Brief Introduction

This Keto Sourdough Bread captures the tang and heartiness of real sourdough in a keto-friendly way. The combination of apple cider vinegar, yogurt, and flax gives it that signature sourdough tang while keeping it gluten-free and low-carb. Perfect for those who miss artisan bread but want to stay on track.

Step-by-Step Cooking Guide

Step 1 – Tangy Base: Apple cider vinegar and yogurt simulate sourdough starter flavor.
Step 2 – Structure: Almond flour + coconut flour keep the loaf sturdy without gluten.
Step 3 – Golden Bake: Patience — allow cooling for slices to firm up.

Ingredient Details & Substitution Tips

Almond Flour: Must be superfine; avoid almond meal for texture.
Coconut Flour: Helps absorb moisture; don’t skip it.
Flaxseed Meal: Adds chew and nutty depth; can swap with chia seed meal.
Apple Cider Vinegar: Gives sour tang; white vinegar works in a pinch.
Greek Yogurt: Adds tang + structure; can sub with sour cream or dairy-free yogurt.

Variations & Serving Suggestions

Herbed Version: Add rosemary, thyme, or garlic powder for a savory loaf.
Seeded Sourdough: Sprinkle sesame, sunflower, or pumpkin seeds on top before baking.
Serving Ideas:
- Toasted with butter and keto jam 🧈🍓
- For avocado toast 🥑
- As sandwich bread for keto grilled cheese 🧀
- With soups and stews 🍲

Storage & Make-Ahead Info

Fridge: Store sliced bread in airtight container for 5–6 days.
Freezer: Freeze slices individually, then toast straight from freezer.
Reheat: Best crisped in toaster or skillet with butter.

FAQs

Q: Can I make this dairy-free?
A: Yes — replace butter with coconut oil and Greek yogurt with unsweetened coconut yogurt.

Q: Why does my bread fall apart?
A: Let it cool completely before slicing; warm keto breads crumble easily.

Q: Can I get a real sourdough starter for keto bread?
A: Traditional starters rely on flour, but some keto bakers use whey protein or coconut flour “starters.” This recipe uses vinegar + yogurt for reliable flavor without the fuss.

Personal Note

This bread was a total game-changer for me on keto. The sourdough tang makes it taste like “real bread,” and it holds up beautifully for toast and sandwiches.
