  • Taste and texture: There is an awesome blend of sweet, spice, tart, and tangy in this recipe. Nothing beats a gooey, warm, delicious apple crisp.

  • Pros: Your house will smell amazing while this apple crisp bakes. It is also an easy way to use up your sourdough discard.

🍎 Ingredients needed

The ingredients needed to make sourdough apple crisp.

For this sourdough apple crisp, you will need:

  • Apples: So many different types of apples work in this recipe. You can use Golden Delicious, Honey Crisp, Braeburn, Honey Crisp, Granny Smith, Fuji, or Gala. Really almost any apple will work in this recipe. Whatever apple you choose, be sure not to cut it too small. If your apple pieces are too small it can cause your apple crisp to become watery.
  • Brown Sugar
  • All purpose flour
  • Quick oats: Or you can substitute old fashioned oats.
  • Cinnamon and nutmeg:
  • Butter: I recommend using unsalted.
  • Sourdough discard: I used discard but you can also use active starter.

🥧 Variations

  • You can use a mixture of apple varieties, if you like.
  • You can add some chopped walnuts or pecans on top, if desired.

🍦 What to serve with this recipe

You can serve this apple crisp as is or add vanilla ice cream or whipped cream on top.

👩🏻‍🍳 Tips

  • Do not cut your apples too small. If they are too small, they will make your crisp watery.
  • Try using freshly grated nutmeg.
  • Cooking times may vary depending on your oven. You’ll know the apple crisp is done when the apples are bubbling and the topping is golden brown and crisp.

🥡 How to store leftovers

Any leftover apple crisp can be stored in your refrigerator for up to four days after making.

❔FAQS

Why use sourdough discard in recipes?

Sourdough discard still has tangy sourdough notes in it. Sourdough bakers will appreciate this awesome flavor. Sourdough baking isn’t just about the bread, there are many wonderful sourdough discard recipes out there.

Using sourdough discard is also an easy way to reduce kitchen waste.

What is the difference between sourdough starter and sourdough discard?

Active starter is sourdough starter that has been fed a mixture of water and flour. It is allowed to sit at room temperature thus it becomes bubbly and grows in size.

Sourdough discard is the unfed part of your sourdough starter. You remove the discard before feeding it flour and water. Because it has not been fed, you wouldn’t use it to bake bread with (it wouldn’t be strong enough). You can use it in sourdough discard recipes and it will still have some tangy sourdough notes.

How do you get sourdough discard?

You get sourdough discard by removing a portion of your starter before feeding it. You do this because if not, you will get a giant sourdough starter that will be difficult to maintain and feed.

You can keep the discard in a Tupperware container or glass jar and then use it in discard recipes. You can even freeze your discard for later use.

How long is sourdough discard good for in the fridge?

Sourdough discard kept in the fridge is good as long as it isn’t moldy. I recommend using within the first five days of discarding because the longer it sits, the more acidic it will become. The acidity can affect the flavor of your discard recipes, especially sweet ones.

    Very good! Only thing I’d change is add additional sugar and cinnamon to the apples then the topping. They just need a little extra flavor.

    I’m always looking for ways to use my discard and this recipe didn’t disappoint. My family loved it. I served it warm with ice cream. This is now my go to when I have apples to use up.

    This is a good apple crisp and super easy. I also love that I can use discard! I am not excited about the texture of the topping (not crumbly) but I’m sure that’s because it has the discard in it. I would also add salt next time. It is tasty though; will make again.
