Sunflower Seed Flour Keto Bread – Simple, Nutty, and Satisfying
This sunflower seed flour keto bread brings real bread vibes without the carbs. It slices well, toasts beautifully, and has a mild, nutty flavor that works with both sweet and savory toppings. If almond flour isn’t your thing or you’re avoiding nuts, sunflower seed flour is a fantastic swap.
The texture is soft yet sturdy, and it doesn’t feel eggy. Add a pat of butter, a fried egg, or avocado, and you’ve got a quick, filling meal.
What Makes This Recipe So Good

What You’ll Need
- Sunflower seed flour: Finely ground, defatted if available for best texture. You can grind hulled sunflower seeds in a blender if needed.
- Coconut flour: A small amount adds structure and absorbs moisture.
- Psyllium husk powder: For chew and bread-like structure.
Use a fine powder.
- Baking powder: Aluminum-free for a clean taste.
- Apple cider vinegar: Reacts with baking powder for lift.
- Eggs: Room temperature, large.
- Egg whites (optional but helpful): For extra rise and a lighter crumb.
- Unsweetened almond milk or water: To hydrate the psyllium and flours.
- Olive oil or melted butter: Adds moisture and richness.
- Salt: Fine sea salt or kosher salt.
- Optional add-ins: Sesame seeds, sunflower seeds, chia, garlic powder, onion powder, dried herbs.
How to Make It

- Prep the pan and oven: Preheat oven to 350°F (175°C). Line a 8.5 x 4.5-inch loaf pan with parchment, leaving overhang for easy lifting. Lightly grease the sides.
- Whisk dry ingredients: In a mixing bowl, combine 1 3/4 cups sunflower seed flour, 2 tablespoons coconut flour, 2 tablespoons psyllium husk powder, 2 teaspoons baking powder, and 1/2 teaspoon salt.
Whisk to break up any clumps.
- Blend the wet ingredients: In another bowl, whisk 4 large eggs, 2 additional egg whites (about 1/4 cup), 3 tablespoons olive oil or melted butter, 1 teaspoon apple cider vinegar, and 3/4 cup unsweetened almond milk or water until smooth.
- Combine: Pour the wet mixture into the dry. Stir with a spatula until a thick, scoopable batter forms. It will look a bit dense at first—give it 1–2 minutes to hydrate as psyllium thickens.
- Adjust if needed: If the batter is crumbly, add 1–2 tablespoons more liquid.
If it’s loose, sprinkle in 1 teaspoon extra coconut flour and stir.
- Fill the pan: Scrape batter into the prepared pan. Smooth the top with a damp spatula. For a bakery look, score a shallow line down the center with a butter knife.
Sprinkle seeds on top if you like.
- Bake: Bake for 40–50 minutes, until the top is firm and golden and a toothpick comes out clean from the center. The loaf should feel set and spring back lightly.
- Cool properly: Let the bread rest in the pan for 10 minutes. Use the parchment to lift it out and cool on a rack for at least 1 hour before slicing.
This step sets the crumb.
- Slice and serve: Use a serrated knife for even slices, about 1/2-inch thick. Toast for best flavor.
Storage Instructions
- Room temperature: Keep in an airtight container for 24 hours if your kitchen is cool and dry.
- Refrigerator: Store slices in a sealed container for up to 5 days. Place parchment between slices to prevent sticking.
- Freezer: Freeze sliced bread in a zipper bag for up to 2 months.
Toast straight from frozen or thaw in the fridge.
- Reheat: Best warmed in a toaster or skillet with a little butter or oil to revive the crust.

Health Benefits
- Low in carbs: Fits keto and low-carb plans while satisfying bread cravings.
- Rich in healthy fats: Sunflower seeds provide unsaturated fats that support heart health.
- Good source of fiber: Psyllium and seeds promote digestion and fullness.
- Micronutrients: Sunflower seeds bring vitamin E, magnesium, and selenium.
- Gluten-free and nut-free: A great option for those avoiding gluten and tree nuts.
Pitfalls to Watch Out For
- Green crumb: Sunflower seeds can turn green when they react with baking powder. It’s harmless. Add 1–2 teaspoons lemon juice or reduce baking powder slightly if you want to avoid it.
- Overbaking: Too long in the oven makes it dry.
Start checking at 40 minutes.
- Skipping the cool-down: Slicing while hot leads to a gummy crumb. Let it set for at least 1 hour.
- Wrong psyllium: Coarse psyllium can make the bread purple or rubbery. Use a fine powder and measure carefully.
- Too much moisture: If your sunflower flour is coarse, it won’t absorb as much.
Adjust with a pinch more coconut flour.
Recipe Variations
- Everything loaf: Mix 1 tablespoon everything bagel seasoning into the batter and sprinkle more on top.
- Herb and garlic: Add 1 teaspoon garlic powder and 1–2 teaspoons dried herbs like rosemary, thyme, or Italian seasoning.
- Seeded crunch: Fold in 2 tablespoons sunflower seeds, 1 tablespoon sesame seeds, and 1 tablespoon chia for texture.
- Olive and rosemary: Stir in 1/3 cup chopped pitted olives and 2 teaspoons chopped fresh rosemary. Reduce liquid by 1 tablespoon to balance.
- Cinnamon “toast” version: Add 1 teaspoon cinnamon and 1 teaspoon vanilla. Great for breakfast with butter.
FAQ
Can I use almond flour instead of sunflower seed flour?
Yes, you can swap by weight in many recipes.
Here, use 1 3/4 cups finely ground almond flour in place of sunflower seed flour and keep everything else the same. The flavor will be slightly sweeter and the crumb a touch softer.
What if I don’t have psyllium husk powder?
Psyllium is key for structure. You can try 1 tablespoon ground flaxseed plus 1 tablespoon chia seed as a backup, but the texture will be more crumbly and less bread-like.
Why did my bread turn green?
Sunflower seeds react with alkaline ingredients, especially baking powder, producing a harmless green tint.
Add lemon juice or vinegar, or use a bit less baking powder next time. The taste and safety are unaffected.
Can I make this dairy-free?
Yes. Use olive oil or avocado oil instead of butter, and choose water or unsweetened non-dairy milk.
The bread will still be moist and flavorful.
How do I prevent a dense loaf?
Use room-temperature eggs, fine psyllium powder, and don’t overmix. Make sure your baking powder is fresh and preheat the oven fully. Letting the batter rest a minute before baking helps, too.
What size pan works best?
An 8.5 x 4.5-inch loaf pan gives the best height.
A 9 x 5-inch pan works but yields a slightly shorter loaf. Mini loaf pans also work—start checking around 22–25 minutes.
Can I make rolls instead of a loaf?
Yes. Scoop the batter into 6–8 mounds on a parchment-lined sheet, smooth tops with damp fingers, and bake at 350°F (175°C) for 20–25 minutes until set and lightly golden.
Is this bread good for toasting and sandwiches?
Absolutely.
It toasts well and holds together for grilled cheese, BLTs, breakfast sandwiches, and more. Slice slightly thicker for sandwiches.
