High-Protein Gluten-Free Bread Flour Blend (Wheat-Free Alternative to Caputo Fioreglut)

Looking for the best homemade gluten-free bread flour blend? This high-protein gluten free flour blend is easy to make, completely wheat-free, and perfect for soft sandwich bread, chewy pizza dough, dinner rolls, cinnamon rolls, and more.
If you’ve ever been disappointed by dense, crumbly gluten-free bread, you’re not alone. After years of gluten free baking, I’ve tested countless flour blends and bread recipes. While many all-purpose gluten-free flour blends work well for cookies and cakes, they often fall short when it comes to yeast baking.
That’s why I created this homemade gluten free bread flour blend.
Made with white rice flour, potato starch, tapioca starch, xanthan gum, and extra whey protein isolate, this blend delivers the structure, chew, and softness that many gluten free bread recipes lack. Even better, it’s completely wheat-free, making it a fantastic option for those with celiac disease, wheat allergies, or anyone who prefers to avoid wheat-derived ingredients.
Whether you’re making sandwich bread for school lunches, pizza night with the family, or homemade dinner rolls for the holidays, this flour blend is about to become a staple in your pantry.

A Great Alternative to Caputo Fioreglut and King Arthur Gluten Free Bread Flour
One thing that makes this recipe unique is that it contains no wheat starch.
Many popular gluten-free bread flours, including Caputo Fioreglut and King Arthur Gluten Free Bread Flour, use gluten-free wheat starch to help mimic the texture and elasticity of traditional wheat bread.
While gluten free, wheat starch is considered safe for many people with celiac disease, some individuals prefer to avoid wheat-derived ingredients altogether. Additionally, those with wheat allergies generally cannot use products containing wheat starch.
This homemade gluten free bread flour blend is completely wheat-free while still producing excellent results in yeast baking.
Instead of relying on wheat starch, this blend uses a combination of white rice flour, potato starch, tapioca starch, xanthan gum, and a generous amount of whey protein isolate to create structure, softness, and chew.
As someone who has followed a strict gluten free diet for years and is highly sensitive to cross-contamination, I appreciate knowing exactly what goes into my flour blend. Every ingredient can be sourced from trusted gluten-free brands, giving you complete control over what you’re feeding your family.
The Secret to Better Gluten Free Bread
The ingredient that truly transforms this recipe is whey protein isolate.
Many homemade gluten-free flour blends use very little protein, relying mostly on starches. While starches contribute softness, too much can create bread that feels gummy, fragile, or overly dense.
After experimenting with several versions, I found that increasing the whey protein isolate to 1½ cups dramatically improved the final product.
The additional protein helps:
- Improve rise
- Create a softer crumb
- Increase chewiness
- Improve browning
- Reduce gumminess
- Strengthen dough structure
- Produce more bakery-style results
This is why I consider this a high-protein gluten free bread flour blend rather than a traditional gluten-free flour mix.
The result is bread that feels much closer to traditional wheat bread than many gluten-free alternatives.
Gluten Free Bread Flour Blend Recipe
Ingredients
- 3¾ cups superfine white rice flour
- 1 cup + 2 tablespoons potato starch
- ½ cup + 1 tablespoon tapioca starch
- 3 tablespoons xanthan gum
- 1½ cups unflavored whey protein isolate
Instructions
- Add all ingredients to a large mixing bowl.

- Store in a cool, dry location.
Yield
Approximately 7 cups of gluten-free bread flour blend.
What Each Ingredient Does
White Rice Flour
White rice flour provides the base structure of the blend while maintaining a neutral flavor that works well in bread and pizza dough.
Potato Starch
Potato starch helps retain moisture and creates a softer texture.
Tapioca Starch
Tapioca starch contributes elasticity and chew, making it especially important for pizza crust and yeast breads.
Xanthan Gum
Xanthan gum acts as a binder and helps hold the dough together.
Whey Protein Isolate
Whey protein isolate improves structure, rise, softness, and browning while helping mimic some of the characteristics of gluten.
What Can You Make with This Flour Blend?
Gluten-Free Sandwich Bread
This flour blend was originally developed for homemade sandwich bread.
Combined with psyllium husk, yeast, eggs, and warm water, it produces a soft loaf with a tender crumb and excellent sliceability.
This is one of my favorite uses for this blend.
The combination of whey protein isolate and psyllium husk creates a dough that develops chew and structure while maintaining a crisp crust.
If you’ve been searching for a homemade gluten-free pizza dough recipe that doesn’t crumble apart, this flour blend is the perfect place to start. And it toasts beautifully without making the crust hard.
Dinner Rolls
Soft, fluffy dinner rolls are finally possible without wheat starch.
The added protein helps create dough that can be rolled, shaped, and baked into soft cinnamon rolls.
Hamburger Buns
This flour blend works beautifully for homemade gluten-free hamburger buns and sandwich rolls.
Tips for Success
Use Psyllium Husk for Bread Recipes
While the flour blend provides structure, psyllium husk adds flexibility and elasticity.
For most bread recipes, I recommend using approximately 2 tablespoons of psyllium husk powder per loaf.
Measure Carefully
For the most consistent results, weigh ingredients whenever possible.
Allow Bread to Cool Completely
Gluten-free bread continues setting as it cools. Slicing too soon can create a gummy texture.
Store Properly
- Counter: 2–3 days
- Refrigerator: Up to 1 week
- Freezer: Up to 3 months
I prefer slicing loaves before freezing for easy grab-and-go use.
