Bright, tangy, and deeply comforting, this Orange Rhubarb Pie is a springtime showstopper that balances sharp rhubarb with sunny citrus.
It’s simple enough for a weekday baking session yet elegant for company.
The lattice top lets steam escape while showing off the jewel-toned filling.
If you love citrus-forward desserts, try pairing this with a creamy no-bake pie for contrast: creamy no-bake pistachio pie.

Key Ingredients for Orange Rhubarb Pie
Rhubarb: Fresh rhubarb is the backbone of this pie. Buy bright-colored stalks that are firm and crisp; avoid limp or overly woody pieces. If you substitute with frozen, thaw and drain first because excess water can dilute the filling.
Granulated sugar: Sugar balances rhubarb’s tartness and helps the filling set. For best texture use regular granulated sugar; swapping to a liquid sweetener will change set and baking time and can make the filling syrupy.
Cornstarch: This is the primary thickener and gives the filling that clear, glossy finish. If you replace it with flour, you’ll need more and the filling will be cloudier and less glossy. For a gluten-free option, cornstarch is already suitable; just ensure it’s mixed thoroughly to avoid lumps.
Pie pastry: A sturdy double-crust pastry supports the lattice and prevents soggy bottoms. Use a refrigerated or homemade pastry rolled to even thickness; a single crust won’t hold the lattice and filling the same way. If pressed for time, a high-quality store-bought double-crust works fine but check that it’s sturdy.
Full Ingredient List for Orange Rhubarb Pie
- 1 recipe pastry for a double crust pie
- 1-1/4 cups granulated sugar
- 1/4 cup cornstarch
- 1/4 teaspoon salt
- 1 pound (1 bunch) fresh rhubarb, cut in 1-1/2 inch lengths
- 2 teaspoons grated orange rind (or 1 tsp lemon rind)
- Juice of one fresh orange
- 2 tablespoons unsalted butter, cubed
- 1 tablespoon milk (for brushing)
- 1 tablespoon sugar (for topping)
Step-by-Step Instructions for Orange Rhubarb Pie
Step 1: Divide and prepare the pastry
Divide the pastry into two unequal halves so you have more to line the pan and less for the lattice. Roll out the larger portion on a floured surface into a circle large enough to fit a 9-inch pie pan and gently ease it into the pan, pressing to fit without stretching the dough. Trim the pastry about 1/2 inch beyond the rim so you can fold and create a high edge later.
Pro Tip: The shell should look smooth and without tears; if it collapses easily, chill it 10–15 minutes until firm to the touch.
Step 2: Roll and cut pastry strips for the lattice
Roll the remaining pastry to 1/8-inch thickness and slice strips approximately 3/4 inch wide with a pastry wheel or sharp knife. Keep strips on a lightly floured board and cover briefly so they don’t dry out while you assemble.
Pro Tip: Strips should be flexible and not cracked; if they crack at the edges, chill them briefly and roll again.
Step 3: Make the filling
In a large bowl, whisk together the sugar, cornstarch, and salt until fully combined. Add the rhubarb pieces, orange rind, and orange juice, tossing gently until every piece is coated with the dry mix and citrus.
Pro Tip: The coated rhubarb should glisten and not look dry; if it seems too wet, let it sit 5 minutes to absorb the sugar before filling.
Step 4: Optional color boost
If you prefer a vivid pink filling, add a drop of red food coloring and mix gently until color is even. This step is purely aesthetic and won’t change texture or flavor.
Pro Tip: The color should be subtle while raw; baking will deepen it.
Step 5: Fill the pie shell
Pour the rhubarb mixture into the prepared pastry shell and spread it evenly so the filling is level. Dot the surface with the small cubes of unsalted butter placed evenly across the top.
Pro Tip: The filling should mound slightly but not overflow; butter dots will melt into glossy pools as it bakes.
Step 6: Weave and seal the lattice
Arrange the pastry strips over the filling in a lattice pattern, alternating over and under to create a basket weave. Secure strip ends to the bottom crust, fold the bottom crust over the strip edges to create a high, sealed rim, and flute the edges for a decorative finish.
Pro Tip: The lattice should sit slightly above the filling; if a strip sinks into the filling it may be too thin or the filling too wet.
Step 7: Egg wash and sugar
Brush the lattice and edges lightly with milk to promote even browning and sprinkle the extra tablespoon of sugar over the top for sparkle and crunch.
Pro Tip: The brushed surface will look glossy and slightly slick before baking; sugar should sit visibly on top.
Step 8: Bake until done
Bake in a preheated 400°F (200°C) oven for 50–60 minutes. The pie is ready when the crust is deep golden and the filling bubbles vigorously in the center. Rotate halfway through baking if your oven has hot spots.
Pro Tip: Look for strong bubbling in the center and a deeply golden crust; if the edges brown too fast, tent with foil.
Expert Tips for Orange Rhubarb Pie
- Chill your crust: Keep pastry cold before baking to maintain flakiness and prevent shrinkage.
- Oven temperature: Start at 400°F for a crisp crust; if the top browns too quickly, reduce to 375°F and tent with foil.
- Filling set: Use the exact cornstarch amount; too little yields a runny pie, too much makes it gluey.
- Texture troubleshooting: If rhubarb is very tart, increase sugar by 1/4 cup; balance carefully to avoid over-sweetening.
- Equipment tip: Use a glass or ceramic pie dish for even baking; a metal pan browns faster.
- Rolling tips: Roll pastry between parchment for easy transfer and less handling.
- Common mistake: Overfilling makes the pie bubble over; leave a little room for the filling to expand.
- Visual cue: The lattice should be golden and have sugar crystals visible after baking; if it’s pale, bake longer at a slightly lower temperature.
Storage & Freezing for Orange Rhubarb Pie
Refrigerator storage: Cover cooled pie loosely with foil or plastic wrap and refrigerate for up to 4 days. Serve chilled or reheat slices to warm.
Freezer storage: Freeze a fully baked pie (wrapped tightly in plastic wrap and then foil) for up to 3 months. To freeze unbaked, assemble the pie, freeze on a tray until solid, then wrap; bake from frozen, adding 10–15 minutes to baking time.
Thawing: Thaw frozen baked pie in the refrigerator overnight. For faster thawing, place covered pie at room temperature for 2–3 hours.
Reheating: Warm slices in a 350°F oven for 10–15 minutes for a crisp crust. Avoid the microwave for extended heating to prevent soggy pastry.
Variations & Substitutions for Orange Rhubarb Pie
Strawberry-Orange Rhubarb: Add 1–1/2 cups sliced strawberries with the rhubarb and reduce sugar by 1/4 cup. The result is a juicier filling with a softer texture and rounded sweetness.
Orange-Almond Rhubarb: Stir in 1/2 cup finely ground almonds into the filling or brush slivered almonds onto the lattice before baking. You’ll get a nutty depth and slightly denser filling texture. See a similar almond pairing for inspiration with cranberry-orange cookie combinations.
Lemon Zest Swap: Use 1 teaspoon lemon rind instead of orange rind and keep the orange juice for acidity balance. This makes the tartness crisper and less sweet-scented.
Vegan Option: Replace butter with vegan butter or coconut oil in small cubes and brush pastry with non-dairy milk. The texture remains flaky though the crust will brown slightly differently.
Frequently Asked Questions About Orange Rhubarb Pie
Q: Can I use frozen rhubarb for Orange Rhubarb Pie?
A: Yes, frozen rhubarb can be used but thaw and drain it thoroughly first to remove excess liquid. Toss drained pieces with the sugar and cornstarch as directed, but expect a slightly softer texture and potentially a longer bake to evaporate extra moisture.
Q: How do I prevent a soggy bottom crust in Orange Rhubarb Pie?
A: Use a pre-chilled pie plate and dough, avoid overfilling, and ensure the cornstarch is fully mixed to absorb juices. Baking on the lower third of the oven for the first 20 minutes can help set the bottom crust; finish in the middle rack.
Q: Why didn’t my Orange Rhubarb Pie filling set?
A: Likely causes are insufficient cornstarch, too much liquid from overripe fruit, or not baking long enough for full bubbling. To fix, serve slightly chilled—chilling helps the cornstarch firm—or re-cook strained filling on the stovetop with more cornstarch and rebake.
Q: Can I make Orange Rhubarb Pie ahead of time?
A: Yes, assemble the pie and refrigerate for up to 24 hours before baking, but keep it covered. For longer prep, freeze an unbaked assembled pie and bake from frozen, adding 10–15 minutes.
Q: How can I get a bright pink filling without food coloring?
A: Use very fresh, red-stalk rhubarb and add some strawberries or raspberries to intensify color naturally. Also, avoid overcooking which can mute the hue.
