There’s nothing quite like the aroma of warm apples, cinnamon, and buttery crumble filling the kitchen. The first time I made Sourdough Discard Apple Crisp, I wanted to turn a jar of leftover sourdough discard and a basket of fresh apples into a cozy dessert everyone would enjoy.

The result was even better than I expected. The apples baked into a soft, cinnamon-spiced filling while the buttery sourdough crisp topping turned perfectly golden and crunchy. Served warm with a scoop of vanilla ice cream, it quickly became a family favorite. Now Sourdough Discard Apple Crisp is one of my go-to desserts for fall gatherings, holiday dinners, or whenever I’m craving an easy homemade treat.

Ingredients for Sourdough Discard Apple Crisp

Ingredient Notes

• Sourdough Discard: Unfed sourdough discard adds a subtle tangy flavor that balances the sweetness of the apples while creating a tender, flavorful crumble.

• Apples: Honeycrisp, Granny Smith, Braeburn, or Pink Lady apples hold their shape well during baking and provide the perfect balance of sweetness and tartness.

• Old-Fashioned Rolled Oats: Oats create the classic crisp topping with a hearty texture and buttery crunch.

• All-Purpose Flour: Helps bind the crumble together while keeping the topping light and crisp.

• Brown Sugar: Adds rich caramel flavor to both the apple filling and the crumble topping.

• Ground Cinnamon: Gives the crisp its warm, comforting flavor that pairs perfectly with baked apples.

• Unsalted Butter: Cold butter creates a crumbly topping that bakes into crisp, golden clusters.

• Vanilla Extract: Enhances the sweetness of the apples and adds depth to the filling.

• Lemon Juice: Brightens the apple flavor and helps prevent the apples from browning before baking.

• Salt: A small pinch balances the sweetness and enhances all the flavors.

With these simple ingredients, you’ll create Sourdough Discard Apple Crisp with a bubbling apple filling and a buttery golden topping that’s perfect for serving warm with vanilla ice cream or freshly whipped cream.

How to Make Sourdough Discard Apple Crisp

Making Sourdough Discard Apple Crisp is incredibly easy. The juicy apple filling comes together in minutes, while the buttery sourdough crumble bakes into a crisp, golden topping that’s perfect for serving warm with vanilla ice cream.

1. Prepare the Oven and Baking Dish

• Preheat your oven to 350°F (175°C).

• Lightly grease a 9-inch baking dish or a 2-quart casserole dish with butter or nonstick cooking spray.

2. Make the Apple Filling

In a large mixing bowl, combine:

• Peeled and diced apples
• Brown sugar
• Ground cinnamon
• Vanilla extract
• Lemon juice
• A pinch of salt

Toss everything together until the apples are evenly coated.

Spread the apple mixture into the prepared baking dish.

3. Prepare the Crisp Topping

In another bowl, combine:

• Old-fashioned rolled oats
• All-purpose flour
• Brown sugar
• Sourdough discard
• Ground cinnamon
• Cold cubed butter

Mix with a pastry cutter or your fingertips until the mixture forms coarse, buttery crumbs.

4. Assemble the Crisp

• Evenly sprinkle the crumble topping over the apples, covering the entire surface without pressing it down.

• The loose topping will bake into crisp, golden clusters.

5. Bake

• Bake for 40 to 45 minutes, or until the apple filling is bubbling around the edges and the topping is golden brown and crisp.

• If the topping begins browning too quickly, loosely cover the dish with foil during the final 10 minutes.

6. Cool and Serve

• Allow the Sourdough Discard Apple Crisp to cool for 10 to 15 minutes before serving.

• Enjoy it warm with vanilla ice cream, whipped cream, or a drizzle of caramel sauce.
