Chou Farci (Stuffed Cabbage)

Directions

1. Bring a large pot of water to a boil; season generously with salt. Meanwhile, core the cabbage and separate the leaves until you get to the center, discarding any very coarse outer leaves. You should end up with 16 to 18 leaves. Working in batches if needed, cook the leaves in the boiling water for about 6 minutes, until bright green and softened. Drain and let cool.
2. While the cabbage cools, in a large Dutch oven over medium heat, heat the butter and oil until the butter melts. Add the lamb, breaking it apart with a wooden spoon, and cook, stirring occasionally, for 5 to 6 minutes, until the lamb is browned. Don’t worry if you're getting a lot of stuck-on bits; those will come up when you add the stock.
3. Add the mushrooms, onion, carrots, garlic, and thyme and cook, stirring often, for 8 to 10 minutes, until softened. Add the tomato paste, allspice, and nutmeg and cook, stirring, for another 2 minutes. Pour in the stock and scrape any stuck-on bits off the bottom of the pan; season with salt and pepper. Let the mixture simmer for about 5 minutes, until some of the liquid has absorbed. Transfer to a large bowl to let cool.
4. Butter a 9-inch springform pan. Arrange a large pretty cabbage leaf, domed side down, in the middle of the pan. If any of your leaves are too curved, simply remove the thick rib with a sharp knife. Continue arranging the leaves, shingling one on top of another, until the entire base and sides are well covered. Make sure some of the leaves hang over the sides of the pan by a few inches. You won’t use all of the leaves at this point; reserve the remaining leaves for layering with the filling.
5. Heat the oven to 350°F. Once cooled, fold the egg, breadcrumbs, and parsley into the lamb mixture; season with salt and pepper if needed. Spread one-third of the mixture in the cabbage-lined pan and top with a cabbage leaf or two to cover. Repeat with another one-third of the filling and a layer of cabbage leaves. Finish with the remaining filling and a final layer of cabbage leaves. Tuck in all the overhanging leaves toward the center and press down gently.
6. Place the pan on a sheet pan and bake for about 40 minutes, until the cabbage has pulled away from the sides and is slightly browned. Let cool for 10 minutes, then unmold by inverting a plate or round platter over the pan, flip the plate and pan, and remove the pan. Cut into slices and serve.
