Description
Delicious berry crumble topped with a balsamic glaze, perfect for dessert or breakfast.
Ingredients
- 6 cups (900 g) mixed berries (fresh strawberries, blueberries, raspberries; thaw and drain if frozen)
- 2 tbsp (30 ml) balsamic glaze (store-bought or homemade)
- ½ cup (100 g) sugar
- ¼ cup (30 g) cornstarch
- 2 tbsp (30 ml) lemon juice
- 1 cup (90 g) rolled oats (old-fashioned)
- ½ cup (60 g) chopped or sliced almonds
- ½ cup (60 g) chopped walnuts or pecans
- ½ cup (60 g) all-purpose flour
- 1 tsp (2 g) ground cinnamon
- ¼ tsp (1.5 g) salt
- ½ cup (120 ml) extra virgin olive oil (EVOO)
- 2 tbsp (30 ml) balsamic glaze, for drizzling
Instructions
- Step 1: Preheat Oven: Set your oven to 375°F (190°C) and allow it to heat completely before baking to ensure even cooking and juicy berries.

- Step 2: Prepare Baking Dish: Lightly coat a 9-inch square baking dish with olive oil to prevent sticking and to make serving easier.

- Step 3: Mix Berries & Ingredients: In a large bowl, toss together the mixed berries, 2 tablespoons balsamic glaze, sugar, cornstarch, and lemon juice until the berries are well coated. This mixture forms a sweet and tangy filling.

- Step 4: Make Crumble Topping: In another bowl, combine oats, almonds, walnuts or pecans, flour, cinnamon, and salt. Stir in the olive oil until the mixture achieves a crumbly texture, ensuring a golden and crispy topping.

- Step 5: Assemble & Bake: Spread the berry mixture evenly in the prepared baking dish. Sprinkle the crumble topping evenly over the berries. Bake for 45 to 50 minutes at 375°F (190°C) until the topping is golden brown and berries bubble around the edges. Use visual cues to check doneness. If the topping browns too quickly, cover with foil 25 minutes into baking to prevent burning.

- Step 6: Cool & Drizzle: Remove the crumble from the oven and let it cool for 1 hour at room temperature to allow the filling to set. When ready to serve, drizzle 2 tablespoons of balsamic glaze on top for a finishing touch.

Notes
- Room Temperature: Store the crumble in an airtight container at room temperature up to 2 days away from direct sunlight.
- Refrigeration: Keep the crumble in an airtight container in the refrigerator up to 5 days. Warm slightly before serving to restore texture.
- Freezing: Wrap the cooled crumble tightly with plastic wrap, place in a freezer container, and freeze up to 3 months. Thaw overnight in the refrigerator before reheating.
- If berries release too much juice, add an extra tablespoon of cornstarch to the filling before baking to improve consistency.
- To avoid dry crumble, sprinkle 1 tablespoon of water over the topping 10 minutes before baking finishes for added moisture.
- Adjust the baking dish size when scaling the recipe for fewer servings but keep similar cooking times to maintain even baking.
- Use an oven thermometer to ensure your oven maintains 375°F (190°C) for best results.
- Fresh berries are preferred for optimal flavor and texture, but frozen berries can be used if thawed and drained well.

Ingredient Notes
- Mixed berries: Go for a mix of fresh strawberries, blueberries, and raspberries for a balance of sweetness and tartness. If fresh berries aren’t available, frozen works too, just thaw and drain excess moisture.
- Oats: Use old-fashioned rolled oats for that hearty texture and chewiness. They absorb moisture well, helping the crumble to hold together. Instant oats don’t give the same result, so skip them.
- Brown sugar: I suggest using packed dark brown sugar for a deeper flavor and richness. It adds moisture which helps create that crumbly topping. If you only have light brown sugar, that works, but it’ll be a tad less rich.
- Butter: Opt for unsalted butter for clearer control over the sweetness. This recipe needs cold butter cut into cubes, which helps achieve that crumbly texture. Avoid melting it to get the right consistency!
- Balsamic vinegar: A high-quality balsamic vinegar adds a tangy sweetness. Look for one that’s syrupy for the best glaze. If you need a substitute, try a good red wine vinegar mixed with a little honey.

Recipe Tips
- If the berries release too much juice, add an extra tablespoon of cornstarch to the filling before baking for a better consistency.
- When the topping browns too quickly, cover the crumble with foil 25 minutes into baking to prevent burning.
- If the crumble becomes too dry, sprinkle a tablespoon of water over the topping 10 minutes before finishing to retain moisture.
- When scaling the recipe for fewer servings, adjust the baking dish size and keep the cooking time similar to avoid uneven baking.
- If your balsamic glaze isn’t as thick as desired, simmer on low for 5 extra minutes until it reduces further before drizzling.
Serving Suggestions
Serve berry crumble warm with a scoop of vanilla ice cream or a dollop of Greek yogurt. A side of fresh mint or a simple lemon zest salad also complements the dish well.
Use berry crumble to make parfaits or layer in yogurt cups for breakfast. Add to gluten-free pancakes or mix into smoothie bowls for a fruity twist.
Top with a drizzle of homemade balsamic glaze or a sprinkle of cinnamon. You might also consider adding crushed nuts for extra crunch before serving.
Recipe variations
- You can use any fresh or frozen mixed berries totaling 6 cups to fill the berry crumble, making sure to thaw frozen ones before preparing.
- Add 1 tsp. ground cinnamon along with ½ cup chopped or sliced almonds and ½ cup chopped walnuts or pecans to the topping for added crunch and flavor.
- Either all-purpose flour or a gluten-free substitute can replace the ½ cup flour in the topping to accommodate dietary needs without affecting texture.
- If making extra servings, double the ingredients for a 9×13-inch pan or triple for a larger gathering, adjusting baking time to about 60 minutes for even cooking.
