Rhubarb Rosemary Streusel Pie

I’ve been waiting my WHOLE LIFE to share this recipe with you.

Rhubarb Rosemary Streusel Pie

Okay, a year. But it feels like a lifetime because a year ago we were entirely different people living entirely different lives.

We could leave our houses!! Without masks!! Or lysol spray!!

What crazy, weird, reckless people we were back then.

Rhubarb Rosemary Streusel Pie

What day is it? What month are we in?


I’ve actually been on a hunt for it (and by that I mean that I scour all the online delivery services for it on a weekly basis) and it has been impossible to find. I actually remember this being true in my BC (before corona) life as well, but back then I could just run to the corner store and pick some up.

Now I’m left sending frantic (definitely NOT annoying) messages to my Amazon Prime Now shopper who basically ignores all of my pleas/requests.

Rhubarb Rosemary Streusel Pie

I tip well, I swear.

Basically, this is my way of saying don’t feel bad if you can’t find rhubarb. I can’t either!!

But maybe someday we’ll meet again and when we do I’ll absolutely definitely be RUNNING to make this pie because it is fricking glorious.

The filling is made of just rhubarb, (lots of) sugar, and a hint of ginger spice. It’s beautifully sweet-tart and sets up absolutely perfectly. It’s topped with a slightly herbal streusel that ties the whole thing together and will make you wonder why you haven’t been eating rosemary with your rhubarb your whole life.

Yield: 8 servings
For the crust
  • 2½ cups all purpose flour
  • 1 tsp sugar
  • 1 tsp kosher salt
  • 1 cup unsalted European-style butter, cut into ½-inch cubes
  • ½ cup ice
  • 1 cup ice water
  • 2 tbsp apple cider vinegar
For the rosemary streusel
  • ¾ cup (90 g) all purpose flour
  • ¼ cup (30 g) whole wheat flour
  • ½ cup (100 g) packed light brown sugar
  • 2 tsp finely minced fresh rosemary
  • ¼ tsp kosher salt
  • ½ cup (113 g) unsalted butter, chilled and cut into ½-inch cubes
For the filling
  • 1¾ lb (790 g) rhubarb, trimmed and sliced into 1-inch pieces
  • ¾ cup (150 g) sugar
  • ¼ cup (50 g) turbinado sugar
  • ¼ cup + 2 tbsp (40 g) tapioca starch
  • ⅛ tsp ground ginger
  • ¼ tsp kosher salt
  • ¼ tsp lemon zest
  • 1 large egg, beaten
For the crust
  1. Whisk together the flour, sugar, and salt in a large bowl. Add the cold butter cubes and toss so that they are coated with the flour. Using a pastry blender, cut the butter into the flour until the largest butter pieces are the size of peas. The rest of the mixture should look and feel like Parmesan cheese.
  2. Place the ice in a liquid measuring cup. Add ice water until it reaches the 1 cup mark, then stir in the apple cider vinegar.
  3. Add the ice water-vinegar mixture to the pie crust mixture by the tablespoon, mixing with your hands, until the dough comes together. Remove it from the bowl and cut it into two equal pieces. Pat each piece into a 2-inch thick disc, wrap in plastic wrap, and refrigerate for at least 2 hours or overnight. (This makes enough for two single crust pies or one double crust pie, so freeze any unused discs. This recipe only uses one.)
  4. Once chilled, roll the dough into a 13-inch round on a floured surface. Fit into a pie plate and crimp as desired. Freeze the crust for 15 minutes.
  5. Heat oven to 450F. Remove the pie crust from the freezer and line with aluminum foil. Fill with dried beans or pie weights and place in the oven on a baking sheet. Bake for 25-27 minutes. Fold back the foil, exposing the crimps. Bake for another 5-7 minutes, or until the crimps are a deep golden brown.
  6. Remove from the oven and let cool while you prepare the filling.
For the streusel
  1. Combine the flours, brown sugar, rosemary, and salt in a large bowl. Cut the butter into the flour mixture, using your fingers or a pastry blender. Continue to break down the butter until the mixture resembles wet sand. Place in the refrigerator until ready to use.
For the filling
  1. When ready to bake the pie, heat oven to 350F. Line a baking sheet with parchment paper. Set aside.
  2. In a large bowl, toss together the rhubarb, sugars, tapioca starch, ginger, salt, and lemon zest until evenly mixed.
  3. Brush the crimped edge of the pie crust with the beaten egg. Layer the rhubarb mixture on top of the pie crust in an even layer. Cover with the streusel topping, leaving a hole in the center to vent it. Place the assembled pie on the prepared baking sheet.
  4. Place in the oven and bake for 1.5-2 hours, or until the pie juices are bubbling in the center and the streusel is a deep golden color.
  5. Allow to cool completely before serving.

    This looks so wonderful!!! I seriously burst into tears the other day when my Whole Foods order arrived and it didn’t have the rhubarb I’d ordered (which was the only reason why I even placed an order in the first place)! Thankfully, my mom reached out to her gardening contacts and I was able to swap a batch of chocolate chip cookies for some rhubarb! Hope you are able to have rhubarb success soon!

    I think I can get rhubarb pretty easily. Mostly because I think people don’t know what to do with it so they’re not hoarding it like sugar, cornmeal, or… buttermilk.

  3. This looks unreal! Great idea to add rosemary.

    Awesome i so love rhubarb baked in pies, sauces, etc. I can never get enough of rhubarb dishes. My mother used to baked with dishes from our rhubarb patches that would gladly gather for her when i grew up in rural Ontario, Canada. Now living in Houston Texas now, i get very little fresh rhubarb, mainly frozen. Thanks!!

    I ended up not having enough rhubarb, so I had to add about 1/2 b of strawberries. I also doubled the ginger, used the zest of a whole lemon, squeezed in the juice, added 2 tsp of the finely chopped fresh rosemary to the filling and tripled the rosemary yo the crumble, because….I LOVE IT. And it was PERFECT. OMG ?

    This is double the water! I was too lazy to grab out my sister pie book, and started the crust using this recipe. I double checked the book- it only calls for half a cup of water.

      Hi Jacquie,
      In the Sister Pie book there are two sets of instructions for the water – one where you make the ice water ahead of time and one where you don’t. I am lazy/can never remember to do things ahead of time, so I use the latter. This calls for more water than you need in order to get the mixture ratios correct. In the recipe, I specify that you should only add the water until it comes together. You will likely have more than you need.
      Hope this clarifies!
