Easy Rustic Strawberry Blueberry Slab Pie Recipe with Star Lattice Perfect for Summer

“Hey, you gotta try this pie,” my neighbor called over the fence one sunny afternoon. I was in the middle of a chaotic yard cleanup, and honestly, I wasn’t expecting much from a quick, “easy slab pie” she whipped up with whatever berries she had on hand. But when that rustic strawberry blueberry slab pie with its charming star lattice came out of the oven, I was hooked. The flaky crust, the burst of fresh berries, and that unexpected star pattern on top—it felt like summer on a plate, simple and unpretentious.

What’s funny is that pie wasn’t meant to be fancy. It started as a last-minute plan when the usual pie pan was nowhere to be found. Instead, she baked it on a baking sheet, turning the whole thing into a casual, shareable dessert that fit perfectly with our impromptu neighborhood get-together. The star lattice wasn’t just decoration—it brought a little whimsy to an otherwise straightforward recipe.

That afternoon, with sunlight filtering through the leaves and a cold glass of lemonade nearby, the pie became a quiet highlight. It wasn’t about perfection but about good taste, easy sharing, and those summer berries that feel like a fleeting gift. I’ve made it countless times since—sometimes swapping in whatever fruit is ripe or pairing it with whipped cream—and it never fails to bring a little calm to the chaos. This easy rustic strawberry blueberry slab pie with star lattice is one of those recipes that sticks with you, for its simplicity and the little moments it creates.

What Ingredients You Will Need

This easy rustic strawberry blueberry slab pie with star lattice uses straightforward, wholesome ingredients that come together quickly but deliver big on flavor. Most of these are pantry staples, and the berries can be fresh or frozen depending on the season.

• For the crust:
  • 2 ½ cups (315g) all-purpose flour, plus extra for dusting
  • 1 cup (227g) unsalted butter, cold and cubed (I prefer using Plugrá for a flaky crust)
  • ¼ cup (50g) granulated sugar
  • 1 teaspoon salt
  • 6-8 tablespoons (90-120ml) ice-cold water
• For the filling:
  • 3 cups (450g) fresh strawberries, hulled and quartered (frozen works too, just thaw and drain)
  • 3 cups (450g) fresh blueberries
  • ¾ cup (150g) granulated sugar (adjust based on berry sweetness)
  • 3 tablespoons (24g) cornstarch (helps thicken the juicy filling)
  • 1 teaspoon lemon zest (brightens the berry flavor)
  • 1 tablespoon fresh lemon juice
  • ½ teaspoon ground cinnamon (optional, adds warmth)
  • 1 teaspoon vanilla extract
• For the topping:
  • 1 large egg, beaten (for egg wash)
  • 2 tablespoons coarse sugar (like turbinado) for sprinkling

These ingredients work together to create a perfect balance of sweet, tart, and buttery. If you want a gluten-free option, almond flour crusts can work well, though the texture will be different. For dairy-free, swap butter with coconut oil or vegan butter alternatives. And if you’re in the mood to mix berries, blackberries or raspberries can join the party too. In summer, fresh berries shine brightest, but this recipe holds up beautifully with frozen fruit, making it a year-round treat.

Equipment Needed

• Baking sheet or slab pan (roughly 9×13 inches or larger), preferably rimmed for easy handling
• Mixing bowls: one for the dough, one for the filling
• Rolling pin (a sturdy one helps, but a clean wine bottle can work in a pinch)
• Pastry cutter or fork for cutting butter into flour (or your hands if you like to get messy)
• Sharp knife or pizza cutter for trimming dough and cutting the star shapes
• Pastry brush for the egg wash
• Cooling rack to let the pie rest after baking

If you don’t have a rolling pin, using parchment paper to roll out the dough helps avoid sticky messes. A rimmed baking sheet is essential since the juicy berry filling bubbles up and you want to keep it contained. I’ve tried this pie on a glass dish before, but it doesn’t bake quite as evenly, so I stick to metal pans now. A star-shaped cookie cutter or a small sharp knife will be your best friend for the lattice design—no fancy tools needed, just a little patience!

Preparation Method

1. Make the crust: In a large bowl, whisk together 2 ½ cups flour, sugar, and salt. Add the cold cubed butter and cut it into the flour with a pastry cutter or your fingers until the mixture looks like coarse crumbs with some pea-sized bits. This usually takes about 3-5 minutes.
2. Add ice water: Sprinkle 6 tablespoons of ice-cold water over the mixture, stirring gently with a fork. Add more water a tablespoon at a time just until the dough starts to come together. It should hold when squeezed but not be sticky. Form the dough into two discs, wrap in plastic, and chill in the fridge for at least 30 minutes.
3. Prepare the filling: In a bowl, combine the strawberries, blueberries, sugar, cornstarch, lemon zest, lemon juice, cinnamon, and vanilla. Toss gently until the berries are evenly coated. The cornstarch will help thicken the juices as it bakes, so don’t skip it!
4. Roll out the dough: On a lightly floured surface, roll out one disc of dough into a rectangle roughly the size of your baking sheet (about 12×16 inches). Transfer it carefully onto the rimmed baking sheet, pressing gently into the corners.
5. Add the filling: Spread the berry mixture evenly over the dough, leaving a 1-inch border around the edges.
6. Create the star lattice: Roll out the second disc of dough and cut strips about 1 inch wide. Using a star-shaped cookie cutter, cut stars out of the strips and arrange them in a lattice pattern over the berries. Overlap the stars slightly to hold them together. Don’t worry if it’s not perfect; charm is in the rustic look.
7. Seal and finish: Fold the edges of the bottom crust over the lattice, pinching gently to seal. Brush the entire top with the beaten egg to get a shiny golden finish. Sprinkle coarse sugar over the egg wash for a bit of crunch.
8. Bake: Preheat your oven to 375°F (190°C). Bake the slab pie for 45-50 minutes or until the crust is golden and the filling is bubbling. Keep an eye in the last 10 minutes; if the edges brown too quickly, cover them loosely with foil.
9. Cool and serve: Let the pie cool on a rack for at least 1 hour to allow the filling to set. Then slice into squares and enjoy. This pie pairs wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream.

Pro tip: If your crust feels tough, it might be because the butter got too warm. Always work quickly and keep ingredients cold for best flakiness. And don’t forget to save a few star cutouts to decorate the top—that little detail always gets compliments!

Cooking Tips & Techniques

Baking this easy rustic strawberry blueberry slab pie with star lattice is straightforward, but a few tips can help you get that bakery-worthy result without stress.

• Keep everything cold: Cold butter and water are your crust’s best friends. If the butter melts too soon, your crust can turn tough instead of tender and flaky.
• Don’t overwork the dough: Mix just until the dough holds together. Over-kneading develops gluten, making the crust chewy rather than light.
• Drain frozen berries: If using frozen fruit, thaw and drain excess juice before mixing with sugar and cornstarch to avoid a soggy bottom crust.
• Use cornstarch or tapioca starch: These thickeners help keep the filling from running but don’t make it gummy. I’ve learned the hard way that too much flour dulls the flavor and texture.
• Watch your oven: Every oven is different. Check the pie after 40 minutes to adjust baking time and prevent burning. Tent with foil if edges brown too fast.
• Multitasking tip: While the pie bakes, you can prepare a quick whipped cream or even the creamy herb and garlic cheese ball bites for a savory snack to balance the sweetness.

Honestly, it’s a forgiving recipe that lets you learn as you go. My first attempts didn’t have the star lattice (I was too nervous!), but once I tried it, the pie felt a little more special and definitely more fun to share. The key is to enjoy the process and not stress the tiny imperfections—rustic is the point!

Variations & Adaptations

This slab pie is versatile and can easily be adapted to suit different tastes or dietary needs.

• Seasonal swaps: In late summer, mix in fresh peaches or raspberries with the berries for a different flavor profile. Fall lovers might add chopped apples with cinnamon and nutmeg to the filling.
• Gluten-free crust: Use a gluten-free flour blend designed for baking. Keep the butter cold and handle gently for the best results. I’ve done this with almond flour additions for a nutty twist.
• Vegan adaptation: Replace butter with solid coconut oil or vegan butter and use a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water) for the egg wash. The pie still bakes up beautifully and tastes just as good.
• Alternative lattices: If stars feel tricky, try a simple woven lattice or even rustic strips for a different look. Another fun idea is cutting out small shapes (hearts, leaves) and scattering them on top.
• Sweetener swaps: Use honey or maple syrup instead of granulated sugar for a more natural sweetness and a subtle flavor change.

One of my favorite tweaks was adding a splash of balsamic vinegar to the berry filling—sounds odd, but it brought out the berries’ depth wonderfully. If you’re curious about more creative savory options, you might find the roasted red pepper hummus recipe with za’atar spice a flavorful inspiration for your next snack board alongside this pie.

Serving & Storage Suggestions

This rustic slab pie is best served at room temperature or slightly warm. Right out of the oven, it pairs beautifully with vanilla ice cream, whipped cream, or even a drizzle of honey for extra sweetness.

For a casual summer gathering, cut the pie into squares and serve on a wooden board with fresh mint leaves for a pop of color. It also makes a lovely afternoon treat with a cup of tea or lemonade.

To store, cover the pie loosely with plastic wrap or foil and keep it in the refrigerator for up to 3 days. The crust will soften a bit but remains delicious. If you want to keep it longer, wrap tightly and freeze for up to 2 months. Reheat slices gently in a warm oven (about 325°F/160°C) for 10-15 minutes to refresh that flaky crust.

Flavors develop wonderfully after resting overnight as the juices meld with the crust, so sometimes I bake the pie a day ahead for an even tastier experience.

Warm slices in a 325°F (160°C) oven for 10-15 minutes to refresh the crust’s flakiness. Avoid microwaving to keep the crust crisp.
