How to make Keto Sub Rolls
  1. Preheat your oven to 175C/350F. Line a cookie sheet with parchment paper and set aside.
  2. In a mixing bowl, add the dry ingredients and mix well. Set aside.
  3. Add the egg whites to a large mixing bowl and beat with your hand mixer until foamy.
  4. Add the vinegar and water and continue mixing.
  5. While continuously mixing, pour ½ a cup of the dry ingredients into the bowl, followed by the rest.
  6. Stop the mixer as soon as it comes together and give a quick stir with a spatula.
  7. Leave to sit for about 5 minutes so that the dry ingredients can soak up the liquids.
  8. Once the dough feels firmer and sticky, spoon out onto a piece of parchment and shape into a thick rectangle.
  9. Cut into 4 evenly sized rectangles and place onto your prepared cookie sheet.
  10. Gently round the edges and cut 3 deep slices in the tops of each bun.
  11. Bake for 20-25 minutes until the buns are golden brown and sound hollow when tapped on the base.
  12. Leave to cool completely before slicing (if sliced hot they will deflate).

  1. Mine deflated even after letting them cool, not sure where I went wrong… anyways they were tasty flat buns.

  2. Looking forward to trying this out – first attempt at keto hot dog buns was another recipe that is similar that had a lot of mozzarella…it turned out OK, but not fluffy. Any advice on adding a little yeast to your recipe?

    • Hi Ryan,

      These buns are quite fluffy as they are. If you want to add yeast for the flavor I would start with 1 tsp dry yeast with 1 tsp inulin (to feed the yeast) and activate it in 1/4 cup of the water, warmed.

      I’d love to hear how they turn out!

  3. OMG! This is my first time EVER leaving a review but I just must! I have spent soooo much time looking for a keto bun recipe that wasn’t eggy or cheesy and THIS IS IT! I followed directions exactly and used my silicone hoagie bun molds and had pulled pork buns last night which were amazing. No one believed me when I told them they were keto! As I write this I’m using my hamburger bun molds and seeing how they turn out. THANK YOU so much for this recipe! My summer of bbq’ing is saved!

      • Hey again Gerri, I wanted to see how your recipe would work as a pizza crust and it was incredible. Once I made the dough, I split it in half and it was enough for two pizzas. I pre-cooked the dough for 15 minutes and then once cooled added the toppings and then on my pellet grill at 450 for 30 minutes. Incredible. I just wish I knew how to post pictures

  4. Hey! I am new to keto and have a couple questions. This bread sounds too good to be true haha – Are all carbs valued the same? So for example, if I stay under 20 net each day does it matter where they come from? Should something like this bread be considered a treat? Or just counted in your daily intake?
    Thanks!! 🙂

    • Hi Kat,

      This bread can be counted in your daily intake. Some people choose to “spend” their carb allowance on keto-friendly breads and treats, and others on just veggies – it’s all up to you 🙂
