How to Make Baked Apple Crisp with Oat Topping

Preheat Oven: Preheat to 350°F (175°C) so your oven is ready and evenly heated before baking. This ensures a golden oat topping and perfectly tender apples.
For the Apple Filling:
Peel and Slice Apples: Peel, core, and slice 6 cups of Honeycrisp apples into 1/4-inch wedges for consistent size and mouthwatering tender texture after baking.
Toss with Spices: In a bowl, gently toss apples with sugar, cinnamon, lemon juice, and cornstarch until evenly coated and juices begin to lightly thicken.
For the Oat Topping:
Combine Dry Ingredients: In a bowl, stir oats, flour, brown sugar, and nutmeg until fully blended in warm browns for a classic hearty mixture.
Cut in Butter: Use cold, diced butter and a pastry cutter (or fingers) to work into the dry mix until pea-sized clumps form.
Assemble Crisp: Spread apple filling evenly in a 9×13-inch baking dish, then sprinkle oat topping to cover every piece of fruit.
Bake Until Golden: Bake at 350°F (175°C) for 40–45 minutes until the topping is crisp and golden brown, and the filling is bubbly.
Cool and Serve: Let rest 10 minutes so juices set. Serve warm with ice cream, whipped cream, or a spoonful of yogurt.

Optional: Drizzle caramel sauce over each serving for extra coziness.

Expert Tips for Baked Apple Crisp with Oat Topping

Choose the Right Apples: Use firm, crisp apples like Honeycrisp to ensure a juicy filling that holds its shape without turning to mush.
Don’t Overmix Topping: When cutting in butter, stop once pea-sized clumps form to keep the oat topping light and crumbly, avoiding a dense crust.
Even Apple Slices: Slice apples uniformly (about 1/4-inch thick) for consistent cooking and a perfectly tender texture throughout your baked apple crisp with oat topping.
Prevent Soggy Bottoms: Toss apples with cornstarch and sugar thoroughly to thicken juices, preventing a watery filling that can make the bottom soggy.
Bake on Middle Rack: Position your dish in the center of the oven to allow even heat circulation, helping the topping brown beautifully without burning.
Rest Before Serving: Let the crisp cool 10 minutes so the juices thicken slightly, making each spoonful comforting and neat rather than runny.

Make Ahead Options

Preparing your Baked Apple Crisp with Oat Topping ahead of time is a game-changer for busy weeknights! You can slice your Honeycrisp apples and toss them with sugar, cinnamon, lemon juice, and cornstarch up to 24 hours in advance. Store the apple mixture in an airtight container in the refrigerator to keep them fresh and prevent browning. You can also combine the dry ingredients for the oat topping and refrigerate them separately in a sealed bag for up to 3 days. When you’re ready to bake, simply layer the apple mixture in the baking dish, sprinkle the oat topping on top, and pop it in the oven as directed. This way, you ensure a comforting dessert that’s just as delicious with minimal effort!

Store your leftover crisp in an airtight container in the refrigerator, where it will keep delicious for up to 5 days. If you want a quick treat, just reheat in the oven to bring back that crunchy oat top.
