Apple Strudel Recipe Delia Smith: Classic Austrian Pastry With Flaky Layers

There’s something timeless about a properly made strudel, with its paper-thin pastry wrapped around spiced apple filling. This version captures the essence of Austrian baking tradition.

The secret lies in stretching the dough by hand until it’s nearly translucent, creating those signature flaky layers. The apple filling combines tart fruit with cinnamon and raisins for authentic flavor.

Each bite delivers the perfect balance of crisp pastry and tender spiced apples. The technique takes practice but yields classic results worth the effort.

Serve warm with dusting of powdered sugar for the full experience. Here’s everything you need to make this traditional dessert.

Ingredients for Apple Strudel Recipe Delia Smith

Classic Austrian ingredients create paper-thin pastry with spiced apple filling inside.

The flour quality is non-negotiable here. King Arthur or Gold Medal all-purpose delivers the right protein content for stretchable dough. The butter must be European-style (82% fat) for authentic flakiness—Plugrá or Kerrygold are excellent. For the apples, seek out Granny Smith for that essential tartness. Farmers markets often have the best selection in autumn.

No Granny Smith? Braeburn or Jonathan apples work, though they’re slightly sweeter. Swap raisins for dried currants if preferred. The breadcrumbs can be panko pulsed in a food processor to fine crumbs. For a richer filling, add 1/4 cup chopped walnuts (toasted first). If you’re avoiding alcohol in the raisin soak, use apple cider instead of water.

The dough rests 30 minutes at room temperature before stretching—cover it with a damp towel to prevent drying. Assembled strudel keeps 2 days at room temperature (wrapped) or freezes beautifully for 3 months. Dust with powdered sugar just before serving for that bakery-fresh look.

Step-by-Step Instructions for Classic Apple Strudel

This traditional method delivers the signature flaky layers and balanced sweetness you expect from authentic strudel.

Step 1: Prepare the Dough Foundation

In a large mixing bowl, combine the 2 cups all-purpose flour with 0.25 tsp salt. Create a well in the center and add the 1 whole large egg, 0.25 cup lukewarm water, and 2 tablespoons of the 0.5 cup unsalted butter (melted and cooled).

Mix with a wooden spoon until a shaggy dough forms, then turn onto a lightly floured surface. Knead vigorously for 8-10 minutes until the dough becomes smooth and elastic. The texture should be slightly tacky but not sticky—add a dusting of flour if needed.

Cover with a clean kitchen towel and let rest at room temperature for 30 minutes. This relaxation period makes the dough more pliable for stretching later, a critical step for achieving those paper-thin layers characteristic of classic strudel.

Step 2: Create the Spiced Apple Filling

While the dough rests, peel, core, and finely dice the 2 lb tart apples. Toss immediately with 1 tbsp lemon juice and 1 tsp lemon zest to prevent browning. Drain the 0.5 cup raisins if soaked, then combine with the apples in a large bowl.

Add the remaining 0.25 cup granulated sugar (reserving 1 tablespoon for the dough), 1.5 tsp ground cinnamon, 0.5 cup breadcrumbs, and 1 tsp vanilla extract. Stir until the mixture resembles a thick, fragrant compote with no dry spots.

The breadcrumbs absorb excess moisture from the apples, preventing a soggy strudel. The filling should be moist but not wet—this ensures the pastry stays crisp and flaky during baking.

Step 3: Stretch and Assemble the Strudel

Preheat your oven to 375°F. On a clean cotton tablecloth or large sheet of parchment paper dusted with flour, roll out the rested dough as thin as possible. Using the backs of your hands, gently stretch the dough from the center outward until it’s nearly translucent—about 16×20 inches.

Brush the dough lightly with some of the remaining melted unsalted butter, then spread the apple filling evenly over the lower two-thirds, leaving a 2-inch border on all sides. Using the tablecloth to assist, roll the strudel tightly away from you, jelly-roll style, sealing the edges by pinching the dough.

Step 4: Bake to Golden Perfection

Carefully transfer the strudel seam-side down to a parchment-lined baking sheet. Brush the top generously with the remaining melted unsalted butter and sprinkle with the reserved 1 tablespoon granulated sugar for extra caramelization.

Bake for 35-40 minutes until the pastry is deep golden brown and crisp to the touch. The layers should appear distinct and flaky, with the filling just beginning to bubble through the seams. Rotate the pan halfway through for even browning.

Remove from the oven and let cool on the baking sheet for 15 minutes before transferring to a wire rack. This brief rest allows the strudel to set slightly, making it easier to slice cleanly.

Step 5: Finish and Serve

Once cooled to room temperature, dust the strudel generously with 0.25 cup powdered sugar using a fine-mesh sieve. For presentation, make diagonal cuts with a serrated knife, wiping the blade between slices for clean edges.

Serve the strudel slightly warm or at room temperature. Each portion should showcase the delicate, crisp layers encasing the spiced apple and raisin filling, with the powdered sugar providing a delicate finishing touch that complements the flaky pastry perfectly.

Make-Ahead Tips for apple strudel recipe delia smith

Overnight Dough Prep

After kneading, wrap the dough tightly in plastic wrap and refrigerate overnight. This slow fermentation develops 30% more flavor in the pastry. I always do this when baking for brunch gatherings. ❄️

Filling Assembly Ahead

Prepare the apple filling up to 12 hours in advance. Store it in an airtight container in the fridge. The flavors meld beautifully overnight, especially the cinnamon and lemon zest combination.

Pre-Stretched Dough

Stretch the dough paper-thin on parchment, cover with a damp towel, and refrigerate for up to 2 hours. This works when you need to pause mid-assembly. Just bring it to room temp before rolling.

Fully Assembled Strudel

Once assembled but unbaked, strudel keeps well in the fridge for 4 hours. Brush with melted butter just before baking. This timing works perfectly for dinner parties.

Freezing Baked Strudel

Baked strudel freezes beautifully for 3 months wrapped in foil. Thaw at room temperature for 2 hours, then warm at 350°F for 10 minutes to restore crispness. 💡

Powdered Sugar Tip

Dust with powdered sugar only after reheating. If dusted before freezing, it will absorb moisture. A fine-mesh sieve gives the most even, professional-looking coating.
