Strawberry Rhubarb Pie

Seriously, no joke, this is the best Strawberry Rhubarb Pie recipe. It’s the one my mom, and before that, my grandma has made for years. It’s a classic recipe with simple, delicious ingredients. Juicy strawberries are mixed with tart rhubarb, cane sugar, lemon and a little cornstarch under a flaky butter crust. Perfect with vanilla ice cream or softly whipped cream on the side. A classic fruit pie is one of my go-to spring desserts.

Not only does it make for a super delicious treat, but it’s bright and cozy at the same time. Also, there’s no complicated method or hard-to-find ingredient needed. And weekend prep’s a cinch. I often bake one on Saturday to enjoy after dinner and again on Sunday. If you love strawberry bakes, try our Strawberry Cream Cheese Muffins. With just a few basic ingredients, you probably have most of what you need.

No special trip required. Serve the finished pie after brunch or carry it to a potluck. Or add vanilla ice cream and turn each slice into a fancy little dessert that still feels wonderfully homemade. The sweet-tart filling does all the work. And those ruby juices make every wedge look special.

Ingredients

Here’s what I use for this recipe and you can always make substitutions if you prefer.

• fresh strawberries: Hulled and quartered after measuring whole fruit for firm ruby pieces.
• fresh rhubarb stalks: Trimmed and sliced into 1/2-inch pieces so the stalks soften at the same rate.
• granulated cane sugar: Whisked with the thickener to sweeten the tart fruit evenly.
• cornstarch: Coats the fruit juices and sets the filling after sustained bubbling.
• fine sea salt: Balances the sugar and sharpens the strawberry flavor.
• fresh lemon juice: Adds brightness and keeps the filling from tasting flat.
• pure vanilla extract: Rounds out the fruit with a soft aromatic note.
• refrigerated all-butter pie crust: Kept between 38°F and 42°F so the bottom crust and lattice stay flaky.
• unsalted European-style butter: Cut into small cold cubes and dotted over the fruit for richness.
• large egg: Beaten with milk to create a thin glossy wash.
• whole milk: Whisked into the egg so the crust browns evenly without becoming leathery.
• turbinado sugar: Scattered over the lattice for visible crunch and caramelized sparkle.
• vanilla bean ice cream: Scooped onto cooled slices just before serving for a creamy contrast.
• powdered cane sugar: Dusted lightly over the plated slice for a soft bakery-style finish.

Tools You’ll Need

• 9-inch clear glass pie plate: A 9-inch clear glass plate shows bottom browning and supports the crimped rim, while a shallow disposable tin can buckle and bake unevenly.
• Large clear glass mixing bowl: A 4-quart glass bowl gives the fruit room to fold without crushing, while a smaller bowl forces berries against the sides.
• Rimmed baking sheet: A heavy 13-by-18-inch rimmed sheet catches bubbling juice and steadies the pie, while a flat sheet lets sticky drips reach the oven floor.
• Pastry wheel or sharp chef’s knife: A straight-edged cutter makes eight clean 1-inch lattice strips, while a dull blade drags and warms the chilled dough.
• Silicone pastry brush: A 1-inch soft silicone brush spreads a thin egg wash without tearing dough, while stiff bristles leave pools that brown too fast.
• Oven thermometer: A hanging oven thermometer verifies the 425°F start and 375°F finish, while an inaccurate oven can leave the base pale or scorch the rim.

Instructions

Step 1: Slice the strawberries and rhubarb

Preheat the oven to 425°F. Keep the strawberries and rhubarb near 40°F until cutting. Hull and quarter the strawberries. Then slice the rhubarb into 1/2-inch pieces for 8 to 10 minutes.

Use steady downward cuts and rotate thick stalks between slices. Keep both fruits in separate uneven piles so their measured volumes stay reliably accurate. Next, check the cut surfaces. The strawberries should look juicy but firm and the rhubarb should snap cleanly with pale centers.

Soft berries smear and watery stalks weaken the filling. Miss the 10-minute window in a warm kitchen and the fruit starts leaking before mixing. Cold cutting preserves structure during the long bake.

Tip: Measure fruit after slicing, because oversized pieces leave empty pockets and make each wedge harder to cut cleanly.

Step 2: Coat the fruit and rest the filling

Transfer the 3 cups quartered strawberries and 3 cups sliced rhubarb into a large bowl at 68°F to 72°F. Whisk the granulated cane sugar, cornstarch and fine sea salt first. Then scatter the dry mixture over the fruit. Add lemon juice and vanilla.

Fold from the bottom with broad turns for 60 to 90 seconds. Let the mixture stand for exactly 10 minutes. Meanwhile, fold once at minute 5 so every piece gains a thin glossy coating. You should see a small ruby puddle at the bowl’s base and smell fresh lemon.

Stir longer and the berries crush. Skip the rest and dry starch pockets remain. Brief maceration dissolves sugar while cornstarch coats the released juice.

Tip: Recover every starch-coated drop, but leave crushed strawberry pulp behind when it gathers at the bowl’s bottom.

Step 3: Fill the bottom crust

Keep both refrigerated all-butter pie crusts between 38°F and 42°F. Press one crust into a 9-inch clear glass pie plate within 5 minutes. Smooth the base with flat fingertips and leave a 1-inch overhang. Then spoon in the rested fruit and its juices.

Dot the top with 1 tablespoon cold butter cubes. Next, spread the filling into a low uneven mound with more fruit near the center. The dough should look matte and flexible without greasy patches. The filling should remain glossy and chunky.

Warm dough slumps below the rim and tears during weaving. Overfill the edges and juice seals the crust poorly. Chilled dough traps distinct butter layers for a flaky base.

Tip: Set the glass pie plate on a rimmed baking sheet before filling, which catches drips without warming the bottom crust.

Step 4: Weave and finish the lattice

Cut the second chilled crust into eight uneven 1-inch strips at 40°F or colder. Weave four strips each direction across the filling in 6 to 8 minutes. Fold alternating strips back and lay each cross strip down. Trim the ends and crimp both crusts together with uneven thumb presses.

Chill the assembled pie for 15 minutes. Meanwhile, heat the oven to 425°F. Beat the large egg with whole milk and brush a thin coat over the lattice. Scatter turbinado sugar across the damp crust.

The dough should feel firm and the sugar crystals should stay visible. Rush the chill and the lattice spreads. Soak the crust and egg pools brown too fast. Firm butter keeps the lattice defined during the first heat blast.

Tip: Freeze the cut lattice strips for 5 minutes if your kitchen is above 75°F, so they weave without stretching.

Step 5: Bake until the center bubbles

Set the chilled Strawberry Rhubarb Pie in a 425°F oven and bake for 20 minutes. Then lower the oven to 375°F without opening the door. Continue baking for 35 to 40 minutes. Rotate the pie 180 degrees at minute 30.

Cover only the crimped rim when it reaches deep gold. (My first batch stayed at 400°F, the rim darkened too early). Finally, watch the center gaps rather than the edge bubbles. Thick ruby filling must bubble slowly through at least three lattice openings for 5 full minutes.

The crust should turn deep golden with lighter buttery patches. Pull it early and the center stays loose. Bake past 60 minutes and strawberry pieces collapse. Sustained bubbling activates the cornstarch throughout the deepest filling.

Tip: Place a foil shield over the rim only after it turns golden, usually during the final 20 minutes.

Step 6: Cool and plate one slice

Cool the baked pie in its glass plate at 68°F to 72°F for 4 hours. Don’t cover it during this time. Then cut one wedge with a clean downward motion and lift it onto a white dessert plate.

Add a 1/3-cup scoop of vanilla bean ice cream and dust with 1 teaspoon powdered cane sugar. The slice should hold a glossy jewel-red center with visible strawberry quarters and short rhubarb pieces. You should hear the crust crack softly at the fork line.

Cut before 4 hours and hot juices flood the plate. Leave ice cream on longer than 5 minutes and it hides the lattice texture. Full cooling lets the starch gel set before slicing.

Tip: Warm the knife under hot water and wipe it dry between cuts for cleaner slices after the 4-hour rest.

Pro Tips

• Choose rhubarb stalks no wider than 1 inch, because thinner stalks soften evenly during the 55 to 60 minute bake.
• Keep both crust rounds at 38°F to 42°F, because warm butter smears and the bottom loses flaky layers.
• Measure 3 cups of each fruit after cutting, since heaped whole berries can add nearly 1 cup of unwanted juice.
• Chill the woven Strawberry Rhubarb Pie for 15 minutes before baking so the lattice holds its uneven handmade shape.
• Look for slow bubbles in at least three center openings for 5 full minutes, not just rapid edge bubbles.
• Rotate the glass pie plate after 30 minutes at 375°F when your oven browns more strongly at the back.
• Add 1 teaspoon finely grated orange zest to the filling for brighter perfume without changing the starch ratio.

• Add 1/2 teaspoon ground cardamom and 1 teaspoon orange zest for a floral citrus version. Keep the same bake time.
• Replace 1 cup fresh strawberries with 1 cup fresh raspberries for a sharper filling. Add 1 tablespoon extra cane sugar.
• Swap the lattice for a crumb topping. Mix 3/4 cup unbleached all-purpose flour, 1/2 cup light brown cane sugar and 6 tablespoons cold butter.
• Scatter 1/3 cup sliced almonds over the egg-washed lattice during the final 20 minutes. The delayed addition prevents burned nuts.

Storage Instructions

Cool Strawberry Rhubarb Pie for 4 hours before covering it. Refrigerate the whole pie in its glass plate under a fitted cover for up to 4 days. For freezing, wrap the fully cooled pie twice in plastic wrap and once in foil.

Freeze it for up to 3 months. Individual wedges also freeze well when separated with parchment inside an airtight container. Reheat chilled slices at 350°F for 12 to 15 minutes, then rest them for 5 minutes before serving.

Frozen slices need 20 to 25 minutes at the same temperature. Add vanilla bean ice cream only after reheating so it doesn’t soak the crust. Discard the pie if the filling smells fermented, shows fuzzy growth or leaks thin gray liquid around the fruit.
