Black and Red Raspberry Slab Pie

Okay, first let me just say that I get that this is not the most seasonal of posts, but it’s hard to hold back a berry fanatic, even in November. Second, I know I am going overboard with all these posts about slab pie, but I’m a tiny bit obsessed. Now it’s possible my obsession is just a response to having made almost nothing but icebox cakes for the last two years — a fruit-filled slab pie is about as far away as you can get from a cake made of pudding, whipped cream, and graham crackers. But I really think slab pies are kind of unusually special.

First, they are show-stoppers (a pie the size of an entire cookie sheet? I have yet to serve one in my own home or arrive at a party with one that didn’t receive excessive oohs and ahhs, and honestly, while conducting my berry slab pie recon, both this Food52 recipe and this Martha Stewart recipe elicited a silent ooh and aah from even me). Second, they are incredibly tasty (the ratio of filling to crust in a slab pie cannot be beat — think pop-tart). And third, they feed a crowd (and by a crowd, I mean as little as 8 people, going back for seconds, or as many as 20).

Now, it was kind of a given that I was going to end up making a berry slab pie (or 12), as my berry pie-thing is well documented (moreover, I had copious amounts of black and red raspberries from the garden that I had frozen). So for those of you that share such a berry-thing and are okay buying berries in the fall (“seasonal” purists, please do bookmark this til summer), I promise that you will not be disappointed. The filling is sweet-ish (from the berries and some sugar) but also quite tart from 1/4 cup of lemon juice, and the color of the berries — both before and after baking — is to die.

Now I can’t promise you that this is my last slab pie post (I am thinking about an apple cherry one, as well as a pecan pie one — both for around Thanksgiving time), but I can promise you that after tasting this one, with a scoop of vanilla ice cream perhaps, you will find yourself oohing and ahhing at your own handiwork.

  • 1/4 cup freshly squeezed lemon juice

  • Combine the berries, sugar, salt and arrow root in a large bowl. Using your hands, or a wooden spoon, toss the ingredients together until the berries absorb all of the arrow root. Add the lemon juice and toss again.

That is all I make, apple, peach, cherry and razzleberry. I got my recipes from my mother, she only made apple and I expanded when our children were growing. Nothing like a sheet pie!!
