Rhubarb Meringue Pie
This stunning Rhubarb Meringue Pie layers a silky, tart rhubarb custard beneath billowy toasted meringue in a buttery crust. It is the ultimate spring showstopper that balances bold flavor with elegant presentation.
The Tart, Dreamy Pie You Make Once and Crave Every Spring After
Rhubarb has a way of dividing the room. Some people have never cooked with it. Others grew up pulling stalks straight from the garden and eating them with a pinch of sugar. But here is the thing: Rhubarb Meringue Pie converts everyone. The filling is silky and deeply tart, the meringue is cloud-soft and just sweet enough, and together they create a balance that feels genuinely sophisticated without being fussy.
This is the kind of pie that gets passed down. It has that old-fashioned soul that makes people ask, "Wait, you made this?" with genuine disbelief.
Why This Recipe Works
A lot of rhubarb pies lean entirely on sugar to tame the tartness. This one takes a smarter approach. By cooking the rhubarb down into a thick, jammy custard with egg yolks and a touch of flour, you get a filling that is rich and smooth rather than watery or sharp. The yolks add body. The butter adds gloss. And the vanilla quietly ties everything together.
Then comes the meringue. Made with the leftover egg whites, it does double duty: it adds sweetness and creates a dramatic visual finish. When those glossy peaks catch color in the oven, the whole pie looks like something out of a bakery window.
Chef's Tip: Room temperature egg whites whip up faster and reach greater volume than cold ones. Pull your eggs from the fridge at least 30 minutes before you start.
A Note on Tools and Rhubarb
Fresh rhubarb is ideal here, bright red stalks with a firm snap, but frozen works in a pinch (just drain it well after thawing). For the meringue, a stand mixer or a quality hand mixer with a whisk attachment will save you a lot of effort and give you that tall, glossy peak you are aiming for.

Getting the Meringue Right
The single most important rule for meringue success is this: spread it onto a warm filling, not a cold one. When the rhubarb base is still warm, the meringue bonds to it as it bakes, which prevents that dreaded weeping layer of liquid underneath.
Also make sure the meringue reaches all the way to the crust edge. Any gaps let steam escape underneath and cause shrinking. Seal it like you mean it.
Here is how the meringue should look before it goes into the oven:
- Stiff, not droopy. The peaks should hold their shape when you lift the spoon.
- Glossy, with a smooth, satin sheen.
- Bright white, with no visible graininess from undissolved sugar.
From Garden to Table
If you have never cooked rhubarb before, do not be intimidated by its looks. It behaves a bit like celery in the raw but transforms completely with heat and sugar. Within about 10 minutes on the stove, those firm, tart pieces collapse into a gorgeous pink compote that smells absolutely wonderful.
For color, deeply red stalks give the filling a rosy blush that looks beautiful under the white meringue. Greener stalks taste identical but produce a more muted, khaki-toned filling. Both are delicious.

Rhubarb Meringue Pie
This stunning Rhubarb Meringue Pie layers a silky, tart rhubarb custard beneath billowy toasted meringue in a buttery crust. It is the ultimate spring showstopper that balances bold flavor with elegant presentation.
Ingredients
- 1 pre-baked 9-inch pie shell, store-bought or homemade, cooled completely
- 3 cups fresh rhubarb, trimmed and cut into 0.5-inch pieces
- 1 1/4 cups granulated sugar, divided: 1 cup for filling, 0.25 cup for meringue
- 3 tbsp all-purpose flour
- 3 large eggs, yolks and whites separated, room temperature
- 1/2 cup whole milk
- 2 tbsp unsalted butter, cut into small pieces
- 1/2 tsp vanilla extract
- 1/4 tsp cream of tartar
- 2 tbsp powdered sugar, sifted, for finishing the meringue
Instruction
Preheat the oven to 325 degrees F (165 degrees C).
In a medium saucepan over medium heat, combine the rhubarb pieces and 1 cup of the granulated sugar. Cook, stirring occasionally, until the rhubarb breaks down completely and the mixture is soft and jammy, about 10 to 12 minutes.
In a small bowl, whisk together the flour, egg yolks, and milk until completely smooth. Slowly pour this mixture into the hot rhubarb, stirring constantly.
Continue cooking over medium-low heat, stirring constantly, until the filling thickens noticeably and begins to bubble, about 4 to 5 minutes.
Remove from heat and stir in the butter and vanilla extract until the butter is fully melted and incorporated. Let the filling cool for 5 minutes, then pour it into the pre-baked pie shell.
In a clean, dry bowl, beat the egg whites and cream of tartar with a hand mixer or stand mixer on medium speed until foamy. Gradually add the remaining 0.25 cup of granulated sugar and the powdered sugar, one tablespoon at a time, increasing speed to high. Beat until stiff, glossy peaks form.
Spoon the meringue over the warm rhubarb filling, spreading it all the way to the crust edges to seal completely. Use the back of a spoon to create decorative peaks and swoops across the surface.
Bake for 18 to 22 minutes, or until the meringue peaks are golden brown.
Remove from the oven and let the pie cool completely at room temperature for at least 2 hours before slicing. Do not refrigerate until fully cooled.
Equipment
- 9-inch pie dish
- Medium saucepan
- Stand mixer or hand mixer
- Mixing bowls
- Whisk
- Rubber spatula
- Measuring cups and spoons
Notes
Serving and Storing
Let the pie cool completely at room temperature before you slice it. This step is non-negotiable. Cutting into a warm meringue pie results in a runny filling and a collapsed topping. Give it a full two hours, and it will reward you with clean, picture-perfect slices.
For leftovers, cover loosely and refrigerate for up to two days. The meringue will soften slightly by day two, but the flavor is still wonderful. A hot, clean knife dipped in warm water between each slice keeps everything looking sharp.
