Breakfast crumble is a warm baked fruit dish topped with a crisp mixture of oats, flour, butter, and a little sweetener. This version uses apples and berries, so it works with fresh or frozen fruit and can be served straight from the oven with yogurt or milk.
Ingredients
- 4 cups (about 500 g) apples, peeled, cored, and cut into ½-inch (1.25 cm) pieces
- 1½ cups (225 g) blueberries or mixed berries, fresh or frozen
- 2 tablespoons (25 g) granulated sugar, for the fruit
- 1 tablespoon (8 g) cornstarch
- 1 tablespoon (15 ml) lemon juice
- ½ teaspoon ground cinnamon, divided
- 1 cup (90 g) old-fashioned rolled oats
- ¾ cup (95 g) all-purpose flour
- ⅓ cup (70 g) packed light brown sugar
- ¼ teaspoon fine salt
- 6 tablespoons (85 g) cold unsalted butter, cut into small cubes
- ¼ cup (30 g) chopped walnuts or pecans, optional
Instructions
- Heat the oven to 375°F (190°C). Lightly butter an 8-inch (20 cm) square baking dish, or use a similarly sized oven-safe dish. Set it on a rimmed baking sheet if you want to catch any fruit juices that bubble over.
- Put the apple pieces and berries in a large bowl. Add the granulated sugar, cornstarch, lemon juice, and ¼ teaspoon of the cinnamon. Toss until the fruit is evenly coated, then tip it into the baking dish and spread it into an even layer. If using frozen berries, add them straight from the freezer rather than thawing; the filling may need a few extra minutes in the oven.
- In a separate bowl, mix the oats, flour, brown sugar, salt, and remaining ¼ teaspoon cinnamon. Add the cold butter. Rub it in with your fingertips or cut it in with a pastry cutter until the mixture forms irregular crumbs, from small flakes to pea-size pieces. Stir in the nuts, if using. Avoid warming the butter with your hands for too long; cooler pieces help the topping bake up crisp rather than greasy.
- Scatter the oat mixture evenly over the fruit without pressing it down. Bake for 35–40 minutes, until the topping is golden and the filling bubbles around the edges. If the top browns before the fruit is bubbling, cover it loosely with foil for the remaining time. If you used frozen berries, allow up to 5–10 extra minutes as needed.
- Let the crumble stand for 10 minutes before serving. The filling will be very hot straight from the oven, and this brief rest also gives its juices time to thicken. Serve warm, or let it cool further for a firmer portion.
Tips
- Choose apples that hold their shape, such as Granny Smith, Honeycrisp, or Braeburn. Softer apples can be used, but the filling will be less distinct and may need a little less sugar if very sweet.
- Measure the fruit after preparing it. The recipe is designed for about 5½ cups (725 g) of fruit; substantially more can crowd the dish and leave the middle watery.
- Keep the butter cold and leave some larger crumbs in the topping. A fine, floury mixture can bake dense, while a few small clumps give the crumble its characteristic crisp texture.
- For a dairy-free version, use a firm plant-based butter alternative in the same amount. Soft tub spreads contain more water and may make the topping less crisp.
Serving Suggestions
Serve the crumble warm in bowls with plain Greek yogurt, thick natural yogurt, or cold milk for a breakfast-style portion. A spoonful of crème fraîche or vanilla ice cream makes it more like dessert. If you prefer a less sweet breakfast, leave off extra sweeteners and pair it with unsweetened yogurt.
The topping is crispest on the day it is baked. For brunch, bake it just before serving or rewarm it uncovered briefly so the top dries and crisps again. The fruit and topping can be prepared separately a few hours ahead; keep the fruit covered in the refrigerator and the topping chilled, then assemble just before baking.
Variations
- Use other fruit: Replace the apples and berries with an equal volume of pears, peaches, plums, or chopped stone fruit. Very juicy fruit may need an extra teaspoon of cornstarch; firmer fruit may need a few more minutes to soften.
- Change the berries: Raspberries, blackberries, or sliced strawberries work well. Frozen fruit is convenient, but avoid thawing it first because thawing releases extra liquid.
- Make it nut-free: Omit the walnuts or pecans. Add 2 tablespoons (20 g) extra oats if you want a little more topping in their place.
- Adjust the spices: Swap the cinnamon for ¼ teaspoon ground ginger or cardamom, or add a pinch of nutmeg. Keep the total amount modest so the fruit remains the main flavor.
- Use whole-wheat flour: Replace up to half the all-purpose flour with whole-wheat flour. The topping will taste nuttier and may be slightly denser; replacing all of it can make the crumbs heavier.
Storage and Reheating
Cool leftovers and refrigerate them in a covered container within 2 hours of baking. The crumble keeps for 3–4 days in the refrigerator. For the best texture, store portions in a shallow container rather than leaving the whole dish uncovered, which can dry out the fruit.
Reheat individual servings in the microwave until hot, or warm the dish in a 325°F (165°C) oven for about 15–20 minutes. Cover loosely with foil if the topping is already dark, then uncover for the last few minutes to refresh its crispness. When reheating leftovers, heat them to 165°F (74°C), the USDA FSIS recommended temperature, checked with a food thermometer. You can freeze cooled portions in a freezer-safe container for up to 2 months; thaw overnight in the refrigerator and reheat as above. The topping may soften after freezing.
Frequently Asked Questions
Can I make breakfast crumble the night before?
Yes. Assemble it, cover the dish, and refrigerate it overnight, then bake it in the morning. Because the dish starts cold, allow roughly 5–10 extra minutes and check that the filling is bubbling. For a crisper topping, keep the topping separate and scatter it over the fruit just before baking.
Can I use frozen fruit?
Yes. Add frozen berries without thawing them, and expect the bake to take a little longer. Frozen fruit can release more liquid, so keep the cornstarch in the recipe and bake until the juices bubble at the edges rather than relying only on the topping’s color.
Why is my crumble topping soggy?
The fruit may have released more juice than the thickener could absorb, or the crumble may have been covered while still warm. Measure the fruit, use the cornstarch, and bake until the filling bubbles. Cool uncovered, then cover and refrigerate once it is no longer steaming.
How do I know when the apples are tender?
The topping should be golden and the fruit juices should bubble around the dish. If you are unsure, carefully insert a thin knife into an apple piece near the center; it should slide in with slight resistance rather than crunching. If the top is already browned, cover loosely with foil and continue baking.
Can I make it without added sugar?
You can omit the 2 tablespoons (25 g) of sugar tossed with the fruit, especially if the fruit is ripe. The brown sugar in the topping provides sweetness and helps it brown; reducing that too will make the topping less crisp and less golden.
Is this crumble suitable for breakfast meal prep?
It can be portioned after baking and refrigerated for a few days. Reheat only the amount you plan to eat, and bring leftovers to 165°F (74°C). The topping will be softer than when freshly baked, but a short uncovered oven reheat helps restore some crispness.
