Easy Low-Carb Keto Flax and Chia Seed Bread

Why I Love This Keto Seed Bread

If you’re looking for a simple, reliable low-carb, keto-friendly bread that doesn’t involve complicated flour substitutions, this chia and flax seed bread is a great place to start.

The recipe is easy to follow, it came out genuinely delicious, and it’s an awesome way to get more fiber and omega-3 fats into your diet. The texture is hearty and filling—more “dense seed bread” than “white sandwich loaf”—which is exactly what I want when I’m trying to stay low-carb.

Bonus: if you omit the sunflower seeds, this bread becomes extremely low carb—roughly ~4 net carbs for the entire loaf (depending on the ingredients you use and how you slice it).


Ingredients

  • 2 tbsp chia seeds + 4 tbsp water
  • 150 g flax seeds
  • 50 g sunflower seeds (toasted)
  • 1 tsp baking powder
  • A pinch of salt
  • 200 ml water
  • 1 tsp apple cider vinegar
  • Everything Bagel Seasoning (for topping)

Optional low-carb tweak: Skip the sunflower seeds to reduce carbs even further.


Directions

  1. Make the chia gel: Mix 2 tbsp chia seeds with 4 tbsp water and let it sit until it thickens.
  2. Mix dry ingredients: Combine flax seeds, toasted sunflower seeds, baking powder, and a pinch of salt.
  3. Add liquids: Stir in 200 ml water
  4. Combine: Add the chia gel and mix until everything is evenly incorporated.
  5. Flavorize: Form loaf into a ball shape, rub 1 tsp apple cider vinegar all over. Top with bagel seasoning
  6. Shape and top: Transfer to your baking pan or shape into a loaf, then sprinkle sesame seeds on top.
  7. Bake: Bake until set and firm throughout (oven times vary by pan size and thickness).
  8. Cool before slicing: Let it cool completely so it firms up and slices cleanly.

Tips for Best Results

  • Toast the sunflower seeds for better flavor and crunch.
  • Let it cool fully before slicing—this makes a huge difference in texture.
  • Slice thin and toast it if you want a more “bread-like” bite.
  • Store it properly: Keep it refrigerated to maintain freshness, or freeze sliced pieces for quick use.

Why This Bread is Great for Keto

  • Very low net carbs (especially if you omit sunflower seeds)
  • High fiber which helps with fullness and digestion
  • Healthy fats from flax and chia, including omega-3s
  • No flour, no sugar, and a simple ingredient list

A Great “Base Recipe” You Can Build On

One of the best things about this chia + flax bread is that it’s a solid foundation for experimentation. You can easily build on it with different keto-friendly add-ins like:

  • Garlic powder, onion powder, or Italian seasoning
  • Rosemary and sea salt
  • Parmesan or shredded cheddar (if your diet allows)
  • Chopped jalapeños or red pepper flakes for heat

If you try a variation, I’d love to hear what you added and how it turned out.


Final Thoughts

This is one of the easiest low-carb “bread” recipes I’ve made, and it’s a great option if you want something filling without blowing your carbs for the day. It’s hearty, nutrient-dense, and surprisingly tasty—especially toasted.
