The tradition of pan-style pizza finds its roots in the American mid-west, where the goal was always a thick, fried-bottom crust that could hold a mountain of toppings. While the classic versions relied on long fermentation, the use of a cast iron sourdough discard pizza blends this hearty history with the ancient art of wild yeast.
Sourdough discard is essentially a living culture that has lost its peak lifting power, but it retains a complex, tangy acidity that commercial yeast simply cannot replicate. By utilizing the conductive heat of cast iron, the dough undergoes a rapid transformation, mimicking the effect of a professional pizza oven.
This method honors the principle of "waste not, want not," a philosophy passed down through generations of home cooks. The result is a marriage of cultural convenience and artisanal flavor, where a humble skillet creates a crust that is both sophisticated in taste and comforting in texture.
Why You'll Love It
-
- Honestly, it is just such a relief to use up those 2 cups sourdough discard without waiting hours for a rise; it's like magic in a pan.
-
- That cast iron skillet does all the heavy lifting, giving you a crust that's wonderfully crispy on the edges but still has a cozy, soft center.
-
- I mean, the smell of 1 teaspoon Italian seasoning and 1 teaspoon granulated garlic hitting a hot pan... wow, it just makes the whole house feel like a home.
-
- It's a quick little win for a busy night, yet it tastes so complex, almost like something from a fancy bakery but way more comforting.
"Honestly, I can't believe how fast this is. That crispy edge is just... wow. My kids actually asked for seconds!"
Essential Ingredient Guide
- 2 cups sourdough discard: This is the heart of the recipe. Use what you've got in the fridge; if it's a bit too thick, just stir in a tiny bit of warm water to make it easier to spread.
- 1 cup shredded mozzarella cheese: I always prefer the good melty kind. It creates that beautiful, stretchy blanket of gold that we all crave on a Friday night.
- 1/4 cup thinly sliced fresh mozzarella (optional): Well, this is just a little extra touch. Those little pools of white cheese add a creamy, fresh contrast to the shredded kind.
- 1 teaspoon Italian seasoning, dried: These herbs bring in those earthy, nostalgic notes. I love how they toast slightly in the dough before the sauce even goes on.
- 1/8 teaspoon baking soda (pinch): Don't let the small amount fool you. This little pinch helps the crust lift and brown just right since we aren't proofing the dough.
- 1 tablespoon olive oil: This is what gives us that gorgeous, fried-bottom crunch. Make sure to coat the hot skillet well so nothing sticks.
Complete Cooking Process
-
Getting Everything Ready:
I start by getting that 10" cast iron skillet hot in the oven first. While that's heating, I just whisk together the sourdough discard and seasonings in a simple bowl.
-
Building the Flavor:
The flavor really starts to bloom when the seasoned dough hits the oiled, hot pan. Those 10 minutes of initial baking let the garlic and herbs wake up.
-
Managing the Crunch:
The secret is that two-step bake. Baking the crust first ensures the center doesn't get soggy once you add the 1/2 cup pizza sauce and cheese.
-
The Final Melt:
Once the toppings are on, a quick 5-6 minutes finishes it off. I look for the cheese to be bubbly and those edges to be a deep, golden brown.
-
The Patient Pause:
I've learned the hard way—let it rest for 2 minutes. It lets the cheese set so your slices stay neat instead of sliding all over the place.
-
Preheat the skillet in the oven; a hot pan gives the crust its signature crunch.
-
Forget about proofing: the discard’s natural leavening is enough.
-
If the discard is too thick, add a tablespoon of warm water to thin it out.
-
Keep toppings to a moderate amount so the crust doesn't get soggy.
Pro Tips
Just trust your instincts and enjoy the process!
Better For You Treats
It's a lovely way to reduce waste by using your sourdough discard. Plus, by making it at home, you control the salt and avoid all those strange preservatives found in store-bought crusts.
Ways to Make it Your Own
I sometimes make a Basil-Garlic version with fresh basil and red pepper flakes. Or, if you're feeling healthy, try roasting some zucchini and bell peppers to pile on top of the cheese.
Serving Suggestions
I love serving this right in the skillet for a rustic feel. Pair it with a fresh arugula salad with lemon vinaigrette to cut through the richness of the 1 cup shredded mozzarella cheese.
Frequently Asked Questions
→ Do I really not need to let the dough rise?
Nope, honestly you don't! The sourdough discard and that pinch of baking soda do all the work for you in the oven.
→ Can I use a different pan if I don't have cast iron?
You can, but look, you'll miss out on that specific deep-dish crunch. A heavy oven-safe cake pan is your next best bet.
→ What if my crust is still a bit gooey in the middle?
Oops, that usually happens if there are too many toppings. Just pop it back in for a few more minutes until it feels firm to the touch.

Recipe Details
Ingredients
Crust
-
01
2 cups sourdough discard
-
02
1/2 teaspoon salt
-
03
1 teaspoon Italian seasoning, dried
-
04
1 teaspoon granulated garlic
-
05
1/8 teaspoon baking soda (pinch)
-
06
1 tablespoon olive oil, plus more for coating the skillet
Toppings
-
01
1/2 cup pizza sauce (homemade or store-bought)
-
02
1 cup shredded mozzarella cheese
-
03
1/4 cup thinly sliced fresh mozzarella (optional)
-
04
1/4 cup sliced pepperoni or any topping of choice
Instructions
First things first, let's get that oven warming up to 450°F (232°C). Go ahead and tuck your 10" cast iron skillet right inside while it preheats; honestly, getting that pan thoroughly hot is the real secret to that lovely crispy crust we're after.
While the oven is doing its thing, grab a bowl and stir together your sourdough discard, salt, Italian seasoning, granulated garlic, and that little pinch of baking soda. Just mix it until everything is well combined.
Now, be careful here—take the hot skillet out and brush a light coating of olive oil over the surface. Spoon your dough mixture right in and use a spatula to gently spread it all the way to the edges. It's a bit like painting, really.
Slide it back into the oven, uncovered, for about 10 minutes. You'll know it's doing well when the edges start turning golden brown and a light, cozy steam fills the oven.
Carefully pull the skillet out again. Now we add the flavor—spread your pizza sauce over that partially cooked crust. I usually leave a tiny border on the edge, but it's up to you.
Sprinkle on your shredded mozzarella and those fresh mozzarella slices, then scatter your pepperoni or whatever toppings you've picked out.
Return the skillet to the heat for another 5–6 minutes. We're looking for the cheese to be all bubbly and golden, and the crust to have a nice, firm bite.
Take it out and just let it rest in the pan for about 2 minutes. I've learned the hard way that this lets the cheese set just enough to make slicing so much easier.
Use your pizza cutter or a sharp chef's knife to slice it up. I love serving it right out of the skillet—it just feels more rustic and warm.
Well, look at that. Enjoy a slice that tastes like a classic pan pizza but has that wonderful, complex sourdough tang.

This exceeded my expectations. I really liked how the 2 cups sourdough discard and 1/2 teaspoon salt came together. My kids even asked for seconds.
Nice base recipe. The discard flavor was nice, but i would reduce the salt a little. I might try it again with some adjustments.
I wanted to love this dish, but it didn't quite work for me. It took slightly longer than the recipe said. I think with some tweaks it could be really good.
