Summer is coming to an end, and as I'm having trouble saying goodbye, I'm comforted by all the beautiful produce still available in the farmers' markets this late in the season. Last week I visited the Tucker Square Greenmarket at the corner of Columbus Avenue and 66th Street. They are a compact market with about six or eight small yet bounteous stands. I couldn't help but notice all the fruits: last-of-the-season white and yellow peaches and a few early varieties of apples, such as honey crisp. But what really caught my attention during this visit was a crate full of beautiful green and yellow zucchini. That's when I immediately decided on making this recipe for vegetable tian.
A tian is technically a name for a type of French earthenware casserole commonly used in the region of Provençe. But the name "tian" also carries over to the meal cooked in the earthenware container. This vegetable tian is possibly one of the simplest recipes that can be made especially with an abundance of late-summer vegetables like zucchini, squash, eggplant, and tomatoes. Similar to a gratin, this casserole features layers of thinly sliced vegetables artfully assembled together, topped with Swiss cheese, and baked until tender and brown.
