This pie is wonderful warm or cold, and makes a great addition to a picnic with a crisp green salad.
4heirloom tomatoes (about 1kg), thinly sliced2 tbspolive oil2 tbspthyme100 gmfeta, thinly sliced200 ml eachmilk and thickened cream3eggs, lightly beaten8rashers streaky bacon (see note)Polenta pastry150 gm(1 cup) plain flour70 gmcoarse polenta120 gmchilled butter, cut into 2cm pieces½ tspapple cider vinegar
For polenta pastry, combine flour, polenta and ½ tsp salt in a large bowl. Turn out onto a work surface, scatter butter on top and cut into flour with a pastry cutter or knife until mixture resembles coarse breadcrumbs with small lumps of butter still visible. Place vinegar in a jug with 90ml iced water, drizzle onto flour mixture and use a pastry cutter or knife to combine. Bring pastry together with the heel of your hand, pat into a disc, wrap in plastic wrap and refrigerate to rest (at least 1 hour).
Meanwhile, preheat oven to 150C. Place tomatoes in a single layer on baking trays lined with baking paper, drizzle with oil, scatter with half the thyme, season to taste and roast until almost dried out (50 minutes to 1 hour). Set aside to cool.
Roll out pastry on a lightly floured surface to a 5mm-thick, 35cm-diameter round and line a 23cm shallow pie dish. Trim edges, leaving a 2cm overhang, then gently roll edge of pastry under itself to rest on edge of pie dish to create a double-layered crust and press gently to seal. Pinch pastry edge to form a crimped crust and refrigerate to rest (30 minutes).
Preheat oven to 180C. Blind-bake pie crust until edges are light golden (10-12 minutes), then remove weights and paper, and bake until base is cooked through (10-12 minutes). Cool briefly, then layer tomatoes and feta in pastry case, seasoning between layers. Whisk milk, cream, eggs, and remaining thyme in a bowl, season to taste, then pour mixture over tomatoes and feta.
Interlace bacon on a sheet of baking paper to form a lattice pattern, transfer to top of pie (don’t worry if bacon overhangs a bit; it will shrink during cooking), place pie on a baking tray and bake until golden and set (50-55 minutes). Cool slightly before serving.
Note If streaky bacon is unavailable,
substitute long middle rashers of bacon and trim to fit.
