Ingredients for Strawberry Rhubarb Custard Pie Recipe

- 1 (9 inch) unbaked pie crust – homemade if you’re feeling fancy, but honestly? A good store-bought one works wonders too
- 3 cups rhubarb, sliced 1/4-inch thick – look for crisp, ruby-red stalks (the prettier they are, the sweeter they’ll taste)
- 1 cup fresh strawberries, quartered – I like to leave some bigger chunks for juicy bursts of flavor
- 3 large eggs at room temperature – this helps them blend smoothly into the custard
- 1 ½ cups white sugar – trust me, you need this much to balance the tartness
- 3 tablespoons milk – whole milk makes the custard extra rich
- 3 tablespoons all-purpose flour – our magic thickener
- ¼ teaspoon freshly grated nutmeg – just a whisper, but oh what a difference it makes
- 1 tablespoon butter, diced – little nuggets of golden goodness to dot the top
- 2 tablespoons strawberry jam + ¼ teaspoon water for that shiny glaze – bonus points if you use homemade jam!
See? Nothing too crazy – just simple ingredients that turn into something extraordinary when baked together with love.
How to Make Strawberry Rhubarb Custard Pie Recipe
Preparing the Crust and Filling
First things first – let’s get that crust ready! Preheat your oven to 350°F (175°C) – this gives the oven time to settle into the perfect temperature while we prep. Gently press your pie crust into a 9-inch pie plate and place it on a baking sheet lined with parchment paper (trust me, this catches drips and makes cleanup a breeze).

Now, toss together those gorgeous ruby-red rhubarb slices and plump strawberry quarters in a bowl – the colors alone make me smile! Spread them evenly in the crust – no clumping allowed! We want every bite to have that perfect fruit balance.
Mixing and Baking the Custard
Here’s where the magic happens! In a medium bowl, whisk together the eggs, sugar, milk, flour, and that fragrant nutmeg until smooth. Now pour this golden liquid over your fruit mountain – go slow, stop just before it reaches the crust’s edge (it rises a bit in the oven). Scatter those butter cubes over the top like little treasure nuggets.
Gently tap the baking sheet on the counter – listen for those tiny bubbles popping! That means we’re getting rid of air pockets that could crack our custard. Pop it in the oven and bake for about 1 hour, turning halfway through – this ensures even browning. You’ll know it’s done when the custard barely jiggles in the center and the rhubarb is fork-tender.
Glazing and Serving
Almost there! While the pie rests, mix strawberry jam with a splash of water and microwave for 15 seconds until it’s pourable. Brush this glossy goodness over the warm pie – it adds shine and intensifies that berry flavor. Now comes the hardest part: waiting!
Let it cool completely before slicing (I know, I know – but rushing means messy slices). The custard needs time to set properly. For picture-perfect wedges, refrigerate for at least 2 hours. Serve chilled with a dollop of whipped cream if you’re feeling fancy – though honestly, it’s spectacular all on its own!

Tips for the Best Strawberry Rhubarb Custard Pie Recipe
After making this pie more times than I can count, here are my hard-earned secrets:
- Fresh is best – spring for crisp, vibrant rhubarb stalks; limp ones won’t give you that perfect tart-sweet balance
- Don’t overfill! That custard rises like a champ – leave 1/4 inch at the top or you’ll have a sugary lake in your oven
- Patience pays off – let it cool completely before slicing (I stick mine in the fridge for a couple hours) for those clean, Instagram-worthy slices
- Watch your bake time – ovens vary! Start checking at 50 minutes – the custard should barely wiggle when gently shaken
Follow these, and you’ll have pie perfection every single time!
Ingredient Substitutions and Notes
Life happens, and sometimes we need to improvise! Here’s how to tweak things without losing that magic:
- Frozen rhubarb? Absolutely! Thaw completely and pat dry with paper towels – excess moisture makes for soggy crust
- Out of flour? Cornstarch works (use 1 1/2 tablespoons instead) but gives a slightly clearer custard
- No fresh strawberries? Frozen work in a pinch, but toss them in flour before adding to prevent juice puddles
- Dairy-free? Almond milk substitutes fine, but skip the butter topping or use coconut oil
Remember – every change affects the final texture slightly, but the flavors still shine through beautifully!
Serving and Storing Strawberry Rhubarb Custard Pie Recipe
Oh, this pie is best served chilled – trust me, that cold custard slice is pure heaven! I love adding a big dollop of fresh whipped cream on top. For storing, just pop any leftovers (if you’re lucky enough to have any!) in the fridge covered tightly with plastic wrap. It’ll stay dreamy for up to 3 days.
Strawberry Rhubarb Custard Pie Recipe FAQs
I get asked these questions all the time, so let’s tackle the big ones together!
Can I use frozen fruit instead of fresh?
Absolutely! Just make sure to thaw frozen rhubarb and strawberries completely and pat them really dry with paper towels. Otherwise, all that extra liquid will make your crust soggy and the custard might not set right.
Why did my custard crack?
Oh, that’s usually from overbaking or the oven temperature being too high. Next time, try pulling the pie out when the center still has just the tiniest jiggle – it’ll keep cooking as it cools. Also, that gentle tapping step before baking really helps prevent cracks!
Can I make this pie ahead of time?
You bet! This pie actually tastes even better the next day after the flavors have had time to mingle. Just bake it, let it cool completely, then keep it covered in the fridge. The cold slice is honestly my favorite way to eat it.
My pie is too runny – what went wrong?
That usually means it needed more time in the oven. The custard should be fully set before you take it out. Also, make sure you’re using the right amount of thickener (that flour measurement is key!) and your fruit wasn’t too wet going in.
