Ingredients You’ll Need

Ingredients You’ll Need

This Crustless Rhubarb Custard Pie keeps things classic and unfussy, using wholesome ingredients that let the rhubarb’s personality shine. Each component matters, combining for a creamy texture, gentle sweetness, and that signature tart kick.

• Soft butter: Ensures a rich flavor in the custard and also helps create a beautifully golden “crust” along the sides and bottom.
• Fresh rhubarb: Sliced thinly so it softens into tangy, jewel-toned bites—be sure to measure for about 3 cups.
• Large eggs: These are the backbone of the custard, lending body, silkiness, and a slight lift as the pie bakes.
• Milk: Adds creaminess and prevents the custard from becoming too dense—whole milk is ideal, but 2% works too.
• Sugar: Evaporated cane sugar is lovely, but any granulated sugar will balance the rhubarb’s tartness.
• Flour: Classic all-purpose for structure, or a gluten-free blend plus rice flour for a tender, gluten-free crumb.
• Pure vanilla extract: Brings warmth and depth that lingers delightfully in every bite.
• Ground nutmeg (optional): A hint of spice that plays beautifully with the custard’s creaminess.

How to Make Crustless Rhubarb Custard Pie

Step 1: Prep Your Oven and Pan

Start by preheating your oven to 350°F (180°C). Generously grease your pie pan with about a tablespoon of the soft butter, making sure to cover every nook so you get those lovely golden edges. A 9-inch deep-dish pie pan is perfect, but you can also use a square baking dish in a pinch!

Step 2: Get the Rhubarb Ready

Slice your rhubarb stalks into 1/4-inch pieces for an even, tender texture. Spread the sliced rhubarb evenly in the buttered pan—this will be the vibrant base of your Crustless Rhubarb Custard Pie, bubbling up with color as it bakes.

Step 3: Blend the Custard

Pop the eggs, milk, sugar, flour, vanilla, and optional nutmeg into your blender canister. Melt the remaining butter and let it cool for a minute, then pour it in with the others. Blend it all on medium speed for 1 to 2 minutes, until the batter is gorgeously smooth and pale.

Step 4: Combine and Pour

Pour the custard mixture right over the rhubarb in the pan. If any pieces try to float, just press them down gently so they’re tucked beneath the batter’s surface. This ensures an even bake and those beautiful layers once the pie is sliced.

Step 5: Bake to Perfection

Slide your pan into the oven and bake for 45 to 50 minutes. You’re looking for a deeply golden top that’s puffed all over and a gentle wobble in the center. The magic happens while it cools: that clever “crust” forms and the custard sets to silky perfection.

Step 6: Cool and Serve

Let the pie cool completely on a wire rack so it slices cleanly. Cut into wedges (6 or 8 depending on your crowd) and decide whether you like yours at room temperature or with a little chill from the fridge—both are dreamy!

How to Serve Crustless Rhubarb Custard Pie

Garnishes

Dress up your Crustless Rhubarb Custard Pie with softly whipped cream or vanilla ice cream for extra indulgence. A sprinkle of powdered sugar or a few scattered fresh raspberries also makes every slice look bakery-worthy. If you’re feeling fancy, a little grated lemon zest perks up the rhubarb’s tartness.

Side Dishes

Pairing is personal, but a cup of hot tea or freshly brewed coffee alongside a warm or cool slice elevates things effortlessly. Try it with a crisp salad for brunch, or serve as the grand finale after a roast chicken dinner—sweet and creamy always plays well against savory!

Creative Ways to Present

For casual gatherings, cut the pie into squares and serve on a platter—everyone loves finger-friendly treats. Hosting a celebration? Layer generous wedges with whipped cream in glass jars for a playful “pie parfait.” Even a single slice with a sprig of mint feels special enough for company.

Make Ahead and Storage

Storing Leftovers

Cover any leftover Crustless Rhubarb Custard Pie tightly with plastic wrap or transfer to an airtight container. Left out on the counter, the custard dries too quickly, so a spot in the refrigerator keeps it lusciously creamy for up to 3 or 4 days.

Freezing

Yes, you can absolutely freeze slices! Wrap each slice in plastic, then foil, and tuck them into a freezer-safe bag. They’ll keep well for up to 2 months. Thaw overnight in the refrigerator before serving to enjoy that custard texture.

Reheating

While this pie is delightful cold or at room temperature, if you like your desserts slightly warm, pop a slice in the microwave for about 10–15 seconds. Or reheat in a low oven (300°F/150°C) for a few minutes—just until gently warmed through, not cooked further.

FAQs

Can I use frozen rhubarb for this pie?

Definitely! Just thaw and drain the rhubarb well to remove excess moisture before slicing and adding to your pan. This helps prevent the custard from turning watery.

How do I make this recipe gluten-free?

It’s easy to make a gluten-free version: simply swap in a half-and-half combo of gluten-free flour blend and white rice flour (or all gluten-free blend). The result is still perfectly set, with just the right bite.

Why did my pie separate into layers?

That’s actually part of the magic! The batter settles as it bakes, so the base gets a little “crust-like,” the custard forms the silky middle, and the rhubarb decorates the top—each bite is delightfully layered by design.

Can I use other fruits in place of rhubarb?

Sure! Tangy fruits like raspberries or blueberries work well, or even stone fruit like plums. If you swap, you may want to adjust the sugar slightly and skip the nutmeg depending on your chosen fruit.

What if I don’t have a blender?

No worries—a good whisk and some elbow grease will do the trick. Mix everything until smooth and combined, making sure to eliminate any lumps in your flour before pouring over the rhubarb.

Final Thoughts

If you’re looking for a fresh spin on a classic spring dessert, this Crustless Rhubarb Custard Pie is nothing short of delightful.
