This apple crisp is a baked dessert of tender cinnamon apples under a crunchy, buttery oat topping. It takes about 20 minutes to prepare and 40 to 50 minutes to bake, and one 9 by 13 inch (23 by 33 cm) dish serves about 8.
Why This Apple Crisp Works
A mix of tart and sweet apples gives the filling real flavor, lemon juice keeps it bright, and two tablespoons of flour thicken the juices so the fruit does not turn watery. The topping uses cold butter, which melts slowly in the oven and leaves crisp clusters instead of a greasy layer. If you like apples in other forms, the apple cinnamon french toast on this site uses the same warm spice profile.
Ingredients
For the filling
- 6 medium apples (about 2 pounds or 900 g), peeled, cored, and sliced about 1/4 inch (6 mm) thick
- 2 tablespoons lemon juice
- 1/4 cup (50 g) granulated sugar
- 2 tablespoons all-purpose flour
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon salt
For the topping
- 1 cup (80 g) old-fashioned rolled oats
- 3/4 cup (95 g) all-purpose flour
- 1/2 cup (100 g) packed brown sugar
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 1/2 cup (113 g) cold unsalted butter, cut into small cubes
Method
- Heat the oven to 350°F (175°C) and lightly grease a 9 by 13 inch (23 by 33 cm) baking dish.
- Toss the apples with the lemon juice, sugar, flour, cinnamon, nutmeg, and salt until no dry flour is visible. Spread them evenly in the dish.
- In a separate bowl, stir together the oats, flour, brown sugar, cinnamon, and salt. Add the cold butter and rub it in with your fingertips until the mixture looks like coarse crumbs with some pea-sized clumps.
- Scatter the topping over the apples and press it down lightly, so it covers the fruit but stays loose.
- Bake for 40 to 50 minutes, until the topping is deep golden and the juices bubble thickly around the edges. If the top browns before the juices bubble, cover it loosely with foil.
- Rest for at least 15 minutes. The juices thicken as the crisp cools, which gives a spoonable filling instead of a runny one.
Troubleshooting
| Problem | Likely cause | Fix |
|---|---|---|
| Watery filling | Juicy apples, too little flour, or no resting time | Keep the 2 tablespoons of flour, bake until the juices bubble thickly, and rest 15 minutes before serving |
| Soggy topping | Butter was warm, or the topping was packed down hard | Use cold butter, leave pea-sized clumps, and press the topping only lightly |
| Mushy apples | Soft apple variety or slices cut too thin | Choose firm apples and slice about 1/4 inch (6 mm) thick |
| Topping dark before the fruit is soft | Oven runs hot or the dish sits too high | Tent loosely with foil and bake on the middle rack |
Choosing Apples and Swaps
Firm apples hold their shape in the oven. Use a tart variety for brightness and a sweeter one for softness. Very soft apples break down into sauce, which tastes good but loses the tender slices that make a crisp satisfying.
- Add 1/2 cup (60 g) chopped pecans or walnuts to the topping for extra crunch.
- Swap half the apples for pears.
- Stir a handful of dried cranberries into the filling.
- For a gluten-free version, use certified gluten-free oats and a gluten-free flour blend in both parts.
- No nutmeg? Use another 1/4 teaspoon of cinnamon.
Serve it warm with vanilla ice cream or lightly sweetened whipped cream. For another fruit dessert with a crumbly top, try the peach cobbler, or put the creamy apple dip on the same dessert table.
Make Ahead, Storage, and Reheating
Cover the cooled crisp and refrigerate it for up to 3 days. The topping softens as it sits, which is normal. To bring back the crunch, reheat portions in a 350°F (175°C) oven for 10 to 15 minutes, until warm in the center. The microwave is faster, but the topping stays soft.
To assemble ahead, keep the topping in a covered container in the refrigerator and the dressed apples in their dish, then combine and bake when you are ready. Baking from cold may take a few extra minutes.
FAQ
What is the difference between apple crisp and apple crumble?
A crisp topping usually contains oats, while a crumble is typically made from flour, butter, and sugar alone. In practice the two names are often used for the same dessert.
Can I freeze apple crisp?
Yes. Freeze the baked and fully cooled crisp, wrapped tightly, then thaw it in the refrigerator overnight and reheat in a 350°F (175°C) oven until warm. The topping will be a little softer than when fresh.
Do I have to peel the apples?
No, but the peel softens less than the flesh and can feel chewy. Peeling gives the most tender, even filling.
How do I know when apple crisp is done?
Look for a deep golden topping and juices that bubble thickly at the edges. A fork should slide easily into the apples.
