Got sourdough discard piling up in your fridge and a granola craving to match? This recipe solves both problems at once. It comes together in one bowl, bakes in 20 minutes, and holds up in the pantry for weeks.
Sourdough Granola Recipe
Crunchy, sweet sourdough discard granola with chunky clusters and a hint of tang. Ready in under 30 minutes with pantry staples you may already have in your kitchen.
- Total Time: 50-60 mins
- Yield: 4–6 servings (about 350g total) 1x
Ingredients
- 50g sourdough starter (active or discard, no older than 1–2 weeks)
- 20g honey or maple syrup
- 10g coconut oil, melted
- 5g vanilla extract
- 100g rolled oats
- 100g nuts and seeds (your choice)
- 2g cinnamon
- 1g nutmeg
- 2g salt
- 50g dried fruit
Instructions
- Preheat oven to 320°F (160°C). Line a baking sheet with parchment paper.
- In a large bowl, whisk the sourdough starter, honey, melted coconut oil, and vanilla extract until smooth.
- Stir in the oats, nuts and seeds, cinnamon, nutmeg, and salt until fully coated.
- Tip onto the lined baking sheet and press firmly into one even, compact layer.
- Bake 20 minutes, checking at 12-15 minutes since honey burns fast.
- If edges brown before the center is done, remove just the edge pieces and bake the center a few more minutes. Do not stir during baking.
- Cool completely on the tray, 20-30 minutes, undisturbed.
- Break into clusters and fold in the dried fruit.
- Store in an airtight container.
Notes
- Fresh discard only: Discard older than 1-2 weeks turns noticeably sour once baked.
- Don’t stir while baking: This is what keeps the clusters chunky instead of crumbly. Press hard before it goes in, then leave it alone.
- Fruit goes in last: Adding dried fruit before baking dries it out and risks burning.
- Storage: Keeps 2-3 weeks at room temp in an airtight container (best for freshness) or a sealed glass jar (best for crunch). Must be fully cooled before sealing.
- Doubling: Split across two trays rather than piling thicker on one, or the center won’t crisp.
- Prep Time: 10 mins
- Cook Time: 20-30 minutes

Why Use a Sourdough Starter in Granola?
Most granola recipes rely on egg whites or extra sugar to hold everything together. Sourdough starter does the same job, minus the extra ingredients you’d need to buy.
As it bakes, the starter thickens and binds the oats, nuts, and seeds into solid clusters instead of loose crumbs.
You’ll need to ensure that your starter is a few weeks old, then remove a small portion of the starter to use in this recipe.
And if you want your granola chunkier, you can add more honey or maple syrup. The extra stickiness helps everything clump together into bigger, more satisfying pieces.
Should I Use Active Starter or Discard
Either works BUT freshness matters more than which one you pick.
- Active starter: Use it straight from a recent feeding for the mildest, most balanced flavor.
- Discard: Fine to use, as long as it’s no more than a week or two old. Older discard turns noticeably more sour, and that flavor comes through strong once baked.
Skip discard that’s been sitting for a month or more. It won’t ruin the granola, but it will make it taste sharper than what you might expect from a breakfast food.
Sourdough Discard Granola Recipe
Sourdough granola is super quick and easy to pull together. The only challenging part of this recipe is committing to the type of nuts and seeds you’d like!
You can use anything you wish, from raisins and dried pumpkin seeds to chopped dried apricots.
Here’s how to make this delicious granola mix:
Ingredients
| Ingredient | Amount | Approx. Measure |
|---|---|---|
| Sourdough starter (active or discard) | 50g | ~3 tbsp |
| Honey or maple syrup | 20g | ~1 tbsp |
| Coconut oil, melted | 10g | ~2 tsp |
| Vanilla extract | 5g | ~1 tsp |
| Rolled oats | 100g | ~1 cup |
| Nuts and seeds, your choice | 100g | ~¾ cup |
| Cinnamon | 2g | ~1 tsp |
| Nutmeg | 1g | ~¼ tsp |
| Salt | 2g | ~⅓ tsp |
| Dried fruit | 50g | ~⅓ cup |
Swap in whatever’s in your pantry, and don’t sweat it if you don’t have the exact ingredients.
How to Make Sourdough Discard Granola
- Preheat the oven to 320°F (160°C) and line a baking sheet with parchment paper.
- Mix the wet ingredients. In a large bowl, whisk together the sourdough starter, honey (or maple syrup), melted coconut oil, and vanilla extract until smooth.
- Add the dry ingredients. Stir in the oats, nuts and seeds, cinnamon, nutmeg, and salt. Mix until every oat is coated in the wet mixture.
- Press it onto the tray. Tip the mixture onto your lined baking sheet and press it down firmly into one even, compact layer. This step is what creates those big, chunky clusters, so don’t rush it or skip it.
- Bake for 20 minutes. Check around the 12 to 15 minute mark. Honey scorches fast, so keep an eye on the color.
- Watch the edges. If the outer edges turn golden before the center is done, pull the tray out, break off just the finished edge pieces, and slide the tray back in for a few more minutes to crisp the middle. Leave the granola undisturbed the rest of the time; stirring while it bakes will break apart the clusters you just pressed together.
- Cool completely. Let the granola sit on the tray for 20 to 30 minutes without touching it. It firms up and crisps as it cools, not while it’s hot.
- Add the fruit. Once fully cool, break the granola into clusters and fold in the dried fruit.
- Store in an airtight container.
Tips for the Best Sourdough Granola
Now, this sourdough granola recipe is incredibly simple to prepare, but these recipe tips might help:
- Use whatever mix-ins you have in your pantry. Pumpkin seeds and raisins or almonds and chopped apricots? It’s all good.
- Bake the granola slow, on low heat, so that the mixture doesn’t burn easily.
- If the edges of your granola are golden, but the middle seems a little undercooked, simply break away the edges and remove them. Pop the middle section back into the oven for a few minutes.
- Only add the dried fruit after the granola has baked and cooled.
Troubleshooting When Something Goes Wrong
| Problem | Why It Happens | Fix |
|---|---|---|
| Granola is crumbly, not clustered | Mixture wasn’t pressed firmly, or it was stirred during baking | Press hard before baking; leave it alone while it’s in the oven |
| Edges burnt, center still soft | Honey caramelizes fast along thin edges | Break off and remove the edges, then bake the center a few extra minutes |
| Flavor is too sour | Discard was old | Use discard within a week or two of its last feeding |
| Granola never fully crisps | Pulled from the oven too early, or fruit added before baking | Bake until golden, cool fully before breaking apart, and add fruit last |
Storing Your Granola
Once fully cooled, granola keeps well in either an airtight container or a glass jar on the counter.
- Airtight container: Best for keeping it fresh over time.
- Glass jar: Best for keeping that crunch, since glass doesn’t trap moisture the way some plastics can.
Either way, granola stays good for about two to three weeks at room temperature. Make sure it’s completely cool before sealing it up, or trapped steam will soften those clusters you worked for.
Other Flavors and Variations to Try
Once you’ve made the base recipe once, swapping in new flavors is easy. Use the same method above and just adjust these ingredients:
| Variation | Swap the Nuts/Seeds For | Swap the Spices For | Add After Baking |
|---|---|---|---|
| Honey Oat | 50g raw almonds + 50g rice cereal | Increase honey to 40g | Nothing, skip the dried fruit |
| Maple Pecan | 100g chopped pecans | Use maple syrup instead of honey | Nothing extra needed |
| Apricot Almond | 70g raw almonds | Remove cinnamon and nutmeg | 100g chopped dried apricots, then 50g flaked almonds |
| Chocolate Coconut | 100g shredded coconut | 20g cocoa powder instead of spices | 40-60g mini chocolate chips (once fully cooled) |
| Apple Cinnamon | 100g walnuts | Add an extra 4g cinnamon | 100g dried apple pieces |
| Pumpkin Spice | 50g pecans + pumpkin seeds | 2 tsp pumpkin pie spice | 100g dried cranberries |

Sourdough Granola FAQs
When should I add dried fruit to granola?
Always after baking, once the granola has cooled completely. Adding it beforehand means the fruit dries out and can burn under the oven’s heat.
My granola won’t stick together. What went wrong?
Usually one of two things: not enough pressing before baking, or stirring during the bake. Press the mixture into a firm, even layer, and resist the urge to check on it by stirring.
Do I need to stir the granola while it bakes?
No. Press the mixture firmly onto the tray before it goes in, then leave it undisturbed for the full bake. Stirring breaks apart the clusters and leaves you with loose crumbs instead of chunky granola. If the edges brown too fast, remove just those pieces rather than stirring the whole tray.
Can I use an old sourdough discard?
You can, but the flavor gets more sour the older it is. Stick to discard that’s a week or two old at most for a milder, more balanced taste.
Is sourdough granola actually healthy?
It’s a solid source of fiber and healthy fats from the oats, nuts, and seeds, with less added sugar than most store-bought granola. Portion size still matters since nuts and dried fruit are calorie-dense, but as far as breakfast or snack options go, this one holds its own.
How long does homemade granola last?
About two to three weeks at room temperature in an airtight container or sealed glass jar, as long as it’s fully cooled before storing.
Can I double the recipe?
Yes, just use a larger baking sheet or split the mixture across two trays. Piling it too thick on one pan means the center won’t crisp properly, no matter how long it bakes.
