Can I use active sourdough starter instead of discard?
Yes, but for best results, use unfed (inactive) sourdough discard. Active starter can cause the bake to puff up more and change the texture.
Is this recipe gluten-free?
Only if you use a gluten-free sourdough starter. Otherwise, standard sourdough discard will contain gluten.
Can I make it dairy-free?
Absolutely! Substitute the cheese with a dairy-free alternative and use a plant-based milk like almond or oat milk.
How do I store leftovers?
Store in an airtight container in the fridge for up to 4 days. Reheat in the oven or microwave until warmed through.
Final Thoughts
From waste to wow, this sourdough breakfast bake proves that discard can be delicious. It’s hearty, customizable, and perfect for feeding your family or impressing brunch guests. With its warm, tangy flavor and cheesy comfort, it just might become your new favorite way to start the day.
