Savor the tangy sweetness of rhubarb in this easy, delightful crustless custard pie that will wow your taste buds! There’s no crust to fuss over—just pure, unadulterated flavor where the custard itself forms a gentle, custardy embrace around those vibrant ruby-red stalks. The balance of tart and sweet in this pie reminds me of spring afternoons spent in the garden, where each rhubarb stalk I snip has its own story to tell. With minimal prep and a single dish to wash, this recipe is the definition of beginner-friendly magic that elevates any dessert table with bright pops of pink and an aroma of warm vanilla and milk.

This crustless rhubarb custard pie features a creamy filling with a perfect balance of tartness and sweetness, all without the fuss of a crust.

After a 30-minute rest (and a bit of patience), you’ll slice into a custard that’s set just right, neither too firm nor too wobbly. At roughly 300 calories a slice, it’s a guilt-friendly dessert that can be enjoyed warm, straight from the oven, or chilled for a cool, refreshing finish. Whether you’re hosting a spring brunch, craving a simple after-dinner treat, or just looking to try something new, this pie is your new best friend in the kitchen.

KEY INGREDIENTS IN CRUSTLESS RHUBARB CUSTARD PIE

Before you dive in, let’s talk about the stars of this show. Each ingredient brings its own personality and purpose, coming together to create a custard pie that’s creamy, tangy, and perfectly set.

  • Rhubarb

Known for its bright color and tart flavor, rhubarb provides that signature tang. As it bakes, it softens and releases just enough juice to infuse the custard with refreshing acidity.

  • Eggs

The backbone of any custard, eggs act as a binder and give the filling its silky texture. Whisked thoroughly, they help the mixture set into a tender, sliceable custard.

  • Granulated sugar

Sweetens and balances the tartness of the rhubarb. Sugar also contributes to the custard’s smooth structure by helping proteins coagulate evenly.

  • All-purpose flour

A bit of flour thickens the mixture and ensures the custard holds together as it bakes. It prevents the filling from becoming too loose or soupy.

  • Vanilla extract

Adds warm, fragrant notes that elevate the custard’s flavor profile. A teaspoon goes a long way in creating depth and complexity.

  • Salt

Enhances all the flavors and prevents the custard from tasting flat. Salt sharpens the sweetness and ensures the custard isn’t overly cloying.

  • Whole milk

Brings richness and creaminess to the custard. Its fat content yields a luscious mouthfeel without being too heavy.

  • Butter

Used to grease the pie dish, melted butter prevents sticking and lends a hint of buttery aroma around the edges of the pie.

HOW TO MAKE CRUSTLESS RHUBARB CUSTARD PIE

Now that you’ve gathered your ingredients, it’s time to transform them into a stunning crustless pie. Follow each step carefully, and don’t rush—custards thrive on gentle handling and precise baking.

1. Preheat your oven to 375°F (190°C), ensuring it reaches temperature before your pie goes in. A consistent oven heat helps the custard bake evenly and set properly.

2. Wash and chop the rhubarb stalks into small pieces, roughly ½ inch thick, so they cook through without turning to mush. Set them aside while you mix the custard base.

3. In a large mixing bowl, whisk together the eggs and granulated sugar until the mixture is smooth and pale. This aerates the eggs and dissolves the sugar, which is essential for a silky custard.

4. Gradually add the flour, continuing to whisk until no lumps remain. A lump-free batter is key to achieving a uniform texture in the final pie.

5. Stir in the vanilla extract and salt, mixing until they’re fully incorporated. This step ensures the flavor compounds are evenly distributed.

6. Slowly pour in the whole milk, whisking constantly to maintain a smooth consistency. This keeps the custard base from separating or curdling.

7. Gently fold the chopped rhubarb into the custard mixture, using a spatula to avoid overmixing. Even distribution of rhubarb ensures each slice has a perfect balance of fruit and custard.

8. Grease a 9-inch pie dish with the melted butter, ensuring it’s evenly coated to prevent any sticking. A thin, even layer of butter also adds a subtle richness around the crust edges.

9. Pour the rhubarb custard mixture into the prepared pie dish, smoothing the top gently with a spatula.

10. Bake in the preheated oven for 50–60 minutes, or until the custard is set and the top turns lightly golden. To check doneness, insert a toothpick into the center—it should come out clean. If the top browns too quickly, tent with aluminum foil.

11. Allow the pie to cool for at least 30 minutes before serving. As it cools, the custard firms up, making it easier to slice and serve.

SERVING SUGGESTIONS FOR CRUSTLESS RHUBARB CUSTARD PIE

When it comes to presenting this crustless marvel, you have a world of delightful options that showcase its vivid color and creamy texture. Whether you prefer classic simplicity or want to elevate each slice with a decorative flourish, these serving ideas will ensure every bite is as beautiful as it is delicious.

  • Serve each slice warm with a light dusting of powdered sugar. The warmth brings out the custard’s creamy depth, and the sugar adds a delicate sparkle.
  • Plate chilled slices alongside a generous scoop of vanilla ice cream. The contrast of cold, creamy ice cream against the tangy custard creates an irresistible combination.
  • Add a dollop of fresh whipped cream and garnish with thin rhubarb ribbons. The airy texture of whipped cream complements the custard’s silkiness, while the ribbons add visual interest.
  • Drizzle a vibrant berry coulis around each slice and top with fresh mint leaves. The coulis echoes the fruitiness of the rhubarb, and mint adds a refreshing finish.

HOW TO STORE CRUSTLESS RHUBARB CUSTARD PIE

Storing this pie properly ensures it remains luscious and flavorful for days to come. Whether you plan to enjoy leftovers or make it in advance for a gathering, these tips will help you maintain the custard’s texture and the rhubarb’s brightness. Remember, temperature control and airtight protection are your best friends in preserving freshness.

  • Wrap slices tightly in plastic wrap and place them in the refrigerator. This prevents the custard from drying out and keeps it at a safe temperature for up to 3 days.
  • Store the entire pie in an airtight container or cover it with aluminum foil to guard against absorbing other fridge odors. Proper coverage helps retain moisture and flavor.
  • For longer storage, slice the pie and freeze individual portions wrapped in freezer-safe foil and placed in a sealed plastic bag. Label with the date—they’ll keep well for up to one month.
  • Thaw frozen slices overnight in the refrigerator, then let them come to room temperature or warm gently in a low oven for about 10 minutes before serving.
