The Best Apple Crisp Recipe
When it comes to easy fall desserts, I think it’s safe to say that apple crisp takes the number one spot. It’s similar to apple cobbler, with a layer of spiced apples on the bottom but a crisp topping with oats, instead of the drop biscuits on top. The apple crisp topping is made with oats and just a few other ingredients that are sprinkled over the fruit. Once baked, it adds a rich, crispy surface to the soft and warm baked apples.
This mouth-watering dessert comes together simply by mixing together the apple ingredients then mixing together the topping and layering the two. No need to worry about combining a dough or waiting hours for it to chill. Just mix, dump, and bake!
We love all things apple (and pumpkin too), but this apple dessert ranks very high with our family. It’s also perfect to pull together for those last-minute guests!

How to Make Apple Crisp with Oats
When I say this is one of the easiest desserts to make, I’m being serious! Here’s a brief summary:
(For all the details, scroll below to the complete printable recipe card.)
- Make the apple filling. Toss all of the apple ingredients together to combine, then transfer to a greased baking dish.
- Make the topping. Stir together all topping ingredients. Evenly sprinkle over the apples.

Tips for Success
If this is your first time making apple crisp, here are a few things to keep in mind:
- Old-fashioned oats are a must. Instant or quick oats will not give the desired texture so make sure you use old-fashioned rolled oats in this recipe.
- Slice apples thinly and evenly. For apples that end up perfectly cooked, be sure to slice them to about 1/4″ thick. All slices should be about the same size for even cooking, as well.
- Use aluminum foil to prevent browning. If you notice the topping beginning to brown before the apples are finished, you can cover it with aluminum foil and return it to the oven to finish baking.
- Add pecans or walnuts. For some extra crunch, you can add some chopped nuts like pecans or walnuts to your apple crisp.
This easy apple crisp should be enjoyed warm, fresh from the oven if possible. You can enjoy it on its own or add a big scoop of vanilla ice cream or a dollop of homemade whipped cream. Take it up another notch by drizzling on some caramel sauce for an extra decadent dessert!
How to Store
- Does apple crisp need to be refrigerated? Apple crisp can stay at room temperature for a day but after that, it should be refrigerated. Just pop the pan back in the oven or individual servings in the microwave to heat it back up before serving.
- Can you freeze apple crisp? Yes, you can freeze apple crisp, either before or after baking. You can bake it from frozen or allow it to thaw in the fridge first. Keep in mind that baking it from frozen will require extra time.
