Grandma’s Old-Fashioned Apple Strudel (Bakery-Style Slab Dessert)

Some desserts don’t just satisfy a sweet tooth — they tell a story. Grandma’s Apple Strudel is one of those timeless recipes, the kind that feels like it’s been baked the same way for generations. This is the dessert you’d find cooling on the counter after Sunday dinner, filling the kitchen with the warm aroma of cinnamon and apples while everyone waits (not very patiently) for the first slice.

Unlike delicate, paper-thin phyllo strudels, this old-fashioned version is hearty and generous. It’s baked in a jelly-roll pan and sliced into comforting squares, making it perfect for sharing. The crust is tender and flaky thanks to shortening and egg yolks, creating a nostalgic bakery-style texture that feels substantial without being heavy.

This apple strudel fits beautifully into real life — ideal for holidays, family gatherings, potlucks, or cozy evenings when comfort food is exactly what’s needed. It’s the kind of dessert that quietly disappears as people “just grab one more piece.”

Apple Filling Ingredients

  • 6 cups apples, peeled and thinly sliced

  • 1 cup granulated sugar

  • ½ cup all-purpose flour

  • 1 teaspoon ground cinnamon


Flaky Strudel Crust Ingredients

  • 3¾ cups all-purpose flour

  • 1½ cups shortening

  • 2 egg yolks, plus water to equal 1 cup

  • 1 tablespoon granulated sugar

  • ½ teaspoon salt

  • 1 egg white, reserved (for brushing)


Thin Vanilla Glaze Ingredients

  • 1 cup powdered sugar

  • 2 tablespoons milk or light cream

  • ½ teaspoon vanilla extract


Step-by-Step Instructions

Step 1: Macerate the Apples

In a large bowl, toss the sliced apples with granulated sugar, flour, and cinnamon. Set aside while preparing the dough. This allows the apples to release their juices, which will thicken into a luscious filling as the strudel bakes.


Step 2: Prepare the Dough

In a large bowl, whisk together flour, salt, and sugar. Cut in the shortening until the mixture resembles coarse crumbs.

In a measuring cup, combine the egg yolks with enough water to make 1 cup. Stir this mixture into the flour until a soft dough forms. Divide the dough into two equal portions.


Step 3: Form the Bottom Crust

Roll out one portion of dough into a large rectangle. Press it gently into a greased 10×15-inch jelly-roll pan, fitting it into the corners and slightly up the sides to hold the filling.


Step 4: Fill and Top

Spread the apple mixture evenly over the crust. Roll out the second portion of dough and place it over the apples. Pinch the edges to seal.

Brush the top with the reserved egg white and cut 4–5 small slits to allow steam to escape during baking.


Step 5: Bake

Bake in a preheated 350°F (175°C) oven for 45–60 minutes, until the crust is deep golden brown and apple juices bubble through the vents.


Step 6: Glaze While Hot

Whisk together powdered sugar, milk, and vanilla. Drizzle the glaze over the strudel immediately after removing it from the oven. Allow the strudel to cool completely before slicing into squares.
