If you’re looking for an amazing, no-nonsense Rhubarb Pie, you’ve come to the right place! It’s so simple to make with only six ingredients, and will please the most critical Rhubarb Pie enthusiasts!

How to make Rhubarb Pie:

Combine sugar, tapioca flour, and zest in large mixing bowl. Add rhubarb and toss to coat.

Chopped rhubarb tossed in flour, tapioca starch and lemon zest.

Prepare Pie Crust: Place unbaked pie crust in pie plate. Sprinkle 1 tablespoon coarse sugar over the bottom of the pie crust, to help keep it from getting soggy. Pour rhubarb mixture into pie pan. Cut butter into small pieces and dot over the top of the rhubarb filling.

Rhubarb pie filling added to the bottom of an unbaked pie shell.

Roll out second pie crust and place on top. Trim, seal and flute edges and cut a few slits (a small X) on top to allow air to escape.

Bake at 400 degrees F for about 1 hour (tent the top of the pie loosely with aluminum foil part way through cooking to keep the crust from browning too much).

Cool for at least 4 hours before serving. Refrigerate for up to 4 days.

Make Ahead and Freezing Instructions:

To Make Ahead: This pie can be made ahead and refrigerated for up to 4 days. The homemade pie crusts can also be made ahead and stored in the fridge or freezer. Follow my instructions HERE.

To Freeze: Bake the pie and allow it to cool completely.  Cover well with plastic wrap as well as tinfoil. Store in the freezer for up to 3 months.  To thaw, place it in the refrigerator for about 1 ½ days.

    There is nothing better than a fresh rhubarb pie. Making this brought me back to the times I would make this with my grandparents from rhubarb right from their garden all those years ago. This is my go-to recipe!
