Leek and Mushroom Breakfast Tart with Salt-and-Pepper Crust

If you’re like me, you rediscover the fragrance of thyme around Thanksgiving and then spend the next few months looking for ways to incorporate the herb into every meal. This thyme-enhanced recipe—which my husband and I discovered on one of our first Christmases together and have been making ever since—has all the earmarks of a favorite: cheese stuck to the page, flour dust from my hands, a few telling drips of browned butter. You can always spot the best loved dishes by the state of the recipe card.
