My Grandma’s Apple Strudel

Makes: 12–16 squares
Bake time: 40–50 minutes
Pan: Jelly roll pan or large baking sheet (about 10×15 inch)

Ingredients

For the Dough

• 4 cups all-purpose flour
• 1 tsp salt
• 1 cup vegetable shortening (or cold butter)
• 2 egg yolks
• ¾–1 cup cold water

Apple Filling

• 8–10 medium apples, peeled and thinly sliced (best: Granny Smith, Honeycrisp, or Braeburn)
• 1 cup sugar
• 2 tsp cinnamon
• 3 tbsp flour
• Optional: pinch of nutmeg or chopped walnuts/pecans

Vanilla Glaze

• 1½ cups powdered sugar
• 2–3 tbsp milk
• 1 tsp vanilla extract

Instructions

1. Preheat the oven
Preheat to 375°F (190°C).

Grease a jelly roll pan lightly.

2. Prepare the apples
In a large bowl, mix:

• sliced apples
• sugar
• cinnamon
• flour

Let sit for 15–20 minutes while preparing the dough.

3. Make the dough
In a bowl, combine flour and salt.

Cut in shortening until crumbly.

Add egg yolks and cold water gradually until a soft dough forms.

Do not overmix.

Divide dough into two equal portions.

4. Roll out the crust
Roll one half into a rectangle large enough for the pan.

Place into the bottom of the pan.

Spread the apple filling evenly over it.

Roll out the second half and place on top.

Seal edges lightly.

5. Vent the crust
Cut several small slits in the top to release steam.

6. Bake
Bake for 40–50 minutes, until:

✅ Golden brown
✅ Apples are tender
✅ Filling is bubbling slightly

7. Add the glaze immediately
Mix powdered sugar, milk, and vanilla.

Spread or drizzle over the strudel while still hot for that classic shiny finish.
