Ingredients You’ll Need

Apples

• 6 medium apples, about 2 to 2½ pounds
  • Use a mix of tart and sweet: Granny Smith + Honeycrisp or Fuji work great.
  • Peel the apples if you like a softer texture, or leave the peel on for more fiber and a rustic feel.

Apple Filling

• 1/3 cup granulated sugar
• 2 tablespoons brown sugar, light or dark
• 1½ teaspoons ground cinnamon
• 1/4 teaspoon ground nutmeg (optional but tasty)
• 1/8 teaspoon ground cloves or allspice (optional, use lightly)
• 2 tablespoons all-purpose flour or 1 tablespoon cornstarch
• 1 tablespoon lemon juice (bottled works fine)
• 1 teaspoon vanilla extract
• Pinch of salt

Oat Crisp Topping

• 3/4 cup old-fashioned rolled oats
  • Use old-fashioned oats, not instant or quick oats, for the best texture.
• 3/4 cup all-purpose flour
• 1/2 cup packed brown sugar
• 1/4 cup granulated sugar
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1/2 cup cold unsalted butter, cut into small cubes
  • Use salted butter if that is what you keep on hand and slightly reduce the added salt.
• Optional add-ins:
  • 1/2 cup chopped pecans or walnuts
  • 1/4 cup shredded coconut for extra chew

Pantry Shortcuts & Substitutions

• Use pre-sliced bagged apples from the produce section when you feel short on time.
• Swap gluten-free all-purpose flour for regular flour to make a gluten-free apple crisp with oats.
• Use coconut oil instead of butter for a dairy-free version, and add a tiny pinch more salt for flavor.
• Use pumpkin pie spice instead of separate spices if that already sits in your pantry.

Equipment

• 8×8 inch baking dish or similar size (2-quart)
• Large mixing bowl
• Medium mixing bowl
• Cutting board and sharp knife
• Measuring cups and spoons
• Fork or pastry cutter
• Spoon or spatula

Tips & Tricks

• Slice apples into even 1/4 to 1/2 inch slices so they cook at the same rate.
• Toss apples with lemon juice right away so they keep their color and brightness.
• Chill the topping while you prep the apples so the butter stays cold and bakes up crisp.
• Use cold butter and work it into the topping until you see pea-sized bits for the best crumbly texture.
• Pack the topping lightly over the apples and cover the surface so no apples dry out.
• Bake on a sheet pan if your dish sits very full, so any bubbling juices land on the pan instead of your oven.
• If the topping browns too fast, tent the dish loosely with foil and keep baking until the apples soften.
• Let the crisp rest at least 10 to 15 minutes so the juices thicken and the slices hold together.

How to Make Apple Crisp Recipe With Oats

Step 1: Prep the apples

Preheat your oven to 350°F and grease your baking dish with butter or nonstick spray. Peel the apples if you prefer, then core and slice them into thin wedges about 1/4 to 1/2 inch thick. Place the apple slices in a large mixing bowl.

Drizzle the lemon juice over the apples and toss to coat. This step keeps the apples bright and adds a little tang that balances the sweetness.

Step 2: Mix the apple filling

Add the granulated sugar, brown sugar, cinnamon, nutmeg, cloves or allspice if using, flour or cornstarch, vanilla, and a pinch of salt to the apples. Toss everything together until the apples look evenly coated and no dry pockets of flour remain. The mixture should look glossy and slightly sticky.

Pour the apple mixture into the greased baking dish and spread it into an even layer. Press the apples down lightly so they sit snugly in the dish.

Step 3: Make the oat topping

In a separate bowl, add the oats, flour, brown sugar, granulated sugar, cinnamon, and salt. Stir until everything mixes evenly and no clumps of sugar remain. Add the cold butter cubes to the bowl.

Use a fork, pastry cutter, or your fingertips to work the butter into the dry ingredients. Stop when the mixture looks crumbly with pea-sized bits of butter throughout. Stir in nuts or coconut if you use them.

Step 4: Top the apples

Sprinkle the oat mixture evenly over the apples. Cover the entire surface so the apples sit under a blanket of topping. Gently press the topping down so it sticks together but still looks craggy and textured.

If your dish looks very full, slide it onto a rimmed baking sheet to catch any bubbling juices. That small step saves you from scrubbing the oven later.

Step 5: Bake

Place the dish in the preheated oven and bake for 35 to 45 minutes. Check at 30 minutes and keep an eye on the color of the topping. The apple crisp finishes baking when the top looks golden brown and the juices bubble around the edges.

If the topping browns too quickly, cover the dish loosely with foil and keep baking until the apples feel tender when you poke them with a knife. Total time can vary a bit based on how thick you sliced the apples and how full the dish sits.

Step 6: Cool slightly and serve

Remove the apple crisp from the oven and place it on a cooling rack or trivet. Let it rest for at least 10 to 15 minutes so the juices thicken and the topping sets. This short wait time also keeps the hot sugar from burning your tongue.

Serve warm with a scoop of vanilla ice cream, whipped cream, or a drizzle of heavy cream. Enjoy the contrast of warm apples and cool topping while everything still tastes fresh and fragrant.

What to Serve with Apple Crisp Recipe With Oats

Serve this apple crisp recipe with oats warm with vanilla ice cream for a classic combo that never disappoints. Add a spoonful of whipped cream or a drizzle of caramel sauce when you want a richer dessert. Pair it with hot coffee, chai, or a mug of hot chocolate for a cozy treat.

You can also serve it at brunch with plain Greek yogurt to balance the sweetness and add some protein. Kids usually love it with a glass of cold milk and a sprinkle of extra cinnamon on top.

Storage Options

• Store leftover apple crisp covered in the fridge for up to 4 days.
• Keep it in an airtight container to prevent the topping from picking up fridge odors.
• Freeze baked apple crisp tightly wrapped for up to 2 months, then thaw overnight in the fridge.
• Reheat single servings in the microwave in 20 to 30 second bursts, or use a 350°F oven for 10 to 15 minutes so the topping turns crisp again.
• Add a tiny splash of water or apple juice to the dish before reheating if the filling looks dry.
