The Traditional French Choice: Type 55 (T55) Flour
For centuries, French bakers have relied on a specific flour classification system to achieve the distinct characteristics of their breads. The most traditional flour used for French bread, particularly the classic baguette, is Type 55 (T55) flour. This European flour has a lower protein content than typical American bread flour, usually around 11.5%, which is crucial for achieving the classic French baguette's delicate, open crumb and perfectly crisp, crackly crust.
In France, the 'T' number refers to the flour's mineral content, or 'ash content.' A lower number indicates a whiter, more refined flour. T55 flour, with its moderate ash content, strikes the perfect balance for traditional lean breads, which are made only with flour, water, yeast, and salt. Its properties give the dough enough elasticity to rise beautifully, but not so much that it becomes overly chewy or dense, which is a common pitfall when using higher-protein flours.
American Flour Substitutes for Home Bakers
Since authentic French T55 flour is not widely available outside of specialty stores, most home bakers rely on American alternatives. Two common options are unbleached all-purpose flour and artisan bread flour. While they differ from T55, careful technique can produce exceptional results.
Using All-Purpose Flour
Many French bread recipes for home bakers call for unbleached all-purpose (AP) flour. AP flour has a moderate protein content that is often comparable to T55, making it a viable substitute. Using a high-quality, unbleached AP flour like King Arthur or Bob's Red Mill can yield a delicious loaf with a good balance of chew and tenderness. However, since the protein content can vary by brand, pay attention to the dough's texture and adjust the flour or water as needed during mixing and kneading. Some bakers find AP flour produces a stickier dough that can be harder to handle during shaping.
Opting for Bread Flour
Bread flour has a higher protein content (often 12-14%) than both T55 and most all-purpose flours, which means it develops more gluten. This can result in a taller, chewier bread with a more robust structure. For bakers who prefer a chewier crumb, or those looking for a slightly more forgiving dough, bread flour is an excellent choice. While it won't replicate the delicate texture of a traditional baguette precisely, it can still produce a fantastic, crusty loaf. You can even create a custom flour blend by mixing half AP flour and half bread flour to find a middle ground. To get the best results with bread flour, it is often recommended to use techniques that promote an open crumb, such as a high hydration dough and careful handling.
Flour Comparison for French Bread Baking

| Artisan Bread Flour | 11.5-13% | Higher protein content, strong gluten development, excellent for high-hydration doughs. | Chewier, taller breads with a more robust structure and open crumb. | Many grocery stores, online retailers. |
| King Arthur Sir Galahad | 11.7% | Professional-grade flour, handles high hydration well, known for consistent performance. | High-quality baguettes and artisan loaves, easy substitution for T55. | Professional baking suppliers, some online retailers. |
Techniques for the Best French Bread
No matter what flour you choose, mastering the technique is vital for that signature French bread texture. Many recipes use a pre-ferment, or 'poolish,' which is a wet starter made with flour, water, and yeast that ferments overnight. This adds significant depth of flavor and contributes to a beautiful open crumb. High hydration doughs, meaning a higher ratio of water to flour, are also essential for an airy interior. Other secrets include steam in the oven to create the crisp, crackly crust and using a baking stone or preheated Dutch oven for even heat distribution.
- Use a scale: Measuring flour by weight, not volume, is the most accurate method for consistent baking, especially with high-hydration doughs.
- Gentle handling: Over-kneading can result in a dense crumb. Techniques like stretch-and-fold are ideal for developing gluten gently.
- Long, slow fermentation: An overnight rise in the refrigerator, known as cold fermentation, significantly improves the flavor complexity of the final loaf.
- Create steam: Placing a pan of water in the oven when you bake helps to create steam, which keeps the crust soft during the initial bake, allowing for maximum oven spring and a crisp finish.
Conclusion: Your Flour Choice and Technique Matter
Ultimately, the type of flour used for French bread plays a significant role in the final result. While the authentic T55 flour is the gold standard for traditional baguettes, home bakers can achieve remarkable success with widely available options like unbleached all-purpose or artisan bread flour. Understanding the differences in protein content and adjusting your techniques accordingly—such as using high hydration and a slow fermentation—will allow you to craft a delicious loaf with a characteristically crisp crust and airy interior. By paying attention to both ingredients and method, you can bake delicious, artisan-quality bread right in your own kitchen.

French Bread Flour FAQs
Q: Can I use all-purpose flour for French bread? A: Yes, you can. While it may not produce the exact texture of a traditional baguette made with T55, a high-quality unbleached all-purpose flour is a common and effective substitute for home bakers.
Q: What is the difference between T55 flour and American all-purpose flour? A: T55 flour is a French designation indicating a specific mineral (ash) content and typically has a protein content around 11.5%. American AP flour can vary in protein content by brand, but many are comparable, though T55 is often considered softer and better for achieving an open crumb.
Q: Is bread flour a good substitute for T55 flour? A: Bread flour has a higher protein content (12-14%) than T55, leading to more gluten development. This will produce a chewier, denser loaf, rather than the light, delicate crumb of a traditional baguette, but can still create a delicious bread.
Q: How can I improve the result when using all-purpose flour? A: To get a better result with all-purpose flour, consider adding a tablespoon of vital wheat gluten to boost the protein content. Using a pre-ferment (poolish) and a high-hydration dough, combined with proper shaping, will also help.
Q: What is ash content in flour? A: Ash content refers to the percentage of minerals remaining after a sample of flour is burned. The number indicates how much of the outer wheat kernel (bran and germ) is left; a higher number means a darker, more whole-grain flour, while a lower number indicates a whiter, more refined flour.
Q: What are some high-quality American flour brands for French bread? A: For an authentic taste and texture, brands like King Arthur Sir Galahad or Bob's Red Mill Artisan Bread Flour are excellent professional-grade options. Standard King Arthur or Bob's Red Mill all-purpose flour are also great choices.
Q: Does flour brand really matter for French bread? A: Yes, especially since protein content can vary significantly between brands. Recipes often call for specific brands because of their known protein levels. Using a high-quality, consistent flour is a key step towards achieving great results.
