This delightful apple oatmeal crisp is a perfect blend of sweet and tart apples with a crunchy oatmeal topping. It's an easy-to-make dessert that brings warmth and comfort, making it an ideal choice for family gatherings or a cozy night in.
Most of the ingredients in this recipe are common pantry staples. However, if you don't usually keep rolled oats or unsalted butter on hand, you might need to pick these up at the supermarket. Rolled oats provide the perfect texture for the crisp topping, while unsalted butter allows you to control the saltiness of the dish.

Ingredients for Apple Oatmeal Crisp Recipe
Apples: Fresh and tart, these are the star of the dish, providing a juicy base for the crisp.
Granulated sugar: Adds sweetness to the apples, balancing their natural tartness.
Ground cinnamon: Infuses the dish with warm, spicy notes that complement the apples.
Rolled oats: These give the topping its signature crunch and texture.
All-purpose flour: Helps bind the topping ingredients together.
Brown sugar: Adds a rich, caramel-like sweetness to the topping.
Unsalted butter: Melts into the topping, creating a deliciously crisp texture.
Technique Tip for This Recipe
To achieve a perfectly crumbly topping for your apple oatmeal crisp, ensure that the butter is fully melted and evenly mixed with the oats, flour, and brown sugar. This will help create a uniform texture that crisps up beautifully in the oven. Additionally, for a more complex flavor, consider adding a pinch of salt to the topping mixture to balance the sweetness.

How to Store or Freeze This Dish
Allow the apple oatmeal crisp to cool completely at room temperature before storing. This helps prevent condensation, which can make the topping soggy.
For short-term storage, cover the baking dish tightly with plastic wrap or aluminum foil. You can also transfer the crisp to an airtight container. Store in the refrigerator for up to 5 days.
To reheat, preheat your oven to 350°F (175°C). Place the apple oatmeal crisp in an oven-safe dish and cover with aluminum foil to prevent the topping from burning. Heat for about 15-20 minutes or until warmed through.
For freezing, first ensure the apple oatmeal crisp is completely cooled. Wrap the entire dish tightly with plastic wrap, followed by a layer of aluminum foil. Alternatively, you can portion the crisp into individual servings and place them in airtight freezer-safe containers or heavy-duty freezer bags.
Label the wrapped or containerized crisp with the date to keep track of its freshness. The apple oatmeal crisp can be frozen for up to 3 months.
When ready to enjoy, thaw the apple oatmeal crisp in the refrigerator overnight. Reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until the topping is crisp and the filling is heated through.
For an extra touch, consider adding a scoop of vanilla ice cream or a dollop of whipped cream when serving the reheated crisp. This can enhance the flavors and provide a delightful contrast in textures.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the apple oatmeal crisp in an oven-safe dish and cover it with aluminum foil. Bake for about 15-20 minutes, or until it's warmed through and the topping is crisp again.
For a quicker option, use the microwave. Place a portion of the apple oatmeal crisp in a microwave-safe bowl. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly. Be cautious not to overheat, as the topping can become soggy.
If you have an air fryer, preheat it to 350°F (175°C). Place the apple oatmeal crisp in the air fryer basket, ensuring it's spread out evenly. Heat for about 5-7 minutes, shaking the basket halfway through to ensure even reheating.
For a stovetop method, place a skillet over medium heat. Add the apple oatmeal crisp and cover with a lid. Heat for about 5-10 minutes, stirring occasionally, until it's warmed through and the topping is slightly crispy.
