Easy Strawberry Rhubarb Pie with a Buttery Crumb Topping

Is there anything more wonderfully American than a homemade pie cooling on the windowsill? Well, maybe one that skips the fuss of a lattice top and gets straight to the good stuff: a buttery, crunchy, sweet crumble that you just sprinkle right on. That’s the magic of this Strawberry Rhubarb Pie with Crumb Topping. It gives you that iconic sweet-tart filling and flaky crust, but the method is so much friendlier for a busy weeknight. No fancy weaving required!

Why You’ll Love This

You get all the classic flavor of a strawberry rhubarb pie but with a fraction of the effort. The crumb topping is my favorite part—it’s buttery, it’s crunchy, and it’s impossible to mess up. This recipe is also incredibly forgiving. A little more strawberry? Great. A little less rhubarb? It will still be delicious. It’s the perfect dessert to whip up when you need a taste of sunshine and a major win. So good.

Equipements Needed

  • 9-inch pie plate (glass or ceramic is best for a crisp crust)
  • Large mixing bowls (one for filling, one for topping)
  • Pastry cutter or your fingertips (for the crumb topping)
  • Rolling pin
  • Wooden spoon or spatula
  • Measuring cups and spoons

Ingredients

For the Filling:

  • 3 cups fresh rhubarb, sliced into 1/2-inch pieces (brings the signature tartness)
  • 3 cups fresh strawberries, hulled and halved (for sweetness and juicy texture)
  • 3/4 cup granulated sugar (balances the tart rhubarb)
  • 1/4 cup light brown sugar (adds a subtle molasses depth)
  • 1/4 cup cornstarch (the key thickener for a perfect sliceable filling)
  • 1 teaspoon vanilla extract (enhances all the other flavors)
  • 1/2 teaspoon orange zest (brightens everything up)
  • 1/4 teaspoon salt (makes all the flavors pop)

For the Crumb Topping:

  • 1 cup all-purpose flour
  • 1/2 cup light brown sugar
  • 1/2 cup old-fashioned rolled oats (for extra texture and crunch)
  • 1/2 cup (1 stick) unsalted butter, melted (binds it all and creates that crave-worthy crispness)
  • 1/4 teaspoon salt

For the Crust:

  • 1 store-bought or homemade pie crust, fitted into your 9-inch pie plate

Step By Step

  1. Preheat your oven to 400°F (200°C). Place a baking sheet on a lower rack to catch any potential drips—trust me, you’ll thank yourself later!
  2. Make the filling: In your large bowl, gently toss the sliced rhubarb and strawberries with the granulated sugar, brown sugar, cornstarch, vanilla extract, orange zest, and salt until everything is evenly coated. Let it sit for 15 minutes. You’ll see a lovely syrup start to form.
  3. Make the topping: In a separate bowl, whisk together the flour, brown sugar, oats, and salt for the crumb topping. Pour in the melted butter and stir with a fork until the mixture is completely moistened and crumbly.
  4. Assemble the pie: Pour the fruit filling (and all those juices) into your unbaked pie crust. Spread it into an even layer. Sprinkle the crumb topping evenly over the entire surface of the fruit, covering it completely.
  5. Bake: Place the pie on the preheated baking sheet and bake for 20 minutes at 400°F. Then, without opening the door, reduce the oven temperature to 350°F (175°C) and continue baking for another 35-45 minutes. The pie is done when the filling is thick and bubbly all over and the crumb topping is a beautiful golden brown.
  6. Cool: This is the hardest part! You must let the4 hours. This allows the filling to set properly so you get clean slices instead of a soupy mess. Honestly, it’s worth the wait.

Oven Temperatures

This pie starts hot to set the crust and then finishes at a lower temperature to cook the filling through without burning the topping. The initial 400°F blast gives the bottom crust a head start, preventing a soggy bottom. The drop to 350°F is the sweet spot for gentle, even cooking that results in tender fruit and a perfectly thickened filling quickly, you can lay a small piece of foil loosely over the top.

Variations & Substitutions

  • Vegan: Use your favorite vegan pie crust. For the topping, use vegan butter and ensure your sugar is vegan-friendly.
  • Nutty Twist: Add 1/3 cup of chopped pecans or walnuts to the crumb topping mixture for extra crunch.
  • Spiced: A dash of cinnamon or cardamom (about 1/2 teaspoon) in the filling adds a lovely warm note.
  • Short on Fruit? You can use all frozen fruit—no need to thaw! Just toss it directly with the sugar and cornstarch. You may need to add 5-10 minutes to the baking time.

Serving Ideas & Pairings

This pie is an absolute dream served slightly warm with a generous scoop of vanilla ice cream. The combination of warm, tart filling and cold, creamy sweetness is simply the best. For a decadent brunch, serve a slice with a dollop of freshly whipped cream. And for a true classic, a sharp white cheddar cheese slice alongside a piece of pie is a surprisingly delicious pairing that really works.

Storage & Reheating

Cover any leftover pie loosely with foil or plastic wrap and store it at room temperature for up to 2 days. For longer storage, keep it in the refrigerator for up to 4 days. The crust and topping will soften a bit, but it will still taste amazing. To reheat a single slice and bring back that fresh-from-the-oven crispness, pop it in a 350°F oven or toaster oven for about 10 minutes. You can also freeze the baked and cooled pie for up to 3 months. Thaw it overnight in the refrigerator before reheating.

Frequently Asked Questions

  • Do I need to peel the rhubarb? Nope! Just give it a good wash and trim off the leaves and the very bottom of the stalk. The skin is totally edible and helps the pieces hold their shape.
  • Can I make this strawberry rhubarb pie recipe ahead? Absolutely. You can prepare the filling and store it in the fridge for a day, and mix the crumb topping and keep it in a separate bag in the fridge. Assemble and bake the day you want to serve it for the freshest, crispiest results.
  • My filling is too runny. What happened? This usually means the pie needed more time to cool. The cornstarch needs that full cooling time to reach its full thickening power. Also, make sure you’re using cornstarch and not flour for the thickener, as it creates a much clearer, glossier filling.
