A hearty 8-inch protein bread loaf made entirely without oats or gluten. This recipe uses white rice flour, potato starch, and tigernut flour as the base, with banana-flavored pea protein isolate for clean plant-based protein. Milled flaxseed, chia seeds, acacia fiber, and PHGG provide exceptional prebiotic fiber and binding without any gluten. Sweetened only with monkfruit/erythritol blend, this bread is completely sugar-free and dairy-free. The 1.5x scaled batter bakes into a beautiful loaf with a well-browned, springy top. For a resistant starch (RS3) boost, wrap and refrigerate the loaf overnight before slicing — the retrograded starches feed beneficial gut bacteria and improve blood sugar response. Toast or rewarm slices as desired. Perfect for those following celiac, AIP-adjacent, or grain-sensitive protocols who still want satisfying, protein-enriched bread. Each slice delivers quality plant protein with sustained energy from complex carbohydrates and healthy fats. Pairs beautifully with nut butter, avocado, or simply enjoyed on its own.

INSTRUCTIONS
Preheat your oven to 375°F (190°C). No initial high-heat blast is needed for a loaf. Line an 8-inch loaf pan with parchment paper or grease well with coconut oil.
Whisk all dry ingredients together very thoroughly in a large bowl. The glucomannan and PHGG must be evenly dispersed throughout the flour mixture to ensure proper binding without gluten. Sift the rice flour and potato starch first for the smoothest texture.
Mash the bananas thoroughly (360g by scale). Whisk in applesauce or pumpkin puree, eggs, monkfruit sweetener, vanilla, and 315ml plant milk. Pour wet into dry and fold gently until just combined. Rest 3-5 minutes so fibers and protein hydrate. The batter will be thick but should still pour with help of a spatula. If too thick, fold in up to 30ml more plant milk.
Pour batter into prepared pan and smooth the top. Bake at 375°F/190°C for 40-50 minutes. Start checking at 38-40 min — loaf is done when a skewer comes out mostly clean from the center and the top is well browned and springs back when pressed. Cool in pan 15-20 minutes, then lift out to a rack until fully cool.
For maximum gut health benefits, wrap the cooled loaf and refrigerate overnight (at least 12 hours) before slicing. This retrograde process converts some starches into RS3 resistant starch, which feeds beneficial gut bacteria. Toast or briefly rewarm slices as desired.
TROUBLESHOOTING
My breads are too dry
Try adding 1-2 tablespoons more liquid (milk, yogurt, or egg whites). Also ensure you're not over-measuring the protein powder - use the scoop and level method.
They didn't rise properly
Check your baking powder is fresh (test by adding to hot water - it should bubble vigorously). Also, don't overmix the batter as this can deflate the air bubbles.
The texture is rubbery
This usually means too much protein powder or overbaking. Reduce baking time by 2-3 minutes and check doneness with a toothpick.
