Ingredients

For the Fruit Filling:

• 4 cups fresh or frozen peaches, sliced or diced
• 2 cups fresh or frozen raspberries
• 1/2 cup granulated sugar (adjust based on fruit sweetness)
• 2 tablespoons all-purpose flour or cornstarch (for thickening)
• 1 teaspoon vanilla extract
• 1 tablespoon fresh lemon juice

For the Crumble Topping:

• 1 1/2 cups all-purpose flour
• 1 cup packed light brown sugar
• 1/2 cup rolled oats (not instant)
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1 stick (1/2 cup) cold unsalted butter, cut into small cubes

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish or a 9-inch pie plate.
2. Prepare the fruit filling: In a large bowl, gently toss the peaches and raspberries with the granulated sugar, flour (or cornstarch), vanilla extract, and lemon juice until all the fruit is evenly coated. Pour the mixture into the prepared baking dish and spread into an even layer.
3. Prepare the crumble topping: In a separate medium bowl, whisk together the flour, brown sugar, rolled oats, cinnamon, and salt.
4. Cut in the butter: Add the cold, cubed butter to the dry topping ingredients. Use your fingertips, a pastry blender, or two knives to cut the butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Do not overmix; having distinct butter pieces helps achieve a crispier topping.
5. Assemble: Evenly sprinkle the crumble topping over the fruit filling, ensuring the fruit is mostly covered.
6. Bake: Place the dish on a baking sheet (to catch any potential bubbling over) and bake for 40 to 50 minutes, or until the topping is golden brown and the fruit filling is bubbling thickly around the edges.
7. Cool: Let the crumble cool on a wire rack for at least 15 to 20 minutes before serving. This allows the filling to set slightly.

Expert Tips / Pro Tips

For the absolute best Easy Raspberry Peach Crumble experience, keep these tips in mind:

• Use Cold Butter: This is the golden rule for any crumble or crisp topping. Cold butter creates steam pockets while baking, resulting in those desirable flaky, crunchy clusters.
• Thickening Agent Check: If you are using very juicy frozen fruit, consider increasing the flour or cornstarch in the filling to 3 tablespoons to ensure the juices thicken properly into a luscious sauce rather than a runny liquid.
• Prevent Burning: If the topping starts browning too quickly before the fruit is caramelized, loosely tent the dish with aluminum foil for the remainder of the baking time.
• Toasting the Oats: For an extra nutty flavor in the topping, quickly toast the rolled oats in a dry skillet over medium heat for 3-5 minutes until fragrant before adding them to the rest of the dry ingredients.

Variations & Substitutions

This recipe is highly adaptable based on what fruit you have on hand or what flavors you prefer:

• Fruit Swap: This recipe works beautifully with blueberries, blackberries, cherries, or even chopped apples mixed with the peaches. Maintain the same volume (6 cups total fruit).
• Nutty Topping: Add 1/2 cup of chopped pecans or slivered almonds to the crumble topping for an added crunch and deeper flavor profile.
• Spice It Up: Substitute the cinnamon with 1/4 teaspoon nutmeg and 1/4 teaspoon ground cardamom for a more sophisticated spice blend.
• Gluten-Free Option: Substitute the all-purpose flour in both the filling (if needed) and the topping with a good quality 1-to-1 gluten-free baking blend.

Serving Suggestions

The best way to enjoy this warm dessert is slightly cooled, allowing the filling to set just enough to hold its shape when scooped.

• Classic Pairing: Serve warm slices topped with a generous scoop of high-quality vanilla bean ice cream that melts appealingly over the crumble.
• Elegant Finish: Dollop with fresh homemade whipped cream sprinkled lightly with a touch of cinnamon or lemon zest.
• For Breakfast: Leftover crumble is decadent served cold or reheated with a drizzle of plain Greek yogurt the next morning.

Storage, Freezing & Reheating

Storing leftovers correctly ensures this crumble tastes great for days.

• Storage: Once completely cooled, cover the baking dish tightly with plastic wrap or transfer any leftovers to an airtight container. Store at room temperature for up to 2 days, or in the refrigerator for up to 5 days.
• Freezing Unbaked: You can assemble the unbaked crumble completely, cover it tightly with plastic wrap and then foil, and freeze it for up to 3 months. Thaw overnight in the refrigerator before baking as directed, adding about 10-15 minutes to the bake time.
• Reheating: To reheat individual servings, microwave for 45 to 60 seconds. To reheat the entire dish, cover loosely with foil and bake at 350°F (175°C) for about 15 minutes until warmed through.

FAQ

Can I use frozen fruit in this recipe without thawing it first?

Yes, you can absolutely use frozen peaches and raspberries directly from the freezer. If you use frozen fruit, you may need to increase the baking time by 5 to 10 minutes, or until you see active bubbling throughout the filling.

Why is my crumble topping runny or soggy?

Soggy topping is usually caused by one of two things: either the butter was not cold enough, or the topping was mixed too much, developing the gluten in the flour too soon. Ensure your butter is rock solid and try to work the topping mixture quickly, aiming for distinct, coarse crumbs.

What is the best baking dish size for this amount of fruit?

An 8×8 inch square baking dish or a 9-inch round pie dish works perfectly. If you use a dish that is significantly larger (like a 9×13 inch), the fruit layer will be too thin, and the crumble will cook much faster.
