Can You Really Make Pizza with Just Sourdough Discard?
Absolutely!
When poured into a screaming hot cast iron skillet, sourdough discard begins cooking immediately, creating a surprisingly sturdy crust. After a quick bake, it firms up enough to hold sauce, cheese, and toppings before finishing on a hot pizza stone.
The result is somewhere between a traditional pizza crust and a crispy flatbread—with all the incredible flavor that naturally fermented sourdough provides.
Ingredients
For the Crust
- 1 cup sourdough discard (fed or unfed)
For the Toppings
- Pizza sauce
- Shredded mozzarella cheese
- Pepperoni, sausage, vegetables, basil, or your favorite toppings
- Optional drizzle of olive oil
Equipment You'll Need
- 10–12 inch cast iron skillet

How to Make Sourdough Discard Skillet Pizza
Step 1: Preheat Your Oven
Place your pizza stone inside the oven and preheat to 425°F.
At the same time, place your cast iron skillet in the oven so it becomes extremely hot.
A properly heated skillet is the secret to creating a crispy crust.
Step 2: Pour in the Sourdough Discard
Carefully remove the hot skillet using oven mitts.
If desired, lightly drizzle the skillet with olive oil.
Pour 1 cup of sourdough discard directly into the center of the hot pan.
Tilt the skillet gently until the discard spreads into an even circle.
Return the skillet to the oven.
Step 3: Bake the Crust
Bake for 7 minutes.
The crust should begin to set, bubble slightly, and develop a light golden color around the edges.
Step 4: Add Your Favorite Toppings
Remove the skillet from the oven.
Spread on your pizza sauce.
Add mozzarella cheese and your favorite toppings.
Keep toppings fairly light so the crust stays crisp.
Step 5: Finish on the Pizza Stone
Using a pizza peel or large spatula, carefully slide the pizza from the cast iron skillet onto the preheated pizza stone.
Bake for another 7 minutes, or until:
- The cheese is melted and bubbly
- The crust is golden brown
- The bottom is crisp
- The edges are lightly browned
Remove from the oven, allow it to cool for a minute or two, then slice and enjoy.

This recipe skips all of that.

Starting the pizza in a cast iron skillet helps set the base quickly, while transferring it to a pizza stone finishes the bake and creates a crisp, evenly cooked crust.
It's a simple technique that delivers impressive results with very little effort.
