Plus it is low carb with just a bit of flour friendly.

Impossible Pies. There is no pie crust to roll out with this recipe. Bake the rhubarb in a custard and let the magic happen. This is a perfect pie to make during rhubarb season. My aunt has a rhubarb patch and we go and pick a bit there each season. She is only able to come home a few times throughout the year. My mom and I will pick some for her and freeze it in 2 cup portions so she can enjoy making something from her rhubarb patch when she is home.

We have to make this crustless pie at least once a year. I am not sure why we do not make it more often as it is such an easy recipe. This can be made with frozen rhubarb too. You just have to thaw and drain the liquid before proceeding with the rest of the recipe.

What Does Rhubarb Custard Pie Taste Like?

What is Rhubarb?

Rhubarb is a vegetable; however, it is often made into jams, pies, and other sweet confectionaries. Therefore, it can be confusing as it tastes more like a tart fruit in recipes.

This perennial plant sprouts out of the ground each spring with the sour stalks. The colors of the rhubarb stalks can range in color from pale green to deep red.

How to Harvest Rhubarb

Look forfirm, and crispstalks about 10-12 inches long with fresh-looking leaves. For the tenderest, sweetest stalks, look for firm young stalks that are less than 2 inches wide.

DO NOT eat the leaves as they are poisonous. Just the stalks are edible. The stalks that are smaller in diameter are much more tender and you do not have to peel the stalk.

When harvesting the rhubarb, pull it out so some of the root comes with it. This will tell the plant to grow more. Also, to keep the plant healthy do not harvest more than about 30 percent of the plant.

Snip off the root part of the stalk from the top of the rhubarb (the leaves), then place the stalks in a bag or other container to bring into the kitchen for making your recipe. Now all you have to do is give it a quick wash and dice.

Using Red Versus Green Rhubarb

The color of the rhubarb indicates what variety you are growing. However, for the most part, there is very little, if any flavor difference between the varieties. Therefore, you can safely use both the red and green rhubarb varieties for this pie recipe.

Can You Freeze Rhubarb?

Often, we have more rhubarb in the late spring of the year than we can eat. Therefore, we clean, dice, and freeze the extra rhubarb in plastic containers or freezer bags. Normally, about 2 or 3 Cups in each container.

We enjoy rhubarb recipes throughout the year adding the frozen rhubarb to whatever recipe we are making. It is best to use the rhubarb within six months of freezing.

Crustless Rhubarb Pie Ingredients

Butter Softened. This is used to prepare the pie plate.

How to Make This Rhubarb Custard Pie Recipe

Preheat oven to 375 degrees Fahrenheit.

Very generously grease the pie plate with softened butter on the bottom and sides of the pie plate. Clean and dice rhubarb and add the diced rhubarb to the pie plate.

Mix the Flour, Granulated sugar, Baking Powder, Salt, Eggs, Vanilla Extract, and Milk in a blender until well blended. Just a minute or two. Pour over rhubarb.

Bake for 40 minutes. When done, the center will be ever so slightly jiggly. That will firm up once removed from the oven and let sit for 10-15 minutes. Slice and serve.

Recipe Pro Tips

If the rhubarb stalk is a bit on the large side, peel off the outside. The outside layer on the larger stalks can be tough and even if you cook this longer, it really does not seem to soften enough to really enjoy in a pie. I just take part of the outside layer between a pairing knife and my thumb and gently pull it off in one long strip. Repeat around the stalk until you have the outer layer removed.

If it is on the smaller side, just go ahead and dice it up without peeling.

If you are using a deep dish pie, go ahead and use more rhubarb and custard to fill the pie shell up.

Bake the pie in a preheated oven.

This recipe is for 1 9-inch pie plate; however, you can make this in smaller custard tarts or individual pie tins. Check for doneness after 20-30 minutes of baking time. The total baking time should not be more than 40 minutes. However, each oven is slightly different for temperature variation.

It is better to use fresh rhubarb, but if you thaw frozen rhubarb and drain the liquid before adding it to the pie pan, then this can be made year round.

You can add a cup of fresh strawberries for a strawberry rhubarb pie. Raspberries work with this recipe if you want a bit more berry flavor. Adjust to your personal preference.

How Long will a No Crust Pie Last?

Make sure to eat this pie the day it is made or at least by the next day, as it will take on more of a custard texture rather than a pie texture.

However, this should be stored in the refrigerator covered in plastic wrap or an air tight container and it will last 2-3 days.
