Prep 15 min Cook 45 min Total 3h Level Intermediate
Serves 12

Ingredients

Dry Ingredients

  • 1.5 cups Blanched almond flour — Must be finely ground, not almond meal
  • 0.5 cups Golden flaxseed meal — Use golden, not brown, for a lighter color and milder flavor
  • 1 tablespoon Baking powder — Ensure it is fresh for maximum lift
  • 0.5 teaspoon Salt — Fine sea salt

Wet Ingredients

  • 5 whole Large eggs — Room temperature
  • 0.33 cup Unsalted butter — Melted and slightly cooled (can sub coconut oil)
  • 1 tablespoon Apple cider vinegar — Reacts with baking powder for extra lift
  • 0.25 cup Warm water — Helps activate the flaxseed

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8x4 inch loaf pan with parchment paper, leaving an overhang on the long sides for easy removal. Lightly grease the exposed ends of the pan.

    ~5 min
    Using an 8x4 pan instead of a 9x5 will force the bread to bake taller, giving you a better sandwich slice.
  2. In a medium bowl, whisk together the finely ground almond flour, golden flaxseed meal, baking powder, and salt. Ensure there are no lumps in the almond flour.

    ~3 min
    Sifting the almond flour can further prevent a dense crumb.
  3. In a large mixing bowl, beat the room temperature eggs with a whisk or electric mixer on medium-high speed for about 2 minutes until very frothy and pale. This incorporates air, which is crucial for a light texture.

    ~3 min
    Do not skip beating the eggs; this is the primary structural lift for gluten-free keto bread.
  4. Lower the mixer speed and slowly pour in the melted butter, apple cider vinegar, and warm water. Mix until just combined.

    ~2 min
  5. Gently fold the dry ingredients into the wet ingredients using a spatula. Mix until no dry spots remain, being careful not to over-stir and deflate the eggs.

    ~2 min
  6. Allow the batter to rest in the bowl for 5 minutes. The flaxseed meal will absorb the liquid and thicken the batter significantly.

    ~5 min
  7. Pour the thickened batter into the prepared loaf pan, smoothing the top with a spatula.

    ~2 min
    You can sprinkle seeds (like sesame or sunflower) on top at this stage if desired.
  8. Bake on the middle rack for 40-45 minutes. The bread is done when the top is golden brown, firm to the touch, and a toothpick inserted into the center comes out clean.

    ~45 min
    If the top is browning too quickly at the 30-minute mark, tent it loosely with aluminum foil.
  9. Remove the pan from the oven and let it cool for 15 minutes. Then, use the parchment overhang to lift the bread out of the pan. Transfer it to a wire cooling rack and allow it to cool completely before slicing.

    ~2h
    Cutting into keto bread while it is still warm will result in a gummy, dense texture. Complete cooling allows the crumb structure to set.

Equipment
  • 8x4 inch loaf pan
  • Parchment paper
  • Mixing bowls
  • Whisk
  • Electric hand mixer (optional)
Tips & Storage
  • Always use room temperature eggs. Cold eggs will cause the melted butter to seize and create a lumpy, dense batter.
  • For the lightest color and least 'earthy' flavor, stick to golden flaxseed meal over brown.
  • Slice the bread with a serrated bread knife using a gentle sawing motion to keep the crumb intact.
  • Toast slices before making a sandwich; toasting gives the keto bread a firmer structure and better mouthfeel.
  • Storage: Store the fully cooled bread in an airtight container or zip-top bag in the refrigerator for up to 1 week. For longer storage, slice the loaf and freeze with parchment paper between slices in a freezer-safe bag for up to 3 months. Toast directly from frozen.
