Keto Collagen Protein Bread (Low-Carb, High-Protein & Gluten-Free)

If you’ve ever tried keto or low-carb baking, you already know the struggle: breads that are dense, eggy, crumbly, or just don’t feel like real bread. That’s exactly why this Keto Collagen Protein Bread is such a game-changer.

This loaf is soft yet sturdy, light but satisfying, and packed with protein thanks to collagen peptides. It’s completely gluten-free, low in carbs, and incredibly versatile — perfect for toast, sandwiches, or a warm slice with butter. Best of all, it doesn’t rely on complicated techniques or obscure ingredients.

Whether you’re keto, low-carb, gluten-free, or simply looking to boost protein intake in a clean, wholesome way, this bread belongs in your kitchen.

Why Collagen Protein Bread Is Different

Unlike traditional keto breads that rely heavily on cheese or eggs, collagen protein bread uses collagen peptides as a structural and nutritional powerhouse.

Benefits of Using Collagen in Bread:

• Adds high-quality protein without carbs
• Improves bread structure and softness
• Neutral flavor — no overpowering taste
• Naturally gluten-free
• Supports joints, skin, and gut health

Combined with almond flour and eggs, collagen creates a loaf that slices cleanly, holds toppings beautifully, and actually feels like bread.

What This Bread Tastes Like

This bread has a mild, neutral flavor — slightly nutty from almond flour, rich from eggs, and buttery if you choose that fat option. There’s no sweetness, making it ideal for both savory and lightly sweet toppings.

Texture-wise, it’s:

• Soft in the center
• Lightly crisp on the outside
• Moist but not gummy
• Sliceable without crumbling

In other words: sandwich-worthy.

Ingredients

• Eggs
• Collagen peptides powder (unflavored)
• Almond flour (fine, blanched)
• Baking powder
• Apple cider vinegar
• Olive oil or melted butter
• Salt

That’s it — no yeast, no gluten, no sugar.

Instructions

1. Preheat the oven to 350°F (175°C). Line a loaf pan with parchment paper.
2. Separate eggs into whites and yolks.
3. Whip egg whites in a clean bowl until stiff peaks form. Set aside.
4. Mix yolks with olive oil (or butter), apple cider vinegar, and salt until smooth.
5. Add dry ingredients: almond flour, collagen peptides, and baking powder. Mix until thick and well combined.
6. Fold in egg whites gently, one third at a time, to keep the batter airy.
7. Transfer batter to prepared loaf pan and smooth the top.
8. Bake for 35–40 minutes until golden and a toothpick comes out clean.
9. Cool completely before slicing for best texture.

• If your oven runs hot, tent loosely with foil halfway through baking.
