Old-Fashioned Apple Crisp with Oats

This old-fashioned apple crisp recipe with oats brings together tender, cinnamon-scented apples and a generous buttery oat topping. It is the kind of dessert that makes the kitchen smell inviting while it bakes, and it is especially good served warm with vanilla bean ice cream or whipped cream.

The recipe uses a simple 8×8-inch baking dish and takes about 15 minutes to prepare. The apples are tossed with sugar, cinnamon, and lemon juice, then covered with a crumbly mixture of brown sugar, oats, flour, butter, cinnamon, and salt. After 40 to 50 minutes in a 350°F oven, the topping should be golden and the filling bubbly.

Why You’ll Love This Apple Crisp

This apple crisp recipe with oats has the cozy flavor of a classic fall dessert without requiring a complicated pastry crust. The apples provide a soft, fruit-filled base, while the oat topping gives each serving a contrasting crisp, buttery texture.

You can choose the apples you like best. Golden Delicious apples are a favorite option for this recipe, while Granny Smith and Fuji apples also work well. The apples may be peeled or left unpeeled, so you can choose the texture and appearance your household prefers. If you leave the skins on, wash the apples thoroughly first.

The topping is also flexible in one small way: old-fashioned oats are the standard choice, but quick oats can be used if needed. The texture may be a little different, but the topping will still bring the oat flavor and crumbly contrast that make this dessert so appealing.

Ingredients

For the spiced apples

• 6 Golden Delicious apples, peeled and chopped: You can use other apple varieties, or slice the apples instead of chopping them. Six apples yield approximately 6 to 7 cups of chopped fruit.
• 2 tablespoons granulated sugar: This lightly sweetens the apple layer.
• ¾ teaspoon ground cinnamon: Toss it with the apples for warm spice throughout the filling.
• 1½ teaspoons lemon juice: Add it to the apple mixture before baking.

For the oat topping

• 1 cup light brown sugar
• ¾ cup old-fashioned oats: Quick oats may be used, although they can give the topping a slightly different texture.
• ¾ cup all-purpose flour
• 1 teaspoon ground cinnamon
• A pinch of kosher salt
• ½ cup cold unsalted butter, diced into small cubes: Keeping the butter cold helps it break into small pieces throughout the topping mixture.

You will also need butter or nonstick cooking spray for the 8×8-inch baking dish, plus a mixing bowl, vegetable peeler, and pastry cutter. Two forks or clean hands can be used instead of a pastry cutter.

How to Make Apple Crisp

1. Prepare the baking dish

Heat the oven to 350°F. Butter an 8×8-inch baking dish or coat it with nonstick cooking spray, then set it aside while you prepare the apples and topping.

2. Make the spiced apples

Place the chopped apples in a mixing bowl. Add the granulated sugar, ¾ teaspoon cinnamon, and lemon juice. Stir until the apples are evenly coated, then transfer them to the prepared baking dish and spread them into an even layer.

3. Make the oat topping

In a separate bowl, combine the brown sugar, oats, flour, 1 teaspoon cinnamon, kosher salt, and diced cold butter. Use a pastry cutter with a slight downward twisting motion to work the butter into the dry ingredients. Continue until the mixture resembles pea-sized crumbs.

If you do not have a pastry cutter, use two forks or work the butter into the mixture with your hands. The goal is a coarse, crumbly mixture with small pieces of butter distributed through it, rather than a smooth dough.

4. Top and bake

Scatter the topping evenly over the apples. Gently pat it into an even layer without packing it down firmly. Bake for 40 to 50 minutes, or until the topping is golden brown and the apple filling is bubbly.

5. Serve warm

Let the crisp cool enough to serve safely, then spoon it into bowls while it is still warm. Finish it with vanilla bean ice cream or whipped cream if you like.

Tips for Success

• Use the apple shape you prefer. Chopped apples create small pieces throughout each serving, while sliced apples give the filling a more defined structure. Both options are included in the recipe guidance.
• Peel or leave the skins on. Either approach works. If you keep the skins, wash the apples thoroughly before cutting them.
• Keep the butter cold. Diced cold butter is easier to cut into the oats, flour, and sugar until the mixture forms pea-sized crumbs.
• Watch the visual cues. Ovens bake differently, so the crisp may need a little less or a little more time than the 40-to-50-minute range. Look for a golden topping and bubbling fruit rather than relying on the clock alone.
• Address extra juice if needed. Apples release water as they bake. If you want to avoid a little juice collecting at the bottom, the supplied tip is to add a small amount of all-purpose flour to the apple mixture.
• Let the topping stay crumbly. Pat it gently into place so the mixture remains a topping instead of turning into a compact layer.

Variations and Substitutions

The easiest variation is changing the apples. Golden Delicious, Granny Smith, and Fuji are all named options, and the recipe also allows you to use other apples you enjoy. You can chop the fruit or slice it, depending on the texture you want in the finished dessert.

For the topping, old-fashioned oats provide the stated texture, but quick oats can be substituted. The result may have a slightly different texture. The recipe is written with all-purpose flour and unsalted butter, so do not treat other flour or butter changes as exact equivalents without adjusting based on how the mixture looks and handles.

For serving, vanilla bean ice cream and whipped cream are both supported choices. A drizzle of browned butter salted caramel sauce is another suggested finish. Add it when serving rather than mixing it into the filling.

Storage, Make-Ahead, and Freezing

To make the crisp ahead for the next day, bake it as directed and allow it to cool. Cover the cooled crisp and refrigerate it overnight. When you are ready to reheat it, let it stand at room temperature for about 20 minutes, then place it in a 350°F oven for about 30 minutes, or until hot throughout.

The supplied guidance does not recommend a tested assembled-ahead method before baking. It also does not provide a tested freezing method. Keep those limits in mind when planning the dessert rather than assuming that an unbaked assembled crisp or a frozen portion will behave exactly like the baked and refrigerated version.

Serving Suggestions

Serve the apple crisp warm in individual bowls. Vanilla bean ice cream adds a cold, creamy contrast to the warm fruit and crisp topping, while whipped cream offers a lighter topping option. A drizzle of browned butter salted caramel sauce is another suggested pairing for a richer dessert.

If you have extra browned butter salted caramel sauce, the source also points to caramel apple pie bars, bourbon vanilla ice cream, vanilla chai cheesecake bars, and Butterfinger toffee cookies as other ways to use it.

The crisp is also enjoyable on its own, especially when the topping is golden and the apples are bubbling beneath it. Allowing it to cool slightly before serving makes it easier to spoon while keeping the fruit warm.

Frequently Asked Questions

What apples are best for this apple crisp?

Golden Delicious apples are a favorite for this recipe. Granny Smith and Fuji apples are also suggested, and other apples may be used. Choose the variety you enjoy and cut the apples into chopped pieces or slices.

Do I have to peel the apples?

No. The apples can be peeled or left with their skins on. If you leave the skins on, wash the apples thoroughly before chopping or slicing them.

Can I use quick oats instead of old-fashioned oats?

Yes. Quick oats can be used in the topping, although the finished texture may be slightly different from a topping made with old-fashioned oats.

Why is there juice at the bottom of my apple crisp?

Apples contain water and can release some juice while baking. If you want to reduce the amount of juice at the bottom, the recipe guidance suggests adding a little all-purpose flour to the apple mixture.

How long does apple crisp take to bake?

Bake it at 350°F for 40 to 50 minutes, until the topping is golden brown and the filling is bubbly. Because ovens vary, begin checking the visual cues as you approach the lower end of that range.

How do I reheat apple crisp?

For a crisp baked the day before, let the covered refrigerated dessert sit at room temperature for about 20 minutes. Reheat it at 350°F for about 30 minutes, or until hot throughout.
