Ingredient Notes and Substitutions

Rhubarb: Fresh rhubarb gives the best flavor and texture. If using frozen rhubarb, thaw it fully and drain excess liquid to avoid a watery filling.

Sugar: White sugar is best for a classic flavor. You can reduce slightly if you prefer a more tart pie.

Flour: Helps thicken the filling so it is not runny. Cornstarch can be used instead if needed.

Butter: Adds richness and helps create a smooth, flavorful filling.

Pie crust: Store-bought crust works well, but homemade crust gives a more flaky and buttery result.

Egg wash: Helps the crust turn golden brown and slightly glossy.

Step-by-Step Instructions for Homemade Rhubarb Pie

Step 1: Prepare the Oven and Pie Dish

Preheat the oven to 425 degrees Fahrenheit.

Place one pie crust into a 9-inch pie dish. Press it gently into the bottom and sides so it fits evenly. Trim any extra dough hanging over the edges.

---

Step 2: Prepare the Rhubarb Filling

Wash and chop the rhubarb into small, even pieces. This helps it cook evenly in the oven.

In a large mixing bowl, combine sugar, flour, and salt. Stir well so everything is evenly mixed.

Add the chopped rhubarb into the bowl and toss until every piece is coated with the sugar mixture. The flour helps absorb the juices while baking so the filling stays thick.

---

Step 3: Fill the Pie Crust

Pour the rhubarb mixture into the prepared pie crust. Spread it evenly so it fills all corners of the dish.

Cut the butter into small pieces and place them evenly over the filling. This helps create a rich and smooth texture while baking.

---

Step 4: Add the Top Crust

Place the second pie crust over the filling. Gently press the edges together with the bottom crust to seal it.

Trim excess dough and crimp the edges using your fingers or a fork. This helps keep the filling inside while baking.

Cut several small slits in the top crust. These allow steam to escape so the filling does not bubble over.

---

Step 5: Apply Egg Wash

In a small bowl, whisk the egg with one tablespoon of water.

Brush this mixture over the top crust using a pastry brush. This gives the pie a shiny golden finish when baked.

---

Step 6: Bake the Rhubarb Pie

Place the pie in the preheated oven at 425 degrees Fahrenheit and bake for 15 minutes.

Then reduce the oven temperature to 350 degrees Fahrenheit and continue baking for 40 to 45 minutes.

The pie is done when the crust is golden brown and the filling is bubbling through the slits.

---

Step 7: Cool Before Serving

Remove the pie from the oven and let it cool for at least 2 hours.

This step is very important because it allows the filling to thicken and set properly. Cutting too early may cause the filling to run.
