Sourdough discard pizza on a cast iron

Easy Sourdough Discard Pizza (20-Minute Family Meal)

If you're anything like me, there's a jar of sourdough discard sitting in your fridge right now, waiting for you to do something with it. This is my lazy-girl (aka stay-at-home mom with no time) way to use it up. No dough to knead, no rise time, no measuring. Just pour, top, and bake. It's on our table about once a week and it's a total family favorite.


What you'll need

  • Sourdough discard (straight from the fridge is fine)
  • A drizzle of oil for the pan
  • Italian seasoning, or whatever dried herbs you have on hand
  • Pizza or pasta sauce
  • Shredded mozzarella
  • Your favorite toppings (we love cooked ground beef and sliced mushrooms)
  • A cast iron skillet or any oven-safe pan, any size


How to make it

  1. Heat your pan. Preheat the oven to 425°F. Add a drizzle of oil to your cast iron and get it hot, either on the stovetop or in the oven while it preheats.
  2. Pour in the discard. No measuring here, I just eyeball it. Pour in enough discard to cover the bottom of the pan, then spread it so it comes up the sides a little. That edge becomes your crust and holds all the toppings in.
  3. Season it. Sprinkle Italian seasoning over the top. A little extra drizzle of oil is nice here too.
  4. Bake the crust. Bake for 10 minutes. This is when I chop the veggies and get the toppings ready.
  5. Add your toppings. Spread on the sauce, add the cheese, then pile on whatever toppings you want. Finish with a little more cheese.
  6. Bake again. Back in the oven for about 10 more minutes, depending on how melty (or a little burnt) you like your cheese.
  7. Slice and serve. Let it sit for a minute, then slice it right on a cutting board.


A few notes

  • Pan size doesn't matter. Use whatever cast iron or oven-safe pan you have. A bigger pan gives you a thinner crust, a smaller one gives you a thicker one.
  • Use what's in your fridge. This is a clean-out-the-fridge kind of dinner. Leftover veggies, meat, whatever cheese you have, it all works.
  • Start to finish, about 20 minutes. Perfect for those nights when you're running low on time with a hungry little one.
