Ingredients For Apple Crisp With Oat Topping
Apples: Fresh, peeled, cored, and sliced to provide the base of the crisp.
Lemon juice: Adds a touch of acidity to balance the sweetness of the apples.
Granulated sugar: Sweetens the apple mixture.
Ground cinnamon: Adds warm, spicy notes to the apples.
Gluten-free rolled oats: Forms the crunchy topping while keeping the recipe gluten-free.
Brown sugar: Adds a rich, caramel-like sweetness to the topping.
Gluten-free flour: Helps bind the topping ingredients together.
Butter: Melted to mix with the topping ingredients, adding richness and flavor.
Technique Tip for This Recipe
When preparing the apples, make sure to slice them evenly to ensure uniform cooking. Tossing the apple slices in lemon juice not only adds a hint of tanginess but also prevents them from browning. For the oat topping, use gluten-free rolled oats to maintain the gluten-free integrity of the dish. Mixing the oats with brown sugar, gluten-free flour, and melted butter creates a crumbly texture that will turn golden and crisp in the oven. Bake until the topping is golden brown and the apples are tender, ensuring a perfect balance of textures and flavors.

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, first ensure the apple crisp is completely cooled. Wrap the entire baking dish tightly with plastic wrap, followed by a layer of aluminum foil. Alternatively, you can portion out the apple crisp into individual servings and store in airtight, freezer-safe containers.
Label the containers with the date to keep track of freshness. The apple crisp can be frozen 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 the topping is crisp and the apples are heated through.
For a quicker option, you can microwave individual portions. Place a serving in a microwave-safe dish and cover loosely with a microwave-safe lid or paper towel. Heat on medium power for 1-2 minutes, checking and stirring halfway through, until warmed to your liking.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the apple crisp in an oven-safe dish and cover it with aluminum foil to prevent the oat topping from burning. Bake for about 15-20 minutes or until heated through. This method ensures the apples remain tender and the topping stays crispy.
For a quicker option, use the microwave. Place a portion of the apple crisp in a microwave-safe dish. Heat on medium power for 1-2 minutes, checking halfway through. Be cautious as the sugar can get very hot. This method is convenient but may result in a slightly softer topping.
If you have an air fryer, preheat it to 350°F (175°C). Place the apple crisp in an air fryer-safe dish and heat for about 5-7 minutes. This method helps maintain the crispiness of the oat topping while reheating the apples evenly.
On the stovetop, use a skillet over medium-low heat. Add a small amount of butter to the pan and place the apple crisp in it. Cover with a lid and heat for about 5-7 minutes, stirring occasionally. This method can help revive the oat topping's crunch while warming the apples.
