Ingredients

Filling

  • 7-8 apples peeled, cored, and cut into chunks
  • 2 Tablespoons granulated sugar
  • 2 Tablespoons all-purpose flour
  • 1 Tablespoon lemon juice
  • 1/2 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon

Streusel

  • 1 cup all-purpose flour (125g)
  • 1 cup rolled oats
  • 1 cup brown sugar
  • 1 teaspoon ground cinnamon
  • 3/4 cup salted butter

Instructions

  • Preheat the oven to 375°F.
  • Add apples, sugar, flour, lemon juice, vanilla, and cinnamon to a 9x13-inch pan. Toss to coat the apples evenly.
    7-8 apples, 2 Tablespoons granulated sugar, 2 Tablespoons all-purpose flour, 1 Tablespoon lemon juice, 1/2 teaspoon vanilla extract, 1 teaspoon ground cinnamon
  • In a large bowl, combine the remaining flour, oats, brown sugar, cinnamon and butter using a pastry cutter to cut the softened butter into the other ingredients until they resemble coarse crumbs. Sprinkle over the apple layer.
    1 cup all-purpose flour, 1 cup rolled oats, 1 cup brown sugar, 1 teaspoon ground cinnamon, 3/4 cup salted butter
  • Bake for 35-40 minutes until the apples are tender and the crisp topping is a nice golden brown.

Notes

Storage: 
You can store this apple crisp in an airtight container at room temperature for 3-4 days covered with plastic wrap or up to 1 week in the fridge.
You can freeze leftover apple crisp for up to 2 months! Thaw and reheat either in a warm oven, the microwave, or the air fryer (my preferred method because it will crisp up that topping much better than the other two).
It's also a wonderful dessert to make in advance for any party or crowd since it is easy to reheat in the oven or also delicious served room temperature.
Tips: 
  • Our favorite way to serve apple crisp. We like to serve it still warm with a big scoop of vanilla ice cream and caramel sauce drizzled on top for the best fall dessert of all time!
  • Prep the fruit. Start with your fruit filling by peeling, coring, and slicing a bunch of apples! This part takes the longest, but if you enlist some helpers it's not too bad. And the apple peels make a fun snack while you wait for the apple crisp to bake.
  • Slice the apples to an even thickness so they bake evenly in the oven. If you slice some really thin and leave others chunky, you won't have as consistent results with your apple crisp.
  • Make it in an 8x8-inch baking dish. You can easily cut this recipe in half, but we always make the full thing because everybody always wants second helpings. And if I'm being honest, it's pretty delicious for breakfast the next day.
  • If you want to omit the oats, no problem. We suggest adding in chopped nuts like walnuts or pecans to add more texture to the topping, plus additional flour depending on the ratio of ingredients.
