Ingredients
For the Pie
- 1 unbaked 9-inch pie crust, homemade or store-bought
- 1½ cups chopped fresh rhubarb
- 1½ cups sliced strawberries
- ¾ cup granulated sugar
- 3 large eggs
- ½ cup heavy cream
- ¼ cup all-purpose flour
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
The flour helps thicken the custard, while the eggs and cream create its smooth texture. Vanilla rounds out the fruit’s natural flavor.
How to Make Strawberry Rhubarb Custard Pie
Step 1: Prepare the Oven and Pie Crust
Preheat your oven to 375°F (190°C).
Fit the unbaked pie crust into a 9-inch pie plate, pressing it gently into the edges. Crimp the rim if desired.
Place the pie plate on a baking sheet to make it easier to transfer to and from the oven and to catch any possible drips.
Step 2: Prepare the Fruit
Wash the strawberries and rhubarb. Remove the strawberry stems and slice the berries. Trim the rhubarb stalks and cut them into small pieces about ½ inch long.
If the strawberries are particularly juicy, gently blot away excess moisture with a paper towel. Spread the fruit evenly in the prepared pie crust.
Step 3: Make the Custard
In a medium mixing bowl, whisk together the eggs, sugar, heavy cream, flour, vanilla extract, and salt until the mixture is smooth and the flour is incorporated.
Whisk gently rather than vigorously to avoid creating too much foam.
Step 4: Assemble the Pie
Pour the custard mixture evenly over the strawberries and rhubarb. Gently move the fruit with a spoon if necessary so the custard reaches the spaces between the pieces.
Do not overfill the crust. If your pie plate is shallow, you may have a small amount of custard left over.
Step 5: Bake Until Set
Bake for approximately 45–60 minutes, checking toward the end of the baking time.
The crust should be golden, and the filling should look mostly set with a slight jiggle in the center. If the crust edges brown too quickly, cover them loosely with strips of aluminum foil.
For food safety and a properly set custard, the center should reach about 160°F (71°C). Avoid overbaking, which can make the custard rubbery or cause it to separate.
Step 6: Cool Before Slicing
Remove the pie from the oven and place it on a cooling rack. Allow it to cool for at least 2–3 hours so the custard can finish setting.
For the cleanest slices, refrigerate the cooled pie before cutting. Serve chilled or close to room temperature.
Tips for the Best Strawberry Rhubarb Custard Pie
Use fresh, firm rhubarb. Choose stalks that feel crisp and are free from soft or damaged spots. Rhubarb color varies naturally and does not determine its flavor by itself.
Cut the fruit evenly. Similar-sized pieces cook more consistently and make each slice easier to serve.
Measure the flour accurately. Too much flour can make the custard heavy, while too little may leave it loose.
Protect the crust. If the edges brown before the filling sets, cover them with foil or a pie crust shield.
Allow enough cooling time. Custard pies need time to firm up. Slicing while the pie is hot can leave the filling runny.
Avoid excess moisture. Very juicy strawberries can release extra liquid. Blotting them gently helps maintain a better custard texture.
Easy Variations
Add a Crumb Topping
Sprinkle a simple mixture of flour, sugar, and butter over the filling before baking for a lightly crisp topping. This adds extra ingredients and creates a more rustic finish.
Use Frozen Fruit
Frozen strawberries and rhubarb can work when fresh fruit is unavailable. Thaw and drain them thoroughly first, and expect that the pie may need a little extra baking time.
Add Lemon Zest
A small amount of lemon zest brightens the fruit flavor and complements the rhubarb’s natural tang.
Try a Cinnamon Note
Add a small pinch of cinnamon to the custard for a warmer, old-fashioned flavor.
Make It Without Heavy Cream
Whole milk can be used instead of heavy cream, although the custard will be less rich. The filling may also set a little differently.
What to Serve with Strawberry Rhubarb Custard Pie
This pie is delicious on its own, but it also pairs beautifully with:
- Freshly whipped cream
- A scoop of vanilla ice cream
- A spoonful of lightly sweetened yogurt
- Fresh strawberries on the side
- Coffee or tea after dinner
For a special dessert, serve each slice slightly chilled with a small scoop of vanilla ice cream.
Storage Instructions
Refrigerator: Because this pie contains an egg-and-cream custard, refrigerate it within 2 hours of baking or serving. Cover and store for up to 3–4 days.
Freezing: Custard pies may change texture after freezing and thawing, becoming watery or less smooth. Freezing is not recommended if you want the best custard texture.
Make-ahead tip: Bake the pie the day before serving, allow it to cool, and refrigerate it covered. This gives the filling plenty of time to set and makes slicing easier.
Frequently Asked Questions
Can I use frozen rhubarb?
Yes. Thaw it completely and drain away excess liquid before adding it to the crust. Extra moisture can prevent the custard from setting properly.
Why is my custard pie runny?
The pie may need more baking or cooling time, or the fruit may have released too much liquid. Check that the center is set and reaches approximately 160°F (71°C), then allow the pie to cool completely before slicing.
Do I need to cook the rhubarb before baking?
No. Finely chopped rhubarb can be added directly to the pie crust. It will soften as the pie bakes.
Can I make this pie a day ahead?
Absolutely. In fact, making it a day ahead is helpful because the custard has plenty of time to chill and firm up.
Should Strawberry Rhubarb Custard Pie be refrigerated?
Yes. The egg-and-cream filling is perishable, so store the pie in the refrigerator after it has cooled.
Can I use a store-bought pie crust?
Yes. A refrigerated or frozen 9-inch pie crust is a convenient option. Follow the package instructions for preparation, and check the pie during baking to avoid overbrowning.
