This delightful apple crisp with oat topping is a perfect dessert for any occasion. The combination of tender, cinnamon-spiced apples and a crunchy, buttery oat topping creates a comforting and delicious treat that is sure to please everyone. Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream for an extra special touch.
While most of the ingredients for this apple crisp are common pantry staples, you may need to ensure you have rolled oats and unsalted butter on hand.

How to Store or Freeze This Dessert
Allow the apple 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. Alternatively, transfer the apple 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 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 a crispier topping, remove the foil during the last 5 minutes of reheating.
For freezing, ensure the apple crisp is completely cooled. Transfer to a freezer-safe container or wrap the entire baking dish tightly with plastic wrap followed by aluminum foil. Label with the date and freeze for up to 3 months.
When ready to enjoy, thaw the apple crisp in the refrigerator overnight. Reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through and the topping is crisp.
To maintain the best texture, avoid microwaving the apple crisp for reheating, as it can make the topping chewy instead of crisp.
If you prefer individual servings, portion the apple crisp into smaller, freezer-safe containers before freezing. This allows for easy, single-serving reheating.
For an extra touch, consider adding a scoop of vanilla ice cream or a dollop of whipped cream when serving your reheated apple crisp.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover apple crisp in an oven-safe dish. Cover it with aluminum foil to prevent the oat topping from burning. Heat for about 15-20 minutes, or until the apples are warmed through and the topping is crisp again. This method helps maintain the original texture and flavor.
Microwave Method: Transfer a portion of the apple crisp to 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 oat topping can become soggy. This method is quick and convenient, perfect for a speedy treat.
Stovetop Method: Place the apple crisp in a skillet over low heat. Cover with a lid and heat for about 5-10 minutes, stirring occasionally to ensure even heating. This method can help retain some of the crispness of the oat topping while warming the apples thoroughly.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the apple crisp in an air fryer-safe dish. Heat for about 5-7 minutes, checking frequently to avoid burning the oat topping. This method can help revive the crispiness of the topping while warming the apples.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the apple crisp in a toaster oven-safe dish. Cover with foil and heat for about 10-15 minutes. This method is great for small portions and helps maintain the texture of the oat topping and the tenderness of the apples.
