Tips
Use a mix of berries for more complex flavor - the combination of sweet and tart creates better balance than single fruit types.
Toast the oats and nuts until fragrant but not dark to avoid bitter flavors that can overpower the delicate fruit.
Let the dish rest 10 minutes after baking for easier serving and to allow juices to settle into the topping.
Good to Know
Cover and refrigerate up to 3 days. Reheat in 300°F oven for 10 minutes to crisp topping.
Assemble completely and refrigerate up to 1 day before baking. Add 5-10 minutes to baking time if cold.
Best served warm or at room temperature with whipped cream or vanilla ice cream.
Common Mistakes
Don't overbake the oat topping or it will become bitter and hard instead of golden and crispy.
Substitutions
FAQ
Can I use frozen berries instead of fresh?
Yes, but thaw and drain excess liquid first, or increase initial cooking time to evaporate extra moisture and prevent soggy results.
What if I don't have demerara sugar?
Brown sugar works well as substitute. Regular white sugar can be used but will lack the molasses depth of flavor.
How long does this keep and can I freeze it?
Keeps refrigerated 3 days. Can be frozen up to 3 months but texture of topping will soften upon thawing.
