Sweet Potato Slab Pie Recipes

Steps:

• Fill a large pan with boiling water from the kettle and set over a medium-high heat. Cook the whole, unpeeled sweet potatoes for 30 mins until very tender when pierced with the tip of a sharp knife. Drain well and leave to cool for 10 mins, then peel.
• Heat the oven to 180C/160C fan/gas 4. Unravel the shortcrust pastry and use it to line a 23cm fluted tart tin. Line with baking parchment and fill with baking beans, then bake for 20 mins. Remove the parchment and beans and bake for another 5 mins.
• Tip the peeled sweet potatoes into a large bowl with the butter and mash with a potato masher until completely smooth. Tip in the sugar, milk, eggs, spices and vanilla and whisk until everything is combined and smooth.
• Tip the sweet potato filling into the pastry case, smoothing the top with a spatula. Bake for 50-55 mins until the pastry and the surface of the pie is golden and the middle is set. Leave to cool completely in the tin, then remove to a cake stand or serving plate and cut into slices to serve.

Steps:

• Preheat the oven to 350 degrees F.
• Put the sweet potatoes on a foil-lined half-sheet pan. Bake, turning once, until very tender, 1 1/2 to 2 hours. When cool enough to handle, take the sweet potatoes out of their jackets and scrape the flesh into a 1-quart measuring cup. You should have 2 1/2 cups packed sweet potato.
• Raise the oven temperature to 425 degrees F.
• Line the frozen dough with foil and fill with pie weights. Bake until dry and set, about 25 minutes. Remove the foil with the weights and bake the dough until golden brown, about 5 minutes longer. Let cool completely, then place on a half-sheet pan.
• Transfer the sweet potato to a large bowl and add the cinnamon, ginger, allspice, nutmeg, salt, butter, brown sugar, and the evaporated milk. Beat with a heavy whisk until smooth. Taste and add more brown sugar if you'd like. The amount will depend on the sweetness of your spuds. Add the eggs and whisk until fully incorporated. Pour into the pie crust and spread evenly.
• Bake for 15 minutes, then reduce the oven temperature to 350 degrees F. Bake until the top is golden brown and the filling has puffed and set, about 40 minutes. If the crust browns too quickly, cover it with foil and continue baking. Let cool completely on a wire rack.
• Dissolve the sugar and salt in 1/3 cup water and chill until cold.
• Pulse the flour and butter in a stand mixer until the mixture looks like coarse meal with some pea-size pieces. Add the water all at once and mix until the dough almost forms a ball. Divide the dough in half and flatten into two disks.
• Wrap each disk tightly in plastic wrap and chill until firm, at least 30 minutes or up to 3 days. You can freeze the dough for up to 3 months. Thaw overnight in the refrigerator before rolling.
