Ingredients
  

  • Keto sourdough discard (3/4 cup), fed with low-carb ingredients like almond flour, flax meal, or a specialty low-carb blend
  • Almond flour (2 cups, fine blanched)
  • Ground psyllium husk (2 tablespoons)
  • Baking powder (2 teaspoons, aluminum-free)
  • Sea salt (1/2 teaspoon)
  • Eggs (4 large, room temperature)
  • Olive oil or melted butter (1/4 cup)
  • Apple cider vinegar (1 teaspoon)
  • Warm water (2–4 tablespoons, as needed)
  • Optional flavor boosters: garlic powder, dried rosemary, everything bagel seasoning, shredded Parmesan, sesame seeds

Instructions
 

  • Preheat and prep: Heat the oven to 350°F (175°C). Line a 9x5-inch loaf pan with parchment and lightly grease the sides.
  • Mix dry ingredients: In a large bowl, whisk almond flour, psyllium husk, baking powder, and salt until evenly combined.
  • Whisk the wet: In a separate bowl, whisk eggs, olive oil (or butter), apple cider vinegar, and the keto sourdough discard. The mixture should look smooth and slightly foamy.
  • Combine: Pour wet into dry and stir with a spatula until just combined. If the batter seems too thick or dry, add warm water 1 tablespoon at a time. You’re aiming for a thick, spreadable batter, not a dough.
  • Flavor it up (optional): Fold in herbs, garlic powder, or 1/4 cup grated Parmesan. Sprinkle the top with sesame or everything seasoning for a bakery look.
  • Pan and smooth: Transfer batter to the loaf pan. Smooth the top with a damp spatula to prevent cracking.
  • Bake: Bake for 38–45 minutes, until the top is golden and a toothpick comes out mostly clean with a few moist crumbs.
  • Cool completely: Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack. Cool at least 45 minutes before slicing for best texture.
  • Slice and serve: Slice into 10–12 pieces. Toast slices in a skillet with butter or in a toaster oven for the best flavor and crumb.
