Tomato Tart captures the essence of vine-ripened tomatoes and is a lovely way to highlight their tangy sweet flavor. Mustard goes surprisingly well with garden tomatoes and fresh herbs, and a buttery crisp crust is the perfect platform to show them off. Everyone in the family agrees on these points.
There is vigorous debate, however, on how long to cook tomatoes for the ideal tart. I like them best when they’re just warmed through, leaving tomatoes hot, juicy, and full of fresh tomato flavor. My husband prefers them oven-roasted to concentrate their glorious summer sweetness.
Since we both like both versions, I usually make whatever I have time for. With lots of time, I make the oven-roasted tomato version; with less time, the slice and bake version. No matter the version, since tomatoes are front and center, use the best quality tomatoes you can find. During the summer tomato harvest, when juicy red tomatoes are easy to find, my thoughts always turn to Tomato Tart.
Flavor-rich Greek tomatoes inspired Tomato Tart. I first started making it in 1987 when we lived in Greece and were blessed with a garden glut of the best tomatoes I’d ever tasted. When we returned to Alaska, and were stuck with insipid supermarket tomatoes, this dish was out of reach. In recent years, however, tomatoes bursting with summer flavor have been showing up at Alaska farmers’ markets. When they’re available, Tomato Tart is on the menu.
In addition to the fresh/oven-roasted tomato variations, I’ve made Tomato Tart with regular Dijon mustard and whole-grain Dijon mustard. I’ve made it with the herbs called for in this recipe, as well as with fresh sage, fresh thyme, dried thyme, and various combinations of all or some of the herbs. I’ve made it with every kind of cheese imaginable. The constants are tomatoes, mustard, cheese, and herbs; the specifics depend solely on what’s in the refrigerator.
There’s a reason I’ve been making Tomato Tart for over 20 years. It’s delicious.
