The Perfect Rhubarb Pie in Simple Steps
- Preheat your oven to 425°F this high initial temperature helps create that perfectly flaky crust we’re all after.
- Prepare your rhubarb by washing thoroughly and chopping into ½-inch pieces. Don’t worry about peeling those beautiful red skins add color and flavor!
- In a large bowl, toss your rhubarb pieces with sugar, a touch of flour for thickening, a pinch of salt, and that secret ingredient lemon zest which brightens the whole pie.
- Roll out your bottom crust and place it in your pie dish. Don’t stress if it’s not picture-perfect those rustic edges are part of the charm of an old-fashioned pie!
- Pour in your rhubarb filling, dot with small pieces of butter (trust me on this one), and cover with your top crust. If you’re feeling fancy, try a lattice top it’s not just pretty, it helps the steam escape!
- Brush with egg wash for that golden shine, sprinkle with a little sugar for sparkle, and pop it in the oven.
- After 15 minutes, lower the temperature to 350°F and bake for another 40-45 minutes until the filling is bubbling and the crust is golden brown.
- Here’s the hardest part let it cool for at least 2 hours before slicing. I know, I know, but this waiting time allows the filling to set properly!
Baking Tips From My Kitchen to Yours
If your rhubarb is particularly juicy, add an extra tablespoon of flour to prevent a soggy bottom. Nobody likes a soggy bottom on pies or otherwise!
For an extra special touch, try adding a handful of strawberries to your filling. The strawberry-rhubarb combination is classic for a reason!
Don’t have fresh rhubarb? Frozen works too! Just thaw and drain excess liquid before using.
I learned the hard way that placing your pie on a baking sheet saves oven cleanup if the filling bubbles over. Nothing ruins a baking day like the smell of burning sugar!
A Slice of Nostalgia
The first time I made this pie, my kitchen filled with that unmistakable aroma that instantly transported me back to my grandmother’s farmhouse kitchen. There’s something about the sweet-tart smell of rhubarb baking that feels like a warm hug from the past.
This recipe has become my spring tradition, marking the season’s arrival as surely as the first robin. When those ruby stalks appear at the farmers’ market, my family knows what’s coming and the pie rarely lasts beyond a single evening!
Serving Suggestions
Serve your pie slightly warm with a scoop of vanilla ice cream for the ultimate comfort dessert. The contrast between the warm, tart filling and cold, creamy ice cream is simply divine.
For breakfast (yes, I said breakfast life’s too short!), a slice of cold rhubarb pie with your morning coffee is a treat you absolutely deserve.
