FAQ on Easy Sourdough Discard Pizza in Cast Iron
How do I make the pizza crust crispy?
To achieve a crispy sourdough pizza crust, preheat your cast iron skillet in the oven before adding the dough. The high heat of the skillet will give the crust that desired golden brown texture.
Can I use an active starter instead of sourdough discard?
Yes, you can use a fed sourdough starter instead of discard. The flavor will be more tangy, and the texture might be slightly different, but it will still be delicious.
What if I don’t have a cast iron skillet?
If you don’t have a cast iron skillet, you can use a pizza stone or a baking sheet. However, the results may not be as crispy as with a Lodge cast iron skillet.
How long should I bake the pizza?
Bake the pizza at 425 degrees Fahrenheit on the middle rack for 10-15 minutes or until the cheese starts to turn golden brown. For an even crispier crust, you can bake it for an additional 2-3 minutes.
Can I make the pizza dough ahead of time?
Yes, you can prepare the dough the night before and store it in an airtight container in the fridge. Allow it to come to room temperature the next morning before baking for best results.
