Classic Rhubarb Custard Pie

Classic Rhubarb Custard Pie is the perfect treat to make after those stalks start sprouting up in the spring! Flaky layers of pie crust surrounding a sweet/tart filling giving you a perfect bite!

Rhubarb is one of the first plants to pop up from the ground in the early spring months. I remember when I was just starting out on my own, my cousin Michelle and I were living in her dad’s little brown farm house that was just across the road from where I grew up.

Along the outside shed there was an abundant amount of rhubarb just dying to be made into all kinds of treats. The first pie I made on my own was a Rhubarb Custard pie, homemade crust and all! I was all of 19 years old and when I served a piece to Nanny, her proclamation was “that was the best Rhubarb Pie I have ever eaten!” She proceeded to tell everyone going forward what an excellent pie maker I was.

Needless to say, I got my baking genes from my Nanny and Mom however as I got older I got a little lazier about wanting to put the effort into a pie crust. That laziness may have disappeared after the results I got with this Classic Rhubarb Pie!

My children grew up on Rhubarb Pie the same as I did and both of them love it just as much as I do. and my son Justin is the reason I am sharing this with you as he suggested I make it and post the recipe here on my blog.

It is a yearly treat that I hate to go without. I don’t have my own rhubarb anymore and what I do get is either bought at a local stand or given to me from my parents. This year I was lucky enough to get just enough rhubarb for one pie from my parents on my recent visit home.

Rhubarb has a lot of different varieties. Some stalks are more red and some are more green. The greener variety is the heartier variety which is what I received this year when I visited my parents. A lot of people think that the red stalks are “sweeter” however, that is not a correct assumption as there is no such thing as sweet rhubarb. Less tart maybe, but not sweet. Green stalks tend to be thicker whereas red stalks tend to be more tender and thinner. I like getting the red stalks because I do like the color better, but the green stalks work just as great in a recipe as the red, your product just doesn’t have the prettier color to it even though it is just as tasty!

I decided to experiment a little and go with shortening and butter. I do use Crisco for my solid shortening and I highly recommend that is what you use also as I believe it gives the best results. I also used salted butter for the crust and put a few little extra pats of butter on top of the pie before covering it with the top crust. This is a personal preference and you do not need to do it but I wanted to tell you since that is what I do no matter what kind of fresh fruit pie I make.

Are you a pie person? What is your favorite pie?

  • 1/4 teaspoon salt
  • 3 tablespoons granulated white sugar
  • 1/2 cup vegetable shortening
  • 4 tablespoons salted butter cold and cubed
  • 1/4 to 1/3 cup ice water

For the filling:

  • 1/4 teaspoon ground cinnamon

Do not over pulse. Add the ice water a little at a time, pulsing food processor a couple of times after each addition. Once dough begins to form into a ball remove from food processor and place on well floured surface (such as a pastry mat). Bring dough together to form a ball being careful not to handle dough too much. Divide dough into two pieces and flatten out into a circle. Roll dough out on a floured surface until about 10-11 inch circle in diameter. Place 1 circle in bottom of pie pan and form to shape. Place other disc of dough in refrigerator until ready to top the pie.

    I have to admit, I've never seen green rhubarb, but I know I would love a slice of that pie! It looks just perfect in every way! Rhubarb has quickly grown to be one of my favorite things about spring!
