Looking for a dessert that perfectly balances sweet and tart flavors? This heavenly crustless rhubarb custard pie will transform your spring dessert game with its silky smooth texture that simply melts in your mouth. I’m excited to share this incredible recipe that celebrates one of spring’s most distinctive offerings: rhubarb!
Why This Crustless Rhubarb Custard Pie Will Become Your New Favorite
Spring brings with it the vibrant crimson stalks of rhubarb, and there’s no better way to showcase this seasonal treasure than in a custard pie that lets its unique flavor shine. What makes this rhubarb custard pie special is the absence of a traditional crust, allowing the creamy custard and tangy rhubarb to take center stage.
The magic happens when the tart rhubarb combines with the sweet, vanilla-infused custard, creating a harmonious balance that delights the palate. Additionally, the subtle hint of nutmeg adds a warm, aromatic dimension that elevates the entire dessert experience.
Many people shy away from rhubarb because they’re unsure how to prepare it properly. However, this foolproof recipe transforms those ruby stalks into something truly spectacular. The contrast between the soft, baked rhubarb and the silky custard creates a textural paradise that’s simply irresistible.

Ingredient Substitutions and Variations
One of the beautiful aspects of this rhubarb custard pie is its flexibility. While I recommend following the recipe as written for your first attempt, here are some variations you might consider:
Milk options: If you don’t have whole milk, you can use 2% milk, though the custard won’t be quite as rich. For an even more luxurious texture, try substituting half a cup of the milk with heavy cream.
Sugar alternatives: You can reduce the sugar slightly if you prefer a more pronounced tartness from the rhubarb. Brown sugar can also be used for a deeper, more caramel-like flavor profile.
Flavor enhancers: Add a teaspoon of lemon zest or a half teaspoon of cinnamon to introduce complementary flavor notes.
Fruit combinations: While pure rhubarb offers a classic experience, you can create a strawberry-rhubarb version by replacing one cup of rhubarb with sliced strawberries.

Step-by-Step Cooking Instructions
Step 1: Prepare the Rhubarb
First, preheat your oven to 350°F. While it’s warming up, wash your rhubarb stalks thoroughly and trim off the leaves (remember, rhubarb leaves are toxic and should never be consumed). Cut the stalks into roughly 1/2-inch pieces until you have 4 cups. Grease your 10-inch deep dish pie plate generously, then spread the chopped rhubarb evenly across the bottom.
Step 2: Create the Custard Base
In a large bowl, whisk together the eggs, sugar, flour, and salt until the mixture is smooth and well-combined. This step is crucial for ensuring your custard has the perfect texture – take your time to eliminate any lumps, especially from the flour.
Step 3: Add the Liquid Ingredients
Next, gradually stir in the milk, vanilla extract, and melted butter into your egg mixture. The melted butter enriches the custard and adds a subtle buttery note that complements the rhubarb beautifully. Whisk until everything is fully incorporated and the mixture has a uniform consistency.
Step 4: Assemble the Pie
Carefully pour your custard mixture over the rhubarb in the pie dish. The rhubarb may float initially – that’s completely normal! Sprinkle the nutmeg evenly across the top. This may seem like a small detail, but the nutmeg adds a wonderful aromatic quality that enhances the overall experience.
Step 5: Bake to Perfection
Place your pie in the preheated oven and bake for 50-60 minutes. You’ll know it’s done when the custard is set (with perhaps just a slight wobble in the center) and the top has turned a light golden color. The aroma that fills your kitchen during baking is absolutely heavenly!
Step 6: Cooling Period
This step requires patience but is essential for the perfect texture. Allow the pie to cool completely at room temperature. During this time, the custard will continue to set and the flavors will meld together beautifully.
Step 7: Serve and Enjoy
Once cooled, your rhubarb custard pie is ready to be served. For an extra special touch, add a dollop of whipped cream or a small scoop of vanilla ice cream on top.

Perfect Pairings for Your Rhubarb Custard Pie
This pie is delicious on its own, but it reaches new heights when served with complementary accompaniments:
- A dollop of freshly whipped cream adds a cloud-like softness
- A scoop of vanilla ice cream creates a wonderful hot-and-cold contrast
- A light dusting of powdered sugar adds visual appeal and a touch more sweetness
- A sprig of fresh mint provides a pop of color and refreshing aroma
Expert Tips for Rhubarb Custard Pie Success
- Use fresh rhubarb when possible, though frozen will work if thawed and drained well
- Don’t reduce the sugar too much as rhubarb is quite tart and needs sweetness for balance
- Check for doneness by gently jiggling the pie – the edges should be set with a slight wobble in the center
- Let it cool completely before refrigerating to prevent condensation from making the top soggy
- Bake on the middle rack of your oven for even heat distribution
Storage Instructions
This rhubarb custard pie keeps beautifully in the refrigerator. Simply cover it loosely with plastic wrap or place it in an airtight container and refrigerate for up to 3-4 days. The flavors actually continue to develop over time, making it even more delicious on day two!
While you can freeze portions of this pie for up to a month, be aware that the texture of the custard may change slightly upon thawing. To serve after freezing, thaw overnight in the refrigerator.
The Health Benefits of Rhubarb
While this dessert is certainly an indulgence, rhubarb itself offers some nutritional benefits. It’s high in vitamin K, which supports bone health, and contains antioxidants that help fight inflammation. Rhubarb is also a good source of fiber and relatively low in calories before the added sugar, of course!

Frequently Asked Questions
Can I use frozen rhubarb for this recipe?
Yes! Thaw it completely and drain excess liquid before using. You may need to add an extra 5-10 minutes to the baking time.
Why is my custard not setting properly?
The most common reason is underbaking. Every oven is different, so you may need to extend the baking time. The center should be mostly set with just a slight jiggle.
Can I make this pie ahead of time?
Absolutely! It actually tastes even better after the flavors have had time to meld in the refrigerator overnight.
Is rhubarb safe to eat?
The stalks are completely safe and delicious when cooked. However, never consume rhubarb leaves as they contain high levels of oxalic acid, which is toxic.
Can I add other fruits to this recipe?
Strawberries are the classic pairing with rhubarb, but raspberries and blackberries also work wonderfully. Replace up to half the rhubarb with your fruit of choice.
