This simple apple crisp is a staple for the fall! Cinnamon-spiced apples topped with an old fashioned oat crumble and baked until the apples are soft and the topping is crisp. It’s easy, SO delicious, and perfect for feeding a crowd.

Is there a more quintessential fall dessert than apple crisp? A warm, casserole-style dessert that’s ideal for holidays, any fall get-togethers, and – since oats are a prominent ingredient here – I’d argue this is an entirely suitable breakfast.
I’ve eaten a lot (a lot!) of apple crisp in my life, and this one has earned its spot as my favorite. Warm cinnamon apples with just a hint of citrus, and the BEST crumble topping that’s so easy to make!

THE APPLE BASE
This recipe uses McIntosh apples. They’re perfect here because they’re not too sweet, and they’ll be just soft enough by the time the oat topping is crisp. If you use Granny Smiths or a similarly hard apple, the topping will be overdone by the time the apples soften.
Once the apples are peeled and diced, they’re tossed with lemon zest and juice, cinnamon, and sugar. It’s a perfect combination of warm cinnamon and refreshing citrus, with just the right amount of sweetness.

THE EASIEST CRUMBLE TOPPING
An ultra-crisp topping of oats, sugar, and butter is what makes apple crisp to me.

Here, all of the ingredients for the crumb topping are tossed into the bowl of a stand mixer (you can also use a hand mixer) and mixed until the butter is crumbled and no dry bits of flour remain.

It is so easy, and turns out perfectly every time. The only way I make crumble toppings anymore!
Once it’s baked and bubbly and the topping is perfectly crisp, serve it warm topped with ice cream.
