  • Apples – there are so many varieties of apples that would be delicious in this recipe. I used Honey Crisp apples as they are our favourite apples for snacking on and they held up beautifully in this apple crisp. You can also use Cortland, Empire and Gala apples. I would recommend staying away from McIntosh apples or Red Delicious as they can get mushy.
  • Rolled Oats – use old-fashioned oats for this recipe. In a pinch, you could substitute quick oats.
  • Pecan or Walnuts – adding in toasted pecans or walnuts to the topping is optional. They add another layer or flavour and crunch to the texture. You can chopped them a little or leave them whole.
  • Butter – cold butter is used for the topping. Chop it into cubes to make it easier to blend for the topping.

How do you make apple crispy from scratch?

If you’re using walnuts or pecans in the topping, toast them in the oven on a baking sheet in a 350°F oven for 4 to 5 minutes until lightly browned. Set aside.

Melt the butter in a 12-inch cast iron skillet. Next, whisk in the brown sugar, cinnamon and salt.

Gently, stir in the apples and cook over low-medium heat for seven minutes, stirring occasionally. The mixture should be bubbling as it cooks.

By now, your kitchen will smell absolutely delicious!

Cut in the cold butter by hand or using a pastry blender.

Apple Crisp can be covered and refrigerated for up to three days.

Although you can freeze an apple crisp, I would recommend baking it in an 8×8-inch baking pan if you plan on freezing it. Simply cover the container with plastic wrap, then foil and freeze for two to three months.



What is a good apple to make apple crisp with?

Cortland, Empire, Granny Smith and Honey Crisp apples will all hold their shape and cook beautifully.

Can I leave apple crisp out overnight?

Apple Crisp is best stored covered in the refrigerator. If you want to warm it up, you can put it into the microwave or warm up in a low oven at 350°F for about 15 minutes.
