Lemon Blueberry Crumble Recipe

Flour: The base for the crumble topping, providing structure and texture.

Sugar: Adds sweetness to both the crumble topping and the blueberry filling.

Butter: Cold and cubed, it creates a rich, flaky crumble topping.

Blueberries: The star of the filling, offering a burst of juicy sweetness.

Cornstarch: Thickens the blueberry filling, ensuring it’s not too runny.

Lemon juice: Adds a tangy brightness to the filling, balancing the sweetness.

Lemon zest: Enhances the lemon flavor, providing a fragrant citrus note.

When making the crumble topping, ensure that the butter is very cold and cubed. This helps create a crumbly texture rather than a doughy one. Use a pastry cutter or your fingertips to mix the butter into the flour and sugar until it resembles coarse crumbs. This technique ensures that the crumble will be light and crispy once baked.

• all-purpose flour - Substitute with whole wheat flour: Whole wheat flour adds a nutty flavor and more fiber, making it a healthier option.

• granulated sugar - Substitute with coconut sugar: Coconut sugar has a lower glycemic index and adds a slight caramel flavor.

• unsalted butter - Substitute with coconut oil: Coconut oil provides a dairy-free alternative and adds a subtle coconut flavor.

• fresh or frozen blueberries - Substitute with raspberries: Raspberries offer a tart flavor that complements the sweetness of the crumble.

• granulated sugar - Substitute with honey: Honey is a natural sweetener that adds a unique flavor and moisture.

• cornstarch - Substitute with arrowroot powder: Arrowroot powder is a natural thickener that works similarly to cornstarch.

• freshly squeezed lemon juice - Substitute with lime juice: Lime juice provides a similar acidity and citrus flavor.

• lemon zest - Substitute with orange zest: Orange zest offers a different citrus note that can add a unique twist to the crumble.

• To store your lemon blueberry crumble, allow it to cool completely at room temperature. Once cooled, transfer it to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store in the refrigerator for up to 4 days.

• For longer storage, freezing is an excellent option. First, let the crumble cool completely. Then, wrap the entire baking dish tightly with plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. Alternatively, you can transfer individual portions to airtight freezer-safe containers. The crumble can be frozen for up to 3 months.

• When you're ready to enjoy your frozen lemon blueberry crumble, thaw it in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor of the dessert.

• To reheat, preheat your oven to 350°F (175°C). If reheating the entire dish, remove any plastic wrap and cover it with aluminum foil to prevent the topping from burning. Bake for about 20-25 minutes, or until warmed through. For individual portions, you can use a microwave-safe dish and heat in the microwave for 1-2 minutes, checking and stirring halfway through.

• If you prefer a crispier topping after reheating, uncover the crumble during the last 5 minutes of baking. This will help restore the delightful crunch of the crumble topping.

• Remember, the lemon blueberry crumble is best enjoyed fresh, but these storage and freezing guidelines will ensure you can savor its deliciousness even days or weeks later.

• Preheat your oven to 350°F (175°C). Place the leftover lemon blueberry crumble in an oven-safe dish. Cover it with aluminum foil to prevent the crumble topping from burning. Heat for about 15-20 minutes or until warmed through. This method helps maintain the crispiness of the crumble topping.

• If you're in a hurry, you can use a microwave. Place a portion of the lemon blueberry crumble in a microwave-safe dish. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly. Be cautious as the blueberry filling can become very hot.

• For a quick stovetop method, place a portion of the lemon blueberry crumble in a skillet over medium-low heat. Cover with a lid and heat for about 5-7 minutes, stirring occasionally to ensure even heating. This method can help retain some of the crumble topping texture.

• If you have an air fryer, preheat it to 320°F (160°C). Place the lemon blueberry crumble in an air fryer-safe dish. Heat for about 5-7 minutes, checking frequently to avoid overcooking. This method can help keep the crumble topping crispy.

• For a toaster oven, preheat to 350°F (175°C). Place the lemon blueberry crumble in an oven-safe dish and cover with aluminum foil. Heat for about 10-15 minutes or until warmed through. This method is great for smaller portions and helps maintain the crumble topping texture.

• Oven: Preheat to 350°F (175°C) to bake the crumble until the topping is golden brown and the filling is bubbly.

• Mixing bowl: Use one to combine flour and sugar for the crumble topping, and another to mix the blueberries, sugar, cornstarch, lemon juice, and lemon zest.

• Pastry cutter: Helps to mix the cold, cubed butter into the flour and sugar mixture until it resembles coarse crumbs.

• Baking dish: Pour the blueberry mixture into this dish before sprinkling the crumble topping over it.

• Measuring cups: Measure out the flour, sugar, and blueberries accurately.

• Measuring spoons: Measure the cornstarch, lemon juice, and lemon zest precisely.

• Zester: Use this to zest the lemon for the recipe.

• Juicer: Extract freshly squeezed lemon juice efficiently.

• Spatula: Helps to mix the blueberry filling evenly.

• Cooling rack: Place the baking dish on this after baking to let the crumble cool slightly before serving.

Prepare ingredients in advance: Measure and cube the butter, zest the lemon, and mix the dry ingredients ahead of time to streamline the process.

Use frozen blueberries: If you're short on time, frozen blueberries can be used directly without thawing, saving you the hassle of washing and drying fresh ones.

Pre-mix crumble topping: Combine the flour, sugar, and butter for the topping and store it in the fridge. This way, it's ready to go when you need it.

Utilize a food processor: Quickly pulse the crumble topping ingredients in a food processor to save time on mixing by hand.
