Ingredients You’ll Need
This recipe is a lovely example of how a handful of straightforward, everyday ingredients can come together to create magic. Each component plays its essential role, from the tartness of rhubarb to the creamy custard base, creating a beautiful harmony of taste and texture.
- 3 cups chopped fresh rhubarb: Fresh rhubarb provides the signature tartness and vibrant pink color essential to this pie.
- 3 large eggs: Eggs bind the custard, offering richness and a smooth, creamy consistency.
- 1 1/2 cups granulated sugar: Sweetens the tart rhubarb, balancing the flavors perfectly.
- 1/2 cup all-purpose flour: Adds structure to the custard, helping it set just right.
- 1/2 teaspoon salt: A pinch of salt enhances all the flavors without adding saltiness.
- 1 teaspoon vanilla extract: Brings a warm, aromatic depth that complements the fruit beautifully.
- 1 1/2 cups whole milk: Provides the creamy base for the custard with a luscious mouthfeel.
- 2 tablespoons unsalted butter, melted: Adds richness and a silky finish to the custard.
How to Make Crustless Rhubarb Custard Pie Recipe
Step 1: Prepare Your Oven and Pie Dish
Start by preheating your oven to 350°F (175°C). While it warms up, lightly grease a 9-inch pie dish to prevent the custard from sticking and ensure an easy slice once baked.
Step 2: Layer the Rhubarb
Evenly spread the chopped fresh rhubarb across the bottom of your greased pie dish. This layer forms the delightful foundation of your pie, bursting with tang and texture in every bite.
Step 3: Mix the Custard
In a mixing bowl, whisk together the eggs, granulated sugar, flour, salt, vanilla extract, whole milk, and melted butter until the mixture is completely smooth and well combined. This custard mix will cradle the rhubarb and bake into that luscious, soft filling.
Step 4: Pour and Bake
Carefully pour your custard mixture over the rhubarb in the pie dish, letting it settle evenly. Place it in the oven and bake for 45 to 50 minutes. Look for a lightly golden top and a center that’s just set—no jiggle—before you take it out to cool.
Step 5: Cool and Serve
Let your pie cool completely before slicing. This allows the custard to firm up to perfection, making serving slices easy and delightful. You can enjoy it chilled or at room temperature, whichever you prefer.
How to Serve Crustless Rhubarb Custard Pie Recipe

Garnishes
A scoop of vanilla ice cream or a dollop of freshly whipped cream will make your crustless rhubarb custard pie feel extra special. For a little added texture and color, sprinkle some finely chopped toasted almonds or a light dusting of powdered sugar as a finishing touch.
Side Dishes
This pie pairs wonderfully with a simple green salad if you’re serving it as part of a brunch spread. Its sweet and tart qualities also contrast nicely with a cup of freshly brewed coffee or a light herbal tea for a cozy afternoon treat.
Creative Ways to Present
Try serving individual portions in pretty ramekins for a charming appetizer-style dessert. You can even drizzle a bit of berry coulis or honey across the top for extra flavor and visual appeal, making your Crustless Rhubarb Custard Pie Recipe feel like a gift at any gathering.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover pie tightly with plastic wrap or cover with a pie saver, and store it in the refrigerator. It will keep deliciously fresh for up to three days, making it easy to enjoy more of this lovely dessert without fuss.
Freezing
This custard pie can be frozen, though it’s best enjoyed fresh. To freeze, slice the pie, wrap each slice in freezer-safe wrap, and place in an airtight container or heavy-duty freezer bag. Frozen slices maintain good texture for up to two months.
Reheating
Reheat slices gently in the microwave at low power or in a warm oven to protect the custard’s delicate texture. Enjoy your Crustless Rhubarb Custard Pie Recipe warm or let it cool again, depending on your mood.
FAQs
Can I use frozen rhubarb for this pie?
Yes, you can use frozen rhubarb if fresh isn’t available. Just be sure to thaw it first and drain excess moisture to avoid a watery pie.
Why does this pie have no crust?
The pie is designed to be crustless because the combination of rhubarb and custard bakes into a soft, naturally formed base, giving a comforting, tender texture without any added crust.
Can I substitute the whole milk with something else?
Whole milk gives the custard a rich texture, but you can use 2% milk or even a creamy plant-based milk like oat milk for a dairy-free twist; just note the flavor and texture will vary slightly.
What if my rhubarb is very tart?
If your rhubarb tastes extra tangy, sprinkle an extra tablespoon of sugar on top before baking to beautifully balance the flavors.
How do I know when the pie is done?
The pie is ready when the custard is set in the center and the top is a light golden color. A gentle shake of the pan should reveal little to no jiggle in the center.
