-
¾ cup ice water (more if needed)

¼ cup cornstarch
-
1 tablespoon lemon juice

🧑🍳 How to Make Strawberry Slab Pie
1. Make the Crust
In a large bowl, whisk together flour and salt. Cut in cold butter with a pastry cutter or fingertips until mixture resembles coarse crumbs. Slowly add ice water and mix until dough just comes together.
Divide into two discs, wrap in plastic, and chill for 30 minutes (or up to 2 days).
✅ Shortcut: Use two sheets of store-bought pie dough or puff pastry if you’re in a hurry.
2. Prepare the Filling
In a large bowl, toss strawberries with sugar, cornstarch, lemon juice, vanilla, and salt. Let sit for 10 minutes to release juices.
3. Roll Out the Dough
On a lightly floured surface, roll out one dough disc into a rectangle to fit a 10×15-inch sheet pan (with overhang). Press into the pan and trim excess.
Roll out the second disc for the top crust. You can keep it whole, cut it into strips for a lattice, or use cookie cutters for a decorative top.
4. Assemble the Pie
Pour the strawberry mixture into the crust-lined pan and spread evenly. Add the top crust, seal and crimp edges. Cut slits for steam if using a solid top.
Mix egg and milk to make an egg wash. Brush over the crust and sprinkle with coarse sugar.
5. Bake
Preheat oven to 375°F (190°C). Bake for 35–40 minutes, or until the crust is golden and the filling is bubbling.
🔥 Tip: Place a baking sheet under the pan to catch any drips!
6. Cool & Serve
Let the pie cool for at least 1 hour before slicing. This helps the filling set. Serve warm or cold with vanilla ice cream or whipped cream.

❓ Strawberry Slab Pie FAQ
Can I use frozen strawberries?
Fresh is best for texture, but thawed frozen strawberries can work. Just drain excess liquid and increase cornstarch by 1 tablespoon.
Can I make this gluten-free?
Yes! Use a 1:1 gluten-free flour blend for the crust and make sure your cornstarch is certified gluten-free.
What’s the best pan to use?
A 10×15-inch rimmed sheet pan works perfectly. You can also use a 9×13-inch baking dish for slightly thicker slices.
Can I double the filling?
For an ultra-fruity version, increase strawberries to 8 cups and cornstarch to 1/3 cup — just be prepared for a juicier bake.
