Commonly Asked Questions
How do I know when the Pineapple Crisp is done baking?
You’ll know it’s ready when the topping is golden brown and the pineapple filling is bubbling around the edges. If you’re unsure, use a toothpick to check the crisp topping—it should feel firm and slightly crispy. If it’s still soft or pale, give it a few extra minutes.
Can I use canned pineapple instead of fresh?
While fresh pineapple gives the crisp a nice, vibrant flavor, canned pineapple will work in a pinch. Just make sure to drain it well to avoid excess liquid that could make the crisp soggy.

Can I add other fruits to the pineapple crisp?
Absolutely! Adding other fruits like mango, peach, or even a handful of berries would work beautifully. Just keep in mind that some fruits may release more moisture, so you might need to adjust the baking time or add a little more topping to balance it out.
How do I store leftovers?
Store any leftover pineapple crisp in an airtight container at room temperature for up to two days. If you want to keep it longer, pop it in the fridge for a few extra days, though it’s best served fresh.
Can I make this ahead of time?
Yes! You can assemble the pineapple crisp and refrigerate it until you’re ready to bake. Just add a few extra minutes to the baking time since it’ll be starting cold. Alternatively, you can bake it ahead of time and store it in the fridge to reheat later.
How do I reheat Pineapple Crisp?
To reheat, simply warm the crisp in the oven at a low temperature, around 300°F, for 10-15 minutes. This will keep the topping crispy while warming the pineapple filling. You can also microwave individual servings for about 30-45 seconds if you’re in a rush.
