How to Make Sourdough Apple Crisp
Peel and thinly slice the apples into small chunks and arrange them in a 9×13-inch baking dish or 12-inch cast iron skillet and set aside.

Add white sugar, rolled oats, and spices to a large bowl and stir until combined.

Then add the room temperature or melted butter and sourdough discard to the dry ingredients and mix until you have a stiff dough. Use your hands if necessary.

Add your sourdough crisp topping to the juicy apples and press the mixture onto the apples.

Common Questions
The best apples are firm apples for this recipe. We use a mix of tart Granny Smith apples and Honeycrisp or Pink Lady but any apple you like or have on hand will work. We prefer to mix sweet and tart apples together.
Yes, you can use the same amount of active starter in place of discard.
Absolutely! While apple crisp is traditionally made with apples, you can easily incorporate other fruits like pears, berries, or peaches.
f you prefer to skip the oatmeal in the topping, you can use a simple combination of butter, flour, and sugar for a buttery, crumbly topping.
How To Reheat and Store Leftovers
To store sourdough apple crisp, first let it cool completely to room temperature. Once cooled, cover the dish tightly with plastic wrap or transfer the crisp to an airtight container. You can store it in the refrigerator for up to 3–4 days.
To reheat the apple crisp the next day or later and maintain its crispness, preheat your oven to 350°F. Place the crisp in an oven-safe dish and cover it loosely with aluminum foil to prevent the top from over-browning.
Heat for about 15–20 minutes, or until warmed through, removing the foil for the last few minutes of heating can help re-crisp the topping. Avoid using the microwave, as it can make the topping soggy instead of crisp.
This easy sourdough apple crisp recipe combines the comforting flavors of a classic apple crisp with a unique twist using sourdough discard. The tangy notes from the sourdough perfectly complement the sweet, spiced apples and buttery, crunchy topping, making it delicious recipe for fall.
With its simple ingredients and straightforward preparation, this recipe is perfect for using up extra sourdough discard while creating a delicious treat for your family.
