You know that moment when you peek into your sourdough starter jar and think, “Ugh, I should feed you… but I just can’t deal with another loaf today”? That’s exactly how these seeded sourdough discard crackers were born in my kitchen – out of guilt, laziness, and a serious craving for something crunchy. I’m Martavia, a chef who believes good food shouldn’t be complicated, and these crackers prove it. They transform that sad discard (you know, the stuff you’d normally toss) into the most addictive, seedy little crisps with just minutes of hands-on work. The best part? They make your house smell like a cozy bakery while baking – bonus points if you eat them warm with a schmear of butter while pretending to be fancy.

Why You’ll Love These Seeded Sourdough Discard Crackers
Okay, let me tell you why these little guys are about to become your new obsession. First off – that crunch! They bake up so crispy, you’ll hear the satisfying snap from across the room. Second, they’re the ultimate zero-waste win – turning that discard into something delicious instead of down the drain. Third, the seed mix is totally your call – I go wild with pumpkin and sunflower, but you do you. And the best part? From bowl to baking sheet in 15 minutes flat – perfect for when snack emergencies strike.
Ingredients for Seeded Sourdough Discard Crackers
Let’s talk ingredients – and I mean real talk, like “is your sourdough discard looking a little sad in the fridge?” kind of talk. This recipe is so forgiving, but a few key players make all the difference. You’ll need:

- 220 grams (about 1 cup) of that neglected sourdough discard – doesn’t matter if it’s fresh or been chilling for days
- 50 grams (¼ cup) good olive oil – the kind you’d drizzle on bread, not the “emergency only” bottle
- 125 grams (1 cup) all-purpose flour – spoon it in, don’t pack it down
- The seed squad: 45g each of raw sunflower and pumpkin seeds (that’s heaping ¼ cups), plus 18g (2 tablespoons) each of sesame and flaxseed or hemp hearts
- 2 grams (½ teaspoon) coarsely ground black pepper – trust me, that pop of spice is clutch
- 1 gram (¼ teaspoon Diamond Crystal or ⅛ teaspoon Morton) kosher salt – yes, we’re getting that specific because salt matters
- Flaky sea salt for sprinkling – optional but oh-so-worthy
Pro tip: Measure your seeds by weight if you can – seeds vary wildly in size, and we want that perfect crunch ratio!
How to Make Seeded Sourdough Discard Crackers
Okay, let’s get our hands dirty – literally! These crackers come together so fast, you’ll be snacking before you know it. Just follow these simple steps, and you’ll have the crunchiest, seediest little delights in no time.

Mixing the Dough
First things first – crank that oven to 325°F (165°C) and let it preheat while we work. Now, grab a large bowl and dump in your sourdough discard and olive oil. Give it a good stir until it looks like a weird, bubbly soup – that’s perfect! In another bowl, mix together all your dry ingredients – flour, seeds, pepper, and salt. Here’s where the magic happens: dump the dry into the wet and stir with a fork until it looks like a shaggy mess. Don’t worry if it seems dry at first – keep mixing and it’ll come together. When it does, get your hands in there and knead it just until it forms a sticky ball. The seeds should be evenly distributed – no seed left behind!
Rolling and Cutting
Now for the fun part! Tear off a big piece of parchment paper (about the size of your baking sheet) and lightly flour it. Plop your dough right in the center and pat it flat with your hands. Grab a rolling pin and go to town, rolling it out into a big rectangle – aim for about 16×12 inches and super thin, like 1/16 to ⅛ inch thick. The thinner, the crispier! Sprinkle with that flaky salt if you’re using it, then gently roll over it once more to press the salt in. Transfer the whole parchment with your dough onto your baking sheet. Now, take a pizza cutter or sharp knife and cut into squares – about 40 little crackers. No need to separate them – they’ll break apart after baking.
Baking and Cooling
Slide that pan into the oven and set a timer for 15 minutes. When it dings, rotate the pan – this ensures even baking. Bake for another 15-20 minutes until they’re golden brown and look dry. Here’s the hardest part: let them cool completely on the pan! I know it’s tempting to dig in, but they crisp up as they cool. Once they’re room temp, break them apart along your cut lines. Now try not to eat them all in one sitting – I dare you!

Tips for Perfect Seeded Sourdough Discard Crackers
Listen, I’ve made enough batches of these crackers to know where things can go wrong – and how to fix them! First up: rolling thickness. If your crackers bake up chewy instead of crisp, you probably rolled them too thick. Aim for that credit-card thinness – about 1/16 inch. Second, watch your seed distribution. If you notice bare spots in your dough, pause halfway through rolling to flip and fold it like a letter before continuing – this redistributes the seeds beautifully.
Storage is key too! These guys stay crispy for days in an airtight container at room temp – just toss in a silica packet if your kitchen’s humid. And here’s my secret weapon: bake a double batch and freeze half. A quick 5-minute toast in the oven brings them right back to life!
Variations for Seeded Sourdough Discard Crackers
One of my favorite things about these crackers? They’re a blank canvas for your pantry adventures! Swap out the seeds with whatever you’ve got – chia seeds add fun little pops, while everything bagel seasoning turns them into brunch-worthy bites. Feeling spicy? Toss in some red pepper flakes or smoked paprika. For gluten-free friends, just use your favorite 1:1 GF flour blend – it works like a charm. And if you’re feeling extra, try adding a tablespoon of nutritional yeast for a cheesy twist. The possibilities are endless!
Serving Suggestions
Oh, the places these crackers will go! My absolute favorite way is warm from the oven with a swipe of creamy goat cheese and a drizzle of honey – pure magic. They’re also killer with hummus, or crumbled over soup for crunch. For parties, I arrange them with sliced cheeses and call it “rustic charcuterie” (wink). A standard serving is about 5 crackers, but let’s be real – you’ll lose count after the first handful!
Storing Seeded Sourdough Discard Crackers
Here’s the beautiful thing about these crackers – they actually stay crispy for days! Just pop them in an airtight container (I’m obsessed with my glass cookie jar for this) at room temperature, and they’ll keep their crunch for up to 1 week. If your kitchen runs humid, toss in one of those silica packets from your seaweed snack bags – works like a charm! For longer storage, freeze them in a zip-top bag and revive in a 300°F oven for 5 minutes when the craving hits.
Nutritional Information
Now, let’s chat numbers – but remember, these are just estimates since your exact seeds and flour might vary a bit. For about 5 crackers (my suggested serving size, though good luck stopping there!), you’re looking at roughly 120 calories, 6g of healthy fats from all those glorious seeds and olive oil, and 2g of fiber to keep you satisfied. Not too shabby for something that tastes this indulgent! Of course, if you go wild with the flaky salt topping or cheese pairings, those numbers will climb – but hey, we’re all about balance, right?
FAQ About Seeded Sourdough Discard Crackers
Let’s tackle those burning questions I get all the time about these addictive little crackers! First up: Can you freeze them? Absolutely! Just cool them completely, then stash in a freezer bag for up to 3 months. When you’re ready, pop them straight into a 300°F oven for 5 minutes – they’ll crisp right back up like magic.
Can I use active starter instead of discard? Technically yes, but here’s the thing – active starter will make your crackers puff up more, losing some of that signature crispness. The discard’s acidity actually helps create that perfect snap! If you must use active starter, reduce the flour by about 10 grams to compensate.
Help! I don’t have all the seeds! No sweat – this recipe is crazy flexible. Use whatever seeds you’ve got in equal amounts by weight. I’ve made killer batches with just sesame and pepitas, or even thrown in some chopped nuts when I was desperate. The only rule? Keep the total seed weight about the same (around 125g) for the perfect crunch-to-dough ratio.
There you have it – your new favorite way to rescue that sourdough discard from the compost bin! These seeded crackers are proof that the simplest ingredients can create something truly special. I’d love to hear how your batch turns out – did you stick with my seed mix or go wild with your own creations? Snap a pic of your crackers and tag me @Dishivia so I can see your handiwork!
