Easy Apple Crisp with Quick Oats

Fresh-baked apple dessert with apples and cinnamon sticks on a table.

Warm apples, cinnamon and a buttery, crunchy oat topping. This easy apple crisp uses quick oats, so the topping comes together in minutes with no rubbing in cold butter. It’s the perfect way to use up a bag of Ontario apples.

Serves: 6 · Prep: 20 minutes · Bake: 35 to 40 minutes · Pan: 8-inch square baking dish

Ingredients

For the apples

  • 6 medium apples (about 6 cups sliced), peeled and thinly sliced
  • 1/4 cup (50 g) white or brown sugar
  • 1 tablespoon all-purpose flour
  • 1 teaspoon cinnamon
  • 1 tablespoon lemon juice

For the topping

  • 1 cup (90 g) quick oats or plain instant oats
  • 1/2 cup (65 g) all-purpose flour
  • 1/2 cup (100 g) packed brown sugar
  • 1 teaspoon cinnamon
  • A pinch of salt
  • 1/2 cup (115 g) butter, melted

Method

  1. Heat the oven to 375°F (190°C). Lightly grease an 8-inch square baking dish.
  2. Prepare the apples. In a large bowl, toss the sliced apples with the sugar, flour, cinnamon and lemon juice until evenly coated. Spread them in the baking dish.
  3. Make the topping. In the same bowl (no need to wash it), stir together the oats, flour, brown sugar, cinnamon and salt. Pour in the melted butter and stir with a fork until the mixture is crumbly and everything is moistened.
  4. Top and bake. Sprinkle the topping evenly over the apples. Bake for 35 to 40 minutes, until the top is golden and the apple juices are bubbling around the edges.
  5. Cool a little. Let it rest for about 10 minutes so the juices thicken, then serve warm.

Tips

  • Mix your apples. A mix of tart and sweet apples gives the best flavour. Try McIntosh, Northern Spy, Honeycrisp or Gala.
  • Which oats? Quick oats and plain instant oats both work. Skip flavoured instant oatmeal packets, which have added sugar and flavourings. Large-flake oats also work and give a chewier topping.
  • Extra crunchy topping. Add 1/3 cup chopped pecans or walnuts to the topping.
  • Serve it with vanilla ice cream, whipped cream or a spoonful of plain or vanilla yogurt.
  • Leftovers. Cover and keep in the fridge for up to 3 days. Warm single servings in the microwave or in a 350°F oven.

🔄 Easy swaps for this recipe

  • Gluten-free: use oats labelled gluten-free and a gluten-free flour blend.
  • Dairy-free: use a plant-based butter or 1/3 cup vegetable oil.
  • Less sugar: with sweet apples, you can leave the sugar out of the filling.
  • No apples? Use pears, or swap 2 cups of the apples for berries or rhubarb.
  • Whole grain: use whole wheat flour in the topping.
