You ever wind up with a sad cup of sourdough discard sitting in your fridge, and wonder what to do with it (besides feeling guilty)? You’re not alone. Last week, I was staring at my ever-growing jar and, honest to goodness, couldn’t face one more batch of pancakes. So, I did some kitchen wizardry between dog walks and making endless cups of tea, and hey, I landed on these Sourdough Discard Pizza Crackers. Now they’re my go-to when I need a salty snack and don’t want to toss perfectly good starter. My kid even calls them the “snack with the pizza crunch”—which I can’t decide if it’s cute or just makes me sound old. Oh, and if you’re a fan of crispy edges (who isn’t?), this is your jam.
Why You’ll Keep Making These (Like I Do…)
I grab this recipe whenever the snack cravings hit, especially on those “I don’t really want to cook but something with cheese sounds good” evenings. My family attacks the whole tray if I leave them unattended (I learned my lesson—hide a handful for yourself!). They’ve got that pizzaria smell, but none of the grease. Plus, no waiting for dough to rise, which is a blessing when you’re tired and the dog keeps begging to be let out. And I’ve messed up the seasoning before and guess what? Still delicious. They’re incredibly forgiving.
Your Must-Haves (and Sub-ins)
- 1 cup (about 250g) sourdough starter discard (unfed, straight form the fridge is cool)
- 2 tablespoons olive oil (I’ve used melted butter in a pinch—tastes richer)
- ⅓ cup finely grated parmesan (my grandmother swore by Pecorino, but honestly, it’s whatever hard cheese you have)
- ½ teaspoon Italian seasoning (sometimes I just chuck in some dried oregano or basil, depending on what’s closer)
- ¼ teaspoon garlic powder (optional, but I love it)
- ½ teaspoon fine sea salt (plus a bit for sprinkling, because salty edges are magic)
- 1 cup all-purpose flour (I go half whole-wheat if I’m feeling virtuous—up to you)
- ½ teaspoon baking powder
- 3 to 4 tablespoons water (I start with 3 and add just a smidge more if the dough's dry)
How You Piece it All Together
- Pop your oven on at 350°F (180°C). Get a big baking sheet out, and if you’re like me (hate sticking), put some parchment or a silicone mat on there. Actually, I tried straight on the tray once... don’t recommend. Major pan-scraping situation.
- In a roomy bowl, slosh together that sourdough discard and olive oil. Don’t worry if it looks a little lumpy; it always does at this point.
- Stir in the cheese, Italian seasoning, garlic powder, and salt. Give it a sniff—if it already smells pizza-ish, you’re winning.
- Sprinkle the flour and baking powder right over. This is where I sometimes forget to measure, but I eyeball—it hasn’t led me astray yet.
- Mix it all together. It'll get shaggy before it becomes a dough. Add water bit by bit (usually 3 tablespoons does it for me, but once I needed 4 when my starter was extra thick). You want a soft-ish but not sticky dough. If it’s sticky, just dust in a tad more flour.
- Flour your counter and plop out the dough. Roll it pretty thin—like ⅛ inch, or “thin enough to see shadows,” as my aunt used to say. Don’t stress about perfection, these are rustic crackers.
- Cut into squares, diamonds, or whatever shape speaks to your soul. I use a pizza wheel, but a sharp knife or even a bench scraper works. Transfer carefully (they stretch if you rush) onto the baking sheet.
- Poke each cracker with a fork a couple times, so they don’t balloon up. Sprinkle with a pinch more salt if you like a salty bite at the end—I always do.
- Bake about 18-22 minutes, turning the sheet once halfway through. Pull them when the edges are golden and you’re getting that pizza scent. If they look pale, let them go a smidge longer but don’t wander too far—burned cheese means sad crackers.
- Let them cool (as long as you can stand it, which for me is maybe 5 minutes). Snack away!
Stuff I’ve Learned (Probably From Making These Too Often)
- Actually, I find it works better if you roll the dough thinner than you think you should. The thicker ones are still nice, just more chewy than crispy.
- Don’t bother trying to make each cracker perfect—rustic is the vibe. Odd shapes just mean more crunchy edge bits.
- If you forget the Italian seasoning, plain crackers are still lovely. Been there, eaten that.
- PS: Once I stacked them on top of one another to “save space” on my baking tray. Nope. Stuck together in an un-crackerlike lump. Just don’t.
The Fun Experiments (aka Variations That Sometimes Work)
- Swap the parmesan for shredded cheddar (a bit more gooey, still good!). Mozzarella didn’t crisp up for me, but the flavor was fine.
- I tossed a pinch of red pepper flakes in the dough once. Warm kick—recommended.
- You can “paint” a bit of tomato paste on before baking, but it makes things a bit soft. Not my best idea, but the flavor was there for sure.
- Smoked paprika on top makes them taste a bit like fancy chips. Not everyone in my house agreed, though.
What You’ll Probably Use (and What to Do If You Don’t Have It)
- A rolling pin (or use a wine bottle—honestly I do this more than I want admit, especially if the rolling pin is hiding somewhere)
- A big baking tray
- Sharp knife or pizza cutter (a bench scraper does the job too, a bit clunkier but fine)
- Mixing bowl (for the lazy among us, a big saucepan works… I learned this when the bowls were all in the dishwasher)
Keeping Your Crackers (If You Can)
These store well in an airtight jar or tin for 2-3 days, but—hand on heart—they never last more than 24 hours around here. If you do manage to stash some, they perk up in a warm oven for a few mins. But stale ones do make a mean soup topper.
If You’re Looking to Serve (Here’s How I Like It)
I put out a bowl of warmed marinara or a squidge of pesto for dipping—not fancy, just good. My partner likes crushing them over salad for a surprise crunch. Oh, and after school, they disappear next to a pile of apple slices. Go figure.
My Pro Tips (Read: Things I’ve Messed Up Before)
- I once tried baking these at a lower temp to “make them crisper.” They went chewy, not crunchy. Just stick with the hot oven.
- Rushing the rolling step means uneven crackers—skinny ones burn while thick ones are kinda underdone. Take a mo to roll them evenly. Don’t skip this unless you like edible chaos (which, I mean, sometimes...)
Some of the Questions People (and My Little Sister) Have Asked
- Can I use starter that’s already been fed?
- Yeah, sure. Won’t have quite the tangy bite, but still good.
- My dough’s super sticky—did I mess up?
- Nope! Starters vary. Just dust with more flour until it’s workable. It’s not a crisis.
- Are these good for kids’ lunches?
- Absolutely. Though my youngest prefers them with less garlic powder. And more cheese. Classic.
- If I don’t have Italian seasoning, can I use something else?
- Use dried basil, oregano, even a sprinkle of za’atar has worked. Once I just chucked in some mixed herbs and nobody complained.
- Why are mine chewy not crispy?
- Either they need a couple more minutes in the oven, or they’re a bit thick. Back in they go, or roll thinner next time.
So there you are—pizza in cracker form! And if you’ve ever wondered what to do with that leftover sourdough starter, now you know (and your snack plate will thank you).
