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. 

This apple crisp recipe with oat topping is my go-to apple crisp recipe. It makes enough for a crowd (or enough to have leftovers to enjoy for a few days). Apple crisp is great for fall parties, football Sundays, or as a treat for the family with leftovers warmed up and enjoyed throughout the week.

What’s the Difference Between Apple Crisp, Apple Crumble, and Apple Cobbler?

Have you always wondered what the difference between a crisp, a crumble, and a cobbler is? While none have a bottom layer, and have similar fillings, the difference lies in the topping.

Crisps have oats and sometimes nuts in the topping. Crumbles have a similar streusel style topping to a crisp but leave out the oats. Cobblers have a pie-dough or biscuit dough topping.

Why You’ll Love This Apple Crisp with Oatmeal Crumble Topping

Level of difficulty: Easy. The most time-consuming part of this recipe is peeling and chopping the apples, otherwise it’s a little tossing, a little mixing, layering in your pan and baking.

Flavor: Apples and warm fall spices.

Time: It will take you approximately 1 hour to prep and bake your apple crisp with oat topping. The prep time may vary shorter or longer than noted depending on how quickly you can peel and chop your apples.

Step-By-Step Instructions

1. Set oven and prep pan: Preheat oven to 350°F. Grease a 9×13 pan and set aside
2. 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
3. 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.
4. 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!).
5. Bake: Bake 45-50 minutes, until the topping is golden brown and the apple mixture is bubbling.
6. 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.
7. 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.

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.

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.

How to Serve Apple Crisp with Oat Topping

Apple crisp can be served warm or cold based on personal preference. Serving apple crisp warm is the most common way to enjoy this delicious fall dessert.

Serving apple crisp with oat crumble topping with a scoop of vanilla ice cream on top is a classic and delicious addition! Take it one step further with a drizzle of caramel sauce or salted caramel sauce.

Storage & Reheating

Store cooked and fully cooled apple crisp covered in the fridge for up to 5 days.

When ready to enjoy, scoop your serving into a bowl and heat in the microwave in 30 second increments until the desired temperature is reached. Top with ice cream and caramel sauce if desired and enjoy!
