Ingredients and substitutions
- Oat flour: You can make your own oat flour by grinding oats in a blender until a fine powder has formed.
- Oats: Make sure to use rolled oats, not steel-cut oats or quick-cooking oats.
- Walnuts: If you want to make this recipe nut-free, you can use sunflower seeds instead. Or feel free to use any nuts you like such as pecans or almonds.
- Pepitas: If you're not a fan, you can use another nut/seed of choice instead.
- Cinnamon: Brings warmth and flavors the crisp. If you want to level it up, use pumpkin pie spice or apple pie spice instead!
How to make healthy apple crisp
Prepare the apples. Core, peel, and cut them into small pieces. Add to a baking dish and toss with cinnamon, sugar, and lemon juice.
To make the oat topping, add all of the ingredients to a bowl and mix well. It's best to use your hands or a fork.
To assemble them together, cover the apples with the oat topping and bake for 35 minutes, or until the top is golden and the apples are bubbly.
- Peel the apples for a smoother consistency. If you don't mind apple skin, you can leave it in, but I personally prefer to remove it.
- Allow time to cool. The crisp will continue to set as it cools and it will be easier to scoop and serve.
- Cut the apples into small pieces. This ensures that your apples will cook through and be soft by the time the topping has browned.
- Use gluten-free certified oats to ensure that your crisp is gluten-free.
- Use solid, but scoopable coconut oil. It makes for a better texture of the oat topping and ensures that it will be light and crumbly.
Apple crisp is almost always made with an oat-nut topping, while apple crumble is made with just plain flour. There are different variations though and in some countries, they mean the same thing.
Not enough fat and/or sugar can cause that. If your topping appears dry and way too crumbly, add a bit more coconut oil, one tablespoon at a time. And for the sugar, we suggest not going below ¼ cup.
It's best to use a combination of honey crisp and granny smith. However, if you want a sweeter apple crisp, use all honey crisp apples. If you want more of a tangier taste, use all granny smith.
Yes, you can assemble the crisp the night before, wrap it in foil, and bake the next day.
Yes. Let the crisp cool completely then cover it with a double layer of foil (either plastic or aluminum), and freeze for 3 months. Let it thaw overnight before reheating.
Apple crisp can lose its crispiness as it cools, so we always suggest reheating it in the oven for best results, although the microwave can work as well.
- Oven: Preheat your oven to 350°F (180°C). Place leftovers in a baking tray and optionally spray coconut oil over the topping. Cover with aluminum foil and cook for 10 to 15 minutes. To crisp the topping, remove the foil for the last 3 to 5 minutes of cooking.
- Microwave: Add crisp to a microwave-safe plate and cook for 1-2 minutes or until warmed through.
