A vibrant vegetarian twist on the classic Russian coulibiac, featuring roasted sweet potatoes, zesty herb-infused rice, and creamy goat's cheese. Wrapped in golden, flaky puff pastry, this dish makes a stunning centerpiece for any festive gathering or special dinner.
Preheat your oven to 200°C (180°C fan/Gas 6). Place the sweet potato chunks on a large baking tray, drizzle with oil, and season with salt and pepper. Toss well to coat and roast for 20–30 minutes until the potatoes are golden and tender. Remove from the oven and allow to cool completely.
In a large mixing bowl, combine the cooked rice, sliced spring onions, dried cranberries, chopped dill, parsley, and lemon zest. Pour in half of the lemon juice and half of the beaten egg, then mix thoroughly. Gently fold in the cooled roasted sweet potatoes, taking care not to break them up too much.
Prepare the base: Trim a quarter off one pastry block and set it aside. Roll out the remaining larger piece on a lightly floured surface into a rectangle roughly 15 x 45cm. In a small bowl, blend the goat's cheese with the remaining lemon juice to soften it, then spread it over the pastry rectangle, leaving a 2cm border around the edges.
Spoon the rice and sweet potato filling over the goat's cheese layer. Use your hands or a spoon to press the filling down firmly into a neat, smooth mound.
Assemble the top: Attach the reserved pastry trim to the second pastry block. Roll it out into a rectangle large enough to cover the entire filling. Drape the pastry over the mound and press the edges firmly to seal. Trim any excess, then crimp the edges with a fork. Brush the entire surface with the remaining beaten egg, score a decorative pattern with a sharp knife, and sprinkle with seeds.
Chill the coulibiac in the fridge for at least 30 minutes (or up to 24 hours). When ready to bake, heat the oven to 200°C (180°C fan/Gas 6) and bake for 40 minutes until the pastry is crisp and deep golden. Serve in thick slices with lingonberry sauce and a dollop of soured cream.
For the best results, ensure the sweet potatoes are completely cold before mixing them with the rice to prevent the pastry from becoming soggy. If lingonberry sauce is unavailable, a high-quality cranberry sauce provides a similar tart contrast that complements the goat's cheese perfectly.
