Preheat the oven to 350°F. Grease 4 (6-8 ounce) ramekins or a 9” x 9” casserole with butter or nonstick baking spray.
In a large bowl, combine all of the fruit layer ingredients (apples, strawberries, sugar, lemon juice, cornstarch, vanilla extract, and lemon zest). Divide the fruit mixture between the ramekins.
For the Oat Topping
Combine the flour, brown sugar, and oats in a small bowl.
Add the melted butter and mix to combine.
Divide the crumble over the top of each ramekin or evenly over the casserole.
Bake at 350ºF for 20-22 minutes for the individual ramekins, or 40-45 minutes for the casserole. The apple strawberry cobbler is done when the crumble is golden brown and the fruit layer is hot and bubbly.
Allow the crisp to cool slightly before serving (about 10 minutes). Top with fresh whipped cream or vanilla ice cream, if desired.
Notes
For the best flavor, mix tart apples with ripe strawberries. Combining tart fruits like apples or raspberries with sweeter options like strawberries or peaches creates a well-balanced, delicious fruit crisp!
Recipe Variations:
Apple cherry crisp: Use equal parts of apples and cherries in the fruit layer.
Apple blueberry crisp: Swap blueberries for the strawberries in the recipe.
Add some cinnamon or nutmeg to the fruit layer for extra flavor.
Adding chopped pecans, walnuts, almonds, or other nuts will give your oats a bit of a crunch for the topping.
Storing Instructions:
To store fruit crisp, put it in an airtight container and refrigerate for up to three days.
You can also freeze it in a freezer-safe container for up to three months.
