The art of utilizing sourdough discard is rooted in a timeless culinary philosophy of waste-not, want-not. For generations, bakers in European villages viewed the leftover starter not as a byproduct, but as a precious catalyst for flavor, using it to enrich pancakes, crackers, and rustic flatbreads. This tradition reflects a deep respect for the fermentation process and the living cultures that give bread its characteristic depth.
When combined with the heavy-duty heat of a cast iron skillet, this traditional cast iron sourdough discard pizza takes on a modern, fast-paced twist. The skillet mimics the intense, dry heat of a professional stone oven, allowing the sugars in the 1 tsp brown sugar and the natural starches in the dough to caramelize quickly. This creates a blistered texture that is rare in home-cooked pizzas.
Culturally, the addition of 2 Tbsp crushed tomatoes and a pinch smoked paprika nods to the Mediterranean influence that defined early pizza styles. By melding these old-world fermentation techniques with the rustic reliability of cast iron, the dish becomes a bridge between slow-living traditions and the needs of a contemporary kitchen.

Essential Ingredient Guide
- 1 cup sourdough discard: This is the heart of the crust, giving it that gentle tang. Just stir it in well; no need for any fancy kneading, it's quite forgiving.
- 1 cup shredded mozzarella cheese: I prefer a good melt that stretches just right. Sprinkle it on carefully so it blooms without covering every single bit of that beautiful sauce.
- a splash of balsamic glaze: Now, this is optional, but it adds a lovely, sweet-tart finish. A little drizzle at the end really makes the colors pop on the plate.
- Pinch smoked paprika: Just a tiny bit adds a whisper of wood-fired flavor. It's a small touch, but wow, it really deepens the overall taste.
- 2 Tbsp extra‑virgin olive oil: I use this both in the dough and for the pan. It's what gives us that golden, crispy bottom we're all after.
- 1 tsp brown sugar: A touch of sweetness helps the crust brown beautifully. It balances the acidity of the sourdough just right, I think.
Complete Cooking Process
-
Getting Ready:
Start by gathering your 1 cup sourdough discard and warm water. Stirring everything together until a sticky dough forms is a quiet, simple start to the meal.
-
Building the Base:
Letting the dough rest for 5 minutes is key; it just relaxes and becomes so much easier to spread. Then, that hot skillet creates those wonderful, darkened blisters.
-
Perfecting the Crunch:
The flip is the magic moment. Once the underside is golden, you've locked in that structure, ensuring it stays crisp even under the toppings.
-
Melting it All Together:
Covering the pan for a few minutes lets the 1 cup shredded mozzarella cheese bloom. It turns the tomato sauce into a glossy, rich glaze that feels just right.
-
The Final Rest:
I always let it sit on the board for 2 minutes. It just lets the crust set so you get a clean, satisfying bite when you slice into those wedges.
-
Preheat your skillet until a drop of water sizzles and evaporates instantly for those signature blistered edges.
-
Use a lightly oiled piece of parchment to transfer the dough safely into the hot pan.
-
Don't overload your toppings; stick to the sauce, cheese, and basil to avoid a soggy crust.
-
Close the skillet with a lid or baking sheet to help the cheese melt perfectly while the bottom crisps.
Pro Tips
Just take your time and enjoy the process, you've got this!
Better For You Treats
I love that we're using natural sourdough fermentation here. It's a bit kinder to the gut and keeps the glycemic load lower, so you can feel good about that slice.
Ways to Make it Your Own
You could try replacing the tomato sauce with a basil pesto and adding pine nuts. Or, if you're feeling bold, top it with rotisserie chicken in hot sauce and pecorino cheese.
Serving Suggestions
A crisp arugula salad with lemon vinaigrette is just lovely on the side. For a little extra fancy, add some fresh cherry tomatoes and a drizzle of balsamic glaze.
Frequently Asked Questions
→ Can I use a different pan if I don't have cast iron?
Well, you can, but honestly, the cast iron is what gives it that specific, crispy crust. A heavy stainless steel pan is your next best bet.
→ What if my dough is too sticky to handle?
Oops, that's just the nature of discard dough! That's why I suggest using the parchment paper method—it keeps things clean and easy.
→ Do I really need to let the dough rest?
Yeah, just for 5 minutes. It makes a world of difference in how easily the dough spreads into the skillet.

Instructions
In a medium bowl, go ahead and combine your 1 cup sourdough discard, 3/4 cup warm water, 2 Tbsp extra-virgin olive oil, 1 tsp sea salt, 1 tsp brown sugar, and 1 tsp baking powder. Just stir it all together until a sticky dough forms. Honestly, a well-mixed discard dough softens up so quickly—no kneading needed here.
Cover your bowl loosely with a bit of plastic wrap and let that dough just rest for 5 minutes. While you wait, it'll rise just a tiny bit and become so much easier to spread.
Place your 12-inch cast iron skillet on the stovetop and preheat it to medium-high, which is about 400°F. Well, just let it heat up until a drop of water sizzles and evaporates within a second.
Now, look, the real keystone to a crisp crust is to lay the dough on a lightly oiled piece of parchment and then transfer it carefully to the hot skillet. Use your spatula to press the dough into the skillet, making sure it snugly covers the 12-inch surface without any bubbling.
Cook the first side for 5-6 minutes. You should see those lovely edges start to blister and darken. Flip the entire crust once the underside is golden and the dough doesn't feel tacky anymore.
While you're flipping, whisk together your 2 Tbsp crushed tomatoes, 1 clove garlic, minced, 1/2 tsp dried oregano, and a splash of olive oil in a small saucepan. Warm that sauce for about 2 minutes, then spread a thin, even layer over the flipped crust.
Immediately sprinkle on the 1 cup shredded mozzarella cheese, a handful fresh basil leaves, and a pinch smoked paprika over the sauce. The cheese should start to melt, but not fully—that's okay, it lets the next step lock in all that flavor.
Close the skillet with its lid or a large metal baking sheet and lower the heat to medium. Cover it for 3-4 minutes; the cheese will bloom, the crust will crisp up, and the tomato sauce will meld into a glossy glaze.
Remove the skillet from the heat and let the pizza rest on a cutting board for 2 minutes. This just lets the crust's bite set before you carefully slice it into wedges with a pizza cutter or sharp knife.
Plate your slices with a light drizzle of extra-virgin olive oil or balsamic glaze. Serve it immediately while the crust is still blistered and that cheese is bubbling. Wow, it's just wonderful.
