Servings: 8 people


  • 1 uncooked gluten free pie crust
  • 3 cups raw or thawed, drained and dried rhubarb medium pieces
  • 1 ¼ cup sugar
  • 3 eggs beaten
  • 1 cup full fat unsweetened coconut milk use fat off top first
  • 3 tbsp gluten free flour
  • ½ tsp gluten free vanilla
  • ½ tsp salt


  • Preheat oven to 400°F
  • Put rhubarb in uncooked pie shell.
  • In a mixing bowl, mix the remaining ingredients.
  • Pour over rhubarb in pie shell.
  • Bake 10 minutes, then reduce heat to 350°F and bake for an additional 40-50 minutes. Or until a knife comes out clean.
  • Let the pie cool completely before serving. Store in refrigerator for up to 4 days.


If you are using frozen rhubarb, you can thaw it, drain it and pat it dry. Add it to your uncooked pie crust and add an extra tablespoon of your favorite gluten-free flour.

Pie Crust: I really love both a flakey gluten-free pie crust or a gluten-free graham cracker crust. They both offer different wonderful textures to the Rhubarb Custard Pie. Normally, I use a graham cracker crust, just because they are easier to find at our grocery store.

If you are using a flakey dough crust for your rhubarb pie, you will want to add tin foil to the edges after about 20 minutes of cooking. Or a pie crust protector shield (pictured above). Then, it won’t over brown.

In addition, you can find my Strawberry Rhubarb Oatmeal Bake recipe for a great make-ahead breakfast!

  1. I would love to try this recipe. You say use the fat off the top first from the coconut milk. Do you mean that you have to put the cans in the fridge overnight to get the cream part only and not the liquid? I also have a can of coconut cream – so I could use that.

    1. Hello Christine! I do not chill my coconut milk beforehand… I just grab the fatty thick part of the coconut milk that separates in the can, or you can use coconut cream. Either way!! Enjoy 🙂
