I love buttermilk but I’ve raved and ranted on here more than once about the large quantities it’s sold in. There is a bright side though, if I have it in the fridge then I’m forced to make plenty more buttermilk recipes like this amazing Southern Buttermilk Slab Pie.
I reached out to my Facebook community for some ideas on how to use up the last few cups that were still in the fridge, and they didn’t let me down. They came up with some amazing recipe ideas but the most popular suggestion was to make a simple buttermilk pie. I’ve already made this version of a similar Chess Pie, so I know how good they can taste. I also know that I don’t like to make repeat recipes, just like how I never watch movies a second time- I’m weird like that.
The only way to make a pie without making a real pie is to make a slab pie! Just follow the same method you would use for making a round pie, the only change is the baking pan and the time it takes to bake. Slabs will bake faster.
The result is a buttery crust topped with a nutmeg and lemon infused custard. Easier to slice than a pie, cut these into bars and serve at room temperature dusted with powdered sugar. I like to my bars to have a thick pastry base but if you prefer a thinner version, just roll the dough out into a larger rectangle.
