I think this is my new favorite tart! It’s great for the holidays, brunch or as an appetizer with friends. Try not to get overwhelmed with the long instructions it’s really easy if you break it up into steps make the crust one day as well as caramelizing the sweet potatoes. I had extra leftover sweet potatoes so I added them into a salad and it really jazzed it up. Pasta is another easy thing you could throw them into as well.
Basic Short-Crust Pastry
(Adapted from NY Times)
145 grams all-purpose flour (about 1 cup)
½ teaspoon kosher salt
1 stick cold unsalted butter (1/4 pound), cut in 1/8-inch pieces
3 tablespoons ice water
Put flour and salt in the bowl of a stand mixer or food processor.
Add butter and quickly cut it into flour until mixture resembles coarse meal.
Add ice water and mix briefly, about 30 seconds, to form a soft dough.
Remove dough, shape into a thick disk, wrap in plastic and refrigerate for at least 2 hours or overnight. Bring to cool room temperature before rolling.
To roll, lightly flour dough and counter. Roll out gradually, periodically letting dough rest for a moment before continuing. This makes rolling easier and will keep dough from shrinking back during baking.
Roll dough to a thin round approximately 13 inches in diameter, then trim to make a 12-inch circle (refrigerate and save trimmings for patching). Lay dough loosely into a 9 1/2-inch fluted tart pan with removable bottom, letting it relax a bit. Fold overlap back inside to make a double thickness, then press firmly against the pan so the finished edge is slightly higher than the pan.
Refrigerate or freeze for an hour before pre-baking.
Sweet Potato and Feta Tart

500 g (3 1/2 cups) sweet potato peeled and cut into 1cm cubes

Salt & pepper
Preheat the oven to 200C (180C fan forced).
Place the sweet potato in a large bowl and set aside.
Mix the rosemary and garlic together on the chopping board, then continue mincing the herbs and garlic until they are both finely chopped.
Scatter the rosemary mixture over the sweet potato.
Drizzle over the olive oil, and season with salt & pepper.
Toss everything together until the sweet potato cubes are well covered with oil.
Remove from the oven and set aside.
