Strawberry-Rhubarb Slab Pie & King Arthur Flour Giveaway! {Naptime Entertaining}

Strawberry Rhubarb Slab Pie | The Naptime Chef

The Occasion: Strawberry picking weekend, casual weekend at home with lots of expected guests.

Number of People: Anywhere between 4 and 8

Menu: Strawberry-Rhubarb Slab Pie to have on hand for anyone/everyone!

Last week I took two little girls strawberry picking. Between the three of us we picked 23 pounds of fresh strawberries in under an hour. It was impressive, to say the least, and I was so proud of my little farmhands for be so discriminate in their picking. They actually followed my guidelines in the fields and only picking the brightest, reddest, strawberries they could find! Half of the loot went home with the playdate and the rest came home to our kitchen. With an exhausted child upstairs for a little quiet time I quickly set to work washing, hulling, and chopped the ruby red fruit. The first thing on my baking agenda? Pie!

I haven’t talked much about my beloved rhubarb this spring but I’ve been baking up a storm with it.  All sorts of rhubarb treats have been spilling out of the kitchen including Brown Butter Rhubarb Muffins, Rhubarb Syrup, and all kinds of cakes, including this yogurt cake made with the remains of last year’s frozen stash. With a few fresh stalks on hand and a mountain of freshly picked strawberries I set straight to work making a gorgeous Strawberry Rhubarb Slab Pie. Since I knew we would be having people in and out of the house for the weekend I decided on a slab pie instead of a regular sized one so it would last longer. I also like the way slab pies seem easier to serve, they are more like pie bars, and have such a cool rustic look to them.

While my daughter played in her room (and actually fell asleep for a quick nap) I made the crust to chill and prepared the strawberry rhubarb filling. Before dinner I rolled out the crust and put everything in the oven to bake. We rushed through our meal because we could barely wait to get to dessert. The aroma from the oven was intoxicating and the pie emerged from the oven all warm and bubbly with a gorgeous golden crust. After not-so-patiently waiting for it to cool we eagerly cut a few slices to serve with ice cream. The buttery crust was perfectly warm and flakey wrapped around the sweet tart filling. For the rest of the weekend I served slice after slice of pie to friends as they came in and out for this or that and by Monday it was nearly gone. I am not going to lie, since I didn’t want to miss out on any of its fresh glory I ate the last slice for breakfast.

To celebrate the start of pie season I am teamed up with King Arthur Flour for a terrific pie giveaway! Here is what is including in the prize package and the entry rules!

Strawberry Rhubarb Slab Pie


For the crust:

5 cups King Arthur All-Purpose flour
2 teaspoons kosher salt
2 tablespoons sugar
4 sticks (2 cups) cold unsalted butter, cut into small pieces.
1 cup ice water, or more as needed

For the filling:

6 cups fresh strawberries, washed, hulled, sliced
2 cups fresh rhubarb, washed and sliced into 1-inch pieces
3 tablespoons cornstarch
½ cup sugar
2 lemons, zested and juiced


1. In a food processor, combine the flour, salt, sugar, and butter and pulse until a small crumb forms. Remove the tube of the food processor and pulse while slowly added the ice water. Stop adding the water once a ball of dough forms. If the dough seems a little dry add a little more water bit by bit just until the dough comes together. Remove the dough from the processor and divide it in two. Form two disks with the dough and wrap them with plastic wrap. Refrigerate for one hour or up to 12.

2. Preheat the oven to 375F. Remove the dough from the refrigerator to warm slightly. In a large bowl combine the strawberries, rhubarb, cornstarch, sugar, and lemon zest and juice. Stir well and let sit while you roll out the dough.

3. On a heavily floured surface roll out one piece of dough to be 12 x 16 in size. Drape it into an 11 x 15 rimmed baking sheet and trim the edges. Roll out the second rectangle to be 11 x 15. Brush the filling into the dough and spread it evenly around. Then place the second piece of dough over the pie. Brush the edges lightly with water and seal the edges together with your finger tips. Cut a pattern or make slits in the top of the pie crust to allow it to vent while baking. It helps to place a second pan the rack below this pan, or have an oven liner in case any of the filling bubbles over.

4. Bake the pie for about 40 to 45 minutes, or until the crust is golden brown and the filling is warm and bubbly. Allow to cool for about 20 minutes before slicing and serving!

    Whatever is a “pie filling enhancer”?  I feel silly asking, since I think you’re just talking about sugar (YUM) but I’m not sure . . . . As to my favorite kind of pie, I love marionberry (my northwest roots are showing).

    • KelseyTheNaptimeChef says:

      Hi! The pie filling enhancer is KAF’s special product that thickens the pie filling perfectly and adds a few flavor notes. I use it when I can and recommend trying some if you have the chance. No more runny pies! 🙂 I love the idea of marionberry!

  10. Heather Hicks says:

    I love blueberry pie!

  11. That looks divine. I love a good fresh strawberry pie where the filling isn’t cooked. That’d be my favorite.

  12. Nicolette says:

    Favorite summer pie, hmmmmm, tough one.  Let’s see strawberry, blueberry, cherry, can’t pick so i will go with a mix of all three!!!

  25. Sarah says:

    This looks fabulous.  I want to make it for a potluck, but I don’t have and 11×15″ pan.  Would a jelly roll pan work or does it need higher sides? 

  26. Spdfish says:

    Wild Vermont blueberries of course…..

  27. Healthyjalapeno says:

    Hiiiiii! I just found you from the King Arthur Blog and Bake in VT that wrapped up last week and I was ecstatic that you are from CT… well, actually that you are from Ffld. I used to live in Trumbull and now I am in Danbury living with my fiancé and blogging away just like you. I am so excited that there is another foodie around blogging just like me. 
    Well neighbor I am definitely your newest follower!!! 🙂

  28. Heather Munson says:

    Rhubarb, for sure. No, wait, blueberry. Or what about coconut cream? Lemon? Oh, dear. Clearly there can’t be just one.

  29. Greg Allbee says:

    I would have to say a lemon icebox or a key lime pie would be my favorite.  So crisp and cool and refreshing!

  30. Karen says:

    A local eatery used to make a Fresh Fruit Ambrosia pie which was my favorite until it closed, I have never been able to reproduce it, and miss it very much.  Since it was always my dessert of choice for my birthday my family would try various different pies to replace it.  Last year while vacationing in Cancun I saw a creme brulee pie in a display at a restaurant.   I never ordered it cuz I didn’t need those calories, but my sweet husband knew I wished I had so he made me one for my birthday that year and now I have a new favorite, (though I still miss that Ambrosia pie)  He looked up  creme brulee pie on the internet and made it, it was so good.
