Tips & Variations
- Add Crunch: Stir in ¼ cup chopped pecans or walnuts to the topping.
- Switch Up the Fruit: Substitute blueberries with peaches, apples, strawberries, or cherries (Note: Apples don’t need cornstarch. Strawberries may need up to 1.5 tsp of cornstarch due to extra moisture).
- Spice It Up: Try a pinch of allspice, nutmeg, or ground cloves for cozy flavor.
- Make it Gluten-Free: Use gluten-free oats and a 1:1 gluten-free flour blend.

Frequently Asked Questions
- Can I make blueberry crisp ahead of time?
Yes! You can assemble the crisp (filling + topping) up to 24 hours in advance and refrigerate it unbaked. When ready to bake, let it sit at room temperature for about 20–30 minutes before putting it in the oven. You can also bake it ahead and reheat it before serving. - Can I use quick oats instead of old-fashioned oats?
You can. The texture will be a little different. Quick oats are finer and will make the topping a bit softer and less crunchy. For the best crisp texture, old-fashioned oats are preferred. - How do I know when berry crisp is done baking?
The topping should be golden brown, and the fruit should be bubbling up around the edges. This usually takes about 40 minutes. Let it cool slightly before serving so the filling can thicken a bit.
How To Store Leftover Fruit Crisp
Refrigerator: Store in an airtight container for up to 4 days. Reheat in the oven or microwave.
Freezer: Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Recipe looks great but I noticed the amount of butter used in the topping is not written in the recipe. Can you tell me what it should be?
