How to make strawberry apple crumble
Homemade strawberry apple crumble is so easy to make. Here are easy step-by-step instructions with pictures so any level baker can make this simple recipe.
Step One: First, preheat your oven to 375°F and lightly grease an 8x8-inch baking dish, 9-inch pie dish, or skillet with nonstick cooking spray. Then, set it to the side.
Step Two: Next, toss the strawberries, apples, coconut sugar, lemon juice, lemon zest, vanilla, and starch in a large mixing bowl. Spoon the filling into the greased dish.
Step Three: In a separate bowl, mix together rolled oats, oat flour, walnuts or pecans (optional), coconut sugar, salt, and cinnamon until well combined. Pour maple syrup, melted coconut oil (or butter), and vanilla on top and mix using your hands.
Step Four: Spread the oat crumble mixture evenly on top of the strawberry-apple filling.
Step Five: Bake for 32 – 42 minutes until the top is golden crisp, the strawberries are bubbly, and the apples are tender. I baked mine for about 40 minutes.
Let cool for 10 – 15 minutes before enjoying your delicious apple and strawberry crisp! I love serving mine with vanilla ice cream or frozen yogurt.
Top tips for the best crumble:
- Choose the Right Apples: Use a mix of firm apples like Honey Crisp and Granny Smith for the best flavor and texture. Golden Delicious, Jonathan, or Pink Lady apples also work well.
- Set Oven to 375°F: Baking at 375°F gives a crisp topping and a jammy, not runny, filling. Avoid 350°F to keep the crumble perfect.
- Use Fresh or Frozen Strawberries: Either works! If using frozen, add directly to the bowl—don’t thaw them.
- Customize the Topping: Add chopped nuts (almonds, pecans, or walnuts) for crunch, or season with cinnamon, nutmeg, or a pinch of salt for extra flavor.
- Nut-Free Option: Skip the nuts if you have an allergy.
- Double the Recipe: For a crowd, double the recipe and bake in a 9x13” dish.
- Don’t Skip the Starch: Adding cornstarch, arrowroot, or tapioca starch helps thicken the filling so it’s not too watery. It’s key for that perfect jammy texture!
Easy ingredient substitutions
Here are some simple swaps for the strawberry apple crumble. Just try to replace only one or two to keep the recipe close to the original!
- Strawberries: Use frozen strawberries (don’t thaw), or swap with peaches, blackberries, blueberries, or mixed berries.
- Apples: If you don’t have Granny Smith or Honey Crisp, try Golden Delicious, Jonathan, or Jonagold.
- Pecans: Swap with almonds or walnuts, or skip them for a nut-free option.
- Coconut Oil: Use melted unsalted butter or vegan butter. If using salted butter, skip the added salt in the topping.
- Oat Flour: Substitute with almond flour.
- Coconut Sugar: Use light or dark brown sugar instead.
- Cornstarch: Swap with tapioca flour or arrowroot powder.
- Maple Syrup: Replace with honey or agave syrup.
