I realized the other day as I was whipping up a batch of sourdough vegetable fritters that I was holding out on you.
While I’ve shared my easy sourdough artisan bread, a nice and soft sourdough sandwich bread, sourdough English muffins, crackers, and more – I hadn’t shared my favorite way to use up the discard I have when waking up my starter from the fridge (that’s how I keep starter when I’m not using it – you can read more about that here).
And by favorite, I mean I’ve been making a large batch of these sourdough vegetable fritters about every month.
They are that good.
So I apologize and hope this makes up for the lapse because I know you are going to want to keep this recipe to make again and again just like I do.

What is sourdough discard?
Discard is the portion of the starter you remove before feeding a newer starter (not brand new, but after the first week) or one you are waking up after keeping in the fridge for awhile. This keeps the starter strong and growing.
(Once the starter is strong and growing, you can just feed it without removing any until there’s enough to make a recipe you have.)
This discard will not be strong enough to raise bread, in which case you’ll want to use it for “discard recipes” like this one, crackers, or quick breads like sourdough lemon bread that don’t need to raise much or have other leavening like baking soda or powder.
So you don’t want to throw out discard from an established starter you’re waking up again – it’s still great for many things, it just has a confusing name.
(Note: you DO want to get rid of the discard from a NEW starter in the first 7 days, though – that’s when it’s establishing the good bacteria from the bad and you don’t know what’s in the discard).
There are so many reasons to love this sourdough fritter recipe, beyond the fact that we are using up our discard:
- First and foremost, they are delicious – really, really good.
- The recipe is so versatile – you can change up the veggies, spices, and cheese type (or leave it out entirely).
- I absolutely love that it uses up all those odds and ends of veggies that are languishing in the fridge.
- They store either in the fridge or freezer and reheat beautifully in a toaster oven or air fryer.
- They are great for any meal or snack: top with a fried egg for breakfast, eat with a salad for lunch, dip in spicy mayo for a snack, use as a side dish for dinner.

Sourdough Vegetable Fritters

Ingredients
- Sourdough discard (or regular starter)
- Vegetables of choice, grated or diced small (see more details on this in the FAQ section)

- Egg
- Garlic
- Spices
- Cheese, optional

Directions
The main work in this recipe is chopping the vegetables. Once that is done, you simply mix everything together thoroughly.
Since the amount of vegetables can vary with what you have on hand, I wanted to make sure you had a visual of what I aim for the dough to look like – the ratio of starter to veggies.
As you can see above, it should look like mostly vegetables being held together with some batter. If you have more batter than vegetables, it’s more of a pancake situation.

Once the batter is mixed, heat a nonstick pan or griddle with a couple tablespoons of oil and use a 1/4 cup, #16 cookie scoop to portion the fritters into the pan.
I like using a square electric skillet to fit five fritters at a time. When the kids were home, I’d use a large griddle but now the skillet works best for us – I can use if for more things and it takes up less room.
Cook (at about 350 degrees or medium heat) until deep brown on one side, about 5-7 minutes. Turn and cook until completely brown on other side.
Set on a cooling rack to cool as you continue cooking until the batter is all used.

Eat right away or store in fridge for a week. You can also freeze them for longer storage.
I’ve found that heating them in an air fryer for 5-7 minutes crisps them up again. A toaster oven should do a similar job.
Sourdough Discard Vegetable Fritters FAQ
Because the wild yeast partially consumes the gluten, it is easier to digest, has a lower glycemic index, provides healthy gut bacteria as a fermented food, and contains more vitamins, minerals, and antioxidants than other breads. (source)
Sourdough discard is fully fermented and highly digestible, which is why you want to find recipes to use it up.
If you can’t use the discard right away (or you want to build up your discard amount to make a big batch of fritters…), you can keep it in the fridge, covered, for 1-2 weeks. It may be thicker and more deflated and even have a bit of gray liquid on the top in the second week (hooch) but it’s perfectly safe to eat and will just have a more sourdough flavor.
Because they are cooked fairly rapidly, the best vegetables are softer, quicker cooking vegetables, though harder veggies can work if they are grated or diced very fine.
Here’s a list and how to prep them:
-Carrots, parsnips, turnips, beets: peel and grate (if using dark red beets, just be aware that the fritters will turn red)
-Onion, shallot, green onion: dice finely
-Cabbage: grate or finely chop
-Sweet peppers or mild hot peppers: finely chop (you can certainly use hot peppers – add to your own level of heat tolerance)
-Zucchini: grate onto a towel, roll up and squeeze before adding to starter mixture.
-Potato or sweet potato: peel and shred
-Corn: cut off cob or add frozen
-Greens like spinach, kale, and chard: chop very finely (some take the time to blanch them, but I have found they work fine in the fritters as long as they are chopped small).
-You can use broccoli, cauliflower as-is in the riced form, but they should be precooked if using fresh and chopped small. Making the fritters with leftover cooked vegetables like these and green beans is another great way to use up what you have.

Stumbled upon your blog because my friend makes your sourdough artisan loaf and gave me that recipe years ago. I wanted to check into it more recently and perused your recipes and found this one interesting. Last month my gfs and I went out to an Indian restaurant and had veggie fritters there so I had to try this. They’re currently in the pan and my husband is circling me because it smells SO GOOD! Out of the pan they come and we’re about to eat! I used carrots, yellow onion, sweet potato, sweet snap pepper, and cabbage and cooked in avocado oil. Great flavor and absolutely delicious!
Oh, I’m so glad you tried this! I love your combo – I haven’t thought about sweet potato before. Thank you for the review!!
