Ingredients You’ll Need

Here’s what goes into this spectacular pie, plus some handy notes for best results:

• Unbaked Pie Shell: The trusty foundation. Use store-bought for convenience, or homemade if you have a favorite recipe. Just keep it unbaked!
• Chopped Rhubarb: The shining star. Select fresh, firm stalks; trim away any leaves. If using frozen, thaw completely and pat dry—excess moisture is not your friend here.
• Granulated Sugar: Essential for balancing rhubarb’s tartness and sweetening the custard.
• Eggs (beaten): These work double duty, giving the custard its luxurious texture and helping it set.
• Heavy Whipping Cream: The secret to rich, dreamy custard. Don’t substitute with milk—the creaminess is key!
• Flour: Helps the custard thicken up just right, especially important if your rhubarb is a bit juicy.
• Salt: Just a pinch, but such a flavor enhancer—you’ll notice the difference.

Tip: Toss thawed frozen rhubarb with a spoonful of flour to soak up any extra liquid.

Variations

• Berry Add-ins: Fold in a handful of strawberries or raspberries for a softer tang and stunning color contrast.
• Nutty Crunch: Sprinkle chopped pecans or almonds over the top before baking for extra texture.
• Citrus Zest: A touch of orange or lemon zest mixed into the custard adds a bright, aromatic twist.
• Gluten-Free: Use your favorite gluten-free pie crust and swap flour for a 1:1 gluten-free flour blend.

How to Make Rhubarb Custard Pie

Step 1: Prep the Oven and Pie Shell

Heat your oven to 400°F. Place your unbaked pie shell on a baking sheet (it helps catch any bubble-over and makes transferring easier).

Step 2: Add Rhubarb

Scatter the chopped rhubarb evenly in your pie shell, ensuring every bite gets plenty of that tangy fruit.

Step 3: Make the Custard

In a medium bowl, whisk together the granulated sugar, eggs, heavy cream, flour, and salt until completely smooth and combined. No lumps! This will bake into a silky, luscious custard.

Step 4: Assemble

Pour the custard mixture over the rhubarb, covering it evenly.

Step 5: Bake

Place the pie in the oven and bake at 400°F for 10 minutes. Then, without opening the oven, lower the temperature to 350°F and continue baking for about 40 minutes more. The custard should be mostly set—look for the edges to be firm and the very center to have just a gentle jiggle.

Step 6: Cool

This is crucial! Let the pie cool completely before slicing. The custard continues setting as it cools, and slicing too early means a runny pie.

Pro Tips for Making the Recipe

• Dry Rhubarb Is Best: If you use frozen rhubarb, thaw and dry it thoroughly. Too much moisture can make the filling runny.
• Custard Clarity: Whisk the custard base until super smooth to avoid any cooked egg bits in your slice.
• Shield Your Crust: If the edges of your pie start to brown too quickly, gently cover them with a strip of foil for the last 15–20 minutes.
• Let It Chill: Resist slicing until completely cool—overnight is even better for clean pieces.

How to Serve

This pie is simply wonderful served on its own—just let that creamy-tart filling shine! But if you want to dress it up:

• A Dollop of Whipped Cream: Clouds of whipped cream are classic and will never steer you wrong.
• A Little Ice Cream: Vanilla or strawberry ice cream melts into the warm slice beautifully.
• Fresh Berries: Scatter extra berries on top for a burst of color and fresh sweetness.
• Glass of Dessert Wine or Tea: Perfect with a gentle sip of sweet wine or a cup of herbal tea for a cozy finish.

Make Ahead and Storage

Storing Leftovers

Cover any leftover pie loosely with plastic wrap or foil and keep refrigerated. It will stay fresh for up to 3 days—if it lasts that long!

Freezing

You can freeze the fully cooled pie. Wrap it tightly in plastic wrap and then foil. When ready to enjoy, thaw overnight in the refrigerator. For best texture, enjoy within one month.

Reheating

If you love warm pie, reheat individual slices in the microwave for 10-15 seconds. For a just-baked feel, pop the whole pie in a low oven (about 300°F) for 10-15 minutes.

FAQs

Can I use milk instead of heavy cream in the custard?
Using heavy cream is highly recommended for the most luscious, stable custard. Milk can work in a pinch but will give a lighter, less creamy texture and might set a bit softer.

How do I tell when the pie is done baking?
The outer edges should look set and slightly puffed, while the very center should still jiggle just a bit when you gently shake the pie. It will continue to set as it cools, so don’t wait for it to be completely firm in the oven.

Can I make this pie with frozen rhubarb?
Absolutely! Just make sure you thaw the rhubarb fully and pat it dry with paper towels. Tossing it with an extra spoonful of flour helps prevent a watery filling.

Is it possible to make this pie in advance?
Yes, and you should! The flavors mellow and blend beautifully as the pie chills. You can bake it a day ahead, let it cool completely, and refrigerate until ready to serve.
