Apple Crisp with Oat Topping

Old fashioned apple crisp, just like grandma used to make! Perfectly baked spiced apples are topped with a delicious oatmeal crumble topping. Not only is this apple crisp with oat topping delicious served warm with a generous scoop of vanilla ice cream, it makes your house smell amazing in the process!

Apple crisp is THE dessert of fall in our house. It’s so easy to put together, and a great way to use those in-season apples from a trip to the orchard, farmers market, or grocery store. We’ve been makings crisps for years, finally landing on the recipe shared here after years of testing and tweaking and perfecting.

We love this apple crisp recipe with oat topping because it makes enough for a crowd (or enough to have leftovers to enjoy for a few days). It’s a great dessert for fall parties, football Sundays, or for the family with enough leftovers to be warmed up and enjoyed throughout the week.

If you’ve been looking for fun fall treats for a crowd, be sure to try these apple cupcakes, pumpkin bars with cream cheese frosting, pumpkin pie bars, and pumpkin dip too!

What Kind of Oats Should I use for the Oatmeal Crumble Topping?

Old fashioned oats, or rolled oats, are the best option for crumble topping with oats. They provide a wonderful texture and taste to your crumble. 

Quick oats will work if that is what you have in your cabinet, but won’t provide quite as nice of a texture for your oatmeal crumble. 

Steel cut oats and instant oats will not work well and I do not recommend using them for your oatmeal crumble topping.

Helpful Equipment

• Apple Corer, Peeler, Chef’s Knife, and Cutting Board -OR- Apple Peeler Corer Slicer (great option if you do a lot of baking with apples!)
• Large Mixing Bowl
• Medium Mixing Bowl
• Measuring Spoons
• Measuring Cups
• Wooden Spoon
• Pastry Cutter
• 9×13 Baking Dish

How to Make Apple Crisp With Oatmeal

Set oven and prep pan: Preheat oven to 350°F. Grease a 9×13 pan and set aside

Prepare the crisp: In a large mixing bowl, toss the chopped apples with the sugar and spices until evenly coated. Transfer the mixture to the prepared baking dish

Prepare the crumble: In a medium mixing bowl, add all crumb topping ingredients and blend together using a pastry cutter, fork, or your hands. Continue to mix until the mixture creates pea-sized clumps.

Assemble: Spread the crumb topping over the apple mixture and gently pat it into an even layer (make sure to spread your topping into the corners!).

Bake: Bake 45-50 minutes, until the topping is golden brown and the apple mixture is bubbling.

Cool Slightly and Serve: Allow the apple crisp to cool for 15-20 minutes prior to serving. Serve warm, with the option to top with vanilla ice cream and/or caramel drizzle.

Store leftovers: Tightly cover leftover apple crisp and store leftovers in the fridge for up to 5 days. Reheat individual portions of apple crumble with oat topping in the microwave.

Oatmeal Apple Crisp Variations and Substitutions

• Use a mix of sweet and tart apples. Using half sweet and half tart apples in your apple crumble recipe tastes wonderful! Mix and match two of your favorite apples that are good for baking to make the very best apple crisp!
  • Some tart apple favorites are Granny Smith, Braeburn, and McIntosh. 
  • Apples that are both sweet and tart that are great for baking include Pink Ladies and Honeycrisp. 
  • Sweet apples great for baking include Galas and Fuji apples.  
• Change the spice profile. Some apple crisp recipes use cinnamon as the only spice. If that is your preference, replace the pumpkin pie spice with ground cinnamon.
• Add more topping: if you love an extra thick layer of oat crumble on your apple crisp, 1.5x (or even double) the oat topping portion of the recipe. No judgment here! 

Possible Dietary Restrictions?

This apple crisp recipe is vegetarian and egg free as written. One small modification is needed to make this recipe into a gluten-free apple crisp: 

• To make this into a gluten free apple dessert, swap out the all-purpose flour in the oat crumble for a one-to-one gluten free flour alternative. Additionally, if you are serving this to someone with celiac intolerance it is wise to ensure your rolled oats specifically note ‘gluten free’ on the package.
