Ingredients You’ll Need

For the apple filling:

  • 6 medium apples (Granny Smith, Honeycrisp, or a mix)

  • 1/4 cup granulated sugar

  • 2 tablespoons brown sugar

  • 2 teaspoons ground cinnamon

  • 1 tablespoon lemon juice

  • 2 teaspoons cornstarch (optional, for thickening)

For the oat topping:

  • 1 cup old-fashioned rolled oats

  • 3/4 cup all-purpose flour

  • 1/2 cup brown sugar

  • 1/2 cup unsalted butter (cold, cut into cubes)

  • 1/2 teaspoon salt

  • 1/2 teaspoon ground cinnamon

Step-by-Step Instructions

1. Prep the apples

Peel, core, and slice the apples into thin wedges. Place them in a large bowl and toss with lemon juice, sugars, cinnamon, and cornstarch.

This mixture will help the apples bake into a gooey, flavorful filling.

2. Make the oat topping

In another bowl, combine oats, flour, brown sugar, salt, and cinnamon.

Add the cold butter cubes and use your hands or a pastry cutter to blend until the mixture resembles coarse crumbs.

This is what gives the crisp its crunchy golden topping.

3. Assemble the crisp

Spread the apple mixture evenly into a greased 9×13-inch baking dish.

Sprinkle the oat topping evenly over the apples, making sure to cover them completely.

4. Bake to perfection

Bake at 350°F (175°C) for 40–45 minutes, or until the topping is golden brown and the apple filling is bubbling.

5. Serve and enjoy

Let the apple crisp cool for about 10 minutes before serving.

It’s incredible on its own but takes things up a notch with a scoop of vanilla ice cream or a dollop of whipped cream.

Tips for the Best Apple Crisp with Oats

  • Use a mix of apples: Sweet and tart apples together give the best flavor.

  • Don’t skip the oats: They’re the star of the crunchy topping.

  • Butter matters: Cold butter creates that irresistible crumbly texture.

  • Make it ahead: You can prepare the apple filling and oat topping separately, refrigerate, and then assemble before baking.

Variations to Try

Nutty crunch: Add 1/2 cup of chopped pecans or walnuts to the topping.

Gluten-free: Swap all-purpose flour with almond flour or gluten-free flour blend.

Healthier twist: Use coconut oil instead of butter and cut down on the sugar.

Caramel apple crisp: Drizzle caramel sauce over the apples before adding the topping.
