This tangy rhubarb pie is a special treat, featuring a crispy crust and sweet filling that balances the tartness of rhubarb. It’s a perfect dessert for any occasion!
When I bake this pie, the smell fills my kitchen and makes everyone want a slice. It’s a great way to use rhubarb from the garden—if you can resist nibbling on it first! 😉
I love serving it warm with a scoop of vanilla ice cream on the side. Trust me, that combination is so satisfying. Give it a try for a delightful dessert experience!
Key Ingredients & Substitutions
Rhubarb: Fresh rhubarb is key here, bringing that zingy tartness. If you can’t find fresh rhubarb, frozen rhubarb works well. Just let it thaw and drain any excess liquid before using.
Sugar: Granulated sugar is what you need for the right sweetness. If you’re looking for a healthier option, consider using honey or agave nectar, but reduce the amount to about 1 cup, as they’re sweeter than sugar.
Flour: All-purpose flour is perfect for thickening the rhubarb juices. If you’re gluten-free, substitute with a gluten-free all-purpose blend. It works nicely too!
Cinnamon: This is optional but adds a warm flavor. If you’re not a fan, you can skip it, or swap it for nutmeg for a different twist. A pinch can really enhance the scent of your pie.
Vanilla extract: This boosts flavor but can be omitted if you prefer a more straightforward taste. If you want a unique flavor, try almond extract instead.
How Do You Make a Lattice Pie Crust?
Creating a lattice pie crust can seem tricky, but it adds a lovely touch to your pie! Here’s how to do it:
- Roll out your second half of the pie crust and cut it into 3/4-inch wide strips.
- Lay half of the strips parallel across the pie, spacing them evenly. Leave about an inch gap between them.
- Fold back every other strip, laying the next strip perpendicular across the center.
- Unfold the strips to create the crisscross pattern. Continue this process until the entire pie is covered.
- Trim, then crimp or fold the edges neatly!
Don’t worry if it’s not perfect; a rustic look adds character to your pie! This method lets steam escape and showcases the delicious filling inside.

How to Make Delicious Rhubarb Pie
Ingredients You’ll Need:
For the Filling:
- 4 cups rhubarb, cut into 1/2-inch pieces
- 1 1/3 cups granulated sugar
- 6 tablespoons all-purpose flour
- 1/2 teaspoon ground cinnamon (optional)
- 1/4 teaspoon salt
- 1 tablespoon butter, cut into small pieces
- 1 teaspoon vanilla extract (optional)
For the Crust:
- 1 double pie crust (store-bought or homemade)
- 1 egg, beaten (for egg wash)
- 2 tablespoons coarse sugar (for sprinkling on crust)
How Much Time Will You Need?
This rhubarb pie will take approximately 15 minutes to prepare, plus 50-55 minutes of baking time. Don’t forget to allow a cool-down period of at least 2 hours for the filling to set before serving. So overall, you’ll be spending roughly 3 hours, including preparation and cooling!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 425°F (220°C). This will ensure that your pie cooks evenly once it’s in the oven.
2. Prepare the Filling:
In a large bowl, mix together the rhubarb, sugar, flour, cinnamon (if you like), salt, and vanilla extract. Toss everything well until the rhubarb pieces are nicely coated. Set this mixture aside for a moment.
3. Prepare the First Crust:
Roll out one half of your pie crust and fit it snugly into a 9-inch pie plate. Make sure to trim any excess dough hanging over the edges to keep it neat.
4. Add the Filling:
Carefully pour the rhubarb filling into the prepared crust, spreading it out so it’s even.
5. Add Butter Pieces:
Dot the filling with small pieces of butter. This little touch adds delicious richness to your pie!
6. Prepare the Second Crust:
Roll out the second half of the pie crust. You can either create a pretty lattice design or simply place it whole over the filling. If you go with the whole crust, remember to cut a few vents to let the steam escape.
7. Seal the Edges:
Trim any extra dough from the edges and crimp them together to seal the pie. This step keeps the filling contained and creates a lovely border.
8. Brush and Sugar the Top:
Brush the top crust with the beaten egg. Then, sprinkle some coarse sugar over it for a nice crunch and golden color.
9. Bake the Pie:
Put the pie on a baking sheet (to catch any drips) and bake it in the preheated oven for 15 minutes.
10. Lower the Temperature:
After 15 minutes, reduce the oven temperature to 350°F (175°C) and continue baking the pie for an additional 35-40 minutes. You’ll know it’s done when the crust is golden brown and the filling is bubbling.
11. Cool the Pie:
Once baked, take the pie out of the oven and let it cool on a wire rack for at least 2 hours. This cooling time helps the filling to set properly, making it easier to slice later.
12. Serve and Enjoy:
Slice the pie and serve it warm or at room temperature. It’s delicious on its own or topped with whipped cream or vanilla ice cream for an extra treat!
Can I Use Frozen Rhubarb for This Pie?
Yes, you can use frozen rhubarb! Just make sure to thaw it completely and drain any excess liquid before mixing it with the other ingredients. This prevents a watery filling.
How Do I Store Leftover Rhubarb Pie?
Store leftover pie in an airtight container in the refrigerator for up to 3 days. You can also wrap it tightly in plastic wrap. To reheat, pop slices in the microwave or warm it in the oven at 350°F (175°C) for about 10-15 minutes.
What Can I Substitute for Flour in the Filling?
If you need a gluten-free option, you can substitute all-purpose flour with cornstarch or a gluten-free all-purpose flour blend. Use the same measurement for a good result!
Can I Make This Pie in Advance?
Absolutely! You can prepare the pie and store it unbaked in the freezer for up to a month. When you’re ready to bake, just pop it straight from the freezer into the oven, adding a few extra minutes to the baking time.
