Step-by-Step Instructions
Step 1: Preheat the oven and prepare your dish
Preheat your oven to 180°C / 350°F with a rack in the middle. Lightly butter a 23 cm (9-inch) square baking dish, or a similar 2–2.5 litre (2–2.5 quart) gratin dish. A ceramic or glass dish works beautifully for even baking and a rustic French look.
Set the dish aside while you prepare the apples and streusel. It is helpful to get all ingredients weighed or measured out now so the process feels relaxed and organized.
Step 2: Prepare and season the apples
Peel the apples, then core and slice them into thick slices, about 5–7 mm (1/4 inch). You want them thick enough to hold their shape but not so thick that they stay crunchy.
Place the slices in a large bowl and toss immediately with the lemon juice to prevent browning. Add the granulated sugar, light brown sugar, 1 1/2 tsp cinnamon, nutmeg (if using), cornstarch, vanilla, and 1/4 tsp salt. Toss gently until every slice is lightly coated and no pockets of dry cornstarch remain.
Step 3: Lightly sauté the apples for a bakery-style texture
In a large sauté pan or wide pot, melt the 40 g butter over medium heat. When foaming subsides, add the seasoned apples and any juices from the bowl.
Cook, stirring gently every minute or so, for 5–7 minutes, just until the apples start to soften at the edges and release some juices. They should still be holding their shape and not be fully cooked. This step gives the apples a luxurious, almost compote-like texture once baked, without turning them into mush.
Transfer the apples and all their buttery juices into the prepared baking dish and spread them out into an even layer.
Step 4: Make the French-style streusel topping
In a medium mixing bowl, combine the flour, almond flour, brown sugar, granulated sugar, 1/2 tsp cinnamon, and 1/4 tsp salt. Whisk or stir with a fork to break up any lumps and distribute the ingredients evenly.
Add the cold cubed butter. Using your fingertips, a pastry cutter, or two knives, rub the butter into the dry ingredients until the mixture forms pea-sized clumps and some slightly larger chunks. You are aiming for a mix of sandy crumbs and bigger, irregular pieces. This gives that classic French bakery crumble look with a thick, nubbly, buttery top.
If the kitchen is warm and the butter starts to soften too much, pop the bowl into the fridge for 5–10 minutes to firm back up before topping the apples.
Step 5: Assemble and bake until golden and bubbling
Scatter the streusel evenly over the apples in the baking dish. Do not press it down; you want lots of texture and craggy peaks so it bakes up crisp. Make sure you cover the apples fully, right to the edges, to trap in the steam and juices.
Place the dish on a baking sheet (to catch any drips) and bake in the preheated oven for 35–40 minutes, or until the top is a deep golden brown and you can see the apple juices bubbling thickly around the edges.
If the top is browning too quickly, loosely tent with a piece of foil for the last 5–10 minutes of baking.
Step 6: Let it rest for the perfect texture
Remove the crumble from the oven and place the dish on a wire rack. Allow it to rest for at least 10–15 minutes before serving. This brief cooling time lets the bubbling juices thicken into a silky sauce and makes the portions easier to scoop without falling apart completely.
During this time, the streusel will also crisp up a little more on top as the steam escapes.
Step 7: Prepare the crème fraîche and serve
In a small bowl, whisk the crème fraîche until smooth. Taste it as-is: its natural tang is a beautiful French contrast to the sweet crumble. If you prefer a slightly sweeter, dessert-style topping, stir in 1–2 tsp icing sugar and the vanilla extract until just combined.
To serve, spoon generous scoops of warm apple crumble into shallow bowls or small dessert plates. Add a big dollop of crème fraîche on top or to the side. The gentle melt of the cool, creamy topping over the warm, buttery crumble is what makes this feel truly pâtisserie-worthy.
Pro Tips
- Use a mix of apples. Combining tart apples (like Granny Smith) with sweeter, aromatic ones (like Braeburn or Jonagold) gives a more complex, “French bakery” flavor.
- Keep the butter cold for the streusel. Cold butter creates those crisp, defined crumbs. If it gets too soft, chill the mixture briefly before baking.
- Do not skip the resting time. The crumble will seem very juicy straight from the oven; letting it sit 10–15 minutes thickens the sauce naturally.
- Bake until truly golden. A pale streusel will be soft rather than crisp. Aim for a deep golden brown color on top.
- Serve slightly warm, not piping hot. This makes the flavors more pronounced and keeps the crème fraîche from completely melting away.
Variations
- Pear and apple crumble: Replace half the apples with firm pears. Add a pinch of ground ginger or cardamom along with the cinnamon for a subtle twist.
- Hazelnut streusel: Swap the almond flour for finely ground hazelnuts, and sprinkle a few chopped toasted hazelnuts on top for extra crunch.
- Vanilla custard instead of crème fraîche: For a more traditional French bistro style, serve the warm crumble with chilled vanilla custard or crème anglaise instead of crème fraîche.
Storage & Make-Ahead
Let any leftover crumble cool completely, then cover the dish tightly with foil or transfer portions to airtight containers. Store in the refrigerator for up to 3 days.
To reheat, bake the crumble (uncovered) in a 160°C / 320°F oven for 10–15 minutes, until warmed through and the top is crisp again. Individual portions can be reheated in the microwave, though the topping will be softer. Add a spoonful of fresh crème fraîche just before serving.
For make-ahead prep, you can assemble the streusel topping up to 2 days in advance and keep it chilled in an airtight container. The apples can be sliced and tossed with everything except the cornstarch up to 4 hours ahead (refrigerated); stir in cornstarch just before sautéing and baking.
