Instructions (Step by Step)
1. Prepare the Apple Filling
- Peel, core, and thinly slice the apples.
- Place apples in a large bowl.
- Add:
- Granulated sugar
- Brown sugar
- Cinnamon
- Nutmeg
- Lemon juice
- Flour or cornstarch
- Vanilla extract
- Mix well until apples are evenly coated.
- Fold in raisins if using.
- Set aside for 10–15 minutes so flavors develop.
This resting time helps release juices and improves texture.
2. Prepare the Baking Pan
- Preheat oven to 375°F (190°C).
- Line a 9×13 inch baking pan with parchment paper.
- Lightly butter the parchment.
3. Assemble the Pastry (Two Methods)
Option A: Puff Pastry (Easiest)
- Roll out the puff pastry slightly on a floured surface.
- Place one sheet in the prepared pan.
- Spread apple filling evenly, leaving a 1-inch border.
- Cover with the second pastry sheet.
- Press edges together and seal.
Option B: Phyllo Dough (Traditional Bakery-Style)
- Lay one phyllo sheet in the pan.
- Brush lightly with melted butter.
- Repeat with 8–10 layers.
- Spread apple filling evenly.
- Top with remaining phyllo sheets, buttering each layer.
- Tuck edges inward neatly.
More layers = flakier strudel.
4. Egg Wash & Topping
- Whisk egg and milk together.
- Brush over the top of the pastry.
- Mix sugar and cinnamon.
- Sprinkle evenly over the top.
5. Bake the Strudel
- Bake for 40–50 minutes, until:
- Top is golden brown
- Filling is bubbling
- If browning too fast, cover loosely with foil.
6. Cool & Slice
- Let the strudel cool for 20–30 minutes.
- Slice into squares or rectangles for a bakery-style look.
7. Optional Vanilla Glaze
- Whisk powdered sugar, milk, and vanilla.
- Drizzle over cooled strudel.
