Ingredients for Strawberry Rhubarb Custard Pie Recipe
Gather these simple ingredients – you probably have most in your kitchen already! The magic happens when they all come together:
- 1 (9 inch) unbaked pie crust (homemade or store-bought – no judgment here!)
- 3 cups rhubarb, sliced 1/4-inch thick (about 4 medium stalks)
- 1 cup fresh strawberries, hulled and quartered
- 3 large eggs (room temperature helps the custard come together smoothly)
- 1 ½ cups white sugar (yes, it seems like a lot but trust the process)
- 3 tablespoons whole milk (2% works in a pinch)
- 3 tablespoons all-purpose flour (the secret thickener)
- ¼ teaspoon freshly grated nutmeg (makes all the difference)
- 1 tablespoon cold butter, diced into tiny pieces
- 2 tablespoons strawberry jam + ¼ teaspoon water (for that gorgeous glaze)
Ingredient Notes & Substitutions
No fresh rhubarb? Frozen works too – just thaw and drain really well to avoid a soggy pie. Want less sugar? Try 1 1/4 cups – the fruit’s tartness will shine more. Out of nutmeg? A pinch of cinnamon adds warmth. For dairy-free, almond milk swaps in beautifully. The jam glaze is optional but gives that bakery-worthy finish.

Equipment You’ll Need
For pie perfection, grab these trusty tools:
- 9-inch pie plate (I love glass for seeing the crust color)
- Mixing bowls (one medium for filling, small for glaze)
- Whisk (to blend that custard smooth)
- Baking sheet (catches drips and helps even baking)
- Pastry brush (optional but great for the glossy jam glaze)
- Knife and cutting board (for prepping fruit)
That’s it! No fancy gadgets needed – just basic kitchen essentials.
How to Make Strawberry Rhubarb Custard Pie Recipe
Okay, let’s get baking! This pie comes together so easily – just follow these simple steps:
- Preheat that oven! Crank it to 350°F (175°C) and let it heat up while you prep. Slide your pie crust into a 9-inch pie plate and set it on a baking sheet – this catches drips and makes rotating easier later.
- Toss those gorgeous fruits together in a bowl – the ruby red rhubarb and jewel-like strawberries. Spread them evenly in your waiting pie crust. Don’t pack them too tight – let them breathe!
- Whisk up the custard magic: In another bowl, beat the eggs lightly first, then whisk in sugar, milk, flour and that fragrant nutmeg until smooth as silk. No lumps allowed! Pour this golden liquid over the fruit – it’ll seep into all the nooks.
- Dot with butter – those little cubes will melt into pockets of richness. Gently tap the pie plate on the counter a few times to release any sneaky air bubbles.
- Bake for about 1 hour, turning halfway through. You’ll know it’s done when the custard barely jiggles in the center and the crust is golden. If edges brown too fast, tent with foil.
- Glaze it pretty: Warm the jam with water until runny, then brush over the warm pie. This adds shine and intensifies the strawberry flavor. Let cool completely before slicing – I know, the wait is torture!
Tips for Perfect Strawberry Rhubarb Custard Pie
Here are my hard-won secrets:
- Patience pays: Let the pie cool fully so the custard sets properly – cutting warm makes a mess!
- Check doneness by inserting a knife near the center – it should come out clean, not wet.
- Foil is your friend if the crust browns too quickly – just loosely cover the edges after 30 minutes.
- Room temp ingredients help the custard blend smoothly without curdling.
Follow these tips and you’ll get that perfect custard texture every time – creamy, not runny! If you’re looking for other fruit desserts, try my cherry crumble pie recipe.

Serving Suggestions for Strawberry Rhubarb Custard Pie
This pie shines brightest at room temperature – the custard sets perfectly but stays luscious. For extra indulgence, top slices with a scoop of vanilla ice cream that melts into the warm fruit, or a dollop of fresh whipped cream. A dusting of powdered sugar makes it extra pretty for guests!
Storage & Reheating Instructions
This pie keeps beautifully in the fridge for up to 3 days – just cover it loosely. To reheat, pop a slice in the oven at 300°F until just warm. Whatever you do, don’t microwave it – that turns the lovely custard texture rubbery! You can find more storage tips on my Facebook page.

Strawberry Rhubarb Custard Pie Recipe FAQs
I get asked these questions all the time – here’s everything you need to know:
How do I prevent a runny pie?
The secret’s in the bake time – don’t pull it out until that custard barely jiggles in the center. And please, please let it cool completely before slicing! I know it’s tempting, but that cooling time lets the custard set properly.
Can I use frozen rhubarb?
Absolutely! Just thaw it first and squeeze out all that extra liquid with your hands or a clean towel. Frozen works great when fresh isn’t in season.
How long does this pie stay good?
It keeps beautifully in the fridge for about 3 days. The flavors actually deepen overnight – if it lasts that long!
What if my crust browns too fast?
No worries! Just loosely tent the edges with foil after about 30 minutes of baking. This slows down the browning while the custard finishes setting.
Can I make this ahead?
You bet! Bake it the day before and store at room temp overnight. The custard sets even better after resting.
