Gluten-Free Sourdough Waffles

I previously described how I maintain my sourdough starter at 60g in the fridge, feeding it weekly. Since sourdough can basically triple itself in 24 hrs (or in a week in my case, since I keep it in the fridge), I need to discard 2/3rd of it each time so it maintains the same size. I also keep the discard in the fridge, in a separate jar, and it builds up at a rate of about 30g per week (with another 10g lost down the sink). What do I do with this? A popular option is to turn it into waffles!

I received a Breville “the No Mess Waffle” maker appliance as a present a few years back, before I went gluten-free, and made lots of different types of waffles. I can confidently say that this recipe makes the best plain waffle that I’ve had from the waffle maker. It has a good crispy texture and a great taste that works as a vehicle for a range of sweet toppings.

My discard jar holds about 180g of discard, so it takes around 6 weeks to fill up and that’s probably about as frequent as we’d want to make waffles. The recipe below is heavily based on this sourdough waffle recipe from Cultures for Health. Note – it does need to be started the evening before, for cooking into waffles for breakfast the following morning.


  • 180g of discarded sourdough starter, from the fridge
  • 140mL of water (no warmer than lukewarm)
  • 90g white rice flour
  • 45g sticky rice flour (a.k.a. glutinous rice flour or sweet rice flour)
  • 45g cornflour
  • 1/4 teaspoon (heaped) baking powder
  • 1/2 teaspoon table salt
  • 1 tablespoon (20mL) maple syrup
  • 2 teaspoons (10mL) vanilla extract
  • 2 eggs
  • 30g unsalted butter, melted
  • 1/2 teaspoon bicarb soda
  • 1 teaspoon (5mL) water – optional


  1. In a sealable bowl or container, mix the discard with the water, then mix in the flours. Seal and leave on the bench overnight.
  2. In the morning, when the discard has reactivated and turned the flour mixture bubbly, put the mixture in a large bowl, and add in the remaining ingredients (excepting the bicarb soda). Stir with a fork until there are no big lumps.
  3. If the bicarb soda is very powdery, it can be evenly sprinkled over the top. If it’s a bit lumpy, dissolve it in a teaspoon of water, then tip into the mixture. Quickly stir through and leave until ready to start cooking.
  4. Set the waffle maker to 5 (or desired crispness/brownness), and when ready, pour 1/2 cup (125mL) of mixture evenly across the cooking surface. Keep cooking each waffle this way until done.

Makes 6 waffles. Serve with maple syrup, sliced fruit, berries, cream/yoghurt, or however you like them!

Surplus waffles can be frozen, separated with baking paper. They reheat well split in half and popped in the toaster!
