Instructions

  • In a large bowl, mix sourdough discard, flour, warm water, salt, sugar, and instant yeast until a sticky, lumpy dough forms.
  • Cover bowl and let dough rise at room temperature for 2 hours.
  • While dough is resting, heat 1 tablespoon olive oil in skillet and cook onions over medium heat for 15–20 minutes until caramelized.
  • Preheat oven to 425°F. Grease a baking pan with 1 tablespoon olive oil. Press rested dough flat into pan and dimple the surface with your fingers.
  • Drizzle remaining 1 tablespoon olive oil and spread caramelized onions across the top.
  • Bake in oven for 25–30 minutes or until crust is golden brown.
  • Remove from oven and let cool slightly before slicing and serving.
  • Store leftovers wrapped at room temperature for short term or freeze for later enjoyment.

Notes

Swap instant yeast for a full sourdough process by extending the rise time to 4–6 hours. You can substitute frozen caramelized onions for quick prep. Cast iron skillets can be used in place of a baking pan for crispier results.
