only oatmeal, salt, and water. Omit the butter for a leaner version that is still delicious, though the texture will be slightly more brittle.
How do I know when they are done? The oatcakes should be lightly golden at the edges and feel completely dry and crisp. Break one to test—it should snap cleanly with no soft center. If it bends, bake for another 2-3 minutes.
