Indulge in a delightful pineapple crisp that is not only delicious but also gluten-free. This easy-to-make dessert combines the tropical sweetness of pineapple with a crunchy oat topping, making it a perfect treat for any occasion.
If you don't usually stock gluten-free oats in your pantry, you might need to pick some up at the supermarket. These oats are essential for ensuring the recipe remains gluten-free. Additionally, fresh pineapple can be substituted with canned pineapple chunks if fresh fruit is not available.

Ingredients For Pineapple Crisp Recipe
Pineapple: Provides the sweet and tangy base for the crisp.
Gluten-free oats: Adds a crunchy texture to the topping while keeping the recipe gluten-free.
Brown sugar: Sweetens the topping and helps it caramelize.
Butter: Binds the topping ingredients together and adds richness.
Cinnamon: Adds warmth and spice to the topping.
Salt: Enhances the flavors of the other ingredients.
Technique Tip for Making Pineapple Crisp
When preparing the pineapple chunks, make sure they are evenly sized to ensure uniform cooking. If using canned pineapple, drain them thoroughly to avoid excess moisture, which can make the crisp soggy. For an extra layer of flavor, consider toasting the gluten-free oats lightly in a dry pan before mixing them with the other ingredients. This will enhance their nutty flavor and add a bit more crunch to the final dish.

How To Store / Freeze This Dessert
Storing in the Refrigerator:
- Allow the pineapple crisp to cool completely at room temperature. This prevents condensation from forming inside the storage container.
- Transfer the pineapple crisp to an airtight container. Alternatively, you can cover the baking dish tightly with plastic wrap or aluminum foil.
- Store in the refrigerator for up to 4 days. The pineapple will stay juicy, and the oat topping will remain slightly crisp.
Freezing for Later:
- Let the pineapple crisp cool completely after baking.
- Transfer the pineapple crisp to a freezer-safe container. If using the original baking dish, cover it tightly with aluminum foil and then wrap it in plastic wrap to prevent freezer burn.
- Label the container with the date and contents. This helps you keep track of how long it has been stored.
- Freeze for up to 3 months. The pineapple will maintain its flavor, and the oat topping will still be delightful after reheating.
Reheating from the Refrigerator:
- Preheat your oven to 350°F (175°C).
- Remove the pineapple crisp from the refrigerator and let it sit at room temperature for about 10 minutes.
- Place the pineapple crisp in the oven and bake for 10-15 minutes, or until heated through. The oat topping should regain its crispiness.
Reheating from Frozen:
- Preheat your oven to 350°F (175°C).
- Remove the pineapple crisp from the freezer and let it thaw in the refrigerator overnight.
- Once thawed, bake the pineapple crisp for 20-25 minutes, or until it is heated through and the oat topping is golden brown and crispy.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover pineapple 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 warmed through. Remove the foil for the last 5 minutes to re-crisp the top.
For a quicker method, use the microwave. Place a portion of the pineapple crisp in a microwave-safe dish. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly. Be cautious as the pineapple can get very hot.
If you have an air fryer, preheat it to 350°F (175°C). Place the pineapple crisp in a small, air fryer-safe dish. Heat for about 5-7 minutes, checking halfway through to ensure the top doesn't burn. This method helps maintain the crispiness of the oat topping.
For a stovetop method, use a non-stick skillet over medium heat. Add a small amount of butter to the pan. Place the pineapple crisp in the skillet and cover with a lid. Heat for about 5-7 minutes, stirring occasionally to ensure even warming. This method can help re-crisp the oat topping while warming the pineapple.
If you prefer a toaster oven, preheat it to 350°F (175°C). Place the pineapple crisp in a toaster oven-safe dish. Cover with aluminum foil and heat for about 10-15 minutes. Remove the foil for the last few minutes to re-crisp the top.
