Welcome back to the kitchen! If you’ve been searching for a bread alternative that actually fits into a healthy lifestyle without sacrificing that classic, satisfying texture, you are in for a treat. I’ve spent quite a bit of time perfecting this Low Carb Flax Bread, and it has quickly become my absolute go-to for everything from morning toast to hearty midday sandwiches. It’s dense, nutritious, and incredibly easy to whip up, making it the perfect solution for anyone looking to keep their macros in check while still enjoying a proper slice of bread. Let’s dive into how you can bake this high-protein loaf right in your own kitchen!

  • 200 g ground flax seeds
  • ½ cup psyllium husk powder
  • 1 tablespoon baking powder
  • 1 ½ cups soy protein isolate
  • ¼ cup granulated Stevia
  • 2 teaspoons salt
  • 7 large egg whites
  • 1 large whole egg
  • 3 tablespoons butter
  • ¾ cup water
  • Preheat your oven to 350°F (175°C) and prepare a standard bread pan by greasing it thoroughly with butter or non-stick spray.
  • In a large mixing bowl, combine 200 g (7.05 oz) of ground flax seeds, ½ cup (45 g / 1.59 oz) of psyllium husk powder, 1.5 cups (150 g / 5.29 oz) of soy protein isolate, 1 tbsp (15 g / 0.53 oz) of baking powder, ¼ cup (48 g / 1.69 oz) of granulated Stevia, and 2 tsp (12 g / 0.42 oz) of salt.
  • In a separate medium bowl, whisk together 1 large whole egg, 7 large egg whites, 3 tbsp (42 g / 1.48 oz) of melted butter, and ¾ cup (177 ml / 6.0 oz) of water until the mixture is completely smooth and well-combined.
  • If you wish to customize the flavor, this is the stage to stir in any desired extracts or sugar-free syrups into the wet ingredients.
  • Gradually pour the wet ingredient mixture into the dry ingredients while mixing continuously with a spatula or whisk until a thick, uniform dough forms.
  • Transfer the dough into your prepared bread pan, smoothing the top with the back of a spoon to ensure even baking.
  • Bake for 15.0 to 20.0 minutes, or until the loaf is set and a toothpick inserted into the center comes out clean.
  • Allow the bread to cool in the pan for at least 10 minutes before transferring it to a wire rack to cool completely before slicing.

Pro Tips for the Perfect Loaf

  • Don’t Skip the Sifting: To ensure your High Protein Bread Recipe doesn’t have clumps, sift the psyllium husk and soy protein isolate before mixing. This results in a much smoother, professional-grade crumb.
  • Use Room Temperature Eggs: For the best rise and emulsification, take your eggs out of the fridge 30 minutes before baking. This helps the wet ingredients incorporate perfectly with the Flax Seed Meal Bread base.
  • Let It Rest: Flax and psyllium are highly absorbent. Allow the batter to sit for about 2 minutes before pouring it into the pan; this gives the fibers time to hydrate, leading to a sturdier Keto Sandwich Bread.
  • Watch the Timer: Because this bread is high in protein and fiber, it can dry out quickly. Start checking for doneness at the 15-minute mark to keep the center moist and tender.

Frequently Asked Questions (FAQ)

Can I substitute the soy protein isolate with whey protein? While you can substitute it, soy protein isolate generally provides a more “bread-like” structure and holds moisture better than whey. If you use whey, your Keto Flaxseed Bread may be slightly airier and more prone to shrinking after it leaves the oven.

How do I store this bread to keep it fresh? Because this is a Gluten-Free Low Carb Bread, it does not contain preservatives. It is best stored in an airtight container in the refrigerator for up to 5 days, or sliced and frozen for up to 3 months.

Why did my bread turn out purple? Some brands of psyllium husk powder can react with baking powder and turn a slight purple or grey hue during baking. This is completely safe to eat and doesn’t affect the flavor of your Healthy Low Carb Breakfast toast!
