How To Make Gluten Free Keto Sub Sandwich Bread

Sandwiches are a food we all love. From lunch to dinner to snacks sandwiches are amazing. Sandwich bread that is low carb, gluten free and keto friendly can be really hard to find and when you do find it the bread is usually flat and dense.

This recipe is amazing! It’s easy, quick, and nice and fluffy just like traditional sub sandwich bread.

Secret To Fluffy Bread Without Yeast

My favorite thing about this recipe is that it does not require yeast which makes this recipe extremely quick.

Now you may ask how can bread be fluffy without yeast. The answer tot that is baking powder and cider vinegar.

Remember the old vinegar and baking soda volcano? That foamy bubbly reaction is caused by the combination of the acid in the vinegar and the gases in the baking soda. When they come in contact with the oxygen in the air they create an expanding explosion so to speak. As a result when you combine vinegar and baking powder in your baked good that expanding explosion is happening in your baked good which results in a light fluffy baked good

Always Use Double Acting Baking Powder

When using baking powder and vinegar as a rising agent always use double acting baking powder.

Double acting baking powder expands twice. Once while it is being mixed into the other ingredients and again as it is being baked. As a result your baked good while rise faster an higher than baking soda or single acting baking powder.

How To Keep The “Sub” Shape

When making sub sandwich bread without yeast the dough is going to need some help to keep it’s shape. Without yeast the dough will be slightly thinner and limp. Therefore to help keep the shape a holder must be used.

If you have a hot dog bun mold these work perfect however if you do not have one you can easily make one using foil.

How To Make Foil Holders

To make the holders all that’s needed is 5-7 strip of foil measuring 12 x 4 inches. Fold each strip in half making them 6 x 4 inches. Folding the strips in have is very important. The double layer is needed for stability. The foil also helps so the rolls do not brown as fast.

Next, roll each foil strip one at a time around a rolling pin to create a “cradle” to put the dough in.

Why Sour Cream

This recipe calls for sour cream which may seem a little strange. The sour cream gives moisture and texture to the dough for this reason it can not be substituted with milk of any kind.

Psyllium Husk Powder

Psyllium husk powder is another ingredient that is vital to the texture of this recipe.

The psyllium husk powder is the binding agent that “glues” the ingredients together. Without the psyllium husk powder there is no binding agent and as a result the ingredients will fall apart after they are baked.

Also make sure psyllium powder is used and not the whole psyllium husk. The fine texture of psyllium husk powder is needed for that smooth fluffy texture in the roll.


For “Gluten Free Keto Sub Sandwich Bread” all that’s needed is almond flour, coconut flour, psyllium husk powder, ground flax seeds, baking powder salt, sour cream, eggs, oil, seasoned salt and seasoned pepper.

To Make this bread just whisk together all the dry ingredients. Add the wet ingredients. Beat the ingredients all together. Place the dough into the holders. Bake the rolls and serve them however you choose.

Using The Foil Holders

Lightly spray each foil holder with cooking spray to prevent the dough from sticking. Scoop about 4-5 tablespoons of the dough into the center of each holder. Make sure the holders are mostly full and have space at the top and the bottom so the rolls can expand. Place the holders onto a large baking sheet and bake.

  • The only Psyllium Husk Powder I can readily find is at a local co-op and it’s labeled Premium Dietary Fiber Supplement . It’s in a large 12 oz bottle. Doesn’t necessarily say on the front label for baking, but it is a powder. Is this how it’s typically sold?? Thanks! Hopefully, you can get right back to me!! Sylvia

    • I buy mine in bulk in the whole foods section in my local grocery store but yes it is many times labeled as a dietary fiber.

  • 1 star
    The subs never turned out like picture. Adding up the calories and such make this a very high caloried sun bun.

  • Can i freeze these rolls? Baked or unbaked bette to freeze? And i havent got double acting baking there a substitute?

    • Yes, you can freeze these rolls. It is best to freeze them after they are baked and cooled, gluten free dough tend to dry out if it is not baked. If you do not have double acting baking powder, you can use baking soda just reduce the amount by 1 tsp
