This easy apple strudel recipe wraps soft grated apples, walnuts, brown sugar, and cinnamon inside crisp layers of buttery filo pastry. Cooking and thickening the apple filling before rolling makes it easier to handle, while ready-made filo removes the work of preparing homemade dough.

Why You'll Love This Apple Strudel

Crisp, Buttery Layers: Brushing the filo sheets with melted butter helps them bake until golden and crisp.
Soft Grated Apple Filling: Grating the apples allows them to soften evenly and creates a filling that sits neatly inside the pastry.
Walnuts Between Every Layer: The walnut and cinnamon mixture adds a delicate crunch throughout the strudel.
Made for Sharing: One batch makes four strudels that are cut into 16 individual pieces before baking.

The first time I baked this apple strudel, I could not believe how ready-made filo could create such delicate, crisp layers around the soft apples. It feels quite different from my apple loaf cake, where the fruit bakes into a tender crumb, or my apple crisp with oat topping, which has a thicker, more rustic topping. This strudel has a lighter texture, and cutting each roll into individual pieces makes it especially easy to share.

What keeps me coming back to this easy apple strudel recipe is the contrast between the soft filling, crisp pastry, and finely chopped walnuts. Grating and cooking the apples first creates a smooth filling, while the cornstarch thickens the juices before the apples reach the filo. The result is different from my easy apple fritters, which have a soft fried center, and my homemade applesauce, where the apples are cooked down completely.

Key Ingredients in Easy Apple Strudel

Here are the four ingredient groups that give this strudel its distinctive texture and flavor.

Apples: I prefer Granny Smith apples because their tartness balances the brown sugar. Grating them helps the filling soften evenly.
Filo Pastry: Ready-made filo pastry, also called phyllo dough, creates the thin, crisp layers without making and stretching dough from scratch.
Walnuts, Brown Sugar and Cinnamon: I sprinkle this finely chopped mixture between the filo sheets, adding gentle sweetness, warmth and crunch throughout each roll.
Butter: Brushing the sheets lightly with melted butter separates the delicate layers and helps the pastry turn golden in the oven.

How to Make Easy Apple Strudel

The apples need time to cook and cool, but the assembly is straightforward once the filling is ready. You can find the complete printable Easy Apple Strudel recipe with measurements below.

1. Prepare the Apple Filling: Peel, core, and grate the apples. Cook with brown sugar until soft and caramelized, then stir in cornstarch mixed with water. Let cool.

2. Make the Walnut Mixture: Finely chop walnuts, then mix with brown sugar and cinnamon.

3. Layer and Roll the Filo: Layer three sheets of filo pastry with butter and walnut mixture. Add apple filling along one edge, roll tightly, and place on a tray. Repeat to make four strudels.

4. Cut and Bake: Cut each apple strudel into pieces, brush with butter, and bake at 350°F / 180°C for 40-45 minutes until golden and crisp.

Tips for Easy Apple Strudel

Chop the Walnuts Finely: I keep the walnut pieces small so they spread evenly between the thin filo layers without making the pastry difficult to roll.

Brush the Butter Lightly: A thin, even layer is enough for each sheet. Avoid letting the butter collect in heavy patches.

Do Not Overfill: Using the right amount of apple filling helps each strudel hold its shape and reduces the chance of splitting while it bakes.

Look for a Golden Finish: I use the baking time as a guide, but I also check that the filo has turned evenly golden and crisp before removing the strudel.

Storage

I keep leftover apple strudel in an airtight container for one or two days. When I want to bring back the crisp texture, I reheat the pieces in the oven rather than the microwave.
