Ingredients 8 medium leeks, white and light-green parts only 1 ¾ cups heavy cream Coarse salt and ground pepper ⅓ cup grated Pecorino Romano cheese Directions Preheat oven to 375 degrees. Halve leeks lengthwise, leaving halves attached at root, and rinse well, shaking off water. In a large skillet, combine cream and leeks; season with salt and pepper. Bring to a boil over medium-high; reduce to a medium simmer, cover, and cook 5 minutes. Uncover and simmer until leeks are tender, 15 minutes.
