Gluten Free Rhubarb Pie
Yes, indeed! Here is a straight up, Gluten Free Rhubarb Pie Recipe – sweetly tart, just as it should be. This is good news for the purists our there. We have a mighty rhubarb plant growing in our back yard. Wow, this plant loves where it lives! Truly, our majestic rhubarb rules the grounds around here. Lucky for us, our family loves rhubarb pie.

Sweetly Tart with the Perfect Pie Crust
We honestly do not have an easier way to simply serve pie than to this whip up this recipe. We sprinkle sugar on top of the fruit just before adding the top layer to maintain a crispy crust. No soggy bottoms or tops allowed in this kitchen! We have two easy-peasy pie crusts to choose from: Flaky or Tender. Click on the respective links to check them out. The tender pie crust is our personal choice for rhubarb pie; however, if you are adverse to dairy, the flaky recipe is easier to adapt or to make vegan.

Before You Dive In – Prep: Please read!
- Prepare 1 batch of our GF Flaky or Tender pie crust recipes, makes both a top/bottom crust (or store purchased ready to bake GF crusts)
- Slice clean and dried rhubarb stalks
- Grind instant tapioca in a spice grinder or processor if granules are pearly
- Move oven rack to lower third position
- Preheat oven to 425 degrees Fahrenheit (220 C)
- Butter or apply non-stick spray to the pie dish (try our non-stick Goop)
- Make a pie crust shield if using (Here is a great tutorial to make your own, and we think it works better than purchased shields.)
Make Pie!
Step 1: Remove prepared pie dough disks from the refrigerator and let it sit on the counter for up to an hour. The dough should be soft enough to roll out, but stiff enough to provide a bit of resistance when pressed. Roll out each disk using a pie crust bag or between unbleached parchment or cling wrap to make your life easier! If the dough feels a bit tacky, lightly dust the rolling surface and surface of disk with flour. Roll dough about 1″ (2.5 cm) larger than the circumference of the outer rim of your pie dish. Do not remove rolled dough from bag or remove sheets of parchment. Place dough on rimless baking sheets and return to the refrigerator for 15 minutes. You can do this make-ahead step one day in advance.
Step 2: Remove bottom crust from the refrigerator and check for pliability. If it feels very stiff, allow it to sit for about 5-10 minutes to soften up. Gently remove the crust from the bag or parchment and place in the pie dish. Press the dough into place. Be mindful to press out any air pockets. Allow the edge to hang over or along the rim. Return the dish to the refrigerator until you are ready to fill. It does not need to be covered.
Step 3: Remove the top crust from the refrigerator. Set aside.
Step 4: In a large bowl, combine the rhubarb, 2 T of cane sugar, tapioca, and cardamom. Stir to combine and set aside.
Step 5: Remove the pie dish from the refrigerator and sprinkle 2 T of cane sugar evenly on the bottom of the crust. Pour the rhubarb mix into the dish, and smooth out. Dot the surface with diced, cold butter. Sprinkle the remaining 1/2 C sugar evenly over the top.
Step 6: Remove the top crust from the pie bag or parchment and place on the pie. Pinch the edges of the two crusts together – do not wet edges! Liquid prevents the edges from sealing. Press the edge into your desired shape using your fingers or edge cutting tool. If you use a tool, make sure the dough is cool enough. You may have to put the pie in the refrigerator for a few minutes. A tool does not work well with warm dough.
Step 7: Brush the cream onto the surface of the pie with a pastry brush. Sprinkle the 1 T of sugar evenly over the top. Cut vents into the surface and a small decorative hole in the middle. The hole lets you know if the middle of the pie is bubbly. Place a pie crust shield gently along the rim. Remember to remove the shield about 5 minutes before the pie is ready.
Step 8: Place the pie in a preheated 425 F/220 C oven on the lower third rack. Bake for 15 minutes. Reduce the heat to 350 F/177 C and continue to bake for 1 hour. The pie is ready when the middle is bubbly. This sign tells you that the tapioca has had enough time to do its job.
Step 9: Remove the pie from the oven and allow to cool on a wire rack. The filling will continue to firm up as it cools, and will actually be perfectly set the next day. Who can wait that long? Serve warm with ice cream on the side.
Enjoy!
Notes
To store: Rhubarb pie actually tastes the best the day after baked. You can leave it out overnight covered with foil after it has completely cooled. If not eating within one day, refrigerate covered for up to three days.
Frozen Fruit: If you have frozen rhubarb, keep the fruit frozen and add 1.5 tsp of tapioca.
Strawberry Rhubarb: Add two cups of cut strawberries and an additional 1.5 T of tapioca.
