Are you ready for the best low-carb yeast bread? This fluffy, keto-friendly and nut-free bread has been on my list for a while, and I’m excited to finally share it with you. Yes, there are no nuts! After some trial and error, I’ve created the perfect low-carb and keto yeast bread that tastes just like real bread.
I started working on this recipe in the summer of 2019, but life got busy. Between signing two new book deals and other projects, I took my time to make sure everything was just right. Now, after some testing and adjustments, it’s here, and I think you’re going to love it.
How to Make Keto Yeast Bread
Making low-carb yeast bread is easier than you may think. I already knew how to make Low-Carb Bread so I used the same recipe to start with and combined it with what I've learnt about yeast and how to use it in baking to get the best results.
Making low-carb yeast bread is easier than you might think! I started with my Low-Carb Bread recipe and then made a few tweaks to get the perfect fluffy texture using yeast. Here’s a quick breakdown of the ingredients you'll need and why each is important:
The Role of Ingredients
This recipe is naturally nut-free and uses a combination of flax meal, sesame flour, and coconut flour to create the ideal texture. Here's what you'll need to make keto yeast bread:
- Dry active yeast: This makes the bread rise and gives it that classic bread flavor. Make sure to use warm water (about 100°F/ 40°C) to activate the yeast properly.
- Inulin-based sweetener such as yacon syrup or sugar: Don’t worry—this is just to activate the yeast, and no sugar will be left after fermentation.
- Eggs and egg whites: Extra egg whites help keep the bread light and fluffy, and don’t worry—it won’t taste eggy.
- Apple cider vinegar: Adds a slight tang and works with baking soda to help the bread rise.
- Ground nuts and/or seeds: I use a mix of flax meal and sesame flour, which has a mild taste that works well with both sweet and savory spreads, including sugar-free jam and other tasty toppings like this Keto Nutella.
- Coconut flour. Adds texture without a coconut flavor when used in small amounts. You can replace it with flax meal, sesame flour, or more almond flour if needed.
- Psyllium husks, powdered: Key for a fluffy texture! Always powder whole husks yourself for the best results.
- Whey or egg white protein isolate: Replaces the gluten, helping to give the bread structure.
- Leavening agents: Use gluten-free baking powder or a mix of cream of tartar and baking soda.
- Other ingredients: Feel free to add things like salt, pepper, sesame seeds, herbs, or spices depending on your taste.
Important tip: For the best results, try not to swap out too many ingredients—especially the defatted sesame flour, which really helps with texture and taste.
The Role of Yeast in Keto Bread
You might be wondering why we use yeast in keto bread, especially since most keto recipes don’t include it. Yeast does more than just make dough rise; it adds flavor and creates air pockets, making the bread lighter and fluffier.
In traditional bread, yeast interacts with gluten to help with structure, but since we’re using gluten-free ingredients here, the effect isn’t exactly the same. Keto bread tends to be denser due to the fats in seeds, nuts, and coconut, but this recipe is one of the fluffiest you’ll find for low-carb bread.
We use powdered psyllium husks and whey (or egg white) protein isolate to replace gluten and give the bread structure. These ingredients are key to achieving a light texture that’s as close as possible to regular yeast bread.
Can I Use Fast-Acting Dried Yeast?
You can use fast-acting dried yeast (also called instant yeast), which doesn’t need to be activated in water first. Just mix it directly with the dry ingredients and don’t reduce the amount of water in the recipe. Just remember: always use dry active yeast or fresh yeast—not nutritional yeast, which won’t work in this recipe.
What if My Yeast Doesn't Foam?
If your yeast doesn’t foam, it means the yeast isn’t active, and the fermentation hasn’t started. Here are the main reasons this can happen:
- Water temperature issues: The water might have been too hot or too cold. The ideal temperature is around 100°F (40°C). If the water is too hot, it can kill the yeast; if it’s too cold, the yeast won’t activate.
- Expired yeast: Yeast is a living organism and can expire. Always check the expiration date and make sure the yeast is properly stored.
- Wrong sweetener: Yeast needs a certain type of sweetener to activate. Use inulin-based sweeteners like yacon syrup, or nutritive sweeteners like honey, maple syrup, or sugar. Don’t use low-carb sweeteners like erythritol, allulose or stevia, as these won’t work.

Recipe Swaps and Substitutions
I’ve tested several ingredient swaps to help you customize this recipe based on what you have available or your preferences. Here are some options that work well:
- Defatted sesame seed flour can be swapped for regular almond flour. Use about 2 cups (200 g) of almond flour to replace 1 1/4 cups (100 g) of sesame seed flour. If you’re using almond flour, reduce the amount of water to 1 1/2 cups (360 ml) to prevent the dough from getting too wet. This was the second best bread I've tested (first one is the recipe without swaps).
- Ground sesame seeds can also replace defatted sesame seed flour, but the dough may be slightly more moist. Use 1 packed cup (140 g) of ground sesame seeds to replace 1 1/4 cups (100 g) of defatted sesame flour. You may need to decrease the water to 1 1/2 - 1 3/4 cups to get the right consistency.
Tips: Because ground sesame seeds contain more fat, you can swap the egg yolks for additional egg whites. For one loaf, use a total of 8 egg whites instead of 3 egg yolks and 5 egg whites. Also, there’s a difference between hulled and unhulled sesame seeds—hulled seeds work better in this recipe.
- Coconut flour: If you want to skip coconut flour, you can replace it with three times the amount of almond flour or twice the amount of flax meal or ground sesame seeds. Just keep in mind, coconut flour is very absorbent, so you’ll need more of other flours to make up for it.
Detailed Baking Conversions for Defatted Sesame Flour
- 1 cup fine defatted sesame seed flour (80 g) = 1 cup fine defatted almond flour (120 g), plus you may need to reduce the amount of water by 1/4 to 1/2 cups (60 to 120 ml).
- 1 cup fine defatted sesame seed flour (80 g) = 2 cups regular almond flour (200 g), also known as ground blanched almonds, or sometimes referred to as fine almond flour.
- 1 cup fine defatted sesame flour (80 g) = 3/4 packed cup + 1 tbsp ground sesame seeds (113 g).
More Low-Carb Flour Conversions
- 1 cup regular almond flour (100 g) = 1/3 cup coconut flour (40 g) + 1 egg or egg white, plus 1-2 tbsp water if needed.
- 1 cup regular almond flour (100 g) = 1 cup ground sunflower seeds (100 g).
- 1 packed cup ground sesame seeds (113 g) = 1 packed cup flax meal (113 g).

Recipe Tips and Troubleshooting
Can I Use Carton Egg Whites?
Yes, you can! Carton egg whites work just as well as fresh ones. The recipe uses large egg whites, so for accuracy, count each egg white as 33 grams (1.2 oz). Make sure to weigh them using a kitchen scale for the best results.
Does This Keto Bread Taste Eggy?
Not at all! Even though this bread uses a lot of eggs, it doesn’t have an eggy flavor. The extra egg whites help make the bread fluffy, and just a few yolks are used to add structure. Plus, brushing one egg yolk on top of the loaf helps create a nice crust.
Can I Use Psyllium Husk Powder?
It's best to avoid ready-made psyllium husk powder. I've baked dozens of keto breads and I made all of them using whole psyllium husks that I powdered myself.
Pre-ground psyllium powder can make the bread too dense, flat, and even give it a purple hue with an unpleasant aftertaste. For the best results, buy whole psyllium husks and grind them yourself in a coffee grinder or food processor. This ensures you get the right texture and flavor in your bread.

Do I Need to Use Protein Powder?
We use protein powder to replace the gluten missing in low-carb bread. Whey or egg white protein isolate is ideal, but if you don't have it, the bread will still taste great, just less fluffy. Some keto recipes suggest xanthan gum for elasticity, but it can cause digestive issues for some people. If you'd like to use xanthan gum, replace the protein powder with 1 teaspoon of xanthan gum.
Is This Keto Bread Moist?
Compared to other low-carb breads, this keto yeast bread has minimal moisture, as long as you don't use any swaps and follow the recipe as it is. However, if you use ground sesame seeds instead of fine sesame flour, you may notice a bit more moisture. The psyllium and flax meal lock in moisture, which is essential for texture and flavor in keto baking.
If you prefer drier bread, you can dehydrate it in the oven after baking by placing the loaf directly on the rack at 212°F (100°C) for about 30 minutes. You can also toast the bread for a crispier texture.

Should I Weigh the Ingredients?
Yes! For the most accurate results, especially in low-carb baking, you should weigh the dry ingredients. While cup measurements are provided, they can vary. Weighing ingredients ensures consistency, which is important for achieving the best texture in the bread.
I'm Keto, Can I Really Use Sugar?
Yes! The sugar or yacon syrup you use to activate the yeast gets consumed during the fermentation process, leaving no carbs behind. If you don’t keep sugar at home, yacon syrup works just as well. You can also use other nutritive sweeteners like coconut sugar, maple syrup, or honey, but avoid non-nutritive sweeteners like erythritol or stevia, as they won’t activate the yeast.
How Much Will My Bread Rise?
The rise of your bread depends on several factors, such as the ingredients and process. A larger loaf pan or adding water too late in the process can result in a denser, flatter loaf. For best results, use a 5x8 inch loaf pan, but you can experiment with larger pans. Avoid silicone loaf pans as they may not be sturdy enough to hold the dough’s shape, leading to a denser, uneven loaf.
Why Is my Keto Bread Hollow Inside?
A hollow center is usually caused by uneven rising. If this happens, try making smaller, burger-sized buns instead of a full loaf. This will help the bread rise evenly and prevent air bubbles. You can also find more troubleshooting tips in the original keto bread guide.
Living at High Altitudes?
If you live at high altitudes, adjust your oven temperature by increasing it by 15-30°F. Start checking the bread after 45 minutes instead of 60, using a wooden skewer to test for doneness.
Storage Tips
After the bread has cooled, store it at room temperature for up to 3 days. Loosely cover it with a kitchen towel or parchment paper to avoid trapping moisture, which can make the bread soggy. Avoid airtight containers.
For longer storage, slice the bread and freeze it for up to 3 months. Place the slices in a freezer-safe bag or container, removing as much air as possible.
To reheat, toast slices in a toaster or toaster oven for a crispy texture. Alternatively, microwave a slice for 15-20 seconds for a softer result. If reheating a larger portion, bake in the oven at 350°F (175°C) for 10-15 minutes.

- 3 large egg yolks, divided
- 2 tbsp apple cider vinegar (30 ml)
Dry ingredients:
Instructions
- Prep: Before starting, read through the full recipe and check the blog post for tips, especially if you’re using any ingredient swaps.
- Activate the yeast: Turn on the oven light (just the light, not the heat). Pour 3/4 cup (180 ml) of warm water into a bowl. The water should be about 100°F (40°C) but not hotter than 110°F (45°C). If your oven doesn’t have a light option, preheat it to the lowest setting (around 120°F or 50°C), then let it cool for 30 seconds before proceeding.
- Add sweetener: Stir in yacon syrup or sugar until fully dissolved. Don’t worry, the sugar will be consumed during the fermentation process!
- Add the yeast: Sprinkle dry active yeast (or 30 g fresh yeast) into the water. Place the bowl inside the warm oven with just the light on, and let it proof for 10 minutes. The yeast should become frothy and increase in volume.
- Prepare the loaf pan: While the yeast is proofing, line a 5x8 inch (13x20 cm) loaf pan with parchment paper.
- Grind the psyllium husks: If using whole psyllium husks, grind them into powder using a coffee grinder or food processor. This ensures a better texture.
- Combine dry ingredients: In a large bowl, mix together the ground psyllium husk, defatted sesame flour, flax meal, coconut flour, whey (or egg white) protein powder, cream of tartar, baking soda, and salt. Use a hand mixer for an even consistency if needed.
- Mix the eggs: In another bowl, whisk 5 egg whites and 2 egg yolks. Reserve 1 egg yolk for brushing the top later.
- Combine wet ingredients: Add the egg mixture to the bowl with the proofed yeast. Add the apple cider vinegar and the remaining 1 1/4 cups (300 ml) of warm water.
- Mix the dough: Using a hand mixer or stand mixer, slowly add the dry ingredients to the wet mixture.
- Add about 1/2 cup at a time, mixing thoroughly after each addition.
- Form the dough: Once all the dry ingredients are mixed in, transfer the dough into the prepared loaf pan. Spread it evenly with a spatula, and if desired, score a line down the middle for a decorative slit effect.
- Proof the dough: Place the loaf in the oven with the light on for 60 minutes to allow it to rise. After proofing, remove the loaf and preheat the oven to 350°F (175°C) for fan-assisted or 380°F (195°C) for conventional ovens.
- Brush the loaf: Whisk the reserved egg yolk with 2 teaspoons of water and gently brush it on top of the loaf. Be careful not to press too hard and deflate the bread.
- Bake the bread: Optionally sprinkle sesame seeds on top, then bake for about 60 minutes. To prevent over-browning, cover the top with foil during the last 15-20 minutes if necessary.
- Cool the bread: Once baked, remove from the oven and let the bread cool in the pan. If you have another loaf pan, transfer the bread to it by lifting the parchment paper edges. This helps reduce moisture buildup.
- Slice and serve: Once the bread is completely cool, slice and serve. The recipe makes about 12-14 slices, depending on the loaf size.
- Storage tips: Store the bread at room temperature, loosely covered with a kitchen towel, for up to 3 days. To store longer, slice the loaf and freeze in batches of 2-4 slices for up to 3 months.
