I get my love for this old-fashioned classic strawberry rhubarb pie from growing up watching my grandmother make it. Grandma’s rhubarb pies were brimming with fresh rhubarb, and I couldn’t wait for them to come out of the oven. That sweet strawberry rhubarb pie filling would bubble through her golden brown buttery crust just begging for a scoop of vanilla ice cream.

I can usually get my hands on fresh strawberries, but when rhubarb season is here that means it’s time to pull out all the stops and serve it any way that I can. My Grandma’s strawberry rhubarb pie recipe is one of our very favorite pies. But I sure wouldn’t turn down my Mom’s Rhubarb Custard pie or a generous slice of Strawberry Rhubarb Bread topped with a sweet crunchy streusel and glaze.

Whether you get your strawberries and rhubarb from the farmers market, pick-your-own, or grab them at the grocery store make sure you get extra and make this easy strawberry-rhubarb pie recipe.

What is Rhubarb?

Rhubarb is such an interesting vegetable. The raw form of edible rhubarb is a lot like celery. The stalks of the plant are the only edible part and are most often baked in pies. Rhubarb is pretty tart so strawberries or other fruit and sugar provide a nice balance.

How to Choose Rhubarb

Purchase Rhubarb in the grocery store in Spring or Summer for the freshest flavor. In the U.S. the main producers have two growing seasons in April/May and June/July.

Look for rhubarb that is crisp and firm with shiny stalks between 12 and 18 inches in length.

Do not get rhubarb that is soft or limp or has visible blemishes. Check out these great tips for selecting rhubarb at the store.

Once you pick home-grown rhubarb, you will need to use it quickly as it can dry out fast. Don’t dice it until you are ready to use it. If you can’t use it right away, dice it up and freeze it in an airtight container to use later.

Why make this recipe for Strawberry Rhubarb Pie?

If you already love an easy strawberry pie, my Old-Fashioned Rhubarb Pie recipe is going to blow you away. The sweetness of the strawberries combined with the tartness of the rhubarb makes this the best Strawberry Rhubarb pie that I’ve ever made and my go-to recipe. This is a very traditional pie where I grew up and if you haven’t tried it, you’re in for a treat.

Strawberry Rhubarb Pie Ingredients

• Strawberries. Always pick the freshest, most ripe strawberries you can find. I prefer our local farmer’s market when they are available.
• Rhubarb. A tart vegetable that looks a lot like celery. Rhubarb stalks can be green, red, or a combination of both.
• Sugar. White Granulated Sugar
• Ground Cinnamon – Just a small amount. This is optional.
• Cold Butter. I typically use salted butter in this recipe.
• Pie Crusts. We made a top and bottom crust using our all-butter homemade pie crusts. This pie would be beautiful with a lattice crust. You can use a store-bought pie crust as well.
• Egg. Whipped with water to use as an egg wash.
• Turbinado Sugar. A coarse sugar to top the pie crust with a nice crunch.

How to Make Strawberry Rhubarb Pie

It’s a super easy strawberry pie to make, especially if you buy your pie crusts already made!

1. Preheat your oven to 350º first so it gets nice and hot.
2. Slice the strawberries and the stalks of rhubarb into even thicknesses. There’s no need to peel rhubarb. Just remove the leaves and the white portion on the other end if it wasn’t removed before you got it.
3. Mix the first five ingredients (strawberries, rhubarb, sugar, cinnamon, and butter) in a medium bowl.

4. Place the bottom crust in your pie pan.
5. Add the fruit filling.

6. Cut the cold butter into small pieces and put it randomly over the top of the filling.

7. Top with the second pie crust.

8. Whisk the egg and 1 teaspoon of water together in a small bowl until foamy to make an egg wash.

9. Brush the top of the pie crust with the egg wash and quickly sprinkle with the turbinado sugar before the egg wash dries.

10. Make 4 to 6 slits with a sharp knife in the top crust so the steam can escape.
11. Bake at 350°F for 1 hour to 1 hour and 10 minutes or until golden brown and bubbly.

Tips for a Great Rhubarb Strawberry Pie

• Use fresh rhubarb for your old-fashioned Rhubarb Pie. This will ensure that your pie will not be watery. You can use frozen rhubarb but make sure it is completely thawed and press any excess liquid out of it. Too much water will cause your pie to have a soggy bottom.
  • This pie doesn’t require thickeners such as ground tapioca or corned starch. If you end up with a juicy pie it may be from underbaking.
• We put our unbaked pie on a parchment paper-lined baking sheet to prevent it from bubbling over in the oven. It also makes removing the pie from the oven easier.
• Place a pie shield or strips of aluminum foil over the edge of the pie plate during the last 10 minutes if the pie is becoming excessively brown.
• If you make this pie gluten-free using a gluten-free pie crust.
• Many egg washes use only egg whites, but I’ve found the crust browns more golden by using both.
• If the egg wash dries, the coarse sugar will not stick. Put it on right away for a delicious crunch and texture.
• Keep your pie dough cold and roll it out right before you need it. Or roll it out and cover it with plastic wrap in the refrigerator. If your crust is at room temperature or too warm becomes soft making it hard to crimp edges.
• What eggwash I have left I cook up for my pup. She loves it.

Storing and Freezing Your Pie

You can keep a rhubarb strawberry pie recipe for several days. We prefer to refrigerate it which will help to keep the juices from running out of the pie and becoming soggy.

You can freeze the whole pie by tightly wrapping it in plastic wrap and placing the pie in an air-tight container to keep for up to three months in the freezer. I like to freeze pies by the slice. That way none goes to waste when you only need one or two pieces.
